Liquidity mining rewards are tokens a protocol pays you for supplying liquidity, on top of the trading fees the pool already earns. They are an incentive, usually paid in the protocol's own governance token, and they are separate from the pool position itself.
A protocol that wants deeper liquidity pays people to provide it. You deposit into a pool, stake the resulting LP token in a rewards contract, and the protocol emits its token to you over time. Rates get quoted as an APR and move with the emission schedule and the total amount staked against it.
Two streams come out of the same position and they behave differently. Trading fees accrue inside the pool and raise what your position redeems for. Reward tokens are paid out to you as new property.
Some rewards land in your wallet automatically. Others sit in the contract until you claim them, and that distinction matters for timing. A high advertised APR can also leave you behind once impermanent loss is taken into account, so the headline rate is not the return.
As ordinary income under most readings, at the fair market value of the tokens when you gain control of them.
The IRS has not issued guidance on liquidity mining. The closest published position is Revenue Ruling 2023-14, which holds that staking rewards are included in gross income when the taxpayer gains dominion and control over them. Liquidity mining is not staking, but that dominion and control test is the reasoning most practitioners apply to reward tokens more broadly.
Timing follows from the same test. Where rewards accrue inside a contract and cannot be moved until claimed, the argument is that income arises on the claim. Where they arrive in your wallet and can be sold immediately, income arises then.
The value recognised as income becomes your cost basis in those tokens. Sell them later and you have a capital gain or loss measured from that figure, which is a second and separate taxable event.
Reward tokens are often new, thinly traded, or listed on a single venue with an unreliable price. Software either imports them at zero, which understates income now and overstates the gain later, or picks up a price from a market with almost no volume behind it. Rewards claimed months after they accrued get valued on the wrong date. Each of those errors carries through to the eventual disposal, so the mistake gets counted twice.
