Self-Employed Tax Deductions: The Complete 2025 Checklist
Who this guide is for
This guide is for sole proprietors, 1099 contractors, and anyone filing Schedule C with their federal tax return. If you receive a 1099-NEC or 1099-K — or run any business under your own name without a separate business entity — you file Schedule C and you qualify for every deduction on this page.
Self-employed workers face a unique tax burden: in addition to income tax, you pay self-employment (SE) tax of 15.3% on your net earnings. That makes deductions doubly valuable — they reduce income subject to both taxes. A $1,000 deduction doesn't just save $220 in income tax (22% bracket); it also saves $153 in SE tax, for a combined savings of $373.
The five most impactful deductions
You can deduct half of your self-employment tax from your gross income. This above-the-line deduction is available even if you don't itemize.
Self-employed individuals can deduct 100% of health, dental, and vision insurance premiums for themselves and their family — as long as they weren't eligible for employer-sponsored coverage.
Contributions to a SEP-IRA, Solo 401(k), or SIMPLE IRA are deductible. SEP-IRA allows contributions up to 25% of net self-employment income (up to $69,000 in 2025).
A dedicated workspace used exclusively and regularly for business qualifies. Deduct a percentage of rent/mortgage, utilities, and insurance equal to the office's share of your home's square footage.
Business miles at $0.70/mile (2025 IRS rate) or actual vehicle expenses. Commuting never counts. Keep a mileage log with dates, destinations, and business purpose.
