On July 28, 2020, the Treasury Department released final regulations with guidance on applying the limitations on the deductibility of business interest expense (BIE) under IRC Section 163(j) (the Final Regulations), which was significantly modified by the Tax Cuts and Jobs Act (TCJA) and then temporarily modified by the Coronavirus Aid, Relief, and Economic Security Act (CARES Act). The Final Regulations provide guidance on what constitutes interest for purposes of the limitation, how to calculate the limitation, which taxpayers and trades or business are subject to the limitation, and how the limitation applies in certain contexts (e.g., consolidated groups). The final regulations were published in the Federal Register on September 14, 2020 and contain minor editorial changes. In response to questions from taxpayers and practitioners, the final regulations published in the Federal Register clarify that taxpayers may rely on the final regulations for any taxable year beginning after December 31, 2017, provided that certain conditions are met.
