Do You Pay Tax on Crypto Losses? (2026 US Guide)

Short answer: no, you don't pay tax on a loss - a loss isn't income. But that's not the whole story, because a properly reported loss is one of the few tax breaks a losing year hands you. Here's how to actually use it. General information, not tax advice.

A loss is a tool, not just a wound

When you sell crypto for less than you paid, you realize a capital loss. That loss offsets your capital gains dollar-for-dollar. If your losses are bigger than your gains, in the US you can deduct up to $3,000 against ordinary income each year, and carry the rest forward indefinitely. So even a red year can lower this year's tax and pre-load a deduction for later.

But you have to report it

Here's the part people miss: you only get the benefit if you report the sale. Every disposal - even at a loss - is reportable, and with 1099-DA broker reporting phasing in, the IRS increasingly receives your trade data directly. Not reporting a loss doesn't just forfeit the deduction; it creates a mismatch with what the IRS already has.

Turn the loss into a deduction, cleanly

Work out each loss precisely with the cost basis calculator, see how losses net against gains in the tax calculator, and consider deliberately realizing losers to offset winners - that's tax-loss harvesting. Keep the full record in the trading journal so the deduction is defensible.
