It depends. According to the Utah State Tax Commission, the state ID should be 14 characters, the first 11 are a numbers, and the last three are "WTH". Have you entered an ID that looks like this: 12345678901WTH? If the numbers you have are a string of less than 11 digits, some customers have had success adding zeros to the ID you have. Otherwise, you should contact your payroll department for the correct state ID.
