Trump Accounts in Idaho: State Tax Treatment
By Forrest Baumhover, CFP®, EA · Last verified September 2, 2026
Whether Idaho taxes a Trump Account's growth and distributions the way the IRS does — checked against Idaho's own conformity law, not a national summary.
Does Idaho follow the federal rule?
Idaho 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, 2026. That date is on or after OBBBA's July 4, 2025 enactment, so Idaho's general conformity picks up §530A as part of the Code it already follows.
What this means for a Trump Account in Idaho
Based on that mechanism, Idaho currently follows the federal §530A treatment: contributions and growth are not separately taxed by the state before distribution, the same deferral the federal rule provides.
A note on this determination
Idaho decouples from IRC §168(k)/(n) bonus depreciation and certain R&E expensing, but no §530A-specific decoupling was found; §530A is captured by the general January 1, 2026 conformity date.
