The 2026 loss rule
For 2026, the federal wagering-loss limit is the smaller of 90% of eligible losses or gambling winnings. A recreational gambler generally claims the loss deduction by itemizing. The IRS Publication 505 and current statute linked below support this rule. Sources checked November 3, 2026.
If you already itemize without gambling losses, this model deducts the allowed loss amount from winnings. If you keep the standard deduction, it applies no separate gambling-loss deduction. The modeled income increase is then multiplied by your entered marginal federal rate.
Choose Unsure or switching if gambling losses might change your deduction method. The calculator can show the statutory loss limit, but it withholds a single-rate tax estimate because that situation requires comparing complete returns.
Worked example
Suppose reportable winnings are $10,000, eligible losses are $10,000, and you already itemize without those losses. The modeled loss deduction is min($10,000 × 90%, $10,000) = $9,000. The modeled increase in taxable income is $1,000.
At an assumed 22% marginal rate, the estimated federal tax component is $220. This assumes the whole income increment and deduction affect the same bracket and that other tax calculations stay unchanged.
Keeping the standard deduction under the same inputs produces a $10,000 modeled income increase and a $2,200 federal component at 22%. These figures compare the selected assumptions; they do not decide which deduction method you should use.
Use the right figures
Enter reportable gambling income from your records. A casino withdrawal or a displayed account balance is not automatically the taxable winnings amount. Keep winnings and eligible documented losses separate; this tool does not determine your permitted accounting method.
The fixed-rate model excludes state and local tax, professional gambling, nonresident rules, tax credits, and other effects of adjusted gross income. It also does not calculate bracket changes or the 2026 high-income limitation on itemized deductions.
Withholding and reporting
Federal withholding is a payment toward tax. The 24% rate in certain IRS gambling-withholding rules is not a universal final tax rate on casino winnings. Enter actual withholding to compare it with this estimated component.
If withholding exceeds the estimate, the difference describes that comparison. A refund or final amount due depends on your complete return and other payments.
Form W-2G reporting thresholds are separate from your obligation to report taxable gambling income. Keep supporting records even if no W-2G is issued.
Common questions
Why can tax remain after a break-even year?
The 2026 rule can limit the deduction to 90% of eligible losses even when winnings and losses are equal. The $10,000 example above illustrates that difference.
Does this calculate my full tax bill?
It calculates one federal component under the selected assumptions. A complete return is needed to determine total liability, payments, and any balance due or refund.
