The 2026 90% Gambling Loss Deduction Rule Explained
A planning overview of the federal rule limiting the gambling-loss deduction to the lesser of 90% of losses or gambling winnings.
Matthew NewmanAuthor and editorial reviewer · Primary sources checked 2026-08-28The 2026 change makes gross recordkeeping more important. If someone tracks only a net result, they may lose the information needed to model the federal limitation.
This page is an educational overview. The application of the law can depend on taxpayer status, session accounting, itemization, expenses, and other return facts.
The rule applies a percentage limit
The federal deduction is limited to the lesser of 90% of wagering losses or wagering gains. A taxpayer with $10,000 of winnings and $10,000 of losses may not receive a $10,000 federal loss deduction under the 2026 rule.
That gap is why “I broke even” and “my taxable gambling amount is zero” are no longer interchangeable assumptions.
Preserve gross wins and gross losses
Keep the source detail that supports both amounts. Do not overwrite the ledger with a single net number after reconciling an account.
W-2Gs, statements, session records, and withholding each answer different questions and should remain available.
State treatment may differ
State rules do not necessarily mirror the federal treatment. Location, residency, and the states shown on forms can matter.
Ask a qualified professional to apply federal and state rules to the complete record set before filing.
Use estimates as questions, not answers
A planning estimate can show how a 90% assumption changes the arithmetic and identify missing records. It cannot determine final tax liability.
Recheck current IRS guidance for the filing year and preserve the assumptions used in any export.
