Learn how a capital loss carryover works, how the annual deduction limit applies, why short- and long-term character matters, and California rules.
A capital loss carryover is the portion of a taxpayer's net capital loss that cannot be used in the current year and is carried to a later tax year. For individuals, capital losses first offset capital gains; a limited net loss can then reduce other income, and the unused balance generally carries forward while retaining short- or long-term character.
The familiar annual federal deduction limit is generally $3,000, or $1,500 for married taxpayers filing separately. That is not a limit on losses that can offset capital gains. A taxpayer with $50,000 of capital gains may use $50,000 of capital losses before the separate deduction-against-other-income limit becomes relevant.
Schedule D first nets short-term items, then long-term items, and then combines the category results. If the final result is a net capital loss, an individual generally deducts up to the annual limit against other income. The remainder can carry forward.
Example: a taxpayer has a $28,000 net short-term capital loss and a $10,000 net long-term capital gain. Cross-netting leaves an $18,000 net short-term loss. If she uses a $3,000 deduction against other income, up to $15,000 remains for the next year, subject to the Capital Loss Carryover Worksheet.
Next year, the short-term carryover enters the short-term section of Schedule D. It can offset new short-term gains, and any remaining short-term loss can cross-net against net long-term gain. The carryover is not placed into a generic bucket.
The carryover is not always simply prior-year net loss minus $3,000. Taxable income limitations and the Schedule D worksheet can affect the amount used and carried. A copy of the prior return, including worksheets, is more reliable than a summary page or brokerage statement.
On the 2025 federal Schedule D, short-term capital loss carryover enters Part I and long-term capital loss carryover enters Part II. The Capital Loss Carryover Worksheet in the Schedule D instructions determines the amounts. Tax software migration should include both character categories and not merely one total.
A carryover is treated as a loss in the later year, preserving its character, but it does not preserve every attribute of the original transaction for every tax provision. It is different from a suspended passive loss, at-risk carryforward, basis-limited loss, net operating loss, charitable contribution carryover, or vacation-home expense carryforward.
The event that releases one type may not release another. For example, selling a passive activity may release qualifying suspended passive losses, but capital loss carryovers still follow Schedule D netting rules.
An individual's unused capital loss carryover generally does not pass through to beneficiaries after death. Final-year planning and accurate reporting can therefore matter. An estate or trust has its own capital-loss rules, and certain excess deductions or losses on termination require separate analysis.
Marriage, divorce, and changes in filing status can complicate ownership and use of carryovers. Community-property facts, who sustained the original loss, and separate-return limitations may matter. Do not assume a carryover automatically becomes a freely transferable joint attribute.
A disallowed wash-sale loss is generally not a capital loss carryover. It is commonly added to replacement-share basis and its holding period may be adjusted, postponing recognition until a later disposition. Special IRA replacement rules can produce a different, potentially permanent disallowance.
Worthless securities and nonbusiness bad debts have special timing and character rules. A security generally must become wholly worthless in the claimed year. Documentation of identifiable events, liquidation status, and recovery prospects is important.
A carryover can offset future gains, so taxpayers should review it before selling appreciated assets. A large short-term carryover may be especially useful against short-term gains that otherwise face ordinary federal rates. However, tax decisions should consider investment objectives, transaction costs, wash-sale rules, state differences, and income-sensitive provisions.
Carryovers can also interact with capital-gain distributions from mutual funds, gains reported on K-1s, digital-asset transactions, installment-sale payments, and Section 1231 gains that reach Schedule D. Year-end projections should include all sources rather than only brokerage sales.
California maintains its own capital loss carryover calculation. If federal and California basis or prior gain/loss amounts differ, the carryovers can diverge. The 2025 California Schedule D (540) instructions include a California Capital Loss Carryover Worksheet for determining the amount carried to 2026.
California does not provide a lower tax rate for net capital gain, but it still nets capital gains and losses and limits an individual's net capital-loss deduction. Schedule D (540) generally is filed when state gains, losses, or carryovers differ from federal amounts. Preserve both federal and California worksheets every year.
Heath Income Tax can help reconstruct missing carryovers, reconcile federal and California balances, and incorporate them into tax planning and return preparation.
How long can an individual carry a federal capital loss forward?
Generally until used, subject to the rules that apply in each later year; it is not normally limited to a fixed number of years.
Can a carryover offset future capital gains without the $3,000 limit?
Yes. Capital losses offset capital gains before the deduction-against-other-income limit applies.
Are federal and California carryovers always the same?
No. Basis, depreciation, deferral, and other state-law differences can create separate balances.
