What tax deductions are available for construction businesses?
Vehicle expenses are usually the largest deduction for construction businesses. You can use the standard mileage rate or track actual expenses like gas, maintenance, insurance, and depreciation. Actual expenses typically save more if you drive a work truck primarily for business. Track every business mile because the IRS expects documentation.
Tools and equipment under $2,500 can be expensed immediately. Larger purchases like trucks, trailers, excavators, compressors, and specialty equipment get depreciated over time or deducted in full using Section 179. The timing of equipment purchases can significantly affect your tax bill, so planning matters.
Materials you purchase for jobs reduce your taxable income as cost of goods sold. Subcontractor payments are deductible when you issue 1099s properly. If you’re not tracking subcontractor payments and issuing 1099s, you’re creating problems for yourself and potentially losing deductions.
Insurance premiums for general liability, workers’ comp, commercial auto, tools coverage, and bonding are fully deductible. So are contractor license fees, permit fees, continuing education for license maintenance, and association dues. Bond premiums that many construction businesses pay for larger projects are also deductible.
Job site costs add up quickly and are often overlooked. Portable toilets, dumpster rentals, temporary fencing, job site trailers, safety equipment, and consumable supplies all count. These smaller expenses get forgotten by tax time if you’re not categorizing them throughout the year.
Home office deduction applies if you have a dedicated space used exclusively for business. The simplified method gives you $5 per square foot up to 300 square feet. The actual expense method can save more but requires detailed documentation of your housing costs.
Professional services including accounting, legal fees, and bookkeeping are deductible. Interest on business loans and equipment financing is deductible. Marketing costs like vehicle wraps, website expenses, and advertising are fully deductible.
The biggest issue for construction businesses isn’t the lack of deductions. It’s not tracking them. You remember the $40,000 excavator but forget the $1,200 in small tool purchases, the mileage to suppliers, and the job site supplies. By April, thousands in deductions are lost because there’s no documentation.
Working with Los Angeles QuickBooks bookkeepers who understand construction helps capture deductions throughout the year. Waiting until tax season means relying on memory and incomplete records. A few hundred dollars in missed deductions every month adds up to real money by year end.

What is accrual vs cash basis accounting and which should I use?
Cash basis records income when you receive payment and expenses when you pay them. Accrual records both when they're earned or incurred. Most small businesses use cash basis because it's simpler and offers tax timing flexibility.
