Trump Accounts in Michigan: State Tax Treatment
By Forrest Baumhover, CFP®, EA · Last verified September 2, 2026
Whether Michigan taxes a Trump Account's growth and distributions the way the IRS does — checked against Michigan's own conformity law, not a national summary.
Does Michigan follow the federal rule?
Michigan uses "fixed-date" (static) conformity: its tax code names a specific historical IRC date rather than following current federal law automatically. Its conformity date is January 1, 2025. That date is before OBBBA's July 4, 2025 enactment, so Michigan's general conformity does not by itself pick up §530A.
What this means for a Trump Account in Michigan
Michigan's conformity to §530A is partial — some elements of the federal treatment apply for state purposes and some do not.
A note on this determination
Michigan's default fixed date (January 1, 2025, set by 2025 PA 24) just misses OBBBA's July 4, 2025 enactment — but the statute itself gives every taxpayer an election to use the Internal Revenue Code "in effect for the tax year" instead, which is current law including §530A. Treasury's own February 2026 decoupling notice mandates decoupling only for bonus depreciation and R&E-expensing provisions, nothing that would block a taxpayer from electing into §530A treatment. The real-world answer therefore depends on which option a Michigan return actually uses, not a single fixed answer.
