How Idaho taxes your paycheck in 2026

Idaho taxes wages at a flat 5.3% for 2026. Withholding starts once annual wages pass $16,100 (single or head of household) or $32,200 (married). Traditional 401(k) contributions and pre-tax health premiums are not taxed. There are no employee-paid state payroll taxes and no local income taxes.

Income tax rate: 5.3% of taxable wages.

Standard deduction: $16,100 single or married filing separately; $32,200 married filing jointly; $16,100 head of household.
A traditional 401(k) lowers your Idaho taxable wages; pre-tax health premiums do.

City and county taxes

Idaho cities and counties do not tax wages.

What this calculator simplifies

Uses the Idaho withholding tables revised July 23, 2026. Before that revision, Idaho's 2026 tables subtracted a child tax credit allowance per Form ID W-4 allowance; the Tax Commission then announced the credit had sunset, set the allowance to $0, and told employers to use the new tables going forward without adjusting earlier paychecks. Paychecks earlier in 2026 may have had less withheld.
Head of household uses the single table, as Idaho's withholding tables do. Idaho's actual 2026 return uses the federal standard deduction, which is larger for heads of household.
Dependents do not change Idaho withholding in 2026.
This is withholding, not your final Idaho tax. Credits such as the grocery credit are not reflected.
