Tue Sep 27 2022
If you're a crypto enthusiast in the UK and the 2022/23 tax year has you considering filing a tax return for the first time, you're in the right place! Before you’re able to file your taxes you must register for Self Assessment with HMRC by the 5th of October.
In this article, we'll explain who needs to file a tax return, who needs to register for Self Assessment and provide you with a step-by-step guide on how to do so.
Who needs to file a tax return?
Before diving into the registration process, let's first establish whether you need to file a tax return for the 2022/23 tax year. The 22/23 tax year covered the period from 6th April 2022 to 5th April 2023. You must send a tax return if any of the following criteria apply to you (note - we’re covering things outside of crypto here too):
- You were self-employed as a 'sole trader' and earned more than £1,000 (before tax relief).
- You were a partner in a business partnership.
- Your total taxable income exceeded £100,000.
- You had to pay the High Income Child Benefit Charge.
- You received untaxed income from sources like renting out a property, tips, commission, savings, investments, dividends, or foreign income.
As a crypto investor, it’s likely that final bullet applies to you. It's essential to file a tax return if your capital gains exceeded the annual allowance, which was £12,300 for the 2022/23 tax year, or if your disposal proceeds exceeded four times the allowance. If you received more than £1,000 Miscellaneous income from crypto during the 2022/23 tax year then this also needs to be reported and paid.
