Retirement Taxes in Michigan: What Nobody Tells You Until It's Too Late
Key Takeaways
Retirement doesn't lower your tax bill. It changes the source of it. Michigan's new exemptions are real progress, but the federal picture, RMDs, investment income, and withdrawal timing still create serious complexity for anyone who has actually built wealth.
Starting in 2026, Michigan's four-year phase-in is complete. All eligible retirees can now deduct 100% of qualifying retirement income from state taxes regardless of birth year, up to $67,610 for single filers and $135,220 for married filing jointly.
The most expensive retirement tax mistakes aren't about strategy. They're about coordination. Roth conversions, RMDs, Social Security, a business sale looked at individually, each decision might be fine. Done in the same year without a plan, they can create a higher than average tax bill.
Most people spend decades doing everything right.
Saving aggressively. Maxing out retirement accounts. Building portfolios. Accumulating company stock. Growing businesses. Being responsible.
Then retirement gets close and everything they thought they understood about taxes starts to shift.
Which accounts do I pull from first? What happens when required minimum distributions kick in? Should I be doing Roth conversions? When do I sell concentrated stock positions? How much of this will Michigan actually tax?
And then the question that genuinely catches people off guard:
Why is my tax bill still this high?
I've worked with successful professionals who walked into retirement fully expecting their taxes to drop dramatically once their salary stopped. They had done everything right. Saved diligently for decades. Built real wealth. What they hadn't planned for was that all that wealth sitting inside tax-deferred accounts, appreciated brokerage positions, employer stock, real estate, business interests doesn't stop creating tax complexity just because you stopped working.
Retirement shifts your tax problem. It doesn't eliminate it.
Chasing a zero tax bill isn't realistic, and the strategies promising it tend to create more problems than they solve. The real goal is flexibility, fewer preventable mistakes, and keeping more of what you spent your career building. In Michigan, that's genuinely achievable, but it requires planning that starts earlier than most people expect and covers more ground than a single conversation with your CPA in March.
Does Michigan Tax Social Security Benefits?
Michigan does not tax Social Security benefits. That's meaningful, and it's one of the reasons Michigan is more retirement-friendly than people assume.
But stopping there is a mistake. At the federal level, depending on your total income, up to 85% of your Social Security benefits can still become taxable. IRA withdrawals, pension income, investment income, capital gains, rental income: all of it feeds into the federal calculation. Which means Social Security timing isn't a standalone decision. It interacts with every other income source in your retirement picture, and getting it wrong has a long tail.
Michigan Retirement and Pension Income Tax Rules
A lot of the information floating around online about Michigan retirement taxes is outdated. Here's what's actually true for 2026.
Under the Lowering MI Costs Act (Public Act 4 of 2023), Michigan spent four years gradually restoring retirement income exemptions that were cut back in 2011. That phase-in is now complete. Starting with the 2026 tax year, all eligible Michigan retirees can deduct 100% of their combined public and private retirement and pension income from state taxes, regardless of birth year. The birth year tier system (Tier 1, Tier 2, Tier 3) is fully phased out.
The 2026 exemption caps are $67,610 for single filers and $135,220 for married filing jointly. Military pensions are fully exempt with no cap. Public safety retirees (police, firefighters, corrections officers) can claim an unlimited exemption on public pension income.
Public Act 24 of 2025 added another change worth knowing about. Michigan taxpayers born after 1952 and aged 67 or older can now claim both the standard deduction and the Social Security deduction simultaneously for tax years 2026 through 2028. Previously, qualifying retirees had to reduce their standard deduction by whatever amount they claimed for Social Security, effectively canceling part of one benefit to use the other. That's gone for these three tax years. The standard deduction is still reduced by the personal exemption amount, so it's not unlimited, but the Social Security piece no longer eats into it.
Michigan is becoming more favorable for retirees, not less. That's the genuinely good news.
Even so, the federal picture, investment income, and withdrawal sequencing still create real complexity for anyone who has built meaningful wealth. If you have a pension, the rules around public versus private pensions, military retirement, and railroad retirement benefits add another layer that depends on your specific situation, not just your birth year.
One thing that gets missed constantly: SSA exempt employment. SSA exempt means the worker didn't pay Social Security taxes and isn't eligible for Social Security benefits based on that job. Police and firefighter retirees, some state and local government workers, and federal employees covered under the Civil Service Retirement System hired before 1984 are the most common examples. If you or your spouse worked in SSA exempt employment, you may qualify for an increased retirement and pension deduction of up to $15,000 per eligible taxpayer, but the eligibility criteria are specific and worth verifying with your CPA rather than assuming you qualify or don't. Missing this can mean leaving thousands in deductions on the table every single year.
How Tax-Deferred Accounts Create Retirement Tax Problems
For decades, the advice was consistent: maximize pre-tax 401(k) contributions, defer taxes, reduce current taxable income. Good advice during peak earning years. The right move in many situations.
The problem is that following it faithfully for 30 years can build a serious tax concentration problem nobody warned you about.
When most of your wealth sits in traditional IRAs, 401(k)s, and rollover accounts, you have far less control over your tax situation in retirement than you think. Large withdrawals create ordinary income. Required minimum distributions force withdrawals whether you want the money or not, and they don't care what else is happening in your financial life that year. Stack those on top of Social Security, pension income, investment income, and real estate income and suddenly the tax bill looks nothing like what you projected.
Retirement planning has to include tax diversification, not just asset growth. Flexibility across account types means you get to have some say in what your income picture looks like year to year, rather than letting the IRS dictate it through RMD rules. If most of your wealth is sitting in pre-tax accounts right now, that's worth understanding before you retire, not after.
Roth Conversions in Retirement: When They Make Sense
Qualified withdrawals from Roth IRAs and Roth 401(k)s are tax-free at both the federal and Michigan level. In the right year, that matters enormously.
Lower-income windows are when conversions make the most sense: career transitions, early retirement years before Social Security starts, temporary income dips. The tax cost of converting is lower, and the long-term benefit of tax-free growth is higher.
I converted my own IRA during my first year running my own firm. My income was significantly lower than it had been in previous years, and I knew immediately it was the right window. I ran the numbers, prepared for the tax cost on both the federal and Michigan side in advance, had the cash set aside for estimated taxes, and didn't hesitate. I still feel good about it.
A pattern I see with clients approaching retirement: someone leaves work at 62 and has a gap before Social Security starts and before RMDs kick in. That window, sometimes three to five years, is genuinely valuable. Converting a meaningful portion of pre-tax assets to Roth during that period means paying tax at a lower rate than they did during peak earning years, and a lower rate than they'll face once RMDs and Social Security stack up together. Not everyone has that window. But identifying it early enough to use it is exactly what proactive planning is for.
How Capital Gains Taxes Work in Retirement
Brokerage accounts are often a retiree's most flexible asset. No RMD rules. Not locked up. Useful for supplementing income in a tax-efficient way when managed thoughtfully.
The problem is that capital gains exposure is routinely underestimated, especially by people who've held appreciated positions for a long time.
Michigan taxes capital gains as ordinary income at the state's flat 4.25% rate, confirmed by the State Treasurer's office for 2026. Residents born before 1946 may be eligible for an investment income subtraction, though the annual dollar limit is reduced by any retirement benefit subtraction already claimed that year. At the federal level, selling appreciated assets can trigger capital gains taxes, net investment income tax exposure, higher Medicare premiums, and increased Social Security taxability, sometimes all at once.
This is especially relevant with concentrated company stock, highly appreciated positions, inherited investments, real estate, or business interests.
And the emotional piece is real. I work with equity compensation clients regularly and the pattern is consistent. They understand intellectually that a concentrated position is a risk. They know the argument for diversifying. They can make it themselves. And they still can't bring themselves to sell because the stock represents something. Years of work. A company they believed in. An identity. Selling feels like losing something even when it's the right call. That's not irrational. It's human. And financial decisions don't happen in a vacuum. The psychology is as real as the math, sometimes more so.
Michigan Property Taxes and Retirement Planning
Most retirement tax conversations never get to property taxes. They stay focused on income, retirement accounts, and investments while housing decisions get treated as purely lifestyle choices.
That's a mistake.
Michigan property tax rates vary significantly by location. Local millage rates, primary residence exemptions, second homes and vacation properties all affect the real number. Downsizing, relocating, buying that lake house: these decisions carry tax implications that deserve real analysis, not just a gut check on whether you can afford the mortgage. The lifestyle math and the financial math don't always point the same direction, and both deserve attention before you sign anything. If you're considering a move in retirement, running the property tax numbers before you commit is worth the hour it takes.
What Is IRMAA and How Does It Affect Retirement Income?
Most people don't find out Medicare premiums can increase based on income until the bill arrives.
IRMAA (Income-Related Monthly Adjustment Amount) is a federal surcharge set by the Centers for Medicare & Medicaid Services. It applies equally in Michigan and everywhere else. When your Modified Adjusted Gross Income crosses certain thresholds, your Medicare Part B and Part D premiums go up, sometimes by hundreds of dollars per month.
The 2026 IRMAA thresholds are based on your 2024 MAGI. That two-year lookback is the part that catches people off guard: a large income event in 2024 affects Medicare costs in 2026, not immediately. For single filers with 2024 MAGI of $109,000 or less (married filing jointly at $218,000 or less), the standard Part B premium is $202.90 per month with no Part D surcharge. At the highest tier, single filers with MAGI over $500,000 pay $689.90 per month for Part B plus $91.00 monthly for Part D.
The cliff effect is what makes this genuinely dangerous in planning. One dollar over a bracket threshold triggers the full surcharge for that entire tier. A Roth conversion that pushes MAGI $5,000 over a cutoff can add thousands of dollars in Medicare costs for the year, not because the conversion was wrong, but because nobody modeled the Medicare impact before pulling the trigger. For a married couple, crossing from Tier 1 to Tier 2 alone costs an additional $3,475 per year in Medicare premiums. That recurs every year your income stays above the line.
If you experienced a qualifying life event (retirement, divorce, death of a spouse), you can appeal your IRMAA determination using Form SSA-44 with the Social Security Administration. That option exists, it works, and most people have never heard of it.
Something that almost never gets planned for: what happens to Medicare costs when a spouse dies. When a surviving spouse files as Single, the IRMAA brackets are roughly half the married filing jointly thresholds. A couple comfortably in Tier 1 as joint filers can land two tiers higher as a single filer with no actual change in income. For a surviving spouse, who is statistically more likely to be a woman, that's thousands of dollars more per year in Medicare costs at exactly the moment when financial life is already hard. Planning for this scenario before it happens is worth the conversation. The best defense is building Roth assets while both spouses are alive, so the surviving spouse has tax-free income that doesn't push Medicare costs higher.
One more thing: qualified Roth IRA distributions don't count toward MAGI for IRMAA purposes. Traditional IRA distributions do. Building Roth assets before retirement isn't just about tax-free growth. It's also about managing Medicare costs for the rest of your life.
Retirement Income Spikes: The Tax Mistake That's Entirely Avoidable
This one creates the most damage, and it happens to smart people all the time.
In a single year: sell a business, sell real estate, take a large IRA withdrawal, complete a Roth conversion, sell a concentrated stock position, start Social Security. Each decision, looked at alone, might be entirely defensible. Together, they create an enormous and entirely avoidable tax year.
Not because any individual decision was wrong. Because none of them were looked at together.
Spreading decisions across multiple years, sequencing withdrawals intentionally, looking at the full income picture before making any single move: that's where the real value of coordinated planning shows up. The order in which you draw from different account types (taxable brokerage, traditional IRA, Roth) has a meaningful impact on your lifetime tax burden. The right sequence depends on your income sources, projected RMDs, Social Security timing, and what you're trying to accomplish with what remains. There's no universal answer, which is exactly the point.
The Emotional Side of Retirement Tax Planning
You've spent decades building. Saving. Making the responsible choice, often at the expense of enjoying the present, because your future self deserved protection.
Then retirement arrives and asks you to do the opposite. Spend. Withdraw. Restructure everything you spent years carefully building. For people whose financial identity is built around accumulation and discipline, that shift is genuinely uncomfortable, even when the numbers are fine. I've worked with clients who had more than enough, knew they had more than enough, and still couldn't give themselves permission to use it.
I see this most with women who spent decades managing financial complexity for everyone around them: their households, their families, sometimes their businesses, while quietly putting their own needs last. The work in retirement isn't just technical. It's also about giving yourself permission to actually benefit from what you built. And sometimes you need that permission from someone other than yourself.
If the emotional side of retirement resonates, I wrote more about what that transition actually looks like.
What Retirement Tax Planning Actually Involves
The retirees who come out ahead aren't the ones who found the best tax hack. They're the ones who stopped treating taxes as a once-a-year event and started making coordinated decisions across years.
Withdrawal sequencing, Roth conversion analysis, Social Security timing, concentrated stock planning, charitable giving strategies, estate planning, healthcare cost planning, multi-year income projections: not all at once, but as part of a plan that actually adjusts as your life changes.
Michigan is a reasonable state for retirees, and it's getting better. But state tax treatment doesn't replace the need for coordination. Strong retirement outcomes come from intentional decisions made over time, not a single conversation in March after the window has already closed.

-
No. Michigan does not tax Social Security benefits at the state level. However, depending on your total income, up to 85% of your Social Security benefits can still become taxable at the federal level. IRA withdrawals, pension income, capital gains, and investment income all feed into that federal calculation, which is why Social Security timing decisions have to be evaluated alongside the rest of your retirement income picture, not in isolation.
-
IRMAA stands for Income-Related Monthly Adjustment Amount, a federal Medicare surcharge that applies when your Modified Adjusted Gross Income exceeds certain thresholds. For 2026, the surcharge kicks in at $109,000 MAGI for single filers and $218,000 for married couples filing jointly, based on your 2024 tax return. The surcharges apply equally in Michigan and every other state. Earning even $1 over a bracket threshold triggers the full surcharge for that tier, which can add thousands of dollars per year to Medicare costs. Roth conversions, business sales, and large IRA distributions are the most common triggers.
-
For many Michigan retirees, Roth conversions during lower-income years including career transitions, early retirement before Social Security starts, or temporary income dips may create long-term tax and Medicare savings. Qualified Roth distributions don't count toward MAGI for IRMAA purposes, which means building Roth assets reduces both future tax exposure and Medicare premium costs. The right conversion amount depends on your specific income sources, projected RMDs, IRMAA bracket position, and Social Security timing.

Michigan is more retirement-friendly than most people realize, and it's getting better. Starting in 2026, all eligible Michigan retirees can deduct 100% of qualifying retirement and pension income from state taxes regardless of birth year, up to $67,610 for single filers and $135,220 for married filing jointly. Michigan does not tax Social Security benefits, military pensions are fully exempt, and the state's flat income tax rate remains at 4.25% for 2026.
That said, favorable state tax treatment doesn't eliminate federal tax complexity. RMDs, capital gains, IRMAA, and withdrawal sequencing still require planning for anyone who has built significant wealth.
