In 2003, the Massachusetts Supreme Court ruled that state laws excluding same-sex couples from marriage violate the state constitution, allowing same-sex couples to marry in Massachusetts (Goodridge v. Dep't of Pub. Health, 440 Mass. 309 (Mass. 2003)). Same-sex couples residing in Massachusetts have been able to marry since May 17, 2004, and those who reside outside the state have been able to marry in Massachusetts since July 31, 2008.
The U.S. Supreme Court subsequently issued a decision legalizing same-sex marriages in all states and requiring all states to recognize same-sex marriages legally performed in other jurisdictions (Obergefell v. Hodges, 135 S.Ct. 2584 (2015)).
Effect on employers. Employers in Massachusetts are required to provide the same benefits, such as health insurance, to employees in same-sex marriages as provided to employees in opposite-sex marriages. Employees with same-sex spouses are entitled to family leave benefits and deductions provided for under state tax laws.
