Capital losses from a taxable brokerage account can offset IRA distributions, but only up to $3,000 of ordinary income per year ($1,500 if you’re married filing separately).1Office of the Law Revision Counsel. 26 USC 1211 – Limitation on Capital Losses Traditional IRA withdrawals are taxed as ordinary income, and capital losses first have to absorb any capital gains you realized during the year; only the leftover loss trickles over to reduce ordinary income, and only within that annual cap. The $3,000 ceiling has not moved since 1978 and isn’t indexed to inflation, so treat it as a modest tool rather than a shield against a large distribution.
Why a Full Offset Isn’t Possible
Selling a stock or bond in a regular brokerage account for less than you paid produces a capital loss, and the tax code treats most personal investments as capital assets governed by their own rules.2Office of the Law Revision Counsel. 26 USC 1221 – Capital Asset Defined
Traditional IRA distributions sit in a different bucket. Every dollar you withdraw is included in gross income and taxed at your ordinary rates, the same way wages or interest are taxed.3Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts Because capital losses and retirement income sit in separate tax categories, they don’t wipe each other out dollar for dollar. The code provides only a narrow bridge between them.
How the $3,000 Limit Actually Works
The offset follows a specific order. Your capital losses first absorb any capital gains you realized during the same tax year. Lose $15,000 on one position and gain $8,000 on another, and the two net to a $7,000 loss. Only then does the ordinary-income offset come into play.4Office of the Law Revision Counsel. 26 USC Subtitle A, Chapter 1, Subchapter P, Part II – Treatment of Capital Losses
From that remaining net loss, you can deduct up to $3,000 against other income on your return. If you’re married filing separately, the cap is $1,500.1Office of the Law Revision Counsel. 26 USC 1211 – Limitation on Capital Losses That deduction reduces your total taxable income, which effectively reduces the tax on whatever ordinary income makes up the total, including an IRA withdrawal. In the example above, only $3,000 of the $7,000 net loss would offset ordinary income this year.
The cap applies no matter how large the distribution. A $50,000 IRA withdrawal paired with a $30,000 net capital loss still yields only a $3,000 deduction against ordinary income for the year. The rule catches people out because they expect a proportional offset.
What Happens to the Rest of the Loss
The unused portion doesn’t disappear. In that same example, the remaining $4,000 carries into the next tax year, where it once again absorbs capital gains first and then up to $3,000 of ordinary income.4Office of the Law Revision Counsel. 26 USC Subtitle A, Chapter 1, Subchapter P, Part II – Treatment of Capital Losses The cycle repeats every year until the loss is used up. A single brutal year in the market can produce a carryforward that takes a decade to absorb at $3,000 a year.
Carryovers die with the taxpayer. If you pass away with an unused balance, your estate cannot keep deducting it. The one exception is the final return itself: a surviving spouse can file jointly for the year of death and use the carryover on that return, but anything left over after that is gone.5Internal Revenue Service. IRS Resource Guide – Decedents and Related Issues For a large carryover, it can be worth accelerating capital gains in later years to draw it down rather than letting it expire.
Losses Inside the IRA Don’t Count
This is where most of the confusion lives. A stock that drops 40% inside your traditional IRA is not a realized capital loss in any tax-relevant sense. Everything inside a traditional IRA sits in a tax-deferred shell: gains aren’t taxed as they occur, and losses don’t produce deductions. The IRS doesn’t track cost basis on individual holdings within the account.
When you eventually withdraw money, the entire distribution is taxed as ordinary income regardless of which holdings inside the account went up or down. A stock that lost half its value inside the IRA simply results in a smaller account balance and, eventually, a smaller taxable withdrawal. The loss is reflected indirectly through lower distributions over your lifetime, not through a deductible event on any tax return.
The Wash Sale Trap With IRA Purchases
Selling a losing stock in a taxable account and buying the same stock in your IRA within 30 days triggers the wash sale rule. The IRS treats it as if you repurchased a substantially identical security, and the capital loss from the taxable sale is disallowed.6Internal Revenue Service. IRS Publication 550 – Investment Income and Expenses
Normally, a disallowed wash sale loss gets added to the cost basis of the replacement shares, so you recover it later when you sell those shares. Not here. Because IRAs don’t track individual cost basis, the IRS has ruled that a wash sale with an IRA replacement permanently forfeits the loss. You don’t get it back in any form.6Internal Revenue Service. IRS Publication 550 – Investment Income and Expenses
The 30-day window runs both directions. If you plan to harvest a loss in a taxable account, don’t buy the same security in any account, including an IRA, during the 61 days around the sale.
Roth Distributions Are a Different Story
Qualified distributions from a Roth IRA are entirely tax-free. If you’re at least 59½ and the account has been open five years or more, withdrawals don’t appear as taxable income at all, so there’s nothing for the $3,000 deduction to offset.
Non-qualified Roth distributions are different. If you pull earnings before meeting both the age and five-year requirements, those earnings are taxed as ordinary income and may also carry a 10% early withdrawal penalty. In that narrow case, the $3,000 capital loss deduction applies to the taxable earnings portion the same way it applies to a traditional IRA distribution. Contributions come out tax-free and penalty-free regardless of timing.
Why $3,000 Can Matter More Than It Looks
The direct tax savings from a $3,000 deduction are small. But for retirees sitting near certain income thresholds, that same deduction can prevent surcharges and phase-ins that dwarf the savings on the deduction itself.
Medicare IRMAA Surcharges
Medicare Part B and Part D premiums step up at specific modified adjusted gross income levels. For 2026, a single filer crossing $109,000 in MAGI pays an extra $81.20 per month for Part B and $14.50 for Part D. Joint filers hit the first surcharge at $218,000, and the surcharges climb steeply at higher brackets, reaching nearly $487 per month for Part B alone at the top tier.7CMS. 2026 Medicare Parts A and B Premiums and Deductibles Because MAGI includes IRA distributions, a large withdrawal can push you into a higher bracket. A $3,000 capital loss deduction shaves MAGI, and if you’re just above a threshold, that can be the difference between paying a surcharge for the year and not.
Social Security Benefit Taxation
Whether Social Security benefits are taxable turns on “combined income,” which is half your benefits plus other taxable income. For single filers, benefits start becoming taxable at $25,000 of combined income, with up to 85% taxable above $34,000. For joint filers, the thresholds are $32,000 and $44,000.8Office of the Law Revision Counsel. 26 USC 86 – Social Security and Tier 1 Railroad Retirement Benefits Like the $3,000 cap itself, these thresholds have never been indexed for inflation, so more retirees cross them each year. Lowering ordinary income by even a small amount can drop the taxable percentage of your benefits.
The 3.8% Net Investment Income Tax
The net investment income tax adds 3.8% on investment income for taxpayers whose MAGI exceeds $200,000 (single) or $250,000 (joint).9Office of the Law Revision Counsel. 26 USC 1411 – Imposition of Tax IRA distributions aren’t themselves classified as net investment income, but they raise MAGI, which can pull more of your dividends, interest, and capital gains under the 3.8% tax. A $3,000 deduction that trims MAGI can reduce or eliminate NIIT exposure in a year when a large withdrawal puts you near the threshold. These thresholds also aren’t indexed for inflation.
How to Claim the Offset on Your Return
A handful of forms carry the numbers from your brokerage statements to the line on Form 1040 where the offset actually happens:
- Form 1099-B, which your brokerage sends after each tax year, showing proceeds and cost basis for every sale in your taxable accounts.10Internal Revenue Service. Instructions for Form 1099-B (2026)
- Schedule D (Form 1040), where you net all capital gains and losses for the year and calculate the total net capital loss.10Internal Revenue Service. Instructions for Form 1099-B (2026)
- Form 1099-R, which reports the total and taxable portions of your IRA distributions for the year.
- Form 1040, where the net capital loss from Schedule D (up to $3,000, or $1,500 if married filing separately) goes on the capital gains line, directly reducing adjusted gross income.11Internal Revenue Service. Topic No. 409, Capital Gains and Losses
If you’re carrying forward losses from prior years, track the unused amount yourself. The IRS doesn’t send a reminder. Use the Capital Loss Carryover Worksheet in the prior year’s Schedule D instructions to find the amount that rolls into the current year. Missed carryforwards are a common casualty of switching tax preparers.
One state-level caveat. A few states don’t conform to the federal $3,000 deduction or set their own limits on capital loss offsets against ordinary income. If your state has an income tax, check its rules before assuming the same deduction applies on your state return.
