How Idaho taxes your income in 2026

Idaho's flat 5.3% applies to your federal taxable income — the number on your federal return after the standard deduction. Because Idaho starts from federal taxable income, there is no separate Idaho standard deduction to subtract again. The rate has fallen every year recently: 6% in 2022, 5.8% in 2023, 5.695% in 2024, and 5.3% from 2025 (HB 40), reflecting Idaho's run of budget surpluses.

Simple, low-friction tax system

Idaho has no local or city income taxes, no estate tax, and no tax on Social Security benefits. Retirement income beyond Social Security is mostly taxable at the 5.3% rate, though certain public-safety and government pensions qualify for partial deductions. Idaho's 6% state sales tax is the main other broad-based levy; property taxes are comparatively low by national standards.

What this calculator includes (and excludes)

This estimate covers federal income tax, FICA, and Idaho's 5.3% flat tax computed on federal taxable income — the same starting point Idaho's own return uses. It does not model pension subtractions, itemized deductions, the grocery tax credit, or other credits. Figures are estimates for planning purposes, not tax advice.
