How Cryptocurrency Is Taxed in the US
Selling, trading, spending, staking, airdrops — some crypto activity is taxable and some is not. This guide sorts out which moves trigger tax under IRS rules, and which leave your return untouched.
Many people first hear that cryptocurrency is taxed "like stocks" and stop there. That summary is useful but incomplete. In the United States, the Internal Revenue Service (IRS) has its own framework for digital assets, and it determines which of your actions create a tax event, how gains are measured, and how the resulting numbers are reported. This guide explains that framework in plain language so you can understand what the rules ask of you before you trade, spend, or earn crypto.
One important note up front: cryptocurrency tax rules are not static. The IRS has issued guidance over the years and continues to refine reporting requirements, particularly for brokers and exchanges. Treat this guide as education, not a substitute for professional advice, and check current IRS publications whenever you prepare a return.
Crypto is property, not currency
The foundation of US crypto taxation is IRS Notice 2014-21, published in 2014. In that notice, the IRS announced that for federal tax purposes, virtual currency is treated as property, not as currency. That single classification decision shapes nearly everything else: it means the general tax rules for property transactions — buying, selling, exchanging, and receiving property — apply to cryptocurrency activity.
Why does this matter? If crypto were treated as a foreign currency, different rules would apply to gains from currency movements. As property, each disposition of cryptocurrency — selling it, trading it for another coin, or spending it — is treated like selling a piece of property. You compare what you received (the proceeds) to what you originally paid or otherwise acquired it for (your cost basis), and the difference is generally a capital gain or a capital loss.
The property classification also explains why volatility matters so much for taxes. When a currency you use every day moves slightly in value, nobody expects you to track gains. But as property, each sale of crypto is a taxable event measured against the price at which you acquired it. A coin that doubles between purchase and sale produces a taxable gain when you sell, even if you immediately roll the money into another investment.
What property treatment means in practice
Thinking of crypto as property clarifies a few everyday situations. First, holding crypto has no tax consequence by itself. Just as owning a house that rises in value does not create income until you sell, an unrealized gain in your crypto portfolio is not taxed. Tax generally enters the picture only when you dispose of the asset or receive new crypto as income.
Second, every disposition needs two numbers: the amount realized (what you got) and your adjusted basis (roughly, what you paid plus certain adjustments). The difference between them is your gain or loss on that transaction. Because crypto prices move constantly, your gain depends on the exact value at the moment of the transaction, which is why the IRS cares about the fair market value of the cryptocurrency at the time you receive or dispose of it.
Third, property rules come with record-keeping expectations. For each transaction, you should know the date you acquired the crypto, the date you disposed of it, the amount of crypto involved, the fair market value at both moments, and any fees. Exchanges provide trade histories, but on-chain transfers and decentralized trades are your responsibility to document.
Taxable events: when a tax bill can arise
Under the property framework, a taxable event generally occurs when you dispose of cryptocurrency for something of value or receive cryptocurrency as compensation. The three most common taxable events for everyday users are selling crypto for dollars, trading one cryptocurrency for another, and spending crypto on goods or services.
Selling crypto for US dollars
This is the most straightforward taxable event. If you bought Bitcoin at one price and later sold it for dollars at a higher price, the difference is generally a capital gain. If you sold at a lower price, it is generally a capital loss, which can offset gains under the usual capital loss rules. The gain or loss is measured at the time of the sale using the fair market value in US dollars.
Crypto-to-crypto trades
This one surprises many people: trading one cryptocurrency directly for another — for example, swapping Ethereum for Solana on a decentralized exchange — is generally a taxable disposition of the coin you gave up. The IRS treats it as if you sold the first coin for its dollar value and immediately bought the second. Even though no dollars touched your hands, the tax system sees a sale and measures your gain or loss against your basis in the coin you traded away. Frequent traders can accumulate dozens or hundreds of these taxable events in a single year.
Spending crypto on goods or services
Paying for something with crypto is also generally a taxable event. If you buy a laptop with Bitcoin that has appreciated since you acquired it, the purchase is treated as a disposition: you sold the Bitcoin at its current value and used the proceeds to buy the laptop. The gain on the Bitcoin is taxable even though you never converted it to dollars yourself. This is why paying with highly appreciated crypto can be an expensive choice compared with paying in dollars.
Non-taxable events: what usually doesn't trigger tax
Not everything you do with crypto creates a tax event. Understanding the non-taxable category is just as important, because it tells you which activities you can do freely and which ones require tracking.
- Buying crypto with US dollars. Purchasing cryptocurrency with dollars is generally not taxable — you are simply converting one form of property into another at cost. Your cost basis becomes what you paid, including fees. No gain or loss is recognized at purchase.
- Holding crypto. Watching your portfolio rise or fall creates no tax consequence while you hold. Unrealized gains and losses are not reported.
- Transferring crypto between your own wallets. Moving coins from an exchange to your own hardware wallet, or between wallets you control, is generally not a disposition. You still own the same asset; it just sits somewhere new. Keep records of these transfers anyway, because they help establish an unbroken chain of ownership for your cost basis.
- Donating crypto to a qualified charity. Donations of appreciated crypto to eligible charities can have favorable treatment under the charitable contribution rules, though the specifics depend on how long you held the asset and the charity's status. This is an area where professional guidance pays off.
A word of caution: wrapping, bridging, or converting tokens in decentralized finance can be ambiguous. Some of these actions may look like mere transfers but could be treated as taxable exchanges depending on the mechanics. Tax rules change — verify current IRS guidance before assuming a DeFi transaction is non-taxable.
Cost basis and fair market value
Cost basis is the anchor of the entire system. Your basis in a cryptocurrency is generally what you paid for it — the purchase price plus transaction fees. When you later sell, trade, or spend that crypto, your taxable gain equals the amount realized minus your basis. Get the basis wrong and everything downstream, from your gain calculation to your reported totals, is wrong too.
Fair market value (FMV) is the dollar value of the cryptocurrency at a specific moment. The IRS generally looks to the value on an exchange at the date and time of the transaction. For income events — receiving crypto as pay, mining rewards, or staking rewards — the FMV at the time of receipt generally becomes both the amount of ordinary income you report and your cost basis going forward. That basis then matters when you later sell the coins.
Fees deserve attention because they are easy to overlook. Trading fees, network (gas) fees, and exchange spreads are real costs of acquiring or disposing of crypto, and they generally adjust your basis or proceeds. Over hundreds of transactions, unrecorded fees can noticeably distort your reported gains, so a good tracking habit includes fees from the start.
Receiving crypto as payment or income
Not all crypto tax events are capital gains. When you receive cryptocurrency as payment for work, as mining rewards, as staking rewards, or from an airdrop, the IRS generally treats that as ordinary income, similar to wages or self-employment income. The amount of income is generally the fair market value of the crypto on the date you received it.
This creates a two-step tax story that trips people up. Step one: you report ordinary income equal to the value of the crypto when received. Step two: that same value becomes your cost basis. If the coins later appreciate and you sell them, the additional increase is generally a capital gain. You are not taxed twice on the same dollars — the income step sets your basis so the capital-gain step only measures the change after receipt.
Employment and freelance situations add their own layer. Crypto paid as wages is generally subject to the same reporting and withholding concepts as dollar wages, and crypto received for freelance work is generally self-employment income. The details depend on your employment classification, so keep clear records of what you received, when, and in what capacity.
Rules keep evolving
The framework described here — property treatment, taxable dispositions, basis, and income recognition — has been stable since IRS Notice 2014-21, but the surrounding rules keep moving. Information reporting by brokers and exchanges is being phased in, the IRS continues to update its digital asset guidance, and questions around staking, lending, and newer DeFi mechanics are still being clarified.
The practical takeaway is to build habits that survive rule changes: track every acquisition and disposition with dates and dollar values, keep exchange statements and wallet records, and separate income events from capital transactions in your records. Good records make any reporting regime easier, current or future. And because tax rules change — verify current IRS guidance, and consult a qualified tax professional before filing.
Edge cases the IRS has answered directly
Receiving a genuine gift. If you receive cryptocurrency as a bona fide gift, you do not recognize income when you receive it. Your basis is generally the donor’s basis, carried over — which means the donor’s records become part of your tax file, and the gain, when you eventually sell, is measured from what the donor paid. The IRS covers gifts in its virtual currency FAQ; a gift with no record of the donor’s basis is a common and avoidable problem.
Coins from a hard fork you never asked for. A hard fork alone is not income. If new units are airdropped to you after a fork and you can transfer or sell them, that receipt is ordinary income at fair market value — the rule in Revenue Ruling 2019-24. If the units sit somewhere you cannot access, the income event waits until you actually gain control of them.
Earning crypto for work. Cryptocurrency paid for services is income at its fair market value on the day you receive it — wages for an employee, self-employment income for an independent contractor — and that value becomes your basis. This is the original rule in Notice 2014-21, and it applies however informal the arrangement feels.
