## Outputs

| Key | Label | Description |

## Assumptions

- An estimate for a full-year resident, 2026 rates, not tax advice.
- Starts from federal AGI; Michigan additions and subtractions are not modelled.
- Not modelled for Michigan: City income taxes (Detroit and others) are typed by the user. No itemized deductions: MI-1040 subtracts only exemptions and Schedule 1 items from AGI (2025 MI-1040 instructions).
- Not modelled: part-year and nonresident returns, other state credits, and state AMT.
