If your crypto portfolio declined and you sold at a loss, those losses have tax value. Capital losses offset capital gains dollar for dollar with no limit. Excess losses offset up to $3,000 of ordinary income per year. Unused losses carry forward indefinitely. Understanding how to use crypto losses strategically can save you thousands.

Realizing the Loss

An unrealized loss — crypto that has declined but you have not sold — has no tax value. You must sell, trade, or otherwise dispose of the asset to realize the loss. Simply holding depreciated crypto does not produce a deductible loss. The disposition must be a completed transaction — selling on an exchange, trading for another crypto, or sending to a burn address all qualify.

Short-Term vs. Long-Term

Short-term capital losses (on assets held one year or less) first offset short-term capital gains. Long-term capital losses first offset long-term capital gains. Then net short-term and net long-term results offset each other. Because short-term gains are taxed at higher rates, generating short-term losses to offset short-term gains produces a larger tax benefit per dollar of loss.

The $3,000 Limitation

If your total capital losses exceed your total capital gains, you can deduct up to $3,000 of the excess against ordinary income ($1,500 if married filing separately). Any remaining loss carries forward to the next year, retaining its character as short-term or long-term. A taxpayer with $100,000 in crypto losses and no gains would deduct $3,000 per year for over 33 years — or until future gains absorb the losses.

Worthless Crypto

If a cryptocurrency becomes completely worthless — a rug pull, a dead project, an exchange collapse — you can claim a loss under §165. The loss equals your full basis in the asset. The challenge is establishing the date the crypto became worthless, as this determines the tax year in which the loss is deductible. Documentation of worthlessness — zero trading volume, delisted from exchanges, project abandoned — supports the deduction.

Strategic Application

Crypto losses are most valuable when used strategically — offsetting high-taxed short-term gains, reducing adjusted gross income to preserve other tax benefits, or carrying forward to offset future gains.
