Michigan made a significant change to how it taxes retirement income under Public Act 4 of 2023 — a phased restoration of retirement income deductions that reaches full effect in tax year 2026. For most Michigan retirees, this means the deduction now exceeds their total retirement income, effectively eliminating state tax on pension, 401k, and IRA withdrawals.
The 2026 deduction amounts are $65,987 for single filers and $131,794 for married couples filing jointly. Combined with Michigan's complete exemption of Social Security income, the state has moved from one of the more burdensome retirement tax states to one of the most competitive in the Midwest. This guide explains exactly how the new rules work, who qualifies, and what the tax savings look like in practice.
Before Public Act 4 of 2023, Michigan had gradually reduced retirement income deductions, making it increasingly expensive for retirees to remain in the state. The 2023 law reversed that trend by restoring and phasing in retirement income deductions tied to birth year cohorts.
Michigan Governor Gretchen Whitmer signed the act into law in February 2023. The phase-in was structured so that all birth year cohorts reach full deduction entitlement by tax year 2026. For the 2026 tax year (filed in April 2027), every Michigan retiree regardless of birth year can claim the full deduction amounts.
Michigan's income tax rate was also reduced from 4.25% to 4.05% as part of the same legislative session (triggered by a revenue-based automatic reduction mechanism under existing law).
The 2026 retirement income deduction amounts are:
| Filing Status | 2026 Deduction | Tax saved (at 4.05%) |
|---|---|---|
| Single / Married Filing Separately | $65,987 | ~$2,673 |
| Married Filing Jointly | $131,794 | ~$5,338 |
These amounts are set by reference to the maximum Social Security benefit at Full Retirement Age — the same methodology used by Maine and several other states. The figures are adjusted periodically.
For a married couple with $120,000 in combined pension and IRA income, the $131,794 MFJ deduction fully covers their retirement income, resulting in $0 Michigan state tax on that income. Michigan state tax would only apply to income above the deduction threshold.
Important: Public safety retirees (police, fire, corrections) face no cap on the deduction — all retirement income is exempt regardless of amount.
Public Act 4 of 2023 used a birth-year-based phase-in to implement the deductions over three tax years:
| Birth Year | 2023 | 2024 | 2025 | 2026 |
|---|---|---|---|---|
| 1945 or earlier | Full deduction | Full deduction | Full deduction | Full deduction |
| 1946–1952 | 25% of deduction | 50% of deduction | 75% of deduction | Full deduction |
| 1953 and later | 25% of deduction | 50% of deduction | 75% of deduction | Full deduction |
By tax year 2026, every retiree regardless of birth year receives the full deduction. The phase-in is now complete.
The retirement income deduction applies to most common retirement income sources but has one notable exclusion that catches some Michigan retirees off guard:
Social Security is exempt by separate provision and does not consume any of the retirement income deduction — you get both.
These examples assume a single filer in 2026 with all qualifying retirement income (pension + IRA), Social Security exempt separately:
| Retirement Income | Deduction | Michigan Taxable | Michigan Tax (4.05%) |
|---|---|---|---|
| $60,000 | $65,987 | $0 | $0 |
| $80,000 | $65,987 | $14,013 | ~$568 |
| $100,000 | $65,987 | $34,013 | ~$1,378 |
| $150,000 | $65,987 | $84,013 | ~$3,403 |
For a married couple (MFJ) with $130,000 combined retirement income: the $131,794 MFJ deduction covers the entire amount → $0 Michigan state tax.
For a married couple with $200,000: Michigan taxable = $200,000 − $131,794 = $68,206 → Michigan tax ≈ $2,762.
The three largest Midwestern states — Michigan, Ohio, and Illinois — each handle retirement income taxation differently:
| Factor | Michigan | Ohio | Illinois |
|---|---|---|---|
| Income tax rate | 4.05% flat | Graduated 2.75%–3.5% | 4.95% flat |
| Pension/IRA tax | $65,987/$131,794 deduction | Retirement income credit available; pensions taxed above credit | Fully exempt all ages |
| Social Security | Fully exempt | Partially exempt (income-based credit) | Fully exempt |
| Estate tax | None | None | None |
| Property tax (avg) | ~1.32% | ~1.36% | ~2.08% |
Illinois offers full exemption for all pension and IRA income regardless of amount — making it better for very high retirement incomes. Michigan's deduction-based system is effectively equivalent for retirees with up to $65,987 (single) or $131,794 (joint) in retirement income, which covers the majority of Michigan retirees.
Michigan has moved from being one of the more retirement-unfriendly Midwestern states to one that now rivals Illinois for middle-income retirees. The combination of:
...makes Michigan competitive for retirees with retirement incomes below the deduction threshold. For retirees with higher incomes ($200k+), states with zero income tax (Florida, Texas) or full pension exemptions (Illinois) remain more attractive.
