In April 2023, the UK Capital Gains Tax Allowance will be reduced from £12,300 to £6,000 for the 2023/24 tax year and then further reduced to £3,000 in 2024/25. This reduction will have a significant impact on all investors, especially those with cryptocurrencies. In this blog post, we explore how the reduction of the UK Capital Gains Tax Allowance will affect crypto investors and provide guidance on how to prepare for the change.


Overview of the UK Capital Gains Tax Allowance Reduction

Led by Prime Minister Rishi Sunak and Chancellor of the Exchequer Jeremy Hunt, the UK Government’s Autumn statement in November 2022 set out their plan to reduce debt servicing costs and leave more money to invest in public services. As part of the statement they said:

Going forward, the fairest way to restore the public finances is to ask everyone to contribute a little, with those on the highest incomes and those making the highest profits paying a larger share.

The government described the capital gains annual exempt amount, which has been frozen at the same level for several years as “generous” and announced a cut from £12,300 to £3,000 over the next two years. This reduction, combined with their plan to halve the dividend allowance is projected to raise a over £1.2billion a year from April 2025.

Hunt told the House of Commons:

Although my decisions today do lead to a substantial tax increase, we have not raised headline rates of taxation.

Impact of the Capital Gains Allowance Reduction on Crypto Users

Until now, this ‘generous’ capital gains allowance has shielded many UK individuals from having to declare a capital gains tax liability, so as the threshold decreases over the next two years we will see a massive increase in the number of UK tax payers filing a self-assessment tax return.

Most UK taxpayers are taxed via PAYE and suddenly a large proportion of these individuals will fall into the scope of taxation. Having never had to file a return before it will be really difficult for them to understand and comply with the tax laws. It’s likely to cause a big headache for many people and also put pressure on the accounting industry because there will be increased demand for professional help.

Crypto users are particularly vulnerable because the capital gains allowance reduction is likely to result in a significant increase in their tax liability but establishing this can be complicated. There is also much confusion around the taxation of crypto, the majority of users being oblivious that it is even taxable - in July 2022 HMRCs Uptake and Understanding Survey found that 58% crypto users were unaware they are liable to pay tax.

For those crypto investors who are aware, it is extremely hard to understand if they have a tax position to declare at all. Unfortunately, and as is commonly misunderstood it is not just a case of deciding ‘Did I cash out more than I put in?’ In fact, all crypto-to-crypto trades, purchases and gifts made with crypto are also counted as disposals by HMRC.

To figure out if they need to file, crypto investors need to work out their total capital gain by collating all crypto transactions, establishing the cost basis (original acquisition cost of each asset) and calculating the gain on each individual disposal, whilst also ensuring that the correct pooling rules are applied.

Crypto users previously able to guesstimate comfortably that their activity could not have generated a taxable gain above the £12,300 threshold without delving into the finer detail may suddenly find themselves having to go through the above process to comply, especially when the allowance reaches £3k.

Investors making lots of small crypto-to-crypto trades are at risk of being caught out because activity resulting in low value profit could soon accumulate and max out their allowance before crypto is even converted into pounds.

There should be careful consideration if profit from crypto is going to be used to pay the tax bill as this sale into fiat generates another taxable disposal. Because the UK's tax year ends in April, but tax is payable the following January, the timing of this disposal could affect the following tax year. There is also potential for assets to drop in value before "cashing out" leaving the individual with a high tax bill they are unable to pay.

How Crypto Investors can prepare for the reduction of the UK Capital Gains allowance

There is no point in dwelling, the allowance reduction is coming and so now is the time to get clued up and get ahead, especially while that £12,300 allowance still remains until 5th April 2023!

  1. Get to grips with the basics of crypto tax so that you can make more informed trading decisions, rather than just thinking about the tax consequences after. Check out HMRCs Cryptoasset Manual or our own Crypto Tax Guide if you prefer a lighter and more colourful read.
  2. Learn how to optimise your capital gains and make the most of your allowance. Are you sitting on any depleting assets that could be realised as a loss if sold, could you gift some assets to your spouse to make use of their capital gains allowance? Check out our blog - 5 things to do with your crypto before the end of the tax year for some ideas.
  3. Register for self assessment - if you’ve never filed a self assessment tax return then you’ll need to register with HMRC by 5th October to file the following January. For example, if you need to file your 2022/23 tax return, you should register by 5th October and you have until the 31st January 2024 to file and pay your taxes. 2023-01-DASHBOARD-LAUNCH-BLOG-HEADER
  4. Use a crypto tax calculator like Recap to do the complicated work for you. It calculates your taxes, providing a ready to file tax report and it also allows you to track your tax liability for the current year while it’s still possible to influence it. See if you’re within the allowance and get an estimate of the tax due to plan accordingly.
  5. Get professional help! Tax rules around crypto are complex, particularly if you’re making advanced trades or are involved DeFi, but that's no excuse for non-compliance. Consulting an accountant or tax professional with experience in cryptocurrency could save you a lot of headaches in the long run!
