Contractor Tax Deductions: The Complete List for 2026
By BRIX Editorial Team · Updated
Self-employed contractors can deduct ordinary and necessary business expenses on Schedule C, including vehicle costs, tools and equipment, materials, subcontractor payments, insurance, licenses, phone, advertising, a qualifying home office and half of self-employment tax. Every deduction lowers both income tax and self-employment tax, and each one needs records: a receipt, invoice, log or statement.
Key takeaways
- A deductible business expense is one that's ordinary (common in your trade) and necessary (helpful and appropriate), per IRS Publication 334.
- The biggest deductions for most contractors are vehicles, equipment (via Section 179 or 100% bonus depreciation), materials and subcontractor labor.
- Business meals are generally 50% deductible; entertainment isn't deductible at all.
- Retirement contributions, self-employed health insurance, half of SE tax and the 20% QBI deduction come off on Form 1040, not Schedule C, but still cut your tax.
- Starting with payments made in 2026, you issue Form 1099-NEC to subcontractors you paid $2,000 or more in the year.
What makes an expense deductible?
Publication 334 sets the test: a business expense must be ordinary, meaning common and accepted in your trade, and necessary, meaning helpful and appropriate for your business. It doesn't have to be indispensable. Personal, living and family expenses never qualify, and mixed-use items like a phone or truck are deductible only for the business share.
Every dollar you deduct on Schedule C lowers your net profit, which cuts income tax and self-employment tax. For an owner in the 22% bracket, a $1,000 deduction saves roughly $220 of income tax plus about $141 of SE tax.

What contractors can't deduct
- Commuting from home to your regular shop, however far.
- Entertainment: tickets, golf, club dues.
- Everyday clothing, even if you only wear it to work.
- Fines and penalties paid to a government, such as OSHA fines or parking tickets.
- Personal share of a mixed-use phone, truck or home.
- Federal income tax and the SE tax itself (other than the half-SE adjustment).
- Unpaid invoices if you're on the cash method; you never reported the income, so there's nothing to deduct.
Deductions by trade
| Trade | Often-missed deductions |
|---|---|
| HVAC | EPA 608 and NATE certification fees, refrigerant recovery equipment, manufacturer training, dispatch software |
| Plumbing | Sewer camera and jetter financing interest, drain-cleaning cable replacements, backflow tester calibration |

Records you need for each deduction
The IRS can disallow a legitimate expense you can't prove. Keep receipts or invoices showing what you bought, when, and from whom; bank and card statements; a mileage log; subcontractor W-9s and 1099s; and your asset list with in-service dates. Categorize expenses as they happen, not in April.
Common mistakes
- Running business expenses through a personal card and losing track of them.
- Deducting 100% of a personal-use truck or phone.
- Forgetting the above-the-line deductions like retirement and health insurance because they aren't on Schedule C.
- Not sending 1099-NECs, which can cost penalties and draws attention to the deduction.
- Claiming a home office that isn't exclusive-use.

Frequently asked questions
What can a self-employed contractor write off?
Ordinary and necessary business expenses: vehicle costs, tools and equipment, materials, subcontractor and employee pay, insurance, licenses, phone, software, advertising, professional fees, a qualifying home office and 50% of business meals. Retirement contributions, health insurance premiums and half of SE tax are deducted on Form 1040.
Can contractors deduct tools?
Yes. Tools costing up to $2,500 per item or invoice can be expensed right away under the de minimis safe harbor if you elect it. Bigger tools and equipment can be deducted in year one with Section 179 (up to $2,560,000 for 2026) or 100% bonus depreciation, or depreciated over their recovery period.
Can I deduct work clothes and boots?
Protective gear required for the job, such as hard hats, steel-toe boots, safety glasses and gloves, is deductible. Ordinary clothing you could wear outside work, like jeans and plain T-shirts, isn't, even if you only wear it on the job.
Are meals deductible for contractors?
Business meals are generally 50% deductible, including meals while traveling away from home overnight and meals with customers or suppliers where business is discussed. Entertainment expenses aren't deductible. Keep the receipt and note who you met and why.
Can I deduct my truck payment?
Not the payment itself. You deduct the business share of the truck's cost through depreciation, Section 179 or bonus depreciation, plus the business share of loan interest, or you use the standard mileage rate, which includes depreciation. Lease payments are deductible for the business share if you use actual expenses.
Do I have to send 1099s to subcontractors to deduct what I paid them?
The deduction and the 1099 are separate requirements, but skipping the 1099 can bring penalties and scrutiny. For payments made after 2025, you must issue Form 1099-NEC to each non-corporate subcontractor you paid $2,000 or more during the year.
What deductions reduce self-employment tax?
Any Schedule C business expense reduces net profit and therefore SE tax: vehicle, equipment, materials, labor, insurance, home office and the rest. The half-SE-tax deduction, retirement contributions, health insurance and the QBI deduction lower income tax only.
