On February 16, 2016, the Michigan Department of Treasury announced its new acquiescence policy with respect to certain court decisions affecting state tax policy. The Treasury’s acquiescence policy is similar to the Internal Revenue Service’s (IRS) policy of announcing whether it will follow the holdings in certain adverse, non-precedential cases.
In Michigan, while published decisions of the Michigan Court of Appeals and all decisions of the Michigan Supreme Court are binding on both the Treasury and taxpayers, unpublished decisions of the Court of Appeals and decisions of the Court of Claims and the Michigan Tax Tribunal are binding only on the parties to the case and only with respect to the years and issues in litigation. Nonetheless, the Treasury has determined that a particular decision, while not binding, may constitute “persuasive authority in similar cases.” The Treasury may therefore decide to follow a non-precedential decision that is adverse to the Treasury in other cases, a policy known as acquiescence. Beginning with its May 2016 quarterly newsletter, the Treasury will publish a list of final (i.e., unappealed), non-binding, adverse decisions, and announce its acquiescence or non-acquiescence with respect to each. The Treasury points out that an indication of acquiescence does not necessarily mean that the Treasury approves of the reasoning used by the court in its decision. (more…)
