Crypto miners need to get ready for tax season
A mining reward is taxable the day it lands in your wallet, before you sell anything. Here's how the IRS treats mining income in the US, how business and hobby filing differ, and what to line up before you file.
A block reward is income the moment you can move it, valued at what the coin was worth that day. That one rule catches more miners than anything else at filing time, because it creates a tax bill before you have sold a thing.
Whether you run a rack of ASICs or point spare GPU cycles at a pool on weekends, the reporting logic is the same. The size of your operation changes which forms you file and how much you owe, not whether the income counts.
How the IRS taxes what you mine
When you receive a block reward or a pool payout, you have ordinary income equal to the coin's fair market value at the time you gain control of it. Notice 2014-21 set this out for mining, and the IRS has held the same line for staking in later guidance. Log the date, the amount of coin, and the dollar value that day, because that value does two jobs.
It is income now, taxed at your ordinary rate for the year you received the coin. It also becomes your cost basis. When you later sell, swap, or spend that coin, your gain or loss is the sale price minus that basis, reported as a capital gain or loss on Form 8949 and Schedule D. Hold the coin more than a year before disposing of it and the gain is long-term, which is usually taxed at a lower rate.
Business or hobby, and why the label matters
The IRS looks at whether your mining is a trade or business or a hobby, and the answer changes your bill. If you mine with regularity and a profit motive, it is a business. You report the income and expenses on Schedule C, and the net profit is subject to self-employment tax on top of income tax. Once your net self-employment earnings reach $400 for the year, you are required to file a return for them.
If mining is a hobby, you still report the fair market value of what you mined as ordinary income, but you do not owe self-employment tax. The cost is that hobby miners generally cannot deduct their electricity, hardware, or other expenses. That gap is why a serious rig is almost always better off filing as a business.
A worked example
You mine 0.1 BTC on a day the coin is worth $60,000, so the reward is worth $6,000. You report $6,000 of ordinary income for that year, even if you never move the coin.
Months later you sell that 0.1 BTC for $7,000. Your basis is the $6,000 you already reported, so you have a $1,000 capital gain for the year of the sale. Sell at $5,000 instead and you report a $1,000 capital loss. The numbers are illustrative; use your own dated values.

File as a business and the cost of running it comes off your income. The common deductions for miners:
- Electricity used to run and cool the rigs, limited to the share tied to mining.
- Mining hardware, either depreciated over its useful life or expensed under Section 179 or bonus depreciation when it qualifies.
- Pool fees and network transaction costs.
- Rent or a home-office share for a dedicated space, plus repairs and the business portion of internet.
Keep the receipts and a plain log. If the IRS asks, an itemized power bill and a purchase record for your hardware carry more weight than any explanation after the fact.
What it costs to skip it
Unreported mining income is one of the easier things for the IRS to catch, and the penalties add up. File late and the failure-to-file penalty runs 5% of the unpaid tax per month, up to 25%. Pay late and the failure-to-pay penalty adds 0.5% per month, also up to 25%. If the IRS decides you substantially understated your tax, the accuracy-related penalty is another 20% of the underpayment, and interest runs on the balance until it is paid.
Enforcement has tightened since these letters first went out. Every Form 1040 asks a yes or no question about digital assets near the top, and answering it wrong while reporting nothing is its own problem. Starting with the 2025 tax year, exchanges file Form 1099-DA with you and the IRS for dispositions, so the agency increasingly sees your sales even when your return does not mention them. The gap between what a form shows and what you filed is what triggers a notice.
Before you file this year
- Pull your reward history. Export every payout with its date and the coin's value that day.
- Decide business or hobby honestly. Pick the right forms before you start entering numbers.
- Separate the two taxable events. Income when you received each coin, gain or loss when you sold it.
- Total your deductible costs if you are filing as a business, with records that back them.
- Answer the digital asset question on the 1040, and answer it truthfully.
Mining income is taxable and the rules are settled enough to follow. The expensive mistakes come from ignoring the income at receipt or losing track of basis, not from the mining itself.
