Tuesday is the first Tax Day that thousands of married same-sex couples in New York can file joint taxes, and lawyers, activists and officials gathered outside the IRS center in Manhattan Monday to celebrate the change.
The new rules come as a result of last year's Supreme Court decision, which found part of the Defense of Marriage Act to be unconstitutional.
The case was brought on by New Yorker Edith Windsor.
Rep. Carolyn Maloney spoke about what the new laws mean for gay couples.
"There are about 179 provisions of the tax code that are affected by a person's marital status, 179 times our tax code discriminates against those who are denied the right to marry," Maloney said.
"This is the first time we've actually been able to take advantage of filing jointly, and we have found that it benefited us tremendously," said Randy Jones, a member of The Village People.
"This is just one more step into full equality, and what I mean by full equality is not just marriage equality in some states, but marriage equality in all states," said Eunic Ortiz, president of the Stonewall Democratic Club.
Because New York recognizes same-sex marriages, couples here can file both state and federal taxes as a married couple.
However, gay couples living in states that do not recognize same-sex marriage can only jointly file their federal returns.
