UIA Launches New Employer Portal: MiUI Goes Live December 15

The Michigan Unemployment Insurance Agency (UIA) is transitioning its services for employers from the current Michigan Web Account Manager (MiWAM) system to a new platform called MiUI, launching on December 15, 2025. 

This transition is part of a modernization effort to create a more efficient and secure system for employers, third-party administrators (TPAs), and claimants. In preparation for the transition, some MIWAM capabilities used by employers and TPAs will be reduced and/or discontinued. The process begins in November, starting with e-Registration being temporarily unavailable.

Key details of the transition

• Phased rollout: Certain MiWAM functions, such as eRegistration and business transfers, are being phased out between November 7 and December 5, 2025, in preparation for the launch.
• Launch date: MiUI officially launches on December 15, 2025. Employers and TPAs will use MiUI to file quarterly wage and tax reports, upload wage files, and more.
• Transition period: After December 15, employers and TPAs will temporarily need to use both the MiUI system for tax functions and the MiWAM system for benefits functions until the summer of 2026, when all functions will be in MiUI.
• Access: MiUI will be accessed through a MiLogin for Business account, a single sign-on solution used by the State of Michigan.

What should employers do to prepare?

If you already have a MiLogin account, you do not need to create a new one for MiUI. To log in or create your account, visit the MiLogin for Business website. Additional information about MiLogin for Business and adding MiUI to your account can be found in the Step-by-Step Guide posted on MiUI University.

Employers and TPAs are advised to ensure their MiWAM accounts are active, review contact information, and confirm authorized user permissions before the transition is complete.
