Idaho Paycheck Calculator

Let’s calculate the taxes for someone earning $55,000 a year living in Idaho, USA.

In Idaho, the state income tax rates range from 1.125% to 6.925%, depending on income level. Let’s assume a flat rate of 6.925% for simplicity.

Given an annual salary of $55,000:

  • Calculate state income tax:

State income tax = $55,000 * 0.06925 = $3,813.75

  • Calculate net pay:

Net pay = $55,000 – $3,813.75 = $51,186.25 per year

  • Calculate monthly net pay:

Monthly net pay = $51,186.25 / 12 = $4,265.52

So, if you earn $55,000 a year in Idaho, your net pay per month would be approximately $4,265.52.

For Idaho, the marginal tax rate is the same as the flat rate, which is 6.925%. This means any additional income you earn will be taxed at this rate. For example, if your salary increases by $100, you’ll pay an additional $6.925 in taxes, leaving you with an extra $93.075 in net pay.
