BONUS CALCULATOR / MICHIGAN

Michigan
bonus tax calculator.

Separate Michigan bonus withholding from federal deductions and the city amount supplied by payroll.

Your bonus payment

Prior wages are before this regular paycheck and bonus. Supplemental wages include common-control employers. Assumes W-4 Step 2 unchecked, zero adjustments and no benefit deductions. If those assumptions do not match, use your payroll provider.

Michigan bonus treatment

Separately paid Michigan bonus: 4.25% state withholding, without regular-pay allowances. City withholding needs confirmation.

Enter only deductions attributable to this bonus, not the entire regular paycheck. No pretax benefit changes, state exemptions, or cross-state wages are supported.

State treatment of this bonus

Michigan separately paid employee bonuses use 4.25% withholding without regular-pay exemptions. A $1,000 bonus produces $42.50 state withholding. A city may also withhold income tax.

A worked bonus example

A $1,000 bonus with federal flat withholding of $220, incremental FICA of $76.50 and Michigan withholding of $42.50 leaves $661 before city and other deductions. Confirming a $5 city amount changes the estimate to $656.

When this estimate does not apply

A missing city confirmation leaves the result partial. Do not reuse a regular-pay city amount unless payroll confirms it also applies to this bonus.

Regular resident W-2 wages, separately paid cash bonus after the entered regular wages, in the same payroll period only. A bonus paid before those regular wages is not supported. No benefit changes, state exemptions, stock awards, gross-up, or earlier supplemental payment in that period. Federal assumptions are shown in the form. Withholding is a payment toward tax, not the final tax bill.
