Idaho's income tax, in context
Idaho collapsed to a flat 5.3% in 2023 after years of a graduated schedule, applying the rate only above a small exemption amount. The state starts from federal taxable income, so the federal standard deduction carries through, and Idaho has been using surplus revenue to trim the rate in successive years.
