If you received free tokens through an airdrop, the IRS considers that income. Revenue Ruling 2019-24 establishes that airdrops resulting from a hard fork are ordinary income at fair market value on the date you gain dominion and control over the new tokens. The same principle applies to promotional airdrops, governance token distributions, and retroactive airdrops from DeFi protocols.
When Airdrops Become Taxable
An airdrop is taxable when you have the ability to transfer, sell, or otherwise dispose of the tokens. For hard fork airdrops, this is typically when the new blockchain is functional and the tokens are accessible in your wallet. For protocol airdrops — like the Uniswap UNI distribution or Ethereum Name Service ENS airdrop — the taxable moment is when you claim the tokens.
Valuation Challenges
Airdropped tokens often have no established market price when received. If the token is listed on an exchange at the time of receipt, the exchange price determines fair market value. If no market exists, valuation requires estimation based on comparable tokens, the size of the distribution, and any available market data. Documentation of the valuation methodology is critical in case of audit.
The Scale of the Problem
Active DeFi participants may have received dozens of airdrops across multiple protocols and chains. Each one is a separate income event requiring reporting. Many occurred in periods of high token prices, creating substantial income that may not have been reported. The aggregate unreported income from airdrops across the crypto ecosystem is enormous, and the IRS is aware of it.
Correcting Unreported Airdrops
If you received airdrops and did not report them, the correction process involves determining the fair market value at the time of receipt, calculating the resulting tax liability, and filing amended returns or delinquent returns that include the income. In many cases, reasonable cause arguments for penalty abatement are strong — the tax treatment of airdrops was uncertain for years, and many tax professionals gave incorrect advice.
