The Tax Implications of Buying and Selling Cryptocurrency That Most Ignore

By Leo Sun – Apr 15, 2026 at 1:55PM ESTKey PointsSome investors think they only need to pay taxes when converting crypto to cash.However, every single transaction is actually a taxable event.Most crypto investors realize that converting a token to cash will trigger capital gains taxes on the trade. However, many investors overlook another major issue: every single sale, swap, or use of a cryptocurrency -- not just a conversion to U.S. dollars -- is a separate taxable event.

If you own Bitcoin (BTC 0.07%) and swap it to Ethereum (ETH +0.58%), you'll need to pay taxes on the profit you earned from the Bitcoin sale -- even if it was never converted to cash. Stablecoins like Tether (USDT 0.03%) and USD Coin (USDC +0.01%) might feel like cash because they're pegged to the U.S. dollar, but those trades are also taxable events.

For example, if you bought 0.1 Bitcoin for $3,000, its value appreciated to $7,400, and you used it to buy a new PC, you'd still need to pay a capital gains tax on the $4,400 gain even though you never converted your Bitcoin to cash. In other words, trading crypto too frequently can create some big headaches when you need to file your taxes. Like stocks, cryptocurrencies are subject to short- and long-term capital gains rates -- so any tokens sold in less than a year will be taxed at even higher rates.Read NextApr 15, 2026 •By Leo SunThe Biggest Risk in Crypto That Most Investors Completely IgnoreApr 15, 2026 •By Alex CarchidiIf You Own Cryptocurrency, You Need to Understand What's Happening With Oil Right NowApr 14, 2026 •By Leo SunHere's Why You Shouldn't Put More Than 5% of Your Portfolio in Any One CryptoApr 14, 2026 •By Anders BylundWhy Bitcoin Is Increasingly Being Treated Like Digital GoldApr 14, 2026 •By Leo SunIs Now Actually a Good Time to Buy Cryptocurrency?Apr 13, 2026 •By Neil PatelWhere Will Bitcoin Be in 10 Years?About the AuthorLeo Sun is a contributing Motley Fool stock market analyst who has worked with the company since 2013, covering technology, consumer goods, industrial, and financial sectors.
