Income Tax bands

Relevant if you earn crypto through mining, staking, airdrops, or any other income-producing activity.

Basic rate£12,571 to £50,27020%
Higher rate£50,271 to £125,14040%
Additional rateOver £125,14045%

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.

31 May 2027CARF: 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:

TriggerThreshold
Total disposal proceedsOver £50,000
Net capital gainsOver £3,000
Miscellaneous income (staking, mining)Over £1,000 (Trading Allowance)
Self-employed trading profitsOver £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.
