# When do you need to report crypto to HMRC?

Report crypto to HMRC if: net capital gains exceed the £3,000 annual exempt amount (2025/26); total disposal proceeds exceed £50,000 in the year; you received taxable crypto income (staking, mining, pay); or you must file Self Assessment for other reasons. Simply holding crypto with no disposals usually requires no report.

## Key facts
- Tax year runs 6 April to 5 April.
- £3,000 annual exempt amount for all CGT gains combined.
- £50,000 proceeds rule can require SA108 even with no tax due.
- Income from crypto is separate from capital gains.
- CARF gives HMRC exchange data from 2026 — still file yourself.
- Deadline: register by 5 October, file and pay by 31 January.

## Hold only — no disposals

If you bought crypto and did not sell, swap, spend or gift it during the tax year, you generally have no capital gains to report. Price going up on screen is not taxable until you dispose.
## Capital gains above the allowance

When you dispose of crypto, calculate net gains after losses and the Section 104 pool. If total net gains on all chargeable assets exceed £3,000 (2025/26), register for Self Assessment and report on SA108.
## The £50,000 disposal proceeds rule

Even if your gain is below £3,000, you may need to report on SA108 if total proceeds from disposals of chargeable assets (including crypto) exceed £50,000 in the tax year. Proceeds means what you received in pounds, not profit. HMRC uses this to capture high-volume traders who might offset gains with losses.
## Income triggers

Report Income Tax if you received crypto from employment, mining, staking, airdrops for services, or DeFi rewards. The £1,000 trading allowance may cover minor miscellaneous income — see HMRC guidance on receiving cryptoassets.
## CARF and HMRC matching

From 2026, UK exchanges report customer data to HMRC. Undeclared tax remains your responsibility. If you receive an HMRC nudge letter, respond promptly — see our penalties and disclosure guides.

## FAQs
### Do I report every small swap?

Swaps are disposals. Many small swaps add up — track cumulative proceeds and gains across the tax year.
### Is there a real-time CGT report for crypto like property?

No. UK crypto is reported through annual Self Assessment, not the 60-day property reporting service.
