Three states have their own calculator, because the state rate alone would be wrong: Maryland (every county adds a local rate) · Indiana (all 92 counties charge one) · New York (a recapture applies above $107,650)
S-Corp vs LLC Tax Calculator
A sole trader pays employment tax on all of the profit. An S-corp pays it only on the salary, and the rest comes out as a distribution. This compares the two on the salary you choose — and shows where the saving stops.
Prepared for the 2026 tax year.
The rules for the 2026 tax year are published during 2025 and 2026 — the adjusted figures first, the explaining publications as the year goes on — and the return they govern is filed in 2027.

How each side is worked out
What comes next? The salary you set decides more than your payroll tax. It also caps what you can put into retirement on the corporate side. The SEP IRA Contribution Calculator gives the maximum contribution on that salary, and the rate the IRS actually applies.
