Advocacy News – Jan. 13, 2026
What’s new: The Michigan Unemployment Insurance Agency (UIA) is replacing the Michigan Web Account Manager (MiWAM) with a new tax and benefits system, MiUI. The tax functions go live Monday, Feb. 23.
Why it matters: When phase one of MiUI for tax goes live, employers and third-party administrators (TPAs) will use the new platform for tax functions such as filing quarterly wage and tax reports, uploading wage files, registering as a new business, and more.
- Phase two for benefit will launch later, meaning there will be a short period when tax functions are handled in MiUI while benefits functions remain in MiWAM.
What’s next: The UIA recommends employers take these five steps now to ensure a smoother launch and uninterrupted reporting:
- Set up system administrators and users. Ensure all future administrators and any other users for your Employer/TPA have a MiLogin for Business account.
- Verify MiWAM access. Confirm you can log in and have key details ready, including your MiUI Activation Code, to start your MiUI account.
- Update your account info. Check and update contact details, payment methods and user permissions in MiWAM.
- Review your current TPA-employer associations and role assignments to understand what roles the TPAs will have in MiUI.
- Prepare wage reporting. Review MiUI wage report formats and test files with the Wage Report File Validation tool before your first submission.
