IRS Provides Guidance on Business Interest Limitation Elections

Why It Matters

The new procedures give corporations greater flexibility in managing interest deductions and depreciation strategies, directly affecting cash‑flow and tax‑planning outcomes.

Key Takeaways

• Rev. Proc. 2026‑17 permits withdrawing Sec. 163(j)(7) elections.
• Late election under Sec. 168(k)(7) can block bonus depreciation.
• H.R. 1 makes 100% bonus depreciation permanent.
• CFC group election revocation no longer bound by 60‑month rule.
• Effective March 18 2026, applies to election year.

Pulse Analysis

The business‑interest deduction under IRC §163(j) has long been a focal point for corporations seeking to balance financing costs with taxable income. Recent legislative action, encapsulated in H.R. 1 – the One Big Beautiful Bill Act – codified permanent 100 percent bonus depreciation and restored the ability to include depreciation and amortization when calculating the §163(j) limitation. This shift not only amplifies the depreciation shield but also reshapes the strategic calculus for firms that rely heavily on debt financing, prompting a wave of tax‑planning adjustments.

IRS Revenue Procedure 2026‑17 translates the statutory changes into practical guidance. Taxpayers may now withdraw previously made §163(j)(7) elections for real‑property, farming, or regulated‑utility trades within the year the election was filed, and subsequently file a late §168(k)(7) election to forego bonus depreciation on affected property classes. The procedural flexibility eases compliance burdens and offers companies a back‑door method to align their depreciation strategies with the new permanent bonus rate, potentially preserving interest‑deduction capacity.

The procedure also addresses controlled foreign corporation (CFC) groups, allowing revocation of the §1.163(j)‑7(e) election without observing the historic 60‑month limitation for periods beginning after December 31 2024. Multinational enterprises can therefore restructure foreign earnings and interest allocations more dynamically, enhancing global tax efficiency. As the effective date of March 18 2026 approaches, practitioners should review election timelines, model the impact on taxable income, and integrate the new options into broader capital‑allocation and financing strategies.
