Following the Supreme Court’s 2013 decision in U.S. v. Windsor (in which the Court held that Section 3 of the federal Defense of Marriage Act (“DOMA”) was unconstitutional), one of the questions facing sponsors of tax-qualified retirement plans was whether the plans were required to recognize same-sex spouses on a retroactive basis for purposes of entitlement to spousal benefits.  The IRS answered that question in Notice 2014-19, in which it stated that, for tax-qualification purposes, such plans are required to treat same-sex marriages in the same manner as opposite-sex marriages effective as of June 26, 2013 (the date of the Windsor decision). The IRS also clarified that plans could be amended to recognize same-sex marriages prior to that date, but such earlier recognition was not required for qualification purposes.

Last week, the Internal Revenue Service (IRS) issued Notice 2015-86, providing guidance on the application of the U.S. Supreme Court’s decision in Obergefell v. Hodges to qualified retirement plans and health and welfare plans, including cafeteria plans.  Importantly, and as expected, the IRS comments in the Notice that it does not anticipate that Obergefell will have a significant impact on the application of federal tax law to employee benefit plans.

On October 21, 2015, the IRS issued proposed regulations to clarify the treatment of same-sex spouses for federal tax purposes. By way of background, in 2013, the United States Supreme Court held in United States v. Windsor that the portion of the Defense of Marriage Act defining marriage as being between opposite-sex partners was unconstitutional.
