Gambling Win Rate
Before December 31, 2017, the standard withholding rate was 25 percent and the backup rate was 28 percent. The $5,000 threshold applies to net winnings, meaning you deduct the amount of your wager. The standard odds you can encounter for any 5-card hand are 0.0015% (Royal Flush), 0.14% (Full House), 0.196% (Flush), 4.75% (Two Pair) and 50.1% at High Card only. Now, it’s up to you whether you want to take the risk and rely on fate, or you choose to go with the safest alternative.
The answer is yes, but the good thing about gambling tax law for big winners is that, unlike income taxes, gambling taxes are not progressive. Whether you win $1,500 at the slot machine or $1. How much are my gambling winnings taxed in Indiana? Effective for tax years after 2017, the federal rate on winnings over $5,000 is 24%. Winnings under that benchmark of $5,000 must also be reported depending on their amounts and sources. Currently, Indiana’s personal income tax rate is 3.23%. Almost all gambling winnings are subject to this tax.
The house edge at slot machines isn't based on how lucky the players are, it is based on the pre-programmed electronic software used. And, that house edge varies from casino to casino and from geographic location and state to state.
Don't be fooled by a billboard that says 'Our slots pay 99%' because that only pertains to a small number of machines, not the casino's overall house edge. All video slot machines (including poker) use a Random Number Generator to provide accurate odds for the player and the house.
The number of winning hands (symbols) in any program is mathematically proven before the slots hit the gaming floor, and while the odds vary for each player (because this really is gambling), overall, the anticipated house edge will eventually be achieved.
The House Edge at Slots
Each gaming jurisdiction requires all slot machines to be registered and all slot manufacturers must submit their programming and math charts to the state gaming office, such as the Nevada Gaming Control Board. While the state may only require a minimum payback of 86-percent, most video poker and slot machines pay more. The average payback in Nevada is lowest on penny slots at about 90-percent. Dollar slots and some Deuces-Wild poker machines have the highest payback at nearly 99-percent.
Of course just because a machine has a payback of 99 percent does not mean you will win back $99 for every $100 you play through the machine. That payback amount is an average. Over the course of an evening of gambling, you might lose $500 or win $5,000. That's the beauty of the gamble, right? And, the casino doesn't care either way, because they win an average of whatever their house edge is over the course of the month.
How does that 99-percent work for you? Aside from the ups and downs of jackpots and dry spells, your entertainment dollar is going to be based on how long you play. If you play a machine that takes $3 per spin and you pull the handle 10-times an hour, you are playing $3 x 10 x 60 = $1,800 in action. At 99-percent house edge, your play costs $18 an hour. Some nights you'll go home ready to kick the wall, and other nights you be singing a happy tune because you hit a jackpot and skated out with hundreds. That's gambling.
Play Within Your Means
As a general rule, the higher denomination slot machines have a greater overall payback percentage that the lower ones. That's great for those with a healthy bankroll, but you'll need to play the games that offer you the best bang for the buck. The worst thing a player can do is to play any game for more money than they can afford to lose or at a higher denomination than their bankroll will handle.
Another consideration is making sure you can qualify for any bonus screen or Royal Flush payoff. If you want to wile away the hours playing a single nickel in a machine, that's great. Enjoy. You won't win or lose much and you'll probably go home happier than most players. But your play comes with a catch!
That catch is that the house edge provided for each machine includes the big jackpots (such as a Royal Flush), and if you play below the minimum to reach the bonus screen, the house edge is much higher! You won't lose much, but you'll never win more than a couple of dollars.
The Best Option
The best option is to play the games you enjoy most, and make sure you read the Help Screen so you know how many credits it takes to qualify for at least the lowest progressive jackpot and the bonus screen (or Royal Flush at video poker). As a recreational player, your first goal is to have fun. If you only visit the casino occasionally the overall payback of the machine won't make much of a difference. If you visit regularly, make sure you join the Player's Club and play within your means!
So you’ve won a jackpot on the slots or defied the odds on a sports bet in Indiana. Other than bragging on social media, one of the next things you have to do is give the federal and state governments their cut.
Winnings from all forms of gambling are taxable income, including winnings from:
- Lottery
- Slots
- Table games
- Sports betting
- Horse racing
Even if you put money down and win an organized Rock-Paper-Scissors competition, you have to pay taxes on the winnings. Even non-cash prizes like merchandise have to be reported on your federal and state income tax returns.
The idea that the Internal Revenue Service and the Indiana Department of Revenue won’t know is folly. The parties which pay out the prizes, whether that be casinos, sportsbooks, whatever, keep receipts and report them.
How much are my gambling winnings taxed in Indiana?

Effective for tax years after 2017, the federal rate on winnings over $5,000 is 24%. Winnings under that benchmark of $5,000 must also be reported depending on their amounts and sources.
Currently, Indiana’s personal income tax rate is 3.23%. Almost all gambling winnings are subject to this tax.
Casinos typically withhold 25% of your winnings for tax purposes. That is only the norm if you provide them with your social security number, however. If you decline that option, they usually withhold 28%.
How to determine if your winnings are taxable income
Another service the casinos usually provide for mutual benefit is sending you the appropriate paperwork. Fortunately, Indiana allows you to fill out the same form for both purposes.
Form W-2G, Certain Gambling Winnings reports your winnings for the year to both the IRS and you, in case you haven’t been keeping track.
The amount on this form will include any winnings from the year which qualify for federal taxes. That total will consist of:
- Your winnings (not reduced by the wager) of at least $1,200 from a bingo game or slot machine
- The winnings (reduced by the wager) of at least $1,500 from a keno game
- Your winnings (reduced by the wager or buy-in) of at least $5,000 from a poker tournament
- The winnings (except winnings from bingo, slot machines, keno, and poker tournaments) reduced, at the option of the payer, by the wager are $600 or more, and at least 300 times the amount of the bet
- Your winnings that are subject to federal income tax withholding (either regular gambling withholding or backup withholding)
How to report your gambling winnings to the IRS
The IRS requires you to report the total of your all qualifying gambling winnings for the year on a Form 1040. If you get the W-2G from the payers of your winnings, it’s a simple process of adding up those winnings and the amount of tax they withheld and then transferring those totals onto the 1040.
Add up all the numbers from Box 1 on the W-2G forms and separately, calculate the sum of all the numbers from Box 2. Place the Box 1 total on line 21 of the 1040 and place the Box 2 sum on the line designated as federal income tax withheld.
Even if the game operator didn’t do its job and you didn’t receive a W-2G, that doesn’t mean you’re off the hook.
You are still required to report all your gambling winnings from the year on the form 1040. To do that, fill out Schedule 1 with your gambling winnings as “Other Income.” Attach that to Form 1040 and include it in your personal income tax return.

So what if you weren’t flying solo, but pooled your resources together with others to maximize your chances of winning it big? That doesn’t change much.
Paying taxes on a shared prize
The IRS is prepared for this scenario. Form 5754is your go-to.
This is the form to use when you receive gambling winnings, not in your name on a W-2G. This form is also appropriate when you’re part of a group of two or more people sharing winnings.
The important thing to remember is that Form 5754 should not be included in your income tax return. Fill it out and give it to the person who received the W-2G.
Keep a copy for your records. The person who received the initial W-2G should submit all the appropriate 5754s back to the casino so they can correctly record the transaction.

The casino will then send each person their own W-2G. From there, the process is identical to how you would report any individual winnings.
How to report your gambling winnings to Indiana
As previously stated, Indiana is a state that allows you to use Form W-2G for your state income tax return as well. To do so, transfer the amount from Line 7 of your Federal 1040 to Line 1 of your IT-40.
If all or part of your winnings came while you were outside of the Hoosier State, you still must report them. That includes winnings from multistate lotteries. Report them just as you would if they came from an in-state game.
There is one legal way to reduce your tax liability from gambling winnings. It only applies if you opt to itemize your deductions, however.
Indiana and IRS gambling deductions for taxes
The IRS does allow a deduction for gambling losses. It cannot be claimed if you take the standard deduction on your return, however.
For those who itemize, gambling losses go on Line 28 of Schedule A, Form 1040. You cannot claim a deduction larger than your reported winnings.
And just because you deposit more than you withdraw from your bank account is not necessarily sufficient evidence. You must prove your losses.
You also cannot deduct expenses incurred along the way. The cost of your hotel and meals are just part of the necessary out-of-pocket expense.
If you opt to itemize and claim gambling losses, you’re better off keeping the following for your records:
Bet Win Rate
- The date and type of each wager
- Where you placed the bet, i.e., the name of the casino
- How much you won or lost
- Wagering tickets
- Canceled checks
- Credit card records
Gambling Win And Loss How To Report
Casinos can make this easy for you as well. If you’re part of their rewards programs, getting an annual summary of your gambling losses is quite simple.
Gambling Win And Loss For Tax
The same goes for any winnings from the latest gambling option, legal sports betting in Indiana.
Taxes on sports betting winnings
With legal sports betting new to Indiana, there are plenty of people betting on college football and the NFL. Your parlay on Notre Dame football or Purdue football games is also taxable income if it exceeds $600. It doesn’t matter whether you placed your wager at an Indiana online sportsbook, inside a casino, on a kiosk at an off-track betting site or on your phone from your couch.
Just like other types of gaming operators, the book you placed your bet with should send you a W-2G. You can use that to report your winnings and withholdings to both Indiana and the IRS.
The positive side of that is just like any other gambling losses; the money you lose betting on sports can be deductible if you choose to itemize. Just as with any other deductions you claim, keeping detailed records is essential.

With any money that is deemed income by the IRS, it’s important to know what your specific tax bracket is to avoid underpayment. The highest federal tax rate is currently 35%, and that’s in addition to the 3.23% you would owe the state on your sports betting winnings.
As most operators only withhold 25% of winnings automatically, you may owe additional federal tax above and beyond what the operator withheld based on your personal income. That amount would be due upon filing.
That applies equally to those who play casino games in person and online in the Hoosier State.
Taxes on online casino games and online poker
While online poker and online casinos have yet to be legalized, when they do, taxes will work the same as they do at land-based casinos.
The operators of the games should send you a W-2G summing up all your winnings from the year once they reach certain thresholds depending on the type of game. Those are:
- Your winnings (not reduced by the wager) of at least $1,200 from a bingo game or slot machine
- The winnings (reduced by the wager) of at least $1,500 from a keno game
- Your winnings (reduced by the wager or buy-in) of at least $5,000 from a poker tournament
- The winnings (except winnings from bingo, slot machines, keno, and poker tournaments) reduced, at the option of the payer, by the wager are $600 or more, and at least 300 times the amount of the bet
- Your winnings are subject to federal income tax withholding (either regular gambling withholding or backup withholding)
With the W-2G in hand, you have what you need to report your winnings and pay any applicable taxes to both the state of Indiana and the IRS. Let’s review all the pertinent information that is relevant regardless of where your winnings came from:
- The gaming operator you placed your wagers with should send you a W-2G
- You can use the W-2G to report your winnings on both your federal and state taxes
- How much federal tax you pay depends on your personal income
- The Indiana rate is 3.23%
- If you don’t get a W-2G, you still have to claim your winnings as income if they qualify
- You can deduct your losses on your federal return, but you must itemize
- If you do go that route, keep any and all records from the transactions
With those simple things in mind, you too can stay safe from tax fraud while gaming in Indiana. Enjoy the games!
