2026 Idaho paycheck guide

What this statewide profile models

State wage-tax treatment

The profile applies 2 configured statewide rate bands after modeled adjustments. It does not infer local taxes or unsupported credits.

Employee payroll items

No employee payroll assessment is configured in this statewide profile. That is a model statement, not a claim that every employer or locality has no additional deduction.

401(k) treatment

Configured pretax 401(k) contributions reduce Idaho taxable wages in this model, subject to the calculator limit and profile boundaries.

Planning focus

Compare Idaho with the curated Washington and Oregon scenario while keeping all salary and contribution inputs identical.

Profile boundaries

These limits stay visible so a statewide estimate is not mistaken for a filed return or an address-specific withholding calculation.

  • Idaho state income tax is modeled as an annual-liability estimate, not employer withholding.
  • The zero-rate bracket amounts are Idaho's tax-year-2025 figures; Idaho Code §63-3024 indexes them annually and the 2026 amounts were not yet published, so estimates are overstated by roughly $5 to $8.
