On an individual return, the capital loss deduction limit is $3,000 per year against ordinary income, or $1,500 if you’re married filing separately. Losses above that ceiling don’t disappear. They carry forward to future tax years with no expiration, keeping their short-term or long-term character, until you’ve used them up.1Office of the Law Revision Counsel. 26 USC 1211 Limitation on Capital Losses2Office of the Law Revision Counsel. 26 USC 1212 Capital Loss Carrybacks and Carryovers
The $3,000 figure has been frozen since 1978. It doesn’t adjust for inflation, so it covers less real income every year, but the mechanics haven’t changed.
How the $3,000 Cap Is Applied
Capital losses don’t go straight to reducing your wages. They first cancel out any capital gains you realized during the same year. Only the leftover loss — the amount that exceeds your total gains — gets applied against ordinary income, and that’s where the ceiling kicks in.1Office of the Law Revision Counsel. 26 USC 1211 Limitation on Capital Losses
Say you sold one stock for a $15,000 gain and another for a $22,000 loss. Your losses exceed your gains by $7,000. You deduct $3,000 of that against your salary, interest, or other ordinary income. The remaining $4,000 carries to next year.
If your losses only exceeded your gains by $2,000, you’d deduct the full $2,000. No carryover. The $3,000 is a ceiling, not a fixed deduction. You use what you actually lost.
The Netting Order That Comes Before the Cap
The IRS requires a specific sequence when calculating your net capital position. Short-term and long-term transactions are handled separately before being combined.3Internal Revenue Service. Topic No. 409, Capital Gains and Losses
- Net your short-term transactions. Add all short-term gains, subtract all short-term losses. $5,000 in short-term gains against $8,000 in short-term losses leaves a $3,000 net short-term loss.
- Net your long-term transactions the same way. $2,000 in long-term gains against $1,000 in long-term losses leaves a $1,000 net long-term gain.
- Combine the two results. The $3,000 net short-term loss absorbs the $1,000 net long-term gain, leaving an overall $2,000 net capital loss. That falls under the cap, so it’s fully deductible this year.
An asset held one year or less produces short-term results; longer than a year produces long-term. Counting starts the day after you acquire the asset and includes the day you sell.4Internal Revenue Service. FS-2007-19, Reporting Capital Gains
What Happens to Losses Above $3,000
The excess carries forward to next year’s return. There’s no expiration, whether that takes two years or twenty.2Office of the Law Revision Counsel. 26 USC 1212 Capital Loss Carrybacks and Carryovers
The carryover keeps its character. A short-term loss carryover enters next year’s netting as a short-term loss, and long-term stays long-term. In the following year, it offsets same-character gains first, then cross-character gains, and finally up to $3,000 of ordinary income again.
Example: you realize a $10,000 net short-term loss this year. You deduct $3,000 now and carry $7,000 forward. Next year you have $4,000 in short-term gains and no other capital activity. The $7,000 carryover wipes out the $4,000 gain and leaves a $3,000 net loss, which you again deduct against ordinary income. Nothing left to carry after that.
Carryovers Do Not Survive Death
Capital loss carryovers belong to the individual taxpayer. A carryover can be used on the decedent’s final income tax return, but the estate cannot claim it and beneficiaries cannot inherit it.5Internal Revenue Service. Decedents and Related Issues If you’re sitting on large unused losses, that’s worth factoring into end-of-life planning.
Married Filing Separately
The mechanics stay the same, but the annual cap drops to $1,500 per spouse, and each spouse tracks their own gains, losses, and carryovers independently.1Office of the Law Revision Counsel. 26 USC 1211 Limitation on Capital Losses
The Wash Sale Rule Can Erase Your Deduction
You can’t sell a stock at a loss, immediately buy it back, and claim the loss. If you repurchase the same or a substantially identical security within 30 days before or after the sale, the loss is disallowed. The window covers 61 days total: 30 before, the sale date, and 30 after.6Office of the Law Revision Counsel. 26 USC 1091 Loss From Wash Sales of Stock or Securities
The disallowed loss isn’t gone forever. It gets added to your cost basis in the replacement shares, reducing your taxable gain (or increasing your deductible loss) when you eventually sell those. Buy replacement stock for $800 with a $250 disallowed loss, and your new basis is $1,050.7Internal Revenue Service. Case Study 1 Wash Sales
The rule catches more than obvious repurchases. Buying an option or contract to acquire substantially identical stock triggers it. It also crosses the calendar-year boundary. Sell December 15, buy January 4, still a wash sale.
Losses You Can’t Deduct at All
Personal-Use Property
Selling your home, car, furniture, or other personal belongings at a loss produces no deductible capital loss. Federal law limits individual loss deductions to trade or business losses, profit-seeking transaction losses, and certain casualty or theft losses.8Office of the Law Revision Counsel. 26 US Code 165 – Losses A loss on your primary residence or personal vehicle doesn’t fit any of those categories.9Internal Revenue Service. What if I Sell My Home for a Loss The gain on a home sale can be taxable (above the Section 121 exclusion), but a loss on the same house isn’t deductible.
Sales to Related Parties
Selling an asset at a loss to a family member or an entity you control disqualifies the loss entirely. Family here includes your spouse, siblings, parents, grandparents, children, and grandchildren. It also covers sales to a corporation where you own more than 50% of the stock.10Office of the Law Revision Counsel. 26 US Code 267 – Losses, Expenses, and Interest With Respect to Transactions Between Related Taxpayers If the related buyer later sells to an unrelated third party at a gain, that gain is recognized only to the extent it exceeds the previously disallowed loss, so the loss can effectively shift to offset the buyer’s future gain, though it can’t create a deductible loss for the buyer.
Situations That Change the Usual Limit
Section 1244 Small Business Stock
Losses on qualifying small business stock can be treated as ordinary losses rather than capital losses, bypassing the $3,000 cap entirely. The ordinary loss limit is $50,000 per year for single filers and $100,000 for married couples filing jointly.11Office of the Law Revision Counsel. 26 USC 1244 Losses on Small Business Stock
To qualify, the stock must have been issued by a domestic corporation that received no more than $1,000,000 in total capital contributions (including amounts for all previously issued stock) at the time of issuance. The corporation must have earned more than half its gross receipts from active business operations rather than passive income like dividends, rents, or royalties during the five years before the loss. You must be the original purchaser; buying secondhand on the market doesn’t count.
Worthless Securities
When a stock or bond becomes completely worthless, you don’t need to actually sell it to claim the loss. The IRS treats it as sold on the last day of the tax year in which it became worthless.12Internal Revenue Service. Losses – Homes, Stocks, Other Property That date determines whether the loss is short-term or long-term. Pinpointing the year of worthlessness can be tricky, but you generally have seven years (not the usual three) to file a refund claim for worthless securities.
Nonbusiness Bad Debts
A personal loan to a friend or family member that becomes completely uncollectable can be treated as a short-term capital loss regardless of how long the loan was outstanding. Partially worthless personal debts don’t qualify; the debt must be totally worthless.13Internal Revenue Service. Topic No. 453, Bad Debt Deduction Because it’s a short-term capital loss, it runs through the same netting process and lives under the same $3,000 annual cap.
Corporations Follow Different Rules
The $3,000 figure applies to individuals. C-corporations cannot deduct capital losses against ordinary income at all. Corporate capital losses can only offset corporate capital gains in the same year. Unused losses carry back three years and forward five years, but they never reduce operating income.1Office of the Law Revision Counsel. 26 USC 1211 Limitation on Capital Losses Pass-through entities like S-corporations and partnerships don’t face this restriction at the entity level; their gains and losses flow through to owners’ individual returns and follow the individual rules.
Reporting the Loss on Your Return
Capital losses are reported on Form 8949 and Schedule D, filed with your Form 1040.14Internal Revenue Service. Instructions for Form 8949 (2025) Form 8949 lists each transaction, separated into short-term (Part I) and long-term (Part II). The totals feed into Schedule D, which performs the netting, applies the $3,000 deduction limit, and calculates any carryover.15Internal Revenue Service. 2025 Instructions for Schedule D (Form 1040)
Most brokerages provide a year-end Form 1099-B reporting sales proceeds and cost basis. If your broker reported the basis to the IRS, use those figures and make any needed corrections in the adjustment column. Keep your own records anyway. Brokers sometimes get basis wrong on inherited shares, gifted stock, or shares from corporate spinoffs, and the carryover you claim in year twenty depends on the numbers being right in year one.
