You can pay salary or bonuses in Bitcoin, but you must still run UK payroll in pounds. Before payday, set a reliable GBP value for the Bitcoin. Calculate Income Tax and National Insurance contributions (NIC), submit RTI, and ensure HMRC receives sterling amounts.
Bitcoin payroll & PAYE: rules before payday
HM Revenue & Customs (HMRC) normally looks at what a worker receives for their job. It does not focus only on the payment label. Bitcoin paid as wages is usually employment income. Bitcoin that can be readily sold on an exchange will commonly meet the RCA test.
Put the pay terms in writing
For Bitcoin salary, written pay terms should state gross pay in GBP and the normal pay date. They should say whether Bitcoin is a contractual settlement method or a discretionary arrangement. They should also name the pricing source for converting net pay.
The employee should clearly agree to the wallet-payment process. The agreement should cover what happens if the address is wrong or the transfer is delayed. UK payroll also needs a separate National Minimum Wage check.
An employer should not assume that a volatile cryptoasset transfer counts as cash wages for minimum-wage purposes.
Keep the GBP wage entitlement, tax deductions and Bitcoin transfer evidence together.
Run a Bitcoin pay run and fund deductions
The lowest-risk route sets gross pay in GBP, calculates deductions normally, then sends Bitcoin equal to the net GBP value. Send the Full Payment Submission (FPS) to HMRC on or before payday. This applies even where the worker's wallet receives no pounds.
A worked GBP-to-BTC example
Assume monthly gross pay is £5,000. Assume the approved Bitcoin price is £50,000 per BTC at the relevant payment point. If payroll calculates £900 PAYE and £300 employee NIC, net pay is £3,800.
The wallet transfer is 0.07600000 BTC (£3,800 ÷ £50,000). Apply the documented rounding rule. The FPS and payslip show £5,000 gross pay, £900 PAYE and £300 employee NIC.
Those records must be in GBP. Calculate and fund employer NIC separately in GBP.
Choose how tax will be funded
If the worker wants the full £5,000 value in Bitcoin, the employer still owes PAYE and NIC in pounds. The business can ask for cash before payroll, send only net Bitcoin, or gross up the pay.
The most frequent error here is sending the full Bitcoin amount without settling tax deductions.
A £5,000 Bitcoin payment is not the same as £5,000 gross salary settled in Bitcoin. In a net settlement, Bitcoin equals gross GBP pay less PAYE and employee NIC. The BTC amount depends on the documented GBP price, tax calculation and rounding method. Sending the full £5,000 value without recovery may create extra taxable pay or employee debt.

The same figures illustrate the reconciliation payroll needs. Assume monthly gross pay is £5,000 and Bitcoin is £50,000 per BTC. Assume payroll calculates £900 PAYE tax and £300 employee NIC.
Net pay in Bitcoin is £3,800 ÷ £50,000 = 0.07600000 BTC. The payslip and RTI show £5,000 gross pay and £1,200 deductions in GBP. They do not report 0.1 BTC as gross pay.
If employer NIC is £625, total cash-and-crypto cost is £5,625. This excludes pension and provider charges. The business should state how it rounds BTC to eight decimal places.
It should also state how it settles residual GBP pence.
A GBP-led payroll is the safest practical approach for Bitcoin wages. It keeps PAYE, NIC and RTI in the currency HMRC expects. Bitcoin can then settle net pay, but only after agreed pricing and deductions. This approach does not remove separate minimum-wage, contract, pension, or employment-related securities issues.
Choose the right crypto pay structure
Bitcoin paid as contractual wages is usually simpler when the employee agrees a GBP salary. The employee then receives the net GBP value in Bitcoin. Changing the token, payer or reimbursement method can change the compliance work.
| Scenario | Likely route | Main risk | Employer action |
|---|
| Bitcoin contractual wages | RCA, PAYE and NIC through payroll | No cash for deductions | Settle net BTC or collect cash first |
| Token not readily tradeable | Fact-specific, may not be RCA | Wrong PAYE timing | Obtain tailored advice |
| Bitcoin bonus | Usually employment income | Calling it a benefit | Run it through payroll |
| Third party sends Bitcoin | May still be employment income | Missing employer reporting | Review who arranged payment |
| Tax not reimbursed | Possible extra taxable value | Employer-funded liability | Document recovery or gross-up |
Keep a valuation evidence trail
Use one approved market-price source. Record the exact timestamp and capture the GBP price. State the rounding rule and keep the transaction hash and payslip.
A consistent method is easier to defend than choosing the best exchange price after payment.
Separate salary tax from later CGT
Employment income on payday does not make later gains tax-free. The Bitcoin value received after employee deductions will usually form the employee's acquisition cost. A later sale, token exchange, or spending transaction can create a Capital Gains Tax calculation.
If 0.07462340 BTC is later sold for more pounds, CGT may apply. CGT may also apply if it is swapped for another token. Spending it on goods can also trigger a calculation.
Bitcoin is commonly a readily convertible asset (RCA) when it can be readily exchanged for money. PAYE and NIC then generally run through UK payroll. A token with no practical market may need a different analysis.
The tax point for such a token should not be assumed to match that of a normal Bitcoin transfer. A third-party transfer cannot be ignored because the employer's wallet did not send it. Employer reporting duties may still arise where employment caused or arranged the payment.
Record who promised, funded and transferred the payment. Record the GBP value at the relevant payment point.
Prevent reporting and record-keeping errors
Send the FPS on or before payday. Pay HMRC by the 22nd of the following tax month for electronic payments. Pay by the 19th for non-electronic payments.
Bitcoin does not extend those PAYE deadlines.
Check the payroll file before release
Your pre-payment check should cover the signed contract change and worker status. It should cover the gross GBP amount, tax code and pension deductions. Check the price source, wallet address, approval, payment evidence and FPS data.
A common case involves a correct Bitcoin transfer but an FPS sent late. The wallet record does not cure the late RTI filing.
Review unpaid employee liabilities
This guidance is not a substitute for tailored advice in several cases. These include self-employed workers and overseas employers. They also include non-RCA tokens, third-party payments, employment-related securities arrangements, and discretionary crypto incentives.
Before the next payroll run, reconcile GBP gross pay, deductions, BTC transfer, and FPS figures. Ask a UK tax adviser for tailored advice if the arrangement falls outside ordinary wages. That check is most useful before the first Bitcoin payment, not after it.
Frequently asked questions
Do Bitcoin wages still need PAYE in the UK?
Yes. Bitcoin paid as employee remuneration will commonly be an RCA. The employer should value it in GBP on payday, deduct PAYE and NIC, and report it through RTI.
Can my employer pay all my salary in Bitcoin?
Potentially, but the contract and deduction method must work first. The employer must still fund PAYE and NIC in pounds. This can be through net settlement, cash reimbursement, or a gross-up.
When must an employer submit an FPS for Bitcoin?
The FPS must normally be sent on or before the employee's payday. The later HMRC payment deadline is usually the 22nd of the following tax month. That date applies to electronic payments.
Do I pay Capital Gains Tax when I sell Bitcoin?
Possibly. The GBP value already taxed as employment income is generally your acquisition cost. A later sale, swap, or spend can create a Capital Gains Tax calculation.
Can an employer use one daily Bitcoin price for payroll?
Only if that method matches the agreed relevant payment point and is applied consistently. A timestamped price near the transfer time gives stronger evidence. An undocumented closing price gives weaker evidence.
Make the next pay run GBP-led
A Bitcoin wage arrangement is easier to control when gross pay, deductions and RTI remain in GBP. Treat the Bitcoin transfer as the way net pay is delivered. Do not treat it as a way to step outside PAYE.
