Are crypto airdrops taxable?
Generally yes. An airdrop received into your control is ordinary income at its fair market value when you gain dominion and control over the tokens. The exception is unsolicited spam and address-poisoning tokens, which are excluded from the books rather than treated as income. CryptoTaxEdge separates the two on the wire: airdrops classify as income, and spam is served as an identification row, free on every plan.
Key takeaways
- An airdrop received into your control is ordinary income at fair market value when you gain dominion and control (the Rev. Rul. 2019-24 timing frame).
- The income recognized at receipt sets the cost basis; a later sale is a separate disposal.
- Spam and address-poisoning tokens are excluded from the books under the house position, never treated as income.
Income when you gain dominion and control
The house treatment follows IRC §61: an unsolicited token distribution received into the taxpayer's control is ordinary income at fair market value on receipt. Rev. Rul. 2019-24, issued for airdrops following hard forks, supplies the timing frame practitioners apply more broadly: income arises when the taxpayer can exercise dominion and control, meaning the ability to transfer, sell, or otherwise dispose of the tokens. Tokens you cannot yet move are not income until you can, and an airdrop that must be claimed is income at the claim, because that is when control begins.
Basis and the later sale
The amount recognized as income sets the cost basis: fair market value at the moment of dominion and control. A later sale or swap of the airdropped tokens is a separate disposal measured against that basis, with the holding period running from receipt. Capturing the receipt-time value is what makes the later disposal computable; reconstructing it years afterward is much harder than recording it while the transaction is fresh.
Spam and address-poisoning tokens are not income
Anyone can send tokens to any address, so wallets accumulate unsolicited transfers: spam mints and address-poisoning transfers designed to imitate real counterparties. Treating every unsolicited receipt as income would make a taxpayer's income a function of strangers' behavior. The house position draws the line at identification: a transfer identified as spam or address poisoning is represented under the spam category and excluded from the books rather than treated as an income event. Naming these rows requires no tax judgment, so they are served free on every plan and never counted as billable classifications.
How the wire represents an airdrop
Airdrops are served under the airdrop category with the income treatment; the Classification Standard does not list the category as a grey area, so no alternate position is carried on the record. Spam is a separate category clamped to the non-taxable treatment, so a consumer branching on treatment never books strangers' junk as income. The review contract is unchanged: anything the engine will not assert routes to needs_review with taxable null.
Frequently asked questions
Do I owe tax on an airdrop I never claimed?
Not until dominion and control exists. An airdrop that must be claimed becomes income at the claim, because that is when the ability to transfer or sell begins. An allocation sitting unclaimed that you could take raises the harder timing question; the test is the ability to dispose, and the claim is usually the provable moment.
What if an airdropped token has no market or cannot be sold?
Income is measured at fair market value at receipt, and a token with no functioning market puts real pressure on that number. If transfer restrictions genuinely prevent disposal, dominion has arguably not arrived yet. Where a value must be set, document how it was determined; a thin market is a valuation problem, not an exemption.
Are unsolicited spam tokens taxable income?
No, under the house position. Treating every unsolicited receipt as income would make a taxpayer's income a function of strangers' behavior, so a transfer identified as spam or address poisoning is excluded from the books rather than treated as an income event. The work is the identification, and those rows are served free. The full analysis is in Are unsolicited spam tokens taxable income?
