Verified odds, honest tracking, and the tax bill nobody warns you about.

Do I really have to report betting winnings?

Yes. In the U.S., your sports-betting winnings are taxable income — every sport, every book, parlays and futures included — and you’re required to report them on your federal return whether or not the sportsbook sends you a tax form. Winnings count as income in the year you win them.

You can’t simply report your net. You report total winnings as income, and losses are only deductible if you itemize (and only up to your winnings), which is exactly where the new 2026 rule bites.

What’s a W-2G, and where does it come from?

A Form W-2G is a tax form your sportsbook creates, not you. Starting with tax year 2026, one payout triggers it when it’s $2,000 or more and at least 300× your wager. The book files one copy with the IRS and gives one to you, so the IRS knows about that win before you file anything. On payouts over $5,000 at 300×+, the book also withholds 24% for federal tax up front.

Where to find yours: the tax-documents section of your book’s website (not the phone app), by the end of January. Win in person at a casino and they hand you the paper form on the spot.

Never gotten one? That’s normal. Almost no sports bet pays 300× the wager, so most bettors never see a W-2G. But no form doesn’t mean no tax: every dollar of winnings is still taxable and still yours to report, which is why a year-round running total matters.

Do the books’ numbers match yours? Verodd checks.

Every W-2G means the IRS already has the books’ side of the story. Your bet log is your side. The Verodd app compares the two: enter each form and it flags any gap before you file. If the books reported more than you logged, the IRS can see winnings that are missing from your records. And any tax a book already withheld comes straight off your “set aside” number.

When do I actually pay, annually or quarterly?

Most people settle up once a year when they file. But if you have significant winnings with little or no tax withheld, the IRS expects estimated quarterly payments (Form 1040-ES, due roughly mid-Apr, mid-Jun, mid-Sep, and mid-Jan). Skip them and you can owe an underpayment penalty even if you pay in full at filing.

Verodd’s job is to keep a live “set aside $X” number all year, so whichever applies to you, the cash is already waiting.

Closing-line value (CLV) measures whether you beat the market’s final price before a game starts. If you consistently take better numbers than where the line closes, that’s the single strongest signal that you’re a skilled bettor, because short-term wins and losses are mostly variance, but beating the close, repeatedly, is not.

Verodd looks up the independent historical closing line from a licensed odds source to grade each bet, so the number can’t be faked. We call it “verified close, self-tracked entry”: the closing price is verified by us; the price you got is the one you logged. Only verified grades feed your public score and share card, never a self-typed close.
