A Wisconsin corporation, whether a C-corp or an S-corp, generally needs workers compensation, because its officers are treated as employees by default and are counted toward the three-employee threshold. This is the opposite of how LLCs and sole proprietors work: where those owners are left out, corporate officers are counted in, so even a small family corporation can be over the line on its officers alone.
Who this is for: Owners and officers of a Wisconsin corporation trying to work out whether officers are covered, whether they can opt out, and when the corporation must insure.
The short version
- Corporate officers are employees by default and are covered by the policy.
- Officers count toward the three-employee threshold, unlike LLC members and sole proprietors.
- An officer can opt out only in a small, closely held corporation, and the opt-out is narrow.
- An officer who opts out of coverage still counts toward the threshold.
- Once you cross a threshold, all your non-officer employees must be covered too.
Officers are counted in, not left out
The table below is the whole reason a corporation is different from an LLC in Wisconsin.
| Person | Counts toward the three? | Covered by default? |
|---|---|---|
| Corporate officer | Yes | Yes |
| Officer who has elected out | Yes, still counts | No |
| Regular employee | Yes | Yes, once over a threshold |
| Part-time or seasonal employee | Yes | Yes |
| LLC member (for contrast) | No | No |
The narrow way an officer opts out
Wisconsin only lets officers opt out in a genuinely small corporation. The corporation must have no more than 10 stockholders, and no more than two officers may elect not to be subject. If the corporation has a policy, each opting-out officer is named by an endorsement on that policy, and the election runs for the policy period and cannot be reversed in the middle of the term. If the corporation has no more than 10 stockholders, no more than two officers, no other employees, and is not otherwise required to insure, an officer can instead file a notice with the Worker's Compensation Division. The trap that catches people is that the opted-out officer still counts toward the three-employee threshold, so opting out lowers your premium but does not lower your headcount.
Why the count matters even for a two-person corporation
Because officers count, a corporation with three officer-owners and no other staff is already at the three-employee threshold and must insure, even if each officer would rather opt out. And once you are over the line, your score based on past claims, called the experience modification rate, starts to move your price up or down, so it pays to classify payroll correctly and manage claims from day one.
A Waukesha example
Illustrative, not a quote. A small manufacturing corporation in Waukesha has two officer-owners and two machine operators. The two officers plus two operators put the corporation at four people who count, well over the three-employee line, so it must carry comp. The two officers consider opting out to trim premium, and because the corporation has fewer than 10 stockholders and only two officers, they can, by endorsement on the policy. But the operators must still be covered, and the officers still count toward the threshold. We review the class codes on the shop payroll so the operators are not rated as something more expensive than they are. See our workers comp for manufacturers page.
Real questions Wisconsin owners ask
Does my Wisconsin corporation need workers comp?
Usually yes. Corporate officers are treated as employees and counted toward the three-employee threshold, so even a small corporation is often over the line on its officers alone.
Are corporate officers covered by the policy in Wisconsin?
Yes, by default. Unlike LLC members and sole proprietors, corporate officers are included on the corporation's workers comp policy unless they formally elect out.
Can a corporate officer opt out of coverage?
Only in a small corporation. It must have no more than 10 stockholders, and no more than two officers may elect out, usually by an endorsement on the policy.
If an officer opts out, does the corporation still need coverage?
Very possibly. An officer who opts out still counts toward the three-employee threshold, and any non-officer employees must be covered once you cross a threshold.
Do officers count toward the three even after opting out?
Yes. This is the Wisconsin trap. Opting out removes an officer from coverage but not from the headcount, so it lowers premium, not your employee count.
We are three officer-owners with no other staff. Do we need it?
Yes. Three officers who count means you are at the three-employee threshold, so the corporation must carry a policy even if each officer would prefer to opt out.
What lowers a corporation's workers comp price over time?
Correct payroll classification and a clean claims record. Your score based on past claims, the experience modification rate, rises or falls with your history and directly changes your premium.
Why Wisconsin owners choose Morrow
- We shop the right market for you. Wisconsin has no state fund, so you buy from private insurers competing for your business, and because every carrier starts from the same state-set manual rates filed by the Wisconsin Compensation Rating Bureau, we compete for you on your work categories, dividends, and safety credits rather than a lower base rate, with the state's guaranteed-issue pool as a backstop if you are hard to place.
- We catch pricing mistakes. Your price depends heavily on the category your work falls into for pricing (the class code). Put people in the wrong category and you overpay for years. We review your payroll and classifications before you buy.
- Proof of coverage, fast. Need a certificate (proof of coverage) for a general contractor or a landlord before Monday? We turn those around the same business day for most carriers.
- We help lower the score that drives your price. Insurers give you a score based on your past claims that raises or lowers your cost (the experience modification rate). We review it each year, flag errors, and connect you with return-to-work and safety resources that bring it down.
- Real people when a claim happens. When someone gets hurt, we stay involved through the life of the claim, not just at renewal.
