Sen. Elizabeth Warren, D-Mass., reintroduced a bill on the campaign trail this week, which could mean $57 million in tax refunds for married LGBT couples.

The Refund Equality Act, which was originally introduced in 2017, would allow LGBT couples who were married prior to the 2013 Supreme Court strike-down of the Defense of Marriage Act in U.S. v. Windsor to amend tax returns from the time that they were married. Prior to 2013, 10 states had legalized same-sex marriage, but were required to file their federal taxes as individuals.

Following the 2013 Supreme Court's decision, married same sex couples from those 10 states were permitted to change their previous tax returns from individual to joint, which entitled them to some federal tax relief. However, the tax return amendments were only permitted for the previous three years. The Refund Equality Act would remove those time limits.

According to a report released this week from the Joint Committee on Taxation, same sex couples married prior to 2013 could potentially be eligible for $57 million if permitted to file jointly from the time they were married.

In a statement regarding the reintroduction of the Refund Equality Act, Warren said, "The federal government forced legally married same-sex couples in Massachusetts to file as individuals and pay more in taxes for almost a decade. It is only right that we change this tax code to make it fairer for all."

It wasn’t until marriage equality became law that gay & lesbian couples could jointly file tax returns—so they paid more in taxes. Our government owes them more than $50M for the years our discriminatory tax code left them out. We must right these wrongs. https://t.co/OZQcfVilSs — Elizabeth Warren (@ewarren) June 23, 2019

Democratic Rep. Judy Chu, Calif., introduced companion legislation last week called the PRIDE Act of 2019 which would alter the federal tax code that currently prevents married couples from amending their returns beyond the previous three years. The change would apply only to same sex couples married prior to U.S. v. Wind.
