Receiving an IRS or California FTB audit notice is stressful — but contractors who maintain clean books and organized records have nothing to fear. The vast majority of small business audits are resolved quickly and favorably when the taxpayer has proper documentation. This guide explains what to expect if you’re audited as a contractor, how to prepare, and most importantly, how to build the bookkeeping systems that make audit defense simple.

Types of IRS Audits for Small Businesses

There are three main types of IRS audits. A correspondence audit is the most common — the IRS sends a letter requesting documentation for a specific item on your return (a deduction, a reported income amount, a credit). You respond by mail with supporting documents. Most correspondence audits are resolved without ever meeting an IRS agent. An office audit requires you (or your CPA/representative) to meet with an IRS examiner at a local IRS office to review specific items. A field audit is the most comprehensive — an IRS agent comes to your business to review your records. Field audits are typically reserved for more complex situations or when the IRS suspects significant issues.

What Triggers Contractor Audits

The IRS uses statistical models to flag returns with unusual patterns. Common contractor audit triggers include large Schedule C vehicle deductions, high home office deductions, consistently reporting net losses, cash income that seems inconsistent with lifestyle or bank deposits, missing or inconsistent 1099 reporting, large meals and entertainment deductions, subcontractor payments that don’t reconcile with 1099s filed, and reported income significantly below industry averages for your revenue level. The California FTB independently audits returns and may initiate California audits based on information sharing with the IRS or its own audit triggers.

What to Do When You Receive an Audit Notice

First, don’t panic — and don’t ignore it. Read the notice carefully to understand exactly what’s being examined. Note the response deadline. Contact your CPA or tax professional immediately. Don’t contact the IRS directly until you’ve spoken with your representative. Gather the records related to the items being questioned. Respond to correspondence audits with organized, labeled documentation — don’t send a disorganized pile of papers.

Gathering Your Documentation

Depending on what’s being audited, you may need to produce: QuickBooks reports and account details for the year in question, bank and credit card statements, invoices for all income reported, receipts for deductions claimed, vehicle mileage logs, home office documentation (dimensions, photos, purpose), payroll records and W-2s issued, 1099s issued to subcontractors and W-9s collected, contracts for major jobs, prior year tax returns, and business entity documents. The more organized your records, the faster and cheaper the audit process will be. Clean QuickBooks records that clearly document every transaction are far more effective than a box of unsorted receipts.

How Your Bookkeeper Helps During an Audit

A good bookkeeper is invaluable during an audit. They can pull organized QuickBooks reports on short notice, explain how transactions were recorded and why, help reconstruct any records that need clarification, and coordinate with your CPA on documentation. Contractors whose books are maintained by a professional bookkeeper consistently fare better in audits because the records are organized, consistent, and defensible. DIY bookkeeping with inconsistent categorization, unexplained transactions, and missing documentation creates audit vulnerabilities that a professional bookkeeper eliminates.

The Best Audit Defense: Proactive Records

The goal isn’t to avoid deductions — it’s to take every legitimate deduction with proper documentation. A contractor who claims $15,000 in vehicle expenses with a thorough mileage log, fuel receipts, insurance records, and maintenance documentation will win an audit on that item. A contractor who claims $15,000 without any documentation will lose it. The difference is bookkeeping discipline throughout the year, not after-the-fact scrambling in response to an audit notice.

Frequently Asked Questions

How far back can the IRS audit my tax returns?

Generally 3 years from the filing or due date of the return, whichever is later. If you underreport income by more than 25%, the window extends to 6 years. If there is fraud, there is no time limit. Keep records for at least 7 years to cover the standard and extended audit windows.

Should I represent myself in an IRS audit?

For correspondence audits with clear documentation, you may be able to handle it yourself. For office audits and field audits, always have a CPA or Enrolled Agent represent you. Tax professionals who specialize in IRS representation understand audit procedures, know what rights you have, and can negotiate effectively on your behalf. Their fee is almost always worth it.

One of the most important financial decisions a contractor makes isn’t about a specific job or client — it’s about how their business is legally structured. The right business structure provides liability protection, minimizes taxes, and positions the business for growth. The wrong structure can cost you thousands of dollars in unnecessary taxes every year and leave your personal assets exposed to business liabilities. This guide compares the three most common business structures for California contractors: sole proprietorship, LLC, and S-Corporation.

The Sole Proprietorship: Simple but Limited

A sole proprietorship is the default structure for anyone doing business without formally establishing a separate entity. If you obtained your CSLB license as an individual and never formed an LLC or corporation, you’re a sole proprietor. Business income is reported on Schedule C of your personal tax return. There’s no separation between you and your business — legally or financially.

The sole proprietorship’s biggest drawbacks are liability exposure and self-employment tax. On the liability side, there’s no separation between business and personal assets — a judgment against your business is a judgment against you personally, putting your home, savings, and personal property at risk. On the tax side, all net profit is subject to self-employment tax (15.3% on the first $160,200 in 2023, then 2.9% above that) plus federal and California income taxes. For a contractor netting $150,000, that’s over $22,000 in self-employment taxes alone.

The LLC: Essential Liability Protection

A California LLC (Limited Liability Company) provides a critical layer of protection between your business and your personal assets. If the business is sued or faces a judgment, your personal home, savings, and personal property are generally protected — as long as you maintain proper separation between business and personal finances (separate bank accounts, separate expenses, no commingling).

By default, a single-member LLC is taxed as a sole proprietor (Schedule C) and a multi-member LLC is taxed as a partnership. The liability protection is there, but the self-employment tax is the same as a sole proprietor. California adds an $800/year minimum franchise tax for LLCs, plus a graduated annual LLC fee based on gross revenue (starting at $900 for revenue over $250,000). Despite these costs, every contractor doing meaningful revenue should have an LLC for the liability protection alone — the cost of not having it is far greater than the cost of maintaining it.

The S-Corporation: The Tax Efficiency Structure

An S-Corporation is not a separate business entity — it’s a tax election that an LLC or corporation makes with the IRS. A California contractor typically forms an LLC, then elects S-Corp tax status. This changes how the business income is taxed in a significant way: instead of all profits being subject to self-employment tax, an S-Corp owner pays themselves a “reasonable salary” (subject to payroll taxes) and takes the remaining profit as a distribution (not subject to self-employment tax).

Example: A contractor netting $180,000/year. As a sole proprietor or LLC taxed as sole proprietor, all $180,000 is subject to SE tax — roughly $25,000. As an S-Corp with a $80,000 reasonable salary, only $80,000 is subject to payroll taxes — roughly $12,000. The distribution of the remaining $100,000 is not subject to self-employment tax, saving approximately $13,000/year. Over a career, this is hundreds of thousands of dollars in tax savings.

The S-Corp election adds administrative requirements: you must run formal payroll for yourself, file a separate business tax return (Form 1120-S), and maintain more rigorous corporate formalities. California also imposes an additional 1.5% state franchise tax on S-Corp net income (minimum $800). But for contractors netting $80,000+ per year, the S-Corp typically saves significant net tax even after these additional costs.

Which Structure Is Right for Your Contracting Business?

If you’re just starting out with modest revenue (under $50,000/year net), start with an LLC for liability protection. The tax efficiency of an S-Corp doesn’t outweigh the administrative costs at this income level. As revenue grows and net profit consistently exceeds $60,000–$80,000/year, analyze the S-Corp election with your CPA. The analysis should compare total taxes in both structures, including California franchise taxes, payroll administration costs, and bookkeeping costs for the more complex structure. At $100,000–$200,000+ in net profit, the S-Corp almost always wins on a net tax basis for California contractors.

CSLB Licensing and Business Structure

When you change your business structure, you may need to update your CSLB license. A license issued to an individual does not automatically transfer to an LLC or corporation — you need a new entity license. The entity must have a Qualifying Individual (RMO or RME) who holds the appropriate license classification. Work with a CSLB-experienced attorney or licensing consultant to handle the entity license properly, and ensure your bond and insurance are updated to reflect the new entity name.

Frequently Asked Questions

How do I elect S-Corp status for my existing LLC?

File IRS Form 2553 (Election by a Small Business Corporation) with the IRS. The election can be made anytime during the prior tax year or by March 15 of the current tax year for it to be effective for the current year. Late elections are sometimes accepted with reasonable cause. For California, file FTB Form 3560. Work with your CPA to make the election correctly and set up payroll immediately upon S-Corp election.

What is a “reasonable salary” for an S-Corp contractor?

The IRS requires S-Corp owner-employees to pay themselves a reasonable salary for their services to the business. “Reasonable” is generally interpreted as what you would pay someone else to do your job. For contractors doing the work themselves, this might be in the range of $60,000–$100,000 depending on your trade, experience, and the going market rate for your services. Your CPA should help you determine a defensible reasonable salary for your specific situation.

Chasing payments is one of the most frustrating parts of running a contracting business. You’ve done the work, delivered the quality, met the deadline — and now you’re spending time calling, emailing, and waiting for money you’ve already earned. For many contractors, outstanding accounts receivable is their biggest asset — and their biggest headache. This guide shows you how to build accounts receivable systems that minimize payment delays, reduce disputes, and ensure you get paid on time without damaging client relationships.

What Is Accounts Receivable for Contractors?

Accounts receivable (AR) is money owed to you by clients for work you’ve completed but haven’t yet been paid for. On your QuickBooks Balance Sheet, AR appears as a current asset — it’s money you’ve earned that will (hopefully) convert to cash in the near future. For contractors, AR often includes outstanding invoices for completed work, unbilled work in progress (earned but not yet invoiced), and retainage — the percentage withheld until project completion. Tracking all of these accurately in QuickBooks gives you a complete picture of what’s owed to you at any moment.

The AR Aging Report: Your Most Important Collections Tool

The Accounts Receivable Aging Report in QuickBooks shows all outstanding invoices grouped by how long they’ve been outstanding: Current (not yet due), 1–30 days past due, 31–60 days past due, 61–90 days past due, and 90+ days past due. Review this report weekly. Invoices in the 31–60 day column need immediate attention — the longer an invoice ages, the harder it becomes to collect. Invoices in the 90+ column are serious collection risks. Don’t let the report grow without acting on it.

Building Your AR Follow-Up System

Inconsistent follow-up is the primary reason contractors don’t get paid on time. Here’s a systematic approach: On invoice date, send the invoice by email with a professional message and confirmation request. Three days before due date, send an automated reminder through QuickBooks Payments or email. On the due date, verify payment was received. Day 1 past due: send a polite past-due reminder by email. Day 5 past due: follow up by phone — don’t just rely on email. A phone call communicates urgency that email doesn’t. Day 15 past due: send a formal demand letter. Day 30 past due: issue a Preliminary Notice (if not already sent) and seriously consider mechanics lien recording. Day 60+ past due: engage a collections attorney or collections agency, and evaluate whether to file suit.

Preventing AR Problems Before They Start

The best AR strategy is prevention. Require deposits before starting work — typically 30–50% for residential, 10–25% for commercial, depending on your relationship with the client. Verify credit for new commercial clients before starting work. Get a signed contract with clear payment terms before mobilizing. Include late payment fee provisions in your contracts. On larger jobs, use progress billing to collect throughout the project rather than waiting for one large payment at the end. Qualify your clients — contractors who are selective about the clients they work for have dramatically fewer collection problems than those who take every job that comes their way.

Using Mechanics Liens to Accelerate Payment

In California, contractors have powerful lien rights that provide significant leverage in collections. When a client is 30+ days past due on a significant invoice, filing a mechanics lien on the property often accelerates payment quickly. Owners cannot sell or refinance a property with a recorded lien, which creates strong incentive to resolve the debt. The mechanics lien process requires serving a Preliminary Notice within 20 days of starting work — if you haven’t done this, you may have lost lien rights for earlier work. Going forward, serve Preliminary Notices on every project as a standard procedure, not just when you think there might be a problem.

Setting Up AR Correctly in QuickBooks

In QuickBooks Online, accounts receivable is managed through Invoices (create an invoice when work is performed or a milestone is reached), Payments (apply client payments to the correct invoices), and the Customers module (view outstanding balances by client). Set up automated payment reminders in QuickBooks to send reminder emails before and after due dates automatically. QuickBooks Payments allows clients to pay by credit card or ACH directly from the invoice email — reducing payment friction significantly. Track retainage in a separate Retainage Receivable account so your AR aging report shows current invoices separately from withheld retainage.

Frequently Asked Questions

How do I write off a bad debt in QuickBooks?

If an invoice is uncollectible, you can write it off as a bad debt expense in QuickBooks. Create a Bad Debt expense account in your Chart of Accounts. Then create a credit memo for the uncollectible amount against the client, using the Bad Debt account as the category. Apply the credit memo to the outstanding invoice to zero it out. The bad debt expense reduces your taxable income by the uncollected amount (if you’re on accrual accounting — on cash basis, you never recognized the income, so there’s no deduction).

Workers’ compensation insurance is one of the most significant costs — and most significant legal obligations — for contractors with employees in California. California has some of the highest workers’ comp rates in the country, particularly for construction trades. Understanding how workers’ comp works, how rates are calculated, and how to manage costs can save your business thousands of dollars per year while keeping you fully compliant with California law.

Who Needs Workers’ Compensation in California?

Any California employer with one or more employees — even one part-time worker — is required by law to carry workers’ compensation insurance. California Labor Code Section 3700 mandates workers’ comp coverage for all employees. There are no exceptions for small employers, no minimum hours thresholds, and no grace periods. The requirement exists from the moment you have your first employee. Operating without required workers’ comp is a misdemeanor in California punishable by fines up to $100,000 and potential imprisonment. The CSLB can also suspend your contractor’s license for failure to maintain workers’ comp.

How Workers’ Comp Rates Work for Contractors

Workers’ comp premiums are calculated as a rate per $100 of payroll for each job classification. Construction trades carry some of the highest rates because the work involves physical risk. For reference, approximate base rates in California (these vary by insurer and experience modification): roofing installation is $20–$35 per $100; framing/carpentry is $12–$20; painting is $6–$12; HVAC installation is $8–$15; plumbing is $8–$14; electrical is $6–$12; landscaping/tree work is $8–$18; and general building contractor is $8–$15. On a crew with $400,000 in annual payroll doing framing work, workers’ comp at $15/$100 is $60,000/year. This massive cost must be built into every job estimate.

The Experience Modification Rate (EMR)

Your workers’ comp premium is multiplied by your Experience Modification Rate (EMR), also called the “mod.” An EMR of 1.00 means average — your rate is exactly the base rate. An EMR below 1.00 (say, 0.85) means you have better-than-average claims history and you get a discount. An EMR above 1.00 (say, 1.25) means worse-than-average claims history and you pay a surcharge. A single serious workers’ comp claim can elevate your EMR for 3 years, significantly increasing your premiums. This is why job site safety isn’t just the right thing to do — it’s financially critical.

Workers’ Comp Audits: What to Expect

Workers’ comp policies are issued based on estimated payroll at the beginning of the policy year. At year end, the insurer conducts a premium audit — they review your actual payroll to see if it matched the estimate. If actual payroll is higher than estimated, you’ll owe additional premium. If lower, you’ll receive a credit. To prepare for audit: keep detailed payroll records in QuickBooks, maintain accurate time records by employee and job classification, separate office/clerical staff payroll from field labor (clerical rates are dramatically lower), document any subcontractor payments and verify their insurance certificates (uninsured subs may be treated as your employees in an audit), and have certificates of insurance from all subcontractors on file.

Workers’ Comp for Subcontractors — A Critical Risk

If you use subcontractors who don’t carry their own workers’ comp insurance, California law may treat their workers as your employees for workers’ comp purposes. This means you could be liable for workers’ comp claims from uninsured subcontractors’ workers — even though you never considered them your employees. Always obtain current certificates of insurance from every subcontractor before they start work. Store these in QuickBooks or a dedicated file, and verify they remain current throughout the project. This one practice protects you from enormous potential liability.

Sole Proprietor and LLC Owner Exemptions

In California, sole proprietors and LLC owners who are not corporate officers may exclude themselves from workers’ comp coverage for their own labor. If you’re a sole proprietor working by yourself with no employees, you don’t need workers’ comp for yourself (though you may want it as a safety net). If you form an LLC and are the sole member, the same exclusion may apply. However, the moment you have even one employee, coverage is required for them. And some clients (GCs, commercial property owners) require you to carry workers’ comp regardless, even if you technically qualify for an exclusion.

Tracking Workers’ Comp Costs in QuickBooks

Workers’ comp premiums should be tracked in QuickBooks as a business expense. For accurate job costing, allocate workers’ comp costs as a direct labor cost — include it in your labor burden rate when calculating job estimates. Your labor burden rate is the true cost of an hour of labor: base wage plus payroll taxes (FICA, FUTA, SUI) plus workers’ comp plus any benefits. Tracking labor burden correctly is essential for accurate bidding — contractors who only count base wages in their labor estimates consistently underestimate job costs.

Frequently Asked Questions

What happens if an employee gets hurt and I don’t have workers’ comp?

You are personally liable for all medical expenses, lost wages, and rehabilitation costs. You also face criminal prosecution, fines, and CSLB license suspension. The California Labor Commissioner can issue a stop order shutting down your operations. The financial exposure from a single serious injury can bankrupt a small contractor. Workers’ comp is not optional.

How can I reduce my workers’ comp premiums?

Maintain a strong safety program to reduce claims and improve your EMR over time. Correctly classify employees (misclassification can mean overpaying premium for high-rate classes). Consider a pay-as-you-go workers’ comp policy where premiums are calculated on actual payroll each payroll period rather than estimated annually. Shop your coverage annually with an independent insurance broker who specializes in construction.

Most contractors price their services one of two ways: they guess based on what they think the client will pay, or they look at what competitors charge and price similarly. Both approaches are financially dangerous. The right way to price your services as a contractor is based on your actual costs — not market rates alone — with a built-in overhead recovery and profit margin that makes your business financially sustainable. This guide gives you a bookkeeper’s perspective on contractor pricing: how to calculate your real costs, determine your necessary markup, and use job cost data to refine your pricing over time.

Why Most Contractors Under-Price Their Work

The most common pricing mistake is failing to account for all costs. Contractors typically account for direct labor and materials — the visible costs — but miss indirect costs that are just as real: the cost of driving to job sites, the time spent estimating jobs that don’t close, workers’ comp on job labor, general liability insurance allocated per job, equipment depreciation, and the cost of their own time managing projects. When you add up all the true costs of completing a job, many contractors discover they’ve been pricing work at near-breakeven or worse. The jobs felt profitable because cash was coming in — but the business wasn’t generating real net profit.

Step 1: Calculate Your True Hourly Labor Cost

Your billable labor rate must cover more than the employee’s wage. The full cost of an hour of field labor includes the base wage, plus payroll taxes (FICA employer share 7.65%, FUTA ~0.6%, California SUI typically 1.5–5%), plus workers’ comp (varies by trade — roofing is $25–$35/$100 of wages, painting is $6–$12/$100), plus any benefits (health insurance, paid time off), plus a share of direct supervision time. This “fully loaded” or “burdened” labor rate is what each labor hour actually costs your business. For a painter earning $25/hour, the fully loaded cost might be $35–$40/hour once all costs are added. This is the number that goes into your job cost estimates — not $25/hour.

Step 2: Know Your Overhead Rate

Your overhead rate is the percentage of revenue required to cover all overhead expenses — the costs of running your business that aren’t tied to a specific job. Calculate it from your Profit & Loss in QuickBooks: divide total annual overhead expenses by total annual revenue. If your overhead is $150,000 and revenue is $500,000, your overhead rate is 30%. Every dollar of revenue you generate carries 30 cents of overhead cost before you see any profit. Your bids must include overhead recovery on top of direct job costs.

Step 3: Add Your Target Profit Margin

After covering direct costs and overhead, you need a profit margin. For most contractors in the LA market, a net profit margin of 10–15% is a realistic target for a well-run business. This is your reward for the risk you take as a business owner, your capital for reinvestment, and your cushion for unexpected costs. Build your target profit margin explicitly into every bid — don’t hope it shows up after the fact. A typical contractor markup calculation looks like this: direct job costs are $10,000. Overhead at 30% adds $3,000. Subtotal is $13,000. Profit at 15% adds $1,950. Bid price is $14,950.

Using Job Cost Data to Refine Your Pricing

The most powerful pricing tool is your own job cost data from QuickBooks. After running Projects (job costing) for 6–12 months, you have real data showing actual costs versus estimated costs for each job type. Run the Project Profitability report and analyze: which types of jobs consistently hit or beat your target margin, which types consistently fall short, where the overruns are coming from (labor, materials, or both), and what your actual average cost per unit is for your most common work types. This data transforms your bidding from estimation to precision. You’ll know exactly where you can be competitive and where you need to charge more — and you’ll have data to support your pricing to clients who push back on your rates.

Value-Based Pricing vs. Cost-Plus Pricing

Cost-plus pricing (direct costs + overhead + profit = bid price) ensures you never lose money on a job. Value-based pricing means charging based on the value you deliver to the client, which may allow higher margins on certain work types. For commodity services (basic residential maintenance, simple repairs), competitive market pricing dominates — you can’t charge dramatically above market rates. For specialized work (complex commercial projects, specialty systems, high-end residential), where your expertise and quality create real value for the client, value-based pricing can support premium rates well above your cost-plus floor. Understand where you are on this spectrum for each service line you offer.

Frequently Asked Questions

How do I know if my prices are competitive?

Get competitive intelligence by requesting quotes from competitors on work where you’ve lost bids, networking with other contractors in non-competing markets, and reviewing industry cost surveys. But remember: if you’re winning every bid, you’re probably priced too low. A healthy close rate for most contractors is 30–50% of bids submitted — if it’s higher, raise your prices.

What should I do when a client says my price is too high?

Don’t immediately discount. First, understand the objection — is it genuinely price, or is it uncertainty about your value? Explain what’s included in your price, your qualifications and warranty, and how you’re different from lower-priced competitors. If the client is comparing you to someone with no insurance or license, that’s a legitimate differentiation. If you genuinely need to compete on price, reduce scope rather than margin — cut something out of the bid rather than working for less.

California contractors pay some of the highest combined federal and state tax rates in the country. Federal self-employment tax, federal income tax, and California state income tax can combine to take 35–45% of your net profit. The only legal way to reduce this burden is to claim every deduction you’re entitled to — and that requires knowing what’s deductible, documenting it properly, and having a bookkeeper who captures every dollar throughout the year. This guide is your comprehensive list of tax deductions for California contractors.

Vehicle and Transportation Deductions

Vehicles are often the largest individual deduction for contractors. You have two options for each vehicle: actual expenses or the standard mileage rate. Actual expenses include fuel, insurance, registration fees, repairs and maintenance, car washes, and depreciation (or Section 179 for the purchase year). Standard mileage rate for 2024 is 67 cents per mile. For contractors who own work trucks and drive high annual business mileage, actual expenses almost always produce a larger deduction. Track actual expenses in QuickBooks throughout the year and keep a mileage log to document business use percentage. Under Section 179, you may be able to deduct the full purchase price of a qualifying work truck or SUV (over 6,000 lbs GVWR) in the year purchased.

Equipment and Tools

All tools and equipment used for your contracting business are deductible. For major equipment purchases (over $2,500), you have two options: capitalize and depreciate over the asset’s useful life (5–7 years for most equipment), or use Section 179 to deduct the full cost in the year of purchase (up to $1,160,000 in 2024). Section 179 is almost always better for cash flow and tax savings. Bonus depreciation (60% for 2024) applies to the remaining basis after Section 179 if needed. For small tools and equipment under $2,500 each, the IRS de minimis safe harbor allows you to deduct them as current expenses without capitalizing — this is extremely useful for contractors who regularly buy hand tools, small power tools, and supplies.

Home Office Deduction

If you have a dedicated space in your home used exclusively and regularly for business administration — writing estimates, handling billing, record-keeping, client calls — you may qualify for the home office deduction. You can use the simplified method ($5/sqft, up to 300 sqft, maximum $1,500/year) or the actual expense method (percentage of home expenses based on office square footage). The actual expense method allows you to deduct a proportionate share of mortgage interest or rent, utilities, insurance, repairs, and depreciation. For contractors working primarily from home offices, the actual expense method often produces larger deductions.

Business Insurance Premiums

All business insurance premiums are fully deductible: general liability insurance, workers’ compensation insurance, commercial auto insurance, tools and equipment insurance, builder’s risk insurance, professional liability, and umbrella liability. Track all insurance premium payments in QuickBooks under an Insurance expense account and ensure they’re deducted on your tax return.

Retirement Contributions

Retirement contributions are one of the most powerful contractor deductions — they reduce your taxable income dollar-for-dollar while building your future wealth. A SEP-IRA allows contributions up to 25% of net self-employment income (up to $69,000 in 2024). A Solo 401(k) allows up to $23,000 in employee deferrals plus 25% of compensation as employer contributions (up to $69,000 total). These contributions are deductible on your federal return and on your California return (with some differences for California’s own treatment). A contractor earning $200,000 in net profit who maximizes a SEP-IRA contributes $46,250 — saving potentially $15,000–$20,000 in combined taxes.

Professional Services

Bookkeeping fees, accounting fees, CPA fees, legal fees, and other professional service costs related to your business are fully deductible. This includes your monthly bookkeeping service, annual tax return preparation, legal fees for contract review or dispute resolution, and any consulting fees paid to business advisors. These deductions mean your professional services effectively cost significantly less than their invoice amount.

Licenses and Permits

All business licenses and permit costs are deductible: your CSLB license fees and renewal costs, your contractor’s bond premium, your city and county business license fees, DIR registration fees for public works, permit fees for specific jobs (these are job costs — deductible as cost of services), and any professional certification or continuing education costs required to maintain your license.

Marketing and Advertising

All marketing expenses are deductible: your business website and hosting fees, Google Ads and Local Service Ads, Yelp advertising, Angi (formerly Angie’s List) memberships, social media advertising, business cards and printed materials, vehicle wraps and signage, trade show or event fees, and promotional items. Track all marketing costs in a dedicated Marketing/Advertising account in QuickBooks.

Uniforms and protective clothing (items not suitable for everyday wear), safety equipment (hard hats, safety glasses, steel-toe boots), cell phone and data plan used for business (percentage of business use), business software and app subscriptions, office supplies, postage and shipping, trade association memberships and dues, industry publications and subscriptions, business meals with clients or prospects (50% deductible — note the business purpose), education and training costs, and bank fees on your business accounts are all deductible. Make sure every one of these is tracked in QuickBooks throughout the year so your CPA can claim them on your return.

Frequently Asked Questions

Can I deduct my cell phone as a contractor?

Yes — the business use percentage of your cell phone and data plan is deductible. If you use your phone 80% for business, you can deduct 80% of your monthly bill. Keep a record of how you determined the business use percentage in case of an audit. Many contractors use their phone almost exclusively for business, which supports a high deduction percentage.

Are subcontractor payments tax deductible?

Yes. Payments to subcontractors for business work are fully deductible as cost of services. You must issue a 1099-NEC to any unincorporated sub you pay $600 or more in a year and have a signed W-9 on file. Track all subcontractor payments in QuickBooks under a Subcontractor expense account.

Running a general contracting business means managing multiple jobs simultaneously — multiple crews, multiple subcontractors, multiple clients, multiple payment schedules, and multiple cost streams all running at the same time. Without robust bookkeeping systems, the financial picture of your business becomes a blur. You can’t tell which jobs are making money and which are losing it. You don’t know when cash will be tight. You can’t see subcontractor balances across projects. This guide covers the bookkeeping practices that general contractors need to manage multiple jobs without losing financial control.

The Core Challenge: Financial Visibility Across Multiple Projects

The defining challenge for a general contractor’s bookkeeping is that your business is actually a portfolio of mini-businesses (individual projects), each with its own budget, cost stream, billing schedule, and profitability. Managing them in aggregate — without project-level visibility — means you’re always reacting rather than managing. Profitable GC operations require seeing revenue, costs, and margins at the project level so you can identify which jobs are over budget, which are behind on billing, and which are most profitable — in real time, not at job close.

Setting Up QuickBooks for Multi-Job GC Operations

For a general contractor, QuickBooks setup is more complex than for a specialty trade. Your Chart of Accounts needs separate income categories for each contract type (residential remodel, commercial TI, new construction, etc.). More importantly, every job must be set up as a QuickBooks Project from day one. The Project tracks all revenue billed, all direct costs (labor, materials, subs, permits, equipment), and calculates your gross margin by project. The Projects dashboard gives you a real-time snapshot of all active jobs — their budget, costs to date, and profitability. This is your command center as a GC.

Managing Subcontractors in QuickBooks

Subcontractor management is the most complex bookkeeping challenge for general contractors. Best practices include: set up each sub as a Vendor in QuickBooks with their W-9 information, insurance certificate expiration dates, and CSLB license number; enter every subcontract as a purchase order in QuickBooks so you track committed costs against each project; enter all sub invoices as bills in QuickBooks and assign them to the correct project; pay subs only after verifying their lien release (conditional waiver when payment is issued, unconditional after it clears); and track 1099 totals throughout the year in QuickBooks so year-end 1099 preparation is automatic. At year-end, the 1099 report in QuickBooks shows all unincorporated subs paid $600+ — no manual calculation required.

Progress Billing and Draw Management

GC jobs with durations of more than a few weeks require progress billing — scheduled invoices tied to project milestones or completion percentage. In QuickBooks, use the Progress Invoicing feature to create invoices based on a percentage of the original estimate, specific line items completed, or a custom schedule. This ensures you’re billing at the right times and tracking how much you’ve billed versus how much you’ve completed — a critical metric for avoiding over-billing or under-billing situations. Track retainage receivable (amounts withheld by the owner) in a separate QuickBooks account so it appears clearly on your balance sheet.

Job Cost Variance Analysis

The most valuable analysis a GC can run is the cost variance report: actual costs to date versus budget for each active job, categorized by cost type (labor, materials, subs, equipment). Run this weekly during construction. Any variance over 10% in any category deserves investigation. Labor overruns early in a job often predict a money-losing project — address them immediately with crew efficiency discussions, scope adjustments, or change orders. Material overruns may indicate waste, theft, or incorrect material quantities in your original estimate — both need to be corrected. Catching variances early gives you the ability to course-correct. Catching them at job close doesn’t.

Cash Flow Management Across Multiple Jobs

Running multiple jobs simultaneously creates complex cash flow patterns. You might be mobilizing on a new job (cash out for materials and labor) while waiting for a progress payment on an older job. Maintaining a 13-week cash flow forecast — updated weekly — is the tool that gives GCs visibility into upcoming cash needs and surpluses. In QuickBooks, you can use the Customer and Vendor Center to see all outstanding receivables and payables by due date, giving you the inputs for a cash flow forecast. Maintain a revolving business line of credit as a backup for timing gaps — this is standard practice for growing GC operations.

Frequently Asked Questions

How do I track committed costs (subcontract obligations) in QuickBooks?

Use Purchase Orders in QuickBooks for each subcontract. Enter the full subcontract value as a purchase order assigned to the project. As the sub invoices you, enter each invoice as a bill against the purchase order. QuickBooks tracks the committed amount, the billed amount, and the remaining balance — giving you a complete picture of your cost exposure per sub per job.

How often should I reconcile my books as a GC with multiple jobs?

Bank reconciliation should happen monthly — every month, without exception. Job cost review (comparing actual to budget) should happen weekly during active construction. AR aging review should happen weekly. Full financial statement review should happen monthly. With a professional bookkeeper handling the month-end close, you can focus on the weekly operational reviews that drive project profitability.

The Profit and Loss Statement (P&L) — also called the Income Statement — is the most fundamental financial report in your business. It tells you whether your business made or lost money during a specific period. Yet many small business owners and contractors never look at theirs, don’t know how to read it, or stare at the numbers without knowing what they mean. This guide teaches you to read your P&L confidently and use it to make better business decisions.

What Is a Profit and Loss Statement?

A Profit and Loss Statement summarizes your business’s financial performance over a period of time — typically a month, quarter, or year. It shows all of your income earned, all of your costs and expenses, and the resulting profit or loss. Unlike the Balance Sheet (which shows what you own and owe at a specific point in time), the P&L shows what happened over a period of time — it’s a movie of your business’s financial performance, not a snapshot. For contractors, the P&L is the primary tool for understanding whether your business is actually profitable — not just busy.

The Structure of a Contractor’s P&L

A well-organized contractor P&L has four main sections: Revenue (Income), Cost of Goods Sold (Direct Job Costs), Gross Profit, Operating Expenses (Overhead), and Net Profit.

Section 1: Revenue

Revenue is the total amount billed to clients for work performed during the period. For contractors on cash basis, this is when payments are received. For accrual basis, it’s when work is performed and invoiced. Your QuickBooks P&L can show revenue by service type if your Chart of Accounts is set up correctly — residential vs. commercial, different trades, service vs. installation. This segmentation reveals which work types drive your revenue growth.

Section 2: Cost of Goods Sold (Direct Job Costs)

Cost of Goods Sold (COGS) on a contractor’s P&L represents the direct costs of completing jobs: field labor (wages for crew members doing the work), materials and supplies, subcontractor costs, equipment rental for specific jobs, and permit fees. COGS are the costs that vary with revenue — more jobs means more direct costs. Revenue minus COGS equals Gross Profit.

Section 3: Gross Profit and Gross Margin

Gross Profit = Revenue – COGS. Gross Margin = Gross Profit / Revenue × 100%. This is the most important line on your P&L. Gross margin is the percentage of revenue left after paying direct job costs — it’s the margin available to cover overhead and generate profit. For most contractors, healthy gross margins range from 25–40%. If your gross margin is below 20%, you’re not charging enough for your work, your costs are too high, or both. Watch this number closely — a declining gross margin is an early warning signal that something is wrong with your pricing or job costs.

Section 4: Operating Expenses (Overhead)

Operating expenses are the costs of running your business that aren’t tied to specific jobs: owner’s salary or management compensation, office rent or home office, insurance (general liability, commercial auto), vehicle expenses (non-job-specific), bookkeeping and accounting fees, marketing and advertising, software subscriptions, tools and equipment (non-job-specific), and miscellaneous business expenses. Unlike direct job costs, overhead is relatively fixed — it doesn’t go down much when revenue is slow, which is why cash reserves are so important for contractors.

Section 5: Net Profit (or Loss)

Net Profit = Gross Profit – Operating Expenses. This is the bottom line — what the business earned after all costs. For contractors, a net profit margin of 8–15% is generally healthy. A negative net profit means the business is losing money — either gross margins are too low or overhead is too high (or both). Understanding which is driving the loss points you to the solution.

Key Metrics to Track on Your P&L

When you review your P&L monthly, focus on four key metrics: gross margin percentage (healthy for your trade and trending correctly), overhead as a percentage of revenue (stable or declining as revenue grows — economies of scale should improve this over time), net profit margin (8–15% target for most contractors), and revenue growth year-over-year (compare each month to the same month last year to understand true growth trends, stripping out seasonality).

Common P&L Problems and What They Mean

Revenue is growing but profit is shrinking: overhead is growing faster than revenue — investigate and cut unnecessary overhead. Gross margin is declining: job costs are increasing faster than revenue — review pricing and job cost data for overruns. Net profit is positive but cash is always tight: timing differences between when you earn revenue and when you collect it — an accounts receivable problem, not a profitability problem. Revenue is flat year-over-year: growth has stalled — evaluate your pipeline, marketing, and capacity utilization.

Frequently Asked Questions

How often should I review my P&L?

Monthly — every month, without exception. Your bookkeeper should close the prior month and deliver financial statements within the first 10 days of the new month. Schedule a 30-minute financial review on the same day each month to review your P&L, Balance Sheet, and job cost reports. This single habit creates more financial clarity than any other practice.

What’s the difference between the P&L and cash flow?

The P&L shows profitability — revenue earned minus expenses incurred. Cash flow shows actual cash movement — money in and money out. On accrual accounting, you can be profitable (positive P&L) but cash-poor (negative cash flow) if clients are slow to pay or you paid bills before collecting. On cash basis, the P&L and cash flow are more closely aligned. Understanding both is important — the P&L tells you if the business model is working; the cash flow statement tells you if you’ll have money in the bank next month.

Setting up payroll for the first time is one of the most stressful transitions a growing contractor makes. California has some of the most complex payroll requirements in the country — daily overtime rules, multiple state tax accounts, mandatory paid sick leave, and strict record-keeping obligations. Getting payroll right from the start protects you from penalties, back taxes, and employee disputes. This guide covers everything small contractors in California need to know about payroll.

California Payroll Basics

California employers must withhold and remit several taxes for each employee: Federal income tax (based on W-4), Social Security (6.2% employee + 6.2% employer), Medicare (1.45% employee + 1.45% employer), California state income tax (based on DE 4), California SDI (State Disability Insurance — 1.1% of wages, employee paid), and employer-paid FUTA (federal unemployment) and California SUI (state unemployment insurance). You also pay California ETT (Employment Training Tax — 0.1% on first $7,000 of wages). These obligations require regular deposits — don’t let them accumulate unpaid.

California’s Daily Overtime Rule

This is the most commonly violated payroll rule for California contractors. Federal law requires overtime pay only after 40 hours in a workweek. California law requires overtime pay for hours over 8 in a single workday, regardless of weekly total. An employee who works 4 ten-hour days has worked 40 hours total — no federal overtime. But under California law, 2 hours per day × 4 days = 8 hours of daily overtime at 1.5x rate. Double-time applies for hours over 12 in a single day. This California-specific rule dramatically increases labor costs for contractors who use long daily shifts and must be built into your job cost estimates.

Setting Up California Payroll Step by Step

Register with the IRS for an EIN if not already done (irs.gov, free, 10 minutes). Register with the California EDD as a new employer at edd.ca.gov within 15 days of paying $100 or more in wages. Set up your payroll system — QuickBooks Payroll is the best integrated option for contractors already using QuickBooks for bookkeeping. Set up each employee in QuickBooks Payroll with their W-4, DE 4, job title, pay rate, and direct deposit information. Set up payroll tax deposit schedule (IRS assigns you a deposit schedule — monthly or semi-weekly — based on your tax liability). Set up QuickBooks Payroll to auto-file federal and California payroll tax returns on schedule.

Pay Frequency and Pay Stubs

California law requires you to pay employees at least twice per month (semi-monthly) or more frequently. Weekly and bi-weekly payroll are most common for construction crews. California requires detailed itemized pay stubs showing gross wages, each deduction type and amount, net wages, inclusive dates of the pay period, employee name and SSN (last 4 digits), employer name and address, and hours worked at each rate. QuickBooks Payroll generates compliant California pay stubs automatically. Failure to provide proper pay stubs is a California Labor Code violation with per-pay-period penalties.

California Paid Sick Leave

California’s Healthy Workplaces, Healthy Families Act requires employers to provide at least 5 days (40 hours) of paid sick leave per year to employees who work 30+ days in California. Sick leave accrues at 1 hour per 30 hours worked, or can be front-loaded at the beginning of the year. Unused sick leave must be carried over (up to a cap). California requires employers to show sick leave balances on pay stubs. QuickBooks Payroll tracks sick leave accrual automatically when configured correctly.

Frequently Asked Questions

When are California payroll taxes due?

Federal payroll tax deposit due dates depend on your deposit schedule (monthly or semi-weekly). California EDD payroll taxes are typically due quarterly with Form DE 9 (or more frequently for larger employers). QuickBooks Payroll tracks these deadlines and can file automatically. Never miss a deposit deadline — penalties start at 2% and increase rapidly.

Your CSLB license is one of your most valuable business assets as a California contractor. Losing it — or having it suspended — can shut down your business overnight. What many contractors don’t realize is that financial record-keeping and compliance play a significant role in maintaining your CSLB license in good standing. This guide covers the CSLB’s financial requirements and how proper bookkeeping supports your license compliance.

CSLB Financial Requirements for Licensed Contractors

The California Contractors State License Board requires licensed contractors to maintain several financial protections as a condition of licensure. The contractor’s license bond is a $25,000 surety bond required for all contractor licenses. It protects consumers — not you — from contractor failures to complete work or other violations. Your bond must remain current at all times. Cancellation or expiration immediately invalidates your license. Workers’ compensation insurance is required for any contractor with employees. You must maintain a current certificate of insurance on file with the CSLB. When coverage lapses, CSLB suspends your license — often without warning. Financial solvency is also relevant: contractors must not be insolvent or bankrupt in a way that impairs their ability to perform contracts. While the CSLB doesn’t review your books directly, financial difficulties that lead to project abandonment can result in disciplinary action.

What Happens When You Employ Workers Without Workers’ Comp?

The CSLB takes workers’ comp violations seriously. If you employ workers without coverage, the CSLB can suspend your license immediately upon notification from the EDD or a complaint. The license remains suspended until you provide proof of coverage and pay any reinstatement fees. For active contractors with jobs in progress, a license suspension can be catastrophic — you can’t legally bill for new work, and existing contracts may be in breach. Keep your workers’ comp certificate current and update CSLB immediately when coverage changes or renews.

CSLB Record-Keeping Requirements

California law requires licensed contractors to maintain business records for inspection upon request. This includes contracts and change orders for all jobs, invoices and receipts for materials and labor, payroll records, tax records, and licensing documentation. Under Business and Professions Code Section 7111, failure to maintain required records can constitute grounds for disciplinary action. More practically, clean business records protect you in client disputes, wage claims, tax audits, and any CSLB investigation.

License Bond and CSLB Disciplinary Actions

The CSLB tracks disciplinary actions, citations, and judgments against contractors. Financial judgments for non-payment of workers, suppliers, or subcontractors — if unpaid — can result in CSLB disciplinary action including license suspension. Mechanics lien actions that result in judgments against you and remain unpaid can also trigger CSLB action. Maintaining clean financial records, paying your subs and suppliers, and resolving any financial disputes promptly protects your license. Your bookkeeper’s role in tracking accounts payable and ensuring subcontractor payments are current is directly connected to your license security.

How QuickBooks Supports CSLB Compliance

A well-maintained QuickBooks system provides the documentation infrastructure to support CSLB compliance. Clean accounts payable records show that subs and suppliers are paid. Payroll records demonstrate proper employee classification and wage payment. Organized contract and invoice files (stored digitally in QuickBooks or associated systems) are available for inspection. Workers’ comp and liability insurance premium records confirm coverage was in place. Regular bookkeeping doesn’t just help your taxes — it creates the paper trail that protects your license in any regulatory or legal situation.

Frequently Asked Questions

How do I update my workers’ comp certificate with CSLB?

Your insurance carrier can file the certificate of insurance directly with CSLB electronically. When you renew your policy or change carriers, ensure your new carrier files the updated certificate with CSLB immediately — don’t let there be any gap in the filing. Log into CSLB’s Contractor’s License Check at cslb.ca.gov to verify your workers’ comp status shows as “on file.”
