Michigan Retirement Income Tax 2026: 4.25% Flat Rate, $135,220 Joint Deduction, No Tax on Social Security

Michigan completed a four-year phase-in of its retirement income deduction in 2026. For the first time, all Michigan retirees — regardless of birth year — can deduct up to $67,610 (single) or $135,220 (married filing jointly) of combined retirement income from IRAs, 401(k)s, pensions, and defined contribution plans. Social Security is fully excluded from Michigan income at every income level. Military pensions are exempt with no cap. The result: a married couple with $120,000 in annual RMDs and $40,000 in Social Security pays $0 in Michigan income tax on either. Only the income above the $135,220 retirement deduction — taxed at a flat 4.25% — creates any Michigan liability. For most retirees, that is a very low number compared to high-tax states like California, New York, or Minnesota.

The deduction cap: who it matters for

For a married couple in Michigan, the $135,220 retirement income deduction is the key planning number. Here's how it plays out across different RMD levels:

Estimates assume MFJ, both spouses' personal exemptions ($5,900 × 2 = $11,800), Social Security fully excluded from Michigan income at all income levels. Retirement income = IRA/RMD withdrawals only. Other income (wages, capital gains) not included. Individual results will vary.

The takeaway: retirees with RMDs under $135,220 (MFJ) effectively owe zero Michigan income tax on their retirement income. Those above the cap owe only 4.25% on the excess — far below California's 9.3–13.3% or New York's 6.85–10.9%.

Worked examples

Example 1 — Couple at $120,000 RMD: $0 Michigan tax

At this income level, a New York couple would owe approximately $4,500 in state tax ($120K − $40K NY exclusion = $80K taxable at graduated NY rates). A California couple would owe approximately $8,400 ($120K after standard deduction through CA progressive brackets). Michigan: $0.

Example 2 — Couple at $220,000 RMD: modest Michigan tax

Compare: same New York couple owes ~$12,700 in state tax. Same California couple owes ~$16,500. Michigan: ~$3,100 — roughly 75–80% less than the two highest-profile high-tax states.

The phase-in that just completed: why 2026 is different

Before 2023, Michigan's treatment of retirement income varied sharply by birth year under a three-tier system:

• Born before 1946 (Tier 1): Public pension income unlimited exempt; private IRA income limited to $20,000 single / $40,000 MFJ.
• Born 1946–1952 (Tier 2): $20,000 single / $40,000 MFJ deduction regardless of income type.
• Born after 1952 (Tier 3): No retirement income deduction — only the Social Security exclusion and personal exemptions.

Public Act 4 of 2023 (HB 4001) replaced this system with a four-year phase-in, adding a percentage of a new, larger deduction each year. In 2026 — Year 4 — the phase-in reached 100%, and the deduction cap was set at $67,610 (single) / $135,220 (MFJ) for all birth years under Revenue Administrative Bulletin 2026-1.² The birth-year tiers no longer determine whether you get a deduction — only whether your public pension income is unlimited exempt (born before 1946) or capped.

What changed for "Tier 3" retirees (born after 1952): Before 2023, someone born in 1960 at age 67 with $180,000 in IRA withdrawals could only deduct Social Security and personal exemptions from their Michigan income — the RMD was fully taxable above those small amounts. In 2026, that same retiree deducts $67,610 (single) or $135,220 (MFJ) before any Michigan tax applies. At the $135,220 cap, Michigan tax is zero on retirement income for a married couple. It is a significant change.

QCD strategy: eliminating Michigan tax above the deduction cap

For Michigan retirees whose RMDs exceed the $135,220 MFJ deduction cap, Qualified Charitable Distributions (QCDs) are a powerful lever. QCDs reduce federal AGI dollar-for-dollar because they are excluded from gross income under IRC §408(d)(8). Michigan starts its calculation from federal income (excluding Social Security), so a QCD reduces Michigan income by the same amount.

Here's the math for a couple with $180,000 in RMDs:

The QCD eliminates Michigan state tax entirely, reduces federal taxable income, lowers the IRMAA exposure, and reduces federally taxable Social Security — all simultaneously. For Michigan retirees with large IRAs, the QCD is especially efficient because the state tax savings layer on top of the federal benefit. The 2026 QCD limit is $111,000 per person under SECURE 2.0 §307's inflation indexing.

Roth conversion timing in Michigan

Roth conversions count as retirement income for Michigan purposes and are subject to the same $67,610/$135,220 deduction cap. A conversion that puts you over the cap creates 4.25% Michigan tax on the excess. But there are two reasons Michigan can be a good state for Roth conversions:

1. Rate advantage: At 4.25%, Michigan's conversion cost is far below California (9.3%+), New York (6.85%+), or Minnesota (9.85%). If you're moving from a high-tax state to Michigan, convert after establishing Michigan residency to capture the rate differential.
2. Cap management: If your RMDs are comfortably under $135,220, you may have room to convert additional IRA funds each year up to the cap at $0 Michigan state tax cost. The conversion fills the deduction headroom with no Michigan income tax triggered.

Example: A Michigan couple taking $90,000 in RMDs has $45,220 of headroom before hitting the $135,220 cap. Converting $45,000 to Roth costs nothing in Michigan state tax while reducing future RMDs and building tax-free assets for heirs. A Roth conversion sizing calculator can help identify the federal bracket ceiling that binds first.

Michigan vs. Florida: the property tax offset

Florida is the most popular retirement destination from Michigan — no state income tax and no estate tax. But the comparison is incomplete without property taxes, which are a significant fixed cost in retirement that income-reduction strategies cannot offset.

For a couple with $120,000 in RMDs, Michigan and Florida are nearly identical in state income tax — both owe $0. The difference is $600–$2,200 per year in property taxes depending on county and home value. For those with larger RMDs ($200K+), Michigan costs roughly $2,000–$6,000 more per year in income tax, partially offset by lower cost of living, proximity to family, and lower home prices in most Michigan markets.

Social Security: no Michigan tax at any income level

Michigan is one of the majority of states that fully excludes Social Security benefits from state income — with no income means test or phase-out. Whether your combined income is $60,000 or $600,000, your Social Security benefit creates $0 Michigan state income tax. This stands in contrast to states like Minnesota (which taxes SS above $84,490/$108,320 AGI) and Connecticut (which taxes SS above $75,000/$100,000). The exclusion also means Social Security income does not push any of your RMD income over the $135,220 deduction cap — the two are independent calculations.

Michigan property tax: the homestead exemption

Michigan homeowners who use their property as their primary residence qualify for the Principal Residence Exemption (PRE), which exempts the property from the 18-mill school operating levy — typically saving $1,800–$4,000/year on a $250,000–$400,000 home. The PRE is claimed via the Michigan Department of Treasury. Additional senior property tax credits are available for households with low to moderate income through the Michigan Property Tax Credit (Form MI-1040CR).

Michigan estate tax: none

Michigan has no state estate tax or inheritance tax. The federal estate tax exemption under OBBBA is $15 million per person ($30 million combined for married couples) — effectively irrelevant for most Michigan estates. IRA assets are subject to federal income tax when inherited (under SECURE Act 10-year rule), but no Michigan state income tax applies to inherited IRA distributions for Michigan beneficiaries who qualify for the retirement income deduction on those distributions.

Planning strategies for Michigan retirees with large RMDs

• QCDs up to $111,000/person/year — eliminate Michigan tax on retirement income above the deduction cap while supporting charity. See the QCD calculator.
• Roth conversions to fill deduction headroom — if RMDs are below $135,220 MFJ, use remaining deduction space for Roth conversions with $0 Michigan state tax cost.
• Asset location — hold income-producing bonds and REITs in the IRA (forced to distribute via RMD anyway); hold growth assets in Roth or taxable accounts to reduce future RMDs. See asset location in retirement.
• IRMAA planning — reducing Michigan taxable income with QCDs or staying under the $135,220 deduction cap also reduces federal AGI, which reduces Medicare IRMAA surcharges. A double win. See IRMAA planning guide.
• Roth conversion timing for Michigan-to-Florida movers — if you plan to move to Florida eventually, do large Roth conversions after you have established Florida domicile. Converting while a Michigan resident costs 4.25% on the excess above the deduction cap; converting after the move costs $0 state tax.
