The entire Senate Democratic Caucus on Thursday introduced a bill that would take gender-specific references to marriage out of the tax code.

The legislation follows the Supreme Court's ruling in 2015 that legalized same-sex marriage nationwide, as well as Treasury Department guidance finalized last year that allows same-sex married couples to file joint federal tax returns.

The bill is not the first measure relating to taxes and same-sex marriages that Democrats have introduced in recent weeks.

Last month, a group of House and Senate Democrats introduced legislation that would allow same-sex couples that legally married prior to 2013 — when the Supreme Court overturned a key provision in the Defense of Marriage Act that defined marriage as between a man and a woman — to amend old tax returns to file jointly.
