Crypto Mining Taxes 2026: Income, Expenses, and Deductions
Complete guide to crypto mining taxes. Mining income at FMV, hobby vs business determination, deductible expenses including electricity and hardware depreciation, and pool mining.
How Crypto Mining Is Taxed
Crypto mining creates two distinct tax events. First, receipt of mining rewards is taxable as ordinary income when the coins hit your wallet, valued at fair market value on that date. Second, when you later sell or trade the mined coins, you have a capital gain or loss — with cost basis equal to the FMV at the time of mining (the amount you already included in income).
This two-stage structure means miners can end up paying twice: income tax on receipt (at up to 37%), then capital gains tax when they sell (at up to 20% long-term). Tax planning — especially around when to sell — is critical for miners.
Hobby vs. Business Mining: The Critical Distinction
The IRS uses a nine-factor test to determine whether a mining operation is a for-profit business (Schedule C) or a hobby (Schedule 1, with limited deductions).
Factors that suggest business status
- You operate in a businesslike manner (separate accounts, records, business plan)
- You devote significant time and effort to the activity
- You depend on the income for your livelihood
- Your losses are typical for the startup phase of a business, not indefinite
- You have a profit in at least 3 of the last 5 years (safe harbor, but not required)
- You have expertise in the field or consult experts
Hobby mining
If mining is a hobby, income is reported on Schedule 1 as other income. Expenses are not deductible — the old itemized deduction for hobby expenses was eliminated by the Tax Cuts and Jobs Act (TCJA) and has not been reinstated through 2026. This creates a brutal situation: you pay full income tax on mining rewards with no offset for electricity or hardware.
Business mining
If mining is a business, you file Schedule C and deduct all ordinary and necessary business expenses against your mining income. Net profit from Schedule C is also subject to self-employment tax (15.3% on first ~$168,600 in 2026, 2.9% above that), which can offset some of the income tax benefit.
Deductible Business Mining Expenses
Electricity
Electricity is typically the largest mining expense. Keep monthly utility bills and a log of your mining hardware's power draw. If you mine from home, you can deduct the portion of electricity attributable to mining (kWh used by miners / total household kWh). This requires documentation — just estimating isn't sufficient for an audit.
Mining hardware
ASICs, GPUs, and other mining hardware are business assets. You can deduct their cost through:
- Section 179 expensing: Deduct the full purchase price in the year of purchase (up to $1,160,000 in 2026), reducing taxable income immediately. Recapture applies if you stop using the equipment for business within the recovery period.
- Bonus depreciation: Deduct a percentage of the asset's cost in year one. For 2026, bonus depreciation is phasing down — consult your tax advisor for the current percentage.
- Regular MACRS depreciation: 5-year or 7-year recovery period for computing equipment, spreading the deduction over multiple years.
Other deductible expenses
- Internet service (proportional to mining use)
- Cooling equipment (fans, AC units used for the mining operation)
- Rack space, colocation fees, or data center contracts
- Mining pool fees (deductible as a business expense, or netted against income)
- Software, monitoring tools, and subscriptions
- Home office deduction (if a dedicated space is used exclusively for mining)
- Professional fees (accountant, attorney)
Pool Mining vs. Solo Mining
The tax treatment is the same regardless of how you mine:
- Pool mining: You receive frequent small payouts from the pool. Each payout is income at FMV on the date received. Most pools provide a payout history — export it and import into your tax software.
- Solo mining: You receive the full block reward only when you find a block (rare for most individual miners). The entire block reward is income at FMV when received.
- Mining pool fees: Pools typically take 1–3% of rewards. This can be treated as a reduction in income or a deductible expense (same result).
Mining vs. Staking: Different Tax Profiles
Mining (proof-of-work) and staking (proof-of-stake) are both income at receipt, but they differ in deductibility and business context:
- Mining has clear business expenses (electricity, hardware) that are deductible if operated as a business
- Staking has minimal direct expenses (just the validator hardware/software for node operators)
- Mining requires active participation and creates clearer "trade or business" argument; staking can be purely passive
- See our staking rewards guide for staking-specific tax treatment
Record Keeping for Miners
Blockchain Smart Tax can import your mining wallet address and reconstruct your complete mining history from the blockchain — including the FMV of each reward at receipt. This creates a complete income record without requiring manual spreadsheets.
Keep separately: utility bills, hardware purchase receipts, pool fee statements, and any business formation documents. These support both the income figures and the deduction claims.
