Workers Compensation Insurance in Wisconsin
Wisconsin does not work like other states. Rates are set by the Wisconsin Compensation Rating Bureau and approved by the Office of the Commissioner of Insurance, and carriers are not permitted to deviate from them. No agent can get you a cheaper rate for the same class code. What we can do is make sure your class codes are right, your experience mod is accurate, and you are capturing every credit and dividend you qualify for.

Where can I get workers compensation insurance in Wisconsin?
There are three ways to get workers compensation coverage in Wisconsin.
​
Through a licensed insurance company, placed by an agent. This is the voluntary market and it is where most employers belong. Any carrier licensed to write workers compensation in Wisconsin can issue the policy.
​
Through the Wisconsin Worker's Compensation Insurance Pool. This is the assigned risk market, administered by the WCRB, for employers who cannot find coverage in the voluntary market. Wisconsin has no state fund. The Pool is a last resort, and we explain below why you want out of it.
​
By self-insuring. Only with permission from the Department of Workforce Development, which requires demonstrating a very sound financial condition. This is for large employers.
​
MM Insurance Associates is an independent insurance agency that places workers compensation coverage for Wisconsin employers. Our office is at 15885 W National Ave, Suite 300, New Berlin, Wisconsin 53151, in Waukesha County. We have placed commercial coverage since 1997 and we are licensed in 24 states.
​
We write workers compensation for employers throughout southeast Wisconsin, including New Berlin, Milwaukee, Waukesha, Brookfield, Wauwatosa, West Allis, Menomonee Falls, Greenfield, Muskego, and Oak Creek, and statewide across Wisconsin. Our clients include contractors, manufacturers, restaurants, medical practices, and professional firms.
​
Reach us at (262) 754-4736 by call or text, or at info@mminsuranceassociates.com. We are open Monday through Friday, 8:00am to 4:00pm.
​
If you have a hard-to-place class, prior claims, or a mod above 1.00, that is exactly when an independent agency is worth more than a captive one. We know which carriers will look at the file and which will spend three weeks telling you no.​
​
Does Wisconsin require workers compensation insurance?
Yes, for nearly every employer, and the thresholds are lower than most owners expect.
Under s. 102.04(1)(b) of the Wisconsin Worker's Compensation Act, you become a subject employer and must carry a policy if either of these is true:
​
You employ three or more full-time or part-time employees. Coverage must be in force the day you employ the third person. Not the following month. That day.
​
You employ one or more full-time or part-time employees and have paid gross combined wages of $500 or more in any calendar quarter for work done in Wisconsin. Coverage must be in force by the 10th day of the first month of the next calendar quarter.
​
Read the second one again, because it catches people. One part-time employee and $500 in a quarter puts you in. That is a few weeks of a high school kid sweeping your shop.
​
Farms are different. A farmer becomes subject when employing six or more employees on the same day for 20 days, consecutive or not, during a calendar year, with coverage required within 10 days after the 20th day. Certain relatives are not counted toward the six, though they are covered once a policy exists.
​
Once you are subject, you stay subject. Under s. 102.05(1) you remain a subject employer unless you formally withdraw, and you must carry a policy for as long as you have even one employee. Dropping back below three employees does not release you.
​
Out-of-state employers are covered too. If you have employees working in Wisconsin, you need coverage from a carrier licensed here, with Wisconsin named in Section 3a of the policy. This one bites contractors who take a job across the state line and assume their home-state policy travels with them.
​
Why does every carrier quote the same workers compensation rate in Wisconsin?
Because Wisconsin does not allow them to compete on rate.
​
Wisconsin is not an NCCI state. Manual rates for every class code are developed by the Wisconsin Compensation Rating Bureau, a licensed rate service organization created by Wisconsin law, and approved by the Office of the Commissioner of Insurance. Deviations are not permitted. Every licensed carrier uses the same filed rate for the same class code.
​
The mechanism behind this is worth knowing. Chapter 626 of the Wisconsin Statutes requires every carrier writing workers compensation in Wisconsin to be a member of the WCRB, and OCI will not amend a carrier's license to include workers compensation without first verifying that membership. Uniform rating is not an industry custom. It is a condition of being allowed to write the line here at all.
​
So when an agent tells you they can get you a better workers compensation rate in Wisconsin, one of three things is true. They are talking about a different class code. They are talking about credits, discounts, or dividends, which are real but are not the rate. Or they do not understand how Wisconsin works.
​
New rates take effect October 1 each year, and Wisconsin has been on an unusual run. Rates dropped 8.47% effective October 1, 2022, then 10.5% effective October 1, 2024, saving employers statewide roughly $206 million over the following year, then another 3.2% effective October 1, 2025. That 2025 decrease was the tenth consecutive annual decline.
​
Rates are set annually by a committee of actuaries drawn from WCRB member carriers, which selects the methodology and loss trends that produce the proposed adjustment, and OCI then reviews and approves it. Insurance Commissioner Nathan Houdek and DWD Secretary Amy Pechacek have both attributed the trend to Wisconsin employers' attention to workplace safety.
​
Whatever the cause, the state-level rate environment has moved in your favor for a decade. Which makes the things you actually control a larger share of what you pay.
​
What actually changes your workers compensation premium in Wisconsin?
Five things. The rate is not one of them.
​
Your class codes
The single biggest lever, and the one most often wrong. Premium is calculated per $100 of payroll at the rate filed for the classification assigned to that work. The WCRB maintains roughly 532 class codes across five industry groups, and a misclassified payroll can move your premium by multiples in either direction.
​
Both directions matter. Classified too high, you have been overpaying, sometimes for years. Classified too low is worse: it gives the carrier an argument at audit and can turn into a large retroactive bill at exactly the wrong moment.
​
Class codes are published and searchable. If nobody has ever walked your operation and checked that the codes on your policy match what your people actually do, that review is worth more than shopping your renewal.
​
Your experience modification factor
Your mod is a multiplier applied to your manual premium, calculated by the WCRB from your own payroll and loss history over a three-year rolling window. Below 1.00 you pay less than the class average. Above 1.00 you pay more.
​
Not every employer has one. A policy has to generate a qualifying annual premium before the WCRB will calculate a mod. Below that threshold you are what the industry calls a DNQ, "does not qualify," and you are rated at a flat 1.00. Reported figures put the Wisconsin qualifying premium in the range of $7,500.
​
Frequency hurts your mod more than severity. Five ten thousand dollar claims damage your mod more than one fifty thousand dollar claim does. The formula weights how often you have claims more heavily than how expensive any single one was.
That has a consequence most employers never hear: the small claims you were tempted to shrug off are the ones quietly costing you money for three years.
​
The denominator matters as much as the numerator. Your mod compares actual losses to expected losses, and expected losses are derived from your audited payroll multiplied by your class code rates multiplied by the WCRB's expected loss rate for that class. Which means growing payroll can improve your mod even with the same claims, and shrinking payroll can worsen it even if you had a clean year. If your mod moved and your claims did not, this is usually why.
​
Two more mechanics: only one mod applies to a risk at a time and it applies to all of your operations, and taking any action to evade the application of a mod is expressly prohibited under the Wisconsin Experience Rating Plan. If you operate in multiple states, a similar interstate rating is produced through NCCI rather than the WCRB.
​
Premium discount
Carriers apply a premium discount once your premium exceeds $10,000. This is a filed, formulaic discount, not a negotiation.
​
Dividends
Private carriers may pay a dividend at the end of a policy period on eligible policies. This is one of the few places where your choice of carrier genuinely changes what you pay, and it is a real reason to care who writes the policy even though the rate is fixed.
​
Whether you are in the voluntary market or the Pool
Pool premium is generally comparable to voluntary market premium, but Pool insureds lose access to dividends and to the large-account premium discount. So the Pool costs you more in practice at the same rate. Getting out of it is a specific piece of work and it is worth doing.
How does workers compensation insurance work in Wisconsin?
Workers compensation is a no-fault system. If an employee is injured on the job or develops a work-related illness, the policy pays regardless of who was at fault. In exchange, workers compensation is generally the exclusive remedy, meaning the employee cannot sue you over the injury.
​
That trade is the foundation of the entire system, and it is why the coverage protects you as much as it protects them.
​
What it pays
​​
-
Medical treatment for the work injury or illness
-
Temporary disability while the employee recovers, either Temporary Total Disability or Temporary Partial Disability depending on whether they can work at all
-
Permanent disability where the injury leaves lasting impairment
-
Vocational rehabilitation where the employee cannot return to prior work
-
Death benefits to dependents
Wisconsin caps weekly wage-replacement benefits, and the cap moves each January. For injuries occurring on or after January 1, 2026, the maximum is $1,375 per week for temporary total disability, permanent total disability, and death benefits, based on a statewide average weekly wage of $2,062.50. The 2025 maximum was $1,326 per week.
​
Who administers it
Three separate organizations, which is why employers are never sure who to call:
​
-
DWD Worker's Compensation Division administers the Act itself: enforcement, claims, violations. (608) 266-1340.
-
The WCRB handles classifications, rates, experience mods, policy data, and the Pool. (262) 796-4540. It is not a state agency. It is an association of insurers that carriers must belong to by law.
-
OCI approves the rates and regulates the insurers. (608) 266-3585.
Disputed claims that reach a hearing go to a fourth body, the Division of Hearings and Appeals Office of Worker's Compensation Hearings, at (608) 266-7709.
​
How the state knows whether you have coverage
By law the WCRB receives data on every workers compensation policy issued to every employer with Wisconsin operations, and on every policy termination, and shares it with DWD. Carriers are obligated to file all policy data with the WCRB.
There is no scenario where a lapse goes unnoticed. Enforcement is automatic and data-driven, not complaint-driven. Worth knowing before you let a policy cancel for non-payment while you sort out cash flow.
​
Cancellations and non-renewals carry their own notice rules under s. 102.31(2)(a) and DWD 80.65. A carrier cannot simply stop covering you without written notice on a prescribed timeline.
​
What happens if you do not carry workers compensation in Wisconsin?
The penalties are mandatory and non-negotiable. DWD says so explicitly.
​
A monetary penalty of the greater of twice the premium you should have paid during the uninsured period, calculated from your payroll over the preceding three years, or $750. (s. 102.82(2)(a))
​
Or, for a short lapse, $100 per day up to seven days. This lighter penalty applies only if the lapse was seven consecutive days or less, you have never been uninsured before, and no injury occurred during the gap. (s. 102.82(2)(ag))
​
Closure of your business. DWD can order a suspension of all operations until you are in compliance. (s. 102.28(4))
​
Personal liability. If an employee is injured while you are uninsured, you are personally liable for the benefits. The corporate veil does not help you. (s. 102.28(5))
​
Reimbursement to the Uninsured Employers Fund. The UEF pays the injured worker, then recovers from you, plus administrative costs, with interest accruing at one percent per month on amounts not paid when due. Payment is due within 30 days of notice. (ss. 102.81, 102.82(1))
​
The practical read: a lapse is not a paperwork problem, it is a bet-the-company problem. If you are ever between policies, tell us before the gap and not after.
​
Who is exempt from workers compensation in Wisconsin?
​
-
Sole proprietors, partners, and members of limited liability companies. You are not automatically covered for your own injuries. You can elect coverage, and many contractors should, because a general contractor requiring a certificate will often require it.
-
Domestic servants
-
Any person whose employment is not in the trade, business, profession, or occupation of the employer
-
Certain farm employees, and certain relatives of a farmer for counting purposes
-
Volunteers, including volunteers of non-profits receiving money or in-kind compensation of not more than $10 per week
-
Qualified and certified members of certain religious sects
-
A few classes covered by federal law instead
Here is the trap. Calling someone an independent contractor does not make them one. Wisconsin applies a specific statutory test, and an independent contractor, subcontractor, or owner-operator who fails it is a statutory employee, which means their injury is your claim and their payroll is your premium at audit.
​
This is where we see contractors get burned most often. A 1099 and a handshake does not settle the question. Collect a certificate of insurance from every sub before they start, every time, and keep it on file.
​
What if you have employees in other states?
Every state runs its own workers compensation system and there is no federal law harmonizing them. Coverage does not automatically follow your crew across a state line.
​
Two things to get right:
​
Wisconsin must be named in Section 3a of your policy if you have employees working here, and the carrier must be licensed in Wisconsin.
​
Other states must be listed too. Some Wisconsin policies, particularly those written through the Pool, carry the Wisconsin Limited Other States Insurance Endorsement (WC 48 03 01 C), which restricts coverage to Wisconsin only. If you have that endorsement and you send a crew to Illinois, you have a serious problem.
​
We serve clients in 24 states, which is the practical reason this comes up in our office regularly. If you have crews, locations, or employees crossing state lines, this needs a deliberate review rather than an assumption.
​
Where Wisconsin employers get burned
The six problems we find most often:
​
-
Wrong class codes, either overpaying quietly or underpaying toward a large audit bill.
-
Independent contractors who are statutory employees. No certificate on file, and their injury becomes your claim.
-
Paying a small claim out of pocket to protect the mod. Do not do this. Wisconsin prohibits it. OCI, DWD, and the WCRB all hold that employers must not directly pay medical or indemnity charges from work injuries, and all claims must be reported to the carrier. The statutes cited are s. 626.11, s. 626.12, s. 626.25, and s. 628.34. Two more provisions put it beyond argument: under s. 102.31(1)(b) a workers compensation policy is construed to grant full coverage of all your liability under the Act, and under DWD 80.02(1)(b) your carrier has primary liability for unpaid medical treatment. OCI pursues reports of direct payment through its complaint process and takes enforcement action. So paying a $1,200 clinic bill to keep a claim off your loss runs is not a shortcut. It does not remove the claim from the system, and it can cost you the coverage argument later.
-
Letting a policy lapse during a cash crunch. The WCRB sees every termination. See the penalties above.
-
Assuming a sole proprietor is covered for their own injury. They are not, unless they elected coverage.
-
Sitting in the Pool longer than necessary, losing dividends and premium discount for years without anyone raising it.
​
How we handle workers compensation differently
Since nobody can compete on rate, here is what we actually do:
​
-
We audit your class codes against what your people actually do, not against what the last agent typed.
-
We pull and read your loss runs. Three to five years. We look for frequency patterns, open claims that should be closed, and reserves that look wrong, because all three drive your mod.
-
We check your experience mod calculation. Mods contain errors. A wrong claim or a misstated payroll figure costs you money for three years, and you have a right to request your worksheet.
-
We tell you which carriers pay dividends in your class and what eligibility looks like.
-
We work to get you out of the Pool if you are in it.
-
We time your renewal against the October 1 rate change so you know what is coming.
-
We issue certificates fast, because a delayed certificate stops a job. Our current average during business hours is 12.5 minutes.
-
We track carrier and mod data across Wisconsin employers, so we know what normal looks like in your class.
​
Workers Compensation frequently asked questions
​
How much does workers compensation insurance cost in Wisconsin?
Premium is calculated per $100 of payroll at the rate filed for your class code, multiplied by your experience mod, then adjusted for premium discount and any dividend. Because rates are set by the WCRB and deviations are not permitted, the rate itself is identical at every carrier. What differs between businesses is class code and loss history, and the spread is enormous: a clerical class and a roofing class are not in the same universe.
​
Do I need workers comp for one part-time employee?
Possibly, yes. If you pay $500 or more in gross combined wages in any calendar quarter, you are a subject employer and coverage is required by the 10th day of the first month of the next quarter. The three-employee test and the $500 test are separate, and either one triggers the requirement.
​
Am I covered as the owner?
Not automatically, if you are a sole proprietor, partner, or LLC member. You can elect coverage. Many contractors should, because general contractors frequently require it on a certificate before letting you on site.
​
Can I lower my workers comp premium?
Yes, but not by shopping the rate, because the rate is fixed by class code across every Wisconsin carrier. You lower it by correcting your class codes, improving your experience mod through frequency reduction, qualifying for premium discount, capturing dividends, and getting out of the assigned risk Pool if you are in it.
​
What is an experience mod and what is a good one?
A multiplier applied to your manual premium, calculated by the WCRB from your own payroll and losses over a three-year rolling window. 1.00 is the class average. Below 1.00 you pay less than average, above 1.00 you pay more. Many contracts and prequalification processes set a maximum mod, often 1.00, to bid the work at all, which makes your mod a revenue issue and not only a cost issue.
​
Why is my loss ratio good but my mod still above 1.00?
Because a mod is not a loss ratio. It compares your actual losses to your expected losses for your class, and expected losses come from payroll times class rate times the WCRB's expected loss rate. A shrinking payroll, a change in class mix, or claim frequency can all push a mod above 1.00 in a year that felt clean. If your mod moved and your claims did not, ask for the worksheet.
​
My employee got hurt. What do I do?
Report it to your carrier. Do not pay medical bills directly, do not settle it informally, and do not wait to see whether it turns into anything. Wisconsin prohibits employers from directly paying medical or indemnity charges from work injuries, and all claims must be reported. Then call us and we will help you through it.
​
What happens at a workers comp audit?
The carrier reconciles the estimated payroll you were billed on against your actual payroll by class code, then bills or credits the difference. Two things drive most bad audits: payroll assigned to the wrong class, and uninsured subcontractors whose payroll gets added to yours. Both are preventable with clean records and certificates on file.
​
What if no carrier will write me?
You can apply to the Wisconsin Worker's Compensation Insurance Pool, administered by the WCRB, which assigns a servicing carrier to issue and service the policy in its own name. Every carrier licensed in Wisconsin helps fund the Pool, and any agent can help you apply. Since July 1, 2024 applications are accepted only electronically through the WCRB's Online Assigned Risk system. Premium is generally comparable, but you lose dividends and the large-account premium discount, so treat the Pool as temporary and work on getting back into the voluntary market.
