Quick answer: An individual's unused net capital loss can generally carry forward without a fixed federal expiration until absorbed. Each year, capital losses first offset capital gains; then up to $3,000 of net loss—$1,500 if married filing separately—can generally offset other income. Remaining loss keeps its short- or long-term character.
This guide translates the controlling rule into filing and recordkeeping steps. It reflects official material available on August 17, 2026. Tax-year forms, software features, state rules and agency procedures can change, so use the instructions for the exact year and transaction involved.

How the rule works
Start by identifying the legal character of the payment, account, credit, deduction, benefit or loan. A marketing label does not control the tax result. Dates, ownership, business purpose, filing status, income limits, residency and documentation can turn a superficially similar situation into a different answer.
- Net short-term and long-term amounts are combined under Schedule D ordering rules before the ordinary-income deduction is determined.
- A carryover is recalculated each year even when the taxpayer has no new transactions.
- Short-term carryover remains short term and long-term carryover remains long term.
- Unused individual capital losses generally end at death rather than transferring to heirs.
- State carryover periods and conformity can differ, so a separate state schedule may be necessary.
Practical example
A taxpayer has a $20,000 net capital loss and no capital gains. After the allowable $3,000 deduction against other income, $17,000 carries to the next year. If the next year has $10,000 of capital gains, the carryover first offsets those gains before another ordinary-income deduction is calculated.
This example isolates the principal rule. It is not a complete return calculation: phaseouts, other credits, state conformity, related-party rules, passive-loss limits and prior-year carryovers may change the outcome.
Step-by-step checklist
- Complete Form 8949 and Schedule D accurately.
- Separate short- and long-term totals.
- Use the official carryover worksheet every year.
- Reconcile prior-year return amounts to software.
- Keep basis, wash-sale and carryover records until fully used.
Reconcile the result to the actual return, notice, lender disclosure or benefit statement before signing. Preserve the source documents, calculations and proof of submission; a software interview or account screen is not a substitute for evidence.
Records to keep
Keep the filed forms and schedules together with receipts, statements, contracts, account records and correspondence that establish amount, date, ownership and purpose. For an asset, credit or carryforward that affects later years, retain the origin-year worksheet through the final disposition or use year and the applicable limitation period.
Common mistakes to avoid
- Entering the prior total carryover entirely as short term.
- Taking more than the annual ordinary-income limit.
- Losing the schedule after switching tax software.
Correct an issuer or agency error through the documented correction process rather than silently changing a reported amount. When the dollars are material, a notice deadline is close, or the facts involve more than one jurisdiction, obtain advice from a credentialed professional who can review the complete record.
