Executive summary

Proposed regulations under section 250 would exclude income and gain from certain intellectual property transfers and sales of depreciable, amortizable or depletable property when calculating foreign-derived deduction-eligible income (FDDEI). For affected businesses, questions remain about how those exclusions would apply to losses, rebuilt equipment, assets used briefly as demonstrators or loaners, and contracts that combine standard software access with customized development.

Comments submitted by Oct. 5, 2026, can help the Treasury Department and the IRS understand how the proposed rules would operate in ordinary commercial settings. Businesses can provide value by documenting representative transactions, identifying where existing accounting and project-management systems do not align with the proposed classifications and proposing objective standards that could be administered consistently. Examples involving asset-sale losses, remanufactured equipment, incidental depreciable use and mixed software arrangements may help shape clearer final regulations and reduce uncertainty for taxpayers and examination teams.


Considerations for Comments on the Proposed FDDEI Regulations

New proposed regulations were issued on Aug. 20 clarifying certain aspects of the One Big Beautiful Bill Act (OBBBA) as it relates to FDDEI, specifically section 250(b)(3)(A)(i)(VII), which narrows the category of income eligible for the FDDEI deduction. At a high level, the regulations would generally exclude income and gain from certain transfers of intellectual property and certain sales of depreciable, amortizable and depletable assets.

Comments are requested before Oct. 5, 2026. Comments will be most useful if they focus on requesting additional guidance on how the rules operate in ordinary commercial settings.
