Sports Gambling Taxes: Withholding, Deductions, and Reporting

Sports gambling taxes work like this: every dollar you win betting on sports is ordinary income to the IRS, taxed at the same 10% to 37% federal rates that apply to your paycheck.¹ You report winnings on Schedule 1 of Form 1040 whether or not the sportsbook sends you a tax form, and for 2026 two rules have changed that matter to most bettors: the reporting threshold jumped from $600 to $2,000, and you can now deduct only 90% of your gambling losses.

How Your Winnings Get Taxed

Your winnings stack on top of your other income. A $5,000 parlay payout doesn’t get taxed at a single flat rate; it sits on top of your salary, and only the portion that lands in a higher bracket gets taxed at that higher rate. For 2026, a single filer pays 10% on the first $12,400 of taxable income and climbs through six brackets to 37% above $640,600.²

The platform doesn’t matter. Licensed app, casino sportsbook, offshore site, office pool — the IRS treats winnings the same. You owe the tax even if no form arrives in the mail and even if the amount is small.¹

When Sportsbooks Report and Withhold

Reporting and withholding are two different things, triggered by two different thresholds. Confusing them is a common mistake.

The W-2G Reporting Threshold

For payments made on or after January 1, 2026, sportsbooks must issue a Form W-2G once your winnings hit $2,000, up from the old $600 threshold.³ The form shows your gross winnings and any tax withheld, and a copy goes to the IRS. Below $2,000 you still owe tax and still have to report the income yourself.¹

The 24% Withholding Trigger

A sportsbook takes 24% off the top only when both of these are true: your winnings minus the original wager exceed $5,000, and the payout is at least 300 times the amount you bet.⁴ A $20 parlay that hits for $8,000 triggers withholding, because the $7,980 net exceeds $5,000 and the payout is 400 times the bet. A $1,000 straight bet that returns $6,500 does not, because the payout is only 6.5 times the wager.

Separate 24% “backup withholding” kicks in if you don’t provide a valid Social Security number when collecting.⁴ Either way, the withheld amount shows up as a credit on your return, like paycheck withholding.

Deducting Your Losses

You can write off gambling losses, but three restrictions apply and the third one is new for 2026.

First, you have to itemize on Schedule A. The 2026 standard deduction is $16,100 for single filers and $32,200 for married joint filers. Unless your itemized total (mortgage interest, state taxes, charitable gifts, plus your gambling losses) beats those numbers, itemizing costs you money. Most casual bettors take the standard deduction and get no benefit from this write-off.¹

Second, your deduction can’t exceed your reported winnings. Win $3,000 and lose $7,000, and you deduct $3,000. The other $4,000 disappears — no carryforward to next year, no offset against your salary.

Third, and this is the 2026 change: only 90% of your losses are deductible.⁵ Win $10,000 and lose $10,000 and you’d expect to break even for tax purposes. You don’t. You can deduct $9,000, leaving $1,000 in taxable gambling income. Frequent bettors feel this hardest, because it guarantees a tax bill any time wins and losses coexist in the same year.

The Hidden Cost: Winnings Inflate Your AGI

Here’s what catches people off guard. Winnings sit on the income side of your return; losses come off as a deduction. That means your adjusted gross income goes up by the full amount of your winnings even when your losses cancel them out on paper. AGI is the number the tax code uses to gate dozens of benefits.

A higher AGI can:

Push you into Medicare Part B and D premium surcharges under IRMAA.
Make more of your Social Security benefits taxable.
Phase out the Child Tax Credit, education credits, and clean vehicle credits.
Cut off your ability to contribute to a Roth IRA.
Raise the 7.5%-of-AGI floor for deducting medical expenses.

A bettor who wins $40,000 and loses $40,000 feels like they broke even. On the tax return, their AGI is $40,000 higher, and that can quietly cost thousands in surcharges and lost credits.

State Taxes Often Hit Harder

States that don’t tax income — including Texas, Florida, Nevada, and Washington — don’t tax your winnings either. Everywhere else, gambling income is treated as ordinary income at state rates that can top 10%.

The trap is losses. Many states don’t let you deduct gambling losses at all. You may write off $8,000 federally and still owe state tax on the full $8,000 in winnings. Check your state department of revenue’s rules before assuming the federal math carries over.

How to Report It on Your Return

Winnings go on Schedule 1 (Form 1040), line 8b, under “Other Income,” and flow into your total income on Form 1040. If you got a W-2G, use the gross winnings from Box 1 and put any federal tax withheld from Box 4 on line 25c of Form 1040 as a credit.⁶

If you itemize and are deducting losses, those go on Schedule A as “Other Itemized Deductions.” Enter no more than 90% of your actual losses, and never more than your total reported winnings.⁵

When friends share a winning ticket, the person collecting fills out Form 5754 to identify each member’s share, and the sportsbook then issues separate W-2Gs.⁷ Skip that step and the whole tax bill lands on whoever collected the money.

Estimated Payments

Big win with no withholding? You may need quarterly estimated payments to avoid an underpayment penalty at filing time.¹ The general rule: if you expect to owe $1,000 or more beyond what’s already been withheld, estimated payments are the safer route. IRS Publication 505 walks through the calculation.

Records the IRS Expects

The IRS wants a detailed log, not a shoebox. Track the date, type of bet, name and location of the sportsbook or app, and the amounts won and lost on each transaction.¹

Keep supporting proof: betting slips, app statements, bank and card records for deposits and withdrawals, and every W-2G. Year-end summaries from mobile apps are useful, but the IRS wants transaction-level detail. If you claim losses and can’t prove them, the deduction gets thrown out and you owe tax on your full reported winnings.

Penalties for Not Reporting

The IRS already has a copy of every W-2G. When your return doesn’t match, or doesn’t exist, the mismatch is flagged automatically.

Failure to file: 5% of unpaid tax per month, capped at 25%.⁸
Failure to pay: 0.5% of unpaid tax per month, also capped at 25%.
Accuracy-related penalty: 20% of the underpayment if you understate your tax by the greater of 10% or $5,000.⁹

Interest runs on all of it from the original due date. Deliberate concealment can escalate to fraud charges, which carry steeper penalties.

Two Situations With Their Own Rules

If you bet at a scale and regularity that make sports betting your actual trade or business, the IRS may treat you as a professional gambler. Professionals report on Schedule C, can deduct business expenses like data subscriptions and travel, but pay an added 15.3% self-employment tax on net earnings and are still subject to the 90% loss cap.⁶⁵ The IRS often contests the claim, so this is not a status to assume casually.

If you bet through an offshore sportsbook and your foreign account balances total more than $10,000 at any point in the year, you also have to file FinCEN Form 114 (the FBAR), and possibly Form 8938 on top of it at higher balance thresholds.¹⁰ Penalties for missing an FBAR start at $10,000 per account per year and get much larger if the failure is willful. The tax you owe on the winnings themselves is the same either way; the reporting is the extra piece.
