Crypto nudge letters from HMRC – did you get one?
Whilst cryptocurrency may seem like a relatively new concept, since its inception back in 2009 it’s fast becoming one of the most popular forms of investment.
So if you’ve already taken the leap and invested, do you understand the tax implications? HMRC are quickly realising how much profit people are making, and therefore how much tax money there is to be had. In this blog we take a closer look at crypto, the nudge letters HMRC have been distributing, and what you should do if you receive one.
What are HMRC nudge letters?
Should HMRC have reason to believe you’ve made undisclosed profits on cryptocurrency and therefore owe tax, they may have sent you a nudge letter. In total 8,329 letters have been sent out, and HMRC have been collecting the data from crypto exchanges for the past 3 years.
If you currently own crypto and have previously sold any of your digital assets, you may not be aware that you owe Capital Gains Tax, or if HMRC consider you to be a ‘crypto trader’ then the amount of tax you’ll owe will be significantly more in the form of income tax on your holdings. If you generate interest from ‘staking’ your crypto, mine crypto, receive any amount of airdropped crypto, or trade large amounts on a regular basis, you may be subject to paying tax.
Since 2022 it’s predicted that 4.97 million people in the UK own some form of cryptocurrency, so it’s well worth HMRC’s time to start investigating further.
What do the letters say?
The letter will either indicate that you currently, or have previously held cryptoassets. The following three instances may indicate that a taxable gain has occurred:
- If you currently are / or have traded cryptocurrency in the past – i.e. you’ve sold your crypto assets for a higher value then you originally purchased it for
- If you swap your current form of cryptocurrency for another
- If you use your cryptocurrency to purchase something
These three points are all examples of crypto disposals. Point 1 is a traditional disposal, whereas points 2 and 3 are examples where HMRC want to increase awareness. It’s considered that cryptocurrency has been sold at the point at which a transaction has taken place, and therefore either more cryptocurrency has been accrued, or something has been purchased by the owner. The Capital Gains Tax rule would apply to both scenarios.
How much tax is therefore due?
Receiving a nudge letter won’t mean you automatically owe tax, but it is worth considering if you need to report your gains and losses to HMRC. The Capital Gains annual exemption for the current tax year (2023/24) is £6,000, which will be reduced to £3,000 for the 2024/25 tax year. Should your net gain exceed this amount, you’ll need to report this to HMRC via your self-assessment tax return. If your proceeds exceed £50,000 and your gains are still below the annual exemption amount, you’ll still need to report it to HMRC.

What’s the next step?
It’s predicted that the next step will be HMRC sending out enquiry letters, which will request greater detail from yourself regarding your cryptocurrency holdings. Whilst it might be tempting to withhold this information, with HMRC’s access to data becoming greater and greater, it’ll become harder to hide from them.
Tax evasion is treated extremely seriously by HMRC, and anyone claiming to not understand their tax responsibilities on their crypto moving forward can expect the usual heavy fines and unpaid tax bills.
