Key Changes to 2026 Gambling Tax Law
The 'One Big Beautiful Bill Act' introduced significant changes to gambling taxation starting January 1, 2026:
90% Loss Deduction Cap
You can only deduct up to 90% of your gambling losses (previously 100%). This creates 'phantom income' equal to 10% of your winnings.
Phantom Income Effect
Even if you broke even or lost money gambling, you'll owe taxes on 10% of your total winnings. Example: $50,000 in winnings and $50,000 in losses = $5,000 taxable income.
W-2G Threshold Increased
The W-2G reporting threshold increased to $2,000 (adjusted for inflation from $1,200). Casinos and sportsbooks must report winnings above this amount to the IRS.
Must Itemize to Deduct
To deduct ANY gambling losses, you must itemize deductions. If you take the standard deduction, you pay taxes on your full winnings.
Applies to Professional Gamblers
Professional gamblers who file Schedule C are also subject to the 90% cap. The only exception is for trade or business expenses unrelated to wagering.
IRS Recordkeeping Requirements
The IRS requires detailed records to claim gambling loss deductions:
Daily Gambling Log
Keep date, location, type of gambling, and amounts won or lost for each session
Documentation
Save all W-2G forms, receipts, tickets, and statements from establishments
Session Details
Record establishment names, addresses, table/machine numbers, and witnesses
Bank Records
Keep bank statements, credit card records, and electronic payment confirmations
Contemporaneous Records
Document activity as it happens - retroactive logs may not be accepted by IRS

Start Tracking for FreeShould You Itemize or Take the Standard Deduction?
To deduct gambling losses, you MUST itemize. Here's how to decide:
Standard Deduction (2026)
- • Single: $16,100
- • Married Filing Jointly: $32,200
- • Head of Household: $24,250
When to Itemize
- • Your gambling losses (plus other itemizable deductions) exceed your standard deduction
- • You have significant winnings that would be fully taxable without loss deductions
- • You have other itemizable deductions (mortgage interest, charitable contributions, state taxes)
Example
Single filer with $20,000 in winnings and $18,000 in losses. Standard deduction: $16,100. Should they itemize?
If they take the standard deduction, they pay tax on the full $20,000 in winnings. If they itemize, they can deduct 90% of losses ($16,200), paying tax only on $3,800. Itemizing saves thousands in taxes.
Professional Gambler Considerations
If gambling is your primary income source, special rules apply:
Schedule C Filing
Professional gamblers report income on Schedule C (business income), not as 'Other Income.'
90% Cap Still Applies
Even professionals are subject to the 90% loss deduction cap. Only non-wagering business expenses (travel, research, subscriptions) are fully deductible.
Self-Employment Tax
Professional gambling income may be subject to self-employment tax (15.3%), unlike casual gambling income.
Substantiation Required
You must prove gambling is your primary income and that you approach it as a business, not a hobby.
The distinction between professional and casual gambler is complex. Consult a tax professional if you have significant gambling income.

Frequently Asked Questions
Does the 90% cap apply to all types of gambling?
Yes, the 90% loss deduction cap applies to all forms of gambling: casino games, sports betting, poker, horse racing, and even fantasy sports if considered gambling in your state.
Can I still deduct 100% of losses if I'm a professional gambler?
No. Professional gamblers are also subject to the 90% cap on gambling losses. Only non-wagering business expenses (like travel, research tools, or subscriptions) can be fully deducted.
What if I broke even or lost money overall?
You'll still owe taxes on the 'phantom income'—10% of your total winnings. Example: $30,000 in winnings and $35,000 in losses = $3,000 taxable income (you can only deduct $27,000 of losses).
What happens if I don't itemize deductions?
If you take the standard deduction, you CANNOT deduct ANY gambling losses. Your entire winnings amount becomes taxable income.
Do state taxes follow the same rules?
State tax laws vary widely. Some states have their own gambling tax rules. This calculator covers federal taxes only—consult a local tax professional for state-specific guidance.
When does the 90% cap take effect?
The 90% loss deduction cap applies to tax year 2026 and beyond (gambling activity on or after January 1, 2026). Your 2026 taxes still allow 100% loss deductions.
What records do I need to keep?
The IRS requires: (1) Date and location of gambling, (2) Type of gambling, (3) Amounts won and lost per session, (4) W-2G forms, (5) Receipts, tickets, and statements from gambling establishments.
Can I deduct losses from previous years?
No. Gambling losses can only be deducted against gambling winnings in the same tax year. You cannot carry losses forward or backward.
