Idaho moved to a flat income tax in 2023, replacing a graduated schedule. The current rate is 5.3%, applied to taxable income above an exempt threshold of $4,811 — so the first tranche escapes tax entirely. Idaho also matches the federal standard deduction, which shelters a substantial further amount. There are no local income taxes anywhere in the state.
From graduated to flat, with a zero band retained
Idaho's income tax had four brackets topping out at 6.5% as recently as 2021. A sequence of reforms compressed them, and 2023 legislation replaced the structure with a single rate — initially 5.8%, since reduced to 5.3%.
Unusually for a flat-tax state, Idaho retained a zero-rate band: income below $4,811 of taxable income attracts no tax at all. Combined with a standard deduction matching the federal figure, this means an Idaho single filer pays nothing on roughly the first $21,000 of gross income.
That design softens the regressive edge that flat taxes usually carry. Idaho's effective rate rises meaningfully with income even though its statutory rate does not, which is a more progressive outcome than the headline structure suggests.
A fast-growing state with a low burden
Idaho has been among the fastest-growing states in the country for a decade, driven heavily by inbound migration from California and Washington. The tax comparison is part of the reason: Idaho's flat 5.3% sits well below California's mid-range brackets, and Idaho has no local income tax where many California costs are locally variable.
The offset is property tax, which has risen sharply alongside house prices in the Boise area. Idaho offers a homeowner's exemption reducing the taxable value of an owner-occupied home, and a circuit-breaker programme for older and lower-income homeowners, but the underlying valuations have moved faster than the relief.
Sales tax is 6% at state level with limited local additions, and Idaho taxes groceries — offset by a per-person grocery credit claimed on the income tax return, which the state has increased in recent years.
Retirement income and what comes off a payslip
Idaho does not tax Social Security benefits. It offers a deduction for certain retirement income — principally civil service, military, firefighter and police pensions — for taxpayers aged 65 and over, or 62 if disabled. Ordinary 401(k) and IRA distributions do not qualify and are taxable at the flat rate.
No Idaho city or county levies an income tax, and the state runs no disability or paid leave programme, so an Idaho payslip carries federal deductions plus the state income tax and nothing else.
Pre-tax 401(k) contributions reduce Idaho taxable income as well as federal, since the state builds on federal taxable income concepts.
Frequently Asked Questions

Do Boise or Idaho Falls charge local income tax?+
No. No Idaho city or county levies an income tax, so withholding is the same throughout the state.
