How Idaho taxes your paycheck in 2026

Idaho moved to a flat tax and, via House Bill 40 (March 2025), cut the rate to 5.3% retroactive to 2025. The Idaho State Tax Commission uses the federal standard deduction as its starting point and exempts the first roughly $4,811 of single ($9,622 married) taxable income, so lower earners pay an effective rate below 5.3%.

The 5.3% flat rate after an exempt band

Idaho conforms to the federal standard deduction ($16,100 single / $32,200 married for 2026), then exempts an additional first band before the 5.3% rate applies. A single filer earning $65,000 pays 5.3% on income above roughly $20,900 of combined deduction-and-exempt amount.
