For a long time same sex couples couldn’t get married and get the benefits that many other married couples get for their taxes. I read an article that explains these benefits perfectly.
On August 29, the U.S. Department of the Treasury and the Internal Revenue Service (IRS) released guidance clarifying that same-sex couples who are legally married in jurisdictions or countries that recognize their marriages will be treated as married for all federal tax purposes, regardless of whether the same-sex couple resides in a state or jurisdiction that recognizes same-sex marriages. This is commonly called a “state of celebration” approach to federal taxation issues. Note that the IRS guidance has no impact on the federal tax treatment of civil unions, domestic partnerships, or other employer-created variations of domestic partnerships, nor does it impact the state tax treatment for any same-sex relationships in states that do not recognize same-sex marriages, including same-sex marriages entered into in other jurisdictions.
