Following last summer’s Supreme Court decision in U.S. v. Windsor invalidating Section 3 of the Defense of Marriage Act (DOMA), the federal government began recognizing same-sex couples nationwide for the first time. The majority of federal benefits and programs recognize couples regardless of where they live – employing a “state of celebration” standard. This standard looks to the laws of the state where the couple was married to determine the validity of their marriage. In practice, this has provided expansive recognition for legally married same-sex couples nationwide — including for federal tax purposes.
In response to the Windsor decision, the IRS published revenue ruling 58-66 implementing a state of celebration standard for federal tax purposes and applying the generally applicable statute of limitations for requesting a refund to same-sex couples who were legally married and would have been recognized under IRS policy but for DOMA. This standard statute of limitations provides all taxpayers with an option to amend a tax return up to three years after filing. This revenue ruling therefore retroactively recognizes same-sex married couples who were legally married but were required to file as individuals because of DOMA beginning in 2010.
