Defense of Marriage Act

Individuals who were in same-sex marriages may, but are not required to, file original or amended returns choosing to be treated as married for federal tax purposes for one or more prior tax years still open under the statute of limitations. Generally, the statute of limitations for filing a refund claim is three years from the date the return was filed or two years from the date the tax was paid, whichever is later. As a result, refund claims can still be filed for tax years 2010, 2011 and 2012. Some taxpayers may have special circumstances, such as signing an agreement with the IRS to keep the statute of limitations open, that permit them to file refund claims for tax years 2009 and earlier.
