"This report will provide an overview of the potential federal tax implications for same-sex married couples of the U.S. Supreme Court ruling in 'United States v. Windsor', with a focus on the federal income tax. Estate tax issues are also discussed. Importantly, this report focuses on changes in the 'interpretation and administration' of federal tax law resulting from the Court's decision. The decision itself did not amend federal tax law. This report is not intended to address 'all' tax-related issues that may arise as a result of the 'Windsor' decision. Such discussion is beyond the scope of this report."
