Mining cryptocurrency can feel like free money landing in your wallet, but the Internal Revenue Service (IRS) sees it very differently. Mined coins are taxable, and the way you report them depends heavily on one question: are you mining as a hobby or as a trade or business? That single distinction changes which forms you file, whether you can deduct your costs, and whether you owe self-employment tax. This guide walks through the rules for a general U.S. audience.
The controlling guidance is IRS Notice 2014-21. It states that when a taxpayer successfully mines virtual currency, the fair market value (FMV) of the coins as of the date of receipt is included in gross income. In other words, the moment a block reward or mining payout hits your wallet, you have ordinary income equal to what those coins were worth, in U.S. dollars, at that time. This is true whether or not you ever sell them.
That FMV at receipt does double duty: it is your income figure, and it also becomes your cost basis in the coins going forward. Establishing that basis correctly is essential, because it determines your gain or loss later.
Mining triggers tax in two separate stages over the life of the coins:
This two-layer structure is why careful mining records matter so much. If you forget the basis you established at receipt, you risk paying tax twice on the same value.
Whether you mine as a hobby or as a business does not change the fact that the coins are income. What it changes is how you report that income and what you can deduct against it.
Hobby miners generally report the income as other income, and under current rules they typically cannot deduct their mining expenses. Electricity, hardware, and pool fees are simply nondeductible personal costs in a hobby. The full FMV of the rewards is taxed with nothing to offset it.
Business miners — those carrying on mining as a trade or business — report income and expenses on Schedule C. They can deduct ordinary and necessary business expenses, which can dramatically reduce taxable profit. The trade-off is that net profit is subject to self-employment tax, reported on Schedule SE, on top of regular income tax.
| Factor | Hobby mining | Business mining |
|---|---|---|
| Is the reward taxable income? | Yes — FMV at receipt (Notice 2014-21) | Yes — FMV at receipt (Notice 2014-21) |
| Where income is reported | Generally Schedule 1 (other income) | Schedule C (business income) |
| Deduct expenses (electricity, etc.)? | Generally no | Yes — ordinary & necessary business expenses |
| Hardware depreciation | Not available | Yes — Section 179 / bonus depreciation |
| Home office deduction | Not available | Possible where eligible |
| Self-employment tax | No | Yes — on net profit (Schedule SE) |
| Quarterly estimated taxes | May apply | Commonly applies |
There is no single bright-line rule. The IRS evaluates whether an activity is a trade or business carried on for profit using a multi-factor, facts-and-circumstances test — the same general hobby-vs-business factors the agency applies to any activity. Factors it weighs include:
No single factor is decisive. A large operation with dedicated rigs, a profit motive, and detailed records points toward a business; an occasional GPU running in a spare room points toward a hobby.
If you qualify as a business, the deductions can be substantial. Common categories include:
Mining hardware is a capital asset, so its cost is generally recovered through depreciation rather than deducted all at once by default. However, Section 179 depreciation and bonus depreciation may let a business expense much or all of qualifying equipment in the year it is placed in service, subject to the applicable limits. Because depreciation rules are intricate and change with tax legislation, this is an area where professional guidance pays off.
The hardest part of mining taxes is documenting the FMV of each reward at the moment you received it. Build a habit of recording, for every payout:
Mining pools may produce frequent small payouts, so this can be hundreds of entries a year. Crypto-tax software or a disciplined spreadsheet keyed to your wallet history is the practical way to stay accurate.
Mining income usually has no withholding, so the IRS generally expects you to pay tax as you earn it through estimated quarterly tax payments. Business miners in particular often need to send quarterly payments covering both income tax and self-employment tax to avoid underpayment penalties. Setting aside a portion of each payout for taxes can prevent an unpleasant surprise at filing time.
Staking and mining are often discussed together, but they rest on slightly different guidance. For staking rewards, the IRS issued Revenue Ruling 2023-14, which holds that staking rewards are included in gross income at their fair market value when the taxpayer gains dominion and control over them. The income-at-receipt principle is similar to mining, but staking does not involve the same hardware-heavy expense and depreciation profile, and the business-vs-hobby analysis can play out differently. Our DeFi and staking taxes guide covers Rev. Rul. 2023-14 in more depth.
Business mining can produce a net loss, especially in the early years or when coin prices fall below operating costs. Whether and how such losses can offset other income, carry to other years, or be limited depends on rules around at-risk amounts, passive activity, hobby-loss limits, and net operating losses. These interactions are complex and fact-specific.
Because mining touches ordinary income, capital gains, self-employment tax, depreciation elections, and estimated payments all at once, it is one of the areas where working with a licensed CPA or tax professional who understands digital assets is genuinely valuable. The right structure and elections can change your bill significantly — and the records you keep all year are what make those choices possible.
Suppose over the course of a month you receive mining rewards totaling 0.5 BTC. On the various days you received them, the rewards had a combined FMV of $30,000.
The same coins were taxed twice across their life — once as income when mined, and again as a capital gain when sold — but only on the new value gained at each stage, never on the same dollars twice.
A reminder on authority: the rules summarized here trace back to IRS guidance, including Notice 2014-21, the use of Schedule C and Schedule SE for self-employment tax, Section 179 depreciation, the IRS hobby-vs-business factors, and Revenue Ruling 2023-14 for staking. Tax law changes, and the IRS continues to update its digital-asset guidance. Always confirm current rules with the IRS directly or a qualified CPA before filing.
Yes. Under IRS Notice 2014-21, mined coins are ordinary income at their fair market value on the date you receive them, whether or not you ever sell. Selling later is a separate, second taxable event that produces a capital gain or loss against the basis you established at receipt.
It depends on whether you mine as a business or a hobby. Business miners reporting on Schedule C can generally deduct ordinary and necessary expenses such as electricity, pool fees, and hardware depreciation (potentially via Section 179). Hobby miners generally cannot deduct these costs under current rules.
If your mining rises to the level of a trade or business, the net profit reported on Schedule C is generally subject to self-employment tax via Schedule SE, in addition to regular income tax. Hobby mining is not subject to self-employment tax, but it also cannot deduct expenses.
Both are income at fair market value when received. Mining is addressed by Notice 2014-21, while staking rewards are addressed by Revenue Ruling 2023-14, which taxes them when you gain dominion and control. Mining also tends to involve significant hardware costs and depreciation that staking usually does not.
