Contractor Tax Deductions Guide (1099 & Self-Employed)

Independent contractors pay both halves of Social Security and Medicare on net profit. Aggressive — and accurate — deduction tracking is how 1099 earners cut that bill.

Top deductions for contractors

  • Vehicle and mileage for client and job-site travel
  • Tools, equipment, and PPE
  • Subcontractor payments (issue 1099-NEC if over $600)
  • Job materials and supplies
  • Phone, internet, and software used for the work
  • Continuing education, licenses, and certifications
  • Self-employed health insurance and retirement contributions

Recordkeeping habits that survive an audit

  • Separate bank account and card for the business
  • Mileage log captured the same day (app or notebook)
  • Digital receipts saved with vendor, amount, and purpose
  • Contracts and change orders saved with the customer file
