Paying staff in Bitcoin, Ether or stablecoins can feel like a simple token transfer, but the payroll risk sits with the employer. If you skip PAYE because no pounds changed hands, HMRC may treat the payment as an underreported employment reward, leaving you exposed to unpaid tax, Class 1 NIC, interest and penalties.
Tax on salary paid in crypto: PAYE and NIC obligations in the UK remain unchanged where the tokens are readily convertible assets. You must value the crypto in GBP at payment, calculate and report PAYE and Class 1 NIC through an FPS, and pay HMRC. The practical steps are the RCA test, workable valuation evidence, payroll funding and records for any later CGT position for the employee.
Tax on salary paid in crypto: UK PAYE duties
Crypto wages normally remain taxable employment income.
Who pays HMRC when wages are tokens?
The employer pays HMRC through payroll, not the employee. An employee may later need to report Capital Gains Tax, but that later issue does not replace the employer’s PAYE, RTI or NIC obligations on payday.
For a typical RCA payment, payroll has four separate GBP figures: gross earnings, PAYE, employee Class 1 NIC and employer Class 1 NIC. The token amount is a fifth figure, calculated only after the GBP payroll position is known.
Minimum wage and pension duties remain
Crypto volatility does not waive National Minimum Wage compliance. The employment contract should state the GBP amount of salary, because a token price fall between agreement and transfer cannot leave the worker underpaid in GBP terms.
Check RCA status before crypto payroll
RCA status comes before any tax calculation.
A practical RCA decision tree
Crypto payment route on payday
1. Is it pay for employment?
2. Are trading arrangements present or likely?
Yes: normally RCA
Value in GBP, run PAYE and Class 1 NIC
No: do not self-certify
Take specialist advice on tax, NIC and reporting
Keep evidence of the market position and the decision on the payment date.
Non-RCA is not tax-free pay
A genuine non-RCA outcome may change the normal PAYE and Class 1 NIC route, but it does not make the earnings disappear. The employee can still face Income Tax exposure, and the employer may have separate reporting or NIC questions that need specialist review.
HM Revenue & Customs sets out its approach in the HMRC guidance and manuals. Record the analysis at each payment date, especially where a token’s trading position changes between months.
Set GBP pay, deductions and token delivery
A compliant token payroll starts with a GBP gross salary and a written valuation rule.
Worked example: monthly Bitcoin salary
Assume a London software firm pays an employee a fixed monthly gross salary of £4,000 on 30 April. Its approved policy uses the GBP mid-price from one named FCA-registered exchange at 14:00, which is £80,000 per Bitcoin, and the token is an RCA.
For illustration, using a standard 1257L tax code and 2026/27 monthly thresholds, PAYE is £590.50 and employee NIC is £236.16. Employer NIC is £537.45 where the employer has no Employment Allowance available, so the employer’s cost is £4,537.45 before exchange and network fees.

The practical recommendation is simple: fix the GBP gross pay first, preserve evidence for one repeatable payment-time price, and agree the deduction funding method in writing. A non-RCA conclusion, restricted tokens, directors’ awards or a token-only net promise need separate review before payment. That discipline makes the later audit trail much easier to build.
On these illustrative figures, the employee’s net pay is £3,173.34 (£4,000 less £590.50 PAYE and £236.16 employee Class 1 NIC). At the recorded Bitcoin price of £80,000, a net-token design would therefore transfer 0.03966675 BTC to the employee, before any separately agreed network-fee treatment. The employer must also reserve £1,364.11 in cash for HMRC: £590.50 PAYE, £236.16 employee NIC and £537.45 employer Class 1 NIC.
The payslip should show the GBP gross earnings and deductions, the valuation timestamp and source, the BTC quantity delivered, and whether the company or employee bears blockchain and exchange charges.
A robust GBP crypto valuation policy should name the exchange or independent index, the exact pricing convention (for example, executable bid, ask or mid-price), and the time at which the price is captured on each payday. It should also state how the business treats exchange spread, trading fees and network fees, because these can affect the token quantity transferred even where the GBP salary is fixed. For Bitcoin salary and stablecoin wages alike, retain a screenshot or API record showing the GBP pair, timestamp, quoted price, source and approver.
If the chosen source is unavailable, use a pre-approved fallback source and record why it was used, rather than selecting a favourable rate after the event.
Build an HMRC-ready crypto payroll audit trail
A crypto transfer without records is a payroll risk.
Controls to complete before payday
Before each crypto payroll UK payment, payroll should confirm that the employment contract or written employee consent permits the payment method and identifies the GBP salary, token, valuation rule and deduction funding method. Obtain and verify the receiving wallet address through a controlled process, screen the transaction and relevant counterparties under the firm’s proportionate AML and sanctions procedures, and require payroll and finance approval before release. After transfer, reconcile the blockchain transaction ID, token quantity, GBP valuation, payslip, bank funding and RTI reporting to the Full Payment Submission.
Reporting dates and retained records
Send the Full Payment Submission (FPS) to HMRC on or before payday. For most electronic payments, PAYE and NIC are due by the 22nd after the tax month ends on the 5th; postal payment is generally due by the 19th.
This guidance is not a substitute for advice on contractor payments, directors’ remuneration, token incentives, employment-related securities, overseas employees, salary sacrifice or arrangements involving illiquid, restricted or bespoke tokens. A purported non-RCA case should not be self-classified without professional review.
Keep the RCA analysis, approvals, wallet evidence, transaction records and payroll documents for at least three years from the end of the relevant tax year, while applying any longer retention period required by the business or other rules.
Questions & answers
Does an employer run PAYE on a Bitcoin salary?
Yes, where Bitcoin is an RCA, the employer normally values it in GBP and runs PAYE and Class 1 NIC through payroll. The FPS must be sent on or before the payday.
Can an employee be paid only in crypto?
A token-only arrangement can be possible, but the contract must state how PAYE and NIC are funded. It must also meet National Minimum Wage and pension duties in GBP.
Does selling crypto received as salary create Capital Gains Tax?
Yes, selling, swapping or spending received tokens can create Capital Gains Tax after the salary tax point. The employee’s acquisition cost is normally the GBP value already taxed as employment income.
The essentials:- Crypto pay usually remains GBP-valued employment income, with employer PAYE and Class 1 NIC duties where the token is an RCA.
- Decide and document RCA status before calculating tax or choosing a token quantity.
- Use a timed GBP valuation policy and a written method for funding deductions.
- Send the FPS by payday, pay HMRC by the relevant 19th or 22nd deadline, and retain the supporting payroll trail for at least three years.
Which crypto price should a UK employer use?
Use a documented, repeatable GBP price from a named exchange or index at a recorded payday time. Keep the timestamp, source, spread treatment and fallback method with payroll records.
