Idaho Paycheck Calculator 2026
Idaho charges a flat 5.3% income tax — the rate was cut in 2025 — and it only applies above the standard deduction, which matches the federal amount ($16,100 single / $32,200 married in 2026). That deduction shields a meaningful share of a typical paycheck from state tax.
The calculator below applies 2026 federal brackets, FICA and Idaho's 5.3% flat rate after the standard deduction. Idaho has no local income taxes on wages.
The result is an annual 2026 tax-liability estimate apportioned across the pay frequency you choose. It does not reproduce employer withholding from your Form W-4.

Idaho income tax in 2026, briefly
Idaho uses a flat 5.3% statutory rate in this interim model. Deductions mean the effective rate on gross wages can differ.
Figures use 2026 rates and are estimates for planning — not tax advice.
Idaho take-home pay by salary (2026)
Planning estimates across common annual salaries in Idaho. Figures assume a single filer with no 401(k) or other entered deductions. Contributing pre-tax can reduce income tax but also reduces current take-home cash, so it does not automatically increase net pay.

- Is this the amount an employer will withhold in Idaho?
- No. This tool estimates annual federal and state income-tax liability and employee payroll taxes, then divides the annual result by the number of periods you select. Employer withholding uses pay-period wages, Form W-4 details, state forms and payroll rounding.
- How is this estimate calculated?
- We estimate annual federal income-tax liability from 2026 brackets and the standard deduction, employee Social Security and Medicare taxes including Additional Medicare Tax where applicable, the available state schedule, any local rate you enter, and the cash effect of entered deductions. Credits and a full Form W-4 are excluded.
- How reliable is this Idaho paycheck estimate?
- It is a planning scenario, not a payroll prediction. It does not model credits, every benefit rule, work/residence-state interactions, year-to-date withholding or all state payroll programs. Your pay stub and filed return are the relevant records.
