How to Calculate Self-Employment Tax
- Start with net profit from Schedule C, Schedule F or partnership self-employment income.
- Multiply by 92.35% to get net earnings from self-employment.
- Apply 12.4% to earnings up to the wage base, minus any W-2 wages that already paid Social Security tax.
- Apply 2.9% to all net earnings.
- Report it on Schedule SE and carry it to Schedule 2. Deduct half on Schedule 1.
Examples
Freelancer: $60,000 of net profit times 92.35% is $55,410. At 15.3%, self-employment tax is about $8,478, and half, about $4,239, is deductible.
High earner: A single consultant with $250,000 of net profit has $230,875 of net earnings. Social Security tax is 12.4% of $184,500, or $22,878. Medicare tax is 2.9% of $230,875, or $6,695. The 0.9% Additional Medicare Tax on $30,875 above $200,000 adds about $278, for a total of roughly $29,851.
W-2 job plus side business: If you earn $150,000 in wages and $50,000 of side profit, only $34,500 of the side earnings ($184,500 minus $150,000) is subject to the 12.4% Social Security portion. All of it is subject to Medicare tax.
Who Pays Self-Employment Tax?
- Sole proprietors and single-member LLCs.
- General partners and many LLC members on their share of partnership income.
- Independent contractors, freelancers and gig workers.
- Farmers on Schedule F profit.
S corporation owners do not pay self-employment tax on distributions; they pay payroll tax on a reasonable salary instead. See how much S corporation owners should pay themselves.
Ways to Lower Self-Employment Tax 2026
- Claim every business expense. Mileage at 72.5 cents per mile, a home office, equipment and software all lower net profit. See self-employment tax deductions.
- Consider an S corporation election once profit is high enough that payroll savings exceed added costs.
- Hire your children in a family sole proprietorship; wages to children under 18 are generally not subject to Social Security and Medicare tax, if the work and pay are legitimate.
- Remember what does not help: Retirement contributions, the self-employed health insurance deduction and the QBI deduction reduce income tax but not self-employment tax.
Self-Employment Tax 2026 for Partners and LLC Members
General partners and most members of multi-member LLCs taxed as partnerships pay self-employment tax on their share of ordinary business income and on guaranteed payments, reported to them on Schedule K-1. Limited partners generally pay it only on guaranteed payments for services. The line between active LLC members and limited partners has been the subject of IRS litigation, so owners who treat part of their income as exempt should get professional advice.
Common Mistakes
- Forgetting to multiply by 92.35% before applying the 15.3% rate.
- Not coordinating the Social Security wage base when you also have a W-2 job, which can lead to overpaying.
- Skipping quarterly estimates and paying an underpayment penalty.
- Assuming retirement contributions or the QBI deduction reduce self-employment tax.
- Not deducting half of self-employment tax on Schedule 1.
Paying Self-Employment Tax During the Year
There is no withholding on self-employment income, so you pay it with income tax through quarterly estimates. For the 2026 tax year, the last payment is due January 15, 2027. See 2026 quarterly tax payments.
Benefits You Earn
