Tax Deductions Checklist
Contractor Tax Deductions Checklist (2026)
2026 tax deduction checklist for self-employed general contractors. Claim write-offs on tools, materials, vehicle costs, subcontractor payments, insurance, and licensing fees.
Key Takeaways
- Keep a separate folder (physical or digital) for each project that includes the estimate, contract, permits, material receipts, sub invoices, and final invoice. This job-costing approach makes tax prep easy and provides strong audit documentation.
- If you purchase a work truck that weighs over 6,000 lbs GVWR, you may qualify for the Section 179 heavy vehicle deduction, allowing you to deduct a substantial portion of the purchase price in the first year.
- Consider using construction-specific accounting software (like QuickBooks Contractor or Buildertrend) that tracks expenses by job. This simplifies tax prep and gives you real-time profitability data on each project.
As a self-employed general contractor, your tools, building materials, work vehicle, subcontractor payments, and licensing fees all represent significant business deductions. Whether you handle remodels, new construction, or specialty work, the IRS allows you to write off the costs of running your contracting business. This checklist covers all the deductions available to independent contractors in 2026.
Use this interactive checklist to review every deduction you might be eligible for. Check off items as you go to track your progress. Each deduction includes the Schedule C line where it belongs, plus a concrete example specific to your profession.

Common Mistakes to Avoid
Not issuing 1099-NEC forms to subcontractors paid $600 or more during the year.
Collect a W-9 from every subcontractor before making the first payment. Issue 1099-NEC forms by January 31 for the prior year. Failure to file can result in penalties.
Forgetting to deduct small consumable supplies like fasteners, tape, caulk, and trash bags.
Open a charge account at your local hardware or building supply store. Monthly statements make it easy to total consumable expenses at year-end.
Not separating material costs that are reimbursed by clients from those paid out of pocket.
Only deduct materials you paid for and were not reimbursed. If a client pays you a lump sum that includes materials, the full amount is income and the materials are your deductible expense.
Overlooking dump fees, dumpster rentals, and waste removal as deductible expenses.
Keep receipts for every dump run and dumpster rental. These costs can total thousands of dollars per year on demolition and remodeling projects.
Mixing personal and business vehicle use without maintaining a mileage log.
Track business miles daily using an app or logbook. If your truck is used 100% for work, document that with a written statement and keep it with your tax records.
