Idaho Paycheck Calculator

Living on a paycheck in Idaho

Idaho uses a flat income tax of about 5.8% on taxable income, so a paycheck in Boise, Idaho Falls, or Coeur d'Alene loses the same state percentage regardless of size. The flat structure keeps Idaho take-home pay simple to forecast.

With a generous state standard deduction tied to the federal one, lower-income workers shield a meaningful chunk of pay from state tax. The calculator above reflects that in your estimate.

How Idaho taxes are withheld

An Idaho paycheck has federal income tax, Social Security (6.2%), and Medicare (1.45%) withheld, plus Idaho's flat 5.8% income tax on taxable income after the state standard deduction. Pre-tax contributions lower both federal and Idaho taxable wages.

What shapes your take-home in Idaho

Idaho's flat rate means your federal filing status and pre-tax benefits matter most for net pay. As a rough illustration, a single filer earning $75,000 might owe somewhere around $3,400 in Idaho income tax for the year after the standard deduction. Your exact take-home is shown above.

Getting the most from each paycheck in Idaho

Because pre-tax 401(k) and HSA contributions cut both your federal and 5.8% Idaho tax, they are the most efficient way to keep more of your paycheck. Revisit your W-4 after income changes so your withholding stays close to your actual liability.
