How to Use This Self-Employment Tax Calculator
- 1
Enter your net self-employment income
This is your gross business revenue minus business expenses (Schedule C profit). The calculator applies the 92.35% multiplier that the IRS uses to calculate the SE tax base.
- 2
Enter any W-2 wages (if applicable)
If you also have W-2 employment, those wages reduce the amount of self-employment income subject to Social Security tax (the $168,600 wage base cap for 2026).
- 3
Review the tax breakdown
Self-employment tax is 15.3% (12.4% Social Security + 2.9% Medicare) on 92.35% of net income. The 0.9% Additional Medicare Tax applies to combined income above $200,000 (single) / $250,000 (married filing jointly).
- 4
Check the deduction
You can deduct 50% of self-employment tax from your adjusted gross income — this reduces your income tax (but not the SE tax itself). The calculator shows this deduction automatically.
Example Calculation
Let's calculate self-employment tax for a freelancer in Tax.
A freelance web developer earns $95,000 net self-employment income (after deducting business expenses). SE tax base: $95,000 × 0.9235 = $87,733. Social Security portion (12.4%): $10,879. Medicare portion (2.9%): $2,544. Total SE tax: $13,423. The 50% deduction ($6,712) reduces AGI for income tax purposes.
Result: Total self-employment tax: $13,423 (14.1% effective rate on net income). Plus federal income tax on $88,288 ($95,000 − $6,712 SE deduction) and Tax income tax if applicable. Many first-time freelancers are shocked by SE tax — it's the "employer's half" of FICA that W-2 employees never see. Quarterly estimated payments (Form 1040-ES) are required to avoid penalties.
What Affects Your Results
Net Self-Employment Income
Only net income (gross revenue minus business expenses) is subject to SE tax. Aggressive but legitimate deductions (home office, vehicle, equipment, insurance) directly reduce the tax.
Social Security Wage Base
The 12.4% Social Security portion applies only to the first $168,600 of combined wages and SE income (2026). Income above this threshold is subject to Medicare tax only (2.9-3.8%).
Filing Status
Self-employment tax is calculated individually regardless of filing status, but the Additional Medicare Tax threshold varies: $200,000 (single), $250,000 (married filing jointly), $125,000 (married filing separately).
Business Structure
Sole proprietors and single-member LLCs pay SE tax on all net income. S-Corps and C-Corps have different tax treatment — S-Corp distributions are not subject to SE tax (but salary must be "reasonable").
State Requirements
Tax may have additional business taxes (franchise tax, gross receipts tax, B&O tax) that apply on top of federal SE tax and state income tax. Check your state's business tax requirements.
Tips for Tax Residents
- Make quarterly estimated tax payments (April 15, June 15, September 15, January 15) to avoid underpayment penalties. Calculate each payment as 25% of expected annual tax.
- Maximize business deductions to reduce your SE tax base: home office (simplified method: $5/sq ft, up to 300 sq ft), health insurance premiums (100% deductible for self-employed), retirement contributions, and vehicle expenses.
- Consider an S-Corp election if net income exceeds ~$50,000. Paying yourself a "reasonable salary" (subject to payroll tax) and taking remaining profit as distributions (not subject to SE tax) can save $5,000-$15,000+/year in SE tax.
- Check if Tax has additional self-employment taxes or requirements. Some states impose gross receipts taxes, Business & Occupation taxes, or local business license fees on top of income and SE taxes.
- A Solo 401(k) lets you contribute up to $23,500 (employee) + 25% of net SE income (employer), up to $70,000 total for 2026. This shelters income from both income tax and can reduce your SE tax base if structured correctly.
