Michigan Bonus Tax Calculator

Estimate take-home pay on a bonus, using the federal flat-rate supplemental withholding method

Estimate only — not tax advice. Federal tax on the bonus uses the flat 22% supplemental withholding rate (37% on cumulative supplemental wages over $1,000,000/year) — the alternative "aggregate method" some employers use instead is not modeled. FICA and any state SDI/PFL are computed as the difference between your regular income with and without the bonus added, so the Social Security wage cap applies correctly. State tax on the bonus is a marginal-bracket estimate, not necessarily any special state supplemental rate. See methodology below for source and last-verified date.

Methodology & Source

Michigan state tax figures sourced from Michigan Department of Treasury (https://www.michigan.gov/taxes), citing MCL 206.51 — flat rate, 4.25% for 2026; personal exemption per Treasury 2026 Withholding Guide (Form 446). Federal brackets, standard deductions (single/MFJ/HoH), and FICA constants sourced from the IRS (Revenue Procedure 2025-32; married-filing-jointly Additional Medicare threshold of $250,000 is a separate, unindexed statutory figure). Michigan's married-filing-jointly and head-of-household figures have been independently verified against the source above.

Bonus federal withholding uses the flat supplemental-wage rate (22%, 37% above $1,000,000 cumulative supplemental wages/year), per IRS Publication 15 (Circular E), Employer's Tax Guide, 2026 edition — the alternative "aggregate method" is not modeled.

This is an estimate based on standard single-filer federal, FICA, and MI state calculations. Actual withholding may differ based on your W-4 elections, pre-tax deductions, local city tax, and other factors.
