MiUI is now live for employers and TPAs to perform all tax and benefits functions -- such as filing quarterly wage and tax reports, uploading wage files, registering as a new business, and more.
This page provides helpful information, links, and resources about what employers and third-party administrators (TPAs) need to know about MiUI.
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.
