Are airdrops taxable?
Short answer for US taxpayers: yes, generally. The IRS treats airdropped tokens as ordinary income at their fair market value when you gain control of them, and selling later triggers a separate capital gain or loss. Other countries treat drops differently, and the details move, so treat this page as general information rather than tax advice.
The US treatment
IRS guidance from 2019 (Rev. Rul. 2019-24) established that new tokens received via airdrop are income when the taxpayer has dominion and control, meaning you can transfer or sell them. The amount is the token's fair market value at that moment, which becomes your cost basis. Sell later for more and the difference is a capital gain; sell for less and it's a loss against that basis.
Control matters in practice. Tokens that require an active claim are generally treated as income when claimed, not when the snapshot happened. A large allocation claimed during a price spike can create a tax bill bigger than the tokens' value by the time you sell, which is a real risk with volatile launches.
Elsewhere is genuinely different
The UK's HMRC distinguishes drops received for doing something (taxable as income) from truly unsolicited ones (taxed only on disposal). Australia generally treats airdrops of established tokens as ordinary income but has a separate rule for initial allocations. Germany can treat some passive receipts as tax-free after a holding period. If you're outside the US, check your local authority's crypto guidance rather than assuming the US rules.
Records worth keeping
For every claim, record the date, the token amount, and the market price at claim time; that's your income figure and your basis in one row. Airdropped.link's eligibility reports help reconstruct what you received and when, which is most valuable at tax time when the claim happened months earlier.
