Cryptocurrency Taxation in the UK

Cryptocurrency Taxation in the UK

What Individuals and Businesses Need to Know

Cryptocurrency has moved from a niche investment to a mainstream financial asset. Whether you are trading Bitcoin, investing in Ethereum, or using digital assets for business transactions, it’s important to understand how HMRC taxes cryptocurrency.

Many taxpayers mistakenly believe crypto is anonymous or untaxed.

In reality, HMRC has clear rules — and increasing access to crypto transaction data.

Is Cryptocurrency Taxable in the UK?

Yes. HMRC treats cryptocurrency as an asset, not as money. This means that most crypto transactions are taxable events.

HMRC guidance applies to:

• Individuals
• Sole traders
• Limited companies
• Investors and traders

Failing to declare crypto activity can lead to penalties, interest, and investigations.

When Do You Pay Tax on Cryptocurrency? You may need to pay tax if you:

• Sell cryptocurrency for fiat currency (GBP)
• Exchange one cryptocurrency for another
• Use crypto to pay for goods or services
• Gift cryptocurrency (with some exceptions)
• Receive crypto as income (e.g. mining, staking, or payment)

Each of these actions can trigger a Capital Gains Tax (CGT) or Income Tax liability.

Capital Gains Tax on Crypto Investments

Most individuals will pay Capital Gains Tax on profits made from cryptocurrency.
How CGT Works:

• You calculate the gain: sale value minus purchase cost
• You can deduct allowable costs (transaction fees, platform fees)
• Each individual has an annual CGT allowance
• Gains above the allowance are taxed at the relevant CGT rate

Losses can be carried forward and offset against future gains.

Income Tax on Cryptocurrency

Some crypto activities are treated as income, not capital gains.
Income Tax may apply if you receive crypto from:

• Mining
• Staking
• Airdrops
• Salary or freelance payments
• Business trading activity

In these cases, crypto is taxed at its GBP value on the date received and must be declared on a tax return.

Cryptocurrency for Businesses and Companies
If a business accepts or trades cryptocurrency:

• Crypto receipts are treated as business income
• Gains may be subject to Corporation Tax
• Accurate bookkeeping in GBP is required
• VAT treatment depends on the transaction type

Crypto accounting for companies is complex and often misunderstood, making professional advice essential.

Record Keeping for Crypto Transactions
HMRC requires detailed records, including:

• Dates of transactions
• Value in GBP
• Type of cryptocurrency
• Wallet addresses
• Exchange statements
• Transaction and gas fees

Records must be kept for at least 5 years after the submission deadline.
