Excess Business Loss Limitation 2026: $256,000 / $512,000 Cap
The excess business loss limitation in §461(l) caps how much net loss from your businesses can offset other income, such as wages, interest and investment gains, in one year. For 2026 the cap is $256,000, or $512,000 on a joint return (Rev. Proc. 2025-32 §3.31). Business losses above that are not lost. They become a net operating loss (NOL) carryforward to next year.
It matters to real estate owners in three situations: a real estate professional with a big cost segregation year, a short-term rental owner who materially participates, and a seller whose suspended passive losses are released in one lump.
The numbers
| Year | Single and others | Married filing jointly | Source |
|---|---|---|---|
| 2025 | $313,000 | $626,000 | Form 461 instructions (Rev. Proc. 2024-40) |
| 2026 | $256,000 | $512,000 | Rev. Proc. 2025-32 §3.31 |
The 2026 amount is lower than 2025 because P.L. 119-21 re-based the inflation adjustment. The same law made the rule permanent: §70601 struck the "before January 1, 2029" end date for taxable years beginning after December 31, 2026. There is no scheduled sunset.
How the limit is computed
An "excess business loss" is the amount by which your total deductions from trades or businesses exceed your total gross income and gains from trades or businesses, plus the threshold amount.
Three details decide most real cases:
- Wages do not count. The Form 461 instructions say the excess is determined "without regard to any deductions, gross income, or gains attributable to any trade or business of performing services of an employee." A surgeon's salary cannot absorb a real estate business loss under this test.
- Capital gains count only in part. Under §461(l)(3)(B)(ii), capital gain is included only up to the lesser of capital gain net income from the businesses or total capital gain net income. Losses from sales of capital assets are left out of the deduction side.
- Trade or business is a facts-and-circumstances question. The Form 461 instructions describe it as an activity carried on for income or profit "with continuity and regularity." For a partnership or S corporation, that determination is made at the entity level.
Whether a rental counts as a "trade or business" here is its own question. Losses of a real estate professional's rentals are business deductions for §461(l) only if the rental rises to a §162 trade or business. Ask your CPA how your rentals are treated before you rely on either answer.
The order of the loss limits
Losses face four gates, in this order:
| Order | Rule | What it asks |
|---|---|---|
| 1 | Basis (partners and S corporation shareholders) | Do you have basis in the entity? |
| 2 | At-risk, §465 | Are you economically at risk for the amount? (at-risk rules) |
| 3 | Passive activity, §469 | Is the loss passive, and do you have passive income? |
| 4 | Excess business loss, §461(l) | Does your net business loss exceed $512,000 (joint)? |
The Form 461 instructions state the last three directly: "First, apply the at-risk rules; next, apply the passive activity loss rules; and then apply the excess business loss rules." §461(l)(6) says the same thing: "This subsection shall be applied after the application of section 469."
So a passive loss that is suspended on Form 8582 never reaches §461(l) that year. It enters the §461(l) computation only in the year §469 allows it.
A simple example: the cap and the NOL
A simple example: A married couple has $900,000 of W-2 income and takes the $32,200 standard deduction. One spouse is a real estate professional, and a cost segregation year produces a $700,000 nonpassive business loss with no other business income. §461(l) allows $512,000. The other $188,000 becomes an NOL carryforward.
Federal income tax with no loss at all: about $243,300. With the $512,000 allowed: about $70,600. If there were no cap and all $700,000 were allowed: about $26,300. The cap costs about $44,200 this year.
Next year, with the same wages, the $188,000 NOL is deductible (well under the 80%-of-taxable-income limit in §172(a)(2)) and saves about $67,800. The cap moved the deduction; it did not destroy it (2026 MFJ brackets, §1(h)(1) worksheet order, NIIT and state tax ignored).
The NOL limit is the second catch. A post-2017 NOL can offset only 80% of taxable income computed without the NOL (§172(a)(2)(B)(ii)). In a year with little income, part of the NOL keeps carrying forward.
Why this matters when you sell
When you sell your entire interest in a passive activity to an unrelated buyer in a fully taxable sale, §469(g) releases its suspended losses. Released losses are treated as "not from a passive activity." That is good news. But if they are business losses, they now enter the §461(l) test in the year they are released.
A seller with a large reservoir can release more in one year than the cap allows:
- Cash sale: the whole reservoir is released at once. If the released business losses, net of that year's business income and gain, exceed $512,000, the excess becomes an NOL and waits.
- Installment sale: §469(g)(3) releases suspended losses each year in proportion to the gain recognized that year over total gross profit. Spreading the gain spreads the release. A reservoir that would blow through the cap in one year can fit under it in each of several.
A simple example: $1,000,000 of released business losses in one year, with $300,000 of business income and gain that year, leaves a $700,000 net business loss. $512,000 is allowed; $188,000 becomes an NOL. Released over four years at $250,000 a year, each year's net loss is well under the cap (numbers are illustrative; the actual business income each year changes the result).
This is one more reason timing matters. The same losses can be worth more when they arrive in steps. The book calls it the waterfall; see how an installment sale meters out suspended losses and what happens to suspended passive losses at sale.
Who runs into it
- Real estate professionals with a cost segregation or bonus year. See bonus depreciation on rental property.
- Short-term rental owners who materially participate and take large first-year losses. See short-term rental tax strategy.
- K-1 investors with nonpassive losses from businesses they work in. Losses that pass through as passive stay on Form 8582 until released.
- Sellers releasing a large suspended reservoir in a cash sale.
- Farmers, who have special NOL ordering rules; see the Form 461 instructions.
Reporting: Form 461
Form 461 computes the limit. Business income, gains and losses from your schedules, Form 4797 and K-1s flow in, and the disallowed excess is added back to income on your return for the year. The NOL carryforward is then tracked like any other NOL. The IRS posts the Form 461 instructions.
Bottom line
The excess business loss limitation is the last gate a loss passes through, after at-risk and the passive rules. In 2026 it caps net business losses at $512,000 for a joint return and turns the rest into an NOL that can offset only 80% of a later year's taxable income. For sellers, a lump release of suspended losses can run into it; an installment sale that releases losses in proportion to the gain can keep each year under the cap.

Questions to ask your CPA
- Which of my losses are business losses for §461(l), and are my rentals a §162 trade or business?
- How much of this year's loss is limited by at-risk or passive rules before §461(l) even applies?
- If I sell for cash, how much suspended loss is released, and will any of it become an NOL?
- Would an installment sale keep each year's released losses under $512,000?
- How much NOL am I carrying, and how does the 80% limit affect when I use it?
