A 2024 survey covered miners running about half of Bitcoin’s global computing power, with U.S.-based firms accounting for 75.4% of the power those miners reported using. But crypto mining in the U.S. is not limited to large-scale facilities. Individuals also mine from home or join mining pools to earn crypto rewards, making the tax treatment relevant to miners of all sizes.
So, how is crypto mining taxed in the U.S.?
The answer depends on how you mine, when you receive a reward, and what you do with it afterwards. The Internal Revenue Service (IRS) generally treats mining rewards as taxable income when received, while selling or disposing of those rewards later can create a separate capital gains tax (CGT) event. Hence, this article explains every aspect of crypto mining taxation in the U.S.
Key Takeaways:
- Mining rewards are ordinary income at their fair market value (FMV) when you gain control of them.
- The IRS treats cryptocurrency as property, not currency, under U.S. federal tax law
- Selling mined crypto triggers a separate capital gains tax event
- Business miners can deduct expenses such as electricity and equipment; hobby miners cannot
- Self-employment tax applies when mining qualifies as a trade or business
How Does the IRS Classify Crypto Mining?
The IRS classifies both the crypto you receive and the activity through which you earn it. These classifications determine how your mining income is taxed and which tax rules apply to your activity.
Does the IRS Consider Mining a Business or a Hobby?
Your facts decide whether mining is a hobby or a business. The IRS weighs factors like how regularly you mine and whether you run it for profit. That classification controls your deductions, your forms, and whether you owe self-employment tax.
Factor | Hobby Mining | Business Mining |
Frequency | Occasional, irregular | Regular and continuous |
Profit Motive | No structured profit intent | Clear profit motive |
Expense Deductions | Not eligible | Ordinary and necessary expenses deductible |
Tax Form | ||
Self-Employment Tax | Does not apply | Applies on net earnings |
Equipment Depreciation | Not allowed | Allowed |
Electricity Deduction | Not allowed | Allowed |
How Is Crypto Mining Taxed in the U.S.?
Crypto mining creates two distinct tax events: one when you receive your rewards and another when you sell or dispose of them. Each is governed by different tax rules and reported on different forms.
Earning Mining Rewards As Hobby
Each mining reward is ordinary income equal to its FMV in U.S. dollars. You recognize that income when you gain dominion and control, meaning you can sell, exchange, or otherwise dispose of the coins. The rule applies to hobby and business miners alike. That income is taxed at your regular federal rate, alongside your wages and other earnings. For tax year 2026, those rates range from 10% to 37% under the IRS 2026 income tax brackets.
Earning Mining Rewards As Business Income
If your mining counts as a trade or business, your net mining earnings are subject to self-employment tax. Net earnings are your mining income minus allowable business expenses. You owe this tax on top of regular income tax once net earnings reach $400 for the year.
The self-employment tax rate is 15.3%, made up of two parts:
- 12.4% for Social Security, up to the annual Social Security wage base
- 2.9% for Medicare, with no earnings cap
Unlike employees, who split these taxes with their employers, self-employed miners generally pay both portions. You can then deduct the employer-equivalent portion when calculating your adjusted gross income. Higher earners may also face an additional 0.9% Medicare tax on earnings above $200,000 for single filers or $250,000 for married couples filing jointly.
Disposing Of Mined Crypto
Selling, trading, or spending mined crypto creates a capital gain or loss. Your cost basis is the FMV you reported as income. Your holding period starts the day after you receive the coins.
Under the IRS capital gains rules, your rate depends on how long you held the coins. Coins held one year or less produce short-term gains, taxed at ordinary rates of 10% to 37%. Coins held more than one year qualify for long-term rates of 0%, 15%, or 20%.
How to Calculate Crypto Mining Taxes?
Calculating mining taxes accurately requires tracking every reward individually from the moment it’s received. Here’s how to work through the process step by step.
Step 1: Record the Date and FMV of Each Mining Reward
Log the date, time, and U.S. dollar value of every mining reward. For rewards received outside an exchange, the IRS accepts values from a blockchain explorer. The explorer must track worldwide price indices at an exact date and time. Keep these logs with your mining pool statements.
Step 2: Calculate Your Ordinary Income
Multiply the number of coins received by their FMV at the date and time of receipt.
Step 3: Establish Your Cost Basis
The FMV you reported as ordinary income for each reward automatically becomes your cost basis for that batch of tokens. This figure is what you’ll subtract from your future sale price to determine your capital gain or loss.
Step 4: Calculate Capital Gains or Losses on Disposal
When you sell or trade mined crypto, subtract the cost basis from the sale proceeds. If the result is positive, you have a capital gain. If negative, you have a capital loss that can be used to offset other gains.
What Crypto Mining Expenses Can You Deduct?
Only business miners can deduct mining expenses. Hobby miners must report all rewards as income but cannot deduct any costs. Here are the expenses that can be deducted:
Electricity Costs
Electricity is often a miner’s largest cost. Business miners can deduct the share of electricity used for mining. If you mine at home, separate mining power from household use. A dedicated meter or a documented usage calculation supports the deduction.
Mining Equipment and Depreciation
Mining hardware includes application-specific integrated circuit (ASIC) miners and graphics processing units (GPUs). Business miners generally recover hardware costs through depreciation over several years. Section 179 expense or bonus depreciation may allow a larger first-year deduction. Check current limits in IRS Publication 946 before filing.
Rented Space and Home Office Deduction
Rent for a dedicated space used for mining can generally be deducted as a business expense. If you mine from home, you may also qualify for the home office deduction, provided the space is used regularly and exclusively for mining. A space used for both mining and personal activities generally does not qualify.
Repairs, Maintenance, and Other Business Costs
Ongoing costs to keep mining equipment running, repairs, replacement parts, and routine maintenance are deductible for business miners. Additional business costs, such as accounting fees, software subscriptions, and internet services directly tied to the mining operation, may also qualify.
How to Report Crypto Mining on Your Tax Return?
Accurate reporting starts with having the right records and knowing which IRS forms apply to your situation. Below are the steps to report crypto mining on taxes in the U.S.
Step 1: Gather All Mining Transaction Records
Collect wallet records, mining pool payout statements, and any Form 1099 you received. You must report all mining income, even if no form arrives. Cross-check each form against your own reward log before filing.
Step 2: Report Mining Income on the Correct Schedule
Hobby miners report rewards on Schedule 1 (Form 1040), line 8v, “Digital assets received as ordinary income not reported elsewhere.” Business miners report income and expenses on Schedule C. Net profit flows to Schedule 1, line 3, and to Schedule SE for self-employment tax.
Step 3: Report Capital Gains on Form 8949
For every batch of mined crypto you sold or traded during the year, calculate the capital gain or loss using the established cost basis and enter each transaction on Form 8949. Identify each as short-term or long-term based on your holding period.
Step 4: Summarize Capital Gains on Schedule D
Once Form 8949 is complete, transfer the short-term and long-term totals to Schedule D. This is where the IRS sees your overall capital gains picture for the year, combining mining disposals with any other crypto transactions.
Step 5: Answer the Digital Asset Question
Check “Yes” to the digital asset question at the top of Form 1040. The IRS lists receiving new digital assets from mining as a “Yes” trigger. This applies even if you never sold a mined coin.
Step 6: Pay Estimated Tax During the Year
No tax is withheld from mining rewards. If you expect to owe at least $1,000 when you file, you must make estimated tax payments. For tax year 2026, payments are due April 15, June 15, and September 15, 2026, and January 15, 2027. Pay any remaining balance by the filing deadline.
How KoinX Helps You Report Crypto Mining Taxes Accurately?
Every mining reward needs a timestamp, a U.S. dollar value, and a cost basis. Frequent pool payouts can add up to hundreds of entries a year. KoinX automates the entire process, from pulling in your transaction data to generating the reports you need to file.
Auto-Import Mining Rewards From All Platforms
Connect your exchanges, wallets, and mining pools through KoinX integrations. Each mining reward imports with its original date and time, so you don’t re-enter payouts by hand. Solo miners can add wallet addresses to capture rewards paid directly by the network. Your full reward history then sits in one place.
Automatically Calculate Mining Income and Cost Basis
Each reward is valued in U.S. dollars at the date and time you received it. That value is your ordinary income for the reward. It is also recorded as the cost basis for that batch of coins. When you later sell, your gain or loss is measured from this starting value.
Generate IRS-Compliant Tax Reports in Minutes
The Form 8949 Report lists each mined coin you sold. The IRS Schedule D Report summarizes the totals. Gains follow the accounting method you choose. Options are first-in, first-out (FIFO), last-in, first-out (LIFO), or highest-in, first-out (HIFO).
Mining tax reporting doesn’t have to be a headache. KoinX handles the data, the calculations, and the IRS forms automatically, so nothing falls through the cracks. Get started to build your mining income log before you file.
Conclusion
Crypto mining creates real tax obligations at every stage, from the moment you receive a reward to the time you experience gain or loss when you sell it. Your hobby or business classification decides whether you can deduct costs and owe self-employment tax.
Start with a reward log. Record each payout’s date, time, and FMV, and keep your pool statements. Business miners should also track electricity, hardware purchases, and estimated tax payments through the year. Import your mining rewards here to build that log from your wallet and pool data.
Frequently Asked Questions
Is Crypto Mining Double-Taxed?
No. Mining creates two separate tax events, and neither taxes the same dollars twice. You pay ordinary income tax on a reward’s FMV when you gain control of it. That value becomes your cost basis. When you sell, capital gains tax applies only to the increase above that basis. A $1,000 reward sold for $1,200 creates only a $200 gain.
How Do I Value Mining Rewards If My Coin Isn't on a Major Exchange?
Use the coin’s value at the date and time the reward is recorded on the blockchain. The IRS accepts values from a blockchain explorer that tracks worldwide price indices. If you use another source, you must show that it accurately reflects FMV. Record the source you used for every reward.
Do I Have to Report Mining Income If I Didn't Get a Form 1099?
Yes. You must report income from all taxable crypto transactions, whether or not you receive a Form 1099. Most solo miners never receive one, and many pools don’t issue them either. Your own reward log is the record you report from, so keep it complete.
When Does the Holding Period Start for Mined Crypto?
Your holding period starts the day after you receive the mined coins. For example, coins received on March 10, 2026 must be held until at least March 11, 2027 for a long-term gain. Each reward batch has its own holding period, so track them separately.
