Never cashed out your crypto? You may still have made a taxable disposal

Selling crypto for pounds isn't the only transaction that can matter for tax. Finbooks calculates your gains and losses and shows you what your crypto activity means for your tax position.

No pounds involved doesn't mean no tax involved

  1. 1

    1 ETH → you bought crypto

    Holding crypto alone doesn't generally create a Capital Gains Tax disposal.

  2. 2

    2,500 USDC → you swapped it

    Exchanging one cryptoasset for another can be treated as disposing of the first asset.

  3. 3

    £0 cashed out but a disposal still happened

    The fact that you never converted your crypto into pounds doesn't necessarily change the tax treatment.

HMRC looks at disposals. Not just cash withdrawals.

One crypto-to-crypto trade may be easy enough to remember.

Years of trading are different.

If you've moved between BTC, ETH, stablecoins and other tokens across several exchanges and wallets, your history may contain hundreds or thousands of transactions, and taxable disposals can be hidden among them.

Your crypto history tells the whole tax story. Finbooks reconstructs it.

Finbooks brings together your activity across exchanges, wallets and blockchains to reconstruct your complete crypto transaction history.

It identifies the transactions relevant for UK tax, applies the appropriate HMRC rules and calculates the gains, losses and income that contribute to your overall tax position.

So instead of manually reviewing years of transactions, you can see what your crypto activity actually means for your Self Assessment.
