What is a taxable event in crypto?
A taxable event is a transaction that creates something to report for tax. In the US, the IRS treats crypto as property, so selling it, swapping it for another coin, spending it, or receiving it as pay or rewards is taxable; buying with dollars and simply holding is not.
What it means for you
In the US, every coin-to-coin swap and every purchase paid in crypto counts as a disposal with its own gain or loss, even when no dollars reach your bank. The IRS says moving coins between your own wallets is not taxable, even if you receive an information return for it. Your records of what you paid, and when, turn each event into a number.
A common mistake: “If I never cash out to dollars, I don't owe any tax.”
In fact: In the US, the IRS treats swapping one crypto for another, or paying for something with crypto, as a disposal that produces a capital gain or loss. Converting to dollars is only one of several taxable events.
How it works
The IRS treats digital assets as property, so general property-tax principles apply. Taxable events fall into two groups. Disposals — selling for dollars, exchanging for another digital asset, paying for goods or services, or paying a transaction fee in crypto — produce a capital gain or loss: the amount received minus your basis. Receipts — pay for services, mining, staking, and airdrops after a hard fork — produce ordinary income equal to fair market value when received. Buying with dollars, holding, a hard fork that brings no new coins, receiving a bona fide gift, and transfers between your own wallets are not taxable events.
An example
Say you bought a coin for $1,000 and later swap it for a different coin worth $1,500. In the US that swap is a disposal: you have a $500 capital gain, though no dollars changed hands, and your basis in the new coin is its $1,500 fair market value at the time of the exchange.
