Earning crypto — by staking, mining, or receiving airdrops — feels very different from buying it. But for US tax purposes, the moment new coins land in your control, something important generally happens: you have income. Understanding how that income is measured, how it connects to your later sale of the same coins, and how to track it is essential, because reward income is one of the most commonly missed items on crypto tax returns.
The core principle: income when received, gain when sold
Almost everything in this guide follows from one two-step pattern. First, when you receive cryptocurrency as a reward — from staking, mining, an airdrop, or similar activity — the general IRS position is that you recognize ordinary income equal to the fair market value of the crypto in US dollars at the time you receive it. That income is taxed in the year of receipt, whether or not you sell the coins.
Second, that same fair market value becomes your cost basis in the coins you received. If you later sell, trade, or spend them, you have a capital gain or loss measured against that basis — the difference between your sale proceeds and the value you already paid income tax on. This prevents double taxation of the same economic gain while ensuring the income itself is taxed once.
A concrete example: you receive 0.5 ETH as a staking reward when ETH is worth $3,000, so you generally recognize $1,500 of ordinary income and your basis in that 0.5 ETH is $1,500. Months later you sell it for $1,800. You have a $300 capital gain ($1,800 minus $1,500). If instead you sell for $1,200, you have a $300 capital loss. The holding period for determining whether that capital gain or loss is short-term or long-term generally starts on the date you received the coins.
How staking rewards are generally taxed
Staking — locking up cryptocurrency to help secure a proof-of-stake network in exchange for rewards — produces a steady stream of small payouts. Under the general framework described above, each reward is ordinary income at its fair market value when you receive it. "Receive" generally means when you gain dominion and control over the coins — when they are credited to you and you can use them — not merely when the protocol accrues them in some pending state.
This framework was clarified by IRS guidance addressing staking rewards, which treats them as includible in gross income in the taxable year in which the taxpayer gains dominion and control. The exact mechanics can vary: on some networks rewards auto-compound into your staked balance, on others they sit claimable until you withdraw. Either way, the practical approach is to record income when the rewards are actually credited to your control, at that moment's USD value.
Note that guidance in this area has evolved over time — there have been notable developments, including litigation and updated IRS positions on staking rewards, and the details continue to be refined. Tax rules change, so verify current IRS guidance for the tax year in question rather than relying on older summaries.
How mining income is generally taxed
Mining — using computing power to validate transactions on a proof-of-work network in exchange for block rewards and fees — follows the same core pattern: the fair market value of the mined coins at the time of receipt is generally ordinary income. For miners, though, an additional question arises: is this a business or a hobby?
If your mining activity rises to the level of a trade or business — regular, profit-motivated, and substantial — the income is generally treated as self-employment income, which means it may be subject to self-employment tax in addition to income tax. On the other hand, business treatment also generally allows you to deduct ordinary and necessary business expenses: electricity, hardware depreciation, hosting fees, pool fees, and similar costs. The line between hobby and business depends on the facts and circumstances, and getting it wrong in either direction is costly.
Casual or small-scale mining that does not amount to a business is generally still taxable as ordinary income when the coins are received, but the expense deductions available to a business may not apply. Because the stakes — self-employment tax on one side, lost deductions on the other — are significant, anyone mining at meaningful scale should discuss the classification with a qualified tax professional rather than deciding it alone.
How airdrops and similar distributions are generally taxed
Airdrops — free distributions of tokens to wallet holders, often for marketing or governance purposes — are generally treated as ordinary income at fair market value when you receive them and gain dominion and control. The same principle extends to similar windfalls: hard fork coins credited to your wallet, referral bonuses paid in crypto, and promotional token distributions.
Airdrops create two practical headaches. First, valuation: many airdropped tokens are thinly traded at launch, so establishing a credible fair market value takes effort — check reputable price sources and document the figure you used. Second, spam: wallets routinely receive unsolicited dust or scam tokens. A sensible approach is to record legitimate airdrops you actually claim or control and can value, while being cautious about assigning income to worthless spam tokens you never asked for and cannot sell. When in doubt about a questionable distribution, document your reasoning and consider professional advice.
Remember the second half of the pattern: the income amount becomes your basis. If an airdropped token later moons and you sell, your gain is measured against the value you reported as income — not zero. People who forget to log the original airdrop often end up overstating their gain (or being unable to substantiate their basis) when they sell.
Liquidity mining, yield farming, and other DeFi rewards
Decentralized finance has invented many ways to earn yield: providing liquidity to automated market makers, lending assets on money markets, staking LP tokens, and collecting protocol incentive emissions. The labels vary, but the tax logic generally follows the same shape: when reward tokens are credited to your control, you typically have ordinary income at fair market value; when you later dispose of them, capital gain or loss applies.
DeFi complicates the details. Rewards may accrue continuously and only materialize when you "claim" them — the receipt question then turns on when you actually gained control. Some "rewards" are really just the appreciating value of a receipt token (like a lending pool's interest-bearing token), which may be better analyzed as a single position that grows in value rather than a series of income events. Governance tokens emitted as incentives, on the other hand, look much more like classic reward income. These distinctions are fact-specific and the guidance continues to develop, so complex DeFi positions deserve careful analysis — ideally with professional help — rather than a one-size-fits-all assumption.
What to record for every reward
Reward income is only as good as its records. For each batch of rewards — staking payouts, mining proceeds, airdrops, DeFi emissions — log:
- Date and time received. This sets both the income year and the start of your holding period for the later capital gain or loss calculation.
- Asset and quantity. Exactly what and how much, at full precision.
- Fair market value in USD at receipt. This is both your reported income and your future cost basis. Note the price source you used.
- Source. Which validator, pool, protocol, or airdrop the rewards came from, and the wallet address that received them.
- Transaction hash. For on-chain rewards, the hash is your proof of receipt and timing.
Because rewards arrive frequently, aggregation is your friend: many taxpayers and tools group small daily payouts into weekly or monthly totals. Whatever granularity you choose, keep the underlying detail available so the totals can be verified.
Hobby vs. business: why the distinction matters
Whether your earning activity is a hobby or a business affects two things: which taxes apply to the income and which expenses you can deduct. In general terms, business income from mining or validating may be subject to self-employment tax, while hobby income generally is not — but a business can generally deduct its ordinary and necessary expenses (equipment, electricity, fees), while hobby expense deductions are severely limited.
The IRS looks at the overall facts and circumstances — regularity, profit motive, time invested, and dependence on the income, among other factors — not at any single test. Running one GPU in a spare bedroom a few weekends a year looks different from operating a dedicated mining facility or a professional validator setup. There is no bright-line threshold, which is exactly why this classification is worth getting right with professional guidance if the amounts are meaningful.
Common tracking pitfalls
- Auto-compounding rewards. When staking rewards are automatically restaked, the income is still realized — "I never touched it" does not defer the tax. Make sure your tracker captures auto-compounded payouts as income events.
- Tiny, frequent payouts. Daily or per-block rewards create hundreds of micro income events. Import them via API or CSV rather than by hand, and aggregate sensibly.
- Claim transactions. On some protocols you must submit a transaction to claim accrued rewards. The gas fee for the claim is its own event (generally a disposition of whatever coin paid the fee), separate from the reward income.
- Rewards in illiquid tokens. If a reward token has no reliable market price at receipt, document your valuation method carefully — this is exactly the kind of number that gets questioned later.
- Mixing rewards with trading. Keep reward-receiving wallets distinct from active trading wallets where possible. Commingled lots make basis tracking far harder than it needs to be.
Where guidance has evolved
The tax treatment of staking rewards and similar crypto income has not stood still. Over the years, the IRS has issued notices and revenue rulings touching on virtual currency, courts have weighed in on specific disputes, and the agency's positions on issues like the timing of staking income have been refined. New reporting regimes for digital assets are also being phased in, which will change what information exchanges report to the IRS and to you.
The practical takeaway: treat anything you read — including this guide — as a snapshot, not a permanent rulebook. Before filing, verify the current IRS guidance for the tax year in question, and for anything beyond straightforward reward income, work with a qualified tax professional who follows this area. Tax rules change — verify current IRS guidance.
The rulings this guide rests on
The summaries above trace back to a short list of IRS documents, and for anything beyond a small portfolio they are worth reading directly. Notice 2014-21 is the foundation: it treats convertible virtual currency as property, and its questions and answers state that a miner includes the fair market value of mined coins in gross income — and, if the mining is a trade or business, that the income is subject to self-employment tax. Revenue Ruling 2019-24 covers hard forks and airdrops: a fork by itself creates no income, but new units received in an airdrop following a fork are ordinary income once you can transfer, sell, or exchange them. Revenue Ruling 2023-14 applies the same dominion-and-control test to staking: rewards are included in gross income for the taxable year in which you gain the ability to sell or otherwise dispose of them, valued at that time.
Two practical consequences follow. First, the taxable moment for all three income types in this guide is receipt with control, not the later sale — the sale is a second, separate event measured against the basis the first event created. Second, the record that proves the first event is a dated fair market value, which is why a same-day log — the income tracker exists for exactly this — is worth more than a year-end reconstruction from price charts.
