On December 20, Congress voted to pass a comprehensive tax reform bill (the “Act”), and the President signed the Act into law two days later. The Act represents the most significant reform of the U.S. tax code in over 30 years. This memorandum describes some of the important features of the legislation that will affect the taxation of infrastructure investors and investments, and highlights certain areas where the Act diverges from the earlier draft legislation. Most of the provisions described within this memorandum will be effective for tax years beginning after 2017.
