You just sold your lake house in Traverse City or maybe some stock that finally took off. Congrats. But now, you're staring at the tax bill and wondering how much the State of Michigan wants to claw back. Most people get a bit of a shock because they focus entirely on the federal IRS rates—those 15% or 20% numbers—and completely forget that Lansing wants a seat at the table too.
The good news? Michigan is actually one of the simpler states to deal with when it comes to capital gains tax Michigan. It doesn't have a separate, tiered system for capital gains like the federal government does. Instead, Michigan treats your "profit" basically like your "paycheck."
The Flat Rate Reality in the Mitten State
In Michigan, there is no special "capital gains rate." Whether you made money selling a rare comic book or flipping a condo in Grand Rapids, the state taxes that income at the standard individual income tax rate.
For the 2024 and 2025 tax years, that rate is 4.25%.
It’s a flat tax. Simple. But there's a catch that catches people off guard. Back in 2023, the rate actually dipped to 4.05% because of a 2015 law that triggers a tax cut if the state's general fund grows faster than inflation. However, Attorney General Dana Nessel and the state Treasury clarified that this dip was temporary. So, if you’re calculating your 2024 or 2025 liability, stick with the 4.25% figure. If you’re looking at your 2023 returns in the rearview mirror, you might have caught that lower 4.05% break.
Wait. Don't forget the feds.
When you calculate your total burden, you're layering that 4.25% on top of the federal long-term rates (0%, 15%, or 20%) or your federal ordinary income brackets if it’s a short-term gain. If you’re in a high-income bracket, you could easily be looking at a total "haircut" of nearly 25% on your profits. That hurts.
Federal Adjusted Gross Income: The Starting Line
Michigan is what tax nerds call a "rolling conformity" state. Essentially, the Michigan 1040 starts with your Federal Adjusted Gross Income (AGI).
If you reported a capital gain on your federal Form 1040 (specifically on Schedule D), it’s already baked into your Michigan AGI. You don't usually have to add it back or do weird math. If the IRS sees it, Michigan sees it. This means the definitions for "long-term" (assets held for more than a year) and "short-term" (held for a year or less) matter for your federal filing, but they don't change the rate Michigan charges you.

Lansing treats a $10,000 short-term gain exactly like a $10,000 long-term gain. 4.25% is 4.25%.
The Principal Residence Exemption (PRE)
Selling your home? This is where you breathe a sigh of relief. Michigan follows the federal lead on the primary residence exclusion.
Under Internal Revenue Code Section 121, if you’ve owned and lived in your home for at least two of the five years before the sale, you can exclude up to **$250,000** of the gain from your income ($500,000 for married couples). Since this gain is excluded from your federal AGI, it never even touches your Michigan tax return. It’s "ghost money"—it exists in your bank account, but it doesn't exist for the tax man.
But watch out for the "non-qualified use" rules. If you rented the house out for three years and then lived in it for two, the math gets messy. You can’t exclude the portion of the gain that occurred while it was a rental.
What About Losses?
Markets go down. Sometimes you lose your shirt on a bad investment.
Michigan allows you to deduct capital losses, but only to the extent they are deducted on your federal return. Usually, this means you can use your losses to offset your gains. If your losses exceed your gains, you can use up to $3,000 of that excess loss to reduce your other taxable income (like your salary).
If you have a $50,000 loss, you can’t dump it all at once. You take the $3,000 hit this year and carry the rest forward to future years. Michigan stays in lockstep with the federal carryover rules. It’s a long game.
The "Secret" 100% Tax Break: Michigan Dividend/Interest/Capital Gains Deduction
Here is something almost nobody talks about unless they have a really good CPA. Michigan has a specific deduction for seniors.

If you were born before 1946, you might be eligible to deduct a significant portion of your dividend, interest, and capital gains income. For the 2024 tax year, the deduction can be as high as $13,912 (single) or $27,824 (joint).
However, if you were born after 1946, the rules changed significantly during the Snyder and Whitmer administrations. The "Pension Tax" repeal recently signed by Governor Whitmer primarily targets retirement distributions and pensions, but it hasn't completely restored the old-school "senior" deduction for investment income for younger Boomers and Gen X.
Real Estate and the "Step-Up" in Basis
Let’s talk about inheritance. This is a huge part of capital gains tax Michigan conversations.
If you inherit a cottage in Muskegon that your parents bought in 1970 for $20,000, and it’s now worth $400,000, you get what’s called a "step-up in basis." Your "cost" for tax purposes becomes $400,000 the day they pass away. If you sell it a month later for $400,000, your capital gain is zero.
Zero gain = Zero Michigan tax.
If you’re thinking about "adding your kids to the deed" while you’re still alive—stop. Talk to a pro first. If you give them the house now, they inherit your 1970 basis of $20,000. When they sell it after you're gone, they’ll owe Michigan 4.25% on that $380,000 spread. That’s a $16,150 mistake that could have been avoided by just letting the property pass through a will or trust.
Why 2026 and Beyond Might Look Different
Tax laws are about as stable as a Michigan winter. While the current flat rate is the law of the land, there are always rumblings in the legislature about "graduated" income taxes.
In 2022, a ballot initiative to create a graduated income tax failed, but the conversation persists. If Michigan ever moved to a system where higher earners pay a higher percentage, your capital gains would likely be swept into those higher tiers. For now, enjoy the predictability of the 4.25%.

Common Misconceptions That Cost Money
People often think that if they "reinvest" the money—like buying a different stock immediately—they don't have to pay the tax.
Nope.
Unless you are doing a 1031 Exchange for an investment real estate property, "selling" is a taxable event. The moment you click sell on that E-Trade account, the clock starts ticking for the Michigan Department of Treasury. You can't just buy a different stock and pretend the profit didn't happen.
Another one? "I paid sales tax, so I don't owe capital gains."
Sales tax is for the purchase of goods. Capital gains tax is for the profit on the sale of an asset. They are completely different animals.
Actionable Steps for Your Michigan Gains
If you're sitting on a massive gain, don't just wait for April 15th to roll around.
- Calculate the "True" Basis: Did you renovate that house? Keep the receipts for the new roof and the kitchen remodel. These costs increase your basis and lower your taxable gain. In Michigan, every $1,000 you add to your basis saves you $42.50 in state tax.
- Harvest Your Losses: If it's December and you have a big gain from a stock sale, look through your portfolio for "losers." Selling them now can offset your gains and lower your Michigan AGI.
- Check Your Estimated Payments: Michigan requires you to pay taxes as you earn the income. If your capital gain is huge, and you don't pay an estimated tax payment to the state in the quarter the sale happened, Lansing might hit you with an underpayment penalty.
- Residency Matters: If you move to Florida in November and sell your stock in December, you might avoid the 4.25% Michigan tax. But be careful—Michigan is aggressive about "domicile" audits. If you still have a Michigan driver's license and a library card, they might claim you're still a resident.
The Michigan Department of Treasury's Official Site is actually surprisingly helpful for looking up the current year's forms and instructions. Most of what you need is on the MI-1040 and the Schedule 1.
Honestly, the state tax is rarely the "deal breaker" in a sale. It’s the federal tax that does the heavy lifting. But 4.25% of a $500,000 business sale is $21,250. That’s a brand-new car or a lot of trips to Mackinac Island. Plan for it.
Next Steps for Accuracy
Review your most recent Federal Schedule D to see your total taxable gains. Multiply that number by 0.0425 to get a ballpark of what you'll owe the state. If that number is over $500, it's time to look at making an estimated payment via the Michigan Treasury Online (MTO) portal to avoid late-payment interest. Don't let the simplicity of a flat tax lull you into a penalty.
