The Affordable Care Act (ACA), which was signed into law in March 2010, put in place comprehensive health coverage reform, with effective dates spread out over a period of four years and beyond. Some of ACA’s reform initiatives are already in effect for employers and their group health plans, such as the Form W-2 reporting requirement for large employers and the requirement for non-grandfathered health plans to cover certain preventive care services without cost-sharing. Many of ACA’s key reform initiatives will become effective in 2014 . Key ACA reforms that will affect employers in 2014 include health plan design changes, increased wellness program incentives, a new reinsurance fee, the employer “pay or play” mandate, and additional reporting requirements. To prepare for this next phase of ACA reform, employers should review upcoming requirements and make sure they have a compliance strategy in place.
