Idaho Withholding Tax Setup

If you plan to hire employees in Idaho, you are required to register with the Idaho State Tax Commission for a withholding tax account. Note: When registering a new business you can also register for Unemployment Insurance at the same time.

  1. Create an Idaho Business Registration System Account

    Before submitting or updating an Idaho Business Registration, create an Idaho Business Registration System account if you haven't already done so. This is used to save progress in an existing application and add additional accounts later.

  2. Submit the Idaho Business Registration Form

    Register as a new business and request a Withholding Account Number online by selecting "New Applicant" under "Purpose of Registration." Once you complete the form, you will see the list of permits and accounts needed, which will be requested when you submit the form.

  3. Create an Idaho TAP Account

    Create an Idaho Taxpayer Access Point account if you haven't already done so. Payments for most taxes in Idaho can be made electronically using Idaho Taxpayer Access Point.

  4. Configure Payroll with Your Withholding Account Number

    Your payroll provider needs your withholding account number and deposit schedule to remit taxes properly.

Idaho Unemployment Insurance Setup

If you have total wages of $1,500 or more in a calendar quarter in the current or preceding year you must register with the Idaho Department of Labor and pay Unemployment Insurance Tax. Note: When registering a new business you can also register for income tax withholding at the same time.
