UIWebTax is an online application for filing quarterly wage reports. It's a good option for employers filing a no-payroll report or for those filing for fewer than 2,000 employees. We recommend  EAMS for most employers.

How to use UIWebTax

Before you begin

  • Have your ES reference number
  • Have your Federal Employer ID Number (EIN)
  • Have your UBI Number
  • Have a valid e-mail address (to receive confirmation)

Filing your report

  • Go to UIWebTax
  • Complete your report (2,000 employee limit)
  • Review your report before submitting
  • Click 'File now' from the 'File Report' screen to submit
  • You should see a confirmation number screen. If you don't, try again.
  • Write down the confirmation number that generates after the report is successfully filed

Important: There is a 2,000 employee limit, no option to save reports or data from quarter to quarter, no payment option in the application. And UIWebTax is not compatible with Google Chrome.
