Retiring in Idaho
Idaho trades fast rising home prices for mountains, rivers, and no state tax on Social Security.
A fit if
Four seasons, mountains and rivers close by, and a break on Social Security at the state level fit the kind of retirement in mind.
Hard look if
Home prices in and around Boise have climbed quickly, and winters plus wildfire smoke season are part of the yearly rhythm.

How the plan models Idaho
The state lines the calculator actually changes.
These are the assumptions the planner applies for Idaho. They are blended, middle-bracket planning figures, not a tax return. Exemptions, county rules, and your own income mix can move the real number.
