Crypto Mining Taxes in 2026: Schedule C and the Double Hit

Bitcoin traded for about $77,300 on 2 September 2026, more than a third below its 2025 record high, and the machines kept running anyway. Every ten minutes or so, a miner or a pool somewhere on the network stitches together a valid block and collects the 3.125 BTC subsidy plus whatever fees the transactions inside it carried. To the protocol that reward is an incentive. To the Internal Revenue Service it is income, recognized the instant the coins land and valued in dollars on that exact date.

For ordinary investors, 2026 is the year the paperwork arrived: the first Form 1099-DA statements, the wallet-by-wallet basis rule, the digital-asset question sitting on top of Form 1040. Miners occupy a stricter corner of the code. Mining has had explicit IRS guidance since 2014, and it is the one crypto activity where a single block reward can trigger two separate tax events and, when you run it as a business, a self-employment tax stacked on top of the income tax. With the extended deadline for 2025 returns falling on 15 October and the first full year of restored 100 percent bonus depreciation now in effect, the cost of misclassifying a mining operation has rarely been higher.

What follows is a US federal tax map for individual miners and small operations: how a mined coin is taxed on the way in and on the way out, where the hobby-versus-business line falls and why it decides your bill, what a business can deduct, and how depreciation, entity choice, pool payouts, and estimated taxes fit together. It is general information, not tax advice; any operation with real revenue should hire a professional who has filed these returns before.

How the IRS Taxes a Mined Coin

The foundation is almost a decade old. IRS Notice 2014-21 established that virtual currency is treated as property, not currency, for federal tax purposes, and that a taxpayer who successfully mines it includes the fair market value of the coins in gross income as of the date of receipt. There is no election to defer, no de minimis threshold, and no exception for coins you plan to hold. If your rig earns 0.02 BTC in a block or a pool payout while Bitcoin trades at $80,000, you have $1,600 of ordinary income that day, whether or not you ever move or sell the coins.

That receipt value does two jobs at once. It is taxable income now, and it becomes your cost basis in the coins going forward. The distinction matters because Bitcoin does not sit still: the dollar figure you book at receipt is frozen in place, while the market keeps moving around it.

Every US taxpayer also has to answer the digital-asset question printed at the top of Form 1040, and receiving mining rewards is squarely a ‘Yes.’ The question is less a trap than a signpost; the IRS has said it uses the answer, together with third-party reporting, to flag returns where digital-asset income might be missing. For miners, whose income arrives on-chain rather than through a broker, an honest answer and the records to back it up are the whole game.

Two Taxable Events, One Block Reward

Because a mined coin is income at receipt and property afterward, disposing of it later is a second, separate taxable event. When you sell, spend, or swap the coin, you compare the proceeds to the basis you set at receipt and report a capital gain or loss. Hold the coin more than a year and any gain is long-term, taxed at 0, 15, or 20 percent depending on income; the 2026 breakpoints put the 0 percent rate up to $49,450 of taxable income for single filers and $98,900 for joint filers, with the 20 percent rate starting above $545,500 and $613,700 respectively. Sell inside a year and the gain is short-term, taxed at ordinary rates that reach 37 percent.

Miners sometimes call this double taxation, but that is not quite what happens. The receipt value is taxed once as ordinary income; only the change in value after receipt is taxed the second time, as a capital gain or loss. The same dollars are not taxed twice. The table below walks a single mined coin through both events.

The practical lesson is that the two events can point in opposite directions. In a falling market you can owe ordinary income tax on a coin mined at $90,000 and then, months later, book a capital loss when you finally sell it near $75,000. The income is locked in at the higher number; the loss is a separate line item that follows its own, more restrictive, rules.

Hobby or Business? The Line That Sets the Bill

Every downstream question, what you can deduct, which forms you file, whether you owe self-employment tax, hangs on one classification: is your mining a trade or business, or a hobby? The IRS decides this under Section 183, the activities-not-engaged-in-for-profit rules, using a nine-factor test drawn from the regulations: how businesslike your records are, your expertise, the time and effort you put in, your history of income or losses, your expectation that the assets will appreciate, and more, with no single factor controlling. There is a safe harbor: show a profit in three of five consecutive years and the IRS presumes you are in it for profit.

The stakes are lopsided. A business miner reports gross rewards on Schedule C, deducts ordinary and necessary expenses against them, and pays self-employment tax on the net. A hobby miner reports the same rewards as other income on Schedule 1 and deducts nothing. That last point is not a historical footnote: the 2017 tax law suspended the miscellaneous itemized deductions hobbyists once used to write off expenses, and the One Big Beautiful Bill Act signed in July 2025 made that suspension permanent. So a hobby miner in 2026 pays full ordinary tax on the gross value of every coin and cannot offset a single dollar of electricity or hardware. The comparison below makes the gap concrete.

Most people who buy a couple of machines and run them in a spare room assume hobby is the safe, low-key choice. For anyone spending real money on power and equipment, it is usually the expensive one.

Self-Employment Tax, the 15.3 Percent That Surprises People

The word business carries a cost that catches new miners off guard: self-employment tax. Where an investor pays only income tax on gains, a business miner also owes the 15.3 percent that funds Social Security and Medicare, the burden an employee normally splits with an employer, now carried alone. It breaks into 12.4 percent for Social Security, which in 2026 applies to net earnings up to a wage base of $184,500, and 2.9 percent for Medicare, which has no cap. High earners add a 0.9 percent Medicare surtax above $200,000 of earned income for singles and $250,000 for joint filers.

There is partial relief. You compute self-employment tax on 92.35 percent of net profit, and you deduct half of the resulting tax above the line, which softens the blow. Active mining income also sits outside the 3.8 percent net investment income tax, which targets passive and investment income rather than the proceeds of a trade you materially run. Even so, for a profitable home operation self-employment tax often exceeds the income tax on the same dollars, and it is the single biggest reason miners eventually study entity structures.

What a Business Miner Can Actually Deduct

Once you are a business, the ordinary-and-necessary standard opens up the expense side, and mining is unusually expense-heavy. The deductions that matter most, in rough order of size:

• Electricity, almost always the largest line. You deduct the business-use portion of the power drawn by the rigs and their cooling. Home miners should sub-meter or otherwise document the mining share rather than guessing, because a round-number estimate is exactly what an examiner questions.
• Hosting and colocation fees, fully deductible when you run machines in a third-party facility instead of at home.
• Hardware, deducted through depreciation rather than expensed all at once, covered in the next section.
• Repairs and maintenance, from replacement fans to swapped hashboards.
• Internet and networking costs allocable to the operation.
• Pool fees, the small cut a mining pool retains, which reduce your income or count as an expense depending on how the pool reports.
• Rent or a home-office deduction for space used regularly and exclusively for the business, plus interest on money borrowed to buy equipment.

The recurring theme is documentation. The deductions are generous, but each one assumes you can show the business purpose and the dollar amount. Miners who commingle personal and business power, hardware, and wallets hand the IRS the argument that the whole thing is a hobby.

Depreciation After the One Big Beautiful Bill

Mining hardware is the deduction most reshaped by recent law. ASIC miners are treated as five-year property under MACRS, the standard schedule for computers and similar gear, so absent any special provision you would write a machine off over roughly six calendar years. Two provisions let you accelerate that sharply, and 2026 is the first full year both run at full strength.

The bigger one is bonus depreciation. The 2017 tax law let businesses expense 100 percent of qualifying equipment in year one, then began phasing that down; it was set to fall to 40 percent in 2025 and disappear by 2027. The One Big Beautiful Bill Act reversed the phase-down and made 100 percent bonus depreciation permanent for property placed in service after 19 January 2025, covering new and used gear alike. In practice, a $90,000 ASIC energized in your 2026 business generates a $90,000 first-year deduction. The catch is the phrase placed in service. As Mike LaLuna, a CPA who prepares mining returns, put it in an industry guide, the deduction only works when the machine is ‘placed in service and operating in that same tax year,’ so a rig bought in December but not plugged in and hashing until January belongs to the later year.

Section 179 expensing is the other lever, and the OBBBA raised its cap to roughly $2.5 million with a phase-out beginning around $4 million. Section 179 comes first in the stacking order but is limited to taxable income and cannot create or deepen a loss; bonus depreciation is applied next, has no income limit, and can push a business into a net operating loss. For a heavily capitalized new operation, that ordering is the difference between a deduction you can use now and one you carry forward.

None of this is free money. Depreciation lowers your basis in the equipment, so when you eventually sell an ASIC, the gain up to the depreciation you claimed is recaptured as ordinary income under the Section 1245 rules, not taxed at friendlier capital-gains rates. Bonus depreciation front-loads the deduction; it does not erase the tax so much as move it in time.

One more limit decides whether a big first-year deduction is worth anything today. A depreciation-fueled loss offsets your other income, wages from a day job or a spouse’s salary, only if you materially participate in the mining business, meaning you are genuinely involved in running it. A hands-off investor who buys machines and lets a host do everything can find the loss treated as passive under the Section 469 rules, suspended until the activity throws off income or is sold. The line between an active operator and a passive check-writer is not cosmetic; it decides whether that $90,000 write-off shelters this year’s paycheck or sits idle.

Pools, Payouts, and When Income Is Recognized

Timing is where mining tax gets fiddly, because the income clock starts when you gain control of the coins, not when you decide to sell them. For staking the IRS made this explicit in Revenue Ruling 2023-14: rewards are income when the taxpayer obtains dominion and control, meaning the practical ability to sell or transfer them. Mining follows the same logic. A solo miner recognizes income when a block reward becomes spendable; a pool miner recognizes it as each payout reaches an address they control.

That makes the payout method matter. Under pay-per-share arrangements you receive steady, frequent credits whether or not your pool finds a block; under proportional or pay-per-last-N-shares schemes the timing and size swing with the pool’s luck. Either way, every credit is a separate income event valued at that moment’s price, which is why a busy pool miner can rack up thousands of micro-receipts in a year. The mechanics of how those payouts are calculated, and how solo and pooled mining differ, are worth understanding on their own; our explainer on how Bitcoin miners get paid walks through the schemes.

Do not expect a tax form to do the work for you. A US pool or service generally issues a 1099 only for payments of $600 or more from a single payer, and many miners either fall below that line or mine through pools with no US reporting duty at all. The missing form does not remove the income; it just means the recordkeeping is entirely on you. The crypto tax attorneys at Gordon Law make the same point in their mining guide: the sheer frequency of pool payouts, each needing a timestamped fair market value, is the real compliance burden, more than any single rule.

Fees, Runes, and a Changing Coinbase Transaction

The coins a miner earns are not only the block subsidy. Each block also sweeps up the transaction fees paid by everyone whose transactions it includes, and all of it, subsidy plus fees, is income at fair market value on receipt. Network-wide the subsidy is 3.125 BTC per block after the April 2024 halving, roughly 450 BTC a day across every miner, with fees layered on top.

Those fees are no longer a rounding error the way they once were. Bitcoin-native token systems, Ordinals inscriptions and the Runes fungible-token protocol, periodically flood the network with demand for block space, and during the sharpest of those episodes fees in individual blocks have briefly topped the 3.125 BTC subsidy itself. For a miner, a fee spike is simply more ordinary income, booked at whatever Bitcoin was worth in that block. The Runes market has cooled from its manic launch, but it still moves fee revenue in ways that show up on a return; we mapped where that market stands now in a separate piece. The tax treatment does not care whether a fee came from a routine payment or a frenzied token mint; a satoshi of fee income is taxed exactly like a satoshi of subsidy.

Entity Choice: Sole Proprietor, LLC, or S-Corp

A miner earning meaningful profit eventually meets the question every small business faces: what legal wrapper to use. By default, a solo miner is a sole proprietor filing Schedule C, simple but fully exposed to self-employment tax on every dollar of net profit. Forming an LLC changes the liability picture and the paperwork but not, by itself, the tax: a single-member LLC is still taxed as a sole proprietorship.

The structure people reach for to trim the self-employment bill is an S-corporation election. An S-corp pays the owner a reasonable salary, which bears payroll tax, and lets remaining profit pass through as a distribution that escapes the 15.3 percent self-employment charge. On a large enough profit, the saving outweighs the added payroll filings, state fees, and accounting cost; below some breakeven it does not, and an unreasonably low salary is itself an audit flag.

Sitting on top of all of this is the qualified business income deduction under Section 199A, which the OBBBA made permanent. It lets many pass-through owners deduct up to 20 percent of qualified business income, and because mining is not a specified service trade, miners can claim it even at higher incomes, subject to wage and property limits. Starting in 2026 the law also adds a minimum $400 deduction for anyone with at least $1,000 of active qualified business income. For a profitable miner, the QBI deduction can quietly become one of the most valuable lines on the return, and it is another benefit available to the business, not the hobby.

Estimated Taxes and the Volatility Trap

Mining income arrives with no withholding, so the IRS expects you to prepay it in quarterly installments using Form 1040-ES, with 2026 payments due on 15 April, 15 June, 15 September, and the following 15 January. Miss them and you owe an underpayment penalty even if you settle the full balance in April. The usual safe harbors apply: pay at least 90 percent of the current year’s tax, or 100 percent of last year’s (110 percent if your prior-year income was high), and the penalty disappears.

The harder problem is unique to being paid in a volatile asset. You are taxed on the fair market value of coins at receipt, but you pay in dollars, months later, out of coins whose price may have collapsed in the meantime. A miner who books income at $90,000 Bitcoin and still holds as it slides toward the $77,000 area seen in early September 2026 can face a tax bill larger than the current value of the coins that produced it. The disciplined answer is to sell a fixed slice of every reward immediately to cover the tax, treating the taxman as a silent partner in each block.

Some operators go further and hedge the revenue itself. Bitcoin-native instruments can lock in a price without surrendering custody of the coins; our look at discreet log contracts covers one such tool. Whatever the method, it beats discovering in April that the coins meant to pay January’s income tax are worth a fraction of the bill.

When Mined Coins Lose Value: Losses and Recapture

A down market turns the second taxable event into a planning tool. Sell coins for less than their receipt-date basis and you have a capital loss. Capital losses first offset capital gains; up to $3,000 of any excess can offset ordinary income each year, and the rest carries forward indefinitely. Because the IRS treats crypto as property rather than a security, the wash-sale rule that stops stock investors from selling at a loss and rebuying within 30 days does not currently apply, so a miner can realize a loss and re-establish the position without waiting, a gap Congress has repeatedly proposed to close but has not.

Losses on the hardware follow a different track. The bonus depreciation that wrote off your ASICs also drove their tax basis toward zero, so a later sale is mostly recapture: gain up to the depreciation claimed comes back as ordinary income, not capital gain. And if aggressive depreciation pushes the whole operation into a net operating loss, that NOL can carry forward to shelter future income, though it can offset only up to 80 percent of a later year’s taxable income. Two very different loss regimes, the property rules for the coins and the recapture rules for the machines, run side by side on the same return.

Staking as a Business, and the Jarrett Question

Proof-of-stake validators face a close cousin of the miner’s problem, and the same combined-income logic applies: run validation as a trade or business and the rewards are Schedule C income subject to self-employment tax; run it passively and they are ordinary income without it. Either way, Revenue Ruling 2023-14 says the reward is taxed when you gain dominion and control.

That timing is exactly what a Tennessee couple is still fighting. Joshua and Jessica Jarrett argue that tokens created by staking are new property, like a baker’s fresh loaf or a writer’s manuscript, and should not be income until sold. Their second lawsuit, filed in late 2024 in the Middle District of Tennessee, is set for trial on 29 September 2026, with the question of when, or whether, staking rewards are income squarely presented. A taxpayer win would not directly rewrite the mining rules, but it would unsettle the receipt-is-income principle that mining and staking both rest on, and it would hand miners an argument they do not have today. It is one of several 2026 flashpoints, from wash-sale and de minimis proposals to fresh IRS guidance, that could reshape digital-asset tax; we track the wider calendar in our regulatory countdown. For now the safe assumption remains the current one: income at receipt, full stop.

Recordkeeping, Audits, and Staying Out of Trouble

Everything above reduces to one operational demand: keep records a stranger could follow. For each reward that means the date and time, the amount of coin, its fair market value in dollars at that moment, and the wallet it landed in; for each disposal, the date, the proceeds, and the basis you are drawing down. Purpose-built crypto tax software can pull much of this from addresses and price feeds, but the miner owns the result.

The most expensive mistake is losing track of basis. A miner who reports the income at receipt but cannot later prove that receipt-date value can end up paying capital gains tax on the entire sale proceeds, as if the basis were zero, effectively paying tax twice on the same coins. That is not the law punishing miners; it is the record failing them. The fix is boring and non-negotiable: capture the fair market value at the moment of every reward, in a form you could hand to an examiner two years later.

The classification risk cuts both ways. Report business losses year after year and Section 183 invites an examiner to recharacterize the whole thing as a hobby, stripping the deductions retroactively; the defenses are the businesslike habits the nine factors reward, a separate bank account, a written plan, real books, and safe custody of the coins you hold, the kind of key-management discipline we cover in our guide to multisig best practices. Understate income, on the other hand, and you are exposed from the opposite side, since on-chain rewards are visible and the digital-asset question is now unavoidable.

It helps to remember how seriously the largest players take this. Publicly traded miners such as MARA, Riot, and CleanSpark disclose their bonus-depreciation benefits and deferred-tax positions in the reports they file with the Securities and Exchange Commission, precisely because depreciation timing and coin basis move real money. The individual running four machines in a garage is playing the same game by the same rules, just without a tax department. For anything past a trivial scale, the cost of a crypto-literate CPA is small next to the cost of getting the classification, the depreciation, or the estimated payments wrong.

Frequently Asked Questions

Do I owe taxes on crypto I mined but have not sold?

Yes. Under IRS Notice 2014-21, mined coins are ordinary income at their fair market value on the day you receive them, whether or not you ever sell. Selling later is a separate capital gain or loss measured against that receipt-date value, so holding is not a way to defer the income.

Is my mining a hobby or a business?

The IRS decides under Section 183 using a nine-factor profit-motive test that weighs businesslike records, time and effort, expertise, and your history of profit. A business files Schedule C, deducts expenses, and pays self-employment tax; a hobby reports income on Schedule 1 and, since the 2017 law’s deduction suspension was made permanent in 2025, can deduct nothing. For anyone spending real money on power and machines, business treatment is usually far better.

How much tax do Bitcoin miners pay?

A business miner pays ordinary income tax on the receipt value of rewards (rates up to 37 percent in 2026) plus 15.3 percent self-employment tax on net profit, then capital gains tax on any appreciation when the coins are later sold. Deductions for electricity, depreciation, and the 20 percent QBI deduction shrink the income-tax portion. A hobby miner pays ordinary income tax but no self-employment tax and gets no deductions.

Can I write off my mining rig and electricity?

Only if you mine as a business. Then electricity, hosting, repairs, and internet are deductible, and hardware is depreciated, with 100 percent bonus depreciation available in 2026 for equipment placed in service that year. Hobby miners cannot deduct any of it. Keep documentation, especially sub-metered power, because these deductions draw scrutiny.

Do mining pools send a 1099, and what if I do not get one?

A US pool generally issues a 1099 only for $600 or more from a single payer, and many miners either fall below that or use pools with no US reporting. The missing form does not remove the income; you still must report every payout at its fair market value on the date you received it, so the recordkeeping falls on you.
