Doug McHoney (PwC’s International Tax Services Global Leader) is joined by Rebecca Lee (WNTS ITS Partner) in PwC’s Washington, DC studio for the 140th (and Rebecca’s) episode of the Cross-Border Tax Talks podcast. Rebecca, a frequent guest on the podcast, specializes in financial transactions and digital assets. Doug and Rebecca discuss the history and intent of Section 987, which is generally to address the taxation of foreign exchange gains/losses from a foreign branch operating in a different functional currency than its home office. The rules started out relatively simply at three sentences, but since enactment we’ve received 100s of pages of regulations. Doug and Rebecca discuss how the layers of complication led to confusion and concerns over policy and administrability. This background is critical to understanding the challenges companies are facing today with the November 2023 proposed regulations. Doug and Rebecca dissect and analyze the 250-page package, what new elements and limitations they introduce, and what this means for affected companies, including industries like banking and insurance. They close the discussion with how the effective dates work and why the operation of these rules may have surprising results.
