Capital Loss Carryforward
A tax provision letting capital losses exceeding what can be deducted in the current year be carried forward to offset gains or income in future tax years.
A capital loss carryforward lets a taxpayer whose capital losses in a given year exceed what they're permitted to deduct against that year's gains and income carry the unused remainder forward into future tax years, where it can offset future capital gains or, often subject to an annual limit, a limited amount of ordinary income. This prevents a large loss realized in one particularly bad year from simply going to waste if it exceeds what that single year's tax rules allow a taxpayer to deduct.
For crypto investors, capital loss carryforwards are particularly relevant after a sharp market downturn, since realized losses from that period — calculated against each asset's cost basis (see Kaavon's "Cost Basis" glossary definition) — can continue offsetting gains for many years afterward, sometimes indefinitely depending on the specific jurisdiction's rules. Accurately tracking carried-forward losses across multiple tax years requires careful recordkeeping, since losing track of an available carryforward means failing to claim a tax benefit the taxpayer may still be legitimately entitled to.
Examples
- An investor realizing a large crypto loss during a market downturn, beyond what that year's rules let them deduct, can carry the unused remainder forward to offset gains in future tax years.
- Careful recordkeeping of a capital loss carryforward across multiple tax years is essential, since losing track of it means missing out on a tax benefit the taxpayer is still entitled to claim.
