Bitcoin, ethereum, and other cryptocurrencies are rapidly evolving. Follow the latest developments from Yahoo Finance and others here.

You generally owe taxes when you sell cryptocurrency for more than you paid for it. This also applies when you exchange one digital asset for another. Converting bitcoin into ethereum, for example, isn’t “just a trade” in the eyes of the IRS. It’s a taxable event if the value changes.

Crypto taxes aren’t paid at the time of the transaction, but instead, they’re reported on your tax return for the year in which the transaction took place. So, if you sold crypto for a profit at any point during 2025, that activity is reported when you file your 2025 return in early 2026.

How much tax you pay depends on two main factors:

How long you held the asset before selling

Your overall taxable income and filing status

Hold it for less than a year, and you'll usually face higher rates. Hold it longer, and the rates tend to be lower.

This holding-period distinction matters more than most people realize. A few days can make a difference of as much as 17% or more — so timing matters.
