ASIC Mining Equipment: UK Tax, VAT and Capital Allowances

Buying an ASIC miner for a business does not create one universal tax deduction. The purchaser must separately consider:

1. accounts: whether the hardware is a fixed asset, stock, leased equipment or another category;
2. direct tax: whether capital allowances or an allowable revenue deduction can reduce taxable profits; and
3. VAT: whether input tax is recoverable by a VAT-registered person making supplies that carry a right to deduct.

Accounting depreciation is not itself a tax deduction. Capital allowances commonly provide the tax relief for qualifying plant and machinery. A deduction reduces taxable profit; it is not a promise of a cash refund, recovery of the purchase price or a fixed percentage saving.

Qualification depends on the business, ownership, use, timing, financing, connected businesses and the exact equipment. A company name on an invoice or checkout does not prove a qualifying trade, exclusive business use or VAT recovery entitlement.

Dedicated ASIC hardware used in a qualifying mining trade may be capable of treatment as plant or machinery, but classification remains fact-specific. It is not normally deducted as a day-to-day revenue expense merely because it earns mining receipts.

Current capital-allowance routes can include:

• Annual Investment Allowance (AIA): a 100% allowance for qualifying expenditure on most plant and machinery, subject to the current £1 million annual limit, claimant eligibility, shared limits and exclusions. Qualifying second-hand equipment may be eligible even though it is excluded from some first-year allowances.
• Full expensing and the 50% first-year allowance: available only to companies for qualifying new and unused plant or machinery, subject to statutory conditions and exclusions.
• 40% first-year allowance: for qualifying new and unused main-rate plant or machinery bought on or after 1 January 2026 where its conditions are met.
• Writing-down allowances: where immediate relief is unavailable, not chosen or exceeds a limit. From April 2026 the main-pool rate is generally 14% and the special-rate pool remains 6%, with transitional calculations for periods spanning the change.

Disposals can produce disposal values and balancing charges. Private or non-business use restricts relief, and assets used for leasing, bought under hire purchase, transferred from personal use or acquired from connected parties need specific review. Non-trading miscellaneous mining income does not normally carry an entitlement to capital allowances.

Check current GOV.UK guidance for capital allowances, AIA, full expensing and the 40% first-year allowance before claiming.

Where mining is a trade, revenue costs incurred wholly and exclusively for that trade may be deductible under the ordinary rules. Depending on the facts, these can include metered electricity, hosting charges, pool fees, connectivity, qualifying repairs and maintenance, insurance, accounting and other directly related costs. Capital improvements and the acquisition of equipment follow capital rules instead.

Mixed business and private use must be apportioned on a reasonable, supportable basis. A domestic electricity bill cannot simply be deducted in full because a miner operates at the premises. Retain dedicated meter readings where practicable, tariff periods, standing charges, machine uptime, power settings, hosting statements and the method used to allocate shared costs.

A cost cannot be deducted twice. In particular, HMRC says mining equipment and electricity are not allowable acquisition costs of the mined tokens for capital-gains purposes, although qualifying expenses may be considered in calculating trading or miscellaneous income under the relevant rules. Pool fees deducted before payout should still be evidenced so the accountant can determine gross and net reporting.

VAT recovery is not automatic. A purchaser generally needs to be VAT registered, hold valid evidence such as a VAT invoice in the correct business name, and show a direct link between the cost and business supplies carrying a right to deduct. Recovery can be restricted for private, non-business or exempt activity and may require attribution or partial-exemption calculations.

HMRC currently states that exchange tokens received from mining are generally outside the scope of VAT because there is an insufficient link between the service and consideration and no customer for the mining service. That classification can make input-tax recovery for a mining-only activity difficult or unavailable. It does not follow that every VAT-registered miner can reclaim the VAT on ASIC hardware or electricity. A business that also makes taxable supplies, provides contracted hashpower or receives pool-related consideration must analyse the precise supply and its VAT treatment.

For purchases from abroad, retain the customs declaration, import VAT statement or postponed-accounting evidence and confirm the importer of record. For services bought from an overseas pool, hosting provider or software supplier, consider the place-of-supply and reverse-charge rules. For high-value computer equipment, the VAT Capital Goods Scheme may also require later use adjustments.
