Winning money from a lottery ticket, casino game, or sports bet in South Dakota feels thrilling, but there’s a catch: taxes. All gambling winnings over $5,000 in South Dakota get hit with a 24% federal withholding tax, but the state leaves your winnings alone. So, you’ll always walk away with a little less than the jackpot you saw on the screen, and you might even owe more when tax season rolls around.

Whether you’re scratching off a ticket, hitting a jackpot, or cashing in on a sports bet, it’s smart to know how taxes work. You’ll want to know how to report your winnings, which forms to look out for, and what to do if you win with friends or lose track of paperwork.

With a few straightforward rules and online tools like tax calculators, you can get a pretty good idea of your real take-home before you even claim your prize. Here’s what you need to know if you get lucky in South Dakota.

Key Takeaways

• Federal taxes apply to gambling winnings in South Dakota, but the state doesn’t tax your prize
• Reporting rules and forms depend on what you win and how much
• You might offset winnings with documented gambling losses

How South Dakota Taxes Gambling & Lottery Winnings: The Basics

South Dakota skips taxing lottery or gambling winnings, but you still need to deal with the IRS. The kind of gambling, your residency, and how much you win all play a role in what you owe and if anything gets withheld up front.

What Counts as Gambling Income in South Dakota? (Sportsbooks, Casinos, DFS, Raffles)

The IRS treats any money or prize you win from gambling as taxable income. That covers casino jackpots, sports betting, DFS contests, poker tournaments, and even raffles. If you win a car or a trip, you’re supposed to report the fair market value as income too.

You can gamble legally at tribal casinos, licensed sportsbooks, and through the South Dakota Lottery (South Dakota Lottery). The state doesn’t take a cut, but the feds expect you to report every dollar on your annual tax return.

Even if taxes aren’t withheld on smaller wins, you still have to report them. Bigger wins can trigger automatic withholding and extra paperwork.

Federal vs. South Dakota Treatment: What’s Taxed Where

The IRS wants a W-2G form for gambling winnings of $600 or more. If you win over $5,000, whoever pays you must withhold 24% for federal income tax. And even if no one withholds anything, you still have to report all winnings when you file with the IRS.

South Dakota doesn’t tax gambling or lottery income. Unlike a lot of other states, you won’t see any state tax on your winnings here. No state income tax means you’re only dealing with federal rules if you win in South Dakota.

Still, keep good records—receipts, tickets, statements—showing your wins and losses. If you itemize, you might be able to deduct gambling losses at the federal level (IRS W-2G info).

Residents vs. Nonresidents: Which Winnings Are Taxable

It doesn’t matter if you live in South Dakota or just visit—there’s no state tax on gambling wins here. Residents don’t pay state tax, and neither do nonresidents who win while visiting.

But if you’re from a state that taxes gambling winnings, you’ll need to report South Dakota wins there. Say you’re from Minnesota and win big in Deadwood—you’ll have to mention it on your Minnesota return.

South Dakota residents only need to worry about the IRS. Out-of-staters should double-check their own state’s rules to avoid surprises.

Withholding vs. Estimated Tax: When Each Applies

If you hit $5,000 or more in gambling winnings, the payer withholds 24% for federal income tax right away. That’s the IRS making sure they get something up front.

Below $5,000? Usually, no withholding. But if you rack up a bunch of smaller wins, you might need to make estimated tax payments during the year to dodge penalties. It’s worth keeping an eye on if you’re a frequent player.

Keep in mind, if you’re in a higher tax bracket, that 24% might not be enough. You may need to pay more later, either through estimated payments or when you file your return.

Are Gambling Winnings Taxable in South Dakota? State & Federal Rules

You must report all gambling winnings on your federal tax return. South Dakota doesn’t tax those winnings, but federal withholding rules still apply, and you’ll get tax forms depending on your payout.

Does South Dakota Tax Gambling Winnings?

South Dakota doesn’t tax gambling winnings at all. With no personal income tax, you keep the full value of your prize without any state withholding.

This covers all gambling—casino jackpots, lottery prizes, sports betting, video lottery. Win $50 on a scratch ticket or $5,000 at a slot machine, and the state won’t take a dime.

Even though the state leaves you alone, the IRS doesn’t. You have to report both cash and non-cash gambling prizes, like cars or trips, on your federal return.

Is There a Separate Gambling Winnings Tax in South Dakota?

There’s no separate gambling winnings tax for individuals in South Dakota. The state taxes casinos and gambling operators through licensing fees and revenue-based assessments, but that doesn’t touch your personal winnings.

So, as a player, you don’t have any extra state filing requirements—just follow the federal tax rules.

The IRS might withhold 24% from prizes over $5,000. Smaller wins aren’t automatically withheld but must still be reported. If the withholding doesn’t cover your tax bill, you’ll have to pay the difference.

When Do W-2G/1099 Forms Get Issued for South Dakota Players?

Casinos and lotteries give you a Form W-2G when your winnings hit certain amounts. For example:

• $1,200 or more from a slot machine
• $1,500 or more from keno
• $5,000 or more from poker tournaments
• $600 or more from lotteries or raffles if the payout is at least 300 times your wager

If you win less, you probably won’t get a W-2G, but you still have to report it. Sometimes you’ll get a Form 1099-MISC for non-cash prizes, like a vacation package.

Both you and the IRS get these forms, so skipping them can lead to penalties. Keep your own records to back up your reported income.

Are Crypto Payouts or Promo Credits Taxable in South Dakota?

If you get gambling winnings in crypto, the IRS treats it as taxable income. You have to report the fair market value in U.S. dollars when you receive it. South Dakota doesn’t add any extra taxes since there’s no personal income tax.

Promo credits or free play bonuses aren’t taxable when you get them. But if you win money using those credits, the winnings count as taxable income. It’s the same whether you’re paid in cash, merchandise, or crypto.

With gambling getting more digital, it’s important to keep up with federal law. For a broader look at how the industry shapes these rules, check out updates from the American Gaming Association. If you’re looking for official info on gambling forms, visit the South Dakota Department of Revenue or the IRS W-2G instructions.

South Dakota Gambling Tax Rates & Withholding Percentages

When you win money from gambling or the lottery in South Dakota, your tax situation depends on both state and federal rules. The state doesn’t tax individual winnings, but the IRS requires federal withholding on bigger prizes. How you claim your prize—lump sum or annuity—also changes what you keep.

State Income Tax Rate(s) Applied to Gambling Wins in South Dakota

South Dakota doesn’t have a state income tax. So, you don’t owe any state income tax on gambling or lottery winnings, no matter how big the prize is.

Win $500 or $5 million, and the state doesn’t take a penny. That’s pretty rare—most states want their share, but not here.

Even though the state doesn’t tax your winnings, you still have to report them on your federal return. The IRS expects you to include gambling income, whether it’s from the lottery, casinos, sports betting, or elsewhere.

Because there’s no state income tax, you won’t see a state withholding line on your prize check. Only federal taxes get taken out.

Local/City Surtaxes (If Any) That May Apply in South Dakota

South Dakota doesn’t let local or city governments charge income taxes. No city-level surtaxes on gambling or lottery winnings, period.

Whether you’re in Sioux Falls, Rapid City, or a tiny town, your winnings are treated the same. You won’t see any extra local deductions.

Some states tack on city or county taxes, but not here. That makes tax planning simpler—you just deal with the feds.

Still, keep records of your winnings. If the IRS asks for proof, you’ll want accurate info to avoid headaches.

Federal and State Withholding Thresholds & Percentages

The IRS requires federal withholding on gambling and lottery winnings over $5,000. The standard withholding rate is 24%.

For example:

• Win $10,000 – $2,400 withheld, you take home $7,600.
• Win $100,000 – $24,000 withheld, you take home $76,000.

If your prize is between $600 and $4,999, you’ll get a W-2G form but no automatic withholding. You still have to report the full amount on your tax return.

South Dakota doesn’t add state withholding, so you only need to worry about the federal percentage. Depending on your total income, your actual tax rate could be higher than 24%, and you might owe more at tax time.

Lump Sum vs. Annuity: How Your Choice Can Affect Taxes

If you win a big jackpot, you might get to pick between a lump sum or annuity.

• Lump sum: You get the whole prize at once. Federal withholding happens right away, and the entire amount counts as income for that year. This could push you into a higher tax bracket.
• Annuity: You get yearly payments over a set period. Each payment is taxed in the year you receive it, which might keep you in a lower bracket.

Your choice affects your tax bill and long-term plans. A lump sum gives you all the money up front but might mean higher taxes. An annuity spreads it out and could lower your yearly tax bite.

Want to see which option leaves you with more? Try a lottery tax calculator or check out the IRS page on gambling winnings for more details.

Sample Calculations: Small Win, Big Win, Jackpot (Use Calculator)

Let’s break down how much you actually keep with three examples:

Small win ($1,000)

• No federal withholding
• You get $1,000
• Still have to report it on your tax return

Big win ($10,000)

• 24% federal withholding = $2,400
• You take home $7,600
• You might owe more at tax time, depending on your tax bracket

Jackpot ($5 million lump sum)

• 24% federal withholding = $1.2 million
• You walk away with $3.8 million at first
• Your actual tax bill could be higher than 24% when you file

A lottery tax calculator gives you a ballpark of your after-tax winnings. It’s handy for comparing lump sum vs. annuity and figuring out if you’ll owe more. You can use the official IRS calculator at irs.gov/payments/tax-withholding-estimator.

How to Report South Dakota Gambling Winnings on Your Taxes (Forms & Deadlines)

Report all gambling and lottery winnings to the IRS, even the small stuff. Federal forms cover this since South Dakota doesn’t tax gambling winnings at the state level. Accurate forms and good records help you dodge penalties and keep everything in order.

Which Forms You’ll Use: W-2G, 1099-MISC, 1040, Schedule 1, Schedule A

Casinos and lotteries usually send you Form W-2G if you win $600 or more, depending on the game and payout. Slot wins of $1,200 or more trigger a W-2G. The IRS requires 24% withholding on winnings over $5,000.

If you get gambling income not covered by W-2G, like promos or prizes, you might get a Form 1099-MISC instead. Both forms show what you need to report.

Report winnings on Form 1040 under “Other Income,” which flows through Schedule 1, Line 8b. If you itemize, you can deduct gambling losses up to your winnings on Schedule A, but you’ll need proof.

Key forms at a glance:

Form	Purpose	When You’ll Receive It
W-2G	Reports gambling winnings	Slot, lottery, poker, keno, bingo, large wins
1099-MISC	Other gambling-related income	Cash prizes, non-cash awards
1040 + Schedule 1	Report winnings as income	Every taxpayer
Schedule A	Deduct losses (itemized only)	Optional if you itemize

Where to Enter Winnings on Your South Dakota State Return

South Dakota doesn’t have a state income tax, so you skip a state return for gambling winnings. You only need to report them on your federal return.

Even though the state doesn’t tax winnings, hang onto your W-2G or 1099-MISC forms. The IRS will want them for your federal return.

If you live in South Dakota but win money in another state, check that state’s rules. Some states withhold taxes from nonresidents. You might need to file a nonresident return there to claim a refund or pay what you owe. For more details, check South Dakota Department of Revenue and the IRS Form 1040 info.

Filing Deadlines, Extensions, and Payment Options

Your federal return (including gambling winnings) is due April 15, unless it falls on a weekend or holiday. If you need more time, file Form 4868 for an automatic extension until October 15 (IRS Form 4868 info).

The extension gives you more time to file, not more time to pay. If you owe taxes, pay by April 15 or you’ll rack up interest and penalties.

You can pay online using IRS Direct Pay, by card, or by mailing a check with a payment voucher. Online payment is quick and gives you instant confirmation. More at irs.gov/payments.

Recordkeeping: Session Logs, Tickets, Bet History, and Bank Statements

The IRS wants proof of your winnings and losses. Keep every W-2G, 1099-MISC, and any receipts or tickets from your gambling sessions.

Keep a session log with:

• Date and location
• Game played
• Amount wagered, won, or lost
• Supporting docs like betting slips or bank statements

If you claim losses on Schedule A, your records need to match what you report. Without proof, the IRS can deny your deduction. Staying organized all year makes tax season way less stressful. The IRS has more on this at irs.gov/taxtopics/tc419.

Didn’t Get Form W-2G in South Dakota? Here’s How to Report Anyway

You still have to report gambling or lottery winnings, even if you never got a Form W-2G. The IRS expects you to track and report all taxable winnings. Since South Dakota doesn’t have state income tax, your focus is federal reporting and good documentation.

Common Reasons a W-2G Isn’t Issued (Thresholds, ID Mismatch)

Casinos and sportsbooks only send a W-2G if your winnings hit certain thresholds:

Type of Gambling	W-2G Trigger Amount	Withholding May Apply
Slots/Bingo	$1,200+	Yes
Keno	$1,500+	Yes
Poker Tournaments	$5,000+	Yes
Sports Bets	300x wager & $600+	Yes

If your winnings are below these, you won’t get a form but still have to report them.

ID mismatches can also cause issues. If your Social Security number or name doesn’t match IRS records, the casino might not file correctly. You’re still responsible for tracking and reporting.

How to Self-Report Using Statements and Bet History

Add up your gross winnings for the year – not just what’s left after losses. The IRS wants the total amount you won before you subtract anything.

Keep a log of your sessions: date, game, location, how much you wagered and won. For online gambling, download your account history. That’ll give you a detailed record of bets, deposits, and payouts.

On your tax return, enter your total gambling income on Schedule 1 (Form 1040), “Other income”. If you itemize, you can claim losses on Schedule A, but only up to the amount you reported as winnings.

Requesting Copies from Casinos/Sportsbooks

If you think you should’ve received a W-2G but didn’t, reach out to the casino or sportsbook. Most casinos track everything tied to your player card and will give you a win/loss statement if you ask.

For online platforms, log in and check the tax documents section. Some sites automatically generate downloadable W-2G forms if you cross the reporting threshold.

Always compare the casino’s records with your own log. If something doesn’t match, your records can back you up with the IRS.

Making Estimated Payments to Avoid Penalties

If you had big winnings and no tax was withheld, you could owe a lot at tax time. To avoid underpayment penalties, make estimated payments during the year.

Use Form 1040-ES to figure out and send quarterly payments (IRS Form 1040-ES info). This is important if you win early in the year and think you’ll owe more than $1,000 in federal tax after credits and withholding.

Pay online through IRS Direct Pay or by mail. Spreading out payments can make life easier and reduce the risk of penalties when you file.

Can You Deduct Gambling Losses in South Dakota? Rules & Limits

You might be able to deduct gambling losses on your federal return, but only if you follow some strict rules. These apply whether you play in Deadwood, at tribal casinos, or buy lottery tickets in South Dakota. The state doesn’t tax your winnings, but the IRS does, and the federal rules control how losses work. Full details are at irs.gov/taxtopics/tc419.

Itemized vs. Standard Deduction: When Losses Can Help

You can only deduct gambling losses if you itemize on Schedule A (Form 1040). If you take the standard deduction, your losses won’t help you at all.

Honestly, for a lot of people, the standard deduction is bigger than what they could itemize. So, itemizing just for gambling losses rarely lowers your taxes.

If you do itemize, gambling losses count as a miscellaneous itemized deduction. They’re not subject to the 2% AGI floor that applies to other deductions. You can deduct the full amount of losses, but not more than your winnings.

Losses Limited to Winnings: How the Cap Works

You can’t use gambling losses to create a net negative against your income. Losses only reduce taxable winnings, not your wages or retirement money.

For example:

• If you win $4,000 and lose $6,000, you can only deduct $4,000.
• If you win $2,000 and lose $500, you can deduct $500.

The IRS makes you report all winnings as taxable income, even if you lost more than you won. The deduction comes separately on Schedule A. This keeps people from offsetting unrelated income with gambling losses.

Proof You Need: Diaries, Receipts, and Digital Logs

The IRS expects detailed records for any gambling loss deduction. Without proof, you’ll probably lose the deduction.

What counts as proof?

• Wagering tickets, receipts, canceled checks
• Statements from casinos or online betting sites
• A gambling diary with dates, locations, types of wagers, amounts won, and amounts lost

Most betting apps let you download transaction histories, which work as evidence. Keep both paper and digital records if you can. The goal is to show a clear, consistent record that ties losses directly to gambling.

Casual vs. Professional Gambler: Different Rules, Different Risks

Most people are casual gamblers. Losses only count as itemized deductions and only up to your winnings. You can’t treat gambling as a business unless you meet strict IRS standards (more info).

A professional gambler – someone who gambles with regularity and intent to earn – may report on Schedule C. That lets them deduct ordinary and necessary business expenses, like travel or research.

But even professionals can’t deduct losses beyond winnings. The main difference? Pros can deduct business expenses separately. If you misclassify yourself as a pro without meeting the IRS criteria, you’re asking for an audit headache.

South Dakota Taxes on Lottery Winnings: Scratch-Offs, Raffles, Casinos & More

In South Dakota, lottery and gambling winnings get taxed differently at the federal and state levels. The state doesn’t collect income tax on lottery winnings, but federal rules still apply, including withholding on bigger prizes and reporting requirements for certain amounts. How you claim, share, or receive your winnings can affect what you keep. For more on state rules, see the South Dakota Lottery and South Dakota Department of Revenue.

State Lottery Withholding for Residents and Nonresidents

South Dakota doesn’t have a state tax on lottery winnings, whether you’re a resident or just visiting. So, you won’t pay state income tax on scratch-offs, raffles, or casino jackpots here (South Dakota Department of Revenue).

But the IRS still requires federal withholding. If your prize is over $5,000, the lottery takes out 24% for federal taxes before you get paid. Smaller wins usually skip withholding, but you still need to report them on your federal return (IRS: About Form W-2G).

Nonresidents follow the same rules. You won’t owe South Dakota state tax, but you must report your winnings to the IRS. Your home state might also want a cut, so check your own state’s tax laws if you live elsewhere.

Claiming Small Prizes vs. Large Jackpots in South Dakota

How you claim your prize depends on the size. For wins between $600 and $4,999, the lottery hands you a W-2G tax form when you collect. This tells the IRS about your win, but they don’t withhold federal tax up front.

For anything over $5,000, the lottery withholds 24% for federal taxes before you see the money. You’ll get a W-2G for your records. If your tax rate is higher than 24%, expect to owe more come tax time.

For prizes under $600, you can usually just grab your cash from a retailer – no tax paperwork involved. Still, you’re required to report those winnings on your federal return, even if you don’t get a form.

Lump Sum vs. Annuity for Lottery Wins: Pros and Cons

If you score a big jackpot, you’ll usually pick between a lump sum or an annuity. A lump sum gives you all the cash now, and the IRS taxes the whole thing that year. That can bump you into a higher tax bracket fast.

An annuity spreads your money out over years. Each payment gets taxed the year you receive it, which might keep your annual taxes lower. Of course, you won’t have full access to your winnings right away.

Honestly, the choice is personal. Lump sums offer flexibility and control, but you’ll need a solid plan for taxes and spending. Annuities give you steady income but not as much freedom.

Gifting Tickets and Sharing Prizes: What to Know

If you gift someone a lottery ticket and they win, the prize is theirs. The IRS taxes the winner, not you. But if the ticket’s value is high before it’s cashed, you might need to think about gift tax rules (IRS: About Form 709).

When you split winnings with others, the IRS wants clear reporting. If several people claim ownership, sort that out before claiming the prize. The lottery can split payments if everyone’s name is on the claim form.

If you claim the prize alone and hand out shares after, the IRS could treat those as gifts and you might have to file a gift tax return. Get agreements in writing and check tax guidance before splitting big prizes. It saves headaches later.

How Are Group Lottery Wins Taxed in South Dakota?

If a group wins, the IRS and South Dakota Lottery treat each person as a separate winner. Federal tax rules apply, but South Dakota doesn’t add state tax. Having the right paperwork and clear agreements helps avoid mistakes and tax surprises.

Using IRS Form 5754 to Split Prizes Correctly

If you’re part of a group win, use IRS Form 5754 to report everyone’s share (IRS: About Form 5754). List names, addresses, Social Security numbers, and each person’s share. The lottery uses this info to prepare W-2G forms for every winner.

If you skip this form, the lottery may pay the full prize to just one person. The IRS then treats the entire amount as that person’s income. Filing Form 5754 ensures everyone gets taxed only on their share.

Fill out the form when you claim the prize. Everyone signs, and the lottery sends copies to the IRS and each winner. This keeps everyone’s tax records straight and avoids confusion later.

One Ticket, Many Winners: W-2Gs for Each Participant

When a group claims a prize, the lottery issues a W-2G tax form to each person listed on Form 5754. This shows your winnings and any federal withholding. For prizes over $5,000, the IRS requires 24% federal withholding from each share.

Say four people win $20,000, each gets a W-2G for $5,000. Since that’s under $5,000 per person, there’s no withholding, but you still report it as income.

Hang onto your W-2G for your taxes. Report your share as gambling income when you file.

Pool Agreements: Avoiding Disputes and Tax Headaches

Lottery pools are everywhere – offices, families, friends. To dodge drama, create a written pool agreement before buying tickets. It doesn’t have to be fancy – a signed note listing members, contributions, and how you’ll split winnings works.

A written record helps if someone later questions who was in the pool. It also backs you up if the IRS wants proof of shared ownership. Without documentation, the IRS might assume the person who cashed the ticket is the only winner.

Keep copies of tickets, payment records, and your agreement. These can save you from legal and tax problems down the line.

If Only One Person Claims the Prize: Fixing It After the Fact

Sometimes just one person claims the prize, even if others chipped in. If that happens, the IRS taxes the full amount as that person’s income, even if they split the money later.

You can try to fix it by filing Form 5754 retroactively with the lottery, but that’s tricky if the prize is already paid. If not possible, the person who got the money may have to report it all and then issue Form 1099 to the others for their shares (IRS: About Form 1099-MISC).

This gets messy and creates extra work at tax time. Best bet? Claim the prize as a group from the start and get the paperwork right.

Taxes on Multi-State Lottery Wins

If you buy lottery tickets in more than one state, things can get complicated. You might owe taxes where you bought the ticket, where you live, or both. Federal rules always apply, but state rules vary and can affect your final payout.

Buying in Another State: Which State Gets to Tax?

If you buy a winning ticket in another state, that state gets first crack at taxing your prize. This holds true even if you live in South Dakota, where lottery winnings aren’t taxed.

For example, if you buy a Powerball ticket in Minnesota and win, Minnesota will withhold state income tax before paying you. Being a South Dakota resident won’t help you avoid that.

The state where you bought the ticket issues a W-2G showing both federal and state withholding. You’ll need this for your taxes.

Credits for Taxes Paid to Other States (and How to Claim Them)

If your home state taxes lottery winnings, you might get a credit if another state already took out taxes. That way, you don’t pay twice.

South Dakota residents don’t need this credit since there’s no income tax. But if you split time between South Dakota and another state with income tax, things get more complicated.

Most states want you to file a resident return, then claim a credit for taxes paid elsewhere. Attach documents like your W-2G or withholding statement to prove what was already taken out. Check your state’s tax agency for forms and instructions (IRS: About Form 1040).

Multi-Year Annuities: Tracking Basis and Yearly Income

If you take a multi-state lottery annuity, you’ll get payments over many years. Each payment is taxable the year you get it.

The state where you bought the ticket can keep taxing each annual payment. If you move, your new state might also want to tax the income.

Keep careful records of what you get each year. Even a simple table helps:

Year	Gross Payment	Federal Tax Withheld	State Tax Withheld	Net Payment

Tracking this makes tax time a little less painful.

Reciprocity and Nonresident Rules That May Apply

Some states have reciprocity agreements to prevent double taxation for people who earn income across state lines. Usually, these cover wages, not gambling or lottery winnings.

If you buy a ticket in a state without reciprocity, you’ll be taxed as a nonresident there. You might have to file both a nonresident return in that state and a resident return at home.

South Dakota residents don’t have to worry about this since there’s no income tax here. But if you just visit South Dakota, check your home state’s rules on credits and reciprocity to avoid overpaying.

What If You Don’t Report Gambling Winnings in South Dakota? Penalties & Interest

If you skip reporting gambling or lottery winnings, you risk penalties from the IRS and possibly your home state. The IRS can hit you with interest, accuracy penalties, or even fraud penalties. How you handle it – whether you fix your return or set up payment – makes a difference.

Late Filing vs. Late Payment: Different Penalties

The IRS sees filing late and paying late as separate problems. If you don’t file on time, the failure-to-file penalty kicks in – usually 5% of what you owe per month, up to 25%.

If you file but don’t pay the full amount, the failure-to-pay penalty applies. That’s 0.5% per month, also capped at 25%.

Interest piles up on top of these. The IRS compounds interest daily from the due date until you pay. Even if you can’t pay, filing on time cuts your penalties.

Filing and paying late together can make your bill balloon. For example:

Situation	Penalty Type	Rate	Maximum
Late Filing	Failure-to-File	5% per month	25%
Late Payment	Failure-to-Pay	0.5% per month	25%

IRS/State Matching of W-2G/1099 Data: Notices and Audits

Casinos, lotteries, and other payers report certain winnings on Form W-2G or Form 1099-MISC. They send a copy to the IRS and sometimes the state. If you leave the income off your return, the IRS’s system flags the mismatch.

You’ll probably get a notice, like a CP2000 letter, showing what you missed and what you owe. If you agree, pay up. If you disagree, you’ll need to provide proof, like loss records or documents showing what you actually won.

If you ignore the notice, the IRS could audit you, add penalties, and charge interest. States with income taxes may send their own notices if your return doesn’t match what’s reported.

Since South Dakota has no income tax, you won’t get a state notice for missing gambling winnings. But if you live in another state and gamble there, that state could contact you if you don’t report your winnings.

Amending Returns (Form 1040-X) and Setting Up a Payment Plan

If you realize you forgot to report winnings, you can file an amended return using Form 1040-X. This lets you fix your income before the IRS finds it and hits you with bigger penalties. You can find the official Form 1040-X and instructions straight from the IRS at irs.gov/forms-pubs/about-form-1040-x.

When you file an amendment, include stuff like W-2G forms, win/loss statements, or receipts. The IRS reviews your paperwork, updates your tax bill, and sends you a notice if you owe more, including any penalties or interest.

If you can’t pay the full amount, you can set up an installment agreement with the IRS. That way, you pay monthly. Sure, interest and penalties keep adding up until you finish paying, but at least the IRS won’t come after you with more aggressive collection tactics as long as you stick to the plan. You can apply for a payment plan online at irs.gov/payments/online-payment-agreement-application.

There’s also a short-term payment extension if you can pay within 120 days. Applying online or calling is usually quicker than mailing in forms. Details are at irs.gov/payments/payment-plans-installment-agreements.

When to Call a Tax Professional

You might handle a small fix yourself, but bigger or messier situations usually need a pro. A tax professional can check your records, figure out if you can claim any gambling losses, and maybe help lower penalties.

If you get an audit notice or a CP2000 letter that makes no sense, a tax pro can help you avoid making things worse. Enrolled agents, CPAs, or tax attorneys can even talk to the IRS for you.

If you’ve got several years of unreported winnings, don’t wait. The longer you leave it, the more the penalties and interest pile up. Sometimes, a good tax pro can even help you negotiate for a break on penalties or work out a settlement.

Does South Dakota State Tax Gambling Winnings?

South Dakota doesn’t have a state income tax. You don’t need to report gambling winnings to the South Dakota Department of Revenue. Unlike a lot of states, there’s no extra state filing for residents. You can check out the South Dakota Department of Revenue info here: dor.sd.gov.

But you still have to report your winnings to the IRS. Federal law says you must include all gambling income, no matter where you won it.

If you win money in a state that taxes gambling, you might have to file a nonresident return there. For example, win at a Minnesota casino, and you could owe Minnesota state income tax, even if you live in South Dakota. Minnesota’s rules are at revenue.state.mn.us/nonresidents.

Does South Dakota Have a Separate Gambling Winnings Tax?

South Dakota doesn’t have a separate gambling winnings tax. Some states hit lottery or casino prizes with their own taxes, but South Dakota just follows the federal rules.

The state does regulate and tax the gambling industry with licensing fees and gaming taxes, but that’s for the operators, not for you as a player.

Your only tax obligation as a player is at the federal level, unless you win in another state that taxes gambling. In that case, you could owe both federal and that state’s taxes.

Keep good records of your wins and losses. The IRS expects detailed reporting, even though South Dakota doesn’t have its own income tax.
