Winning money at a Michigan casino, sportsbook, or via a lottery ticket feels thrilling, but it comes with tax strings attached. All gambling and lottery winnings in Michigan are taxable at both the state and federal level. Whether you pocket a few hundred bucks or hit a massive jackpot, you’ve got to report those winnings when you file taxes.
Michigan takes a flat 4.25% cut for state tax, and the feds may grab up to 24%, depending on your win and the type of game. Sometimes, taxes get withheld automatically; other times, it’s on you to report. Knowing the basics helps you avoid headaches and keeps you on the right side of the law. If you want more details, the Michigan Department of Treasury has plenty of info and forms.
Which forms you need, what to do about losses, and how to handle things if you don’t get a tax form – these are the details that can make tax season less stressful. Here’s a breakdown of the essentials so you know what’s coming when it’s time to file.
Michigan treats gambling and lottery winnings as income you have to report on your state return, and usually, they’re also taxed federally. The nitty-gritty depends on the type of gambling, your residency, and whether taxes got withheld when you got paid.
In Michigan, gambling income isn’t just casino jackpots. It’s lotteries, raffles, sports betting, DFS, poker, bingo, slot machines – really, any kind of prize, even non-cash ones like cars or trips, counts and needs reporting at fair market value.
Online sportsbook and casino wins are taxed just like in-person prizes. If you gamble with licensed Michigan operators, the state expects its share.
You can’t just subtract your losses from your winnings unless you itemize deductions on your federal return, and even then, you can only offset up to the amount you won. For Michigan, you have to report your full gambling income before thinking about any deductions.
The IRS wants you to report all gambling winnings as part of your gross income, no matter how much you won. You might get a Form W-2G if you clear certain thresholds, but even if you don’t, you’re still responsible for reporting everything.
Michigan taxes gambling winnings included in your federal adjusted gross income. If the IRS taxes it, Michigan does too. The state won’t let you net out winnings and losses unless you qualify for federal itemized deductions.
Michigan does let you exclude the first $300 of gambling, bingo, or prize winnings from total household resources for some credits, but that doesn’t reduce your taxable income. You can check Michigan income tax forms and info for more on credits and rules.
Michigan residents have to report all gambling income, no matter where you won it – Vegas, Ontario, or a random online platform, it’s all fair game for Michigan taxes.
Nonresidents only pay Michigan tax on winnings from bets placed within the state. So, if you win at a Detroit casino or with a Michigan-licensed sportsbook, Michigan wants its cut.
If you’re a nonresident, you can only deduct losses up to your Michigan winnings, and only if those bets were placed at licensed Michigan casinos or racetracks.
Casinos, sportsbooks, and lotteries sometimes withhold taxes from big wins. The feds usually take 24%, and Michigan grabs 4.25%. You’ll see this on your W-2G, and it counts toward your tax bill.
Smaller wins usually don’t get withheld, but you still have to report and pay tax on them. If you win big and nobody withheld taxes, you might need to make estimated tax payments during the year to dodge penalties. You can find payment instructions and forms at the Michigan estimated tax page.
Yep, gambling winnings get taxed at both the state and federal level. You have to report Michigan gambling winnings on your income tax return, and the IRS expects to see them on your federal return too. Doesn’t matter what game, how you’re paid, or where you live – the rules are the same.
Absolutely. Michigan taxes any gambling winnings that show up in your federal adjusted gross income. This covers casinos, lotteries, sports betting, poker, horse racing – you name it.
If you’re a nonresident, you still owe Michigan income tax on gambling winnings earned here. Reciprocal agreements with other states don’t apply to gambling income.
Michigan doesn’t let you subtract gambling losses on your state return. You can only offset winnings with losses if you itemize on your federal return, and only up to the amount you won.
All winnings count, even small slot or lottery payouts. There’s no minimum threshold for reporting.
Nope. Michigan just treats gambling winnings as regular income, taxed at the state’s flat rate.
Detroit casinos and sportsbooks pay their own wagering taxes, but that’s not your problem as a player. You just need to report your winnings on your MI-1040 and pay your state income tax.
For example:
So, whether you win $200 on a scratch-off or $20,000 at a poker table, your tax responsibility is the same.
Casinos, sportsbooks, and lotteries send you a Form W-2G if you cross certain win thresholds. Here’s when you’ll see one:
You might also get a Form 1099-MISC for non-cash or promo prizes.
Even if you never get a W-2G or 1099, you still have to report all your Michigan gambling winnings. The Michigan Department of Treasury can match your return to federal records and casino reports, so fudging the numbers isn’t worth the risk.
Yes, they are. If you win crypto gambling, you have to report the fair market value of the coins at payout. The IRS treats crypto as property, and Michigan follows the federal lead for tax purposes.
Say you win 0.05 BTC in a poker game and it’s worth $1,500 at the time – you need to report $1,500 as income. Later gains or losses when you sell or trade the crypto are a separate issue from your gambling income.
Promo credits or free play from casinos aren’t taxable when you get them, but if you use them to win real money, those winnings are taxable. This includes online sports betting bonuses and free spins at Michigan-regulated casinos.
Keep good records of your crypto transactions, bonus use, and winnings to make tax time easier.
When you win gambling or lottery money in Michigan, both state and federal taxes kick in. What you owe depends on where you live, how much you won, and whether you took a lump sum or annuity. Sometimes, taxes get withheld automatically; other times, you have to report yourself.
Michigan taxes gambling and lottery winnings at a flat 4.25% individual income tax rate. This applies to residents and nonresidents who win in the state.
You need to report all winnings as taxable income on your Michigan state return. If you take the standard deduction, you can’t deduct gambling losses. To offset winnings with losses, you have to itemize deductions.
For nonresidents, Michigan still wants the 4.25% unless you live in a state with a reciprocal agreement: Illinois, Indiana, Kentucky, Minnesota, Ohio, or Wisconsin. If you live in one of those, you just pay tax to your home state. Check the Michigan Treasury reciprocity info for more details.
Michigan doesn’t add extra state-level surtaxes on gambling income. But a few cities – like Detroit, Grand Rapids, and some others – have their own local income taxes, usually between 1% and 2.4% depending on whether you live or work there. If you’re in one of these cities, your gambling winnings might get hit with a local rate on top of state and federal taxes.
You report these local taxes on a separate city income tax return. The casino or sportsbook won’t withhold this for you, so it’s on you to figure out and pay when you file. Always check your city’s tax rules to see what applies. You can find city forms at Michigan City Income Tax.
Federal law says gambling operators have to withhold 24% federal tax if your win meets certain thresholds:
Michigan also requires operators to withhold 4.25% state tax on lottery prizes and some gambling wins.
If your win doesn’t meet these thresholds, you won’t see automatic withholding. Still, you’re required to report the income on your federal Form 1040 and Michigan state return. You can find more on federal forms at the IRS W-2G page.
Lottery winners usually pick between a lump sum and an annuity (spread out over years). Both get taxed fully, but the timing changes things.
If you take a lump sum, you get all the money at once and pay federal and state tax based on that year’s income. That might shove you into a higher tax bracket.
With an annuity, payments come over decades and each year’s payment is taxed as income that year. This can help you stay in a lower tax bracket, but total taxes over time can still add up.
Your choice affects your cash flow and how much you pay upfront in taxes. If you’re unsure, it’s smart to chat with a tax pro or check out the Michigan Department of Treasury for more info.
If you use a gambling winnings tax calculator, you’ll quickly see what you’ll owe. Here’s how it shakes out with some basic examples:
Example 1: Small Win
Example 2: Mid-Sized Win
Example 3: Jackpot Win
You have to report all gambling and lottery winnings as taxable income to both the IRS and the State of Michigan. The forms you choose, where you enter winnings, and how you keep records will decide whether you file correctly and avoid headaches with penalties.
Casinos, sportsbooks, and the Michigan Lottery send you Form W-2G if your winnings hit certain thresholds – like $1,200 or more from slots or bingo, or $5,000+ from poker tournaments. They also send a copy to the IRS. You can learn more about W-2G requirements on the IRS site.
Smaller wins might not get you a W-2G, but you still need to report them. Sometimes you’ll get a 1099-MISC for non-cash prizes like a car or a trip.
On your federal return, gambling winnings go on Form 1040, usually through Schedule 1 (Additional Income). If you want to deduct gambling losses, you have to itemize using Schedule A. Your losses can’t be more than your winnings.
Winnings boost your adjusted gross income (AGI), which might nudge you into a higher tax bracket or mess with your eligibility for some credits.
Michigan taxes gambling winnings at a flat 4.25% state income tax rate. You have to include all winnings on your Michigan return, even if nobody withheld state tax at payout. Official details are at the Michigan Department of Treasury.
On the MI-1040 form, you report gambling winnings as part of your income. If you’re a non-resident who won in Michigan, you still owe Michigan tax on those winnings. Some states have reciprocity agreements, so you might be able to claim a credit in your home state and avoid double taxation. Check your state’s department of revenue for specifics.
Michigan doesn’t let you subtract losses from winnings directly on your state return. You have to report the full amount of your gambling income.
Federal and Michigan state tax returns are due April 15 each year, unless that falls on a weekend or holiday. If you need more time, you can request an extension with Form 4868 for federal taxes (IRS Form 4868) and Form 4 for Michigan (MI Form 4).
An extension gives you more time to file, but not to pay. You still need to estimate and pay your taxes by the April deadline or you’ll rack up penalties and interest.
You can pay online with the IRS Direct Pay system (IRS Direct Pay) or through the Michigan Treasury Online (MTO) portal (Michigan Treasury Online). You can also pay by check, money order, or electronic funds withdrawal when you e-file.
To back up your reported winnings and losses, keep detailed records. The IRS recommends a gambling log that lists dates, locations, types of bets, amounts wagered, and how much you won or lost. You can check the IRS guidance on recordkeeping for more info.
Helpful documents:
Online casinos and sportsbooks usually let you download annual betting history, but don’t rely on them alone. Good documentation is a must if you want to deduct losses on Schedule A or if the IRS or Michigan Treasury asks questions.
You still have to report gambling and lottery winnings on your tax return, even if you never get a W-2G. Both the IRS and Michigan require you to track your income, so use your own records if a form’s missing.
Casinos and sportsbooks only send a W-2G when your winnings hit certain thresholds. For example, slot or bingo wins of $1,200 or more, keno wins of $1,500 or more, and poker tournament wins of $5,000 or more usually trigger the form. Smaller wins won’t get a W-2G, but you still have to pay tax on them.
Sometimes, if your Social Security number was wrong or the casino couldn’t verify your ID, the form might not get created at all.
If you win smaller amounts across multiple events, each win might be under the threshold, but your total for the year could be much higher. You’re still responsible for reporting the full amount.
If you didn’t get a W-2G, just use your own records to report income. Hang on to receipts, tickets, or your online bet history. Most sportsbooks and casinos let you download a full transaction history for the year.
Add up all your winnings – not just the big ones. Report the total as gambling income on your federal return, and it’ll flow into your Michigan return too.
If you itemize, you can claim gambling losses up to the amount of your winnings. Keep clear records showing the date, type of wager, and amount lost.
If you think a W-2G should’ve been issued but never showed up, reach out to the casino or sportsbook. Most operators can reissue or provide a copy if you ask.
You’ll need to give them your name, player account number, and the date of the win. Sometimes they’ll want a written request or proof of ID before sending anything.
For online platforms, you can usually log in and grab your tax forms straight from your account settings. That’s often the fastest way to check if a W-2G was made.
If you win big and nobody withholds taxes, you might need to make estimated tax payments during the year. The IRS expects you to pay as you go, not just at tax time.
Use Form 1040-ES (IRS Form 1040-ES) to figure out and send in federal estimated payments. Michigan lets you make quarterly estimated payments for state tax too (Michigan Estimated Payments).
Paying in throughout the year helps you dodge underpayment penalties and interest. This really matters if you win multiple times or have income from both gambling and other sources.
Michigan law lets you deduct certain gambling losses on your state return, but only if you meet some specific requirements. These rules mostly follow federal standards, so you need to pay attention to your filing choices, documentation, and limits to steer clear of mistakes.
You can claim gambling losses only if you itemize deductions on your federal return. If you take the standard deduction, you’re out of luck for subtracting losses on your Michigan return.
Your first step is figuring out if itemizing gives you a bigger tax break than the standard deduction. For a lot of folks, the standard deduction is higher, so losses might not help your tax bill.
If you deduct losses on your federal Schedule A, you can also subtract them on your Michigan return. But if you didn’t itemize federally, you can’t create a separate deduction just for Michigan. Check the Michigan Treasury information for the latest rules.
You can’t deduct more than you won. If your winnings total $4,000 for the year, your deduction for losses tops out at $4,000, even if you lost $10,000.
This rule blocks you from using gambling losses to offset other income. The deduction only balances out reported gambling winnings.
For example:
Winnings | Losses | Deductible Loss |
---|---|---|
$2,500 | $5,000 | $2,500 |
$7,000 | $3,000 | $3,000 |
This cap applies at both the federal and Michigan state level. You have to report all winnings as income, then subtract only the allowable portion of your losses.
You need clear records if you want to deduct gambling losses. The IRS and Michigan Department of Treasury expect good proof if they decide to look at your return.
A solid gambling log should include:
Digital betting platforms usually give you account statements, but keeping your own diary is smart. If you don’t have proper documentation, the deduction could get denied. Staying organized all year makes tax season way less stressful.
Most people file as casual gamblers. If you’re in this crowd, you report winnings as “Other Income” and deduct losses only if you itemize. Your losses can’t be more than your winnings.
Professional gamblers, who treat gambling as a business, use Schedule C for income and expenses. But even pros can’t deduct losses beyond winnings.
The big difference? Professionals may deduct business expenses, like travel, in addition to wagering losses. Casual gamblers can’t. If you gamble a lot, think carefully about whether you really meet the IRS definition of a professional – getting this wrong can mean audits or penalties. The IRS Topic No. 419 has more info.
Lottery winnings in Michigan count as taxable income for both the state and the IRS. Whether you win from scratch-offs, raffles, or casino drawings, what you keep depends on how much you win, how you get paid, and whether taxes get withheld upfront or you owe later. For more details, visit the Michigan Lottery Tax FAQ and the IRS gambling winnings page.
Michigan hits lottery winnings with a 4.25% state income tax. Federal law also requires a 24% federal withholding on prizes above certain amounts (IRS W-2G info).
If you live in Michigan, you owe state tax on all your lottery wins, even if you bought the ticket somewhere else. Nonresidents who win in Michigan pay the 4.25% Michigan tax on their in-state prizes too.
For prizes over $5,000, both federal and state taxes come out before you get paid. Smaller wins might not have taxes withheld up front, but you still have to report them on your tax return.
The Michigan Lottery sends out Form W-2G for prizes above $600. This form shows your winnings and any taxes withheld, and the IRS gets a copy too. See Michigan Department of Treasury – Income Tax Forms for more details.
How you claim your prize really depends on the amount. For prizes under $600, you can usually just cash out at a retailer. No taxes get withheld at that stage, but don’t forget – you still need to report these winnings.
For prizes between $601 and $5,000, you’ll get a W-2G form, but Michigan won’t automatically withhold state taxes. You’re still on the hook for both state and federal tax when you file.
For prizes over $5,000, the Michigan Lottery withholds 24% federal and 4.25% state tax before cutting your check. At least part of your tax bill gets handled upfront.
Depending on your total income and tax bracket, you might owe more than what was withheld, so you’ll need to pay the difference when you file. Check the state tax forms for details.
Win big? You’ll have to pick between a lump sum payment or an annuity paid out over years.
A lump sum gives you all your winnings right away, but you pay taxes on the full amount in that year. That can bump you into a higher tax bracket.
An annuity spreads the money out, so you’re taxed on smaller amounts each year. You can’t get the whole prize at once, though, and the total payout might end up less than the headline jackpot because of interest adjustments.
Honestly, there’s no one-size-fits-all answer here. You’ve got to weigh your own financial needs and long-term plans. Maybe talk to a tax pro before you decide.
If you hand someone a winning ticket, the IRS sees it as you winning and then giving the money away. You’re responsible for the tax on those winnings. If the gift is big enough, it might also trigger federal gift tax rules (IRS Gift Tax Form 709).
When a group shares a winning ticket, you need to file Form 5754 with the Michigan Lottery. That form lists each winner, their share, and their taxpayer info. Then, everyone gets their own W-2G and pays taxes on just their portion.
If you skip this step, the IRS and state might treat the whole prize as belonging to one person, and that person gets stuck with all the taxes. Good documentation keeps things fair and tidy.
If you split a winning Michigan lottery ticket with others, the IRS and state expect you to report the prize accurately. Each person claims their share, and the right forms help make sure taxes are withheld fairly and records aren’t a mess.
If you win with a group, the IRS wants you to fill out Form 5754 to split the prize among all members (IRS Form 5754). You list everyone’s name, address, and Social Security number. The lottery uses that info to issue separate tax forms for each person.
If you don’t use Form 5754, the prize might be reported under just one name. That person ends up with all the tax headaches instead of sharing the load.
Fill out the form right away when you claim the prize. Each member signs and shows ID. This way, both federal and Michigan taxes – the 24% federal withholding and 4.25% state withholding – get applied to each person’s share.
Once you submit Form 5754, the lottery sends a W-2G tax form to each group member. That form shows the winnings and taxes withheld. Each person then reports their share on their own federal and Michigan returns.
Say a $100,000 prize gets split five ways. Each person gets a W-2G for $20,000 and the right withholdings. That way, nobody gets taxed on the full $100,000 by mistake.
Hang on to your W-2G for tax time. The IRS and Michigan Treasury get copies too, so your numbers need to match.
A written lottery pool agreement can save you a ton of trouble. List all members, what each pitched in, and how you’ll split winnings. Everyone should sign and keep a copy.
Without an agreement, arguments can break out over who gets what. If the ticket holder tries to claim the prize alone, it can get ugly – lawsuits, tax messes, you name it.
The agreement also makes Form 5754 easier to fill out. It proves who’s entitled to what if the IRS asks questions.
Sometimes, one person claims the prize and skips Form 5754. The lottery issues one W-2G in that person’s name, so the IRS sees it as their income.
If that person later splits the money, the IRS might call those payments gifts and expect gift tax paperwork.
Fixing this after the fact can be a mess. You might need a tax pro or even a lawyer. Amending returns and proving the original group setup isn’t easy. It’s way better to use Form 5754 up front.
Big win on Mega Millions or Powerball? Both federal and state tax rules apply. The state where you bought the ticket might withhold tax, but Michigan taxes your winnings too if you live here. How you report and claim credits depends on where you bought the ticket and how you take your payout (Michigan Income Tax Forms).
If you buy a winning ticket in another state, that state gets first crack at taxing your prize at its own rate. For example, win Powerball in Illinois, and Illinois may withhold state tax before you see a dime.
Michigan taxes all your income as a resident, no matter where you earned it. So even if another state already took a cut of your Mega Millions or Powerball winnings, you have to report the whole thing on your Michigan return.
Some states, like Florida or Texas, don’t have a state income tax. Buy your ticket there, and only federal and Michigan taxes apply. If you win in a state that does tax, you’ll deal with both states’ rules.
Michigan lets you claim a credit for income taxes you paid to another state on the same winnings. This stops you from getting taxed twice on the same prize. The credit knocks down your Michigan bill by what you already paid elsewhere, up to Michigan’s 4.25% rate.
To claim this, file Form MI-1040 and include a Schedule TC. You’ll need proof of taxes paid to the other state, like a W-2G or a copy of your return.
The credit only works if another state actually withheld or made you pay tax. If you bought your ticket in a no-tax state, you can’t claim a credit.
If you take your Mega Millions or Powerball winnings as an annuity, you get annual payments for years. Each payment counts as taxable income the year you get it. Both federal and state taxes hit you each year, not just when you first win.
Keep track of your annuity payments and what’s reported on Form W-2G every year. Michigan wants you to include these on your annual return (Michigan Department of Treasury – Income Tax).
If another state withheld taxes when you won, that usually covers the lump sum or first payment. Later years, only Michigan and the IRS tax the annual payments. Good records make sure you report the right income each year.
If you live in Michigan but win the lottery in a neighboring state, you might wonder about reciprocity. Michigan doesn’t have broad deals for lottery or gambling income. Instead, you use the credit for taxes paid to other states.
Nonresidents who win in Michigan pay Michigan’s 4.25% tax on lottery income. For example, if you live in Ohio and win Powerball in Detroit, Michigan withholds its tax before paying you. You’ll report the winnings in your home state and might claim a credit there.
Rules vary, so check if your state gives a credit for Michigan taxes. That helps you avoid getting taxed twice on the same lottery win.
If you don’t report gambling winnings, both the IRS and the Michigan Department of Treasury can slap you with penalties, charge interest, or send notices. They get your info straight from casinos and lotteries. If you can’t pay in full, you might have to amend a past return or set up a payment plan (Michigan Payment Plans).
Filing late isn’t the same as paying late. The IRS charges a failure-to-file penalty of 5% per month of unpaid tax, up to 25%. Michigan has similar penalties.
If you file on time but can’t pay, the failure-to-pay penalty is usually just 0.5% per month of the unpaid balance. Interest keeps piling up on both federal and state taxes until you pay off the balance.
It’s better to file your return even if you can’t pay the whole amount. That way, you dodge the bigger late filing penalty and can work out a payment plan for the rest.
Casinos, racetracks, and lotteries send Form W-2G or sometimes Form 1099-MISC when you win enough. The IRS and the Michigan Treasury get copies automatically.
If you forget to report winnings, the IRS and state compare your return to the forms they got. If things don’t match, you’ll likely get a CP2000 notice from the IRS, asking for more tax, penalties, and interest.
Michigan uses federal data too. If your state return doesn’t line up, you might get a bill or face an audit. These notices are mostly automated, and it’s tough to argue without good records.
If you realize you missed gambling winnings, you can fix it by filing Form 1040-X to amend your federal return (IRS Form 1040-X). Michigan needs an amended return too, usually with a copy of the federal fix (Michigan Amended Return).
The sooner you amend, the less you’ll pay in penalties and interest. Waiting for a notice usually means more costs.
If you can’t pay in full, you can request a payment plan. The IRS and Michigan both offer installment agreements (IRS Payment Plans, Michigan Payment Plans). You’ll pay interest and maybe some fees until you’re squared up, but at least you avoid harsher penalties.
Think about reaching out to a tax pro if you get a notice from the IRS or Michigan Treasury, owe a large amount, or if you haven’t reported winnings from multiple years.
A tax professional can dig through your records, figure out the right tax amount, and talk to the IRS or the state for you. They’ll also help you file amended returns and work out payment plans that actually fit your budget.
If you’re facing steep penalties, a pro might ask for penalty relief or try to negotiate with the agencies. It’s not a guarantee, but sometimes they can trim down what you owe.
Yes, Michigan taxes gambling and lottery winnings as part of your individual income tax. If you include winnings in your federal adjusted gross income, you also need to report them on your Michigan return.
This covers casino jackpots, lottery prizes, sports bets, and horse racing payouts. Even if you win money in another state, you still have to report it if you live in Michigan.
Some cities, like Detroit, tack on local income taxes too. These come on top of state and federal taxes.
Michigan doesn’t have a special gambling winnings tax rate. Instead, you pay the standard Michigan income tax rate on all your taxable income, including gambling winnings.
Here’s where it gets tough: Michigan won’t let you deduct gambling losses on your state return. You have to pay tax on the full amount you win, not just what’s left after losses.
For example:
This rule often bumps up your state tax bill more than you’d expect.
In Michigan, gambling and lottery winnings count as taxable income. You have to report them on both your state and federal tax returns. How you get paid can change what you owe.
Report all gambling and lottery winnings on your Michigan tax return. The state includes these winnings in your adjusted gross income. Michigan doesn’t allow a deduction for gambling losses on your state return, even if you itemize on your federal return.
Michigan charges a flat 4.25% state income tax rate on lottery and gambling winnings. That’s on top of any federal taxes. The lottery or casino might withhold some taxes before you get your money.
Start with your total prize. Subtract any federal and state withholdings, then figure your federal tax rate based on your bracket and add Michigan’s 4.25% state tax. You can use online calculators for a quick estimate. For more details, check the Michigan Department of Treasury’s official site: https://www.michigan.gov/taxes.
Yep. Smaller prizes usually don’t have taxes taken out up front, but you still need to report the income. For bigger prizes, taxes are often withheld when you get paid, though you might owe more when you file your return.
If you pick a lump sum, you get all the money at once and pay taxes on it that year. With an annuity, you get payments over time, and each year’s payment is taxed as income for that year.
For more information on forms and reporting, visit the official IRS site: https://www.irs.gov/forms-pubs/about-form-w-2g and the Michigan Department of Treasury’s forms page: https://www.michigan.gov/taxes/forms.
Yep, Michigan does things a bit differently. The state taxes gambling winnings at a flat 4.25% rate. On the other hand, federal tax rates depend on your total income and filing status. Usually, the IRS withholds 24% from gambling winnings, but when you actually file your taxes, your final rate could be higher or lower. If you want details straight from the source, check out Michigan’s Department of Treasury and the IRS info on Form W-2G for gambling winnings.
