How Much Are Bonuses Taxed in Michigan in 2025?

Bonuses in Michigan get taxed at two levels. You pay federal taxes and state taxes on them.

Federal tax rate on bonuses: Your employer takes out 22% for federal taxes. But if your bonus is over $1 million, they take out 37% instead.

Michigan state tax rate on bonuses: Your employer takes out 4.25% for Michigan state taxes. This is the same rate for all bonus amounts.

Payroll taxes also apply: You’ll pay Social Security tax (6.2%) and Medicare tax (1.45%) on your bonus too.

How Employers Calculate Your Bonus Taxes

Your employer can use two methods to figure out your bonus taxes:

Percentage method: They give you a separate bonus check. They take out the flat rates we mentioned above.

Aggregate method: They add your bonus to your regular paycheck. Then they calculate taxes based on your total pay for that period.

Real Example: $1,000 Bonus Tax Breakdown

Let’s say you get a $1,000 bonus in Michigan:

  • Federal tax withheld: $220 (22%)
  • Michigan state tax withheld: $42.50 (4.25%)
  • Social Security tax: $62 (6.2%)
  • Medicare tax: $14.50 (1.45%)
