Open Relocation Tax Calculator →Relocating to Idaho means adjusting to its flat 5.3% state income tax . Whether this helps or hurts depends on where you are coming from. Moving from a high-tax state like California or New York could still save you money, while relocating from a no-tax state will reduce your take-home. Idaho's cost of living index of 95 is another crucial factor: a lower salary in a cheaper area can still leave you better off. This calculator compares your current and post-move take-home with Idaho's rates.
