NOT TAX ADVICE
This article is informational only. We are mining operators, not tax advisors. Tax treatment depends on your specific facts and circumstances. Consult a qualified CPA or tax attorney before filing. Specifically for crypto-native cases, look for credentials like AICPA Digital Asset Task Force membership or specialized crypto CPA practices. Filing deadline for 2025 returns is April 15, 2026.
Marcus Holbrook lives in Vancouver, Washington. He runs six Antminer S21 XPs hosted at MillionMiner Tier 2 ($0.075/kWh + $5/month standing fee per unit). His 2025 mining year was his first full year as an operator. The hardware ran reliably. The pool payouts came in clean. The hashrate did what the spreadsheet said it would do.
In late January 2026 he received a Form 1099-DA from Coinbase for the first time. The form showed gross proceeds of $48,000 from his digital asset transactions. The cost basis line was blank. His first reaction was that the IRS would assume he owed tax on $48,000 of capital gains, because that is exactly what the form looks like to anyone who has ever filed a 1099-B for stock sales.
The reality is more complicated and more favorable. Marcus’s mining ordinary income for 2025 was approximately $31,000 (the sum of fair market values at each block reward receipt). His capital gain on the eventual sale of those mined coins was approximately $4,200 (the difference between his $35,200 sale proceeds and his $31,000 cost basis). His actual total tax exposure for 2025 was roughly $35,200 of recognized income, split into two very different categories with very different tax treatments.
The 1099-DA tells the IRS what Marcus sold. It does not tell them what he mined, when he mined it, or what his cost basis is. For miners, the new 1099-DA form creates a documentation burden, not a free filing. This piece walks through the actual tax structure that applies to US Bitcoin miners in the 2026 filing season, the specific reconciliation steps required to handle a 1099-DA correctly, and the deductions available to operators who file as a business under Schedule C.

The fundamental mining tax structure: two taxable events, not one
The single most expensive mistake in mining taxation is treating block rewards as a one-time event. The IRS has been explicit since Notice 2014-21 that mined cryptocurrency triggers two separate tax events with two different forms and two different tax rates.

The fundamental mining tax structure: two taxable events, not one
The single most expensive mistake in mining taxation is treating block rewards as a one-time event. The IRS has been explicit since Notice 2014-21 that mined cryptocurrency triggers two separate tax events with two different forms and two different tax rates.
Event 1 is income recognition. The day a block reward (or pool payout) hits your wallet, you have realized ordinary income equal to the fair market value of the Bitcoin in US dollars at that moment. Per IRS Notice 2014-21: "When a taxpayer successfully ‘mines’ virtual currency, the fair market value of the virtual currency as of the date of receipt is includible in gross income." This applies whether or not you ever sell the coins.
Event 2 is capital gains recognition. When you later sell, exchange, or dispose of the mined Bitcoin, the difference between the sale price and your cost basis (the FMV from Event 1) is a capital gain or loss. Hold for under 365 days and the gain is short-term, taxed at ordinary income rates. Hold for over 365 days and the gain is long-term, taxed at the lower long-term capital gains rate (0%, 15%, or 20% depending on income bracket).
Worked example with concrete numbers. Suppose you receive 0.05 BTC as a pool payout on September 15, 2025, when BTC trades at $74,000. You have realized $3,700 of ordinary income that day, taxable on your 2025 return regardless of whether you ever touch the coins. Suppose you then sell that 0.05 BTC on May 19, 2026 (247 days later) at $78,500/BTC. You have realized a short-term capital gain of $225 on top of the $3,700 already taxed. Different forms (Schedule C for the income, Form 8949 plus Schedule D for the gain), different rates, and the cost basis at Event 2 is exactly the FMV that was already taxed at Event 1. No double taxation, but two distinct events.
Per TokenTax’s 2026 mining tax guide: "for tax purposes, US taxpayers earn ordinary income when you receive mining rewards. If you later sell, trade, or use the rewards, you will realize a capital gain or loss with the initial value acting as your cost basis." That last clause is the part most miners miss. Your cost basis on the eventual sale is the FMV you already paid ordinary income tax on, not zero.
THE DUAL-EVENT INSIGHT
Marcus mined 0.42 BTC across 2025 at varying daily prices. The sum of fair market values at each receipt totaled approximately $31,000 of ordinary income. He sold all of it in late 2025 for $35,200. His actual capital gain was $4,200, not $35,200. The 1099-DA he received from Coinbase shows $35,200 of gross proceeds. Filing without reconciliation would mean paying tax on $35,200 of phantom gains plus the $31,000 of ordinary income. Filing with reconciliation means paying tax on $31,000 + $4,200 = $35,200 of actual recognized income. Same total, very different distribution between schedules.
What Form 1099-DA actually reports (and what it misses)
Form 1099-DA is brand new for the 2025 tax year. The form was created under the Infrastructure Investment and Jobs Act of 2021 and finalized in regulations issued in 2024. Per the IRS Digital Assets official page: "Brokers must report gross proceeds for transactions effected on or after Jan. 1, 2025. Brokers must report basis on certain transactions effected on or after Jan. 1, 2026."
The first generation of these forms covers the 2025 tax year and was furnished to recipients by February 17, 2026. They report gross proceeds. They do not report cost basis. Cost basis reporting is phased in starting January 1, 2026, which means the second generation of forms (covering 2026 transactions, furnished in early 2027) will include basis information for some transactions but not all.
The covered exchanges include every major US-based centralized platform that holds custody of digital assets. Per CryptoTaxAudit’s 1099-DA technical guide: "Any centralized exchange with US ties has to generate these. Coinbase, Kraken, Gemini, Uphold, Robinhood, Fidelity, Franklin Templeton, Swan." International platforms like Binance International, Bybit, and KuCoin are not in scope, though US users of those platforms still owe tax on the underlying transactions.
What the form reports for miners specifically:
1. Gross proceeds: Total dollar value of digital asset sales executed on the broker's platform during the tax year. For miners, this is the total received from selling mined Bitcoin on the exchange.
2. Disposition dates: When each sale occurred. Used to determine short-term vs long-term holding period.
3. Wallet addresses: Per CryptoTaxAudit, "the 1099-DA includes wallet addresses for every transfer off the exchange." This creates an audit trail for how funds moved in and out.
4. Cost basis (2026 forward): Beginning with 2026 transactions reported in 2027, brokers will include cost basis where they have it. They will not have it for crypto transferred in from external wallets, which describes mined Bitcoin.
Event 2 is capital gains recognition. When you later sell, exchange, or dispose of the mined Bitcoin, the difference between the sale price and your cost basis (the FMV from Event 1) is a capital gain or loss. Hold for under 365 days and the gain is short-term, taxed at ordinary income rates. Hold for over 365 days and the gain is long-term, taxed at the lower long-term capital gains rate (0%, 15%, or 20% depending on income bracket).

The four reconciliation scenarios above cover the dominant patterns we see across our hosted operator base. The first scenario (mined coins transferred from pool wallet) is the most common: the broker shows full sale proceeds with no basis, the operator owes tax only on the gain over the FMV-at-receipt basis, and the gap between those two numbers can be 60-80 percent of the gross proceeds figure.
The second scenario is equally consequential in the opposite direction. Mining income earned in a pool wallet that you never moved to an exchange does not appear on any 1099-DA. The form has nothing to report because nothing was sold through the broker. But the income tax obligation under IRS Notice 2014-21 still applies. Mining ordinary income is owed whether or not the broker reports it. Per Camuso CPA’s 2026 1099-DA guide: "Do not prepare your tax return from the 1099-DA alone. You should reconcile the form to your wallet and exchange records, document your cost basis and accounting method, and retain support in anticipation of IRS matching and automated notices."
Hobby vs business: the classification that changes everything
The most consequential decision a US miner makes for tax purposes is whether to file as a business (Schedule C) or as a hobbyist (Schedule 1, line 8z, "Activity not engaged in for profit"). Same gross mining income, dramatically different effective tax rate.
Business filing (Schedule C)
Mining income is reported on Schedule C as gross receipts. All ordinary and necessary business expenses are fully deductible: electricity, hosting fees, hardware depreciation, repairs, internet, software, professional fees, home office (if applicable). Net profit flows to Form 1040 and is also subject to self-employment tax (15.3 percent on net earnings up to the Social Security wage base, 2.9 percent above).
The trade-off: deductions reduce both income tax and self-employment tax base. A miner with $50,000 of gross mining income and $35,000 of business expenses owes income tax and self-employment tax on $15,000 of net profit, not $50,000.
Hobby filing (Schedule 1)
Mining income is reported on Schedule 1 as miscellaneous income. Under the Tax Cuts and Jobs Act of 2017, miscellaneous itemized deductions subject to the 2 percent floor were eliminated through 2025. The practical result: hobby miners cannot deduct mining expenses against mining income. A hobby miner with $50,000 of gross mining income and $35,000 of actual expenses pays income tax on the full $50,000, not the $15,000 of net economic profit.
No self-employment tax applies to hobby income, which is the one offsetting advantage. But for any miner with meaningful operational expenses, the Schedule C path is dramatically more favorable.
How the IRS distinguishes hobby from business
There is no bright-line rule. The IRS uses a nine-factor test from Treasury Regulation 1.183-2 to determine whether an activity is engaged in for profit. The factors most relevant for miners:
1. Manner in which the taxpayer conducts the activity: Are you keeping books and records? Tracking pool payouts? Maintaining separate bank accounts and wallets for mining operations?
2. Time and effort expended: Active monitoring of fleet performance, troubleshooting hashboard failures, optimizing pool selection. Per TokenTax: "It depends on factors such as profit motive, scale, and how you conduct the activity."
3. History of income or losses: Mining at a loss is acceptable in early years if there is a clear path to profitability. Losing money for five consecutive years with no operational changes is a flag.
4. Amount of occasional profits: Even modest profits in some years support business intent.
5. Financial status of the taxpayer: A high-income W-2 earner running a mining operation that always loses money looks more like tax sheltering than business activity.
Practical guidance: any operator running 2+ machines with a documented business intent (LLC formation, separate bank account, professional bookkeeping, profit motive) almost always qualifies for Schedule C treatment. Single-machine home miners with no business infrastructure are in a gray zone where conservative practitioners file as hobby and aggressive practitioners file as business with documentation. The IRS has not historically pursued small-scale recreational miners aggressively, but the new 1099-DA reporting framework increases visibility across the board.
Schedule C deductions: what miners can actually claim
Business filing unlocks every deduction below. The single biggest change for the 2025 tax year is the One Big Beautiful Bill Act (signed July 4, 2025), which permanently restored 100 percent bonus depreciation for equipment placed in service after January 19, 2025. This is a meaningful policy shift that significantly changes after-tax mining economics.

The single biggest change for the 2025 tax year is the One Big Beautiful Bill Act (signed July 4, 2025), which permanently restored 100 percent bonus depreciation for equipment placed in service after January 19, 2025. This is a meaningful policy shift that significantly changes after-tax mining economics.
Hardware depreciation: Section 179 vs 100% bonus depreciation
Two competing methods exist for deducting the cost of mining hardware. Both are aggressive front-loading mechanisms designed to incentivize equipment investment.
Per IRS Publication 946 (2025): "For tax years beginning in 2025, the maximum section 179 expense deduction is $2,500,000. This limit is reduced by the amount by which the cost of section 179 property placed in service during the tax year exceeds $4,000,000." For 2026, the limit rises to $2,560,000 with a $4,090,000 phase-out threshold. Both figures will be inflation-adjusted annually going forward under OBBBA provisions.
100 percent bonus depreciation under IRC §168(k) is the OBBBA-restored alternative. Per BitFuFu’s OBBBA analysis: "the Act permanently reinstated 100% bonus depreciation. In layman’s terms, it lets businesses and mining business owners immediately deduct 100% of the entire cost of ‘eligible business assets’ in the year they are placed in service. ASIC miners qualify."
Three structural differences between the two methods: 1. Section 179 cannot create a net operating loss. It is limited to your taxable business income. If you spent $500,000 on hardware but only have $300,000 of business income, Section 179 caps your year-1 deduction at $300,000, with the remaining $200,000 carried forward. 2. 100% bonus depreciation can create a net operating loss. Per Terra Hosting’s OBBBA scenario analysis: "There is no income limit, you can deduct the $500,000 in year 1 and reduce your taxable income to -$200,000 as a net operating loss. This method saves you $72,000 in taxes while creating a net operating loss that can be carried forward." 3. Section 179 has a phase-out at $4,000,000 of equipment purchases. 100 percent bonus depreciation has no monetary cap.
Practical guidance: for purchases under $500,000 with sufficient income to absorb the deduction, Section 179 is straightforward. For purchases over $500,000, mixed-source income, or operators planning to carry losses forward, 100 percent bonus depreciation is structurally better. Both methods can be combined within the same tax year for different equipment lots, with Section 179 elected on specific assets and bonus depreciation applied to the rest.
Electricity, hosting, and the home office trap For self-hosted operators, electricity is the largest deductible operating expense. The math is simple but the documentation matters: only the electricity directly attributable to mining is deductible, not your full residential bill. Sub-metering the mining circuit is the cleanest way to document this. A standalone meter on the dedicated mining circuit produces an audit-proof number.
For hosted operators, the entire hosting invoice is deductible as a business expense on Schedule C, line 27a (Other expenses). This includes the kWh charges, standing fees, setup fees, and any incidental hosting-related costs. No allocation work required because the hosting provider has already separated mining electricity from any other use. Per our hosting cost breakdown, the four-tier MillionMiner pricing structure produces invoiced totals that flow directly into the Schedule C deduction without further calculation.
The home office deduction is the most-claimed and most-frequently-mishandled mining-related deduction. The qualifying standard is "regular and exclusive use" of a portion of your home for the mining business. A garage that contains your miners and your car does not qualify (not exclusive). A bedroom that contains your miners and your guest bed does not qualify (not exclusive). A dedicated outbuilding used only for mining qualifies. A dedicated room with no other use qualifies.
For operators who do qualify, the simplified method ($5/sq ft up to 300 sq ft, capped at $1,500) produces a small but real deduction with minimal documentation. The actual expense method (allocating a percentage of home utilities, mortgage interest, insurance, and depreciation based on the square footage of the dedicated space) can produce a larger deduction but requires detailed records. For most home miners, the simplified method is the right answer because the actual expense method creates record-keeping overhead disproportionate to the deduction size.
Five common mistakes US miners make on their first return
Mistake 1: Treating the 1099-DA as a complete record of taxable activity
The 1099-DA reports digital asset sales executed on a US broker's platform. It does not report mining ordinary income that never touched the broker. A miner who only sold a portion of their mined Bitcoin during the year owes ordinary income tax on every block reward received during the year, including the unsold portion still sitting in pool wallets or self-custody. The 1099-DA covers maybe 20-40 percent of the actual reportable activity for a typical hosted operator.
Mistake 2: Reporting gross proceeds as capital gains
Filing the 1099-DA gross proceeds figure directly as a capital gain (because the cost basis line was blank) results in massive over-reporting. The fix is the cost basis adjustment on Form 8949 Box A or Box C: enter the broker-reported proceeds, then enter the actual cost basis (sum of FMV at each block reward receipt for the lots sold), and the difference is the actual gain or loss. Tax software will handle this if the basis is provided correctly. The IRS does not assume basis is zero just because the broker did not report it.
Mistake 3: Skipping Schedule C and forgetting self-employment tax
Filing mining income as hobby income on Schedule 1 saves the 15.3 percent self-employment tax up front but blocks all expense deductions. For any operator with meaningful electricity or hosting costs, the math favors Schedule C even after self-employment tax. A worked example: $50,000 gross mining income, $35,000 hosting and operational expenses. Schedule C: $15,000 net x 15.3% SE tax = $2,295, plus income tax on $15,000 (assume 22% bracket) = $3,300. Total tax: $5,595. Schedule 1 hobby: no SE tax, but income tax on full $50,000 = $11,000. Schedule C saves $5,405 on the same economic outcome.
Mistake 4: Mishandling wallet-to-wallet transfers
Transferring Bitcoin between wallets you control is not a taxable event. Moving 0.5 BTC from your pool wallet to a hardware wallet, then to a Coinbase hot wallet, then selling on Coinbase produces one taxable sale event, not three. The 1099-DA shows the destination wallet addresses, which can look alarming if the miner does not document that those wallets all belong to them. The fix is record-keeping: maintain a wallet inventory with creation dates, the source of funds for each, and the original FMV at receipt. Match every wallet on the form to a documented source.
Mistake 5: Missing the wallet-by-wallet basis allocation requirement Per IRS Revenue Procedure 2024-28, effective January 1, 2025, taxpayers must allocate cost basis on a wallet-by-wallet basis (or account-by-account basis), not on a universal basis across all wallets. Most miners pre-2025 used universal cost basis tracking by default. The transition to wallet-by-wallet basis allocation is required and creates a one-time reallocation event for any miner holding pre-2025 lots. Tax software like Koinly, CoinTracker, and TokenTax handles the transition automatically if configured correctly. Manual filers need to document the allocation method and the snapshot at January 1, 2025.
When to hire a crypto CPA (and what to look for)
The DIY threshold for mining taxes is lower than most operators expect. Single-machine home miners with one exchange and one wallet can usually handle their own returns with TurboTax or similar consumer software. Beyond that, the complexity climbs fast.
Specific scenarios where a specialized crypto CPA is worth the fee: 1. Multi-exchange operations with self-custody intermediate steps. The lot tracking complexity scales nonlinearly with exchange count. Three exchanges plus a hardware wallet plus a pool wallet creates several thousand potential lot-matching scenarios per year for a moderately active operator. 2. First year of business filing after prior hobby filing. The transition involves recharacterizing prior years' income, which has implications for Schedule SE retroactive obligations, Section 179 elections, and depreciation start-date conventions. 3. Mining operations across multiple states or countries. State income tax treatment of digital assets varies. Foreign exchange usage may trigger FBAR or Form 8938 reporting requirements with $10,000+ penalties for non-compliance. 4. Operations exceeding $400,000 of gross proceeds. Per CryptoTaxAudit, "high-volume traders with Total Positive Income over $400,000 are priority IRS audit targets." TPI is calculated before subtracting costs or losses. For miners selling actively, gross proceeds can hit this threshold even at modest profitability. 5. Pre-purchase tax structuring decisions. Decisions about LLC formation, S-corp election, Section 179 vs bonus depreciation strategy, and entity-level vs personal-level deduction routing are difficult to undo after the fact. A consultation before deploying capital costs less than the structural mistakes it prevents.
What to look for when hiring:
> Active CPA license in your state or attorney with tax LLM credential.
> Specific crypto experience demonstrated through case studies or publications, not just general CPA credentials.

Frequently asked questions
Do I have to pay tax on Bitcoin I mined but never sold?
Yes. Per IRS Notice 2014-21, mining income is recognized at fair market value on the day of receipt, regardless of whether you sell. If you mined 0.1 BTC throughout 2025 at varying prices, you owe ordinary income tax on the sum of those FMVs even if you held everything in self-custody. The capital gains event (Event 2) only happens when you eventually dispose of the coins. The income event (Event 1) happens at the moment of receipt.
I received a Form 1099-DA showing $48,000 in proceeds. Do I owe tax on $48,000?
Almost certainly not. The 1099-DA shows gross proceeds (sales) without cost basis. Your actual taxable gain is the proceeds minus your cost basis, which for mined coins equals the fair market value at the time of mining (Event 1). Marcus's example: $48,000 in proceeds against $31,000 in cost basis equals approximately $17,000 of capital gain plus the $31,000 of ordinary income from Event 1. The total taxable income is approximately $48,000, but it splits into two categories with two different rates, not one large capital gain.
Should I file my mining as a hobby or a business?
For most miners with operational expenses, business filing under Schedule C produces a substantially lower total tax liability even after factoring in self-employment tax. The hobby vs business distinction depends on the IRS's nine-factor test from Treasury Regulation 1.183-2, with primary weight given to manner of operation (record-keeping, separate accounts), profit motive (clear path to profitability), and time/effort expended. Operators running 2+ machines with documented business intent almost always qualify for Schedule C. Single-machine home miners are in a gray zone where the choice depends on operational documentation.
What is the Section 179 deduction limit for mining hardware in 2025 and 2026?
Per IRS Publication 946, the 2025 Section 179 deduction limit is $2,500,000 with a phase-out beginning at $4,000,000 of qualifying equipment purchases. For 2026, the limit rises to $2,560,000 with a $4,090,000 phase-out threshold. Both figures will be inflation-adjusted annually under OBBBA provisions. Section 179 cannot create a net operating loss; it is limited to your taxable business income. For deductions exceeding business income, 100 percent bonus depreciation under OBBBA is the structurally better alternative.
What changed with the One Big Beautiful Bill Act (OBBBA) for mining taxes?
OBBBA was signed July 4, 2025. The most significant mining-relevant provision is the permanent restoration of 100 percent bonus depreciation for equipment placed in service after January 19, 2025. ASIC miners qualify. There is no monetary cap on the deduction. The deduction can create a net operating loss that carries forward to offset future income. This is a structural improvement over both the prior bonus depreciation phase-out schedule and the limitations of Section 179. For mid-scale operators deploying $500,000+ in hardware, OBBBA provisions can shift after-tax economics by 20-30 percent.
Are hosting fees fully deductible?
Yes, for business filers under Schedule C. The entire hosting invoice (kWh charges, standing fees, setup fees, repair charges) is deductible as an ordinary and necessary business expense on Schedule C line 27a. Hobby filers cannot deduct hosting fees against mining income. This is one of the cleanest reasons to qualify for business filing: a hosted operator paying $7,000/year in hosting fees recovers approximately $1,540 in tax savings (at 22 percent bracket) under Schedule C versus $0 under hobby treatment.
Do I need to report wallet-to-wallet transfers between my own wallets?
No. Transferring Bitcoin between wallets you control is not a taxable event. Moving coins from a pool wallet to a hardware wallet to an exchange hot wallet does not trigger income or capital gains. However, Form 1099-DA shows the destination wallet addresses for transfers off the broker's platform, which can create reconciliation work. Maintain a wallet inventory documenting which wallets you control, when they were created, and the source of funds for each. This documentation prevents IRS automated matching from assuming transfers are dispositions.
What happens if I do not report mining income that does not appear on a 1099-DA?
You owe the tax regardless. Per IRS Notice 2014-21, mining income is taxable whether or not a third party reports it. The IRS has multiple cross-reference mechanisms for identifying unreported crypto income, including chain analysis, John Doe summonses to exchanges, and pattern matching across reported transactions. Per Camuso CPA: "Crypto exchanges may report taxpayer-linked activity, and blockchain data is public, making wallet flows traceable. Assume your activity is discoverable and maintain thorough records." The penalties for unreported income include the unpaid tax, interest, accuracy-related penalties (20 percent), and in extreme cases fraud penalties (75 percent) or criminal referral.
Is the wash sale rule applicable to Bitcoin?
Currently, no. The wash sale rule (IRC §1091) applies to "stocks and securities" and the IRS has not issued guidance treating digital assets as securities for this purpose. This means crypto investors and miners can sell at a loss to harvest tax losses and immediately repurchase the same asset without the 30-day wash sale period that applies to stock losses. This treatment may change. Multiple legislative proposals have included extending wash sale rules to digital assets. Confirm current treatment with your CPA before relying on this for material tax planning.
When are 2025 mining tax returns due?
April 15, 2026, for individual returns (Form 1040 with Schedule C). Extensions to October 15, 2026, are available by filing Form 4868 before the April 15 deadline, but extensions cover only the filing date, not the payment deadline. Tax owed must still be paid by April 15 to avoid late-payment penalties. Quarterly estimated tax payments are required for self-employed filers expecting to owe $1,000 or more, with payments due April 15, June 15, September 15, and January 15 of the following year.
The bigger picture
Marcus filed his 2025 return through a crypto CPA in Austin who specializes in mining operations. Total fee: $2,400, including the basis reconciliation, the wallet inventory documentation, and the Schedule C preparation with Section 179 election on the six S21 XPs. His final tax bill on $35,200 of total recognized income (split between $31,000 ordinary and $4,200 short-term gain) came in at approximately $9,800 federal plus $1,800 Washington state and local. Without the CPA, his initial draft return prepared from the 1099-DA alone would have generated approximately $14,000 of federal tax on phantom gains, plus the $9,800 he actually owed. The CPA fee paid for itself roughly twice over.
That outcome is replicable. The 1099-DA reconciliation is mechanical once the framework is clear. The dual-event structure is the single most important concept to internalize: every block reward triggers ordinary income at receipt, every disposal triggers capital gains separately, and the cost basis at disposal equals the FMV already taxed at receipt. From there, the work is documentation: pool payout records, wallet inventory, hosting invoices, hardware purchase receipts and placed-in-service dates. The 100 percent bonus depreciation provision under OBBBA changes the after-tax economics of new hardware purchases meaningfully and is the single most operator-favorable tax development of the past five years.
For operators currently shopping hardware with the 2025 tax year still open for placed-in-service decisions through year-end, our best Bitcoin miners 2026 ranking covers the current flagship lineup with pre-tax economics. Combine that pre-tax math with 100 percent bonus depreciation under OBBBA to model the actual after-tax deployment economics. For pure operational questions about hosting versus self-hosting, our hosting cost breakdown and home mining versus hosted mining comparison cover the relevant trade-offs at the four MillionMiner pricing tiers.
Two weeks remain to the April 15 filing deadline as of publication. If you have not yet pulled your 1099-DA, requested your pool payout history, or compiled your wallet inventory, the time to start is now. If you have done the documentation work but are unsure about the dual-event reconciliation, the Schedule C versus Schedule 1 decision, or the Section 179 versus bonus depreciation election, the cost of a one-hour consultation with a specialized crypto CPA is roughly the cost of two months of hosted electricity for a single S21 Pro. The arithmetic favors the consultation.
NOT TAX ADVICE
Reminder: this article is informational only. Tax treatment depends on your specific facts and circumstances, your state of residence, your filing status, and the specific composition of your mining operations. Consult a qualified CPA or tax attorney before filing. The information here was current as of April 30, 2026. IRS guidance evolves; always verify current rules at irs.gov before relying on any specific provision discussed in this piece. We are mining operators, not tax advisors.
Per IRS Publication 946 (2025): "For tax years beginning in 2025, the maximum section 179 expense deduction is $2,500,000. This limit is reduced by the amount by which the cost of section 179 property placed in service during the tax year exceeds $4,000,000." For 2026, the limit rises to $2,560,000 with a $4,090,000 phase-out threshold. Both figures will be inflation-adjusted annually going forward under OBBBA provisions.
100 percent bonus depreciation under IRC §168(k) is the OBBBA-restored alternative. Per BitFuFu’s OBBBA analysis: "the Act permanently reinstated 100% bonus depreciation. In layman’s terms, it lets businesses and mining business owners immediately deduct 100% of the entire cost of ‘eligible business assets’ in the year they are placed in service. ASIC miners qualify."
Three structural differences between the two methods: 1. Section 179 cannot create a net operating loss. It is limited to your taxable business income. If you spent $500,000 on hardware but only have $300,000 of business income, Section 179 caps your year-1 deduction at $300,000, with the remaining $200,000 carried forward. 2. 100% bonus depreciation can create a net operating loss. Per Terra Hosting’s OBBBA scenario analysis: "There is no income limit, you can deduct the $500,000 in year 1 and reduce your taxable income to -$200,000 as a net operating loss. This method saves you $72,000 in taxes while creating a net operating loss that can be carried forward." 3. Section 179 has a phase-out at $4,000,000 of equipment purchases. 100 percent bonus depreciation has no monetary cap.
Practical guidance: for purchases under $500,000 with sufficient income to absorb the deduction, Section 179 is straightforward. For purchases over $500,000, mixed-source income, or operators planning to carry losses forward, 100 percent bonus depreciation is structurally better. Both methods can be combined within the same tax year for different equipment lots, with Section 179 elected on specific assets and bonus depreciation applied to the rest.
Electricity, hosting, and the home office trap For self-hosted operators, electricity is the largest deductible operating expense. The math is simple but the documentation matters: only the electricity directly attributable to mining is deductible, not your full residential bill. Sub-metering the mining circuit is the cleanest way to document this. A standalone meter on the dedicated mining circuit produces an audit-proof number.
For hosted operators, the entire hosting invoice is deductible as a business expense on Schedule C, line 27a (Other expenses). This includes the kWh charges, standing fees, setup fees, and any incidental hosting-related costs. No allocation work required because the hosting provider has already separated mining electricity from any other use. Per our hosting cost breakdown, the four-tier MillionMiner pricing structure produces invoiced totals that flow directly into the Schedule C deduction without further calculation.
The home office deduction is the most-claimed and most-frequently-mishandled mining-related deduction. The qualifying standard is "regular and exclusive use" of a portion of your home for the mining business. A garage that contains your miners and your car does not qualify (not exclusive). A bedroom that contains your miners and your guest bed does not qualify (not exclusive). A dedicated outbuilding used only for mining qualifies. A dedicated room with no other use qualifies.
For operators who do qualify, the simplified method ($5/sq ft up to 300 sq ft, capped at $1,500) produces a small but real deduction with minimal documentation. The actual expense method (allocating a percentage of home utilities, mortgage interest, insurance, and depreciation based on the square footage of the dedicated space) can produce a larger deduction but requires detailed records. For most home miners, the simplified method is the right answer because the actual expense method creates record-keeping overhead disproportionate to the deduction size.
Five common mistakes US miners make on their first return
Mistake 1: Treating the 1099-DA as a complete record of taxable activity
The 1099-DA reports digital asset sales executed on a US broker's platform. It does not report mining ordinary income that never touched the broker. A miner who only sold a portion of their mined Bitcoin during the year owes ordinary income tax on every block reward received during the year, including the unsold portion still sitting in pool wallets or self-custody. The 1099-DA covers maybe 20-40 percent of the actual reportable activity for a typical hosted operator.
Mistake 2: Reporting gross proceeds as capital gains
Filing the 1099-DA gross proceeds figure directly as a capital gain (because the cost basis line was blank) results in massive over-reporting. The fix is the cost basis adjustment on Form 8949 Box A or Box C: enter the broker-reported proceeds, then enter the actual cost basis (sum of FMV at each block reward receipt for the lots sold), and the difference is the actual gain or loss. Tax software will handle this if the basis is provided correctly. The IRS does not assume basis is zero just because the broker did not report it.
Mistake 3: Skipping Schedule C and forgetting self-employment tax
Filing mining income as hobby income on Schedule 1 saves the 15.3 percent self-employment tax up front but blocks all expense deductions. For any operator with meaningful electricity or hosting costs, the math favors Schedule C even after self-employment tax. A worked example: $50,000 gross mining income, $35,000 hosting and operational expenses. Schedule C: $15,000 net x 15.3% SE tax = $2,295, plus income tax on $15,000 (assume 22% bracket) = $3,300. Total tax: $5,595. Schedule 1 hobby: no SE tax, but income tax on full $50,000 = $11,000. Schedule C saves $5,405 on the same economic outcome.
Mistake 4: Mishandling wallet-to-wallet transfers
Transferring Bitcoin between wallets you control is not a taxable event. Moving 0.5 BTC from your pool wallet to a hardware wallet, then to a Coinbase hot wallet, then selling on Coinbase produces one taxable sale event, not three. The 1099-DA shows the destination wallet addresses, which can look alarming if the miner does not document that those wallets all belong to them. The fix is record-keeping: maintain a wallet inventory with creation dates, the source of funds for each, and the original FMV at receipt. Match every wallet on the form to a documented source.
Mistake 5: Missing the wallet-by-wallet basis allocation requirement Per IRS Revenue Procedure 2024-28, effective January 1, 2025, taxpayers must allocate cost basis on a wallet-by-wallet basis (or account-by-account basis), not on a universal basis across all wallets. Most miners pre-2025 used universal cost basis tracking by default. The transition to wallet-by-wallet basis allocation is required and creates a one-time reallocation event for any miner holding pre-2025 lots. Tax software like Koinly, CoinTracker, and TokenTax handles the transition automatically if configured correctly. Manual filers need to document the allocation method and the snapshot at January 1, 2025.
When to hire a crypto CPA (and what to look for)
The DIY threshold for mining taxes is lower than most operators expect. Single-machine home miners with one exchange and one wallet can usually handle their own returns with TurboTax or similar consumer software. Beyond that, the complexity climbs fast.
Specific scenarios where a specialized crypto CPA is worth the fee: 1. Multi-exchange operations with self-custody intermediate steps. The lot tracking complexity scales nonlinearly with exchange count. Three exchanges plus a hardware wallet plus a pool wallet creates several thousand potential lot-matching scenarios per year for a moderately active operator. 2. First year of business filing after prior hobby filing. The transition involves recharacterizing prior years' income, which has implications for Schedule SE retroactive obligations, Section 179 elections, and depreciation start-date conventions. 3. Mining operations across multiple states or countries. State income tax treatment of digital assets varies. Foreign exchange usage may trigger FBAR or Form 8938 reporting requirements with $10,000+ penalties for non-compliance. 4. Operations exceeding $400,000 of gross proceeds. Per CryptoTaxAudit, "high-volume traders with Total Positive Income over $400,000 are priority IRS audit targets." TPI is calculated before subtracting costs or losses. For miners selling actively, gross proceeds can hit this threshold even at modest profitability. 5. Pre-purchase tax structuring decisions. Decisions about LLC formation, S-corp election, Section 179 vs bonus depreciation strategy, and entity-level vs personal-level deduction routing are difficult to undo after the fact. A consultation before deploying capital costs less than the structural mistakes it prevents.
What to look for when hiring:
> Active CPA license in your state or attorney with tax LLM credential.
> Specific crypto experience demonstrated through case studies or publications, not just general CPA credentials.
> AICPA Digital Asset Task Force membership, Forbes "Best-In-State CPA" recognition, Tax Notes Federal contributor status, or similar markers of practice depth.
> Familiarity with mining-specific issues: pool payout reconciliation, wallet-by-wallet basis allocation under Rev. Proc. 2024-28, hosting fee deduction handling, hardware depreciation strategy.
> Transparent fee structure. Crypto CPAs typically charge $1,500-$5,000 for a return depending on complexity. Hourly consultation rates run $300-$600.
Avoid: generic CPAs claiming crypto experience without specific case examples, tax preparers who suggest reporting only the 1099-DA without reconciliation, anyone promising specific tax outcomes before reviewing your records.

Almost certainly not. The 1099-DA shows gross proceeds (sales) without cost basis. Your actual taxable gain is the proceeds minus your cost basis, which for mined coins equals the fair market value at the time of mining (Event 1). Marcus's example: $48,000 in proceeds against $31,000 in cost basis equals approximately $17,000 of capital gain plus the $31,000 of ordinary income from Event 1. The total taxable income is approximately $48,000, but it splits into two categories with two different rates, not one large capital gain.
Should I file my mining as a hobby or a business?
For most miners with operational expenses, business filing under Schedule C produces a substantially lower total tax liability even after factoring in self-employment tax. The hobby vs business distinction depends on the IRS's nine-factor test from Treasury Regulation 1.183-2, with primary weight given to manner of operation (record-keeping, separate accounts), profit motive (clear path to profitability), and time/effort expended.

Per IRS Publication 946, the 2025 Section 179 deduction limit is $2,500,000 with a phase-out beginning at $4,000,000 of qualifying equipment purchases. For 2026, the limit rises to $2,560,000 with a $4,090,000 phase-out threshold. Both figures will be inflation-adjusted annually under OBBBA provisions.

Are hosting fees fully deductible?
Yes, for business filers under Schedule C. The entire hosting invoice (kWh charges, standing fees, setup fees, repair charges) is deductible as an ordinary and necessary business expense on Schedule C line 27a. Hobby filers cannot deduct hosting fees against mining income. This is one of the cleanest reasons to qualify for business filing: a hosted operator paying $7,000/year in hosting fees recovers approximately $1,540 in tax savings (at 22 percent bracket) under Schedule C versus $0 under hobby treatment.
Do I need to report wallet-to-wallet transfers between my own wallets?
No. Transferring Bitcoin between wallets you control is not a taxable event. Moving coins from a pool wallet to a hardware wallet to an exchange hot wallet does not trigger income or capital gains. However, Form 1099-DA shows the destination wallet addresses for transfers off the broker's platform, which can create reconciliation work.
