Sold £10,000 of investments? You didn't necessarily make £10,000

Finbooks brings together your shares, ETFs, bonds and crypto to calculate what you actually gained and what you may actually owe HMRC.

7-day free trial. No credit card required.

Total capital gains label connected to icons of several cryptocurrencies and traditinal finance platforms.

Three numbers. Three very different meanings.

  1. 1

    £10,000 - Sale proceeds

    The total amount you received when you sold the investment.

  2. 2

    £3,000 - Capital gain

    If you originally acquired it for £7,000 and dispose of it for £10,000, the simple difference is £3,000 before considering other relevant costs or tax rules.

  3. 3

    Tax due = ?

    Your taxable position can depend on much more than that single transaction.

Your tax bill isn't calculated one investment at a time

Complex management label surrounded by scattered icons of different cryptocurrency and exchange platform logos.
