Check how much of a Idaho traditional IRA contribution may be deductible.
2026-era federal traditional IRA limits ($7,000 under 50; $8,000 50+). If covered by a workplace plan, the deduction phases out above income thresholds. The optional Idaho state-tax saving uses an approximate state rate.
Deduction
Deductible = limit adjusted by plan coverage and income phase-out

Idaho treats IRA contributions like the federal rules. If (and only if) your contribution is federally deductible, it is generally deductible on state income tax too.
A non-deductible traditional IRA can still grow tax-deferred, or look at a Roth IRA / backdoor Roth.
