On March 13, the United States Senate voted on several remaining amendments to the Moving Ahead for Progress in the 21st Century, or the MAP-21 Act (S. 1813). Included in those discussions were Sen. Menendez Amendment No. 1782 which amongst other things would have modified several renewable energy tax credits, Sen. Stabenow Amendment No. 1812 which proposed to extend certain expiring renewable tax credits relating to energy, and Sen. Roberts Amendment No. 1826 which proposed to extend the New Markets Tax Credit program for one year. All three of these amendments were rejected by the Senate. The renewable energy and NMTC amendments were tied to controversial and partisan language pertaining the Keystone XL pipeline, which ultimately eliminated their political viability. The Senate will continue to consider S. 1813; the bill is expected to pass the full Senate and will move on to the House of Representatives for consideration. It is unlikely that the House will consider additional tax extenders in their version of the bill.
