Key Facts
- Federal level: A capital loss generally arises when a capital asset is sold or exchanged for less than its adjusted basis.
- Federal level: Individuals first net capital losses against capital gains according to short-term and long-term categories.
- Federal level: If an individual’s net capital loss exceeds capital gains, the annual deduction against other income is generally limited to $3,000, or $1,500 for married filing separately.
- Federal level: An unused individual capital loss generally carries forward while retaining its short-term or long-term character.
- Federal level: Capital-asset transactions are generally reported on Form 8949 and summarized on Schedule D.
A capital loss is generally the loss recognized when a capital asset is sold or exchanged for less than its adjusted basis. Basis is the property’s tax investment, adjusted under federal rules for relevant events. Market value falling below basis does not ordinarily create a deductible loss until a recognition event occurs.
Capital assets and basis define the starting point
Stocks, bonds, and investment real estate are common capital assets, but the Internal Revenue Code excludes several categories, including inventory and certain business receivables. The classification matters because ordinary-loss and capital-loss rules differ. The separate explanation of adjusted basis describes why purchase price alone may not determine the tax result.
Gain or loss generally equals the amount realized on a sale or exchange minus adjusted basis and applicable transaction adjustments. A loss on personal-use property, such as a personal residence sold at a loss, generally is not deductible. Investment and business contexts can involve additional limitations beyond the basic capital-loss rules.
Holding period determines short-term or long-term character
A capital asset held for one year or less generally produces short-term gain or loss when sold. A capital asset held for more than one year generally produces long-term gain or loss. The holding-period category affects the order in which gains and losses are combined.
Short-term items are netted with other short-term items, and long-term items are netted with other long-term items. If one category produces a gain and the other a loss, those net amounts are then combined. This process determines whether the return has net capital gain or net capital loss after accounting for relevant capital gains.
The individual annual deduction limit
For a taxpayer other than a corporation, capital losses are allowed against capital gains plus a limited amount of other income. Section 1211 sets that additional annual amount at the lower of the net excess loss or $3,000. The limit is $1,500 for a married individual filing a separate return.
The limit applies after capital gains and losses are netted, not separately to every losing transaction. For example, $10,000 of capital losses and $6,000 of capital gains produce a $4,000 net capital loss before the annual deduction limit. In a simplified individual example, up to $3,000 may reduce other income and the unused $1,000 may carry forward.
Carryovers preserve unused losses
Section 1212 generally carries an individual’s unused net capital loss into later tax years. The carryover retains its short-term or long-term character. It enters the later year’s netting process with that year’s transactions and other carryovers.
An individual carryover does not normally expire after a fixed number of years under the federal rule. The amount must still be recomputed each year, and the current year’s allowable deduction is taken into account even if it was not claimed. Corporate capital-loss rules differ materially, including different carryback and carryover periods.
Reporting connects transactions to the net result
Form 8949 generally lists covered sales and exchanges, including proceeds, basis, adjustments, and gain or loss. Short-term transactions appear separately from long-term transactions. The subtotals flow to Schedule D, which performs the category netting and calculates the overall gain or loss.
Broker statements can supply important data, but the tax return may require corrections or information the broker did not report. Records supporting acquisition date, cost, adjustments, sale proceeds, and transaction expenses explain the reported basis and holding period. Capital-loss carryover worksheets preserve the amounts and character moving into the next year.
Special rules can change or postpone a loss
The wash-sale rule can disallow a loss when substantially identical stock or securities are acquired within the statutory period around a loss sale. The disallowed amount generally adjusts the basis of replacement property rather than producing an immediate deduction. Worthless securities, nonbusiness bad debts, related-party transactions, and certain trader elections also have specialized rules.
A federal capital loss does not establish the treatment on a state return. States can differ in conformity, deduction limits, carryover treatment, and reporting. Any concrete state result requires current authority from that state.
