FAQ

Is Polymarket legal in my country?
Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Polymarket Tax UK has a different geo footprint.
How are winnings taxed?
Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.
What happens during a tax audit?
You're responsible for documenting your trades. Polymarket Tax UK exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.
Is there a withdrawal cap?
No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).
What if regulation changes?
If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Tax UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
