Moving from MiWAM to MiUI

As part of the transition to MiUI, UIA will attempt to convert all Employer-TPA relationships that currently exist in MiWAM into MiUI, including WOTC TPAs. The exception is if the employer has two or more assigned TPAs in MiWAM. In this case, the employer will not be added to the TPA’s record, and must grant permission to that TPA after the launch of MiUI in early 2026. They will need the TPA’s new MiUI TPA ID to complete this action. TPAs with the proper authorization will also be able to associate themselves with an employer on their own outside of the Automatic Assignment process.

Though Employer-TPA relationships are being brought over from MiWAM, the specific roles that TPAs were previously assigned are not. Details on which TPAs will receive which roles can be found in the TPA Assignment & Association Quick Reference Guide on MiUI University.

For a few months after the Tax Phase of MiUI goes live, employers and TPAs will be performing unemployment insurance duties in two systems. Tax functions will be completed in MiUI, while benefits functions will still be completed in MiWAM. It is essential all employers and TPAs have a MiWAM account. Both systems will be used to deliver alerts and updates throughout this interim period, providing clear communication about roles and responsibilities.

Yes, TPAs will require access to both MiWAM and MiUI during the Two System Transition period. TPAs will use their existing MiWAM user ID and password to access MiWAM. TPAs will create a MiLogin account for each user to access MiUI. There is no user ID or password synch between MiWAM and MiUI during this period:
