WHEREAS, the Internal Revenue Service has announced that, under Revenue Ruling 2013-17, same-sex couples legally married in a state that authorizes such marriages, regardless of their place of domicile, may file a joint federal individual income tax return; and
WHEREAS, the tax code of Missouri is coupled to the federal tax code, and Missouri tax filers are required to utilize information from their federal tax return when completing their Missouri state income tax return; and
WHEREAS, section 143.031.1, RSMo, mandates that "[a] husband and wife who file a joint federal income tax return shall file a combined [state] return"; and
