The Louisiana state tax on gambling winnings is a flat 3%, applied to every dollar you win with no deduction allowed for gambling losses. Both residents and nonresidents who win money in Louisiana owe it, and casinos withhold it automatically on certain payouts. Even if you lost more than you won over the year, Louisiana still taxes the full amount of your winnings.
What Counts as a Gambling Win
Louisiana casts a wide net. Any money or prize you receive from gambling is taxable state income: lottery tickets (including Powerball and Mega Millions), scratch-offs, casino table games, slot machines, video poker, keno, retail and online sports betting, fantasy sports contests, horse racing, off-track betting, raffles, and sweepstakes.
Non-cash prizes count too. If you win a car, a vacation package, or any physical prize, the fair market value is taxable income.1Internal Revenue Service. Topic No. 419, Gambling Income and Losses A casino might hand you the keys to a new truck, but Louisiana sees the retail value of that truck as income you owe 3% on. The same goes for high-value comps like trips or event packages awarded through promotions or player reward programs.
When the Casino Withholds Louisiana Tax
Louisiana requires payers to withhold state tax at 3% in two situations. First, whenever the payer is already required to withhold federal income tax on the same winnings. Federal withholding applies at 24% when winnings minus the wager exceed $5,000 from sources like lotteries, sweepstakes, sports bets, and pari-mutuel wagering with a payout of at least 300 times the wager.2Internal Revenue Service. Instructions for Forms W-2G and 5754
Second, Louisiana has its own rule for slot machines: casinos must withhold the 3% state tax on any slot payout exceeding $1,200, whether or not federal withholding is triggered.3Louisiana Administrative Code. Louisiana Administrative Code 61.III.1525 – Income Tax Withholding on Gaming Winnings Note one wrinkle for 2026: the federal reporting threshold for slot winnings on Form W-2G rose to $2,000 starting in calendar year 2026.4Internal Revenue Service. Instructions for Forms W-2G and 5754 (Rev. January 2026) Louisiana’s regulation still specifies $1,200 for state withholding on slots, so a payout between $1,200 and $2,000 may have Louisiana tax withheld even though no federal W-2G is issued.
Withholding is only a prepayment. When you file your Louisiana return, you reconcile what was withheld against what you actually owe. Too much withheld means a refund; too little means you pay the difference.
Why Your Losses Do Not Reduce the Louisiana Bill
This is the part that surprises people. On your federal return, if you itemize, you can deduct gambling losses up to the amount of your winnings. Louisiana does not follow that approach. The state return starts with your federal adjusted gross income (which includes gambling winnings) and then subtracts Louisiana’s standard deduction and a limited deduction for qualifying medical expenses only.5Louisiana Department of Revenue. What’s New for Louisiana 2025 Individual Income Tax Gambling losses on your federal Schedule A never flow through to Louisiana.
Say you won $10,000 at Louisiana casinos over the year and lost $8,000. On your federal return you can offset the $10,000 with $8,000 in losses, leaving $2,000 in net gambling income. Louisiana ignores that offset. The full $10,000 stays in your income for state purposes, and 3% applies, even though you only came out $2,000 ahead. Keeping loss records still matters for your federal return, but do not expect those losses to touch your Louisiana tax.
Filing Your Louisiana Return
Forms and Deadline
Louisiana residents file Form IT-540 to report all income, including gambling winnings.6Louisiana Department of Revenue. 2025 Louisiana Resident Individual Income Tax Return (IT-540) Nonresidents who won money gambling in Louisiana use Form IT-540B.7Louisiana Department of Revenue. Instructions for Preparing Your 2024 Louisiana Resident Income Tax Return Form (IT-540) Your winnings are already inside the federal adjusted gross income that carries over. Any Louisiana tax withheld on your W-2G is credited as a payment toward your final state liability.
Louisiana’s filing deadline is May 15, not April 15. That mismatch with the federal deadline catches many filers off guard.8Louisiana Department of Revenue. What Is the Due Date of the Individual Income Tax Return? The Louisiana Department of Revenue encourages electronic filing through its LA File IT system or authorized tax software.
Automatic Extension
Louisiana grants an automatic six-month extension to file, pushing the deadline to November 15 for calendar-year filers.9Louisiana Department of Revenue. Louisiana State Income Tax Deadline Is May 15 No separate request is needed. The extension covers paperwork only. Any tax you owe is still due by May 15, and penalties and interest start accruing after that date if you have not paid.
Nonresidents
If you live in another state and won at a Louisiana casino, racetrack, or through Louisiana-based sports betting, you must file a Louisiana nonresident return to report that income.10Louisiana Department of Revenue. I Am a Resident of Texas and Won Money at a Louisiana Casino and They Withheld Louisiana Taxes. Do I Get Back All That Was Withheld? If the casino withheld more than Form IT-540B says you actually owe, the department refunds the difference. Nonresidents from states with their own income tax may be able to claim a credit at home for tax paid to Louisiana, though the rules vary state to state.
Estimated Payments for Large Wins
If you expect to owe more than $1,000 in Louisiana income tax after subtracting withholding and credits ($2,000 for married couples filing jointly), quarterly estimated payments are required.11Louisiana Department of Revenue. Declaration of Estimated Income Taxes That matters most for frequent gamblers and for anyone who hits a large jackpot early in the year without enough withheld to cover the eventual bill.
Quarterly payments are due April 15, June 15, September 15, and January 15 of the following year.11Louisiana Department of Revenue. Declaration of Estimated Income Taxes You can pay the full amount with the first installment or spread it across all four. Filing your return and paying the balance in full by January 31 lets you skip the January 15 installment without penalty.
Penalties and Interest for Missing the Deadline
Missing May 15 without filing costs 5% of the tax due for every 30-day period you are late, capped at 25%.12Louisiana Legislature. Louisiana Revised Statutes Title 47 Section 1602 – Penalty for Failure to Make Timely Return Failing to pay by May 15 triggers a separate penalty of 0.5% of the unpaid tax per 30-day period, also capped at 25%.13Louisiana Department of Revenue. Why Are Delinquent Penalties Assessed? Both can run at the same time if you neither file nor pay.
Interest also accrues on the unpaid balance. For 2026, the annual interest rate on delinquent Louisiana tax is 10.5%.14Louisiana Department of Revenue. R-1111 Interest Rate Schedule Interest runs from the original due date, not from when you eventually file. On a $3,000 tax bill, six months past the deadline adds roughly $150 in interest alone before any penalty. The extension buys time to file, not time to pay.
Keeping Records of Wins and Losses
You will receive a Form W-2G for any payout that meets or exceeds the federal reporting threshold, which is $2,000 for 2026 in most gambling categories.4Internal Revenue Service. Instructions for Forms W-2G and 5754 (Rev. January 2026) The form shows the gross amount won and any federal or state tax withheld. All gambling winnings must be reported even if no W-2G was issued.1Internal Revenue Service. Topic No. 419, Gambling Income and Losses
Keep your own log throughout the year. For each session, record the date, the type of game, the name and location of the casino or site, and the amounts won and lost. Save player’s club statements, wagering tickets, and receipts from online accounts. Bank and credit card statements showing deposits to gambling platforms help too. The IRS generally requires records for three years from the date you file, or six years if you underreport income by more than 25%.15Internal Revenue Service. How Long Should I Keep Records Because gambling income can prompt audit scrutiny, six years is the safer benchmark.
