The Obama administration will delay a key requirement of the president's 2010 health law, bowing to pressure from businesses who have complained about a mandate in the law that employers with more than 50 full-time employees provide health benefits or pay a fine.

The Treasury Department said this afternoon the delay is designed to help provide a smoother transition due to complex reporting requirements involved. The department will do real-world testing of the reporting system on a voluntary basis with employers.  

That requirement will be not go into effect until 2015, instead of 2014 as the Affordable Care Act originally outlined, according to an announcement from the Treasury Department.
