If you hold cryptocurrency, the most important thing to understand is how the IRS classifies it. The agency treats digital assets as property, not currency — which means the familiar rules for capital gains apply. The IRS keeps its official guidance on its Digital Assets page, and every Form 1040 now asks a yes/no question about digital-asset activity.
Because crypto is property, a taxable event happens whenever you dispose of it. That includes more than just cashing out to dollars:
The gain is the difference between your cost basis (what you paid, plus fees) and the value when you disposed of it. Hold for one year or less and it's a short-term gain taxed at ordinary income rates; hold longer than a year and it qualifies for generally lower long-term capital-gains rates — the same long-vs-short logic as stocks.
Some crypto arrives as ordinary income, taxed at its fair market value when you receive it: rewards from staking, mining, or interest, and crypto received as payment for work. That received value also becomes your cost basis for later capital-gains math.
Capital gains and losses from crypto are generally reported on Form 8949 and Schedule D; crypto income goes on the relevant income lines. Starting with the 2025 tax year, brokers and exchanges began issuing Form 1099-DA to report digital-asset proceeds — but the legal responsibility to report accurately is yours regardless of what forms you receive. Keep records of dates, amounts, cost basis, and the value at each transaction; crypto's many small transactions make record-keeping the hard part.
The bottom line: The IRS taxes crypto as property. Selling, swapping, or spending it can trigger capital gains, while staking and mining rewards count as ordinary income. Simply buying and holding isn't taxed. Track your cost basis and dates carefully — that's where most of the work is.
