Look at the fall calendar of almost any Michigan employer with a January 1 renewal date, and the same pattern shows up. The workers’ comp carrier wants updated payroll figures, the health plan needs final elections, and employees have questions about both. That overlap is what sets Q4 business prep in Michigan apart from every other quarter.
Neither task is the real problem on its own. The problem is that most small and mid-size businesses run them on separate tracks, with a broker handling the policy and someone in the office handling enrollment. When headcount or job roles change in the fall, one side hears about it and the other doesn’t, and that’s where coverage gaps and missed compliance deadlines start.
DynamicHR takes a different approach. As a PEO, we manage your workers’ compensation coverage and your employee benefits enrollment together, on one calendar, with one team watching every deadline. Renewal pricing, coverage review, and open enrollment readiness all happen in a single conversation instead of three.
Why Workers’ Comp Renewal and Open Enrollment Collide in Q4
For many Michigan businesses, the workers’ comp policy and the group health plan both renew on January 1. That puts renewal quotes, payroll estimates, carrier conversations, and employee enrollment into the same eight to ten week window.
Each process usually has its own owner. The broker asks for payroll projections and claims history. The benefits contact builds enrollment materials and chases employee elections. Neither one sees the other’s timeline, and when headcount or job roles change, that information often reaches one side and never the other.
The results are predictable: workers’ comp premiums based on outdated payroll figures, benefit eligibility that no longer matches who is actually on staff, and an owner fielding the same questions twice. Q4 business prep in Michigan goes more smoothly when both processes start from the same data.
Michigan’s Workers’ Compensation Requirements, in Plain English
Michigan’s Workers’ Disability Compensation Act, at MCL 418.115, requires coverage for private employers that regularly employ three or more people at one time. It also covers smaller employers when at least one employee has worked 35 or more hours per week for 13 weeks or longer during the preceding 52 weeks.
Corporate officers and LLC members are generally counted as employees for this purpose, although Michigan allows certain owners to elect out of coverage. Part-time and seasonal workers count toward the threshold as well, which catches some growing businesses off guard during their busiest months.
Coverage can come from a private carrier, approved self-insurance, or a PEO’s master policy. The PEO route can also change how premiums are paid, which we explain in workers’ comp without the upfront deposit. Michigan uses its own rating organization, the Compensation Advisory Organization of Michigan (CAOM), to calculate experience modification factors for many employers in the state.
What to Review Before Your Workers’ Comp Policy Renews
Start with payroll by classification. Workers’ comp premiums are built on class codes and the estimated payroll in each one. If the mix of office and field staff has shifted, or you added a new line of work, the renewal quote needs to reflect it. Overestimating payroll ties up cash in premium. Underestimating it creates a bill at the annual payroll audit.
Next, review your experience modification factor. Your claims history directly affects your rate, so confirm that closed claims are reported as closed, check reserves on any open claims, and ask how the new mod was calculated.
Finally, confirm the coverage details: employer’s liability limits, certificates of insurance from any subcontractors, and whether owners are included or excluded. A workers’ compensation renewal in Michigan is the right moment to fix classification errors before they carry into another policy year.
Getting Open Enrollment Right Before the December Deadline Crunch
Most employers with calendar-year plans run open enrollment between October and early December. Work backward from January 1: the carrier’s deadline for final elections, the time needed to load those elections into payroll, and the time needed to confirm them with employees.
Before materials go out, check eligibility against current headcount and hours. Part-time employees who have picked up hours, new hires in a waiting period, and employees returning from leave are the groups most often missed. Any changes to plan design, contribution levels, or carriers should be explained in plain language so employees aren’t surprised by their first January paycheck.
Include retirement benefits in the conversation. Open enrollment is a natural time to remind employees to review their 401(k) plan deferral elections for the new year.

COBRA and Compliance Deadlines You Can’t Afford to Miss
Federal COBRA applies to group health plans sponsored by employers with 20 or more employees. After a qualifying event, such as a termination or a reduction in hours, the employer has 30 days to notify the plan administrator, and the administrator then has 14 days to send the election notice. When the employer is also the plan administrator, the combined window is 44 days.
Missing that window is expensive. Under Section 4980B of the Internal Revenue Code, the IRS excise tax is $100 per day for each affected qualified beneficiary, capped at $200 per day when more than one family member is affected by the same event. Employers are required to self report the tax on IRS Form 8928, and ERISA allows separate penalties and lawsuits from affected individuals on top of it.
Q4 tends to be heavy on qualifying events as seasonal roles end and schedules change, so notice tracking can’t slip during enrollment season. Employee benefits compliance in Michigan also includes ACA reporting for applicable large employers early in the new year and up-to-date plan documents. The DynamicHR Benefits Compliance Guide covers those obligations in more detail.
How Bundling Workers’ Comp and Benefits Simplifies Q4
When one partner manages both, the payroll data behind your workers’ comp premium and your benefits eligibility come from the same system. New hires, terminations, and hours changes update both at once, and a termination triggers the COBRA process instead of depending on someone to forward an email.
Under DynamicHR’s PEO model, employees are covered by a master workers’ compensation policy and a combined benefits program. That often gives small and midsize businesses access to pricing and plan options that are difficult to get on their own, with renewal pricing, coverage adequacy, and enrollment readiness reviewed in the same conversation.
The biggest change is the calendar. Instead of a broker’s renewal timeline and a separate enrollment timeline competing for attention, there’s one schedule, one team, and one set of deadlines to track through year-end.
Frequently Asked Questions
Is workers’ compensation insurance required in Michigan?
In most cases, yes. Michigan’s Workers’ Disability Compensation Act requires coverage for private employers that regularly employ three or more people at one time, or one employee working 35 or more hours per week for 13 weeks or longer within the preceding 52 weeks. Corporate officers and LLC members are generally considered employees for this purpose, although certain owners can elect an exclusion.
When does open enrollment usually happen?
Most Michigan employers with calendar-year benefit plans run open enrollment sometime between October and early December, so new elections take effect January 1. That window overlaps directly with workers’ comp renewal season for many businesses, which is exactly why the two processes benefit from being planned together rather than on separate tracks.
What happens if I miss a COBRA notice deadline?
After a qualifying event, such as a termination, the employer generally has 30 days to notify the plan administrator, and the administrator has 14 days to send the COBRA election notice. Missing that window can trigger an IRS excise tax of $100 per day for each affected qualified beneficiary, up to $200 per day per family. Separate ERISA penalties and lawsuits from affected individuals are also possible.
Can workers’ comp and benefits be managed by the same provider?
Yes. DynamicHR administers workers’ compensation coverage and employee benefits under the same PEO agreement, which means renewal dates, enrollment deadlines, and compliance notices are tracked by one team on one calendar. This removes the coordination gap that happens when a broker handles workers’ comp and a separate benefits administrator handles enrollment.
One Q4 Calendar Instead of Two
Workers’ comp renewal and open enrollment don’t have to be two separate scrambles that happen to land in the same quarter. When one team manages both, coverage decisions and benefits elections get made with the full picture in view, not in isolation.
If your business is heading into Q4 juggling a workers’ comp broker and a separate benefits process, start by reviewing our workers’ compensation coverage options, then pair that with employee benefits built for the same renewal calendar. Our team can walk through both before your Q4 deadlines close in.
