For a casual gambler, the key difference is the year: on a 2025 federal return, you must itemize to claim losses, and the deduction cannot exceed reported winnings; for tax year 2026, the deduction is further limited to the lesser of 90% of eligible wagering losses or wagering gains. Keep a detailed activity diary and supporting records—Form W-2G alone does not establish your total winnings or losses.
Start with the tax year: the loss limit changes in 2026
The rules below concern U.S. federal individual income tax. Use the rules for the year in which the gambling activity occurred, not simply the year you file the return. The 90% limitation begins in tax year 2026; it does not apply to a 2025 return.

| Tax year | Casual gambler’s reporting and loss rule | Where losses are claimed |
|---|---|---|
| 2025 | Report all winnings as income. If you itemize, eligible losses may be deducted up to the amount of winnings reported. | Schedule A. The 2025 instructions place gambling losses on line 16, limited to winnings reported on Schedule 1, line 8b. |
| 2026 | Report all winnings as income. The allowable loss deduction is the lesser of 90% of eligible wagering losses or wagering gains. | Use the applicable 2026 return instructions and Schedule A mechanics. The 90% ceiling follows the amendment to Internal Revenue Code section 165(d) enacted in Public Law 119-21. |
The IRS’s May 2026 bulletin describes proposed regulations implementing the statutory change, and Publication 505 (2026) gives the taxpayer-facing rule. For a 2026 return, do not simply carry forward the 2025 line instructions; follow the instructions for the return year.
What the 2026 calculation means
For example, suppose a casual gambler has $10,000 in wagering gains and $8,000 in eligible wagering losses during 2026. Ninety percent of the losses is $7,200, which is less than the $10,000 in gains, so the allowable loss deduction is $7,200, assuming the taxpayer otherwise qualifies to claim it. If eligible losses were $14,000 and wagering gains were $10,000, 90% of losses would be $12,600, but the gains cap would limit the deduction to $10,000. These figures illustrate the statutory calculation; they are not a substitute for classifying the activity and expenses correctly.
#1 Best Overall
The two limits do different work. The 90% calculation first reduces the amount of eligible losses that can be considered. The wagering-gains ceiling then prevents the deduction from exceeding gains. In practical terms, calculate both figures for the year and use the lower one. For instance, with $8,000 in eligible losses, 90% is $7,200; if wagering gains were only $6,000, the allowable deduction would be $6,000, not $7,200. Do not apply this calculation to 2025 activity: that year’s casual-gambler rule remains a deduction limited to reported winnings, subject to itemizing.
Report winnings and losses separately
Do not subtract your losses from your winnings and report only the net amount. The IRS’s 2025 Publication 17 states: “You must report the full amount of your gambling winnings as income and claim your losses (up to the amount of winnings) as an itemized deduction.” For a casual gambler, winnings are generally reported on Schedule 1 (Form 1040), and eligible losses are claimed separately on Schedule A if you itemize.
- Add up gross winnings. Include all gambling winnings for the year, not just the amounts shown on tax forms. Use your records to account for the full amount.
- Report winnings as income. Enter them using the applicable Form 1040 and Schedule 1 instructions for that tax year. Do not reduce this income entry by losses or withholding.
- Determine eligible losses. Reconcile your diary and supporting documents, then apply the limit for the year: winnings for 2025, or the lesser of 90% of eligible losses and wagering gains for 2026.
- Claim losses in the appropriate place. For a casual gambler, losses are an itemized deduction on Schedule A, not a subtraction from gambling income. For 2025, Schedule A instructions specify line 16 and tie the limit to winnings reported on Schedule 1, line 8b.
Itemizing matters. A casual gambler who takes the standard deduction cannot claim gambling losses as a separate Schedule A deduction. The loss deduction also cannot create a gambling loss beyond the applicable statutory limit.

Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Repair Windows errors before they cause bigger problemsFix Now →For a simple 2025 illustration, suppose you have $5,000 of gambling winnings and $3,000 of substantiated, eligible losses. You report the full $5,000 as income. If you itemize, your loss deduction may be as much as $3,000, subject to the applicable rules. You do not report $2,000 as the gambling income figure. If your losses were $7,000 instead, the 2025 deduction could not exceed the $5,000 of winnings, even if your records establish greater losses. For 2026, the 90% calculation changes the result: $3,000 of eligible losses produces a preliminary limit of $2,700, which is then compared with wagering gains.
Reporting the full amount and claiming losses separately is important even when the two amounts seem to cancel out. The income figure and deduction are reported in different parts of the return and are subject to different requirements. The fact that a taxpayer had a losing year overall does not itself allow netting away winnings, nor does it establish that all costs or losses meet the deduction rules.
A W-2G is not a complete gambling record
Form W-2G reports certain gambling winnings under reporting rules that depend on the gambling type, amount, and, in many cases, the ratio of winnings to the wager. It is not a record of every winning session or a summary of all activity for the year. IRS Topic 419 says taxpayers must report all winnings, including winnings for which no W-2G was issued.
Federal tax withheld shown on a W-2G is generally claimed as federal income tax withholding on the return. It is not a gambling loss and should not be added to the amount of losses deducted on Schedule A. Keep the form with your tax records and use the return instructions to enter withholding in the appropriate place.

Think of a W-2G as one piece of evidence, not a year-end ledger. It can support the winnings it reports, but it will not necessarily capture winnings that did not meet the applicable reporting conditions. Nor does a W-2G prove the amount of losing wagers. The same separation applies to withholding: tax already withheld is a payment credited on the return, not a wager lost. Keep the form, include its income information in your annual reconciliation, and avoid counting its withholding as either income or a loss deduction.
Keep a diary and evidence for both sides of the calculation
The IRS says taxpayers claiming gambling losses must keep an accurate diary or similar record of winnings and losses and be able to substantiate the amounts. Make the record close to the time of each activity rather than trying to reconstruct an entire year from memory. For each specific wager or gambling activity, record:
- The date and type of activity or wager.
- The name and address, or location, of the gambling establishment.
- The names of other people present at the establishment.
- The amounts won or lost.
Retain independent documents that corroborate the diary. IRS examples include Form W-2G, Form 5754, wagering tickets, canceled checks or substitute checks, credit records, bank withdrawals, casino statements of actual winnings, and payment slips. A document may support one part of the account without proving the whole year: a W-2G, for instance, documents certain reported winnings but does not establish all losses.
Keep enough detail to explain how an annual total was built. A single yearly number such as “gambling losses: $4,000” is much harder to substantiate than dated entries that identify the activity, location, amount, and documents connected with each entry. If an entry represents multiple activities or a trip, preserve the underlying detail rather than relying only on a rounded total. The goal is to let you trace a claimed amount from the return back to the diary and then to supporting evidence.

Choose a recordkeeping method that can be checked
A paper journal, spreadsheet, or another recordkeeping method can work as an organizer if it preserves the required details and can be reconciled to source documents. The method matters less than whether the entries are specific, dated, and supported. A practical log should keep winnings separate from losses, identify the tax year, and let you connect an entry to the related ticket, statement, withdrawal, or other evidence.
When choosing among a paper notebook, spreadsheet, or tax software, ask whether it can capture every diary field, keep winnings and losses distinct, and retain or link images of tickets, statements, or receipts. Also check that it can keep years separate, so the 2025 and 2026 limits are not mixed. No particular format makes an unsupported number substantiated; an organizational tool should make it easier to find the documents that support each entry.
- Record activity as it happens, including losing sessions—not only wins or transactions that generated tax forms.
- Save documents in a way that links them to the diary entry, such as a dated folder or a reference field in a spreadsheet.
- Keep records for each tax year separate. In particular, do not apply the 2026 90% limitation to 2025 activity.
- Reconcile totals before filing. Investigate gaps between your diary, account or casino records, and tax forms rather than treating a form as a complete annual total.
A useful reconciliation has three parts: your own activity log, the corroborating records, and the tax forms you received. Compare the totals rather than assuming any one source is complete. If your log shows a win but no tax form exists, the absence of the form does not remove the duty to report the winnings. If a statement or ticket does not match your entry, resolve the discrepancy or preserve a note explaining the amount you can substantiate. Do not fill gaps by estimating a deduction without support.
Which expenses may be included in losses?
IRS Publication 529 describes gambling losses as the actual cost of wagers plus expenses incurred in connection with gambling, and gives travel to and from a casino as an example. That description does not establish that every cost associated with a gambling trip is deductible. A meal, hotel bill, or other outlay should not automatically be added to losses just because it occurred during a gambling trip.

Publication 529’s gambling discussion was revised in December 2020. Use it as background for the diary and example, but check current return-year instructions for filing mechanics. For substantial or unusual expenses, the available general guidance does not resolve every fact-specific question; keep records and get individualized tax advice before claiming them. Any amount treated as an eligible loss remains subject to the applicable annual limitation.
Keep wager costs and any claimed related expense identifiable in your records rather than rolling all trip spending into one “loss” total. The example of travel to and from a casino is not a blanket approval for every travel cost, and it does not answer how a particular meal, lodging charge, or mixed-purpose trip should be treated. Classification matters because the year’s loss ceiling applies only after identifying amounts that qualify. If an outlay is large, unusual, or difficult to connect directly with gambling, do not assume that its timing alone makes it deductible.
Casual gambling and professional gambling are not interchangeable
The simple Schedule A workflow is for a casual gambler. The IRS’s 2025 Publication 17 says a taxpayer engaged in the trade or business of gambling uses Schedule C. Professional status and the classification of expenses depend on the facts, so do not assume that every frequent gambler is a professional or that casual-gambler filing instructions describe every business activity.
For tax years 2018 through 2025, IRS Publication 525 says professional gambling losses and expenses are limited to winnings. A professional gambler cannot claim a net loss on Schedule C in a loss year, even if other gambling expenses exceed gross gambling income. Beginning in 2026, the amendment to section 165(d) adds the 90%-of-losses ceiling, also limited by wagering gains. A professional gambler should verify the treatment against current-year instructions and get tax help where the activity or expense classification is uncertain.
This distinction affects where the activity is reported and how the records are organized; it is not just a label to choose because it produces a preferred tax result. A person following the casual-gambler approach generally reports winnings as income and claims eligible losses as an itemized deduction. The professional-gambler material discusses Schedule C and the treatment of losses and expenses in that context. Because the facts determine the classification, do not copy the casual Schedule A steps into a business return without checking the applicable instructions.
The dates matter here, too. Publication 525 describes the professional limitation for 2018 through 2025; the 2026 statutory change alters the loss ceiling. A professional gambler with a 2026 return should account for the new 90% rule and the wagering-gains cap under current instructions rather than assuming the earlier period’s wording answers every 2026 question. If the classification of an activity or expense is uncertain, professional assistance can help determine which return treatment applies.

Nonresident aliens generally have a different filing path
Nonresident aliens with U.S.-source gambling winnings generally use Form 1040-NR. IRS Topic 419 says nonresident aliens generally cannot deduct gambling losses on Schedule A, so the casual U.S. resident’s Schedule A approach should not be applied automatically.
The 2025 Form 1040-NR instructions identify special treatment for qualifying Canadian residents: eligible U.S.-source gambling losses may offset U.S.-source gambling winnings, but cannot create a net loss deduction. Treaty eligibility and the type of gambling can affect the result. Nonresident taxpayers should use the applicable Form 1040-NR instructions and treaty guidance for their circumstances.
This is a limited exception, not a general rule for every nonresident or every type of wagering. A nonresident should confirm the filing status, source of winnings, treaty eligibility, and relevant gambling category against the applicable Form 1040-NR instructions. Do not use a resident individual’s Schedule A loss deduction merely because the taxpayer has supporting records; the records do not override the separate nonresident filing rules.

The IRS and Treasury estimated that approximately 670,000 taxpayers claimed an itemized deduction for wagering losses for tax year 2022. They projected that 673,000 taxpayers would take such a deduction for tax year 2026. The latter is a projection, not a count of filed 2026 returns. These figures underscore why the deduction’s recordkeeping and year-specific limits matter, but they do not change the rules for an individual return.
The figures also describe different things: the 2022 number is a retrospective estimate of taxpayers who claimed an itemized deduction, while the 2026 figure is a projection. Neither figure indicates that every person with a gambling loss qualifies to deduct it. A taxpayer still needs to report winnings properly, meet the itemizing requirement for the casual Schedule A path, substantiate claimed amounts, and apply the limit for the year at issue.
Before you file: a focused check
- Confirm the tax year for the activity and use that year’s rules.
- Include all winnings, even when no W-2G was issued, and report gross winnings rather than netting losses against them.
- For a casual 2025 return, claim losses only if you itemize and only up to winnings reported.
- For 2026, calculate 90% of eligible losses and compare it with wagering gains; the deduction is the lower amount.
- Use a diary with the IRS-listed activity details and retain corroborating records for the amounts claimed.
- Check whether professional status, nonresident status, treaty treatment, or unusual expenses change the filing analysis.
As a final cross-check, make sure the income total is gross winnings, the loss figure is supported by the diary and documents, and the deduction is entered in the correct place for your filing path. Confirm that W-2G withholding is treated as withholding, not as a loss. If your facts involve professional activity, nonresident status, a treaty, or expenses beyond wager costs, consult the relevant current-year instructions or a qualified tax professional rather than forcing the facts into the casual gambler example.

Do I have to report gambling winnings if I did not receive a W-2G?
Yes. IRS Topic 419 says to report all gambling winnings, including amounts for which no W-2G was issued. A W-2G covers certain reportable winnings; it is not a complete annual record.
Can I report only my net gambling winnings after losses?
No. Report the full amount of gambling winnings as income, then claim eligible losses separately if you qualify. Do not subtract losses from winnings on the income line.
What records do I need to deduct gambling losses?
Keep an accurate diary or similar record for each activity, including date and type, establishment name and address or location, people present, and amounts won or lost. Retain corroborating documents such as wagering tickets, canceled checks, credit records, bank withdrawals, casino statements, payment slips, and applicable tax forms. A W-2G alone does not substantiate all losses.

For 2025, a casual gambler who itemizes may deduct eligible losses up to reported gambling winnings. For 2026, the deduction is limited to the lesser of 90% of eligible wagering losses or wagering gains. Apply the rule for the year the activity occurred.
Can I include travel, meals, or hotel costs as gambling losses?
IRS Publication 529 describes actual wager costs plus expenses incurred in connection with gambling, and gives travel to and from a casino as an example. That does not establish that every trip expense is deductible. Keep records and get individualized advice for substantial or unusual costs.
Do the Schedule A rules apply to professional gamblers or nonresident aliens?
Not necessarily. The IRS says a taxpayer in the trade or business of gambling uses Schedule C, and professional loss treatment has its own year-specific rules. Nonresident aliens generally use Form 1040-NR and generally cannot deduct gambling losses on Schedule A; qualifying Canadian residents may have special treatment under the 2025 instructions. Check the applicable instructions and treaty guidance.
The Bottom Line
To avoid overstating gambling losses, report all winnings in full, keep a detailed diary backed by documents, and claim only eligible losses under the rule for the activity’s tax year. A casual gambler must itemize for the 2025 Schedule A deduction; for 2026, the cap becomes the lesser of 90% of eligible losses or wagering gains. Professional gamblers and nonresident aliens should check their separate filing rules.
