What is the 2026 Social Security wage base?

The Social Security Administration set the 2026 wage base at $184,500. Self-employment income above this amount is not subject to the 12.4% Social Security tax, but all SE income remains subject to the 2.9% Medicare tax.

Why is the rate 15.3% instead of 7.65%?

W-2 employees pay 7.65% while their employer matches with another 7.65%. Self-employed individuals pay both halves, totaling 15.3%. However, you can deduct the employer-equivalent half when calculating income tax.

What This Calculator Does

This calculator computes the full self-employment tax obligation for independent workers, including Social Security tax, Medicare tax, the additional Medicare surtax, and federal income tax. It uses 2026 IRS rates with the Social Security wage base of $184,500 and progressive federal income tax brackets.

The Formula

SE Tax = (Net Profit x 92.35%) x 15.3% | Federal Tax = Brackets applied to (Net Profit - SE Deduction - Standard Deduction)

Self-employed individuals pay both the employer and employee portions of FICA taxes, totaling 15.3% (12.4% Social Security + 2.9% Medicare). The 92.35% factor mirrors the employee-equivalent calculation. Half of the SE tax is deductible when computing federal income tax. For 2026, the Social Security wage base is $184,500 and the standard deduction is $16,100 for single filers.

Step-by-Step Example

Enter net self-employment profit

This is your gross revenue minus all allowable business expenses. Example: $120,000 net profit.

Calculate SE taxable income

$120,000 x 92.35% = $110,820. This is the base for FICA taxes.

Compute Social Security and Medicare

SS: $110,820 x 12.4% = $13,742. Medicare: $110,820 x 2.9% = $3,214. Total SE tax: $16,956.

Calculate federal income tax

Deduct half of SE tax ($8,478) and standard deduction ($16,100) from net profit. Apply 2026 brackets to the remaining taxable income.
