How Michigan Income Tax Works
Michigan uses a flat-rate tax system: every taxpayer pays the same percentage (4.25%) of their taxable income, regardless of how much they earn. The state calculates your taxable income by subtracting the standard deduction (or itemized deductions) from your gross income, then multiplies by 4.25%.
When you earn income in Michigan, your employer withholds both federal income tax (sent to the IRS) and MI state tax (sent to the Michigan Department of Revenue). At tax time, you file two separate returns: one federal (Form 1040) and one MI state return.
You can file Michigan state taxes through tax software (TurboTax, H&R Block, FreeTaxUSA), hire a local accountant, or file directly with the Michigan Department of Revenue. Most MI state returns are due April 15, the same as federal. Some states offer a 6-month extension (to October 15) if you also extend your federal return.
Example: Michigan Tax on $75,000
A single Michigan resident earning $75,000 in 2026 would pay approximately:
- Federal tax: ~$10,500 (24% marginal bracket, after deductions)
- MI state tax: $2,567 (calculated using the brackets above)
- FICA (Social Security + Medicare): $5,738 (7.65% on first $168,600)
- Total annual tax burden: ~$18,805
- Effective tax rate: 25.1% (combined federal + MI state)
