See your real take-home pay in Idaho after federal tax, ID state tax, FICA, 401(k), and health insurance.
Idaho keeps things simple with a flat 5.695% income tax — every dollar of taxable wages is taxed at the same rate, no brackets to climb. Combined with federal income tax and 7.65% FICA, that flat rate determines how much of your salary actually reaches your bank account. The calculator below breaks down a Idaho paycheck line by line, including 401(k) and health insurance deductions.
Flat 5.7% state income tax, after a $15,000 state deduction (single). Married brackets are approximated as doubled single-filer thresholds. Uses the latest available state rates where 2026 figures aren't final.
