Polymarket Liquidity Rewards, Maker Rebates and Holding Rewards: How They're Taxed

Polymarket liquidity rewards and holding rewards are most likely ordinary income, valued in dollars when they reach your wallet. They're not trading profit, and they don't wait for a market to resolve. Maker rebates are less clear, because they could be seen either as income or as a reduction in your trading costs. The IRS has not addressed any of these programs, so this is reasoning from general rules, not a settled answer.

OddsFile is software, not tax advice. The IRS has not issued guidance on how prediction-market contracts are taxed, and no guidance addresses Polymarket's rewards. This article explains the options and the sources behind them; a tax professional can tell you which position fits your situation.

The three programs

The holding reward page says the rate is variable and subject to change at Polymarket's discretion, and that the rewards are funded through the Polymarket Treasury. Rebates are funded by taker fees. Check the live pages for current terms.

The general rule

All income is taxable unless the code excludes it, and these aren't excluded. The nearest IRS authority covers staking:

• Rev. Rul. 2023-14 says a cash-method taxpayer includes staking rewards in income in the year they gain dominion and control, at fair market value on that date and time.
• Paschall v. Commissioner, T.C. Memo. 2026-46 is cited by the IRS for the point that staking rewards are income. Advisers such as Jones Day summarize it as taxing the rewards on receipt.
• The Form 1040 digital asset question specifically covers digital assets received as a reward or award.

Liquidity rewards aren't staking, but the logic carries over cleanly. You receive property of a known value, and you can spend it right away.

Program by program

Liquidity rewards look like a payment for a service: you supply quotes, and the venue pays you. Ordinary income at receipt is the natural reading. If quoting is a real business for you, they may belong on Schedule C. See below.

Holding rewards look most like interest on a balance, though they're not interest from a bank. Ordinary income when paid is the straightforward approach.

Maker rebates are harder. They're a partial return of fee money from a fee pool. Two approaches:

A rebate paid from a daily pool can't be easily traced to a particular fill, which favors the income view on practical grounds. Kalshi, by contrast, nets rebates into its P&L figure. There's no ruling either way. Choose one and apply it consistently.

Where it goes on your return

Line 8v appears on the 2025 and the 2026 draft Schedule 1. Your software may label it differently.

Whichever tax treatment you use for your trades, rewards are separate. They aren't gambling winnings merely because you use gambling treatment, though we know of no authority that addresses the point. A preparer who uses gambling treatment throughout may see it differently.

Your basis in the reward

Whatever you include as income becomes your basis. If you receive 12 pUSD worth $12, you have $12 of income and a $12 basis. When you spend it on shares, your cost is $12, and there's no second tax.

Forgetting this causes double taxation, or a phantom gain, if software sees a reward token as zero-cost.

Worked example

A trader earns these in 2026, all ordinary income in the 24% bracket:

The total is added to whatever the trading result is. If their markets lost $3,000 under capital treatment, the $1,200 stays ordinary income and the capital loss offsets it only through the $3,000 annual limit.

When rewards become a business

If you run quoting bots, reward farming is your main goal and it's regular and continuous, it may be a business. That can mean Schedule C and self-employment tax, but it also opens up deductions for real costs; see prediction market expenses. A few dollars from casual limit orders is unlikely to get there. The test is about facts, not labels.

Records to keep

Polymarket's on-chain exchange doesn't send a 1099, so no form will tell you the total. Record:

1. Date and time of each payout, in UTC
2. Token and amount
3. USD value at receipt
4. Which program paid it
5. The wallet that received it

Daily payouts mean up to 365 entries per program. The docs note that earnings in different reward assets should not be simply added together without considering their value, so check what each row was paid in. Small amounts count: there is no minimum for reporting.

FAQ

Are Polymarket rewards taxed when earned or when claimed?

Likely when you have control over them, which for automatic daily payouts is when they land in your wallet.

I earned $40 in rewards. Do I need to report it?

Yes. Income has no minimum. The thresholds you hear about govern when a payer files a form.

Will Polymarket send me a 1099 for rewards?

The international exchange doesn't issue 1099s. See does Polymarket send a 1099?

Do rewards count as capital gains?

Generally no. Receiving them is ordinary income. If you later sell the token for more than your basis, that later difference is a capital gain.
