To register as an employer, you need to obtain a federal Employer Identification Number (EIN) from the IRS and secure workers compensation insurance. You then need to establish state income tax withholding and unemployment insurance tax accounts by filing IBRS.
Have employees complete and keep in employer’s files: Employee’s Withholding Certificate W-4 obtained from the IRS and Employment Eligibility Verification Form I-9 obtained from the U.S. Department of Immigration and Naturalization. New employees need to be reported to the Idaho Department of Labor within 20 days of hire. See New Hire Reporting.
