Politico and other media outlets are reporting the Treasury Department and IRS announced Thurs., Aug. 29, legally married same-sex couples will be treated as married couples for federal tax purposes. This tax treatment will apply even if a couple lives in a state that does not recognize same-sex marriage so long as they were married in a state that does. The guidance, stemming from the Supreme Court ruling this summer that overturned the Defense of Marriage Act, says same-sex couples can begin filing tax returns as "married filing jointly" or "married filing separately" for the 2013 tax year.
