Estimate Freelance Taxes
Calculate estimated quarterly taxes including self-employment tax for freelancers.
Formula
Self-Employment Tax = Net SE Income × 92.35% × 15.3% Estimated Tax = Income Tax + Self-Employment Tax Quarterly Payment = Estimated Annual Tax / 4
How to Calculate
As a freelancer, you owe both income tax and self-employment (SE) tax. SE tax covers Social Security (12.4%) and Medicare (2.9%), totaling 15.3%. Employees only pay half because their employer covers the other half—but freelancers pay both halves.
First, calculate your net self-employment income: gross revenue minus business deductions (home office, supplies, mileage, software, etc.). Then multiply by 92.35% (you get to deduct the employer-equivalent half of SE tax before calculating). Apply the 15.3% SE tax rate to this adjusted figure.
For income tax, add your SE income to any other income, subtract the standard deduction and half of your SE tax (an above-the-line deduction), and apply federal tax brackets. Add state income tax if applicable. Combine income tax and SE tax, then divide by four for quarterly estimated payments due April 15, June 15, September 15, and January 15.
Worked Example
A freelance writer earned $90,000 in gross revenue with $15,000 in business deductions.
Net SE income: $90,000 − $15,000 = $75,000 SE tax base: $75,000 × 92.35% = $69,263 SE tax: $69,263 × 15.3% = $10,597
For income tax (single filer, 2025 brackets): Adjusted gross income: $75,000 − ($10,597 / 2) = $69,702 After standard deduction ($15,000): Taxable income ≈ $54,702 Federal income tax ≈ $7,660
Total estimated tax: $10,597 + $7,660 = $18,257 Quarterly payment: $18,257 / 4 ≈ $4,564
Why It Matters
Freelancers who do not plan for taxes face a painful surprise at filing time. The IRS expects you to pay estimated taxes quarterly—failure to do so results in underpayment penalties. Understanding your true tax burden also helps you price your services correctly and set aside the right percentage from each payment you receive.
Practical Tips
- ✓Set aside 25–35% of every payment into a separate savings account for taxes.
- ✓Maximize deductions: home office, mileage, health insurance premiums, retirement contributions, and professional development.
- ✓Consider forming an S-Corp once your net income exceeds $50,000–$60,000 to potentially reduce SE tax.
- ✓Use accounting software to track income and expenses in real time—not at tax time.
