The IRS has a website on which it provides an overview of this provision and related information, such as a chart of W-2 reporting of employer-sponsored coverage requirements by coverage type. An IRS Q&A provides further information on the implementation of this section.
Specific IRS guidance is available at Notice 2010-69, making the reporting requirement optional for all employers for 2011 W-2 forms; Notice 2011-28, providing additional transitional relief for certain smaller employers; and Notice 2012-9, reaffirming and clarifying earlier guidance for employers subject to the reporting requirement for 2012 W-2s.
On Jan. 22, 2014 the IRS posted information noting that while employers generally are eligible for transition relief until final guidance is released (details), employer-sponsored coverage costs may appear on 2013 W-2s, as stipulated by the ACA.
