Rights and responsibilities of marriages in the United States

According to the United States Government Accountability Office (GAO), there are 1,138 statutory provisions in which marital status is a factor in determining benefits, rights, and privileges. These rights were a key issue in the debate over federal recognition of same-sex marriage. Under the 1996 Defense of Marriage Act (DOMA), the federal government was prohibited from recognizing same-sex couples who were lawfully married under the laws of their state. The conflict between this definition and the Due Process Clause of the Fifth Amendment to the Constitution led the U.S. Supreme Court to rule DOMA unconstitutional on June 26, 2013, in the case of United States v. Windsor.

Prior to the enactment of DOMA, the GAO identified 1,049 federal statutory provisions in which benefits, rights, and privileges are contingent on marital status or in which marital status is a factor. An update was published in 2004 by the GAO covering the period between September 21, 1996 (when DOMA was signed into law), and December 31, 2003. The update identified 120 new statutory provisions involving marital status, and 31 statutory provisions involving marital status repealed or amended in such a way as to eliminate marital status as a factor.

On June 26, 2015, in the case of Obergefell v. Hodges, the Supreme Court ruled that marriage is a fundamental right guaranteed to all citizens, and thus legalized same-sex marriage nationwide.

There are some laws that either benefit or penalize married couples over single people, depending upon their own circumstances:

In addition, community-property states frequently have forms of ownership that allow a full basis step-up on one's own share of community property on the death of a spouse (in addition to the normal step-up on spouse's assets).

Following the 2004 GAO report at least one bill, the Uniting American Families Act, has been proposed to attempt to remedy some of the differences in rights between same-sex partnerships and marriages.
