Capital gains needs reporting to HMRC if the net chargeable gains exceed the annual exempt amount. In the current tax year 2024/25, gains need to be reported if the gains exceed £3,000, or if the total proceeds of all disposals exceed £50,000.

Gains can be reported to HMRC in the Self Assessment Tax Return or using the ‘Real time capital gains tax service’. The idea of the ‘Real time capital gains tax service’ is that you don’t wait until the end of the tax year to declare the gain and pay the tax. However, it is unlikely to be appropriate where there are many disposals in a tax year.


The Recap crypto tax report provides a summary of all the relevant information to be included on your annual Tax Return. The intention is that you pass our report to your accountant and they will be able to complete the Tax Return and advise on your tax position, based on your specific circumstances.

If you don’t already file a Self Assessment Tax Return, you need to notify HMRC that you have capital gains to report by 5 October, after the end of the tax year. You can do this at https://www.gov.uk/log-in-file-self-assessment-tax-return/register-if-youre-not-self-employed. HMRC will issue you with a Notice to File a Tax Return and you should chase this if it is not received.

You need to submit the Tax Return to HMRC by 31st January after the end of the tax year to avoid late filing penalties. A tax year runs from 6 April to 5 April.

For example, if you made a disposal on 4 April 2024 (or started to receive income in the tax year ended 5 April 2024), this falls in the tax year ended 5 April 2024 and you need to register for Self Assessment with HMRC by 5th October 2024 and submit the tax return by 31st January 2025.

Late filing penalties increase significantly over time and may be based on the tax due after 6 months so it's important to be file and pay on time.
