How this is calculated
Idaho uses a flat individual income tax rate with a state standard deduction in our maintained library. This page applies that estimate with 2026 federal withholding and FICA.
Use this page for statewide Idaho planning, not for reconciling an employer's exact Idaho withholding tables.
Pair with Washington or Wyoming pages when comparing regional no-state-tax alternatives.
