Revenue Procedure 2026-17 lets eligible real estate businesses withdraw an electing real property trade or business election under Section 163(j)(7)(B) that they made for tax years 2022, 2023, or 2024, even though the Internal Revenue Code calls that election irrevocable. The election traded full interest deductibility for mandatory alternative depreciation system treatment, which blocked bonus depreciation. Because the One Big Beautiful Bill Act changed both sides of that trade, the original math may no longer hold. If you withdraw, you are treated as though you never made the election, and depreciation is recalculated. The filing deadline is the earlier of October 15, 2026, or the close of your applicable limitations period.
In 2023, a real estate company in Owensboro, Kentucky made a decision its CPA had modeled carefully. The company was heavily leveraged across several properties, and Section 163(j) was capping its business interest deduction at 30 percent of adjusted taxable income. That cap was expensive. So the company made the electing real property trade or business election, which removed the interest limitation entirely.
The election had a price, and the CPA disclosed it plainly. Electing meant the company had to depreciate certain property under the alternative depreciation system, on longer schedules, and it meant giving up bonus depreciation on affected property. The company ran the numbers, decided the interest deduction was worth more than the delayed depreciation, and signed.
That was a defensible call on the facts as they existed. The problem is that the facts changed underneath it, and the election was supposed to be permanent. The code says irrevocable. The CPA told them so. They moved on.
Then in 2026 the IRS issued Revenue Procedure 2026-17 and reopened the door.
To understand why the reopening matters, you have to understand both halves of the original trade.
Section 163(j) limits the deduction for business interest expense to 30 percent of adjusted taxable income. For a leveraged real estate business, that limitation can strand a large amount of interest expense. The code offers an escape hatch: a real property trade or business can elect out of the limitation under Section 163(j)(7)(B) and deduct its business interest in full.
The cost of that escape is mandatory alternative depreciation system treatment on certain property. Under ADS, residential rental property depreciates over 30 years instead of 27.5. Nonresidential real property depreciates over 40 years instead of 39. Qualified improvement property, which covers many interior improvements to nonresidential buildings, depreciates over 20 years instead of 15.
The longer schedules are annoying. The real cost is something else. Property depreciated under ADS is not eligible for bonus depreciation. Residential rental and nonresidential real property generally would not qualify for bonus anyway, so the ADS treatment costs little there. But qualified improvement property normally does qualify for bonus depreciation. For a business making regular interior improvements, losing bonus on QIP is frequently the single largest cost of the entire election.
So the trade was: full interest deductibility, purchased with slower depreciation and forfeited bonus on QIP. In 2022, 2023, and 2024, with bonus already phasing down and the interest limitation biting hard, a lot of leveraged real estate businesses concluded the trade was worth it. They were often right at the time.
OBBBA moved both sides of the equation, which is why the old conclusions deserve a fresh look.
On the depreciation side, OBBBA permanently restored 100 percent bonus depreciation for qualified property acquired and placed in service after January 19, 2025. Before OBBBA, bonus was on a declining path: 100 percent through 2022, then 80 percent in 2023, 60 percent in 2024, 40 percent in 2025, 20 percent in 2026, and zero in 2027. The thing the election forced you to give up became far more valuable than it was when you gave it up.
On the interest side, OBBBA amended Section 163(j)(8) to restore the add-back for depreciation, amortization, and depletion when computing adjusted taxable income, for tax years beginning after December 31, 2024. That is a technical sentence with a large practical effect. Adding depreciation back increases adjusted taxable income, which increases the 30 percent base the interest limitation is measured against. For many businesses, that change shrinks the limitation substantially or eliminates it outright.
Read those two changes together and the problem becomes obvious. The benefit you bought with the election, escaping the interest limitation, may have gotten much smaller or disappeared. The price you paid, forfeiting bonus depreciation, got much larger. You are potentially still paying full price for something you no longer need.
And under the plain text of the code, you were stuck with it.
The IRS recognized the problem and issued relief. Revenue Procedure 2026-17 does several things.
It permits eligible taxpayers who made the electing real property trade or business election for tax years beginning in 2022, 2023, or 2024 to withdraw that election. Withdrawal is accomplished by filing an amended federal income tax return, an amended Form 1065, or an administrative adjustment request, as applicable, for the year the election was originally made. If you withdraw, you are treated as though the election was never made, and depreciation must be recalculated under the normal, non-ADS rules.
It also permits a late election under Section 168(k)(7). This is a subtle but genuinely useful piece. Withdrawing the election can suddenly make property bonus-eligible that was not bonus-eligible when placed in service, which could dump a very large deduction into an old year, whether or not you want it there. The late Section 168(k)(7) election lets you elect out of bonus depreciation for specific classes of property, so you can withdraw the election you no longer want without being forced to take deductions that create problems in that year. It gives you control over the outcome rather than an all-or-nothing result.
For partnerships subject to the Bipartisan Budget Act of 2015 rules, the guidance provides a streamlined path: file amended Forms 1065 and issue amended Schedules K-1 for 2022, 2023, and 2024, rather than going through the more burdensome administrative adjustment request process.
There is also a mechanical detail worth knowing because people miss it. Amended returns filed under this relief must bear the notation FILED PURSUANT TO REV. PROC. 2026-17, and must include a formal withdrawal statement with the taxpayer's name, address, and taxpayer identification number, along with confirmation of the withdrawal and any late Section 168(k)(7) election.
The filing deadline is the earlier of October 15, 2026, or the end of the applicable period of limitations on assessment for the year being amended. That limitations period generally runs three years from the later of the date the return was filed or the date it was due without regard to extensions.
Note what that means. October 15, 2026 is the outside date. For some taxpayers, particularly on the 2022 year, the limitations period may close sooner. The practical deadline for your specific returns may be earlier than the headline date, which is a reason to start the analysis now rather than in October.
There is more work here than a single amended return, too. If withdrawal changes your depreciation for the election year, it changes subsequent years as well. The guidance requires amended returns for affected succeeding tax years, each subject to its own timing constraints. For a partnership with tiered ownership, the filings ripple out to partners across multiple levels. This is not a form you fill out the week before the deadline.
Here is the connection that matters for property owners, and it cuts in two directions.
If you withdraw the election, property that was locked into ADS returns to normal depreciation treatment, and bonus depreciation becomes available on qualifying property. That is precisely the environment in which a cost segregation study delivers its full value. An engineered study identifies the components of your property that qualify for shorter recovery periods, and with 100 percent bonus restored and the ADS handcuffs removed, those components can produce a substantial deduction. Withdrawing the election without doing the component analysis leaves much of the recovered benefit unclaimed.
If you keep the election, cost segregation still matters, and this is the part most owners get wrong. The election forces ADS treatment on nonresidential real property, residential rental property, and qualified improvement property. It does not sweep in every asset you own. Personal property with shorter recovery periods generally continues under the normal rules and generally remains bonus eligible. So a cost segregation study on an electing business is not a wasted exercise. It is arguably more important, because correctly separating the property that keeps favorable treatment from the property caught by ADS is exactly the analysis that determines your deduction. That is engineering and documentation work, and it is the kind of distinction a cheap software study is poorly equipped to make.
Either way, the decision runs through a component-level understanding of your property. You cannot model the withdrawal accurately without knowing what your property is actually made of.
The analysis is genuinely fact-specific, and it belongs with your CPA. But the shape of it is straightforward, and knowing the shape helps you ask for it.
On one side, quantify what the election is still buying you. Under the restored adjusted taxable income add-back, how much interest expense would actually be limited if you had never elected? For many businesses the answer is far less than it was, and for some the answer is none.
On the other side, quantify what the election has cost you. What depreciation, particularly bonus depreciation on qualified improvement property, did you forfeit in 2022, 2023, and 2024 by sitting under ADS? What is the ongoing cost going forward, given that 100 percent bonus is now permanent rather than phasing out?
Then compare, remembering that withdrawal is not free of friction. There are amended returns for the election year and every affected subsequent year, potential amended K-1s for every partner, capital account adjustments for partnerships, basis adjustments on affected property, and professional fees to do all of it correctly. A withdrawal that recovers a modest amount may not survive the cost of executing it. A withdrawal that recovers a large amount very likely will.
Keith Cunningham's discipline is the right frame. The election was a decision made against a set of facts. The facts moved. The only question worth asking is whether the decision still holds against the facts as they are now, and the only way to answer it is to run the numbers rather than assume the old answer still stands.
Assuming irrevocable still means irrevocable. The code says irrevocable, your CPA correctly told you so at the time, and that was true until the IRS provided this relief. Anyone relying on their 2023 understanding will miss the window entirely.
Waiting until October. The outside deadline is October 15, 2026, but your actual deadline may be earlier if a limitations period closes first, and the work involves multiple years and potentially many partners. Late starts fail.
Withdrawing without modeling it. Withdrawal is not automatically favorable. If the interest limitation would still bite hard in your situation, the election may still be the right answer. Model it before you file anything.
Forgetting the late bonus election. Withdrawal can force large deductions into old years whether you want them or not. The late Section 168(k)(7) election is the control valve, and taxpayers who do not know it exists lose the ability to shape the outcome.
Ignoring the succeeding years. The election year is not the only return affected. Subsequent years need amending too, each with its own deadline.
Skipping the component analysis. Whether you withdraw or keep the election, the deduction depends on what your property is made of. An engineered cost segregation study is what turns the decision into dollars.
If you or an entity you own made an electing real property trade or business election for a tax year beginning in 2022, 2023, or 2024, this is worth a conversation with your CPA this month, not in October. The question to put to them is simple: given the restored adjusted taxable income add-back and permanent 100 percent bonus depreciation, does our original election still make sense, and if not, what would withdrawal recover net of the cost of amending?
On the property side, the Cost Seg America team builds the engineered component analysis that either scenario depends on. If you withdraw and want to capture the bonus depreciation the election had blocked, the study is what identifies it. If you keep the election, the study is what correctly separates the property still eligible for favorable treatment from the property caught by ADS.
The Cost Seg America team has completed more than 16,000 studies and defended studies through more than 125 IRS audits with zero losses and zero dollars ever returned to the IRS. Across those studies the average first-year savings is $438,511. Engineered, not estimated.
The IRS rarely reopens a door it has called permanently closed. This one is open until October 15, 2026, and for some returns it closes sooner.

What is Revenue Procedure 2026-17?
It is IRS guidance allowing eligible real estate businesses to withdraw an electing real property trade or business election under Section 163(j)(7)(B) made for tax years beginning in 2022, 2023, or 2024, even though that election is otherwise irrevocable under the code.
Why would I want to withdraw the election now?
Because the One Big Beautiful Bill Act changed both sides of the original trade. It restored the depreciation, amortization, and depletion add-back in computing adjusted taxable income for tax years beginning after December 31, 2024, which shrinks or eliminates the interest limitation the election was meant to escape. It also made 100 percent bonus depreciation permanent, which makes the bonus you forfeited far more valuable.
What is the deadline?
The earlier of October 15, 2026, or the end of the applicable period of limitations on assessment for the year being amended. Your practical deadline may be earlier than October 15, so the analysis should start well before then.
What did the election cost me?
Mandatory alternative depreciation system treatment on certain property: 30 years for residential rental instead of 27.5, 40 years for nonresidential real property instead of 39, and 20 years for qualified improvement property instead of 15. ADS property is not eligible for bonus depreciation, and lost bonus on qualified improvement property is often the largest cost.
Is withdrawal always the right move?
No. If the interest limitation would still meaningfully restrict your deduction, the election may still be correct. Withdrawal also carries real execution cost: amended returns for the election year and every affected subsequent year, amended K-1s for partners, capital account and basis adjustments, and professional fees. Model it before filing.
Does cost segregation still help if I keep the election?
Yes. The election forces ADS on nonresidential real property, residential rental property, and qualified improvement property, but personal property with shorter recovery periods generally keeps normal treatment and generally remains bonus eligible. An engineered study is what correctly separates the two.
