"Two months after the Supreme Court struck down the Defense of Marriage Act, the Treasury Department on Thursday ruled that legally married same-sex couples will be treated as married for federal tax purposes.

The decision has a host of implications, even for same-sex married couples who now live in states that don't recognize same-sex marriage.

It affects how they will be treated in terms of federal income taxes, federal estate and gift taxes, the tax breaks they get for employer-sponsored health insurance and other benefits."
