Overview
Idaho, also known as the Gem State, has seen explosive growth and is becoming a popular place to live. The state’s low unemployment rate and affordable housing market are definitely a draw, but it’s also very tax-friendly to retirees. Idaho has one of the lowest income tax rates in the country. Its sales tax and property tax rates are also fairly modest. When combined, Idaho has the lowest per capita tax burden in the nation.

Idaho Sales Tax
Idaho has a state sales tax rate of 6%. Local governments (cities and auditorium districts) are also allowed to levy an additional sales tax of up to 3%. These are sometimes referred to as local “option” taxes because the taxes are decided by the voters in the community affected. Although auditorium districts are limited to charging sales tax for lodging only, city governments may levy a sales tax on anything subject to sales tax at the state level.
The average sales tax rate for the state is 6.1%. Sun Valley has the highest sales tax rate at 9%. Most cities in Idaho, however, do not charge above the state’s rate of 6%.
