Tax Write-Offs for Independent Contractors
General contractors, specialty tradespeople, and subcontractors who receive 1099s are self-employed. The wide range of deductible tools, vehicle costs, materials, and licensing fees means contractors often have the highest write-offs of any profession on this list.
Top 6 Tax Write-Offs for Independent Contractors
Tools & Equipment
100% deductiblePower tools, hand tools, measuring equipment, and specialty gear required for your trade. Tools under $2,500 can be expensed immediately; larger items use Section 179 or depreciation.
Vehicle & Mileage to Job Sites
100% deductibleMiles driven from your home or shop to job sites, supply houses, and permit offices at $0.70/mile. If your first trip of the day is to a regular job site, those miles may not be deductible — consult a CPA.
Materials & Supplies
100% deductibleLumber, concrete, pipe, wire, fasteners, and other materials you purchase to complete jobs and bill through to clients. Track separately from equipment.
Subcontractor Payments
100% deductiblePayments to subcontractors, specialty tradespeople, and laborers you hire for specific jobs. File 1099-NEC for any individual paid $600 or more in a year.
Licensing & Bond Fees
100% deductibleState contractor license fees, license renewal costs, and surety bond premiums are 100% deductible as professional expenses.
Work Clothing & Safety Gear
100% deductibleProtective equipment (hard hats, safety glasses, steel-toed boots, gloves, high-vis vests) that is not suitable for everyday wear. Standard clothing worn on the job is generally not deductible.
Common Mistakes to Avoid
- Deducting materials purchased speculatively (stockpiling supplies before you have jobs) — only materials for actual jobs in progress qualify.
- Not filing 1099-NEC forms for subcontractors — the IRS matches these and failing to file can result in penalties.
- Deducting the cost of a new truck in full without understanding the Section 179 limit for heavy vehicles, which differs from standard equipment.
- Treating your general liability insurance premium as a personal expense — it's fully deductible on Line 15.
Recordkeeping Tips
- Maintain a job log showing the client, job address, dates worked, and materials used — this provides the business purpose documentation for all job-related expenses.
- Keep all supply house and hardware store receipts separated by job so materials can be linked to specific projects.
- Log mileage every time you drive to a new job site — a mileage app with location tagging works well.
- File all 1099-NEC forms for subs by January 31 each year and keep copies with your tax records.
