US crypto mining taxes in 2026: income, basis, expenses and reporting
US crypto mining can create two separate tax events: ordinary income when a reward is received and a later gain or loss when the mined asset is sold, exchanged or spent. The IRS does not automatically treat every miner as a business, and it does not make every electricity or hardware cost deductible. A reliable calculation must establish the reward timestamp and USD value, the taxpayer's business or nonbusiness facts, the basis created by reported income and every later disposal. This guide follows current IRS material and avoids treating a pool dashboard estimate as a complete tax return.

Start for free →IRS Notice 2014-21 states that a taxpayer who successfully mines virtual currency includes the reward's fair market value in gross income as of the date of receipt. The value must be measured in US dollars using a reasonable, consistently documented market source. The rule applies to the reward itself; it is not postponed until the miner converts the asset to dollars.
"Receipt" still requires a factual timestamp. A coin credited to a wallet that the taxpayer can control is different from an estimated pool balance that has not reached a payout threshold and cannot be transferred. Record the pool's credit and payout rules, the on-chain timestamp, the wallet address, the amount and when the taxpayer obtained control. Do not choose whichever timestamp produces the lowest price.
| Mining record | Tax purpose | Common error |
|---|---|---|
| Reward quantity and asset | Measures the property received | Reporting only cash withdrawals |
| Date and time of receipt | Fixes the income year and valuation time | Using the later sale date |
| USD fair market value | Measures ordinary income and initial basis | Using a current price for an old reward |
| Pool fee and payout details | Supports the gross-versus-net reconciliation | Recording only a net wallet amount without the statement |
| Wallet and transaction hash | Connects the reward to later transfers and disposals | Importing the same pool payout twice |
The receipt value is income even if the token later falls. A later decline does not reverse the original income. It can produce a separate capital or business loss only when the later event and asset character support one.
Schedule C business mining versus nonbusiness mining
The IRS does not provide a one-click election that turns mining into a trade or business. Classification follows the complete facts: continuity, regularity, scale, time and effort, profit objective, operational records and the way the activity is conducted. Owning an ASIC is relevant but not decisive; occasionally running a spare GPU is not automatically a business either.
The IRS digital-assets page directs nonbusiness ordinary income from mining to the applicable Form 1040 or Schedule 1 route. If mining is carried on as a sole-proprietor trade or business, gross receipts and allowable business expenses generally flow through Schedule C. Notice 2014-21 says that net earnings from a nonemployee mining trade or business constitute self-employment income and are subject to self-employment tax. Schedule SE, the Social Security wage base, other earned income and additional Medicare rules can affect the final amount, so multiplying gross rewards by one headline percentage is not a reliable calculation.
| Question | Nonbusiness activity | Trade or business |
|---|---|---|
| Reward at receipt | Ordinary income | Business gross income |
| Typical federal reporting path | Form 1040 / Schedule 1 as applicable | Schedule C and potentially Schedule SE |
| Expenses | Do not assume hobby expenses are deductible | Only substantiated ordinary and necessary business expenses |
| Later coin sale | Often a capital-asset disposal | Character depends on how the coin is held in the business |
Document the conclusion before filing. A label selected inside tax software cannot override the actual operation. Material multi-rig activity, an entity, employees, inventory questions or mixed personal and business use should be reviewed with a qualified US tax professional.
Electricity, hardware and other mining costs
Business status does not make every payment deductible. A sole proprietor generally needs a business purpose, substantiation and a reasonable allocation between business and personal use. The timing can also differ: a current operating expense is not the same as a capital asset that may need depreciation. Current Section 179, bonus-depreciation, listed-property, start-up and home-office rules depend on the tax year and taxpayer, so this guide does not promise an automatic full write-off.
- Electricity: retain utility bills, rig power measurements, operating hours and the allocation method. Whole-home electricity is not a mining deduction without support.
- ASICs, GPUs and infrastructure: keep invoices, placed-in-service dates, business-use percentages, repairs, disposals and depreciation records.
- Pool, hosting and software fees: preserve the contract and gross reward reconciliation; do not count a fee twice.
- Internet, rent and cooling: deduct only the supported business portion under the applicable rules.
- Home office: the mining location must satisfy the specific home-office rules; equipment occupying a room does not by itself establish eligibility.
For a mixed-use device, retain contemporaneous logs instead of applying a round percentage at year end. For hosted mining, distinguish ownership of equipment from the purchase of a service or a purported investment contract. Cloud-mining and hash-rate products can have legal and tax terms different from direct operation of owned equipment.
Cost basis and the later sale of mined crypto
When mining income is included at USD fair market value, that included value generally establishes basis in the reward. The same number should connect the income ledger to the asset ledger. A mined coin does not have confirmed zero basis merely because no exchange purchase exists.
Suppose a nonbusiness miner receives 0.01 BTC when it is worth USD 900. The USD 900 is ordinary income at receipt and becomes the starting basis of that lot. If the miner later sells it for USD 1,150 and pays a USD 10 selling fee, the simplified amount realised is USD 1,140 and the capital gain is USD 240. The holding period begins after acquisition and determines whether the later capital transaction is short term or long term.
Capital-asset sales generally use Form 8949 and Schedule D. The Form 8949 guide explains acquisition dates, proceeds, basis and digital-asset categories. Coins held as inventory or sold to customers in a business can follow a different character and form route. Do not combine reward income and later appreciation into one unexplained P&L figure.
Transfers between the miner's own wallets normally preserve basis and acquisition date rather than creating a new reward. Exchange deposits, wrappers and bridges must remain connected to the original lot. If history is missing, mark the disposal as needing basis reconciliation rather than replacing the original reward value with zero.
Mining, staking, forks and service payments are not interchangeable
Mining validates proof-of-work transactions. Staking rewards arise from proof-of-stake validation and have their own IRS authority, including Revenue Ruling 2023-14. A hard-fork asset, an airdrop, a referral bonus and compensation for services can all create income questions, but one rule should not be copied across every event. Map the source event before selecting an income category.
The US staking tax guide covers dominion and control for staking rewards. The broader US crypto tax guide explains disposals, 1099-DA reporting and the digital-asset question.
Year-end mining checklist and report workflow
- Export every pool statement and preserve payout terms before the account closes.
- Reconcile pool credits, fees and wallet receipts by asset and timestamp.
- Value each taxable receipt in USD with a documented source.
- Decide business versus nonbusiness treatment from the actual facts.
- Separate gross reward income, allowable expenses and asset basis.
- Carry acquisition date and basis through every own-wallet transfer.
- Report later disposals separately and review missing-basis lines.
- Reconcile Schedule C, Schedule 1, Schedule SE, Form 8949 and Schedule D as applicable.
CoinTaxReporting can map imported mining rewards, USD valuations and later disposals, but it cannot prove business status or an expense that is absent from the records. Use the US crypto tax calculator guide to understand which report totals are calculations and which inputs still require the full return.
Frequently asked questions
Do I owe US tax if I keep every mined coin?
Potentially yes. Notice 2014-21 includes the USD fair market value in gross income at receipt; a sale is not required for the initial income event.
Is every US miner subject to self-employment tax?
No. Notice 2014-21 applies self-employment tax where mining constitutes a trade or business and is not performed as an employee. Classification depends on the facts.
Can I deduct my entire electricity bill?
Not without evidence. A business miner should document actual mining consumption and allocate mixed personal and business use reasonably.
Is the basis of self-mined crypto zero?
Not when the reward's fair market value was included in income. That included amount generally becomes the starting basis for the later disposal calculation.
Does a mining-pool statement replace transaction records?
No. Keep the statement, payout terms, wallet receipt, USD price evidence and later transfer history so the reward and disposal ledgers reconcile.
