Crypto mining tax in the UK
UK crypto miners face tax on two fronts: Income Tax when mining rewards are received, and Capital Gains Tax when those tokens are later sold or swapped. Whether you are a hobby miner or running a commercial operation significantly affects the rates and rules that apply. Educational only — not tax advice.
Estimate my mining tax →Hobby miner vs commercial miner
HMRC distinguishes between mining as a hobby (miscellaneous income) and mining as a trade (self-employment income). Relevant factors include: the scale of the operation, use of commercial premises, degree of organisation and investment, frequency and regularity of activity, and whether the activity is conducted in a business-like manner. Most small-scale home miners are treated as hobby miners.
Income Tax on mining rewards — hobby miners
For hobby miners, tokens received from mining are typically subject to Income Tax as miscellaneous income at their GBP value on the date of receipt. The £1,000 trading allowance may cover very small amounts. Above £1,000, the full amount is typically taxable at your marginal Income Tax rate.
Income Tax and NICs — commercial miners
If mining constitutes a trade, profits (revenue minus allowable expenses) are subject to Income Tax as self-employment income, plus Class 4 National Insurance. Allowable expenses for a mining trade may include electricity costs, hardware depreciation, internet, and software.
Capital Gains Tax when you sell mined tokens
When you later sell or swap tokens received from mining, Capital Gains Tax may apply. The cost basis of mined tokens is the GBP value at the time of receipt (which you already declared as income). CGT is calculated on any further gain above that cost basis, subject to the £3,000 annual exempt amount.
Frequently asked questions
Can I deduct electricity costs from my mining income?
For commercial miners (trading basis), electricity used wholly and exclusively for mining may be deductible. For hobby miners, HMRC's guidance on deducting expenses against miscellaneous income is more restrictive. Consider speaking to a qualified accountant if your electricity costs are significant.
I mine using a mining pool — is the treatment different?
No — rewards distributed from a mining pool are still treated as income at their GBP value on the date of receipt, in the same way as solo mining rewards.
What if I was paid in a token that has since crashed?
Your Income Tax was on the GBP value when you received it — regardless of what happened to the price since. If the tokens have since fallen in value and you've sold them at a loss, you may be able to offset that capital loss against other gains.
Does PoS staking count as mining for tax purposes?
HMRC's guidance treats Proof of Stake staking rewards separately from Proof of Work mining. Staking rewards are typically treated as miscellaneous income (similar to hobby mining) rather than trading activity. See our dedicated staking tax guide.
