Which crypto transactions are taxable events you must report
The IRS treats cryptocurrency as property, not currency, for federal tax purposes. This classification has consequences. Nearly every time you dispose of crypto, a taxable event occurs. Some transactions generate capital gains or losses. Others produce ordinary income. Knowing which is which matters at filing time.
Selling crypto for fiat
This is the most straightforward taxable event. You sell Bitcoin for US dollars. You sell Ether for euros. The difference between what you paid for the crypto and what you received when you sold it is a capital gain or loss. The IRS wants that reported on Schedule D and Form 8949.
Holding period determines the rate. Crypto held for one year or less is a short-term capital gain, taxed at your ordinary income rate. Crypto held longer than one year qualifies for long-term treatment, with lower rates.
Trading crypto for crypto
Many investors assume a trade is not a sale. The IRS disagrees. Swapping Bitcoin for Ethereum is a disposal of Bitcoin. You have sold one asset and bought another. The gain or loss is calculated in US dollars at the time of the trade. That gain is taxable that year, even if you never touched fiat.
This rule catches people off guard. A trade inside a wallet, a swap on a DEX, or an exchange between two tokens on the same platform - all are reportable events. Keep records of the fair market value of both assets at the moment of exchange.
Spending Crypto on Goods or Services
Buying a coffee with Bitcoin is a taxable event. Paying for a VPN with Monero is a taxable event. The IRS sees this as selling your crypto for something of value. The gain or loss is the difference between your cost basis and the fair market value of the goods or services received.
If you bought Bitcoin at $10,000 and spent it when it was worth $50,000, you have a $40,000 capital gain. The coffee itself is irrelevant. The property disposal triggered the tax.
Receiving Staking Rewards
Staking rewards are treated as ordinary income. When you receive a reward, its fair market value on the date you gain dominion and control over it is taxable income. This applies to proof-of-stake networks, delegated staking, and liquid staking tokens.
The timing can be tricky. Some protocols distribute rewards continuously. Others batch them. The IRS has not issued crystal-clear guidance on every staking model. The conservative approach: report the value when you can freely use or withdraw the reward.
Airdrops
Airdrops are generally ordinary income. When you receive tokens without paying for them, the fair market value at the time you gain control is taxable. That control point matters. If you cannot access the tokens until a later date, the income may be deferred until you can.
Some airdrops require action - connecting a wallet, claiming through a website, paying gas fees. Others deposit tokens directly. Each situation differs. The IRS has not issued exhaustive guidance, but the prevailing view among tax professionals is that airdrops are ordinary income at receipt.
Hard Forks
Hard forks create a separate question. When a blockchain splits, holders of the original chain may receive new tokens on the forked chain. The IRS addressed this in Revenue Ruling 2019-24. If you receive new crypto from a hard fork, you have ordinary income equal to the fair market value at the time you gain dominion and control.
That control point is important. You must be able to access, transfer, or sell the new tokens. If the forked chain is not immediately operational, no income is recognized until it is. Some hard forks never produce viable assets. No tax event occurs if you never gain control of anything of value.
Mining Income
Mining crypto generates ordinary income. The fair market value of the mined coins on the day you receive them is taxable income. This applies to both solo mining and pool mining. Mining expenses - electricity, hardware, cooling - may be deductible as business expenses or miscellaneous itemized deductions depending on whether mining is a hobby or a trade.
The distinction between hobby and business is factual. Hobby losses are not deductible. Business expenses can offset mining income. The IRS looks at intent, regularity, and profit motive.
Capital gains vs. ordinary income: the split
The taxable events above fall into two buckets. Selling, trading, and spending crypto generate capital gains or losses. Receiving staking rewards, airdrops, hard fork tokens, and mining income generate ordinary income.
The difference matters for tax rates. Ordinary income is taxed at your marginal rate, which can be as high as 37% plus the net investment income tax. Long-term capital gains have preferential rates - 0%, 15%, or 20% depending on your total income.
Losses offset gains. Short-term losses offset short-term gains first. Long-term losses offset long-term gains first. Any remaining loss reduces ordinary income up to $3,000 per year. Excess losses carry forward.
What the IRS says
IRS Notice 2014-21 established the basic framework: virtual currency is property. Revenue Ruling 2019-24 addressed hard forks. The IRS has also issued FAQs on virtual currency transactions. These documents provide the foundation, but they do not cover every edge case. Taxpayers must apply existing principles to new situations.
The IRS has not issued formal guidance on every DeFi protocol, NFT transaction, or layer-2 activity. The general principle holds: any disposition of property is a taxable event unless a specific exception applies.
What This Means
Every crypto transaction that involves a disposal must be tracked. Basis in, value at disposal out. The difference is either capital or ordinary. Record the date, the fair market value, and the counterparty if applicable.
There is no de minimis exemption for small crypto transactions in US federal tax law. A $2 airdrop is taxable. A $5 cup of coffee paid with Bitcoin is taxable. The IRS does not care about the amount - only that it happened.
Most exchanges and wallets do not provide tax-ready reports. You are responsible for assembling your own records. Software tools exist, but accuracy depends on the data you feed them. Mistakes in cost basis or timing can lead to underreporting.
The rules are clear enough for common transactions. The gray areas persist for newer activities. When in doubt, the conservative position - reporting income when you have control and gains when you dispose - is the safest path.
