Employer-Sponsored Health Coverage
The Affordable Care Act requires employers to report the cost of health coverage under an employer-sponsored group health plan. The amount of the health care coverage will be reported in Box 12 of the W-2, with Code DD to identify the amount. This amount should include both the employer and the employee health coverage expenses. (In AccountEdge, map the employer expense and the employee deduction to one of the box 12 entries.)
AccountEdge was updated in release 16.1.12 (AccountEdge Pro 2012) and 17.0.4 (AccountEdge Pro 2013) to accommodate this requirement.
