Yes. Same-sex marriage is legal throughout the United States as a matter of federal law. Two things make that true: the Supreme Court’s 2015 decision in Obergefell v. Hodges, which held that the Constitution guarantees same-sex couples the right to marry, and the Respect for Marriage Act of 2022, a federal statute requiring the national government and every state to recognize valid same-sex marriages.1Justia U.S. Supreme Court Center. Obergefell v. Hodges, 576 U.S. 644 (2015)2Congress.gov. H.R.8404 – Respect for Marriage Act Together they mean same-sex married couples receive the same federal benefits, tax treatment, and interstate recognition as any other married couple.
The Constitutional Ruling: Obergefell v. Hodges
In June 2015, the Supreme Court ruled that the Fourteenth Amendment requires every state to issue marriage licenses to same-sex couples and to recognize same-sex marriages performed in other states.1Justia U.S. Supreme Court Center. Obergefell v. Hodges, 576 U.S. 644 (2015) The Court grounded that holding in both the Due Process Clause, treating marriage as a fundamental liberty, and the Equal Protection Clause, which forbids denying same-sex couples a right granted to opposite-sex couples without justification.
The decision struck down every state law and state constitutional amendment that had limited marriage to opposite-sex couples. Since then, same-sex couples have been able to marry in every state on the same terms as any other couple.
The Federal Statute: The Respect for Marriage Act
In 2022, Congress passed the Respect for Marriage Act, which rewrote the federal definition of marriage.2Congress.gov. H.R.8404 – Respect for Marriage Act For purposes of any federal law, rule, or regulation, a person is considered married if the marriage is between two individuals and was valid in the jurisdiction where it took place.3Office of the Law Revision Counsel. 1 U.S.C. 7 – Marriage The Act also requires every state to recognize a marriage that was valid where it was performed, regardless of the sex, race, ethnicity, or national origin of the spouses.4Office of the Law Revision Counsel. 28 U.S.C. 1738C – Certain Acts, Records, and Proceedings and the Effect Thereof
The statute replaced the earlier Defense of Marriage Act, which had defined marriage federally as a union of one man and one woman and had allowed states to ignore same-sex marriages from other jurisdictions.5Library of Congress. Specifically Applicable Federal Law on Full Faith and Credit Clause Both of those provisions are gone.
What Federal Recognition Gets You
Federal recognition is not symbolic. It controls tax filing, retirement and survivor benefits, health coverage, immigration sponsorship, and hundreds of other rights and programs tied to marital status.
Federal Taxes
The IRS recognizes same-sex marriages for all federal tax purposes, including filing status, the standard deduction, IRA contributions, and credits such as the earned income tax credit and the child tax credit.6Internal Revenue Service. Same-Sex Marriages Now Recognized for Federal Tax Purposes Married same-sex couples file as married filing jointly or married filing separately.
The IRS applies a place-of-celebration rule: if the marriage was valid where it was performed, the IRS treats the couple as married regardless of where they now live, and the same rule applies to marriages performed abroad.7Internal Revenue Service. Revenue Ruling 2013-17
Social Security
The Social Security Administration treats same-sex spouses the same as opposite-sex spouses for benefit calculations. A surviving spouse may qualify for survivor benefits at age 60 (or 50 with a disability) if the marriage lasted at least nine months before the death and the survivor has not remarried before age 60, with an alternate path for survivors caring for the deceased spouse’s child.8Social Security Administration. Who Can Get Survivor Benefits
Because many couples were legally barred from marrying before 2015, the SSA follows settlement agreements in Ely v. Saul and Thornton v. Commissioner of Social Security directing it to consider whether unconstitutional state bans prevented an earlier marriage. If you would have met the nine-month requirement but for the ban, the agency may still approve the claim.9Social Security Administration. Survivors Benefits for Same-Sex Partners and Spouses
Federal Employee and Veterans Benefits
Same-sex spouses of federal employees are eligible for every benefit available to opposite-sex spouses, including Federal Employees Health Benefits enrollment, Federal Employees’ Group Life Insurance, and retirement beneficiary designations, regardless of the employee’s state of residence.10U.S. Office of Personnel Management. I Have a Same Sex Marriage Children of same-sex marriages, including stepchildren, are treated identically to children of opposite-sex marriages.
The Department of Veterans Affairs recognizes same-sex spouses for survivors pension, dependency and indemnity compensation, and related benefits. The VA will consider a surviving spouse’s relationship as satisfying marriage-duration requirements where there is evidence the couple maintained a committed, marriage-like relationship and would have married sooner if state law had permitted it.11Federal Register. Instruction of the Secretary and General Policy Statement on the Administration of Benefits for Particular Same-Sex Surviving Spouses
Immigration
Same-sex marriages are treated identically to opposite-sex marriages for immigration. A U.S. citizen or lawful permanent resident can sponsor a same-sex spouse for a green card through an I-130 petition on the same terms as any other spousal petition, provided the marriage was valid where performed, entered in good faith, and both parties were free to marry.12U.S. Citizenship and Immigration Services. Volume 6, Part B, Chapter 6 – Spouses Same-sex couples are also eligible for the K-1 fiancé visa.13U.S. Department of State. Nonimmigrant Visa for a Fiance(e) (K-1) USCIS uses the place-of-celebration rule, so a same-sex marriage performed abroad is recognized if it was legal in the country where it took place.14U.S. Citizenship and Immigration Services. Volume 12, Part G, Chapter 2 – Marriage and Marital Union for Naturalization
Recognition Across State Lines
Under the Respect for Marriage Act, a same-sex marriage valid where performed must be recognized in every other state.4Office of the Law Revision Counsel. 28 U.S.C. 1738C – Certain Acts, Records, and Proceedings and the Effect Thereof The legal rights that come with marriage — hospital visitation, inheritance, medical decision-making, property rights — travel with you across state lines. No state can refuse to honor your marriage based on the sex of either spouse. Divorce works the same way: every state must grant divorces to same-sex couples on the same terms as opposite-sex couples, though standard state residency requirements still apply before you can file.
Parental Rights: One Area That Still Needs Attention
In Pavan v. Smith (2017), the Supreme Court held that states must list both same-sex spouses on a child’s birth certificate under the same conditions they would list both opposite-sex spouses.15Justia U.S. Supreme Court Center. Pavan v. Smith, 582 U.S. ___ (2017) Even so, the practical landscape for parental rights is uneven. States apply the marital presumption — that a child born to a married couple is presumed to be the child of both spouses — differently to same-sex couples, and some courts have held that parentage statutes written before Obergefell do not automatically cover the non-biological parent. Many family law attorneys recommend a second-parent or confirmatory adoption for the non-biological parent, because an adoption order is recognized in every state and holds up if the family moves, travels internationally, or faces a custody dispute.
What Happens If Obergefell Is Overturned
Congress passed the Respect for Marriage Act partly in response to Justice Clarence Thomas’s concurring opinion in Dobbs v. Jackson Women’s Health Organization, which suggested the Court should reconsider decisions grounded in substantive due process, including Obergefell. It is worth being clear about what the statute does and does not do.
The Respect for Marriage Act requires the federal government to recognize any same-sex marriage that was valid where performed, and it requires every state to recognize such marriages from other states.3Office of the Law Revision Counsel. 1 U.S.C. 7 – Marriage4Office of the Law Revision Counsel. 28 U.S.C. 1738C – Certain Acts, Records, and Proceedings and the Effect Thereof It does not independently require states to issue new marriage licenses to same-sex couples. That requirement comes from Obergefell. If the Court ever overturned that decision, marriage licensing would become a state-by-state question again, but existing marriages and marriages performed in states that continued to issue licenses would keep their federal and interstate recognition under the statute.
