Winning money from gambling or the lottery in Hawaii feels exciting, but it also comes with tax rules you can’t ignore. You have to pay both federal and Hawaii state taxes on gambling and lottery winnings, no matter the amount. Whether you hit a scratch-off, score a casino jackpot, or get lucky in a multi-state lottery, that money counts as taxable income.
Federal withholding kicks in right away, and Hawaii adds its own state income tax on top. The exact amount depends on your winnings, your total income, and whether you take a lump sum or annuity. A calculator helps you figure out what you’ll actually keep after taxes, so you don’t get blindsided.
Knowing how to report your winnings, which forms you need, and whether you can deduct losses makes the process less stressful. Understanding these rules before tax season can save you headaches and possibly some money.
Hawaii taxes gambling and lottery winnings as regular income, no matter if you win from games played in the state or somewhere else. You also have to deal with federal taxes, and your residency status affects what gets taxed. If you want to avoid penalties, you need to understand how withholding and estimated tax payments work.
All money or prizes you win from gambling count as taxable income in Hawaii. This covers casino games, poker, sports betting, fantasy sports, raffles, and lotteries. Even if you gamble online or out of state, Hawaii law says you have to report those winnings on your state return.
Non-cash prizes get taxed too. If you win a car, vacation, or electronics in a raffle or contest, you must report the fair market value. Hawaii doesn’t let you leave these items off your taxable income.
Hawaii doesn’t have legal casinos or sportsbooks right now. Still, if you win in Las Vegas or anywhere else, Hawaii wants you to report it. So, your gambling activity is always on the table for taxes, no matter where it happens.

The IRS taxes all gambling winnings. You have to report every dollar you win, whether it’s from slots, lottery tickets, or sports bets. The IRS only lets you deduct gambling losses up to the amount you won.
Hawaii mostly follows suit, but with tighter rules. You can no longer offset winnings with losses for state taxes – you have to report the full amount you win, even if you lost more overall. That’s a heavier state tax burden for frequent gamblers.
For example:
So, you really need to track your winnings separately for federal and state returns.
If you live in Hawaii, you have to report all income, including gambling winnings earned in other states or even other countries. If you hit the lottery in California or win at a Nevada casino, Hawaii still taxes those winnings.
Nonresidents get a bit of a break. Since Hawaii doesn’t have casinos or a state lottery, nonresidents usually don’t owe Hawaii tax on gambling winnings unless they have another taxable source in the state.
If you move to Hawaii during the year, you become a part-year resident. In that case, you must report winnings earned after you establish residency. Keep good records of dates and amounts to file correctly.
When you win a big prize, federal law might require automatic withholding. For example, lottery jackpots or casino wins above certain amounts trigger a 24% federal withholding. Hawaii doesn’t have its own withholding system for gambling, so you have to pay your state taxes yourself.
If your winnings aren’t subject to withholding, you might need to make quarterly estimated tax payments. This kicks in if you expect to owe at least $500 in state tax or $1,000 in federal tax after credits and withholdings.
If you don’t pay enough during the year, you could face penalties. To avoid that, estimate your winnings and put money aside for both federal and state taxes. Many folks use tax calculators to help with this before filing.
You have to report gambling winnings to both the IRS and the Hawaii Department of Taxation. Federal law says you must pay income tax on all gambling income, and Hawaii taxes winnings as part of your state income. What you owe depends on how much you win, where you win, and if you can deduct losses.
Yes. Hawaii treats gambling winnings as taxable income, just like wages or interest. This includes lottery prizes, casino payouts, sports bets, and online gambling income.
Hawaii lets you deduct gambling losses up to your winnings, in line with federal rules. For example, if you win $2,000 but lose $1,200, you only pay Hawaii income tax on $800.
Hawaii’s income tax rates range from 1.4% to 11%, depending on your total taxable income. The more you earn, the higher your rate on those winnings.
Unlike some states, Hawaii taxes all gambling income, so even small wins go on your Hawaii return. You can find more info and forms on the Hawaii Department of Taxation website.
Hawaii doesn’t have a special tax rate for gambling. Winnings just get added to your regular income and taxed under the state’s progressive system.
Your gambling income combines with wages, retirement income, or business earnings to determine your tax bracket.
No flat percentage or special withholding applies to gambling at the state level. Still, casinos or lottery operators outside Hawaii might withhold federal tax before paying you.
Since Hawaii has no casinos or lottery, most winnings come from out-of-state or online. You still need to report them on your Hawaii return. For filing, you’ll want to check the official Hawaii tax forms and instructions.
Casinos, sportsbooks, and lotteries issue Form W-2G when your winnings hit certain levels, like $1,200 from slots or $5,000 from poker tournaments. Other gambling income might show up on a 1099-MISC or 1099-K if paid electronically.
These forms go to you and the IRS. Even if you don’t get a form, you still have to report all gambling winnings on your tax return.
Hawaii doesn’t have its own W-2G. You just use the federal form when you do your state return. Keep solid records of your wins and losses in case the state asks questions.
Yes. If you get cryptocurrency payouts from gambling platforms, both the IRS and Hawaii see them as taxable income. The fair market value of the crypto when you get it counts as your winnings.
Later, if the value changes and you sell or trade the crypto, you might trigger capital gains or losses. Keeping good records is important here.
Promo credits, free bets, or bonuses become taxable once you turn them into real money winnings. For example, if you use a $50 free bet and win $200, you have to report the $200.
Federal and state law require you to report these amounts even if you don’t get a tax form from the gambling site.
Hawaii doesn’t allow legal casinos, sports betting, or lotteries, but if you live in Hawaii, winnings from other states or countries are still taxable. You also pay federal tax on all gambling income, and withholding might apply depending on how much you win and where you claim it.
Hawaii taxes all gambling winnings as regular income. Your prize gets added to your yearly earnings and taxed using the state’s progressive brackets.
For 2025, state rates range from 1.4% to 11%. The lowest bracket is for small incomes, while the 11% top bracket kicks in after $200,000 (single) or $400,000 (married filing jointly).
You can’t exclude gambling income from Hawaii taxes, and there aren’t special deductions beyond what all taxpayers get. If you itemize, you can deduct gambling losses, but only up to your reported winnings.
Because Hawaii’s top state income tax rate is among the highest in the country, your net winnings can really shrink if you’re in the upper brackets. Using a gambling tax calculator can help you estimate what you’ll owe. You might want to check the Hawaii Department of Taxation FAQs for more details.
Hawaii doesn’t have separate local or city income taxes. Unlike places like New York City, Hawaii’s system is all state-level.
Your gambling winnings get taxed under the state’s progressive income tax plus federal tax. You don’t have to worry about extra county or municipal surcharges.
General excise taxes might apply to businesses, but not to individual gambling winnings. For individuals, it’s pretty simple: your gambling winnings get taxed under Hawaii’s state income tax rules, no extra local layer.
At the federal level, gambling winnings above certain amounts trigger automatic withholding. The payer, like a casino or lottery, must withhold 24% federal tax when your win exceeds:
Hawaii doesn’t require state withholding since there aren’t legal gambling operations in the state. But if you win in another state, that state might withhold its own tax before paying you.
You still have to pay Hawaii state income tax when you file, even if no withholding happened. A gambling tax calculator can help you see what was withheld and what you’ll ultimately owe.
If you win a big lottery prize outside Hawaii, you might have to choose between a lump sum or annuity payment. The choice affects your taxes at both federal and state levels.
A lump sum gives you the money all at once, but it pushes all the income into one tax year. That usually puts you in the highest federal bracket (up to 37%) and Hawaii’s top bracket (11%).
An annuity spreads payments out over years. Each payment gets taxed as income for that year, which might keep you in a lower bracket depending on your other earnings.
While annuities lower your immediate tax hit, they also limit your access to the cash. A tax calculator can help you compare the after-tax value of both options before you make up your mind.
Let’s see how taxes actually play out for Hawaii residents with three real-life examples:
Example 1 – Small Win ($1,000 slot win in Nevada):
Example 2 – Big Win ($50,000 poker prize in California):
Example 3 – Jackpot ($1,000,000 lottery win in New York, lump sum):
Honestly, a gambling tax calculator is your best friend for quick estimates. Don’t forget both federal and Hawaii state taxes when you’re figuring out what you’ll actually keep.
You have to report all gambling and lottery winnings on your federal and Hawaii state tax returns. Even if you never get a tax form, federal law still makes you report the income – and Hawaii does too. Keeping records and using the right forms keeps you out of trouble. For Hawaii tax info and forms, check the Hawaii Department of Taxation Forms page and the IRS Forms & Instructions page.
Casinos, lotteries, or other payers might send you Form W-2G if your win is big enough (like $1,200+ from slots). If you win a non-cash prize, like a trip, you could get a Form 1099-MISC.
Report your gambling income on Form 1040. You’ll list winnings on Schedule 1, Additional Income and Adjustments to Income, which then feeds into your main return.
If you itemize deductions, you can use Schedule A to claim gambling losses, but only up to your winnings. You can’t deduct more than you won, and you’ll need detailed proof for each gambling session.
Hawaii treats gambling winnings as regular income. If you’re a full-year resident, use Hawaii Form N-11. Nonresidents go with Form N-15. Find both at the Hawaii Tax Forms site.
Put your gambling winnings in the “Other Income” section of the return. Hawaii doesn’t let you deduct gambling losses, even if you itemize federally. So, your Hawaii tax bill could be higher if you had big losses.
Hawaii taxes all income you earn as a resident, no matter where you win. If you live in Hawaii and win the lottery in another state, you still owe Hawaii income tax on that prize.
Your Hawaii return is due the same day as your federal one: April 15 (or the next business day if that’s a weekend or holiday). If you need more time, file Form N-101A for an automatic 6-month extension by the original due date. Here’s the official Hawaii extension form.
An extension gives you more time to file, but not to pay. You need to pay any estimated tax by April 15 to avoid penalties and interest. Pay online via the Hawaii Tax Online system, by check, or electronic funds transfer.
If you expect a big balance from gambling wins, making an estimated payment ahead of time can help cut down on penalties.
Keep a gambling log that lists the date, location, type of wager, amounts bet, and what you won or lost. The IRS expects you to have detailed proof if you claim losses.
Hang onto tickets, receipts, and payout slips from casinos or lotteries. If you gamble online, download your betting history. Bank statements showing deposits and withdrawals also help back up your records.
Good records make it much easier to report your winnings and claim deductions. Without proof, you can’t deduct losses on your federal return, and you might face penalties or an audit.
You still have to report gambling and lottery winnings on your tax return, even if you don’t get a Form W-2G. Both the IRS and Hawaii treat these as taxable income, and you’re responsible for keeping records and paying any tax you owe.
Casinos, sportsbooks, and lotteries only send a W-2G form if your winnings hit certain levels. For example:
If your win doesn’t meet these numbers, you probably won’t get a form.
Sometimes, an ID mismatch is to blame. If your Social Security number or taxpayer ID doesn’t match IRS records, the casino might withhold taxes but not generate a W-2G.
Hawaii’s reporting rules usually match the federal ones, so the same issues pop up. Even if you never get the form, you still have to report all winnings on both your federal and state returns.
If you don’t get a W-2G, you’ll need to rely on your own records. Keep player club statements, betting slips, sportsbook account histories, and bank transaction records. These help you figure out the total winnings you need to report.
List gambling winnings as “Other Income” on your Form 1040. You can only deduct losses if you itemize, and only up to your winnings.
For Hawaii, include the same winnings on your Form N-11. The state expects you to report everything, with or without a W-2G.
Organizing your records by date and game type makes life easier if the IRS or Hawaii Department of Taxation ever asks questions.
If you think you should’ve received a W-2G form but didn’t, just ask. Contact the casino, sportsbook, or lottery office and give them your name, Social Security number, and details (date, amount, etc.).
Casinos keep payout records for wins that meet reporting limits. They can reissue a W-2G or give you a statement of winnings and taxes withheld.
For online sportsbooks or betting apps, you can usually download tax forms from your account. If you can’t find them, reach out to customer support.
Requesting a copy helps make sure your records match what the IRS has, which can help you avoid mismatches or audits.
If you had big winnings and no taxes were withheld, you might need to make quarterly estimated tax payments. The IRS expects this if you think you’ll owe at least $1,000 for the year after credits and withholding.
Pay through IRS Direct Pay or by filing Form 1040-ES. For Hawaii, use Form N-200V to send estimated payments.
Skipping estimated payments can lead to underpayment penalties. Even if you plan to settle up at tax time, the IRS and Hawaii may charge interest if you pay late.
Paying as you go helps you dodge penalties and keeps you from getting hit with a big surprise bill later.
Hawaii lets you deduct gambling losses, but there are some strings attached. You’ll want to understand how the deduction works, what records you’ll need, and the limits, so you don’t end up paying more than you should – or less, which could cause problems later. See official details at the Hawaii Department of Taxation and the IRS Gambling Winnings/Losses page.
You can only deduct gambling losses in Hawaii if you itemize. If you take the standard deduction, losses don’t help you at all.
For a lot of people, the standard deduction is bigger than their itemized deductions. In that case, itemizing just to claim gambling losses probably won’t lower your tax bill.
Here’s a quick comparison:
Filing Status | 2025 Standard Deduction (Federal) | Itemizing Needed for Gambling Losses? |
---|---|---|
Single | $14,600 | Yes |
Married Joint | $29,200 | Yes |
Hawaii mostly follows the federal rules. You’ll need to see if your itemized deductions, including gambling losses, are bigger than your standard deduction before deciding.
You can only deduct losses up to the amount you report as winnings. If you win $2,000 but lose $3,500, you can only deduct $2,000. The leftover $1,500 can’t be claimed or carried over.
This rule stops you from using gambling losses to offset other income, like your salary or business profits. Deductions only reduce gambling income – not your whole taxable base.
Example:
This cap applies whether you gamble once in a while or all the time. It’s a key limit to know before you file.
The IRS and Hawaii both expect you to keep accurate records for your gambling losses. Estimating or rounding isn’t allowed.
What counts as proof?
Your gambling diary should list dates, locations, game types, amounts wagered, and your results. If you don’t have this documentation, you can’t claim the deduction – even if your losses were real.
Remember, casinos might issue Form W-2G for big wins, but they don’t track your losses. The burden of proof is all on you.
Most people are casual gamblers. In that case, you report your winnings as “other income,” and you can only claim losses if you itemize deductions.
Professional gamblers report both winnings and losses as business income on Schedule C. They can deduct ordinary business expenses. But since 2018, they can’t deduct losses beyond their winnings.
To be considered a professional gambler, you have to prove gambling is your main trade or business. That means showing things like how much time you spend, how regularly you play, and your intent to make a profit. It’s not easy to qualify.
For most Hawaii residents, casual gambler rules apply. Unless you can prove gambling is your livelihood, you’ll fall under the itemized deduction rules.
Hawaii treats gambling and lottery winnings as regular income. You need to report all your winnings, whether they’re from scratchers, raffles, or casino-style games. Federal and state tax rules both apply. How much you keep depends on where you live, how big your prize is, and how you choose to get paid.
Hawaii residents pay state income tax on all gambling winnings, even if the prize comes from another state. Hawaii doesn’t exempt lottery or casino winnings from taxation.
Nonresidents pay Hawaii tax on winnings earned in Hawaii. So, if you visit and win a local raffle or charity game, you have to file a Hawaii state return. See the Hawaii Department of Taxation for forms and details.
Hawaii doesn’t have its own lottery. Still, if you buy tickets in other states or online, you must report your winnings. The IRS usually withholds 24% from big prizes, but Hawaii may not withhold anything upfront. You’ll pay when you file your state return.
Small wins under $600, like scratch-off prizes, usually get paid out by retailers without tax paperwork. But you still have to report these as income on your federal and state returns.
For bigger prizes, the payer issues a Form W-2G. This form shows your winnings and any taxes withheld. If there’s no state tax withheld, you still owe it at tax time.
Jackpots in the thousands or millions almost always trigger federal withholding. Hawaii residents add the full amount to their state return. You can’t offset losses against winnings for Hawaii taxes – the entire prize counts as taxable income.
If you win a multi-state lottery while living in Hawaii, you can pick a lump sum or annuity payout. Each affects your taxes differently.
Getting a lump sum gives you immediate cash but a bigger tax bill upfront. An annuity spreads out both your income and your tax, which can help with planning. Your choice really depends on your financial goals and how you want to handle taxes.
If you give someone a lottery ticket as a gift and they win, the prize belongs to whoever redeems it. You can’t claim ownership for tax reasons later.
If you split a prize with friends or family, the IRS usually wants each person to report their share separately. This keeps one person from getting taxed on the whole thing.
Large gifts can trigger federal gift tax rules if they’re over the annual limit. Hawaii follows federal guidelines here, so keep records of any shared or gifted winnings. Written agreements help avoid arguments and clear up tax obligations for everyone. Check the IRS Gift Tax page for details.
If you share a winning ticket, both the IRS and Hawaii Department of Taxation expect you to report things accurately. The way you file determines if everyone pays their share or if one person gets stuck with the whole tax bill. Good paperwork avoids headaches and penalties.
If you buy a ticket as a group, use IRS Form 5754 when you claim the prize. This tells the lottery agency that more than one person owns the ticket. If you skip it, the prize might get reported under just one name.
List each person’s share, Social Security number, and address on the form. The lottery agency then issues separate W-2G forms to each winner. That way, the IRS and Hawaii know who gets what.
Fill out Form 5754 before you submit your claim. It’s much harder to fix mistakes after the payout. Keep a copy for your records in case of an audit. You can find Form 5754 on the IRS website.
When a group wins, each member should get their own W-2G tax form. This shows their share and any taxes withheld. The IRS needs this because gambling income is reported individually.
If four people split $100,000 evenly, each should get a W-2G for $25,000. Federal withholding of 24% applies if your share is over $5,000. Hawaii state income tax also applies.
If the lottery agency issues just one W-2G to one person, that person is on the hook for all the tax. Using the right forms keeps everyone’s tax liability fair.
If you’re buying tickets as a group, make a written pool agreement. List the members, how much each person put in, and how you’ll split winnings. Even a short, signed note helps.
A clear agreement cuts down on disputes if you win. It also proves to the IRS and Hawaii tax authorities that the prize belongs to multiple people. Without it, one person might be treated as the only winner.
Simple records – dated emails, payment receipts, or a signed note – make tax reporting easier. This protects your money and your friendships.
Sometimes, only one person redeems a winning ticket bought by a group. Then, the lottery agency issues the W-2G in that person’s name, making them look like the only winner.
To fix this, the named winner reports the full prize on their tax return. They use Form 5754 and Form 1099 to show the IRS how the money was split. Each person then reports their own share as income. You can get these forms at the IRS Forms page.
This can be stressful, since the first winner is responsible for reporting and withholding. It’s always easier to get it right from the start, but if you mess up, you can still fix it with the right paperwork.
If you win a multi-state lottery like Powerball or Mega Millions, you might owe taxes to more than one state. Federal tax always applies, but the state where you bought the ticket and the one where you live both matter.
If you buy a winning ticket in another state, that state usually gets first crack at taxing your prize. For example, if you live in Hawaii but buy a ticket in California, California law applies.
Each state has its own rules. Some, like Florida or Texas, don’t have income tax, so you don’t pay state tax there. Others, like New York or New Jersey, withhold a chunk before you even get your check.
You might need to file a nonresident tax return in the state where you bought the ticket. This makes sure you pay the right amount before dealing with your home state. Always check the purchase state’s withholding rate and filing rules. You can get state forms from the IRS State Government Websites directory.
If you pay tax to the state where you bought the ticket, your home state might give you a credit so you don’t get taxed twice. This credit reduces your Hawaii tax by what you already paid elsewhere.
To claim the credit, you usually need to:
Credits aren’t always dollar-for-dollar. If Hawaii’s tax rate is higher than the purchase state’s, you pay the difference. If it’s lower, the credit gets capped at Hawaii’s rate.
If you pick the annuity option, you don’t pay tax on the whole jackpot at once. Instead, each annual payment is taxable the year you get it. Both the purchase state and Hawaii may want a cut each year.
Keep records of every payment. The IRS and state agencies issue a Form W-2G every year, showing your taxable amount and any withholding.
When payments stretch out for decades, tax rates can change. Your tax burden might shift over time. Careful recordkeeping helps you avoid double taxation and keeps things straight if state rules change.
Some states have reciprocity agreements to make tax reporting easier for people earning income across state lines. These are more common with wages than lottery winnings, but sometimes they apply.
Usually, you’re a nonresident in the purchase state and get taxed by their rules. Your home state (Hawaii) then taxes you as a resident but may give you a credit for taxes paid elsewhere.
Hawaii doesn’t have reciprocity agreements for lottery income. If you live in Hawaii and win in another state, you have to follow both Hawaii’s resident tax rules and the purchase state’s nonresident requirements. Always check both states’ instructions before you file. Hawaii forms and instructions are at the Hawaii Department of Taxation Forms page.
Not reporting gambling winnings can lead to penalties, interest, and even audits. The IRS and Hawaii tax authorities track gambling income, and ignoring the rules can make your bill a lot bigger.
The IRS charges separate penalties for filing late and paying late. If you miss the filing deadline, the failure-to-file penalty is usually 5% of the unpaid tax per month, up to 25%. This is often the bigger penalty, so it’s better to file even if you can’t pay right away.
If you file on time but don’t pay, the failure-to-pay penalty is 0.5% per month, also capped at 25%. Interest piles up daily on top of these charges.
For example, if you owed $2,000 in taxes on unreported winnings and filed three months late, you’d face a $300 late filing penalty plus interest. Filing on time and arranging payment helps lower your penalties. For more info, see the IRS Penalties page.
Casinos, lotteries, and other payers issue Form W-2G or 1099-MISC for gambling winnings. The IRS matches these forms to your return electronically. If you leave off winnings, you’ll probably get an automated notice.
Hawaii’s Department of Taxation checks federal data to confirm you’re following state rules. If your federal return shows gambling income but your Hawaii return doesn’t, you might get a notice from the state.
If you ignore notices, things can get worse. Repeated mismatches or big unreported amounts might trigger an audit. The IRS and Hawaii can ask for bank records, betting slips, and other proof. Keeping good records makes it way easier to respond if you get questioned.
If you realize you left out some winnings, you can fix it by filing an amended return with Form 1040-X. This form lets you update your income and pay any extra tax you owe. Getting ahead of the IRS and filing before they reach out usually means you’ll face fewer penalties. You can grab Form 1040-X and instructions straight from the IRS Form 1040-X page.
If you just can’t pay the full amount, you can ask for an installment agreement. The IRS offers monthly payment plans, but you’ll keep seeing interest and some small penalties until you’ve paid everything off. Here’s where you can apply for a payment plan: IRS Payment Plan Application.
Hawaii also lets you set up payment arrangements for state taxes. If you reach out to both the IRS and Hawaii Department of Taxation early, you show you’re trying to do the right thing. That can help you avoid bigger problems like wage garnishment or liens. For Hawaii forms and guides, check the Hawaii Department of Taxation Forms page.
If you get a notice, owe a big balance, or the IRS starts talking about an audit, it’s usually smart to call a tax pro. An enrolled agent, CPA, or tax attorney can look over your records, talk to the IRS for you, and help work out payment terms.
Tax professionals also know how to handle state tax issues. Hawaii’s Department of Taxation can hit you with its own penalties, and a pro can make sure your federal and state returns line up.
If you’ve got a few years of unreported winnings, a tax professional can walk you through voluntary disclosure or streamlined filing. That can lower your risk of criminal charges, which nobody wants to mess with.
Yep, Hawaii taxes gambling winnings as part of your state income tax. Unlike Nevada, where gambling income might not get taxed, Hawaii treats your winnings just like regular income.
If you win $5,000 at a Vegas casino or from an online lottery, you still have to report it on your Hawaii return. The state taxes that income at your usual rate, which goes from 1.4% up to 11%.
Hawaii residents get taxed on all their income worldwide, not just what comes from inside the state. Even though gambling’s illegal in Hawaii, your out-of-state or online winnings are still fully taxable here. Here’s more on Hawaii income tax: Hawaii Tax Department FAQ.
Hawaii doesn’t have a separate gambling tax. Instead, winnings just get lumped into your gross income and taxed under the state’s regular progressive income tax rates.
Say your taxable income lands you in the 8.25% bracket. Your gambling winnings get taxed at that same rate. There’s no special flat gambling tax
Yes, you can use online lottery or gambling tax calculators that factor in Hawaii’s state income tax rates. These tools mix in both federal and state rates, so you get a quick estimate of your after-tax winnings. If you want to check the latest tax brackets or find official forms, you should visit the Hawaii Department of Taxation and the IRS website for details straight from the source.
