Minnesota Self-Employment Tax Calculator

Calculate federal SE tax plus Minnesota state tax on self-employment income.

Combines the 15.3% federal self-employment tax (12.4% Social Security up to the wage base plus 2.9% Medicare) with Minnesota's graduated income tax on net earnings, including the deductible half-of-SE-tax adjustment, for an accurate total.

What is the self-employment tax rate?

The federal self-employment tax is 15.3% — 12.4% for Social Security on earnings up to the annual wage base (168,600 dollars in 2024) and 2.9% for Medicare with no cap. It is applied to 92.35% of your net self-employment income.

If you are self-employed in Minnesota you owe two layers of tax: the federal 15.3% self-employment (SE) tax that funds Social Security and Medicare, and Minnesota’s graduated state income tax on the same earnings. This calculator computes both correctly, including the 92.35% adjustment, the Social Security wage cap, and the deduction for half of your SE tax.

How it works

The calculation follows IRS Schedule SE and Minnesota Form M1:

  1. Net earnings. Multiply your net self-employment income by 0.9235 to get net earnings subject to SE tax.
  2. Federal SE tax. Apply 12.4% Social Security to net earnings up to the wage base ($168,600 for 2024) and 2.9% Medicare to all net earnings. Together this is the 15.3% SE tax.
  3. Half-SE-tax deduction. Subtract one-half of the SE tax from income, then apply Minnesota’s graduated brackets and standard deduction to the remainder.

The SE-tax formula is SE = (0.9235 × net) × 12.4% (capped) + (0.9235 × net) × 2.9%. Minnesota income tax is then computed on net − half_SE − standard_deduction.

Tips and example

A freelancer with $60,000 net profit has net earnings of $55,410 (92.35%). SE tax is $55,410 × 15.3% = $8,478. Half of that, $4,239, is deducted, leaving roughly $55,761. After the single standard deduction of $14,575, Minnesota taxable income is about $41,186, producing roughly $2,341 of state tax — for a combined burden near $10,819.

This estimate excludes the qualified business income deduction, self-employed health insurance and retirement adjustments, and Minnesota credits. Quarterly estimated payments are usually required to avoid underpayment penalties.
