Key facts about self employment tax in the US
Self employment tax is based on your net earnings from self employment, not your gross receipts. Net earnings are generally your business income minus ordinary and necessary business expenses.
The standard self employment tax rate combines 12.4% Social Security tax up to the wage base and 2.9% Medicare tax on all net earnings after the 92.35% factor. Higher earners may also owe additional Medicare tax.
You can usually claim an income adjustment equal to one half of your self employment tax. This does not reduce self employment tax itself, but it can reduce the income subject to federal income tax.
Self employment tax is in addition to federal and state income taxes. Use this calculator together with an income tax calculator or paycheck tools when planning your full 2026 tax picture.

How the 2026 self employment tax calculator works
The calculator takes your 2026 net self employment income or your gross income minus deductible expenses and converts it into annual net earnings from self employment. It uses this amount for both Social Security and Medicare self employment tax calculations.
IRS Schedule SE generally treats 92.35% of your net self employment income as net earnings. The calculator multiplies your net income by this factor before applying the Social Security and Medicare self employment tax rates for 2026.
Social Security self employment tax is based on 12.4% of your net earnings up to the Social Security wage base. If you also have W2 wages, the calculator combines those wages with your self employment net earnings when checking the wage base limit. Only the portion below the wage base is subject to Social Security self employment tax.
Medicare self employment tax is calculated at 2.9% of your net earnings from self employment. The tool highlights where additional Medicare tax might apply for higher earners based on the threshold you enter, but full additional Medicare tax rules depend on total earned income and filing status.
The calculator shows an estimated above the line deduction equal to half of your total self employment tax. This does not reduce the self employment tax itself, but you can usually claim it as an adjustment to income on your federal return, subject to IRS rules.
This tool focuses on self employment tax only. It does not calculate full federal or state income tax, itemized deductions, credits, or other taxes. Use it together with the income tax calculator, federal tax calculator, or paycheck tools on USAJobsKit and consult IRS instructions and a tax professional for detailed filing support.
