Does Wyoming have a state self-employment or income tax?

No. Wyoming has no individual income tax, so self-employment profit is subject only to the federal SE tax. The only tax this calculator computes on your business profit is the federal self-employment tax (Social Security + Medicare). You may still owe federal income tax, which is calculated separately.

Wyoming Self-Employment Tax Calculator 2025

If you are a freelancer, 1099 contractor, gig worker, or sole proprietor in Wyoming, you pay self-employment (SE) tax — your share of Social Security and Medicare, reported on Schedule SE. Because Wyoming has no individual income tax, the SE tax is the only tax you owe on your business profit at the federal-plus-state level for this calculation (federal income tax is still separate). Wyoming has no individual income tax, so self-employment profit is subject only to the federal SE tax.

Enter your net profit below. The calculator applies the IRS net-earnings factor and the 2025 rates, shows the half you can deduct, and adds a Qualified Business Income (QBI) note.

How the 2025 federal SE tax works

  1. Net earnings = net profit × 92.35% (the 0.9235 Schedule SE factor). No SE tax is due if this is under $400.
  2. Social Security = 12.4% on net earnings up to the $176,100 2025 wage base.
  3. Medicare = 2.9% on all net earnings — no cap.
  4. Additional Medicare = 0.9% on combined wages above $200,000 (single) / $250,000 (married filing jointly).
  5. The base 12.4% + 2.9% = 15.3% combined rate is the headline figure. You may deduct one-half of the SE tax as an above-the-line adjustment on your federal return.

Worked example (Wyoming, $80,000 net profit, 2025): net earnings $73,880.00 → Social Security $9,161.12 + Medicare $2,142.52 = $11,303.64 SE tax, with $5,651.82 deductible. Wyoming state income tax on that profit: $0.

QBI deduction (separate from SE tax)

You may also qualify for the Qualified Business Income (QBI / §199A) deduction — up to 20% of your business profit — but it reduces your income tax, not your self-employment tax. For 2025 the full 20% applies without wage/property limits when taxable income (before the deduction) is at or below $197,300 (single) or $394,600 (married filing jointly).
