FICA for Employees vs. Self-Employed
W-2 employees pay 7.65% FICA (6.2% Social Security + 1.45% Medicare), matched by their employer. Neither the employee's portion nor the employer match is deductible on the employee's personal return. Self-employed individuals pay the full 15.3% as self-employment tax, but get to deduct the employer-equivalent half (7.65%) on Schedule 1 of Form 1040. This reduces adjusted gross income.Social Security Wage Base
The Social Security portion (6.2% employee / 12.4% self-employed) only applies to earnings up to the annual wage base: $176,100 for 2025. Earnings above this threshold are not subject to Social Security tax. The Medicare portion (1.45% employee / 2.9% self-employed) has no wage cap — it applies to all earnings. An additional 0.9% Medicare surtax applies to wages/SE income over $200,000 ($250,000 married filing jointly).
Where to Report the Deduction
Self-employed individuals report the deductible half of SE tax on Schedule 1 (Form 1040), Line 15. This is an above-the-line deduction, meaning you get it whether you itemize or take the standard deduction. It reduces your AGI, which can positively affect other deductions and credits that phase out at higher income levels.

Example: Freelancer FICA Calculation
You earn $120,000 net profit from freelancing. SE tax base: $120,000 x 92.35% = $110,820. SE tax: $110,820 x 15.3% = $16,955. Deductible half: $8,478. This $8,478 reduces your AGI to $111,522, potentially saving you another $2,000-3,000 in income tax depending on your bracket. Total tax benefit of the deduction: roughly $2,800 at the 32% bracket.
