Can I deduct gambling losses on my taxes?

Only if you itemize deductions on Schedule A. Gambling losses are deductible up to the amount of your gambling winnings, but you cannot use them to create a net loss. If you take the standard deduction ($15,000 single / $30,000 MFJ in 2025), you get zero benefit from your losses.

Do I have to report gambling winnings under $600?

Yes. All gambling income is taxable regardless of whether you receive a W-2G form. The $600 threshold (or $1,200 for slots) only determines whether the casino or app is required to report it to the IRS. You are always required to report it yourself.

What is the tax rate on gambling winnings?

Gambling winnings are taxed as ordinary income at your marginal tax rate. There is no special reduced rate. For a taxpayer in the 24% bracket, every $1,000 in net winnings costs $240 in federal tax, plus any applicable state tax.

Gambling Taxes: The House Always Wins (And So Does The IRS)

Sports betting is exploding. But did you know you can't net your wins and losses unless you itemize? The harsh reality of gambling taxes.

Last updated on February 21, 2026

You bet $1,000 on the Chiefs. You win $2,000. Next week, you bet $2,000 on the 49ers. You lose $2,000. Net Profit: $0. Taxable Income: $2,000.

Wait, what? Welcome to the logic-defying world of gambling taxes.

Key Takeaways

Casual Gamblers: Must report ALL winnings as income. Can only deduct losses if they Itemize (Schedule A).
The Standard Deduction Trap: If you take the Standard Deduction, you pay tax on winnings but get ZERO deduction for losses.
The W-2G: Casinos/Apps send a form if you win big (usually > $600 or > $1,200 for slots).
Professional Status: Pros can deduct losses on Schedule C, but the bar to qualify is extremely high.

The “Session” Rule

Technically, every “session” stands alone.

Slot Machine: Every spin is not a session. A continuous period of play is.
Sports Betting: Each bet is often treated distinctly.

The Horror Story

Imagine you are a high-volume bettor.

You win $500,000 over the year.
You lose $510,000 over the year.
Net: You lost $10,000.
Tax Return: Your AGI increases by $500,000.
- This might disqualify you from Roth IRAs, Child Tax Credits, and financial aid. If you are unsure how AGI thresholds work, see the AGI vs MAGI glossary.
- You can deduct the $500,000 loss on Schedule A (if you itemize), but you still lost all those credits based on AGI.
- And you might owe state taxes if your state doesn’t allow gambling loss deductions (like Connecticut or Ohio in some years).

The Itemizing Decision

The gambling loss deduction only exists on Schedule A. If your total itemized deductions (state taxes, mortgage interest, charity, gambling losses) do not exceed the standard deduction --- $15,000 for single filers or $30,000 for married filing jointly in 2025 --- you are stuck paying tax on your gross winnings with no offset. For the mechanics, review the itemized deduction glossary.

This creates a perverse outcome: a casual bettor who wins $5,000 and loses $5,000 could owe over $1,000 in federal tax on zero actual profit.

Reporting on Your Return

All gambling income appears on Line 8b of Form 1040 as “Other Income.” If you itemize, gambling losses go on Schedule A. Keep a detailed log of every session: date, location, type of wager, amounts won and lost. The IRS can and does challenge gambling loss deductions that lack contemporaneous records.

If you want to estimate the actual tax impact before you place big bets, use your marginal tax rate rather than your effective rate.

Advice: If you aren’t a pro, keep your betting volume low. The tax friction can bankrupt you even if you break even at the tables.
