Contractor Tax Deductions

You can deduct vehicle costs using either the standard mileage rate or actual expenses (gas, insurance, repairs, depreciation) — pick whichever method gives the bigger deduction and stick with the rules for switching methods later. Tools, equipment, and even a work vehicle can often be deducted in full the year you buy them under Section 179 rules rather than depreciated slowly over several years, which matters a lot for cash flow in a growth year.

Continuing education and license renewal fees, business insurance premiums, a portion of your phone and internet bill used for work, software subscriptions (estimating, accounting, scheduling tools), safety gear and uniforms, and a genuine home office used regularly for admin work are all deductible but frequently forgotten because they don't feel like 'business expenses' in the moment.

Interest on a business loan or credit card used for materials or equipment is deductible too — many contractors miss this because they're focused on the principal payment, not the interest portion.

A deduction without a receipt or a documented business purpose is a deduction you'll lose in an audit. A simple habit — photographing receipts the day you get them and tagging the expense in your bookkeeping app — protects every deduction above without adding real time to your week.
