Q4 2025 Wage Reports & Premium Payments Due Feb. 2

Quarter 4 2025 wage reports and premium payments are due Monday, February 2, 2026. Here are some reminders for TPAs reporting employer wages:

  • Employer Reporting Units have been discontinued. *All wage records must be reported from the employer’s primary EAN. When reporting employer wages via file upload, unit number values must be entered as “000”. (*For reimbursable employers, wage records must be reported from the former reporting unit’s newly-created EAN.)
  • Review wage file error reports, and resubmit rejected records. Error reports are available in the “TPA Wage File History” screen to view EANs associated with rejected wage records. Missing or inaccurate wage information can result in penalties and interest charges to employer accounts.
  • Report wages for multi-state workers correctly. Out-of-state wage credit requests must be submitted manually in MyUI Employer+. See how to manage out-of-state wage credits for more information and instructions. 

Voluntary Premium Payments

Employers with an experience rate, also called a computed rate, may be eligible to submit a Voluntary Premium Payment (VPP). VPPs are not a prepayment for premiums an employer will owe but can change an employer’s percent of excess, which may lower their UI rate in a calendar year. Visit the Premium Payments page for more information.

Voluntary Premium Payments must be submitted online by Monday, March 16, 2026. Paper checks for VPPs are no longer accepted.

Employer Charging Correspondence Schedule Change

The Division will change the timing of quarterly employer charging correspondence delivered by mail beginning in April 2026. 

Impacted Correspondences: 

  • The Quarterly Statement of Benefit Charges (for contributory and reimbursable employers)
  • The Quarterly Reimbursable Bill (for reimbursable employers only)

Beginning April 2026 and going forward, quarterly Statements of Benefit Charges and Reimbursable Bills will be available online and mailed on:

  • April 5 (for Quarter 1)
  • July 5 (for Quarter 2)
  • October 5 (for Quarter 3)
  • January 5 (for Quarter 4)

Payments are due 30 days from the mail date listed on the Reimbursable Bill. This change is meant to provide more timely benefit charging information to employers (and agents), and to align payment deadlines with the quarterly reporting and premium payment deadlines.

Electronic Claims Correspondence

Payroll and HR service providers, and other TPAs no longer receive fact-finding requests for employer clients by mail. All UI claims correspondence, including fact-finding questionnaires and other separation information requests, must be sent and responded to by Division-approved electronic means only, in accordance with State regulations. 

All TPAs are required to receive and respond to fact-finding requests online in MyUI Employer+, or through SIDES exchanges. Please ensure you have access to employer client accounts in MyUI Employer+ (or SIDES), and are assigned the appropriate roles to view and respond to benefits correspondence electronically.

See the Electronic Communications Requirements page for more information.

MyUI Employer+ Resources for TPAs

UI Employer Client Onboarding

Bringing on new employer clients? 
Here’s what TPAs and employers need to know to get started in MyUI Employer+.

 

All employers must create an employer account inside the MyUI Employer+ premium and wage reporting system. TPAs cannot register an employer account on behalf of a client.

 

TPAs will need to create a MyUI Employer+ TPA account and request access to employer accounts in order to conduct UI business on behalf of their clients. Employers will review and approve TPA association requests inside MyUI Employer+.

 

Employers and TPAs are responsible to maintain current contact information and communication preferences including addresses, emails, and other information inside MyUI Employer+.

 

Employers with good reason to conduct business with the UI Division by U.S. Mail must apply for a non-electronic communications waiver. Approved waivers are valid for one calendar year and must be renewed annually.

 

Premium payments and wage reports are due on the last day of the month following the end of a quarter (April 30, July 31, October 31, and January 31). Employer accounts with missing or overdue wage reports and premium payments are subject to penalties and interest.

 

Employers and TPAs should ensure they are submitting accurate and timely wage and fact-finding information. Employer wage detail reports and fact-finding documents submitted with errors, inaccuracies, or missing information may be subject to penalties and interest charges.
