The Definitive Guide to UK Crypto Taxes (2022)

Reporting cryptocurrency on your taxes is stressful in any country — the UK is no exception.

As cryptocurrencies like Bitcoin have grown in popularity over the years, so has the number of people who are making money by investing or trading them.

We know that trying to understand the tax code can feel overwhelming — so we wrote this guide to help UK crypto investors like you better understand HM Revenue and Customs (HMRC’s) guidance on cryptocurrency taxes.

Crypto Tax Basics

What is cryptocurrency?

If you’re reading this guide, it’s likely that you’ve already dabbled with cryptocurrencies. We won’t do a deep dive on the fundamentals of crypto within this piece, but we will explain how the UK government views assets like Bitcoin and Ethereum.

In their policy paper, HMRC explains that crypto-assets (or ‘cryptocurrency’) are cryptographically secured digital representations of value or contractual rights that can be:

  • transferred
  • stored
  • traded electronically

HMRC does not consider cryptocurrency to be currency or money. Under UK crypto tax rules, profits on cryptocurrency disposals are considered capital gains and are accordingly subject to capital gains taxes.

How is cryptocurrency taxed in the UK?

In the United Kingdom, cryptocurrency is subject to capital gains and income tax.

Capital gains tax events in the UK

When you dispose of cryptocurrency, you’ll incur a capital gain or loss depending on how the price of your crypto has changed since you originally received it. HMRC explains that disposals include:

  • Selling cryptocurrency for fiat

  • Trading cryptocurrency for other cryptocurrencies

  • Using cryptocurrencies to purchase goods and services

“Many taxpayers are unaware that crypto-to-crypto transactions are taxable. Remember, these transactions should be carefully reported for tax reporting purposes.”
quote
Richard Baldwyn

Income tax

Typically, you’ll recognize income when you earn cryptocurrencies. The following transactions are subject to income tax.

  • Receiving cryptocurrency as compensation for labour
  • Mining cryptocurrency as a hobby
  • Staking cryptocurrency

How much is cryptocurrency taxed in the UK?

During the 2021-2022 tax year, UK taxpayers get a Capital Gains tax-free allowance of £12,300. Capital gain income above this allowance is subject to the following tax rates.

uk-guide

For example, if you earned £50,000 of income and had £13,000 of cryptocurrency capital gain, you’d pay 10% tax on £700 of capital gain.

Can the HMRC track my cryptocurrency?

In recent years, the HMRC has taken steps to curb crypto tax evasion. The HMRC has requested and obtained customer data from major exchanges and sent ‘nudge’ letters to crypto investors to encourage them to pay capital gains and income tax.

What happens if I don’t report my crypto gains and losses?

Under HMRC rules, taxpayers who do not disclose gains could face a 20% capital gains tax plus any interest and penalties of up to 200% of any taxes due. Those found to have evaded the tax could also face criminal charges and jail time.

There’s no guarantee of what will or will not happen if you fail to file your cryptocurrency taxes with HMRC. However, it’s recommended to stay compliant by properly filing all of your capital gains and income.

If you haven’t been reporting your gains or losses in previous years, you can get everything in order by filing an amended self-assessment tax return.

How to legally reduce your crypto taxes?

While there’s no way to legally avoid your crypto taxes, there are strategies that you can use to reduce them.

1. Optimise for tax-free thresholds

Remember, your first £12,300 of capital gain is tax-free. It can be valuable to keep this number in mind when disposing of your cryptocurrency.

2. Dispose of your cryptocurrency in a low-income year

Your tax rate is determined by how much income you receive in a given year. As a result, disposing of your crypto in a low-income year can lead to a significantly reduced tax rate.

3. Donate your cryptocurrency

If you donate your crypto to a registered charity without receiving anything in return, you can deduct the full fair market value of your crypto. However, if the price of your cryptocurrency has increased since you originally received it, you will incur a capital gain upon your donation.

What is the deadline for reporting my crypto taxes?

In the UK, the tax year starts on April 6th and ends on April 5th of the following year.

The deadline for submitting your tax return is different for paper and online submissions. For the 2021-2022 tax year, the paper deadline is October 31st, 2021 and the online deadline is January 31st, 2022.

How to calculate your crypto taxes

chapter-panelchapter-panel

How can I calculate my cryptocurrency capital gains?

The formula we use to calculate these capital gains and losses is as follows:

Fair Market Value - Cost Basis = Gain/Loss

Fair Market Value is the market price of the cryptocurrency at the time you sold, traded, or disposed of it. Cost Basis refers to the amount it costs you to acquire the coin.

How are transaction fees and gas fees taxed?

Any fees involved in acquiring or disposing of your crypto can be added to your cost basis. This includes any transaction fees and gas fees.

uk-guide

Reporting fees does have benefits for crypto investors. In the event that you sell your crypto at a profit, a higher cost basis can reduce your capital gains tax.

How do I determine my cost basis?

Calculating capital gains and losses from your crypto transactions becomes more complex when you have multiple transactions to account for. The UK requires a specific type of method for calculating the cost basis of your coins known as Shared Pool Accounting.

With the shared pooled accounting method, you are essentially taking an average of the costs you have incurred to acquire your crypto. These averages can be used to calculate your cost basis per coin. Each cryptocurrency has its own shared pool for determining basis.

Example:

Let’s take an example of a crypto investor who buys Ethereum at multiple price points in a given year.

uk-guide

In this example, Emma has a total pool of 2.5 ETH prior to her October sale. To calculate her cost basis on a per ETH basis, we need to average out her total costs.

Her allowable costs for her total pool of 2.5 ETH are £4,000 (May buy of £1,500 plus August buy of £2,500). We then simply divide her total allowable costs by her total pool of ETH.

£4,000 / 2.5 ETH = £1,600/ETH

As you can see, Emma’s cost basis per ETH in her shared pool is £1,600.

We can use the equation from above to calculate Emma’s capital gain from the sale of her 1 ETH in October.

Fair Market Value - Cost Basis = Gain/Loss
£3,000 - £1,600 = £1,400 Gain

Emma recognizes a £1,400 capital gain from selling her 1 ETH in December.

Can I report my crypto capital losses?

uk-guide

In the United Kingdom, capital losses can be used to offset your capital gains for the year. If you have a net loss for the year, it can be carried forward into future tax years.

As a result, claiming capital losses can significantly reduce your tax liability, and even bring your total taxable gains below the tax-free allowance amount of £12,300.

However, it’s important to remember that the Same Day Rule and the Bed & Breakfast Rule prevent investors from claiming losses solely for tax purposes.

What is the Same Day Rule and the Bed & Breakfast Rule?

There are two additional rules that apply to crypto disposals in the UK: the Same Day Rule and the Bed & Breakfast Rule.

Each of these rules are designed to prevent wash sales, which is a scenario in which an investor intentionally sells or disposes of an asset that has decreased in value and then buys it back soon after. The Same Day Rule and the Bed & Breakfasting Rule exist to eliminate the potential tax benefits of wash sales.

The Same Day Rule explained

If you buy and sell a cryptocurrency the same day, then the sale is considered made from the coins you bought on that same day.

That means the cost basis for your sale will be the acquisition cost of the crypto you bought on the same day. This will be the case even if the acquisition of the crypto takes place after the sale — as long as they are both on the same day.

The Bed & Breakfast Rule explained

Also known as the 30-day Rule, this rule states that any of the crypto you acquire within 30 days of a sale will be used as its cost basis.

Each of these rules impacts which cryptos you “sell” and the order you sell them in from an accounting perspective.

When calculating your gains and losses and applying these three rules, your cryptocurrency will be treated as being disposed of in the following order:

  • Same Day Rule: Coins acquired on the same day as the disposalt. If you are selling more than you bought, move on to the next rule.
  • Bed and Breakfasting Rule: Coins acquired in the 30 days following the day of disposal. If you are selling more than you bought, move on to the next rule.
  • Crypto-pool accounting: All previous coins purchased, price averaged.

Claiming losses on worthless assets/lost keys

If you hold cryptocurrency that’s become worthless or lost access to your private keys, you can claim a capital loss. A capital loss can offset any capital gains for the year and reduce your overall tax liability.

Claiming losses on worthless crypto-assets

uk-guide

If you hold a crypto-asset that becomes worthless, you can file a negligible value claim. This allows you to treat the asset as if you’ve disposed of it, even if you still hold it. You’ll also be able to claim the associated capital loss.

Your negligible value claim should include the following information.

  • The type of crypto-asset
  • The amount at which the asset should be treated as disposed of (typically £0)
  • The date the ‘disposal’ should take place

Claiming losses on lost keys

A negligible value claim can also be filed in the case that you lose your private keys. This claim should be filed in the same year that you lost access to your cryptocurrency.

Taxes on Crypto Income - Mining and Staking

Cryptocurrency received from mining, staking, interest, or wages is considered a form of income. The income you recognize is equal to the fair market value of the crypto at the time you gain possession of the coin.

The amount of income recognized then becomes the cost basis in the coin moving forward.

Example:

Here’s an example that highlights how cryptocurrency earned from staking rewards is taxed.

uk-guide

Of course, it’s also important to remember that your cryptocurrency income from mining and/or staking is classified differently whether you are mining as a hobby or as a business.

Mining as a Hobby

If you are mining as a Hobby, your income has to be declared separately under the heading of "Miscellaneous Income" on your tax return. Appropriate expenses can be deducted from taxable income.

Remember, the HRMC has stated that there is no need to complete a Self Assessment tax return for your mining activity if you’ve received less than £1,000 in crypto-assets.

Mining as a Business

If you are mining as a business, your mining income will be added to trading profits and be subject to income tax. Appropriate expenses are also deductible.

You can learn if your activity should be classified as a business or as a hobby with HMRC’s guide here.

What if I’ve earned cryptocurrency from my job?

If you earned crypto income in compensation for your work, you will be taxed based on your cryptocurrency’s fair market value at the time it was received.

How are airdrops taxed?

uk-guide

According to the HMRC, cryptocurrency received from airdrops may be considered income if it’s given in exchange for a product or service.

Cryptocurrency from airdrops is not considered income if it meets the following two conditions:

  • It’s not part of a trade or business that involves cryptocurrency exchange tokens or mining
  • Nothing was done in exchange for the airdropped cryptocurrency

To better understand how airdrops are taxed, consider the 2021 $ENS airdrop. In this case, anyone who previously used the Ethereum Naming Service was entitled to claim $ENS tokens. It’s likely that this would be considered a taxable event since the tokens were given in exchange for using a service.

Whether or not your airdrop rewards are considered income, disposing of your airdropped cryptocurrency is considered a taxable event subject to capital gains tax.

How are crypto gifts taxed?

Giving a crypto gift to your partner or spouse is considered tax-free. In addition, this will not be counted towards your capital gains allowance for the year.

uk-guide

On the other hand, giving a crypto gift to someone other than your spouse or partner is considered a disposal event. You will need to keep a record of the fair market value of your cryptocurrency at the time the gift was given to calculate your capital gains or losses.

How are crypto donations taxed?

uk-guide

If you choose to donate cryptocurrency to charity, you are entitled to Income Tax relief. If you are a higher-rate taxpayer, you’ll be able to claim the difference between your rate and the basic tax rate based on the fair market value of your crypto at the time it was donated.

However, you may be required to pay capital gains in the following circumstances:

  • The fair market value of the cryptocurrency is higher than it was when you received it
  • In the case of a tainted donation (when a taxpayer makes an arrangement with a charity to obtain a financial advantage)

How are NFTs taxed?

While the HMRC has not released specific guidance pertaining to NFTs, tax experts believe that they will likely be taxed similarly to physical artworks and collectables.

If you are minting an NFT, it’s likely that any earnings from primary and secondary sales will be considered income and will be taxed accordingly.

uk-guide

If you are buying an NFT with cryptocurrency, it is likely that you will incur capital gains or losses depending on how the price of the cryptocurrency you are using to make the purchase has fluctuated since you originally received it.

uk-guide

If you are selling an NFT, it is likely that you will incur capital gains or losses depending on how the price of your NFT has fluctuated since you originally received it.

uk-guide
“Many investors have trouble reporting their NFT taxes for one simple reason: they aren’t taking the time to record information such as the cost basis of their NFT or its fair market value at the time it was sold.”
quote

How is DeFi taxed?

According to the HRMC, DeFi transactions can be subject to capital gain or income tax depending on the specific nature of the transaction.

How are DeFi staking rewards taxed?

In some situations, staking an asset can be considered a taxable crypto-to-crypto swap. For example, when you deposit ETH fand receive stETH, you will incur a capital gain or loss depending on how the price of your crypto has changed since you originally received it.

In addition, any rewards you receive from staking will be considered income subject to income tax.

How are DeFi loans taxed?

Currently, many DeFi protocols offer loans to users. When a user locks up their existing cryptocurrency as collateral, they can receive tokens in return. For example, you could put ETH as collateral and in exchange, receive DAI.

Giving collateral to a DeFi protocol is a taxable event. You will incur capital gains based on how the price of your collateral has changed since you originally received it.

How to report your crypto taxes?

Why can’t my crypto exchanges give me capital gains and losses forms?

Due to the transferable nature of cryptocurrencies, exchanges don’t typically know the cost basis of your assets. This prevents them from being able to give you complete gains and losses reports.

To illustrate this further, let’s look at an example.

Example:

uk-guide

In this example, Coinsmart has no way of knowing Mark’s cost basis of his 1 BTC. Coinsmart only can see Mark trading his Bitcoin for Ethereum. They have no idea when, for how much, or where that BTC was originally acquired.

Because of this, Coinsmart can’t possibly tell Mark what the capital gain or loss was on his BTC trade for ETH. It’s missing an essential piece of the equation: cost basis.

Remember, cost basis is needed to calculate your capital gains or losses on crypto disposals.

This example demonstrates this problem at a small scale. Transfers happen all of the time, and it’s the transferability of crypto that makes it difficult for cryptocurrency exchanges to report capital gains and losses on your behalf. The reporting burden falls to you as the taxpayer.

To summarise, the second you transfer crypto into or off of your cryptocurrency exchange, the exchange loses the ability to report on your gains and losses. Coinbase explains this themselves to their users within their company tax guide:

uk-guide

How can I track my crypto transactions?

As you can see, capital gains and losses calculations can quickly become tedious when there are a significant number of transactions to account for.

In addition, many cryptocurrency traders have been trading for long periods of time without keeping records of their trades. To properly calculate your capital gains and losses, you need to have records of the price in GBP for every crypto asset you traded or sold at the time of the sale.

This challenge is the reason why many cryptocurrency traders are turning to cryptocurrency tax software to automate the entire capital gains and losses reporting process.

How to report cryptocurrency on your taxes

To report your crypto transactions and pay your capital gains tax, you can use the HMRC’s Government Gateway online service. Here, you’ll be able to fill out a Self Assessment Tax Return and a Capital Gains Tax Summary.

Keep in mind, the HMRC requires you to keep records of all of your cryptocurrency transactions for at least a year after the Self Assessment deadline.
