Top-rated sweepstakes casinos for South Dakota players
The three sites below are top picks in South Dakota. Each has a Safety Index of 7.5 or higher, the level at which we are comfortable recommending a casino. The Safety Index measures how likely a site is to treat players fairly and pay out, based on its size, complaints, terms and conditions, and blacklists. We then consider bonuses, user experience, and game quality to match you with the best options.
CrownCoins Casino: best for streak rewards and cheap coin packages
CrownCoins Casino has a High Safety Index of 8.5. It is a very big operator, with estimated annual revenue above $1 billion, and has just one unresolved complaint on our site. It ranks between Stake.us (8.0) and Real Prize (9.7) for safety but leads our South Dakota list for what it gives back to regular players.
The rewards run on several tracks at once. A seven-day login ladder opens at 5,000 Crown Coins (CC) and climbs with each consecutive day, adding Sweeps Coins (SC) and wheel spins as the streak builds. Daily missions and tournaments sit on top of that. The six-tier Crown VIP Club unlocks Coinback from Bronze, a birthday bonus from Silver, a premium coin store from Gold, and a personal host at Emerald.
New accounts receive 100,000 CC and 2 SC after email verification, with no purchase needed. You can then get a bonus of 1,500,000 Crown Coins + 75 SC. However, this is a lighter start than Fortune Wins, which hands out up to 3,000,000 Gold Coins, 3,000 Fortune Coins, plus 20 free spins. That said, the referral program is more rewarding, at 400,000 CC and 20 SC for every friend who spends $14.90.
Coin packages start at $1.99, one of the lowest on our list (only Sportzino is cheaper, at $0.99). CrownCoins accepts Visa, Mastercard, American Express, Discover, and Apple Pay for purchases, while prizes go out via Skrill, bank transfer, or a gift card from 50 SC, with no redemption fees. Gift cards usually arrive right after approval, while cash methods take 1–3 business days. Sweeps Coins carry a 1x playthrough but expire after 60 days without account activity.
The game library is the weak spot. Around 600 titles come from studios such as 3 Oaks Gaming, Playtech, Booming Games, and Slotmill. This is lower than many sites, like Casino.Click and High 5 Casino, which offer over 1,000. There are also no blackjack or roulette tables, only a few live game shows.
On mobile, the iOS app has a 4.8-star rating from more than 136,000 ratings. There is no Android app, so Android players must use the mobile browser.
Pros
Low cost of entry – Coin packages start at $1.99, lower than the $10 average at most sweepstakes sites, and all four major card networks plus Apple Pay are accepted at checkout.
Rewards on several tracks – Login streaks, daily missions, tournaments, and VIP perks all run at the same time, so active players collect coins in more than one way.
Accessible redemptions – Prizes start at 50 SC with no fees, half the 100 SC needed for a cash prize at Real Prize and SplashCoins.
Popular iOS app – The app holds 4.8 stars from over 136,000 App Store ratings, slightly ahead of the Stake.us app (4.7).
Cons
High minimum bets – Many slots start at around 4,000 CC per spin, which can drain a free coin balance within a short session.
🧠 Expert insight: CrownCoins suits players who log in most days. The streak ladder, missions, and VIP perks add up over a week, but only if you keep the streak going. Watch for two things: Sweeps Coins expire after 60 days of inactivity, and the 4,000 CC minimum on many slots burns through Crown Coins quickly, so check the bet size before you start a session.
Stake.us: best for game choice and crypto payments
Stake.us holds a High Safety Index of 8.0, the lowest of our top three for South Dakota. It is a very big casino, with estimated annual revenue above $100 million, and its complaints ratio is good for a site handling that many players. We found no unfair clauses in its terms. The score reflects a few unresolved complaints and a small deduction under other factors in our assessment. Stake.us is run by Sweepstakes Limited, part of the Easygo Gaming group, and launched in 2022.
Its catalog is the largest on our South Dakota list: more than 3,000 slots and 30+ table games from over 40 providers, including around 90 exclusives you will not find at other sites. In-house Stake Originals add quick games such as Plinko and Mines, and live dealer tables cover blackjack, roulette, baccarat, and poker. Craps is the one notable gap.
New players can claim 250,000 Gold Coins (GC) and 25 Stake Cash (Stake's version of Sweeps Coins) through our link, well above the 2 SC offered by CrownCoins and Real Prize. The daily bonus pays 10,000 GC and 1 SC, and a free 1,000 GC top-up kicks in whenever your balance drops below 10 GC. Regular players can also enter a 50 million Gold Coin race, weekly draws, and multiplier drops.
The catch comes at redemption. You must play Stake Cash through three times before you can redeem it, compared with 1x at CrownCoins and Real Prize. Redemptions are also closed-loop: coins bought by card are redeemed in fiat, and coins bought with crypto are redeemed in crypto. More than 20 cryptocurrencies are supported, redemptions take up to three days, and the $50,000 daily limit is far higher than the $10,000 caps at CrownCoins and Real Prize.
Support runs around the clock via live chat, although there is no phone line, and the responsible gambling tools are thinner than at some rivals.
Pros
Deepest game catalog – More than 3,000 slots and 30+ table games from over 40 providers, compared with 2,000+ games at Fortune Wins and 1,800+ at Sportzino.
Large sign-up offer – 250,000 GC and 25 Stake Cash through our link, compared with up to 170,000 GC and 7 SC at Sportzino.
Crypto flexibility – More than 20 coins for purchases and redemptions, while Real Prize accepts no crypto at all.
Round-the-clock support – Live chat runs 24/7, a channel Real Prize does not offer.
Cons
Closed-loop redemptions – Prizes return through the same currency type you paid with, so a card buyer cannot redeem in crypto, or the other way around.
🧠 Expert insight: The 3x playthrough is the number to plan around. Every 25 Stake Cash you receive must be wagered as 75 Stake Cash in total before you can redeem it, so the route to a prize is longer than at a 1x site. If game variety matters most to you, or you already hold crypto, Stake.us is a good fit. Check network fees before redeeming a small prize, because they come out of the amount you receive.
Real Prize: best safety score and low gift card minimums
Real Prize has a Very High Safety Index of 9.7, the highest score on our South Dakota list. Realplay Tech Inc. launched the site in 2023, and its lobby is cleanly organized, with exclusive titles easy to find.
Over 700 games come from 13 providers, including Evolution, NetEnt, Red Tiger, Nolimit City, Relax Gaming, and Thunderkick. That is a smaller catalog than High 5 (1,500+) or Sportzino (1,800+), but it includes six to eight live dealer tables for blackjack, roulette, and baccarat. Only one of those is live blackjack, and its minimum bets are high.
New accounts receive 100,000 Gold Coins and 2 Sweeps Coins once the email address is verified, with a 1x playthrough. An optional starter deal adds 500,000 GC and 60 SC for $19.99. After that, the daily login bonus pays at least 5,000 GC and 0.30 SC, rising with your loyalty level, and referrals pay up to 200,000 GC and 70 SC.
You can buy coins with Visa, Mastercard, Apple Pay, or Skrill. Unfortunately, there is no crypto option. Prizes go out as Prizeout gift cards from 45 SC or as Skrill cash from 100 SC, up to $10,000 a day. There is no live chat, so support questions go through the site's other channels.
Pros
Top safety score – A Safety Index of 9.7, ahead of Sportzino (9.1) and CrownCoins (8.5), with no unresolved complaints on our site.
Low gift card threshold – Gift card prizes start at 45 SC, below the 50 SC minimum at High 5 and Sportzino.
Live dealer tables – Streamed blackjack, roulette, and baccarat, which CrownCoins does not offer.
Steady daily value – At least 5,000 GC and 0.30 SC every day, plus referral rewards of up to 200,000 GC and 70 SC.
Cons
No live chat – Help comes through slower channels, which matters most when a first redemption or ID check needs attention.
🧠 Expert insight: If you are not set on cash, the gift card route at Real Prize reaches a prize with less than half the Sweeps Coins needed for a Skrill payout (45 SC against 100 SC). Upload your ID and proof of address as soon as you open the account. Without live chat, any hold-up during a first redemption takes longer to sort out, so clearing verification early saves time later.

How we judge sweepstakes casinos for South Dakota players
Without a state license to lean on, South Dakota players depend on the checks a site passes before they sign up. Our USA casino review framework starts with the Safety Index, then follows each platform from registration through prize redemption. Here is what we look at, and what you can check for yourself.
Checking bonus value and the fine print
A big headline number means little if the terms behind it are strict. We weigh the free coins offered in online casino bonuses against the attached conditions.
No purchase offers – Compare the Sweeps Coins you get for free, not only the Gold Coins, as the former has real money value. On our South Dakota list, no deposit Sweeps Coins on sign-up can range from none at Spinfinite to 25 Stake Cash at Stake.us.
Playthrough – Check how many times free SC must be played before redemption. Most sites on our list use 1x, while Stake.us asks for 3x.
Daily and loyalty rewards – A fixed daily drop is the baseline. Login streaks, missions, and tiered VIP clubs, such as the six levels at CrownCoins, add more over time.
Referral terms – Look at the payout per friend and the spend needed to unlock it, since a big reward can hide a high threshold.
Coin expiry – Find out how long Sweeps Coins stay valid and what counts as activity, so an unused balance does not disappear.
Redemption thresholds – Gift card minimums are often far lower than cash ones. Spinfinite starts gift cards at 10 SC, while most cash redemptions on our list need 50 to 100 SC.
💡 Expert tip: Check each site's daily redemption cap as well as its minimum. Caps are set by the casino, not by South Dakota law, and on our list they range from $2,000 a day at Spinfinite to $50,000 at Stake.us.
Sizing up a game library
A sweepstakes casino must still be worth your time as entertainment, so we look at how many top online casino games it offers, what kinds, and who makes them.
Library size – Catalogs vary widely in South Dakota, from 190+ games at SplashCoins to more than 3,000 slots at Stake.us.
Game types – Slots dominate everywhere. Table games, live dealers, and fast originals such as crash and Plinko separate the fuller libraries.
Providers – A broad mix of the best software studios is a good sign of quality and variety. Real Prize works with 13 studios, including Evolution and NetEnt, whereas MyPrize offers over 30.
RTP information – Each game's Return to Player (RTP) should be shown in its info screen rather than buried in the terms.
Mobile performance – Native sweepstakes casino apps usually run more smoothly than a browser.
💡 Expert tip: Spin a few games with Gold Coins before you buy any package. It shows you how the games load on your connection and whether the minimum bets suit your balance.
Signs a sweepstakes site is safe to use
Safety carries the most weight in our assessment. The Safety Index looks at a casino's size, its complaints relative to that size, unfair terms, blacklists, win and withdrawal limits, and links to related casinos. Beyond the score, here are a few other signals to check whether a casino is safe.
Clear ownership and eligibility – Reputable sites name the company behind them and list accepted states in their terms. Every recommended site on this page accepts South Dakota players.
Account security – Secure Sockets Layer (SSL) encryption is the minimum. Two-factor authentication (2FA), where offered, adds a useful layer of protection for your coin balance.
Responsible gambling tools – Look for purchase limits, session reminders, cool-off periods, and self-exclusion inside your account, not only a helpline link.
Local copycats – The South Dakota Commission on Gaming has warned about fake sites that copy the branding of Deadwood and tribal casinos. No licensed South Dakota casino runs a real-money gambling website.
💡 Expert tip: Always sign up via trusted links like the ones on our toplist. Avoid random links on social media or other platforms.
Coin purchases, redemptions, and fees
We compare how easy it is to buy coins, how quickly prizes arrive, and what each step costs you. Choosing a trusted casino payment method can save you from many of the common problems players experience at online casinos.
Purchase methods – Cards are accepted everywhere. CrownCoins also takes Amex, Discover, and Apple Pay, while Stake.us adds more than 20 cryptocurrencies.
Entry price – The smallest coin packages on our list start at $0.99 at Sportzino and $1.99 at CrownCoins.
Redemption speed – Timing depends on the method: gift cards often arrive instantly or within a day, while bank transfers typically take 1–5 business days. If you want fast casino payouts, your method matters more than anything.
Fees – Most redemptions are free, but crypto payouts carry network fees that make a noticeable dent in small prizes.
Identity checks – Every legitimate site verifies your ID before paying out. Some run automated checks in minutes, while others review documents by hand.
💡 Expert tip: For small prizes, gift cards are usually the best payout route at casinos as they usually have the lowest minimums. Spinfinite pays gift cards from 10 SC, against 100 SC for a cash redemption.
Putting customer support to the test
Support is easiest to judge by using it, so we contact each site's team during our review rather than relying on the channels it lists.
Live chat – Check whether chat is staffed by people, and when. Stake.us runs chat 24/7, while CrownCoins does not.
Email and forms – Sites without live chat rely on slower channels, so reply times matter more there.
Help center – A useful FAQ explains redemption minimums, playthrough, and ID checks in plain terms, not only how to register.
Quality of answers – Agents should answer the question you asked with the site's own rules, rather than pasting a generic script.
💡 Expert tip: Ask support a question about ID verification before you buy any coins. How quickly and clearly support replies can show how they might handle a redemption problem.
Keeping our South Dakota ratings current
Sweepstakes terms and state rules both change often, so we keep checking sites after a review goes live.
Terms and conditions – When a site changes its rules, we reassess them and adjust the Safety Index if a new term is unfair.
Ownership and payouts – A change of owner or a pattern of slower redemptions can trigger a fresh review of a casino's score.
State developments – We follow the South Dakota Legislature and the Commission on Gaming for any move on sweepstakes or online play.
💡 Expert tip: If a casino treats you unfairly, you can submit a complaint to Casino Guru. Our team investigates for free, and unresolved complaints feed into a casino's Safety Index.
What South Dakota law says about online casinos in 2026
South Dakota allows casino gambling, but only in person. Currently, real money online casinos have no legal route in the state, and a 2026 attempt to put statewide mobile sports betting to voters stalled in the House.
Real money online casinos – Not authorized. SDCL Chapter 22-25A bars anyone in the gambling business from taking bets over the internet or running an internet gambling site in the state. A first offense is a Class 6 felony, and each bet counts as a separate violation.
Sweepstakes casinos – No specific law. South Dakota has no statute on dual-currency sweepstakes sites and, as of November 2026, no enforcement action against them. They sit outside the state's licensing system, so their status could change if lawmakers act.
Sports betting – Legal in person only, at Deadwood and tribal casinos, since September 2021. A 2026 resolution to let voters approve statewide mobile betting was rejected by a House committee.
Land-based and tribal casinos – Legal. Deadwood has offered regulated gaming since 1989, and nine tribes run casinos under compacts with the state. Players must be 21.
Lottery and video lottery – Run by the South Dakota Lottery. Tickets are sold to players 18 and over, while video lottery terminals are 21+.
This is a snapshot, not legal advice.
Recent gambling news from Pierre to Deadwood
South Dakota's gambling debate in 2026 has centered on mobile sports betting, while Deadwood's in-person market has continued to grow.
September 16, 2026 – The US House Ways and Means Committee voted 38-5 to repeal the federal 90% cap on gambling loss deductions, backdated to January 1, 2026. The bill is not yet law.
August 2026 – Deadwood gaming activity for July came in 4.05% above July 2025, leaving the calendar year 8.63% ahead.
June 15, 2026 – An amended rule for Deadwood's voluntary self-exclusion list took effect.
April 2026 – Deadwood reported first-quarter gaming revenue up 11.44% on the same period in 2025.
March 2026 – A House committee voted 11-2 against Senate Joint Resolution 504, which would have asked voters on November 3 to approve sports betting, with tax revenue set aside for property tax relief. The Senate had passed it 23-10.
August 2025 – The Commission on Gaming issued a public warning about fake online casinos copying the branding of licensed Deadwood and tribal venues.
Sweeps bonuses available to South Dakota players
Sweepstakes sites cannot take real-money deposits, so they hand out coins through promotions instead. Here is how each type works and what separates a fair offer from a thin one.
No-purchase sign-up bonus – Free Gold Coins and a few Sweeps Coins for registering and verifying your account. Worthwhile offers include at least a couple of SC with a 1x playthrough, since Gold Coins alone carry no prize value.
First-purchase deals – Optional packages that add bonus SC to your first order. A package that includes more Sweeps Coins than the dollars you pay adds real value, while one that simply matches the price adds none.
Daily login rewards – A free no deposit bonus that gives coins every 24 hours. The more useful versions pay some SC every day or grow with a login streak, while prize wheels that mostly land on Gold Coins add little.
Social media promotions – Giveaways, codes, and contests on Facebook, Instagram, and X. Regular contests with clear rules and several winners are worth entering. One-off posts with a single small prize rarely are.
Mail-in requests (AMOE) – Every sweepstakes site must offer a free way to get Sweeps Coins, usually a handwritten request sent by post. Follow the formatting rules exactly, since small errors can void an entry, and expect credits to take a few weeks.
Referral and VIP rewards – Coins for inviting friends and casino loyalty tiers for regular players. Check any spend a friend must make before your reward unlocks.
Why playthrough affects redemptions
Playthrough tells you how many times a Sweeps Coin must be wagered before prizes won with it can be redeemed. It is much lighter than real-money casino rollover: most South Dakota sweepstakes sites use 1x, so each coin only needs one wager.
Stake.us is the main exception, with a 3x playthrough on Stake Cash. Check this number in the sweepstakes rules before playing, because it affects how quickly you can reach a prize. Unfair bonus terms, judged against our Fair Gambling Codex, can lower a casino's Safety Index score.
Casino games you can play online in South Dakota
Deadwood's casino floors offer slots, blackjack, craps, roulette, and poker. Sweepstakes sites cover most of the same ground online, played with virtual coins instead of cash.
Slots
Most casino game libraries consist mainly of online slots, from classic three-reel titles to jackpot and bonus-buy games. Stake.us carries more than 3,000 slots, and Fortune Wins offers over 2,000 games. RTP varies by game, so check each title's info screen before you play.
Table games
Digital blackjack, real money roulette, and baccarat casino games are available at most sites, but the depth varies a lot. Stake.us has 30+ table games, while CrownCoins has none, so check the lobby if cards are your main interest.
Live dealer games
Via live casino streams, a real dealer will appear on your screen without the drive to the Black Hills. Stake.us covers blackjack, roulette, baccarat, and poker. Sportzino adds sic bo and game shows, and Real Prize runs six to eight tables.
Crash, Plinko, and other originals
Fast, simple games are a growing category. Stake.us builds its own Stake Originals in-house, and other sites carry crash games, Plinko, scratchcards, and fish games from third-party studios. These are especially popular at social casinos.

Not ready to claim coins yet? Play demo versions of popular slots and table games on our free casino games page, with no account or purchase needed.
Sweepstakes sites use everyday online payment methods to sell optional Gold Coin packages and to pay out prizes won with Sweeps Coins. Speed and minimums depend more on the method you choose than on the casino.
Debit and credit cards – The standard way to buy coins. Visa and Mastercard are accepted across our list, and some online casinos add Amex and Discover. Prizes rarely go back to a card, although Sportzino pays out to a Visa virtual card.
E-wallets – The most common payment method available at South Dakota casinos. At some sites, such as High 5, you must have bought coins with Skrill before you can redeem them. Usually Skrill casino payouts typically land within 1–2 days.
Bank transfers – This is the usual route for larger cash prizes and ACH casino transfers typically take 1–5 business days, and Fortune Wins pays out by ACH only, from $50.
Gift cards – Often the quickest way to claim a small prize, with minimums as low as 10 SC at Spinfinite. Delivery is usually instant or within a day of approval.
Cryptocurrency – Stake.us supports the most cryptocurrencies on our list (20+). You can often receive crypto casino payouts within hours once approved, but network fees apply.
Verifying your identity before a redemption
Every legitimate sweepstakes site checks your identity, referred to as Know Your Customer (KYC), before it pays a prize. The check confirms your age and that you are playing from an eligible state such as South Dakota.
Photo ID – Upload a clear color image of a valid South Dakota driver's license, state ID card, or US passport.
Proof of address – A recent utility bill, bank statement, or lease showing your name and South Dakota address. Many sites require it to be dated within the last three months.
Selfie check – Some sites ask for a live selfie or short video scan to match your face to your ID.
How to sign up in South Dakota in five steps
Opening an account takes a few minutes. These steps get you set up and ready to claim your free coins.
Five steps to casino setup
Choose a recommended site: Pick a casino from our list with a Safety Index of 7.5 or higher and confirm it accepts South Dakota.
Register: Enter your name, email, date of birth, and home address. Sites set a minimum age of 18 or 21.
Verify early: Upload your ID and proof of address now, so your first redemption is not held up later.
Claim the free coins: Collect the no-purchase bonus and your first daily reward. You do not need to buy anything.
Set limits: Decide on a time and spending limit, and use the site's own tools to stick to it.
If you wish to try a sweepstakes casino, sign up at one of the recommended sites above, or browse the newest sweepstakes casinos we have reviewed.
Sweepstakes apps for iPhone and Android
Most sites on our South Dakota list run well in a mobile browser, and several also offer native mobile casino apps. Apps tend to load faster and make daily rewards easier to collect.
Whether you use an app or a browser, expect to turn on location services. Sites use geolocation to confirm you are in an eligible state like South Dakota before you can play with Sweeps Coins.

Upsides and drawbacks for South Dakota players
With no online casinos licensed in the state, sweepstakes sites are the main way to play casino-style games online in South Dakota. Here is how they compare with a trip to Deadwood or a tribal casino.
✅ Pros
❌ Cons
Play anywhere in the state – From Sioux Falls to Rapid City, with no drive to Deadwood or a tribal casino.
No real money wagering – All play uses virtual coins and only Sweeps Coins can be redeemed for prizes.
Free to play – Every site offers a no-purchase way to get Sweeps Coins, so buying coins is always optional.
No state oversight online – Sweepstakes sites sit outside the Commission on Gaming's licensing system.
Games beyond the casino floor – Crash games, Plinko and thousands of slot titles you will not find in Deadwood.
Redemption hurdles – ID checks, cash minimums of up to 100 SC, and bank transfers that can take several days.
Prizes you can redeem – You can exchange Sweeps Coin winnings for gift cards or cash once you meet the playthrough requirement.
No mobile sports betting – Sports bets stay in person only after the 2026 ballot plan was rejected.
Staying in control while you play
Sweepstakes play can feel low stakes because the coins are virtual, but optional coin purchases are real spending. Treat any purchase as entertainment, not a way to win, and take a break if it stops being fun.
Age limits – Deadwood casinos, tribal casinos, and video lottery require players to be 21. Lottery tickets are 18+, and sweepstakes sites set their own minimum of 18 or 21.
Site tools – Use the purchase limits, session reminders, cool-off periods, and self-exclusion options in your account settings.
South Dakota help – The state helpline, 1-888-781-HELP (4357), is printed on lottery tickets and video lottery terminals and connects callers with Gamblers Anonymous groups near them.
Deadwood self-exclusion – The Commission on Gaming keeps a voluntary exclusion list for Deadwood casinos. Tribal casinos run their own programs, so ask at the venue.
National help – Call or text 1-800-MY-RESET (1-800-697-3738), the National Council on Problem Gambling's 24/7 confidential helpline.
Report fake sites – Contact the Commission on Gaming at (605) 578-3074, or the Attorney General's consumer protection line at 1-800-300-1986 (in state) or (605) 773-4400.
South Dakota's in-person casinos are split between historic Deadwood in the Black Hills and tribal venues run by nine tribes.
Games include slots, blackjack, craps, poker cash games, roulette, and keno. Many venues take in-person sports bets, and Deadwood's maximum bet is $1,000. All require players to be 21.
Deadwood
The former gold-rush town has hosted legal gaming since November 1989, with part of the tax revenue going to historic preservation. At the end of fiscal year 2025, it had 136 active retail gaming licenses and 2,696 licensed gaming devices. Casinos there generated $147.75 million in adjusted gross revenue and paid about $13.1 million in gross revenue tax, plus $5.5 million in device fees. Seven Deadwood casinos were taking sports bets in June 2026.
Royal River Casino & Hotel, Flandreau

How winnings and prizes are taxed in South Dakota
South Dakota has no personal income tax, so the state does not tax gambling winnings or sweepstakes prizes. Federal tax still applies to both.
No state tax – There is no South Dakota income tax return to file for gambling winnings or redeemed prizes.
Federal income – Casino winnings and redeemed Sweeps Coin prizes, whether cash or gift cards, count as taxable income on your federal return.
Reporting thresholds – From January 1, 2026, casinos issue a Form W-2G for slot, bingo, and keno wins of $2,000 or more. Sweepstakes sites may issue a Form 1099-MISC once your prizes from one site reach $2,000 in a year.
Loss deductions – If you itemize, from the 2026 tax year you can deduct gambling losses up to 90% of their value, and never more than your winnings. A House committee voted in September 2026 to repeal the 90% cap, but that change is not yet law.
Professional advice – We cannot give legal advice and tax rules change often, so speak to a certified public accountant (CPA) or tax professional about your own situation.
