HMRC expects crypto investors to report any capital gains, losses or crypto income by January 31st 2023. Find out how to report your crypto taxes to HMRC before the deadline.
HMRC have made it very clear that UK crypto investors need to report and pay taxes on their crypto investments. They’re sending warning letters to investors they believe to be wrongly reporting their crypto gains or income.

Don’t worry - we’ve done the research to get all your UK crypto tax questions answered. Learn how to report your crypto to HMRC in 5 simple steps.
How to report crypto to HMRC
You’ll report all your crypto as part of your Self Assessment Tax Return. You’ll report income from crypto in the Self Assessment Tax Return (SA100) and you’ll report any capital gains or losses from crypto in the Self Assessment: Capital Gains Summary (SA108). You need to file your Self Assessment Tax Return online with the HMRC by January 31st 2023. The deadline for paper tax returns is the 31st of October 2022.
Any crypto investor who made more than £1,000 in crypto income or more than £12,300 in crypto capital gains mustsubmit a Self Assessment Tax Return to HMRC.

If you’re submitting your Self Assessment Tax Return by post - you can skip this step and go straight to step 3. Keep in mind you have an earlier deadline of the 31st of October.
If you’ve registered to file a Self Assessment Tax Return online before - you don’t need to do this again. Just sign in.
For crypto investors who haven’t filed a Self Assessment Tax Return online before - you need to register by the 5th of October 2022. The steps are slightly different depending on whether you’re self-employed or not.
If you're self-employed, sign into your business tax account and add Self Assessment. You'll need your Government Gateway user ID and password to do this - so you might need to create one. You'll get a letter with your Unique Taxpayer Reference within 10 days (or 21 days if you're abroad). You'll get a second letter with the activation code for your account. Once your account is activated, you can file your tax return anytime before the 31st of January 2023.
If you’re not self-employed, register using form SA1. Once you've registered, you'll get your UTR within 10 days (or 21 if you're abroad). Create your online account using your UTR and sign up for Self Assessment online. You'll get an activation code sent to you in the post within 7 days of signing up (or 21 days if you're abroad). Once your account is activated, you can file your tax return anytime before the 31st of January 2023.
Though the deadline to file your taxes online is the 31st of January 2023 - this is also the deadline to pay your balancing paymentand your first payment on account. Your balancing payment covers any taxes you haven’t paid already throughout the year.
For this reason, we recommend that you file your taxes well ahead of the 31st of January to ensure you’re not left in the lurch with a large tax bill!
