Same-Sex Marriage and Federal Tax Law After DOMA
This paper examines the federal and state tax implications of same-sex marriage in the United States, tracing the legal landscape from the enactment of the Defense of Marriage Act (DOMA) in 1996 through the landmark 2013 Supreme Court ruling in United States v. Windsor. It analyzes how the Windsor decision — which declared Section 3 of DOMA unconstitutional — compelled the IRS to recognize same-sex marriages for federal tax purposes and prompted numerous states to revise their own tax laws. The paper reviews key cases, including Mueller v. Comm'r, Merrill v. Comm'r, and Gill v. Office of Personnel Management, to illustrate the evolution of tax treatment for same-sex couples and the ongoing tension between federal mandates and state-level recognition.

What makes this paper effective
- Grounds legal analysis in specific statutory language, quoting directly from DOMA, the U.S. Constitution, and IRS rulings to support each claim.
- Uses a chronological-to-thematic structure, moving from historical background through landmark case law to present-day state variation, giving readers a coherent narrative arc.
- Balances federal and state perspectives, demonstrating how a single Supreme Court decision created divergent outcomes across jurisdictions.
Key academic technique demonstrated
The paper demonstrates case-law synthesis — selecting multiple court decisions (Windsor, Mueller, Merrill, Gill) and weaving them into a unified argument about the unconstitutionality of DOMA's tax provisions. Rather than treating each case in isolation, the author uses each ruling to build incrementally toward the conclusion that denying tax benefits to same-sex couples violates equal-protection principles.
Structure breakdown
The paper opens with definitional and historical context (common-law marriage rulings, the 16th Amendment, DOMA's enactment), then devotes a section to the constitutional challenge culminating in Windsor. A central analytical section surveys how federal and state governments adapted their tax codes post-Windsor, illustrated with jurisdiction-by-jurisdiction detail. A fourth section reviews individual taxpayer cases before the Tax Court. The conclusion ties all threads together, framing continued resistance to same-sex marriage recognition as a potential violation of the Bill of Rights.
Introduction
Same-sex marriage refers to a legally recognized union between two persons of the same sex. In other words, a same-sex partner is a man legally married to another man, or a woman legally married to another woman. Because same-sex marriage is a relatively recent development in the United States, the federal government has faced challenges in handling the tax issues of same-sex individuals who enter into marriage. The IRS ruling 58-66, published in 1958-1 C.B. 60, determines the tax treatment of individuals who have entered into a common-law marriage. Under state law as administered by federal income tax law, the IRS acknowledges that it recognizes an individual's marital status.
Under IRS Ruling 58-66, the Service states that a couple will be treated as married for federal income tax filing purposes, and the IRS applied this ruling for over 50 years (Internal Revenue Service, 2014).
Article 1, Section 8 of the United States Constitution provides: "The Congress shall have Power To lay and collect Taxes, Duties, Imposts and Excises…; but all Duties, Imposts and Excises shall be uniform throughout the United States" (Trisha, 2013, p. 269).
In 1909, Congress passed the 16th Amendment, which empowered Congress to collect taxes from different sources without regard to enumeration or census. The Revenue Act of 1913 imposed a tax on corporate and individual net income. When practitioners refer to tax law, they most commonly cite the Tax Reform Act of 1986, also known as the Internal Revenue Code of 1986. Under the Tax Reform Act of 1986, a married couple may file taxes jointly or separately.
In the United States, most married couples file income taxes jointly; however, there are cases where a married couple may file separately if one spouse does not agree to a joint return. The married couples recognized by law were defined as one man and one woman legally married in the United States, and these couples were entitled to file joint tax returns. However, many same-sex couples also sought to file joint income tax returns, which many states consequently denied. Similarly, many same-sex partners sought to enjoy the same tax-return benefits available to opposite-sex couples.
In response to this situation, President Clinton signed the Defense of Marriage Act (DOMA) into law in 1996, directing the federal government not to recognize same-sex marriages. The law defined the term spouse as a union between two individuals of the opposite sex — either a husband or a wife. Section 3 of DOMA defined legal marriage as a legal union between a man and a woman serving as husband and wife. Section 2(a) of the Act states:
"No state, territory, or possession of the U.S., or Indian tribe, shall be required to give effect to any public act, record, or judicial proceeding of any other State, territory, possession, or tribe respecting a relationship between persons of the same sex that is treated as a marriage under the laws of such other State, territory, possession, or tribe, or a right or claim arising from such relationship" (Wald, 2013, p. 273).
However, DOMA has faced sustained criticism over the years. President Obama directed the Justice Department to stop defending Section 3 of DOMA. Following public criticism, the Senate Judiciary Committee voted to repeal DOMA in 2011. In 2013, the Internal Revenue Service ruled that same-sex couples who are legally married in the United States would be treated as married for federal tax purposes (IRS, 2013). That ruling applies regardless of whether the couple resides in a jurisdiction that recognizes same-sex marriage or in one that does not. The IRS began implementing this tax treatment following the Supreme Court's decision invalidating a key provision of DOMA. The IRS maintains that same-sex couples will be recognized as married for all federal income tax purposes, including estate and gift taxes.
The objective of this paper is to investigate how the federal and state governments handle the tax treatment of same-sex married couples following the Supreme Court decision declaring DOMA unconstitutional.
