Michigan unemployment system shuts Nov. 2 and employers must act first

Plenty of employers have not got there yet. According to the Detroit Regional Chamber, about 23,165 Michigan employers, roughly 10 percent of businesses in the state, had not activated their MiUI accounts as of August 14, 2026, despite UIA reminders that date back to at least July.

Employers that use a TPA face more tasks. They must associate the TPA with their MiUI account so it can file the quarterly wage report on their behalf, and the UIA notes that report is required even when an employer has no employees or wages to report. MiUI also introduces two benefits permissions, “Edit Claims Forms Mailing” and “Edit Benefit Charges.” The UIA has warned that TPAs holding existing tax-related permissions may not receive the new roles automatically. Employers must assign them manually through MiUI University before November 9, or those administrators will not be able to manage benefits functions at launch.

Why the cost stakes are higher than a routine system change

Michigan’s maximum weekly unemployment benefit has climbed under legislation signed in December 2024, from $362 to $446 in April 2025, then to $530 on January 1, 2026, with $614 scheduled for January 1, 2027. Each increase raises the cost of a charge that goes unchallenged, and an employer locked out of MiUI cannot protest an improper charge in time.

Claims activity tends to follow the labor market, and US job growth slowed to 29,000 in September as unemployment rose. That leaves little room for blind spots in claims handling. Administrative slips carry a price as well, with EY analysis finding payroll errors cost organizations $289,722 per 1,000 employees a year.

State rules on claim timing are also moving elsewhere, as a pharmacy overtime fight halved Pennsylvania’s wage claim window. Michigan’s switch is a reminder that deadlines tied to a platform can be as unforgiving as those written into statute.
