Wendell vs. Commissioner of Revenue
Annotate this Case
The case involves a dispute over two years of Minnesota individual tax returns filed by Christopher and Nancy Wendell, residents of Wisconsin. In 2019 and 2020, the Wendells filed joint tax returns reporting no Minnesota taxable income, despite receiving over $1 million in payments from Minnesota sources. The Wendells claimed that the payments were not taxable wages or ordinary business income. The Commissioner of Revenue disagreed, modified the Wendells’ reported income, assessed additional income tax, and imposed a 25 percent penalty for filing a frivolous tax return. The Wendells appealed the Commissioner’s assessment, and the Minnesota Tax Court granted summary judgment in the Commissioner’s favor.
The Minnesota Tax Court found that the Wendells’ tax liability was correctly calculated and adjusted, that no material facts were in dispute, and that the frivolous return penalty statute was constitutional. The Wendells then appealed to the Minnesota Supreme Court.
The Minnesota Supreme Court affirmed the decision of the tax court. The court held that the Commissioner of Revenue had the authority to adjust the Wendells’ reported federal adjusted gross income, the tax court did not err in granting summary judgment in favor of the Commissioner, and the statutory penalty for filing a frivolous return is constitutional. The court rejected the Wendells' arguments that the penalty for filing a frivolous tax return was unconstitutional under the Due Process Clauses and Excessive Fines Clauses of the United States Constitution and Minnesota Constitution or the Equal Protection Clause of the United States Constitution.
