The Affordable Care Act of 2010 included a provision requiring employers to report the cost of coverage under an employer-sponsored group health plan on the employee’s 2012 W-2.
However, employers issuing fewer than 250 W-2s will not need to include the cost of health care on W-2s for 2012. For these employers, the 2012 reporting is optional. And such reporting will not apply for future calendar years until the IRS publishes further guidance.
