Capital Gains Tax
The tax year runs from 6 April 2026 to 5 April 2027.
| Rate / Threshold | Figure | Note |
|---|---|---|
| Annual exempt amount | £3,000 | Applies to all capital gains, not just crypto |
| Basic-rate CGT | 18% | Gains within the basic-rate income band |
| Higher-rate CGT | 24% | Gains above the basic-rate threshold |
| 30-day matching rule | 30 days | A repurchase can be matched to the earlier disposal instead of the pooled cost |
| Loss registration deadline | 4 years | From end of the tax year the loss arose |
Worth knowing: the CGT allowance was £12,300 in 2022/23. It has fallen by 76%. The £3,000 figure applies in 2024/25, 2025/26 and 2026/27.
Income Tax bands
Relevant if you earn crypto through mining, staking, airdrops, or any other income-producing activity.
| Band | Taxable Income | Rate |
|---|---|---|
| Personal allowance | Up to £12,570 | 0% |
| Basic rate | £12,571 to £50,270 | 20% |
| Higher rate | £50,271 to £125,140 | 40% |
| Additional rate | Over £125,140 | 45% |
The personal allowance tapers to zero for income above £100,000 (at £1 for every £2 over the threshold). Effective marginal rate between £100,000 and £125,140 is 60%.
These bands apply in England, Wales and Northern Ireland. Scotland has separate Income Tax bands and rates.
National Insurance for crypto earners
Capital gains are not subject to National Insurance. Income from crypto activities (mining profits classified as trading, employment income paid in crypto) may attract NI contributions.
| Class | Who pays | Rate 2026/27 |
|---|---|---|
| Class 2 | Voluntary if self-employed profits are below £7,105 | £3.65/week |
| Class 2 credit | Self-employed profits of £7,105 or more | Treated as paid |
| Class 4 | Self-employed trading profits £12,570 to £50,270 | 6% |
| Class 4 upper | Self-employed trading profits above £50,270 | 2% |
Key dates and deadlines
| Date | What happens |
|---|---|
| 6 April 2026 | 2026/27 tax year begins |
| 5 April 2027 | 2026/27 tax year ends. Final day for disposals to count in this year. |
| 5 October 2027 | Deadline to register for Self Assessment if you have not filed before |
| 31 October 2027 | Paper Self Assessment filing deadline |
| 31 January 2028 | Online Self Assessment filing deadline and tax payment deadline |
| 31 January 2028 | First payment on account for 2026/27 also due |
| 31 May 2027 | CARF: reporting providers submit first reports to HMRC covering 2026 data |
CARF (Crypto-Asset Reporting Framework) requires in-scope reporting providers to collect identifying and transaction information. Their first reports cover 2026 activity and are due by 31 May 2027. This increases HMRC's visibility but does not replace your own records.
Reporting thresholds
Depending on your circumstances, you may need to report if the following apply in 2026/27. The £50,000 disposal test is relevant when completing the capital-gains section of a Self Assessment return:
| Trigger | Threshold |
|---|---|
| Total disposal proceeds | Over £50,000 |
| Net capital gains | Over £3,000 |
| Miscellaneous income (staking, mining) | Over £1,000 (Trading Allowance) |
| Self-employed trading profits | Over £1,000 |
If you already complete Self Assessment, total disposal proceeds above £50,000 can require the capital-gains pages even when the net gain is modest. Check the current HMRC reporting route for your circumstances.
Disclaimer
This is not financial or tax advice. Rates and thresholds are subject to change in future budgets. Individual circumstances vary. Verify figures directly with HMRC or a qualified tax adviser before filing.
