As digital assets continue to gain mainstream traction, understanding cryptocurrency tax obligations has become essential for both individuals and businesses operating in the UK. The HM Revenue & Customs (HMRC) treats crypto assets not as currency, but as property subject to taxation depending on their use and nature.
This guide breaks down how crypto tax applies across different scenarios—covering capital gains, income, inheritance, and corporate responsibilities—while helping you stay compliant with current UK regulations.
What Are Cryptocurrencies Under UK Tax Law?
According to HMRC, cryptographic assets—commonly referred to as tokens or cryptocurrencies—are digital representations of value secured by cryptography. These can be:
- Transferred
- Stored
- Electronically traded
While all crypto assets rely on distributed ledger technology (DLT), not every DLT application involves a cryptocurrency.
HMRC identifies four main types of crypto assets:
- Exchange tokens (e.g., Bitcoin): Used primarily as a means of payment or investment.
- Utility tokens: Grant access to a service or product within a specific platform.
- Security tokens: Represent financial interests such as ownership, profit-sharing, or repayment rights.
- Stablecoins: Designed to minimize volatility by being pegged to stable assets like fiat currencies or precious metals.

It's important to note that tax treatment depends on the function and usage of the token—not its label. HMRC does not classify crypto as money, but rather as an asset subject to various tax rules.
Personal Taxation of Cryptocurrency
Most individuals hold crypto as an investment. Profits from disposal are typically subject to Capital Gains Tax (CGT), while losses may offset other gains.
However, under certain circumstances, HMRC may consider activity to constitute trading—triggering Income Tax liability instead.
Capital Gains Tax (CGT) on Crypto
If you're holding crypto for personal investment, any profit from selling or exchanging it counts as a capital gain.
Key points:
- Each type of cryptocurrency must be tracked in a separate "pool" due to HMRC’s pooling rules.
- Disposal includes converting crypto to fiat, swapping one crypto for another, or using it to buy goods/services.
- The cost basis includes the original purchase price plus transaction fees.
- If the crypto was received via mining or staking and already taxed as income, that amount becomes part of the asset’s base cost.
Annual CGT allowance (£6,000 in 2023/24, reducing to £3,000 in 2024/25) applies. Gains above this threshold are taxed at either 10% (basic rate) or 20% (higher rate), depending on total income.
When Is Crypto Taxed as Income?
HMRC may treat profits as trading income if your activities show signs of running a business. Factors considered include:
- Frequency and volume of trades
- Level of organization and sophistication
- Intent to profit from short-term price movements
- Source of finance and time devoted
There is no fixed number of trades that triggers this classification—it’s a facts-and-circumstances test. Most casual investors won’t meet the threshold, but active traders might.
Additionally:
- Mining and staking rewards are taxed as miscellaneous income or trading profits, depending on scale and effort involved.
- Contrary to outdated myths, crypto gains are not treated as gambling winnings—they are fully taxable.
Foreign Currency Considerations
All tax reporting must be in British pounds (GBP). Even if the value of your crypto remains unchanged in USD or BTC terms, exchange rate fluctuations between purchase and disposal can create taxable gains or losses.
For example: converting ETH → BTC → GBP requires two conversions, adding complexity to calculations.

Employment and Benefits-in-Kind
Receiving salary or bonuses in crypto is increasingly common—especially in tech and blockchain firms.
Such payments are subject to:
- PAYE (Pay As You Earn): If the token is easily convertible into cash (e.g., listed on major exchanges).
- Benefits-in-kind tax: If not readily exchangeable.
- National Insurance Contributions (NICs) apply accordingly.
The taxable value is based on the GBP market value at the time of receipt.
Inheritance Tax (IHT) Implications
Crypto assets form part of your estate and may be liable for Inheritance Tax if they exceed the nil-rate band (£325,000).
A key issue is determining location (situs) of digital assets for non-UK domiciled individuals. HMRC currently considers crypto held by UK residents to be located in the UK—making it potentially subject to IHT regardless of server location or wallet type.
Secure record-keeping and access planning are crucial for executors.
Record Keeping Requirements
Exchanges often retain records only for limited periods. It’s the taxpayer’s responsibility to maintain detailed logs of:
- Dates of transactions
- Type of transaction (buy, sell, swap, gift)
- Amounts in crypto and GBP value at time of transaction
- Wallet addresses
- Purpose of transaction
Failure to keep proper records can lead to penalties during an HMRC inquiry.
Corporate Taxation of Cryptocurrency
Businesses engaging in crypto-related activities must comply with several tax frameworks.
Trading Profits and Corporation Tax
If a company actively trades crypto, profits fall under trading income, taxed at standard Corporation Tax (CT) rates (currently 25% for profits over £250,000).
Factors indicating trading status:
- Regularity and scale of operations
- Business planning and marketing
- Risk-taking behavior
Intangible Fixed Assets
Crypto held long-term may qualify as an intangible fixed asset if:
- It's recorded as such in accounts
- Acquired for ongoing business use
This allows for potential amortization relief under CT rules.
Chargeable Gains for Companies
Even non-trading companies pay CT on capital gains from disposing of exchange tokens. Losses can offset gains but come with restrictions when transferring tokens to connected parties.
VAT Treatment
HMRC confirms:
- Supplying goods/services for crypto is subject to VAT in the normal way.
- Mining rewards are outside the scope of VAT.
- Exchanging one crypto for another does not trigger VAT.
Stamp Taxes
While crypto itself isn’t a "securities" for Stamp Duty purposes, HMRC reviews transfers case by case. If crypto is used to buy:
- Shares: May trigger Stamp Duty Reserve Tax (SDRT)
- Land/property: Could attract Stamp Duty Land Tax (SDLT)
Frequently Asked Questions (FAQ)
Q: Do I pay tax if I just hold crypto?
A: No. Holding crypto without disposal doesn’t trigger tax. Tax arises only when you sell, swap, spend, or gift it.
Q: Are NFTs taxed like other cryptocurrencies?
A: Yes. HMRC treats most NFTs similarly to exchange tokens unless they represent specific rights (e.g., royalties), which could affect classification.
Q: What happens if I lose access to my wallet?
A: You may claim a capital loss if you can prove permanent loss or destruction. Documentation is critical.
Q: Can I avoid CGT by moving abroad?
A: Possibly—but only if you become non-resident before disposing of assets. UK residents are taxed on worldwide gains.
Q: Is gifting crypto taxable?
A: Yes. Gifting counts as disposal. CGT applies based on market value unless gifted to a spouse/civil partner.
Q: How far back can HMRC investigate?
A: Up to 20 years in cases of deliberate non-compliance; six years for careless errors; four years for innocent mistakes.
