Indiana gambling tax works in two layers for the person who won the money: a flat 2.95% state income tax for the 2026 tax year, plus a county income tax between 1.20% and 2.95% depending on where you live.1Indiana Department of Revenue. Departmental Notice 1 – How to Compute Withholding for State and County Income Tax Federal income tax applies on top of that. Every dollar counts as taxable income, whether it came from a casino floor, a sportsbook app, the Hoosier Lottery, or a scratch-off. A W-2G at the cage does not change what you owe. It only changes whether some of the tax was collected before you left.
When Indiana Withholds Tax at the Cage
Gambling establishments in Indiana are required to withhold state income tax at 2.95% when your winnings cross specific thresholds. For 2026, withholding applies to slot machine winnings of $2,000 or more (before subtracting the wager) and keno winnings of $2,000 or more (after subtracting the wager).2Indiana Department of Revenue. Departmental Notice 16 – Requirements on Withholding Individual Income Tax on Winnings Those numbers used to be $1,200 for slots and $1,500 for keno, so withholding now triggers less often than it once did.
Lottery prizes above $1,200 also trigger withholding.3Indiana General Assembly. Indiana Code 6-3-4-8.2 – Income Withholding, Gambling Winnings And any time federal law requires federal withholding on a payout, Indiana requires state withholding on the same payout.
When withholding happens, the payer issues IRS Form W-2G showing your winnings, the federal tax withheld, and the state tax withheld. You get a copy. The state gets a copy.4Internal Revenue Service. Form W-2G – Certain Gambling Winnings Winning below a threshold does not make the money tax-free. It just means you were paid in full and now owe the tax yourself when you file.
The Federal Layer
The IRS taxes gambling winnings as ordinary income and requires you to report all of it on Schedule 1 of Form 1040, whether or not a W-2G was issued.5Internal Revenue Service. Schedule 1 (Form 1040) – Additional Income and Adjustments to Income Federal withholding is 24% and generally kicks in when winnings minus the wager exceed $5,000, though the exact trigger varies by game type.
Add it up on a large win and the cage may hold back 24% federal, 2.95% Indiana state, and your county rate before you see any cash. If your actual tax rate ends up lower than what was withheld, you get the difference back as a refund. If withholding falls short, you owe the balance.
County Tax Stacks on Top
Each of Indiana’s 92 counties imposes its own income tax, and gambling winnings are included right along with wages. For 2026, county rates run from 1.20% to 2.95%.1Indiana Department of Revenue. Departmental Notice 1 – How to Compute Withholding for State and County Income Tax Combined with the 2.95% state rate, your total Indiana tax before federal runs roughly 4.15% to 5.90%. When a casino or sportsbook withholds, it uses your county of residence, so W-2G totals already include the county piece.
Reporting Every Win
All gambling winnings go on your Indiana IT-40. Indiana bases adjusted gross income on the federal definition under Section 62 of the Internal Revenue Code, which sweeps in gambling income.6Indiana General Assembly. Indiana Code 6-3-1-3.5 – Adjusted Gross Income The federal side works the same way through Schedule 1.5Internal Revenue Service. Schedule 1 (Form 1040) – Additional Income and Adjustments to Income
The IRS wants a session-by-session record: date, type of game, name and location of the establishment, amounts won and lost, and who was with you. That level of detail feels absurd for a Friday at the slots, but the IRS has used Revenue Procedure 77-29 to reject returns from taxpayers who couldn’t produce it. Keep tickets, receipts, and W-2Gs together with a running log. That combination is your best defense if either the IRS or the Indiana Department of Revenue asks questions.
Deducting Gambling Losses
You can deduct gambling losses, but only up to the amount you reported in winnings for the same year. A net loss cannot reduce your other taxable income.7Internal Revenue Service. Topic No. 419, Gambling Income and Losses
Here is the part that catches most casual gamblers. Losses are only deductible as an itemized deduction on Schedule A. If you take the standard deduction, you get no benefit from your losses even though you still owe tax on every dollar of winnings.7Internal Revenue Service. Topic No. 419, Gambling Income and Losses Win $8,000 and lose $10,000 across the year, take the standard deduction, and you still owe tax on the full $8,000.
Indiana follows federal treatment. You can offset winnings with losses on your Indiana return only if you itemized on Schedule A federally. Without itemizing, there is no separate state mechanism to net them out.
When You Need to Make Estimated Payments
A big win partway through the year can leave you underwithheld. Indiana requires estimated tax payments if you expect to owe $1,000 or more in combined state and county tax beyond what withholding covers.8Indiana Department of Revenue. Estimated Payments
Payments are due April 15, June 15, September 15, and January 15 of the following year. Miss a quarter or underpay one, and the Department of Revenue assesses a 10% penalty on that installment’s shortfall.8Indiana Department of Revenue. Estimated Payments You can sidestep the penalty by paying at least 90% of your current-year tax, or 100% of last year’s tax (110% if your federal adjusted gross income exceeds $150,000, or $75,000 if married filing separately).
If your winnings are lumpy rather than spread evenly, Indiana’s annualized income installment method on Schedule IT-2210A lets you match payments to the quarters when the money actually came in. That is often a better fit than four equal payments when a single tournament or jackpot drives most of your gambling income.
If You Live Out of State
Winnings from an Indiana casino or an Indiana-licensed sportsbook are Indiana-source income even if you live elsewhere. Indiana taxes income derived from sources within the state regardless of residency.3Indiana General Assembly. Indiana Code 6-3-4-8.2 – Income Withholding, Gambling Winnings Casinos withhold from nonresidents at the same thresholds as residents. You file Form IT-40PNR to report the income. Your home state will usually give you a credit for the tax you paid Indiana so the same dollars are not taxed twice.
Penalties for Not Reporting or Paying
Late or short payments carry a 10% penalty on the unpaid tax, with a $5 minimum.9Indiana Department of Revenue. Fines, Fees and Penalties Failing to file at all triggers a separate penalty of $10 per day, capped at $250.10Indiana General Assembly. Indiana Code 6-8.1-10-2.1 – Liability for Penalty, Reasonable Cause Presumption
Interest runs on top. For calendar year 2026, Indiana charges 7% annual interest on underpaid tax, calculated from the original due date until the balance is paid.11Indiana Department of Revenue. Departmental Notice 3 – Interest Rates for Calendar Year 2026 The Department of Revenue generally cannot waive interest, only penalties.
Deliberate evasion is a separate matter. IC 6-8.1-10-4 imposes criminal penalties on people who knowingly fail to file or pay. Classification depends on the amount and circumstances, and a conviction can carry jail time and additional fines on top of civil penalties.
