Idaho Paycheck Calculator 2026

Works offline — your inputs never leave this device. How that works
Estimate only: this is an approximation, not a copy of Idaho's withholding tables — though it is close, because Idaho's own percentage computation method is a single rate applied to wages above a threshold. It annualizes your pay, subtracts the Idaho threshold for your filing status and applies the 5.3% rate. Your employer works from your Form ID W-4, so your actual withholding may differ. Use the Idaho State Tax Commission's own withholding tables for an official figure.

What is the Idaho income tax rate for 2026?
Idaho taxes wage income at a flat 5.3%, after the deductions and exemptions its withholding guidance applies. The figure was transcribed from Idaho State Tax Commission — EPB00744, Table for Percentage Computation Method of Withholding (07-23-2026), Annual Payroll Period and verified on 2026-07-31. Because withholding tables and annual calculations differ slightly, treat the result as an estimate and check it against the state's own table.
Why does this differ from my actual pay stub?
Two reasons. Pre-tax items — retirement contributions, health premiums, HSA deductions — reduce taxable pay and are not modelled here. And this uses an annualized approximation of the state's schedule rather than the exact withholding tables your employer's payroll system uses, which is disclosed on every result.
