Wisconsin Workers’ Compensation Rules for Employers
Wisconsin requires workers’ compensation at the third employee or $500 in quarterly wages. Who is excluded, where to buy, injury deadlines and penalties.
Wisconsin Workers’ Compensation
Two separate triggers for coverage, who sits outside the Act, and the clocks that start the day someone gets hurt
A Wisconsin owner asked me once whether he had until the end of the month to get a policy in place. He had two people on payroll and a third starting on Monday. He had until Monday.
Wisconsin does not phase the duty in. It attaches on a specific day, and it can attach on two separate tracks. Most owners know about the headcount track and have never heard of the payroll track, which catches a business with one part-time employee and a $500 quarter.
This page covers one state. How the system works in general, and why the exclusive remedy bargain exists at all, sits in our guide to workers’ compensation insurance. Hiring, wages and leave belong to the Wisconsin HR compliance guide.
Who Has to Carry Coverage
Wisconsin sets two triggers for ordinary employers and a third for farms. The Department of Workforce Development lays them out on its insurance requirements page, which restates section 102.04(1)(b) of the Wisconsin Statutes in plain terms.
The first trigger is headcount. Employ three or more full-time or part-time employees and coverage is required on the day you employ the third person. The second is payroll. Pay $500 or more in gross combined wages in any calendar quarter to one or more employees for work done in Wisconsin, and coverage is required by the 10th day of the first month of the next quarter.
Both counts are broader than owners expect. Minors count. Family members count outside farming. Part-timers count. Corporate officers count, including an officer who has excluded himself from the policy by endorsement.
| Trigger | When coverage must be in force | Source |
|---|---|---|
| 3 or more full-time or part-time employees | The day you employ the third person | 102.04(1)(b)1 |
| 1 or more employees and $500 or more in gross combined wages in a calendar quarter | The 10th day of the first month of the next calendar quarter | 102.04(1)(b)2 |
| Farming operation with 6 or more employees on the same day for any 20 days in a calendar year | 10 days after the 20th such day | 102.04(1)(c) |
| Out-of-state employer with employees working in Wisconsin | Same triggers, with a policy from a Wisconsin-licensed carrier naming Wisconsin in section 3-A | 102.28(2) per DWD |
| You already crossed a trigger, then dropped below it | Coverage stays required. You remain subject to the Act until you file a notice of withdrawal and the department approves it | DWD withdrawal guidance |
That last row is the one that catches seasonal businesses. Once you have been subject to the Act, laying everyone off does not reset you. The department requires a full calendar year under the thresholds, a filed notice of withdrawal and a 30-day wait before coverage can be dropped, and it says corporations cannot withdraw at all.
The department also points to case law behind the headcount rule. A 1947 Wisconsin Supreme Court decision held that employing three persons for a single moment makes an employer subject to the Act, and 2021 Wisconsin Act 232 wrote that result into the statute. There is no probationary window and no waiting period, and coverage begins on an employee’s first day of work.
Who Sits Outside the Act
Wisconsin defines an employee broadly and then names a short list of exceptions. Section 102.07(4)(a) covers every person in the service of another under any contract of hire, express or implied, and excludes only domestic servants and any person whose employment is not in the trade, business, profession or occupation of the employer.
The department sets out the full picture in its publication on employee coverage exceptions. The working version for a small business is below.
| Worker or setting | How Wisconsin treats it |
|---|---|
| Sole proprietor, partner, member of an LLC | Not an employee. Every policy excludes them unless it is specifically endorsed to include them, which they may buy voluntarily |
| Corporate officers | Employees. All policies covering a corporation include them, and a closely held corporation of no more than 10 stockholders may exclude up to 2 named officers by endorsement |
| A corporation with no more than 2 officers and no other employees | May stay outside the Act by filing a Corporate Officer Option Notice with the division. Any third officer or any other employee ends that option |
| Domestic servants in a private home | Excluded from the definition of employee. The employer may elect to cover them |
| Anyone whose work is not in the trade, business, profession or occupation of the employer | Excluded unless the employer elects coverage. This is Wisconsin’s version of the casual labor carve-out, and it turns on the employer’s business, not on how occasional the work is |
| Home-care providers hired directly by the person receiving care | Coverage is optional for that employer, because the work is not in a trade or business of the recipient |
| Farm laborers | Covered once the farm crosses 6 employees on 20 days. Certain relatives of the farmer are not counted toward the 6, including parents, spouse, child, siblings and in-laws |
| Independent contractors | Employees unless the person meets and maintains all 9 conditions of section 102.07(8). Agreement between the parties does not create contractor status |
| Volunteers | Not covered and cannot be covered, except that a non-profit may elect to cover a volunteer paid no more than $10 per week |
| Qualified and certified members of certain religious sects | Exempt only after the employer applies, the worker waives rights and the sect agrees to provide support, with a long-standing history presumed at 25 years |
| Employees of Native American tribal enterprises, including casinos | Outside the Act, because tribes are sovereign, unless the tribe waives immunity by voluntarily buying a policy |
| Real estate brokers, agents and salespersons meeting section 452.38 | Not employees of the firm unless the firm elects to name them under section 102.078 |
| Federal employees, interstate railroad workers, seafarers and dock workers | Covered by federal law rather than by chapter 102 |
Two rows do more damage than the rest. The first is the officer exclusion, because employers read it as a way to shrink the headcount. It is not. An officer who excludes himself is still an employee of the corporation and still counts toward the three-employee and $500 wage tests, a point the department makes on its corporate officers page.
The second is contractor status. Wisconsin requires all nine conditions of section 102.07(8) at once, including a separate business, a federal employer identification number or prior year business tax returns, specific contracts, responsibility for operating expenses, payment per contract or per job, and real exposure to profit and loss. Our explainer on what an independent contractor is covers the general distinction.
Where the Policy Comes From
Wisconsin employers buy from private insurance carriers, through an agent or directly from the company. The state does not run a fund and says so in one line on its page on how to buy coverage, which puts the number of carriers licensed to write the line in Wisconsin at about 300.
That matters if you compare notes with an employer in a monopolistic state, where a government fund is the only seller and employer’s liability protection has to be arranged separately. Wisconsin has no such gap. You buy the standard commercial workers’ compensation and employer’s liability policy from a licensed carrier, and the live question is which carrier writes you.
Two mechanics are specific to Wisconsin. The policy must be endorsed to name Wisconsin as a covered state in section 3-A, and the carrier must file it with the Wisconsin Compensation Rating Bureau. An all-states endorsement in section 3-C is not accepted as proof of Wisconsin coverage, which is the trap for an out-of-state company that just hired its first remote worker in Milwaukee.
If the open market turns you down, your agent applies to the Worker’s Compensation Insurance Pool. The rating bureau administers the pool as trustee, and the department is careful to note that the bureau is not a state agency. The pool is a residual market so that no employer is forced to operate uninsured, not a state fund.
Self-insurance is the third route, and for a company of five to fifty people it is background rather than a decision. The department’s page on considerations for self-insurance says outright that self-insuring is not practical below about $200,000 in annual premium.
| Self-insurance requirement | What Wisconsin asks for | Source |
|---|---|---|
| Who approves | The Department of Workforce Development, by written order exempting the employer from the duty to insure | 102.28(2)(b) |
| Financial history | Audited financial statements, including a CPA opinion, for at least the latest five years | DWD 80.60(4)(b)1 |
| Ongoing reporting | Financial statements each quarter, audited statements each year, annual claim payment reporting, and renewal every 3 years | DWD 80.60(4)(a) |
| Safety program | A copy of the employer’s current safety and loss control plan with the application | DWD 80.60(4)(b)5 |
| Security | At least $500,000, and the department adds 30 percent to that minimum if the security is anything other than a surety bond | DWD 80.60(4)(d)4 and 6 |
| Excess insurance | Catastrophic cover may be required by department order, written by a licensed excess carrier on approved forms | DWD 80.60(2) and (4)(d)3 |
| Fees | A non-refundable initial application fee set by the department, plus a $200 annual fee and a share of program administration costs | DWD 80.60(4)(ag) and (am) |
| Practical floor | The department states self-insurance is not practical under $200,000 in annual premium absent unusual circumstances | DWD self-insurance guidance |
Whichever route you take, keep the policy number and effective dates somewhere you can reach in a minute. A general contractor will ask before you set foot on a site, and coverage is public: the rating bureau runs a lookup that shows which carrier covered a given employer on a given date. If you operate in more than one state, our rundown of requirements by state shows how far apart the thresholds sit.
One more rule that surprises new employers. You pay for the coverage. Section 102.16(3) forbids withholding, deducting or collecting any part of the premium from employees, and an employee cannot waive the right to compensation even in writing.
Posters and What a Worker Receives
Wisconsin does not mandate a workers’ compensation poster and does not require a pamphlet at hire. Chapter 102 and the department’s rules in DWD 80 contain no posting requirement, and the workers’ compensation notice is not one of the sheets in the state’s mandatory workplace poster packet, which carries fair employment, family leave, minimum wage and unemployment notices instead.
That is the letter of it. The practice is different, and the reason sits in the notice rule. Section 102.12 says that if no representative has been designated by posters placed in one or more conspicuous places where notices to employees are customarily posted, notice of an injury received by any superior is sufficient. Post nothing and any supervisor becomes a valid place to report an injury, whether or not that report reaches you.
So the department publishes a notice built for exactly this. The Notice to Injured Workers and Employers, form WKC-19606-P, states that the state requires this employer to carry coverage, lists what the employee and the employer each do after an injury, and leaves blanks for the carrier or claim administrator name, address and telephone number. It comes in English, Spanish and Hmong.
Nothing stops you from covering the basics during onboarding either. Handing a new hire the carrier name, the reporting rule and the name of the person to tell is good practice even though no Wisconsin statute demands it. Wage and hour notices are a separate set, covered on the Wisconsin minimum wage page.
Injury Reporting Deadlines
Wisconsin runs three clocks after an injury, and only one of them is yours. The employee gives notice, you tell your carrier, and your carrier files with the state. The department sets out the employer side on its page on handling work injuries, and the reporting rule itself is DWD 80.02.
| Who acts | Deadline | Detail and source |
|---|---|---|
| Employee to employer | Immediately, and within 30 days | Actual notice must reach the employer, an officer, a manager or a designated representative. Absence of notice does not bar recovery if the employer was not misled by it (102.12) |
| Employee, outer limit | 2 years | No application filed within 2 years of the injury bars the right to compensation, except that the bar does not apply if the employer knew or should have known within that period, in which case DWD describes a 6-year limit |
| Employee, no limit cases | None | Occupational disease and the traumatic injuries listed in 102.17(4)(b) carry no statute of limitations. 2025 Wisconsin Act 145 added shoulder replacements and reverse shoulder replacements to that list |
| Employer to the division and the insurer, on a death | 24 hours | Report the death to the Worker’s Compensation Division and to the carrier by phone, fax, letter or other authorized means (DWD 80.02(1)) |
| Employer to its insurer, other injuries | 7 days | Required where disability exists beyond the third day after the employee leaves work, or the carrier has primary liability for unpaid medical treatment. DWD tells employers to report any claim of injury within 7 days |
| Insurer or self-insured employer to the division | 14 days | Form WKC-12, the first report of injury, on or before the 14th day after the accident. If the employer reported late, the carrier files within 7 days of learning of the injury (DWD 80.02(2)(a)) |
| Insurer or self-insured employer, supplementary report | 30 days | Form WKC-13 on or before the 30th day following the injury (DWD 80.02(2)(b)) |
| Waiting period | 3 calendar days | No wage replacement for the first 3 days. If disability extends beyond 7 calendar days, those 3 days are paid retroactively |
| First indemnity payment | About 14 days | DWD tells injured workers to expect the carrier’s first check generally within 14 days and to call if it takes longer |
| Intentional failure to file a report | Up to $30,000 | A bad faith penalty of up to 200 percent of compensation due, capped at $30,000, plus a 10 percent penalty where delay in reporting caused an untimely payment |
One structural point saves a lot of confusion. In the ordinary case the employer never files with the state. You report to your carrier, and your carrier files the WKC-12 and the WKC-13. The single exception is a death, which goes to the division and the carrier inside 24 hours.
The seven-day rule has a trigger worth reading twice. The rule keys off disability past the third day or the carrier picking up medical costs, but the department’s instruction to employers is simpler and safer: report any claim of injury to the carrier within seven days, including medical-only claims. Reporting something that turns out to be minor costs you nothing. Sitting on something that turns out to be serious costs you the bad faith exposure above.
What Going Uninsured Costs
The floor is twice the premium you should have paid, or $750, whichever is greater. That assessment under section 102.82(2) is mandatory and non-negotiable, and 2025 Wisconsin Act 145 raised it for repeat offenders effective April 1, 2026. The department publishes the new schedule in its plain language summary of the 2026 amendments.
| Exposure | Amount or consequence | Source |
|---|---|---|
| Assessment, first or second violation | The greater of twice the insurance premium or $750 | 102.82(2), as amended by 2025 Act 145 |
| Assessment, third violation | The greater of three times the premium or $3,000 | 102.82(2), as amended by 2025 Act 145 |
| Assessment, fourth and later violations | The greater of four times the premium or $4,000 | 102.82(2), as amended by 2025 Act 145 |
| Short lapse alternative | $100 per day where the employer was uninsured 7 consecutive days or less, had never been uninsured before, and no injury occurred during the lapse | 102.82(2)(ag) |
| Court forfeitures | First violation the greater of $1,000 or the premium amount, rising to the greater of $4,000 or four times the premium at the fourth violation | 102.85(1), as amended by 2025 Act 145 |
| Surcharge | An uninsured employer surcharge equal to 75 percent of any fine or forfeiture imposed | 102.85(4) |
| Closure order | The department may order the employer to cease operations until it complies. A hearing is available if requested within 10 days of the notice | 102.28(4) |
| Criminal exposure | Violating a cease operations order is a Class I felony. Act 145 also made false or fraudulent insurance applications, including misclassifying employees to lower premium, criminally punishable insurance fraud | 102.85(3), 102.125 and 943.395(1)(e) |
| Personal liability | If the uninsured employer is a corporation, the officers and directors are individually, jointly and severally liable for any part of a judgment returned unsatisfied, and the employer loses the property exemptions from seizure and sale | 102.28(5) |
| Repayment after an injury | Reimbursement to the Uninsured Employers Fund of all benefits paid plus claim administration expenses, due within 30 days, with interest at 1 percent per month | 102.82(1) |
| Collection | Warrants, levies, garnishment and execution against property, with the department’s claim given preference over general creditors | 102.83 and DWD Uninsured Employers Fund guidance |
| Refusing to rehire | Lost wages during the refusal, up to one year’s wages, where suitable employment within the employee’s limitations was available and refused without reasonable cause | 102.35(3) |
Read the personal liability row twice if you run a corporation. Section 102.28(5) reaches officers and directors directly once a judgment against the company comes back unsatisfied, and it strips the exemptions that normally protect property from execution. An uninsured claim is not a problem that stops at the company.
The other number to sit with is the reimbursement. The fund pays your injured employee in full, then bills you for the benefits and the cost of administering the claim. A serious back injury with years of wage loss produces a bill scaled to that whole stream, not to the premium you avoided.
What to Do When Someone Gets Hurt
Work the same sequence every time, in this order. The first three steps happen the same day. Deciding whether the claim is legitimate is not on the list, because that call belongs to the insurer.
Most of this is documentation discipline rather than legal judgment. FirstHR keeps injury forms, acknowledgments and policy documents attached to the employee record, so the copy you handed someone in March is still findable in November without anyone reconstructing it from memory.
Safety work sits next door and reduces how often you run the sequence at all. Wisconsin has no state OSHA plan covering private employers, so the federal baseline applies, and our guide to OSHA requirements for employers covers it. The premium side is in our walkthrough of the workers’ compensation audit.
Frequently Asked Questions
When does a Wisconsin business have to buy workers’ compensation insurance?
On the day it employs a third person, or by the 10th day of the first month of the quarter after it paid $500 or more in gross combined wages. Both triggers come from section 102.04(1)(b). Farms cross at six employees on the same day for any 20 days in a calendar year and have 10 days after that to get insured. Full-time and part-time employees count the same way, and so do minors, family members and corporate officers.
Can I leave myself out of the policy as the owner?
It depends on the entity. Sole proprietors, partners and LLC members are not employees, so they are outside coverage unless the policy is endorsed to include them. Corporate officers are employees, and a closely held corporation of no more than 10 stockholders may exclude up to two named officers by endorsement. A corporation with no more than two officers and no other employees may file a Corporate Officer Option Notice and stay outside the Act. Excluded officers still count toward the thresholds.
Where does a Wisconsin employer buy a policy?
From a private carrier licensed in Wisconsin, usually through an agent. There is no state fund, and the department counts about 300 licensed carriers. The policy has to name Wisconsin in section 3-A and be filed by the carrier with the Wisconsin Compensation Rating Bureau. If the open market declines you, your agent applies to the Worker’s Compensation Insurance Pool that the bureau administers. Self-insurance requires department approval, five years of audited financials and at least $500,000 in security.
Does Wisconsin require a workers’ compensation poster?
No. Chapter 102 has no posting mandate and the workers’ compensation notice is not part of the state’s mandatory workplace poster packet. The department still publishes one, form WKC-19606-P, with blanks for your carrier’s name, address and phone number. Posting matters for a different reason: under section 102.12, if no representative has been designated by posted notice, an injury report to any superior counts as notice to you.
How fast does a work injury have to be reported?
The employee should report immediately, and actual notice has to reach the employer or a designated representative within 30 days, though missing notice does not bar a claim unless the employer was misled. You report to your carrier within seven days, and a death goes to the division and the carrier within 24 hours. The carrier files the WKC-12 first report with the division by the 14th day and the WKC-13 supplementary report by the 30th.
What happens if I have no coverage and someone gets hurt?
The Uninsured Employers Fund pays your employee, then bills you for every benefit plus the cost of administering the claim, due in 30 days with 1 percent monthly interest. On top of that comes an assessment of twice the premium you avoided or $750 minimum, more for repeat violations since April 2026. The department can order your business closed until you comply, and officers and directors are personally liable for any unsatisfied part of a judgment.
Are independent contractors and household workers covered?
A worker is your employee unless the person meets and maintains all nine conditions in section 102.07(8), and the department says plainly that an agreement between the parties does not make someone a contractor. Domestic servants are genuinely excluded from the definition of employee, as is anyone whose work is not in the trade, business, profession or occupation of the employer, and you may elect to cover either group anyway.
Wisconsin amends chapter 102 more often than most employers check it. Our Wisconsin hiring guide covers what has to be in place before the first employee starts, and coverage belongs on that list rather than on the one you get to later.
