Count the employer before a qualifying event occurs
A founder may select a group health plan when the company has a small team and continue assuming federal COBRA does not apply as staffing grows. The threshold is not simply the number of people currently enrolled in insurance. Begin with the employer’s employee counts during the prior calendar year and the applicable counting rules. A part-time worker who declines coverage may still matter to the threshold analysis.
The Department of Labor explains that COBRA generally applies to private-sector group health plans of employers with at least twenty employees on more than half of typical business days in the previous calendar year, with part-time employees counted fractionally. The business should prepare that calculation before a termination, reduction in hours or other event creates an urgent continuation-coverage question.
Calculate the part-time contribution
Suppose full-time work is forty hours weekly and the company has eighteen full-time employees plus six employees working twenty hours each. Under a simplified fractional illustration, each part-time worker contributes 0.5 and the six together contribute three full-time equivalents for the count. The resulting daily count is twenty-one, not eighteen and not twenty-four. The actual annual threshold analysis must then consider the relevant business days and complete employer facts.
If the company had that staffing pattern on 140 of 250 typical business days, the pattern occurred on 56% of those days. That arithmetic flags a threshold issue under the assumed facts. It is not a complete coverage determination because related employers, plan status and the exact counting method may matter. Preserve the daily or otherwise adequately supported historical data rather than choosing a single year-end headcount.
Build a repeatable annual count
Use payroll records to identify employment dates, full-time schedules, part-time hours and changes during the year. Ask the benefits administrator which related employers or employee categories must be included under the applicable rules. A separate legal entity or separate payroll account should not automatically be excluded without examining the employer rules. Keep the method and assumptions with the calculation so that another administrator can reproduce the result.
Reconcile the count with the employee roster used for benefit administration. A coverage roster may omit employees who waived insurance, while a payroll roster may include people who are not relevant in the same way. Explain differences rather than forcing the two lists to match. The owner’s own status should also be analyzed under the applicable rules, not assumed from the fact that the founder receives a W-2.
Assign notice and event responsibilities
If COBRA applies, identify the plan administrator and the people responsible for receiving event information, issuing notices and tracking elections and premiums. Payroll should promptly communicate terminations and reductions in hours through the agreed process. A manager’s knowledge that an employee left is not necessarily the administrator’s receipt of the required event information. Use a dated handoff that identifies the plan and affected people.
The founder’s own reduction in hours or departure can also create a benefit-administration question separate from ownership. Do not assume continued share ownership automatically preserves active-employee coverage. Review the plan terms and applicable continuation rules before promising the owner or family uninterrupted coverage on the same basis. Keep any state continuation requirements in a separate checklist because a federal small-employer exception does not necessarily end every coverage obligation.
Review growth before the next plan year
Complete the employee-count review annually and whenever the employer structure changes in a way that affects the analysis. Give the conclusion and effective period to payroll, human resources and the benefits administrator. If the company previously used the wrong assumption, preserve the historical count and identify affected events before attempting correction. A new service agreement does not by itself resolve missed prior notices.
This article does not determine whether a particular plan or event is subject to COBRA, calculate every notice deadline or resolve acquisition responsibilities. It focuses on the prior-year employee threshold and the records needed to apply it. The useful decision is to establish the employer’s status before a coverage event occurs, so a growing owner employer can administer employee and family benefits using a verified count rather than an outdated impression of company size.
