DOMA’s principal effect is to identify a subset of state-sanctioned marriages and make them unequal. The principal purpose is to impose inequality, not for other reasons like governmental efficiency. Responsibilities, as well as rights, enhance the dignity and integrity of the person. And DOMA contrives to deprive some couples married under the laws of their State, but not other couples, of both rights and responsibilities. By creating two contradictory marriage regimes within the same State, DOMA forces same-sex couples to live as married for the purpose of state law but unmarried for the purpose of federal law, thus diminishing the stability and predictability of basic personal relations the State has found it proper to acknowledge and protect. By this dynamic DOMA undermines both the public and private significance of state-sanctioned same-sex marriages; for it tells those couples, and all the world, that their otherwise valid marriages are unworthy of federal recognition. This places same-sex couples in an unstable position of being in a second-tier marriage. The differentiation demeans the couple, whose moral and sexual choices the Constitution protects, see
Lawrence,
539 U. S. 558, and whose relationship the State has sought to dignify. And it humiliates tens of thousands of children now being raised by same-sex couples. The law in question makes it even more difficult for the children to understand the integrity and closeness of their own family and its concord with other families in their community and in their daily lives.
Under DOMA, same-sex married couples have their lives burdened, by reason of government decree, in visible and public ways. By its great reach, DOMA touches many aspects of married and family life, from the mundane to the profound. It prevents same-sex married couplesfrom obtaining government healthcare benefits they would otherwise receive. See 5 U. S. C. §§8901(5), 8905. It deprives them of the Bankruptcy Code’s special protections for domestic-support obligations. See 11 U. S. C. §§101(14A), 507(a)(1)(A), 523(a)(5), 523(a)(15). It forces them to follow a complicated procedure to file their state and federal taxes jointly. Technical Bulletin TB–55, 2010 Vt. Tax LEXIS 6 (Oct. 7, 2010); Brief for Federalism Scholars as
Amici Curiae 34. It prohibits them from being buried together in veterans’ cemeteries. National Cemetery Administration Directive 3210/1, p. 37 (June 4, 2008).
For certain married couples, DOMA’s unequal effects are even more serious. The federal penal code makes it a crime to “assaul[t], kidna[p], or murde[r] . . . a member of the immediate family” of “a United States official, aUnited States judge, [or] a Federal law enforcement officer,”
18 U. S. C. §115(a)(1)(A), with the intent to influence or retaliate against that official, §115(a)(1). Although a “spouse” qualifies as a member of the officer’s “immediate family,” §115(c)(2), DOMA makes this protection inapplicable to same-sex spouses.
DOMA also brings financial harm to children of same-sex couples. It raises the cost of health care for familiesby taxing health benefits provided by employers to their workers’ same-sex spouses. See
26 U. S. C. §106; Treas. Reg. §1.106–1, 26 CFR §1.106–1 (2012); IRS Private Letter Ruling 9850011 (Sept. 10, 1998). And it denies or re-duces benefits allowed to families upon the loss of a spouseand parent, benefits that are an integral part of family security. See Social Security Administration, Social Security Survivors Benefits 5 (2012) (benefits available to a surviving spouse caring for the couple’s child), online at

DOMA divests married same-sex couples of the duties and responsibilities that are an essential part of married life and that they in most cases would be honored to accept were DOMA not in force. For instance, because it is expected that spouses will support each other as they pursue educational opportunities, federal law takes into consideration a spouse’s income in calculating a student’s fed-eral financial aid eligibility. See
20 U. S. C. §1087nn(b). Same-sex married couples are exempt from this requirement. The same is true with respect to federal ethics rules. Federal executive and agency officials are prohibited from “participat[ing] personally and substantially” in matters as to which they or their spouses have a financial interest.
18 U. S. C. §208(a). A similar statute prohibits Senators, Senate employees, and their spouses from accepting high-value gifts from certain sources, see
2 U. S. C. §31–2(a)(1), and another mandates detailed financial disclosures by numerous high-ranking officials and their spouses. See 5 U. S. C. App. §§102(a), (e). Under DOMA, however, these Government-integrity rules do not apply to same-sex spouses.
