2013 was a big year for same-sex marriage, and this year’s tax filing proves it. Same-sex couples married in any of the 17 states that have legalized gay marriage can choose to file joint federal tax returns or married separate returns regardless of whether their current state of residence recognizes the marriages.
Same-sex couples can also file amended joint tax returns as far back as 2010.
However, this also means same-sex couples may hit the so-called marriage penalty, in which they may face fewer deductions and higher taxes when pooling incomes together.
