Airdrops and free distributions: how they are taxed

The DGT has addressed the airdrop within broader rulings on crypto-asset operations. The strong authority is V0648-24, already with binding effect and a dedicated section on airdrops, which classifies the free distribution of tokens as a capital gain not arising from a disposal, included in the general base of personal income tax (IRPF) at its market value on the date of receipt. Along the same lines, though as a non-binding general ruling, is 0018-23, which treats the airdrop in general terms within a multi-operation scenario. It should be noted that V1948-21, which also places these free additions of value in the general base, in fact resolves a different scenario: the receipt of crypto-assets as consideration for online commercial activities. It is not, therefore, an airdrop in the strict sense, and that difference matters, because it is precisely the presence of an underlying activity of the recipient that may shift the classification.

Let us fix this point precisely from the outset, because it concentrates the two most common errors: where the income is taxed and what the acquisition value of the token received is.

The conceptual error: “I didn’t buy it, so I don’t have to report it”

That reasoning is incorrect. The fact that nothing was paid for the token does not eliminate the income; what it does is shift the focus to the market value of what is received. If tokens worth €500 are received, €500 of value have been added to the taxpayer’s net worth. That amount is taxed at the moment of receipt and, from then on, becomes the token’s tax acquisition value for a later disposal.

It is worth insisting on this second aspect, because it is where popular commentary most often goes wrong. The value on which tax is paid on receiving the airdrop is not zero: it is the market value on the date of receipt, and that same value is then deducted as cost when the token is sold. Otherwise, the same income would be taxed twice.

Step-by-step example

1,000 tokens are received and, on the date they are genuinely placed at the taxpayer’s disposal, their market value is €0.50 per unit. At that moment, €500 are included as a capital gain in the general base. If those tokens are later sold for €5,000, the additional income is a capital gain arising from a disposal of €4,500 (5,000 − 500), which is now included in the savings base. The value on which tax was paid on receipt (€500) operates as the acquisition value, not as zero.

Hard forks: a distinct question

An airdrop should not be equated without more with a hard fork (the splitting of a chain into two). In a hard fork, it is necessary to analyse whether a genuinely new and independent asset arises, when it is placed at the taxpayer’s disposal and how it should be valued. In the absence of a specific ruling covering every scenario, the analogy with the airdrop may be useful, but it should not be presented as a settled rule.

Types of airdrop and their classification

Both promotional and retroactive airdrops share the logic of a free acquisition. Unless there is employment, professional or business consideration that alters the classification, the receipt of the token is treated as a capital gain not arising from a disposal, at its market value at the relevant moment. The classification would shift to employment income or income from an economic activity only where the airdrop in fact remunerated a service provided.

The DGT sets the boundary: if obtaining the token requires participation amounting to the self-employed organisation of means with the intention of taking part in the market —not mere holding or a single click—, the income may be reclassified as income from an economic activity, in the general base and with the corresponding census-registration and VAT obligations, rather than as a capital gain. Airdrops that reward active promotional tasks are the risk zone.

What if the token has no price at the time of the airdrop?

If there is no liquid market or no reliable reference on the date of receipt, the problem is mainly evidentiary and valuation-related. In that case it is advisable to document the methodology used, the existing liquidity and the first reasonably reliable reference, rather than automatically assuming that the value is zero. Assigning a value of zero for convenience is, moreover, risky: it may shift all the taxation to the moment of sale and make the declared figure harder to defend.

Timing of recognition and documentation

The timing of recognition must be linked to the moment the tokens are genuinely deemed received or placed at the taxpayer’s disposal. It is advisable to keep screenshots, statements, transaction identifiers (txid), the terms of the programme and the euro-valuation criterion used. Without that traceability, the defence of the return is considerably weakened.

Let us recall, finally, that all of the foregoing presupposes tax residence in Spain. For non-residents (non-resident income tax, IRNR) and for those covered by the inbound-expatriate regime of Article 93 LIRPF, the treatment differs and calls for its own analysis.
