Idaho Paycheck Calculator
Idaho simplified its income tax to a flat rate structure in 2022, reducing and flattening its prior graduated system. In 2026, Idaho's flat income tax rate is 5.695% on all taxable income. This flat rate was reduced from 5.8% in 2024 under HB 292. Idaho lawmakers continue to evaluate further rate reductions to remain competitive with neighboring Washington (no income tax) and Wyoming (no income tax).
Idaho does not levy city income taxes in Boise, Meridian, Nampa, or any other municipality. The state flat rate is the only sub-federal income tax on Idaho wages. Idaho has no SDI program.
Idaho's standard deduction conforms to federal amounts, and pre-tax 401(k) contributions reduce Idaho taxable income through federal AGI conformity. Idaho has experienced significant population growth from Californians and Pacific Northwest residents — the tax-friendly environment relative to California (13.3%) and Oregon (9.9%) is a major driver of this migration.
