Crypto Tax in the UK: What You Must Know Before HMRC Comes Calling

Not long ago, I spoke with a small business owner who had started investing in crypto. He was proud of his early gains — buying low, swapping coins, and watching his wallet grow.

Then one morning, a brown envelope arrived from HMRC.

Inside was a letter requesting that he explain his cryptocurrency transactions. He was confused. “I never even sold to cash,” he said. “I just swapped Bitcoin for Ethereum.”

That’s when he learned a crucial lesson:

HMRC treats crypto swaps as sales, and that means Capital Gains Tax.

When Do You Owe Tax on Crypto in the UK?

According to HMRC, you may owe Capital Gains Tax on crypto if you:

• Sell crypto for cash,

• Swap one cryptocurrency for another,

• Spend crypto to buy goods or services, or

• Gift crypto (except to your spouse or civil partner).

Each of these actions is considered a “disposal”, and HMRC wants you to report any profit made.

If you receive crypto through:

• Mining or staking,

• Freelance work or business transactions,

• Airdrops or bonuses,

then it’s classed as income, not investment. That means Income Tax and National Insurance may apply instead.

HMRC Crypto Rules Are Tightening

If you’ve been thinking, “They’ll never find out”, think again.

• The Capital Gains Tax allowance has been reduced, so more crypto investors are now liable.

• From January 2026, new global reporting standards (the Crypto-Asset Reporting Framework) will require crypto exchanges to share user data with HMRC.

In short — HMRC will know who’s trading, how much, and when.

Your “private wallet” isn’t as private as it once seemed.
