Crypto Tax De Minimis UK — Annual Exempt Amount Guide
Not every crypto investor owes tax. This guide explains the Annual Exempt Amount, when you may be below the reporting threshold and what records you still need to keep. Educational only — not tax advice.
Check if I owe crypto tax →The Annual Exempt Amount (AEA)
For 2025/26, the CGT Annual Exempt Amount is £3,000 per individual. Net gains below this amount are not chargeable to Capital Gains Tax. Losses in excess of the AEA can be carried forward to future years.
When do you still need to report?
Even if your net gains are below £3,000, you may still need to complete a Self Assessment if your total disposal proceeds in the tax year exceed £50,000. If both your gains are under £3,000 AND your proceeds are under £50,000, you typically do not need to report crypto on Self Assessment.
Income Tax threshold
If you receive crypto as income (staking, airdrops, referral bonuses, P2E rewards), the income is combined with your other income. You will owe Income Tax only if your total income exceeds your Personal Allowance (£12,570 for 2025/26).
Frequently asked questions
If my crypto gains are under £3,000, do I need to file anything?
Not necessarily — if your total disposal proceeds are also under £50,000 and you have no other Self Assessment obligations, you may not need to file. But keep your records in case HMRC asks later.
Can I use the de minimis threshold to avoid CGT by selling small amounts?
Using the AEA by realising gains up to £3,000 each year is a legitimate tax-planning strategy. However, the 30-day bed-and-breakfast rule means you cannot immediately buy back the same asset.
