The Ohio sports betting tax works in two layers: Ohio charges a flat 2.75% state income tax on your winnings starting in 2026, and the IRS taxes those same winnings as ordinary income at your federal marginal rate. Sportsbooks withhold 24% from certain large payouts for the IRS, but you owe tax on every winning bet whether or not anything was withheld and whether or not you ever get a tax form in the mail.
Ohio’s Flat 2.75% State Rate
Beginning in 2026, Ohio taxes all personal income above $26,050 at a single flat rate of 2.75%.1Ohio Legislative Service Commission. Ohio Revised Code 5747.02 – Tax Rates The calculation is $332 plus 2.75% of every dollar above that threshold. If your total taxable income (counting your sports betting winnings) comes in below $26,050, you owe no Ohio income tax.
Because there is only one bracket now, a winning year at the sportsbook cannot push you into a higher state rate. Ohio previously used a graduated structure that topped out at 3.5% in 2025.
One number that trips people up: Ohio charges sportsbook operators a 20% tax on their gross gaming receipts.2Ohio Department of Taxation. Sports Gaming Receipts Tax SGRT 2023-01 Tax Rate That bill belongs to the operator, not you. Your rate as a bettor is 2.75%.
Federal Tax and the 24% Withholding Rule
The IRS treats gambling winnings as ordinary income, no different from wages.3Internal Revenue Service. Topic No. 419, Gambling Income and Losses Your federal rate is whatever marginal bracket your total income falls into, somewhere between 10% and 37%.
For large payouts, the sportsbook withholds 24% for the IRS before paying you. That mandatory withholding kicks in when your net winnings exceed $5,000 and the payout is at least 300 times the amount you wagered.4Office of the Law Revision Counsel. 26 USC 3402 – Income Tax Collected at Source A $10 bet that returns a profit of more than $5,000 would qualify.
The 24% is a prepayment, not a final tax. If your actual federal rate on the income is lower, the difference comes back as a refund. If it is higher, you owe the balance when you file.
When You Get a W-2G
Sportsbooks report certain payouts to the IRS on Form W-2G.5Internal Revenue Service. About Form W-2G, Certain Gambling Winnings For 2026, the reporting floor for sports bets rose to $2,000, up from the longstanding $600, because Congress tied it to inflation.6Internal Revenue Service. Instructions for Forms W-2G and 5754 A W-2G is issued when your net winnings reach $2,000 and the payout is at least 300 times your wager.
The form carries your name, address, Social Security number, gross winnings, and the transaction date. You get a copy, the IRS gets a copy, and Ohio’s Department of Taxation gets one. Expect the sportsbook to ask for your ID before paying out a qualifying win.
Winnings Below the Threshold Are Still Taxable
This is where casual bettors get burned. The $2,000 W-2G floor is a paperwork trigger for the sportsbook. It is not a tax-free zone for you. The IRS requires you to report all gambling winnings on your return, including amounts that never generate a W-2G.3Internal Revenue Service. Topic No. 419, Gambling Income and Losses
Ohio takes the same position. The Department of Taxation requires you to report all sports gaming winnings from bets placed in Ohio, regardless of whether the operator was required to report them federally or withhold anything.7Ohio Department of Taxation. Income – General Information That duty applies to Ohio residents and to visitors who placed bets in the state.
Your sportsbook app keeps a running transaction history. Download it at year end. If you bet on more than one platform, pull records from each. The IRS also recommends keeping a diary of wins and losses backed by tickets, receipts, or account statements.
Deducting Your Gambling Losses
You can offset winnings with gambling losses on both your federal and Ohio returns, but only if you itemize deductions on your federal return instead of taking the standard deduction. The deduction is capped at the amount of gambling income you reported. Won $8,000 and lost $12,000? You can deduct $8,000, not $12,000.3Internal Revenue Service. Topic No. 419, Gambling Income and Losses Losses cannot create a net deduction against other income.
Ohio did not always allow this. Before House Bill 33 amended Ohio Revised Code Section 5747.01, Ohio taxpayers who itemized federally still could not deduct gambling losses on their state return, meaning the state effectively taxed gross winnings. The alignment with federal treatment matters most if you bet regularly and your wins and losses roughly cancel out.
Itemizing only pays off if your total itemized deductions beat the standard deduction ($15,000 single, $30,000 married filing jointly in 2026). For many recreational bettors, the standard deduction still wins and the loss deduction is unavailable. Either way, keep the records: account statements, bet slips, deposits, and withdrawals. Without documentation, a deducted loss will not survive scrutiny.
Quarterly Estimated Payments
If a winning year leaves you with more tax owed than withholding covers, the IRS expects quarterly estimated payments rather than one lump at filing time. The federal rule applies when you expect to owe $1,000 or more after withholding and credits.8Internal Revenue Service. 2026 Estimated Tax for Nonresident Alien Individuals Ohio follows the same quarterly schedule.9Ohio Department of Taxation. Estimated Payments
The 2026 deadlines are:
- First quarter (January through March): April 15
- Second quarter (April through May): June 15
- Third quarter (June through August): September 15
- Fourth quarter (September through December): January 15, 2027
If a due date falls on a weekend or holiday, it slides to the next business day.10Internal Revenue Service. Estimated Tax Miss a payment and underpayment penalties plus interest start accruing. If you hit a big parlay in July with no withholding taken out, the September payment keeps the penalty from compounding.
Don’t Forget School District Income Tax
Ohio has roughly 200 school districts that levy their own income tax, and whether your winnings get taxed depends on which base your district uses. “Traditional” districts calculate the tax from Ohio taxable income, which includes gambling winnings. “Earned income” districts tax only wages, salaries, and business income, so gambling winnings sit outside their reach.
If your district has a school district income tax, you file an SD 100 alongside your Ohio IT 1040. Check the Department of Taxation’s lookup tool to see which base your district uses. School district tax is one of the easiest line items for Ohio bettors to overlook and one of the most common sources of a surprise bill.
How to File
On your federal return, gambling winnings go on Schedule 1 (Form 1040), Line 8b, labeled “Gambling income.” That total flows to your Form 1040. Loss deductions, if you itemize, go on Schedule A as “Other Itemized Deductions.”3Internal Revenue Service. Topic No. 419, Gambling Income and Losses
For Ohio, the same winnings go on your IT 1040.11Ohio Department of Taxation. Tax 101 The state already has copies of any W-2G forms you received and will cross-reference your return. A mismatch triggers a notice. If you owe school district tax, file the SD 100 at the same time.
The most common filing mistake is ignoring winning bets that never generated a W-2G. With the reporting threshold now at $2,000, more winning bets will stay off the automatic paperwork than before.6Internal Revenue Service. Instructions for Forms W-2G and 5754 Your sportsbook still has every transaction on file, and the IRS can request it. Reporting everything and keeping records is the only approach that holds up on review.
A Note on Professional Gambler Status
Everything above assumes you bet recreationally. If gambling is your primary income source, pursued full-time and for a livelihood, the IRS lets you file as a professional, reporting on Schedule C and deducting business expenses alongside losses. The tradeoff is self-employment tax at 15.3% on your net earnings, which recreational bettors do not pay on winnings. Most sports bettors do not qualify, and the IRS scrutinizes claims that try.
