Cost of Living in Idaho 2026: City-by-City Breakdown

Idaho is no longer the universal bargain it was in 2018, but it remains a solid value once you look beyond Boise. The statewide cost of living index sits right at the national average, the new 5.8% flat income tax is moderate, and property taxes are among the lowest in the country. This guide breaks down what Idaho really costs by city in 2026.

Quick Summary

Boise has appreciated dramatically and now runs above the national average. The rest of Idaho — Idaho Falls, Pocatello, Twin Falls, Coeur d'Alene — remains genuinely affordable. Idaho's 5.8% flat income tax, 6% sales tax and 0.49% effective property tax rate keep total tax burden moderate. Lifestyle highlights include outdoor recreation, mountain access and a low-density quality of life.

Housing Market Reality

Boise's housing surge of 2020–2022 was one of the most dramatic in the country, with prices effectively doubling in a few years. The market has since stabilized, with year- over-year appreciation cooling to roughly 2–4%. Median home prices in central Boise hover around $510,000, while suburbs like Nampa and Caldwell remain meaningfully cheaper at $385,000 and $345,000 respectively. Outside the Boise metro, the housing market is much more affordable — Idaho Falls, Pocatello, and Twin Falls all sit well below the national median.
