Monero (XMR) Tax UK: Privacy Coins and Why HMRC Still Expects a Return
How HMRC taxes Monero in the UK — Capital Gains Tax applies just like any crypto, why privacy doesn't remove the obligation, and how to keep records when exchanges have delisted XMR.
Monero is built to be private — ring signatures, stealth addresses and confidential amounts hide who sent what to whom. A common assumption follows: if HMRC cannot see it, it cannot be taxed. That is a misreading of how UK tax law works, and a risky one.
Privacy is not exemption
HMRC taxes Monero exactly like any other cryptoasset. Selling XMR for GBP, swapping it for BTC, or spending it is a Capital Gains Tax disposal, measured against your Section 104 pooled cost after the same-day and 30-day rules. Gains above the £3,000 annual exempt amount are taxed at 18% or 24%. If you mine XMR, the coins are income at their GBP value on receipt. The duty to report sits with you regardless of whether the chain is traceable — the privacy of the network changes nothing about the law.
The delisting problem
Several major exchanges have removed Monero for UK and EU customers in recent years, partly in response to tightening regulation. That pushes acquisition and disposal towards peer-to-peer trades, decentralised swaps and atomic swaps — none of which hand you a tidy transaction statement. The practical consequence is that record-keeping falls entirely on you.
Valuing disposals in GBP
Because you may have no exchange record, you need a defensible GBP price for each transaction. Use a reputable price source for XMR/GBP at the date and time of each disposal and acquisition, and save a snapshot. Consistency matters more than picking any single "correct" feed — apply the same method throughout the year.
CARF and the bigger picture
The Crypto-Asset Reporting Framework, live from 2026, expands what platforms report to HMRC. Privacy coins are harder to surface this way, but accurate self-reporting and, where needed, voluntary disclosure remain the only compliant path — and HMRC's penalties for deliberate non-disclosure are far heavier than the tax itself.
Because Monero's chain cannot be scanned from a public address, enter your XMR buys and sells into the CryptoLens UK calculator to apply Section 104 pooling and produce a defensible figure for your return.

Frequently asked questions
Does HMRC tax Monero even though it's private?
Yes. HMRC taxes XMR like any cryptoasset — Capital Gains Tax on disposals and Income Tax on mined coins. The privacy of the network does not remove your legal duty to report.
How do I record Monero transactions with no exchange statement?
Log the date, amount and a GBP value from a reputable price source for every buy and sell, and keep a consistent method. You are responsible for a defensible cost basis even without an exchange export.
