Del. Eleanor Holmes Norton, D-D.C., predicted Friday that the Treasury Department’s announcement that couples in legal gay marriages will be treated as married couples when filing federal income taxes could be an economic boon to the District.

“We in D.C. probably will see more and more same-sex couples from surrounding states, like Virginia, West Virginia, Pennsylvania, and North Carolina, where same-sex marriage is not yet legal, coming to the nation’s capital to get married so they can now receive the same federal tax benefits back home,” Norton said in a statement. “Thus, this tremendous step forward for gay couples will likely bring economic by products to our city, simply because we acted on our beliefs in equality for all citizens.”

The city began licensing same-sex marriage in March 2010.

Norton said the Treasury Department’s ruling “does justice to same-sex marriage couples, at least for federal tax purposes.”

She also applauded the “quick ruling” from the department in the wake of the Supreme Court’s decision to overturn the Defense of Marriage Act.

The Supreme Court issued its decision in United States v. Windsor on June 26, and Treasury Secretary Jacob L. Lew announced the department’s interpretation on Thursday.
