In what was a surprising development to many, after a hotly contested election in which the political control of the United States Senate was shifted to the Republican Party and the Republican representation increased in the United States House of Representatives, the United States Congress passed and the President on December 19, 2014 signed, the Tax Increase Prevention Act of 2014, Pub.

No. 113-295, the so-called “extenders bill.” What many found surprising was that the one-year extension of provisions, through December 31, 2014, was made retroactive to January 1, 2013, which meant that the 2014 legislation had an effective life of 12 days to boost the economy, which was the apparent purpose of many of the provisions. The uncertainty existing throughout 2014 with respect to the provisions in the 2014 bill, was renewed on January 1, 2015. This article summarizes the major tax provisions of widespread interest.
