Minnesota residents who live part time elsewhere could see a dramatic jump in their tax bills as a result of a ruling Wednesday by the state Supreme Court.
The 4-3 opinion sharply defined what the justices described as an ambiguous law that determines when a person is considered to be a resident in Minnesota. The law says full-time residency starts at 183 days, or half the year.
In the case of Curtis and Stacy Marks, who moved to Minnesota from Florida in August 2007, the court determined that the couple surpassed the half-year limit. The Markses spent 104 days in Minnesota before settling permanently in the state, time that the majority ruled should be tacked onto the months the couple spent in the state after their move. That made them responsible for a full year's taxes, and will cost them at least an additional $390,000.
The Minnesota Department of Revenue declined to comment on how it will use Wednesday's ruling in future residency tax cases. But Barry Gersick, the Markses' attorney, predicted the case will have broad implications for snowbirds and others.
"I feel bad for my clients," said Gersick, a partner at Maslon Edelman Borman & Brand. "I'm not sure how the Department of Revenue will use this ruling moving forward, but it will definitely have an impact beyond our narrow case."
The ruling reverses a 2014 state tax court decision by Judge Joanne Turner, who sided with the Markses. She had ruled that only days spent in Minnesota as nonresidents should be counted toward the 183 days for tax purposes.
The revenue department argued that a person can claim residency elsewhere, but the clock starts ticking if 183 days or more are spent in Minnesota in a given year and that person keeps an abode in the state. An abode means a residence with a kitchen and a bathroom.
The Markses moved from Minnesota to Florida in 1999. They decided to return to Minnesota after their children were accepted into a private school. The revenue department audited the couple in 2009, reviewing past tax returns.
