Course Materials

This course will provide tax advisers serving clients with controlled foreign corporations (CFCs) with a detailed and practical guide to the new Section 163(j) business interest deduction limitation rules--part of the 2017 tax reform law--as they apply to foreign corporations and their U.S. shareholders. The panel will discuss the CFC group election and potential benefits of making the CFC group election, as well as detail the mechanics of calculating adjusted taxable income (ATI) for CFCs and their U.S. shareholders.


The new Section 163(j) limitation on business interest deductibility creates serious tax consequences for many U.S. and foreign taxpayers. The Section 163(j) proposed regulations provide that the Section 163(j) limitation applies to CFCs, generally treating CFCs in the same manner as domestic corporations, but with a couple of significant distinctions.

One such key difference is the availability of a "CFC group election" allowing certain commonly controlled CFCs to limit the amount of business interest expense of a CFC group member subject to the Section 163(j) limitation in certain situations. If a CFC group election is in effect, Section 163(j) proposed regulations also permit the “rolling up” of excess taxable income through the tiers of ownership in certain situations.

Listen as our experienced panel provides a thorough and practical guide to the new Section 163(j) business interest deduction limitation as they impact CFCs and their U.S. shareholders.
