Michigan income tax calculator 2026 – how it works
This Michigan income tax calculator estimates Michigan state income tax using the current flat tax rate under published Michigan tax rules. Michigan uses a flat state income tax system. Under the current published Michigan tax rules, the individual income tax rate is 4.25 percent. The calculation starts with Michigan-taxable income and applies the flat tax rate after subtracting the applicable personal exemption amount. Michigan does not use a federal-style standard deduction. Instead, each qualifying exemption reduces taxable income by a fixed amount before the tax rate is applied.
Examples
Example 1: A single filer with $60,000 in Michigan-taxable income applies the personal exemption first, then the 4.25 percent flat tax rate to the remaining taxable amount. Example 2: A household with dependents applies multiple personal exemptions, reducing the taxable base before the flat tax rate is applied. Example 3: Increasing income does not change the tax rate. Michigan income tax increases proportionally because the same rate applies at all income levels.
