Calculate Your Taxable Gambling Income Under the 90% Cap
Enter winnings, losses and your tax rate to calculate 2026 phantom income, deductible losses and estimated extra federal tax under the new 90% cap.
A break-even recreational gambler who itemizes and has $100,000 of supported winnings and $100,000 of supported losses has $10,000 of taxable gambling income under the stated 2026 federal formula. At a 24% marginal rate, that produces an estimated $2,400 of extra federal tax compared with the 2025 loss-deduction formula. The tax estimate is not final liability.
The 2026 deduction is the lesser of winnings or 90% of supported losses. Every break-even itemizer therefore retains taxable gambling income equal to 10% of winnings. A net-losing year can also produce taxable income until losses reach approximately 111.11% of winnings, where 90% of losses equals the winnings cap.
Enter supported winnings, supported losses and a marginal rate; then move the loss-ratio slider to find where taxable income disappears.
For a recreational gambler who itemizes. Values shown compare the stated 2026 90% loss limit with the stated 2025 losses-up-to-winnings formula.
Use supported tax figures, not handle, deposits, withdrawals or transfers. Changing the slider recalculates losses from the entered winnings.
Estimated extra federal tax versus 2025: $2,400.00
Break-even result: 10% of winnings remains as taxable gambling income under the stated 2026 formula.
With $100,000.00 of winnings, taxable gambling income reaches zero at approximately $111,111.11 of losses.
| Scenario | Winnings | Losses | Economic Result | 2026 Deduction | Taxable Income | Phantom Gap |

How the 2026 Calculation Works
For a recreational gambler who itemizes, let:
- W = supported gambling winnings
- L = supported gambling losses
- R = selected marginal federal rate as a decimal
The stated 2026 calculation is:
90%-of-losses amount = L × 0.90
Allowed deduction = min(W, L × 0.90)
Taxable gambling income = W − allowed deduction
Economic profit or loss is calculated separately:
Economic result = W − L
Positive economic profit = max(W − L, 0)
Phantom-income gap =
max(taxable gambling income − positive economic profit, 0)
The zero floor keeps genuine gambling profit from being mislabeled as phantom income. If winnings are $15,000 and losses are $10,000, the gambler made $5,000 economically. The 2026 deduction is $9,000, leaving $6,000 of taxable gambling income. Of that amount, $5,000 is real profit and $1,000 is the phantom-income gap.
The optional tax illustration is:
Estimated extra federal tax = phantom-income gap × R
This applies one selected marginal rate to the additional income. It does not calculate progressive brackets, credits, alternative minimum tax, state tax or other return-level interactions.
Tax-advisory sources describe the 2026 deduction as the lesser of winnings or 90% of supported losses. They describe the 2025 comparison as allowing supported losses up to winnings. The Forbes analysis of the enacted change also explains the separate reporting of recreational gambling winnings and losses.
Break-Even Gambling Produces 10% Phantom Income
For equal winnings and losses, the arithmetic is direct:
Winnings: $50,000
Losses: $50,000
Economic result: $0
90% of losses: $45,000
Allowed deduction: $45,000
Taxable gambling income: $5,000
Phantom-income gap: $5,000
The gambler broke even but has $5,000 remaining after the simplified gambling-income calculation. That is taxable income in the worksheet, not $5,000 of tax.
A CPA advisory article identifies Public Law 119-21, Section 70114 as the provision amending Internal Revenue Code Section 165(d) for tax years beginning after December 31, 2025. It also provides the same $50,000 break-even result and describes 2025 as retaining the prior losses-up-to-winnings treatment. Review the CPA explanation of the 2026 formula.
At break-even, phantom income scales directly with winnings:
| Winnings | Losses | Economic Result | 2026 Deduction | Phantom Income |
|---|---|---|---|---|
| $15,000 | $15,000 | $0 | $13,500 | $1,500 |
| $50,000 | $50,000 | $0 | $45,000 | $5,000 |
| $100,000 | $100,000 | $0 | $90,000 | $10,000 |
These are arithmetic applications of the 90% formula, not complete-return calculations.
Taxable Income Disappears At A 111.11% Loss Ratio
The percentage limit controls while 90% of losses is less than winnings:
0.90 × losses < winnings
Solving for losses gives:
losses < winnings ÷ 0.90
That boundary is approximately 111.11% of winnings. With $100,000 of winnings, taxable gambling income remains positive while supported losses are below approximately $111,111.11. At that point, 90% of losses reaches the $100,000 winnings cap.
This produces an unusual range for net losers:
| Winnings | Losses | Loss Ratio | Economic Result | 2026 Taxable Income |
|---|---|---|---|---|
| $100,000 | $100,000 | 100% | $0 | $10,000 |
| $100,000 | $110,000 | 110% | −$10,000 | $1,000 |
| $100,000 | $200,000 | 200% | −$100,000 | $0 |
The gambler with $110,000 of losses lost $10,000 economically but still has $1,000 of taxable gambling income. The gambler with $200,000 of losses receives a deduction capped at $100,000, leaving no taxable gambling income in this simplified calculation.
Excess losses do not become a general deduction against wages or other nongambling income. The reviewed guidance also says unused gambling losses generally do not carry forward.
The 2025 Comparison Measures The New-Law Difference
The stated 2025 calculation is:
Allowed deduction = min(W, L)
Taxable gambling income = W − allowed deduction
For a recreational itemizer, the difference between the 2025 and 2026 taxable amounts is the phantom-income gap used by the calculator.
| Scenario | Economic Result | 2025 Deduction | 2026 Deduction | 2026 Taxable Income | Phantom Gap |
|---|---|---|---|---|---|
| $100,000 wins / $100,000 losses | $0 | $100,000 | $90,000 | $10,000 | $10,000 |
| $15,000 wins / $10,000 losses | $5,000 | $10,000 | $9,000 | $6,000 | $1,000 |
| $100,000 wins / $110,000 losses | −$10,000 | $100,000 | $99,000 | $1,000 | $1,000 |
| $100,000 wins / $200,000 losses | −$100,000 | $100,000 | $100,000 | $0 | $0 |
FreeTaxUSA’s tax-professional guidance describes the 2025 and 2026 formulas and provides examples for recreational and potential professional paths. See its explanation of the gambling-loss change.
The Calculator Requires Supported Tax Figures
Enter supported annual winnings and losses determined under the reporting and accounting method applicable to you. Do not enter betting handle, total wagers placed, deposits, withdrawals, account transfers or an unreconciled transaction export.
The calculator does not convert individual wagers or sportsbook activity into tax-ready annual figures. If records do not clearly distinguish transactions, sessions and supported totals, reconcile them before using the formula.
Use nonnegative dollar amounts. Enter a marginal rate as a percentage, such as 24%, rather than $24. With $10,000 of winnings and no losses, the allowed deduction is zero, taxable gambling income is $10,000 and the phantom-income gap is zero because the entire amount is economic profit.
Avoid counting the same activity through multiple records. A platform statement, Form W-2G, personal log and bank record may all refer to one win.
A reliable reconciliation should identify every account and venue, determine the period covered by each statement, match Forms W-2G to underlying activity where possible, flag overlapping records and separate tax inputs from deposits, withdrawals, transfers and handle.
Useful supporting records include:
- Contemporaneous win-loss or session logs
- Dates and locations of play
- Games, contests or wager types
- Tickets, betting slips and receipts
- Casino and sportsbook statements
- Forms W-2G
- Related bank, card, wallet or payment records
- Written explanations of adjustments and discrepancies
A Form W-2G threshold is an information-reporting rule for the payer, not a tax-free threshold for the recipient. Taxable gambling winnings may remain reportable when no Form W-2G is issued. This page does not reproduce activity-specific thresholds because final instructions should be checked for the applicable tax year.
Standard-Deduction Users Need A Different Comparison
The calculator models a recreational gambler claiming an itemized gambling-loss deduction. The cited guidance says a recreational taxpayer taking the standard deduction generally receives no separate gambling-loss deduction.
For that simplified path:
Allowed gambling-loss itemized deduction = $0
Taxable gambling income before other return effects =
supported winnings
A recreational standard-deduction user with $50,000 of winnings and $50,000 of supported losses could therefore have the full $50,000 remaining in income before other return-level effects. That result is not solely caused by the new 90% cap; the lack of an itemized loss offset also existed under the prior treatment.
Whether itemizing produces a better complete return cannot be determined from gambling figures alone. It depends on filing status, the applicable standard deduction, all potentially allowable itemized deductions and the rest of the return.
Professional Gamblers Should Not Use This As A Return Calculation
Tax guidance distinguishes recreational Schedule A reporting from the business-reporting path generally associated with professional gambling. Professional status depends on the taxpayer’s actual activity, not a label selected in a calculator.
The reviewed guidance says the 2026 limitation may also affect professional gamblers and wagering-related expenses. The recreational formula does not calculate professional status, business expenses, self-employment tax, estimated-tax obligations, entity treatment or partnership consequences.
A potential professional gambler needs current primary guidance and individualized review rather than the recreational-itemizer output shown here.
Federal Results Do Not Determine State Tax
The calculator covers one simplified federal calculation. State rules may use different definitions, netting rules and deduction limits.
As one bounded example, Monaco CPA’s New Jersey guidance says documented same-year losses may offset winnings within the applicable gambling-income category, subject to a zero floor, with no cross-category offset or carryforward. It also says federal and New Jersey calculations must be performed separately. Review the New Jersey-specific explanation.
That description should not be applied to another state without jurisdiction-specific authority.
H.R. 4304 Has Not Repealed The Cap
Congress.gov displays H.R. 4304, the Fair Accounting for Income Realized from Betting Earnings Taxation Act, at the Introduced stage. The displayed record lists a motion to discharge the committee filed on February 12, 2026. It does not show the bill as having passed both chambers or become law. Check the current H.R. 4304 record on Congress.gov.
Introducing a bill or filing a discharge petition does not change the tax code. Verify later congressional action, public laws and final IRS forms and instructions before filing a 2026 return.
The available support for this worksheet consists mainly of secondary tax guidance rather than complete final filing materials. The calculation is therefore presented as the stated 2026 formula, not as an IRS-approved return calculator.
What The Estimate Leaves Out
Keep four amounts separate:
- Economic result: winnings minus supported losses.
- Taxable gambling income: the amount left after the applicable gambling deduction in the simplified calculation.
- Phantom-income gap: taxable gambling income exceeding positive economic profit.
- Final tax liability: the result of the complete federal and state returns.
The estimated extra tax does not model filing status, progressive brackets, other income, credits, other itemized deductions, alternative minimum tax, withholding, state taxes, self-employment tax or changes to another deduction or limitation.
The worksheet also does not reliably handle nonresident or expatriate taxpayers, foreign gambling, currency conversion, treaty claims, noncash prizes, installment jackpots, prediction markets, shared wagering, multiple jurisdictions or uncertain session accounting.
Use the output as a reproducible arithmetic worksheet and retain it with the underlying records. Verify current law and IRS guidance before filing, and obtain qualified tax advice when classification, substantiation, itemization or state rules could change the result.
