Yes. Gay marriage is legal in all 50 states, the District of Columbia, and every U.S. territory. Two separate legal protections now sit on top of each other: the Supreme Court’s 2015 decision in Obergefell v. Hodges, which made same-sex marriage a constitutional right, and the Respect for Marriage Act, which Congress passed in 2022 to lock in federal recognition and interstate recognition by statute. Every state must issue marriage licenses to same-sex couples and must recognize same-sex marriages performed anywhere else in the country.
What Obergefell Established
In Obergefell v. Hodges, the Supreme Court held that the Fourteenth Amendment’s Due Process and Equal Protection Clauses guarantee same-sex couples the right to marry on the same terms as opposite-sex couples.1Justia. Obergefell v. Hodges, 576 U.S. 644 (2015) The ruling did two concrete things: it required every state to issue marriage licenses to same-sex couples, and it required every state to recognize same-sex marriages lawfully performed elsewhere. It struck down every state ban and constitutional amendment prohibiting these unions and extended the full range of marital benefits, including adoption rights, health-care access, inheritance, taxation, Social Security spousal benefits, and recognition as next of kin.2Legal Information Institute. Obergefell v. Hodges
As of 2026, Obergefell remains binding law, and the Court has not agreed to reconsider it.
What the Respect for Marriage Act Added
Obergefell is a court decision, and a future Court could revisit it. That possibility became more concrete in 2022, when Justice Thomas wrote a concurrence in Dobbs v. Jackson Women’s Health Organization suggesting Obergefell should be reconsidered. Congress responded by passing the Respect for Marriage Act (Public Law 117-228), signed into law on December 13, 2022.3Congress.gov. Public Law 117-228 – Respect for Marriage Act
The Act does three things:
- It repeals the part of the Defense of Marriage Act (28 U.S.C. § 1738C) that had let states refuse to recognize out-of-state same-sex marriages.3Congress.gov. Public Law 117-228 – Respect for Marriage Act
- It amends 1 U.S.C. § 7 so that any marriage between two individuals valid in the state where it was performed must be recognized by the federal government.4Office of the Law Revision Counsel. 1 USC 7 – Marriage
- It requires states to recognize marriages valid where performed, regardless of the spouses’ sex or race, and authorizes the Attorney General to bring a civil action against violators.3Congress.gov. Public Law 117-228 – Respect for Marriage Act
The practical significance is as a safety net. If the Supreme Court ever overturned Obergefell, same-sex marriage would not automatically become illegal: the federal government would still have to recognize existing marriages, and states would still have to honor marriages performed in states that continue to allow them. The Act would not, however, force a state to issue new licenses if it chose to stop. That is why the constitutional protection of Obergefell remains the more complete shield.
Recognition Across State Lines
Both Obergefell and the Respect for Marriage Act independently require every state to recognize a same-sex marriage performed elsewhere.1Justia. Obergefell v. Hodges, 576 U.S. 644 (2015) A couple married in Massachusetts keeps their full legal status when they move to Texas. Parental rights, property ownership, health-care decision-making authority, and every other incident of marriage travel with them.
Recognition outside the United States is a different question. No international treaty guarantees automatic recognition of U.S. same-sex marriages abroad, and many countries do not recognize them.
Federal Benefits That Follow
A valid same-sex marriage triggers the same federal benefits and obligations as any other marriage across more than a thousand statutes. The most consequential:
Tax Filing
Same-sex married couples must file federal income taxes as either married filing jointly or married filing separately. They cannot use single or head-of-household status.5Internal Revenue Service. Same-Sex Marriages Now Recognized for Federal Tax Purposes The IRS looks at whether the marriage was valid where it was performed, not where the couple currently lives.
Social Security Survivor Benefits
A surviving same-sex spouse qualifies for Social Security survivor benefits on the same terms as any other surviving spouse. The general rule is a nine-month marriage before the worker’s death, but the Social Security Administration will consider circumstances where a couple was prevented from marrying that long because same-sex marriage was illegal in their state, and may waive the duration requirement.6Social Security Administration. Survivors Benefits for Same-Sex Partners and Spouses Anyone previously denied for this reason can ask the SSA to reopen the claim.
Immigration
Same-sex spouses are eligible for marriage-based green cards on the same evidentiary terms as any other couple: shared finances, cohabitation records, and other proof of a bona fide marriage. A marriage valid where it was performed satisfies the federal requirement under 1 U.S.C. § 7 even if the couple now lives in a different state or abroad.4Office of the Law Revision Counsel. 1 USC 7 – Marriage
Parentage and Birth Certificates
In 2017, the Supreme Court held in Pavan v. Smith that states cannot deny married same-sex couples recognition on their children’s birth certificates if they provide that recognition to married opposite-sex couples. The ruling was grounded in the “constellation of benefits” that Obergefell said states must extend equally.7Justia. Pavan v. Smith, 582 U.S. (2017)
A birth certificate listing creates a presumption of parentage, not an ironclad legal determination. Family law attorneys widely recommend that the non-biological parent in a same-sex marriage also obtain a second-parent adoption or a court judgment of parentage. A court judgment receives full faith and credit in every state; a birth certificate alone can be challenged. This matters most for families who may relocate to a state with less favorable case law, or for couples who used donor sperm, egg donation, or a gestational carrier.
Where the Right Doesn’t Reach
Marriage equality applies to civil marriage. No religious institution is required to perform or host a same-sex wedding ceremony. The Respect for Marriage Act makes this explicit: nonprofit religious organizations cannot be compelled to provide services, facilities, or goods for the solemnization or celebration of a marriage, and the Act cannot be used to strip a religious organization’s tax-exempt status or deny it grants and contracts over its views on marriage, so long as the benefit in question does not arise from a marriage.3Congress.gov. Public Law 117-228 – Respect for Marriage Act
For-profit businesses that serve the general public sit on different legal ground. Whether a commercial wedding vendor can refuse service to a same-sex couple depends primarily on state and local public accommodation laws, which vary widely. No federal public accommodation statute currently prohibits sexual-orientation discrimination in all commercial settings, and the Respect for Marriage Act does not address the question.
Old State Bans Still on the Books
Dozens of states still have constitutional amendments or statutes defining marriage as between a man and a woman. These provisions are unenforceable after Obergefell and the Respect for Marriage Act, but they have not been formally repealed. Removing a state constitutional amendment requires the state’s own amendment process, which typically involves legislative approval and a public vote. Some states have begun that work; Virginia, for instance, has a ballot measure to remove its ban. Others have made no effort.
These dead-letter provisions have no current effect on anyone’s ability to marry or have a marriage recognized. They would only matter in the remote scenario where both Obergefell was overturned and the Respect for Marriage Act was repealed.
