MiUI Resources for Employers and TPAs
This page provides regularly updated helpful information, links, and resources about what employers and third-party administrators (TPAs) need to know about MiUI.
MiUI for tax is now live! Employers and TPAs will use MiUI for tax functions such as filing quarterly wage and tax reports, uploading wage files, registering as a new business, and more. Phase Two of MiUI for Benefits will go live later, so for a short period of time employers and TPAs will perform tax functions in MiUI and benefits functions in the current MiWAM system.
Note: In MiUI, all employer representatives such as Professional Employer Organizations (PEO), fiscal intermediaries, and those with Power of Attorney (POA) will be classified as a third-party administrator (TPA).
To stay up to date with MiUI, sign up for the UIA’s free Michigan Employer Advisor newsletter. Readers of the Advisor will automatically receive the MiUI Minute newsletter, which provides regular updates about the new system.
