2026 SE Tax Rate = 12.4% Social Security + 2.9% Medicare
Applies to net self-employment income (gross × 92.35%)

2026 SE Tax Rate Breakdown

Self-employment tax is made up of two components that mirror the FICA taxes paid by employees and employers. Here is the complete 2026 breakdown:

Component Rate Income Applies To 2026 Limit
Social Security (OASDI) 12.4% Net SE earnings First $184,500
Medicare (HI) 2.9% All net SE earnings No limit
Additional Medicare 0.9% Above $200K (single) / $250K (MFJ) No limit
Total SE Tax (up to wage base) 15.3% First $184,500 —
Total SE Tax (above wage base) 2.9% – 3.8% Above $184,500 —

Note: The Social Security wage base increases each year with inflation. In 2025 it was $176,100; in 2026 it rose to $184,500 — a $8,400 increase.

How SE Tax Is Calculated

The IRS does not simply apply 15.3% to your gross self-employment income. Instead, the calculation involves a two-step adjustment that simulates what happens with W-2 workers:

  1. Start with net profit from Schedule C (or your share of partnership income).
  2. Multiply by 92.35% to get your net earnings from self-employment. This percentage accounts for the fact that employees only pay FICA on their wages (the employer matching portion is not part of the employee's gross income).
  3. Apply 15.3% to net earnings up to the Social Security wage base ($184,500), then 2.9% on any amount above.

Worked Example: $75,000 Gross SE Income

StepCalculationAmount
Gross SE income—$75,000
Net earnings (92.35% adjustment)$75,000 × 0.9235$69,263
SE tax (under wage base)$69,263 × 15.3%$10,597
SE Tax Owed—$10,597
SE tax deduction (50%)$10,597 × 50%$5,299

SE Tax vs. Employee FICA

Self-employed individuals pay both the employee and employer share of Social Security and Medicare taxes. Here is how that compares to a regular W-2 employee:

Tax Self-Employed W-2 Employee
Social Security 12.4% (you pay all) 6.2% (employee) + 6.2% (employer)
Medicare 2.9% (you pay all) 1.45% (employee) + 1.45% (employer)
Total 15.3% 15.3% (split between you and employer)
Who writes the check? You pay all of it Split with employer

The total FICA burden is identical whether you are self-employed or a W-2 employee — 15.3% on wages up to the Social Security wage base. The difference is that self-employed individuals write one check to the IRS for the full amount, while employees only see the 7.65% withheld from their paychecks (their employer remits the other 7.65% separately).

The 92.35% Adjustment Explained

When you are a W-2 employee, your employer pays half of FICA (7.65%) on top of your salary. That employer portion is not counted as the employee's income for FICA purposes. Self-employed individuals are essentially both employer and employee, so the IRS provides a comparable adjustment.

Before calculating SE tax, you reduce your net SE income by 7.65%:

Formula: Net SE income × 0.9235 = Taxable SE earnings
Example: $100,000 × 0.9235 = $92,350 subject to SE tax

The 92.35% multiplier is derived from: 1 − 0.0765 = 0.9235. The IRS effectively lets you pretend you only earned 92.35 cents of every dollar for purposes of calculating SE tax — just as a W-2 employee is only taxed on their take-home wages, not on the employer's matching FICA contribution.

SE Tax Deduction (50%)

After calculating your SE tax, the IRS allows you to deduct 50% of your SE tax from your gross income when filing your federal income tax return. This deduction appears on Schedule 1 of Form 1040 and reduces your adjusted gross income (AGI).

  • It is an “above the line” deduction — available whether you itemize or take the standard deduction.
  • It reduces your income tax bill but does not reduce the SE tax itself.
  • Think of it as the IRS recognizing that the “employer half” of FICA is a legitimate business expense.

Example: If your SE tax is $10,597, you can deduct $5,299 from your gross income. At a 22% income tax rate, this saves you approximately $1,166 in federal income tax.

Important: The 50% SE tax deduction reduces income tax only. It does not reduce your SE tax liability itself. You still owe the full SE tax amount on Schedule SE.

2026 Social Security Wage Base: $184,500

The Social Security portion of SE tax (12.4%) only applies to net SE earnings up to the annual wage base. Once you exceed the wage base, only Medicare tax continues to apply:

  • First $184,500 in net SE earnings: 15.3% SE tax (Social Security + Medicare)
  • Above $184,500: 2.9% only (Medicare alone; no more Social Security)
  • Above $200,000 (single) / $250,000 (MFJ): An additional 0.9% Medicare surtax applies, bringing the Medicare rate to 3.8%

If you earn $200,000 in net SE income, your SE tax calculation uses the full $184,500 at 15.3%, then the remaining $15,500 at 2.9%. The Additional Medicare Tax of 0.9% kicks in separately when your total income (wages + SE income + other income) exceeds the thresholds above.

Historical SE Tax Rates

Year SE Tax Rate SS Wage Base Change
2026 15.3% $184,500 +$8,400
2025 15.3% $176,100 +$7,500

Frequently Asked Questions

The self-employment tax rate for 2026 is 15.3% on net SE earnings up to the Social Security wage base of $184,500. It is composed of 12.4% for Social Security (OASDI) and 2.9% for Medicare. Above $184,500 in net SE income, only the 2.9% Medicare portion applies. High earners above $200,000 (single) or $250,000 (married filing jointly) may also owe an additional 0.9% Medicare surtax.

No. Self-employment tax (SE tax) and federal income tax are two separate taxes. SE tax is essentially your Social Security and Medicare contributions — the equivalent of FICA for W-2 employees. Federal income tax is calculated on your taxable income using the seven tax brackets (10% through 37%). Self-employed individuals owe both taxes, which is why your total tax burden can be significantly higher than your marginal income tax bracket suggests.

The Social Security wage base for 2026 is $184,500. This is the maximum amount of net SE earnings subject to the 12.4% Social Security portion of SE tax. Once your net SE earnings exceed $184,500 in 2026, you no longer owe Social Security tax on the excess — only the 2.9% Medicare tax continues. The wage base is adjusted annually for wage inflation by the Social Security Administration.

SE tax cannot be entirely avoided if you have net self-employment income above $400. However, there are legitimate strategies to reduce it:
  • Elect S-Corp status: Pay yourself a reasonable salary (subject to FICA) and take remaining profits as distributions (not subject to SE tax). This can be a significant savings for higher earners.
  • Maximize deductible expenses: Reducing your net Schedule C profit reduces SE tax.
  • Contribute to a retirement plan: SEP-IRA or Solo 401(k) contributions reduce income tax but do not reduce SE tax (which is calculated before retirement deductions).
Consult a CPA before making structural changes to your business to ensure the savings outweigh the added complexity.

SE tax applies to your net self-employment income, not your gross revenue. Net SE income is your gross business income minus deductible business expenses (from Schedule C). Additionally, before SE tax is computed, net SE income is multiplied by 92.35% to account for the employer deduction. SE tax does not apply to W-2 wages, investment income, rental income (in most cases), or passive income.
