Freelancer Taxes Explained — 2026
As a freelancer, you’re both employee and employer, which means you pay the full 15.3% self-employment tax on net profit (up to $184,500 for Social Security). But you get a deduction for half of it — reducing your taxable income before federal brackets apply.
How SE Tax Is Calculated
- Step 1: Net Profit = Revenue − Business Expenses
- Step 2: SE Tax Base = Net Profit × 92.35% (notional employee share)
- Step 3: SE Tax = SE Tax Base × 15.3% (12.4% SS + 2.9% Medicare)
- Step 4: Deduct ½ SE Tax from AGI before applying income tax brackets
- Step 5: Apply 2026 federal brackets to remaining taxable income
Top Deductions for Freelancers
- Home office (proportional to workspace square footage)
- Software, subscriptions, and professional tools
- Business travel and mileage ($0.70/mile for 2026)
- Health insurance premiums (100% deductible if no employer coverage)
- SEP-IRA contributions (up to 25% of net profit, max $72,000)
- Professional development, courses, and books
- Business phone and internet (proportional use)
What is the self-employment tax rate for 2026?+
The SE tax rate is 15.3% — composed of 12.4% Social Security (on the first $184,500 of net earnings) and 2.9% Medicare (unlimited). High earners above $200K (single) / $250K (married) also pay the 0.9% Additional Medicare Tax. SE tax is calculated on 92.35% of net profit, not 100%.
Do I have to pay quarterly estimated taxes?+
Yes, if you expect to owe $1,000 or more in federal taxes for the year. The IRS requires quarterly payments to avoid underpayment penalties. Use Form 1040-ES to calculate and pay online at IRS Direct Pay. Your state likely has its own quarterly requirement too. Missing payments costs ~7–8% annualized penalty plus interest.
Can I deduct my home office?+
Yes, using either the simplified method ($5/sq ft, max 300 sq ft = $1,500/yr) or the regular method (% of home used for business × actual expenses like rent, utilities, insurance). The space must be used regularly and exclusively for business. This is one of the most valuable deductions available to freelancers.
What’s the best retirement account for freelancers?+
SEP-IRA: Contribute up to 25% of net self-employment income, max $72,000 (2026). Solo 401(k): Employee contributions up to $24,500 + employer contributions up to 25% of net income = max $72,000 total. Solo 401k allows catch-up contributions if 50+ and is better for lower net income situations. Both reduce your taxable income dollar-for-dollar.
