with the rollover that actually decides whether you can cash out.

How to read a casino bonus
A bonus is only as good as its wagering requirement, game weighting and max cashout. Our rule of thumb: a 100% match at
25x beats a 500% match at 60x almost every time, and a no-wagering free-spins offer beats both because the
winnings are real cash. Below, the standout offers on our list:
Best no-wagering: BetOnline (100 free spins) and Super Slots (300 free spins) — winnings are cash.
Best match value: Ignition 300% up to $3,000 at a low 25x rollover.
Biggest crypto bonus: Wild.io 400% up to $10,000 (crypto casinos page).
Best for high rollers: Slots of Vegas 375% + spins up to $25,000.
Do you pay taxes on offshore casino winnings?
Yes. This is the single question almost every competitor skips, so here is the straight answer. Under US federal
law, all gambling winnings are taxable income — whether you win at a Las Vegas cage, a state-regulated app, or an
offshore site licensed in Curaçao. The offshore label does not make winnings tax-free.
Where it goes on your return: gambling winnings are reported as "Other income" on Schedule 1, line 8b of Form 1040.
No W-2G from offshore books: US-regulated casinos issue a Form W-2G on large wins and may withhold 24% federally.
Offshore operators are outside the IRS reporting system, so they do not issue a W-2G and do not withhold —
but the obligation to self-report is entirely yours.
Recordkeeping: keep a log of deposits, withdrawals, session wins/losses and dates. If you itemize, gambling
losses are deductible up to the amount of winnings (Schedule A).
State tax: most states also tax gambling income at the state rate; a handful (e.g. Texas, Florida, Nevada) have
no state income tax, so only the federal obligation applies there.

Casino bonuses — FAQ
What is the best casino bonus for US players?
Judge by wagering, not headline size. BetOnline's 100 free spins with no wagering and Super Slots' 300 no-wagering spins are the best real value because winnings are cash, not locked bonus funds. For a match bonus, Ignition's 300% up to $3,000 at a low 25x is our top pick.
What does wagering requirement mean?
It's how many times you must bet the bonus (and sometimes deposit) before you can withdraw. A 100% up to $1,000 at 25x means you wager $25,000 before cashing out bonus winnings. Lower is better.
Are no-deposit bonuses worth it?
They're a free look at a casino with no risk, but come with high wagering and low max cashout. Treat them as a trial, not a payday.
Play responsibly
Gambling is entertainment, not an income source, and offshore operators are not part of any US state self-exclusion program — you must use each operator's own deposit-limit, cool-off and self-exclusion tools. If gambling stops being fun, get free, confidential help 24/7:
You must be 21 or older (18+ at some operators) to play. Gambling winnings are taxable income under US federal law and most state laws — see our tax guidance below. We are not a tax adviser; consult a professional.
