The IRS Just Gave Real Estate Businesses a One-Time Chance to Undo an Irrevocable Tax Election, And the Deadline Is October 15

If you own a real estate business that elected out of the Section 163(j) business interest limitation, you need to read this carefully. On March 18, 2026, the IRS released Revenue Procedure 2026-17, which does something that almost never happens in tax law: it gives taxpayers a one-time opportunity to withdraw an irrevocable statutory election. That election, made under IRC § 163(j)(7) to be treated as an "electing real property trade or business", was a perfectly rational choice when it was made. But the One Big Beautiful Bill Act, signed into law on July 4, 2025, fundamentally changed the math. Businesses that opted out of the interest limitation in exchange for giving up bonus depreciation are now stuck in an election that costs more than it saves. Rev. Proc. 2026-17 lets them unwind it, but only if they file amended returns by October 15, 2026.

To understand why this matters, you need to understand the original tradeoff. Section 163(j), as introduced by the Tax Cuts and Jobs Act of 2017, limits the amount of business interest a taxpayer can deduct. The general rule caps the deduction at 30 percent of adjusted taxable income. For the first several years, adjusted taxable income was calculated on an EBITDA basis, earnings before interest, taxes, depreciation, and amortization. That was a relatively generous calculation, especially for capital-intensive businesses, because adding back depreciation and amortization to income gave taxpayers a larger base against which to measure their 30-percent limit.

But the TCJA included a sunset provision. Starting in 2022, the calculation changed to an EBIT basis, earnings before interest and taxes only, without the depreciation and amortization addback. That change dramatically tightened the limitation for businesses with significant depreciation deductions. Real estate companies, farming operations, and regulated utilities, all industries with heavy capital investment and correspondingly large depreciation, were hit hardest.

Section 163(j)(7) offered those businesses an escape. By making an election, a qualifying real property trade or business, electing a farming business, or an excepted regulated utility trade or business could opt out of the § 163(j) limitation entirely. No cap on interest deductions. The catch was that businesses electing to use the alternative depreciation system for certain property had to use longer recovery periods and, critically, no bonus depreciation under § 168(k). The election was irrevocable. Once made, there was no going back.

At the time, the tradeoff made sense for many real estate businesses. If you were carrying substantial debt and your interest expense was being capped by § 163(j), giving up bonus depreciation was a price worth paying to deduct all of your interest. The EBIT calculation had made the cap so tight that interest deductions were being permanently lost. Bonus depreciation was phasing down anyway, from 100 percent in 2022 to 80 percent in 2023, 60 percent in 2024, and so on. The election looked like the better deal.

Then the One Big Beautiful Bill Act changed everything. OBBBA made two critical amendments. First, it permanently restored the adjusted taxable income calculation to an EBITDA basis for taxable years beginning after December 31, 2024. That means depreciation and amortization are once again added back to income when computing the § 163(j) limitation, which significantly increases the amount of interest a taxpayer can deduct without needing the election at all. Second, OBBBA permanently established 100 percent bonus depreciation under § 168(k) for qualifying property acquired after January 19, 2025. That is not a phase-in or a temporary extension; it is a permanent feature of the tax code.

The combined effect of these two changes is devastating for taxpayers who made the § 163(j)(7) election. Before OBBBA, those taxpayers gave up bonus depreciation in exchange for unlimited interest deductions. After OBBBA, the interest limitation is much more generous for everyone, electing and non-electing businesses alike, because the EBITDA calculation produces a higher limit. But electing businesses are still locked out of bonus depreciation. They gave up a benefit that is now permanent and far more valuable than it was when they made the election, and they got in return an exemption from a limitation that is no longer as restrictive as it used to be.

Revenue Procedure 2026-17 addresses this problem by offering a one-time withdrawal opportunity. Taxpayers who made an election under § 163(j)(7) for taxable years beginning in 2022, 2023, or 2024 may withdraw that election by filing amended returns covering all years during which the election was in effect. The amended returns must be filed by October 15, 2026. Upon withdrawal, the taxpayer is treated as if the election had never been made, it reverts to non-electing status and becomes subject to the § 163(j) limitation as revised by OBBBA for the amended years.

The withdrawal decision is not automatic and requires careful analysis. The first question is whether the EBITDA-based calculation, combined with the taxpayer's actual depreciation and amortization deductions, produces a § 163(j) limitation that is large enough to absorb most or all of the taxpayer's business interest expense. If so, the taxpayer does not need the election, and withdrawing it unlocks 100 percent bonus depreciation going forward, and potentially retroactively for the amended years.

But bonus depreciation is not always beneficial. A large first-year depreciation deduction could generate or increase a net operating loss that the taxpayer cannot fully utilize. Under post-TCJA rules, NOLs can only offset 80 percent of taxable income in future years and cannot be carried back. If bonus depreciation creates a loss that sits on the books for years without being absorbed, the time value of money erodes the benefit. Rev. Proc. 2026-17 anticipates this issue by permitting taxpayers to retroactively elect out of bonus depreciation under § 168(k)(7) on the same amended return where the § 163(j)(7) election is withdrawn. The § 168(k)(7) election is made on a class-by-class basis, so a taxpayer can claim bonus depreciation on some asset classes while electing out for others. That flexibility allows for a tailored depreciation strategy that optimizes the overall tax position.

Partnerships face additional procedural considerations. Under the centralized audit regime established by the Bipartisan Budget Act of 2015, partnerships that need to correct prior-year returns generally must file an administrative adjustment request, a complex and burdensome process. Rev. Proc. 2026-17 simplifies this by permitting eligible partnerships to file amended Forms 1065 and issue amended Schedules K-1 instead. That is a significant procedural benefit that reduces both cost and complexity for partnership filers.

Large corporate taxpayers should also consider the corporate alternative minimum tax under Section 55. The CAMT imposes a book minimum tax on corporations with average adjusted financial statement income exceeding $1 billion. Because bonus depreciation creates large book-tax differences, tax depreciation is accelerated while book depreciation remains on the original schedule, withdrawing the § 163(j)(7) election and claiming bonus depreciation could increase adjusted financial statement income and trigger or increase a CAMT liability. The IRS has issued some interim guidance in Notice 2026-7 providing favorable adjustments to AFSI for certain items, but taxpayers should model both the regular tax and CAMT impacts before making a decision.

For taxpayers currently under IRS examination, there is an additional wrinkle. Amended returns filed under Rev. Proc. 2026-17 must be provided to the examining revenue agent contemporaneously with filing, and those returns may receive heightened scrutiny. The underlying analysis supporting the withdrawal, including the comparative benefit analysis and all collateral adjustments, should be thoroughly documented and contemporaneously prepared.

The bottom line for real estate businesses, farming operations, and regulated utilities is this: the § 163(j)(7) election that made sense in 2022 or 2023 may no longer make sense after OBBBA. The IRS is giving you a one-time chance to fix it, but the window closes on October 15, 2026. If you made this election, you should be modeling the impact of withdrawal now, not in September. The analysis involves comparing your interest deductions under the election versus under the EBITDA-based limitation, quantifying the value of bonus depreciation you would recapture, evaluating whether that depreciation creates adverse NOL or CAMT consequences, and determining whether a class-by-class § 168(k)(7) election optimizes the result.

This is not a decision to make based on a rule of thumb or a gut feeling. It requires a detailed, year-by-year analysis of the taxpayer's actual numbers. But for many capital-intensive real estate businesses that have been locked out of bonus depreciation since 2022, the math is likely to favor withdrawal. The sooner you run the analysis, the more time you have to prepare the amended returns and make a fully informed decision.
