How Idaho take-home pay is calculated
Idaho taxes wage income at a single flat rate of 5.3% in 2025, after a 0% bracket on the first $4,811 of taxable income for single filers ($9,622 for joint filers). The rate dropped from 5.695% to 5.3% under HB 40, signed in March 2025 and retroactive to January 1, giving Idaho residents a slightly larger take-home paycheck than the prior year. There are no local or city income taxes in Idaho, so this flat state rate is the only state-level income tax burden on wages.
