The 2.3% medical device tax imposed by the Affordable Care Act (ACA; P.L. 111-148) in 2010 was one of a number of additional revenue-raising provisions to finance health reform. This tax, which took effect in January 2013, is projected to collect approximately $38 billion of excise tax revenues over the next 10 years, resulting in $29 billion of net revenues, after accounting for offsets from other taxes.
