Polymarket Taxes Guide (2026)
How to report Polymarket profits and stay compliant with tax law. Treatment varies by country, and crypto adds extra considerations. Here is what you need to know for the 2026 tax year.
Tax Treatment by Country
United States
Capital Gains + Gambling Income
IRS treats prediction market profits as gambling winnings (reported on Schedule 1) or potentially as short-term capital gains. You can deduct losses up to winnings.
United Kingdom
Generally Tax-Free
HMRC typically treats betting/gambling winnings as tax-free for casual bettors. Professional traders may face income tax.
Canada
Usually No Tax
CRA generally doesn't tax gambling winnings unless you're a professional. Crypto conversion may trigger capital gains.
Australia
Generally Tax-Free
ATO doesn't tax recreational gambling winnings. Professional gamblers pay income tax. CGT may apply on crypto.
Germany
Crypto CGT Rules
Gambling winnings tax-free, but crypto held <1 year is taxed as income. Hold USDC >1 year for tax-free treatment.
* Professional traders and frequent traders may be taxed differently. Crypto-to-fiat conversions may have separate tax implications.
How to Report Taxes
Track All Trades
Record every buy and sell transaction. Note the date, amount, price, and market name.
Calculate Net P&L
Sum up all profits and losses for the tax year. Many jurisdictions let you offset losses.
Track USDC Conversions
When you convert USDC to fiat, that may also be a taxable event. Record exchange rates.
File Correctly
Report on the appropriate form based on your country. Consider using crypto tax software.
USDC and Crypto: Tax Events to Know
Buying USDC (fiat to stablecoin)
Converting USD to USDC is generally not a taxable event because USDC is pegged 1:1 to the dollar and the fair market value does not change at acquisition. Most jurisdictions treat this as a currency exchange with no gain or loss.
Trading on Polymarket (USDC in, USDC out)
Each resolved market position is a potential taxable event. Your cost basis is the USDC you paid for shares. Your proceeds are the USDC received on resolution. The difference is your gain or loss for that position. In the US, this is typically short-term (ordinary rates) since most markets resolve within a year.
Converting USDC back to fiat
Because USDC maintains a 1:1 peg, converting it back to USD on a regulated exchange typically results in no additional gain or loss beyond what was already recognized from the market positions themselves. However, if you acquired USDC at a slight discount or premium (e.g., via a DEX during a depeg event), the difference could trigger a taxable event. Keep records of the rate at acquisition.
Cost basis tracking method
The US IRS allows several accounting methods: FIFO (first in, first out), LIFO, or specific identification. For USDC which is typically held at stable value, the choice of method rarely matters. For other crypto assets you may hold, FIFO is the default if no method is elected. Document your chosen method and apply it consistently across the tax year.
Polygon gas fees
Polyfollow sponsors gas fees for all copy trades, so you do not pay gas directly. If you interact with Polymarket directly and pay MATIC for gas, those fees may be deductible as a cost of the transaction in jurisdictions that allow it, reducing your net gain. Keep records of any gas paid.
Frequently Asked Questions
Do I have to pay taxes on Polymarket profits?
In most countries, yes. In the US, prediction market profits are taxable as gambling winnings or capital gains. Some countries like the UK and Canada may not tax casual gambling winnings. Always check your local laws.
How does the IRS treat Polymarket?
The IRS hasn't issued specific guidance on prediction markets. Most tax professionals treat it as either gambling (Form 1040 Schedule 1) or short-term capital gains (Form 8949). Wins and losses are netted annually.
Can I deduct my Polymarket losses?
In the US, gambling losses can be deducted but only up to the amount of your winnings. You cannot use gambling losses to reduce other income. Keep detailed records to support deductions.
Is withdrawing USDC a taxable event?
Moving USDC isn't taxable. However, converting USDC to USD (or other currencies) may trigger a taxable event if USDC's value changed since you acquired it. In practice, USDC is usually 1:1 with USD.
What records should I keep?
Keep records of all deposits, withdrawals, trade confirmations, and market resolutions. Screenshot your trade history regularly. This documentation is essential if audited.
Do I need to report small profits?
Technically, yes. In the US, all income is taxable regardless of amount. However, enforcement focus is typically on larger amounts. Always consult a tax professional.
