Getting Paid in Crypto in the UK: How Salary Tax Actually Works

London — Crypto salaries have quietly moved from Web3 startups into the ordinary job market: a developer taking 20% of pay in bitcoin, a designer invoicing a DAO in stablecoins, a UK employee of an overseas exchange paid partly in the company token. The arrangements vary; the tax treatment doesn't. HMRC has had detailed rules on crypto pay for years, and they're stricter — and stranger — than most employees assume.

The headline is simple. The footnotes are where people get hurt.

The headline: it's income, taxed on day one

Crypto received from employment is employment income, full stop. The sterling value of the tokens on the date you receive them is what gets taxed — income tax and National Insurance contributions, exactly as if the same value had arrived as pounds, per HMRC's guidance on receiving cryptoassets.

Note what that means in a volatile market. You're taxed on the value at receipt. If the tokens halve before you sell them, you still owed tax on the higher figure; if they double, the growth is a separate matter for capital gains tax later. Plenty of people paid in crypto during past bull markets learned the first half of that sentence painfully.

PAYE and the "readily convertible asset" question

Whether your employer must run the tax through payroll depends on whether the tokens count as readily convertible assets — broadly, tokens with trading arrangements that make them easy to turn into cash. HMRC's cryptoassets manual is explicit that exchange tokens like bitcoin fall into this category.

For RCA tokens, the employer must operate PAYE: they estimate the sterling value of the crypto at payment and account for income tax and NICs through payroll before you're paid. For the rarer non-RCA case — illiquid tokens with no real market — there's no PAYE, and the duty shifts to you to declare the income through self-assessment.

If you're negotiating a crypto-pay arrangement, this is the first competence test of your employer. One that talks confidently about PAYE on the tokens has done this before. One that suggests paying you in bitcoin "off payroll" is volunteering you for a tax problem.

The 90-day rule nobody mentions

Here's the genuinely obscure trap. When an employer pays PAYE on crypto wages, the tax money has to come from somewhere — and since they paid you in tokens rather than pounds, they've often fronted it. The rules require the employee to make good that amount to the employer within 90 days of the end of the tax year. Miss the window, and the amount the employer covered becomes a further taxable benefit, generating another round of income tax and NICs on top.

It's a circular, bureaucratic little rule, and it catches precisely the people doing everything else right. If part of your pay arrives in crypto, ask payroll directly how the due amount is being settled — usually it's deducted from the sterling portion of your salary, which solves the problem invisibly. "Usually" is not "always."

Selling later: round two with CGT

Tax at receipt is only the first event. The tokens then sit in your hands as a capital asset, with an acquisition cost equal to the value already taxed as income. Sell, swap or spend them later and any movement since receipt is a capital gain or loss — reportable once your gains pass the £3,000 annual exempt amount.

The practical habit that makes all of this manageable is one spreadsheet line per pay packet: date, tokens received, sterling value at receipt. That single record is both your proof of income taxed and your CGT base cost. Without it, you're reconstructing prices years later for an asset you received twelve times a year.

Worth doing?

Sometimes, genuinely. Crypto pay suits people who'd be buying the assets anyway — it's pound-cost averaging with extra steps removed. But take the boring advice: keep enough of your salary in sterling to live on and to cover every tax charge the crypto portion creates. Volatile pay plus fixed tax obligations is a cash-flow problem dressed as a perk, and HMRC bills in pounds, on time, regardless of what the chart did this month.
