Calculate your net paycheck in Idaho after federal taxes, the 5.3% top state income tax rate, and FICA deductions. Formula shown, sources cited β no account required.
The state levies a flat income tax of 5.3% on all taxable income β a relatively simple structure that makes it easy to estimate take-home pay. For a household at the median income of $81,166, the state tax alone represents roughly $4,302 before deductions. Combined with federal taxes, a median earner typically keeps somewhere in the range of 70β75 cents of every dollar earned, depending on filing status and deductions. Cost of living here runs almost exactly at the national average β a cost-of-living index of 99.3 β which means purchasing power is close to what the dollar buys in a typical US city. That balance makes salaries more livable than in coastal markets where pay is higher but costs are dramatically steeper. The state does not impose a local income tax on top of the state rate in most jurisdictions. Workers in tech, healthcare, agriculture, and construction make up a large share of the workforce.
