UK businesses that hold, trade, or accept cryptocurrency face corporation tax, VAT, and payroll considerations. Unlike individuals, whose cryptocurrency is generally taxed through Capital Gains Tax and the annual exempt amount, a company must think about the distinction between capital gains and trading income from the outset — because it changes which rate applies and how losses can be relieved. This guide walks through the main tax obligations a UK business must prepare for when it touches crypto.
When a Business Is Taxed
| Activity | Tax Treatment |
|---|---|
| Buying crypto as an investment | Corporation Tax on gains |
| Accepting crypto as payment | Trading income |
| Mining crypto as a business | Trading income |
| Paying employees in crypto | PAYE / NIC |
| Trading crypto as a business | Trading income |
Corporation Tax on Crypto
| Asset Type | Treatment |
|---|---|
| Crypto held as investment | Chargeable gain (corporation tax) |
| Crypto held as trading stock | Trading income |
| Crypto received as payment | Trading income at receipt value |
The rate is 19-25% depending on profit level.
The 19-25% headline rate reflects the UK’s main rate of corporation tax, which applies on a sliding scale depending on how much annual profit the company makes. For a business holding crypto purely as an investment, gains on disposal are chargeable gains subject to corporation tax rather than personal CGT. That is an important difference from individuals, who enjoy an annual exempt amount; companies receive no such allowance, so even a small gain can still be within the charge to corporation tax.
Accepting Crypto as Payment
| Step | Tax Treatment |
|---|---|
| 1 | Receive crypto as payment for goods/services |
| 2 | Value at market rate when received |
| 3 | Record as trading income |
| 4 | When crypto is sold, any gain/loss is also trading income |
You’re taxed on the value of crypto when received. Any subsequent gain or loss is also trading income.
This matters because it means there is no capital gains treatment for crypto received in the course of trade — every element, from the initial receipt to any later disposal, runs through the trading profit computation. If you accept Bitcoin for a service, you must recognise the market value in sterling at the point of receipt as turnover. When you later convert that Bitcoin into pounds (or another asset), the difference between the disposal proceeds and the value at which it was brought into account is itself a trading profit or loss.
VAT on Crypto Transactions
| Transaction | VAT Treatment |
|---|---|
| Selling goods for crypto | VAT due on the GBP value at sale |
| Selling crypto for GBP | VAT exempt (financial service) |
| Crypto-to-crypto trades | VAT exempt |
| Mining rewards (business) | VAT applies to fees received |
Paying Employees in Crypto
| Requirement | Details |
|---|---|
| PAYE applies | Crypto is a “readily convertible asset” |
| NIC applies | Both employer and employee NI |
| Market value | Use the crypto value at the time of payment |
| RTI reporting | Report on or before payment date |
| HMRC approval | Not needed but must follow rules |
Accounting for Crypto
| Method | How It Works |
|---|---|
| Fair value accounting | Crypto valued at market rate on balance sheet |
| Realised gains/losses | Taxed when disposed |
| Functional currency | Report in GBP |
Record Keeping for Businesses
| Record | Why |
|---|---|
| Transaction date and value | Tax point for VAT/corporation tax |
| Customer details | For VAT invoices if applicable |
| Wallet addresses | Audit trail |
| Valuation method | Consistent approach |
| Exchange rates | Source of GBP conversion |
Record-keeping is where many businesses trip up, because crypto transactions can span exchanges, wallets, and years of activity. HMRC expects you to be able to reconstruct the full history of each coin or token, including the source of the sterling conversion you used. The golden rule is to settle on one valuation method and exchange rate source at the outset, record every transaction at the moment it happens, and keep the wallet addresses alongside so the trail can be traced if your tax return is questioned.
Bottom Line
UK businesses are taxed on crypto through corporation tax (gains) or trading income (regular activity). VAT applies when selling goods for crypto but not on crypto-to-crypto trades. Paying staff in crypto triggers PAYE and NIC. Keep detailed records of every transaction. Tax treatment depends on whether crypto is held as an investment or as trading stock — this distinction is crucial.
The distinction between holding crypto as an investment and holding it as trading stock is the single most consequential decision in business crypto tax. It determines whether profits are taxed as chargeable gains or trading income, how the 19-25% corporation tax rate applies, and how losses can be carried forward and relieved. For a company that accepts or trades crypto in the ordinary course of its business, the trading route is almost always the correct treatment, which means every receipt and disposal must be tracked through the accounts at market value in sterling. Where uncertainty remains, especially around whether an activity amounts to trading or investment, professional advice is well worth the cost given what is at stake.
