Section 250 After the OBBBA: What Corporations Need to Know
by
Treasury has never issued definitive guidance on how the Section 250 deduction interacts with Sections 163(j) and 172, and with OBBBA Section 250 changes now in effect, the stakes for domestic corporations are higher than ever. Since the Tax Cuts and Jobs Act introduced Section 250 in 2017, domestic corporations claiming the foreign-derived intangible income (FDII) deduction, now renamed foreign-derived deduction eligible income (FDDEI) under the One Big Beautiful Bill Act, have faced a persistent and unresolved question: how does Section 250 interact with other provisions that also limit deductions based on taxable income?
Section 250, Section 163(j), and Section 172: The Interaction Problem
The problem is circular. The Section 250 deduction depends on taxable income, which itself depends on the Section 163(j) business interest limitation and the Section 172 NOL deduction. Each provision’s output is an input for the others, and the Code does not resolve the conflict.
The 2019 Ordering Rule (Treasury Reg. § 1.250(a)-1)
Treasury attempted to address this in 2019 with a five-step sequential framework, but withdrew it in the 2020 Final Regulations without a replacement. The reserved paragraph at Treas. Reg. § 1.250(a)-1(c)(5)(ii) has sat empty ever since. In the interim, taxpayers are permitted to use “any reasonable method,” including the 2019 ordering rule or simultaneous equations, applied consistently from 2021 forward.
Which Method Should a Corporation Use After OBBBA?
The method chosen is not a technical formality. Because unused Section 250 deductions are permanently lost while disallowed business interest and NOL carryforwards survive into future years, the choice directly affects how much deduction benefit a corporation keeps versus merely defers. The 2019 ordering rule generally favors Section 250, while simultaneous equations maximize total deductions but may allocate more to interest at Section 250’s expense.
Tax Controversy Risk and Documentation
For corporations working through the OBBBA Section 250 changes, the deduction rate is now permanently set at 33.34% of FDDEI and 40% of net CFC tested income. The depreciation and amortization add-back is restored for ATI under Section 163(j), but Subpart F and GILTI inclusions are now excluded from ATI, a change that could tighten the 163(j) ceiling for corporations with significant foreign income. Interest expense is also statutorily excluded from the FDDEI expense allocation, resolving one longstanding controversy while others remain open.
