You may file your withholding returns online at tap.utah.gov. You must include your FEIN and withholding account ID number on each return.You may be exempt from Utah withholding requirements if you do business in Utah for 60 days or less in a calendar year and have Tax Commission approval. You will need forms for the various permits that are required. Keep in mind, filling out these worksheets and forms is NOT equivalent to applying for a permit.
