DeFi yield farming generates multiple taxable events. Yields (interest, fees, liquidity mining rewards) are ordinary income at receipt under IRC §61. LP token swaps may or may not be taxable depending on which legal theory applies — there is no IRS guidance as of May 2026, so the AICPA recommends treating LP swaps as taxable dispositions to be safe. Governance tokens received as rewards are ordinary income at fair market value; airdrops with no value at receipt take a $0 cost basis.
Why Yield Is Ordinary Income
Under IRC §61, "gross income means all income from whatever source derived" — this includes interest, fees, rewards, and yields earned in DeFi. The AICPA Digital Asset Resource Guide (2023 update) and IRS Notice 2014-21 both treat DeFi yield as analogous to interest or property income at fair market value at receipt. Whether you earn USDC interest on Aave, fee revenue from Uniswap LP, or boosted CRV rewards from Convex, the USD value at receipt must be reported on Schedule 1 (or Schedule C if rising to a trade or business).
LP Token Swap: Two Views
When you deposit ETH + USDC into Uniswap V2 and receive an LP token, there are two competing views: (A) Disposition View — you swapped two assets for one (the LP token), triggering capital gain/loss on the deposited assets. Cost basis of the new LP token is its USD value at receipt. (B) Nothing-Happened View — you retain economic ownership; the LP token is just a wrapper / receipt. No taxable event. The AICPA's 2023 Digital Asset Resource Guide recommends View A (taxable disposition) for safety. The IRS has not ruled. As of 2026, the conservative position is to treat LP swaps as taxable dispositions.
Governance Token Treatment
Governance tokens (UNI, CRV, AAVE, COMP) received through airdrops, liquidity mining, or retroactive rewards have FMV at receipt as ordinary income. If the token has no market value at receipt (true zero — illiquid, no trading), cost basis is $0 and the full sale price becomes capital gain when sold. Track timestamp + USD value at receipt for every claim — without records, the IRS may impute fair value from later trades. Airdrops are treated under IRS Rev Rul 2019-24 and CCA 202444009.
Common DeFi Tax Mistakes
(1) Skipping LP swap reporting — Many DeFi users ignore LP swaps. The AICPA conservative position is they're taxable; an IRS audit may apply this view retroactively. (2) Missing yield reports — DeFi protocols don't issue 1099s; you must self-track. (3) Wrong basis on governance tokens — failing to record FMV at receipt means double tax later. (4) State tax oversight — California, New York, and other states tax DeFi income at full ordinary rates. (5) Impermanent loss confusion — impermanent loss is not a deductible loss until you withdraw and realize it as a capital loss. (6) Wrapped token swaps — wrapping ETH to wETH is conservatively treated as a taxable exchange under Rev Proc 2024-28 starting 2026.
