Tax & Regulation
What expenses can I deduct as a mining business?
Deduct mining rigs (AIA), electricity, internet, cooling, pool fees, replacement parts, accounting, and dedicated space. See example savings.
If HMRC classifies your mining as a trade, you can deduct all legitimate business costs from your mining income before calculating tax.
| Expense | Deduction Type | Example ({rig.name}) |
|---|---|---|
| Mining rig / GPUs | Capital Allowance (AIA) | £28,000 — Year 1 |
| Electricity | Operating expense | £1016/year — £10162/10yr |
| Internet connection | Proportional expense | % used for mining |
| Cooling / ventilation | Operating expense | Fans, ducting, etc. |
| Software / pool fees | Operating expense | Mining pools typically 1% |
| Replacement parts | Revenue expense | Replacement fans, cables, thermal paste |
| Accounting fees | Business expense | Tax return preparation |
| Dedicated space | Proportional expense | % of home used exclusively for mining |
🎯 Total potential deduction (Miner 1000, 10yr): £28,000 (AIA) + £10162 (electricity) = £38,161.6. At 20% basic rate, this saves ~£7632 in Income Tax. A DCA buyer spending the same amount gets zero deductions.
ℹ️ Keep detailed records of all expenses with receipts. HMRC may request evidence if you're audited. A dedicated electricity meter for your mining operation is ideal.
