Trump Accounts in Wisconsin: State Tax Treatment
By Forrest Baumhover, CFP®, EA · Last verified September 2, 2026
Whether Wisconsin taxes a Trump Account's growth and distributions the way the IRS does — checked against Wisconsin's own conformity law, not a national summary.
Does Wisconsin follow the federal rule?
Wisconsin 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 December 31, 2022. That date is before OBBBA's July 4, 2025 enactment, so Wisconsin's general conformity does not by itself pick up §530A.
What this means for a Trump Account in Wisconsin
Based on that mechanism alone, Wisconsin does not currently follow the federal §530A treatment — absent separate state action, growth inside a Trump Account could be taxed by Wisconsin in the year it's realized rather than deferred the way federal law defers it.
A note on this determination
Wisconsin's conformity date is fixed well before OBBBA's enactment, and no Wisconsin-specific 2025/2026 legislative action adopting OBBBA or Trump Account treatment was found (unlike California, Arizona, or Virginia). Confirmed directly against the Wisconsin State Legislature's own official statute site.
