Apply for a withholding account
You must have a federal Employer Identification Number (EIN) before you apply for an Idaho withholding account. Apply for an EIN with the IRS.
After you have your EIN, visit our Idaho Business Registration Information guide. Follow the instructions to register for an Idaho withholding account.
Use the same employer name and EIN you'll use to prepare your employees' W-2s.
An Idaho withholding account number isn't transferable.
If you're a new owner of an existing business, don't use a return or payment voucher that Idaho issued to the former owner of the business. You must apply for a new withholding account.
You must apply for a new withholding account if you acquire a business, get a new federal EIN, or change your business entity (e.g., a sole proprietorship becomes a corporation).
