Bert Baker and Ernestine Moffet were never formally married but have lived together as husband and wife for the last 14 years. Bert and Ernestine reside in Washington, D.C., a jurisdiction that recognizes common law marriages as valid. Consequently, they filed both a joint district income tax return and a joint federal income tax return for the last eight years. Bert and Ernestine are planning to move their household to Frederick, Maryland, and become permanent residents of that state. Maryland doesnt recognize common law marriages. Will Bert and Ernestines change in residence allow them to avoid the marriage penalty by filing as single individuals?
