Tax & Regulation
How is crypto mining taxed in the UK?
HMRC taxes mining based on trade vs hobby classification. Trade status unlocks full business expense deductions. See how CGT applies on coin sales.
HMRC treats crypto mining income based on whether your activity is a trade or a hobby. This distinction is critical because it determines what expenses you can deduct.
| Classification | Tax Treatment | Expenses Deductible? | NI Contributions? |
|---|---|---|---|
| Hobby (miscellaneous income) | Income Tax on value at receipt | Limited (some electricity) | No |
| Trade (trading income) | Income Tax on net profit | Yes — full business expenses | Possibly |
When you later sell your mined coins: Capital Gains Tax applies only to the increase in value since you received them. Your cost basis for CGT is the market value at the time of mining — so you don't get taxed twice on the same value.
🎯 Example: You mine 10,000 MEWC when price = £0.00003 (total value = £0.30 — effectively zero income tax). Later you sell at £0.002 (ATH). Your CGT is on the £19.70 gain, minus your £3,000 annual allowance. For most hobby miners, no CGT is due at all because the annual allowance covers it.
