Airdrop Tax UK: How HMRC Taxes Free Crypto Tokens

July 14, 2026 3 min read

Key Takeaways

  • HMRC taxes airdrops as income only when you take action to receive them — claiming, completing tasks, or referring others. Airdrops that appear in your wallet without any action are not income.
  • The £1,000 trading allowance may cover small airdrop income from claim-based or task-based airdrops, but only if the airdrop is not your main trading activity.
  • For no-action airdrops, CGT applies when you sell, with a cost basis of zero. The full sale proceeds are treated as a capital gain.
  • Track every airdrop with the date received, market value at receipt, the type of airdrop, and the transaction hash — HMRC expects accurate records of all crypto income.
  • The CGT annual exempt amount of £3,000 (2025-26) applies to gains from airdrop sales combined with other crypto disposals.

Airdrops — free tokens distributed to wallet addresses — are taxable events in the UK. The tax treatment depends on the type of airdrop.

Types of Airdrops

TypeHow It Works
Token distributionFree tokens sent to existing holders
Forced airdropTokens appear in your wallet without action
Claim-based airdropYou must claim the tokens
Task-based airdropComplete tasks to earn tokens
Holder airdropBased on holding a specific asset

Tax Treatment by Type

Airdrop TypeTax Treatment
Token distribution (no action needed)No tax until you sell
Claim-based airdropIncome tax at market value when claimed
Task-based airdropIncome tax (trading or miscellaneous)
Holder airdrop (no action)No tax until disposal
Referral airdropIncome tax

The key distinction: if you had to do something to receive it (claim, task, referral), it’s income. If it just appeared in your wallet, it’s not income — but CGT applies on sale.

Bottom Line

Airdrops that require action (claiming, tasks, referrals) are taxable as income when received. Airdrops that appear without action are not income — but CGT applies when you sell, with a cost basis of zero. The £1,000 trading allowance may cover small airdrop income. Track every airdrop with date, value, and type. HMRC expects accurate reporting of all crypto income.

Planning Ahead for Airdrop Tax

The distinction between income and capital gains for airdrops has real consequences for your tax bill. If you are an active DeFi user who regularly receives airdrops, the income tax treatment can be significantly more expensive than CGT — particularly if your marginal income tax rate is 40% or 45%, compared to the CGT rates of 18% or 24%.

One practical approach is to keep a running log of every airdrop you receive throughout the year. Note the date, the token, the GBP value at that moment, whether you took any action, and the transaction hash. When the self-assessment deadline arrives, this log makes the difference between a straightforward return and a frantic weekend of blockchain archaeology.

It is also worth noting that HMRC has become increasingly sophisticated in its ability to trace on-chain transactions. The days of assuming crypto income is invisible to the taxman are long gone. If you have received airdrops — whether you think they are taxable or not — keeping records protects you if HMRC queries your return.

Frequently Asked Questions

Are all airdrops taxable in the UK?

Not all airdrops trigger income tax. If tokens appear in your wallet without you taking any action — for example, a snapshot-based distribution to existing holders — there is no income event. You pay CGT only when you eventually sell those tokens. However, if you claim an airdrop, complete tasks, or refer others, HMRC treats the tokens as income at market value when received.

What is the cost basis for a no-action airdrop?

For airdrops that arrive without any action on your part, the cost basis is zero or the market value at the time of receipt, depending on your chosen accounting method. When you sell, the full proceeds are a capital gain. This is why record-keeping matters — you need the date and GBP value at the time the tokens appeared.

Does the £1,000 trading allowance cover airdrop income?

If your airdrop income qualifies as trading or miscellaneous income and totals less than £1,000 in the tax year, it may be covered by the trading allowance. This typically applies to occasional claim-based airdrops. If your airdrop activity constitutes a trade, the allowance does not apply and all income must be reported.

How do I calculate CGT on airdropped tokens I sell?

Subtract your cost basis from the sale proceeds to find the gain. For no-action airdrops, the cost basis is zero, so the entire sale amount is a gain. For income-taxed airdrops, the cost basis is the market value when you were taxed on them. Offset the gain against the £3,000 CGT annual exempt amount (2025-26) and pay CGT on any remaining gain at 18% or 24% depending on your income band.
