Idaho state tax: Overview

Idaho moved to a flat income tax rate this year. Social Security benefits aren't subject to Idaho state tax, but the state may tax other types of retirement income. Idaho has one of the lowest sales tax rates in the U.S. However, it is one of the few states that taxes groceries.

Alcohol and tobacco taxes are lower in Idaho than in many other states. Property taxes in the Gem State are also lower than those in much of the country.


[Data for this state tax guide was gathered from several sources including the U.S. Census Bureau, the state’s government website, the Sales Tax Handbook, and the Tax Foundation. Property taxes are cited as a rate percentage rather than the assessed value.]
