Airdrops: tax classification and treatment

An airdrop delivers tokens without payment. It is classified as income: under Rev. Rul. 2019-24, ordinary income at fair market value when the taxpayer gains dominion and control over the tokens.

Tax treatment

House treatment: income for airdrop.

This mapping comes from the closed CryptoTaxEdge classification taxonomy: every verdict resolves to one category and one of five treatments (disposal, income, non_taxable, expense, needs_review), with a confidence score and review routing when sources disagree.

How the engine reads this shape

The control test does real work here. Tokens pushed to a wallet the taxpayer controls are income on arrival even if unwanted; tokens that must be claimed become income at the claim, when control begins. Worthless or spam airdrops are the practical headache: technically income at a near-zero value, and a disposal later if sold. The engine separates genuine airdrop claims from spam-token dust, flagging the latter as spam identification rather than manufacturing phantom income rows for tokens no one asked for.

Verified rules behind this category

The engine backs this category with 24 verified contract-level rules across 4 chains, each earned from repeated on-chain observation and cross-source agreement rather than a heuristic guess. A small illustrative sample:

Limitations

What this page does not decide. Valuing an illiquid airdrop at receipt can be genuinely hard, and a defensible fair market value is a preparer judgment. Retroactive "points" programs that convert to tokens complicate the receipt date; the engine reports the on-chain claim as the observable event. Confidence is a corroboration signal, not an accuracy percentage: when independent parses of a transaction disagree, the engine returns needs_review with taxable: null rather than guessing.

Frequently asked questions

What tax treatment does this page document?

House treatment follows the CryptoTaxEdge Classification Standard. Categories with no fixed mapping (GAP-3) tell you to read the treatment field on the record rather than infer it from the category name.

Where is the closed vocabulary published?

The versioned Classification Standard at https://cryptotaxedge.com/standard/ enumerates emitted categories and the five-treatment enum. This encyclopedia page is a worked example on top of that Standard.

Are the wire examples still current?

Yes. Each example is verbatim engine output, re-verified on a daily replay against the live engine.
