Crypto Mining Tax 2025 — US

Crypto mining is taxed in two events: ordinary income at receipt, then capital gains/loss when you sell the mined coins. The big choice is hobby vs business — it determines whether you can deduct electricity, hardware depreciation, and other expenses.

The two tax events

Event 1: Receipt of mining rewards

Per IRS Notice 2014-21, mining rewards are ordinary income at USD fair market value when you receive them. For solo miners, that's the moment your block is accepted. For pool miners, it's typically each payout from the pool.

Event 2: Sale of mined coins

Capital gain/loss = sale price − cost basis. Cost basis = FMV recognized as income at receipt. Holding more than 365 days from receipt → long-term rates.

Hobby vs business — the most important decision

Hobby treatment

  • Income reported on Schedule 1 as "Other income"
  • No expense deductions (post-TCJA, hobby expenses are not deductible 2018–2025)
  • No self-employment tax (15.3%)
  • You pay only ordinary income tax on the gross mining income

Business treatment (Schedule C)

  • Income reported on Schedule C
  • Deduct all related expenses — electricity, hardware depreciation, internet, rented hosting, repairs, supplies
  • Subject to 15.3% self-employment tax on net profit
  • Net loss can offset other ordinary income
  • Qualified Business Income (QBI) deduction may apply (up to 20% off taxable income)

Which qualifies as a business?

IRS factors (Treas. Reg. 1.183-2):

  1. Manner of operation (records, business plan)
  2. Expertise of the operator
  3. Time and effort spent
  4. Expectation of asset appreciation
  5. Past success in similar activities
  6. Financial status (mining is your livelihood vs hobby income)
  7. Element of personal pleasure (mining as trade vs hobby)

Practical safe harbor: if you have multiple ASICs or 3+ GPUs, dedicated electricity service, business records, and treat it like a business → it's a business. A single GPU mining rig running on your home outlet without dedicated metering looks like a hobby.

Worked example — business mining

You operate 5 ASICs (Bitcoin, Antminer S21). 2025 results:

  • Mining rewards: 0.85 BTC, FMV at receipt averaging $96,000 = $81,600 income
  • Electricity (sub-metered): $14,400/year ($0.10/kWh × 14,400 kWh, ~3.3 kW × 24 × 365)
  • Hardware depreciation (Section 179): $26,000 (5 ASICs at $5,200 each, fully expensed)
  • Internet, hosting, supplies: $1,200
  • Repairs, fans, replacement parts: $800

Net profit: $81,600 − $42,400 = $39,200

  • Self-employment tax (15.3% on 92.35% of net): $5,533
  • Half of SE tax deductible: $2,766
  • QBI 20% deduction (if eligible): $7,840
  • Federal income tax on net (assuming 22% bracket): ~$6,200
  • Total federal tax: ~$11,733

Compare to hobby treatment: $81,600 fully taxable at 22% = $17,952. Plus capital gains tax later when selling. Business saves ~$6,000/year here.

Section 179 vs MACRS depreciation

Mining hardware (ASICs, GPUs) is 5-year property under MACRS. Two options:

  • Section 179: expense up to $1,160,000 (2025) in year placed in service. Limited to net business income — can't create a loss.
  • MACRS 5-year: standard depreciation schedule — 20% / 32% / 19.2% / 11.52% / 11.52% / 5.76% across 6 years.
  • Bonus depreciation: 60% in 2025 (phasing down from 100% in 2022). Can be combined with §179.

For most home mining setups under $50k, full Section 179 expensing in year 1 is optimal.

Electricity record-keeping

Sub-meter your mining rig. A $50 P3 Kill-A-Watt or $200 hardwired sub-panel meter pays for itself by giving you defensible electricity records.

Acceptable approximations if no sub-meter:

  • Wattage rating × runtime hours × utility rate
  • Nameplate watts of all mining equipment, multiplied by 90% (typical real-world derating), times runtime
  • Whole-home electricity bill increase month-over-month after starting mining (if pre-mining baseline available)

Home office for mining

If you have a dedicated room or area for mining (and the mining is a business, not hobby), you may deduct that area as a home office:

  • Square-foot percentage method: $5/sqft up to 300 sqft (simplified) or actual costs (utilities, insurance, depreciation)
  • Must be exclusively for the mining business — not a multi-use space

State tax considerations

  • Texas: no state income tax, low electricity rates, mining-friendly regulation. Best US state for mining.
  • Wyoming: no state income tax, blockchain-friendly legislation
  • New York: state income tax, NY moratorium on certain mining facility types extended through 2026
  • Washington: no income tax, but rising electricity rates and recent restrictions on bulk mining
  • Other no-income-tax states: Alaska, Florida, Nevada, NH (no wage tax), SD, Tennessee (no wage), Texas, WA, Wyoming

Common mining tax mistakes

  1. Reporting only the sale, not the receipt. Most common error. You owe income tax on the receipt FMV, not just capital gains on later sale.
  2. Hobby treatment when you should be business. Cost yourself thousands in unclaimed deductions.
  3. Business treatment when you don't qualify. Can trigger §183 hobby loss audit; lose deductions retroactively.
  4. Missing electricity records. The single biggest deduction; without sub-meter you weakens your audit position.
  5. Wrong FMV for receipt. Use the day's average price (or block-time price for solo miners) consistently.

Software for miners

Koinly integrates with major mining pools (F2Pool, AntPool, Foundry, Luxor, Mining Pool Hub, etc.) and auto-pulls receipt timestamps with FMV. Schedule C export coming in 2026.

CoinLedger handles mining receipts cleanly and exports Schedule C-ready CSVs that TurboTax Self-Employed accepts directly.
