To file a workers’ compensation claim in Wisconsin, start with notice: tell your employer within 30 days under Wis. Stat. § 102.12. Your employer then reports the injury to its insurer, which files the first report (WKC-12) with DWD when required, and the insurer pays or denies. If it denies, you file a hearing application within the § 102.17(4) limitation period — six years for most traumatic injuries, while an occupational disease has no statute of limitations. Madison-area Mays Law Office represents injured workers statewide.
Steps at a glance:
- Tell your employer. Under Wis. Stat. § 102.12, your employer must actually receive notice within 30 days after the injury, or within 30 days after you knew or ought to have known the nature of your disability and its relation to your work. A late report can be excused if the employer was not misled by the delay.
- Get medical care from a practitioner you choose, within the limits of Wis. Stat. § 102.42(2). Tell the provider how the injury happened at work, and keep your medical and payment records.
- Your employer reports the injury to its insurer, which reports it to DWD if required. If you reported the injury, you do not have to file a claim yourself.
- Watch for the first check. If the claim is payable and you miss more than three days of work, it usually arrives within 14 days of your last day worked.
- Denied and no lawyer? DWD’s Alternative Dispute Resolution (ADR) Unit reviews the claim first and may contact you and the insurer to resolve it without a formal hearing.
- Still disputed? File a Hearing Application (Form WKC-7) with a medical report that supports your claim; DWD will not schedule a hearing until it has one. See what to do after a denial.
- Appeal on time. DWD or LIRC must receive a petition for review within 21 days after DWD mails the administrative law judge’s decision. To take LIRC’s decision to circuit court, the summons and complaint must be filed, and LIRC must receive authenticated copies, within 30 days after LIRC mails its decision.
Getting hurt at work in Wisconsin starts a set of clocks that most people never hear about until one has already run out. Some of those clocks are yours. Others belong to your employer and its insurance company — and knowing what they are required to do, and by when, is often the difference between a claim that gets paid and a claim that quietly stalls.
This guide walks through the process in order: what you have to report and how fast, what your employer and the insurer must file, what happens when a claim is denied, and how Wisconsin actually calculates what a claim is worth. Everything below is verified against the Wisconsin Statutes and the Department of Workforce Development’s own rules, current as of September 2026 — which matters this year, because two 2025 laws changed both the benefit rates and the agency that hears disputed claims.
One framing point before the steps, and it shapes everything that follows. A Wisconsin workers’ compensation claim is not a lawsuit against your boss. Under the exclusive-remedy provision, Wis. Stat. § 102.03(2), workers’ compensation is the sole avenue of recovery against your employer for a work injury. It is an administrative claim for statutory benefits — wage replacement and medical care — handled through a state agency rather than a courtroom.
How to File a Workers’ Compensation Claim in Wisconsin: Step One Is Notice to Your Employer
Everything begins with telling your employer. Wis. Stat. § 102.12 sets the rule, and it is written as a bar on the claim itself:
“No claim for compensation may be maintained unless, within 30 days after the occurrence of the injury or within 30 days after the employee knew or ought to have known the nature of his or her disability and its relation to the employment, actual notice was received by the employer or by an officer, manager or designated representative of an employer.”
Three details in that sentence do real work:
- The statute gives two alternative measuring points. The 30 days run from the occurrence of the injury, or from when you knew or ought to have known the nature of your disability and its relation to your employment. That second measure matters most for conditions that build over time — a repetitive-motion injury, hearing loss, a chemical exposure — where there may be no single day an “accident” happened.
- Notice must actually reach the right person. The statute requires actual notice to the employer or to an officer, manager, or designated representative — so whether a given supervisor counts depends on whether that person is authorized or designated to receive it. Mentioning the injury to a coworker who holds none of those roles does not satisfy the statute. Report it in writing, through whatever procedure your employer has designated for work injuries, and keep a copy.
- It is 30 days, not two years. This is the single most common mistake in online summaries of Wisconsin law.
Missing 30 Days Is Not Automatically Fatal
The same statute contains a saving provision: “Absence of notice does not bar recovery if it is found that the employer was not misled by that absence.” In practice, that turns a missed deadline into an argument — you are now relying on a finding that your employer was not prejudiced by the delay, rather than on a clean, documented report. That is a much weaker position to be in, and it is entirely avoidable.
The Two-Year Outer Limit
Section 102.12 contains a second, longer bar with its own conditions. Where no compensation has been paid, the statute provides that if “no application is filed with the department within 2 years after the date of the injury or death or the date the employee or his or her dependent knew or ought to have known the nature of the disability and its relation to the employment, the right to compensation for the injury or death is barred” — with an exception preserved in the same sentence: the right is not barred “if the employer knew or should have known, within the 2-year period, that the employee had sustained the injury.”
So the two-year rule is a conditional bar, not an unconditional one. It bites only where no qualifying compensation was paid, no application was filed inside the two years, and the employer neither knew nor should have known of the injury in that period — note that an employer’s actual ignorance is not enough if it should have known. That is a poor set of facts to be arguing about, which is the practical point.
Read together, § 102.12 says: report it now, in writing, to a manager. Do not plan on the saving clauses. And note that this notice section is separate from the deadline for filing a claim, which is the subject of the next section.
The Second Clock: Six Years for Most Traumatic Injuries, No Statute of Limitations for an Occupational Disease
Notice is one deadline. The statute of limitations for filing a formal claim is a completely separate one, and confusing the two is a common and expensive error.
Under Wis. Stat. § 102.17(4), how long you have depends on what kind of injury you have:
| Injury type | What it means | Statute of limitations |
|---|---|---|
| Traumatic injury | A sudden, discrete event — a fall from a ladder, a crush injury, a machine accident | 6 years in most cases |
| Occupational disease | A condition that develops gradually from prolonged exposure — repetitive-motion damage, cumulative hearing loss, chemical exposure | No statute of limitations |
The six-year period runs from the date of injury or the date compensation was last paid — not counting medical treatment or burial expense — whichever is later. An occupational disease has no statute of limitations.
The “you have 12 years” answer you will find all over the internet is wrong for most injuries. An occupational disease has no statute of limitations. If you fell off a scaffold, the limit is usually six years, unless the injury is one of the serious ones listed below.
The Injuries With No § 102.17(4) Limitation Period
Wisconsin exempts a short list of catastrophic injuries from the § 102.17(4) limitation period. Under § 102.17(4)(b), there is no statute of limitations for a traumatic injury causing the loss or total impairment of a hand or any part of the arm above it, or of a foot or any part of the leg above it; any loss of vision; any permanent brain injury; or a traumatic injury causing the need for an artificial spinal disc, a total or partial knee or hip replacement, a shoulder replacement, or a reverse shoulder replacement (2025 Wisconsin Act 145 added the shoulder replacements).
Note what this exemption does and does not do. It removes the § 102.17(4) filing clock. It does not switch off the separate notice provisions of § 102.12 discussed above — those still apply on their own terms.
2025 Wisconsin Act 145 expanded that list. Effective April 1, 2026, a shoulder replacement or reverse shoulder replacement was added to the injuries that carry no statute of limitations. If shoulder-replacement surgery is part of your work-injury history, that is worth raising with a lawyer — how the amendment applies to any particular claim depends on the facts and dates of that claim.
Act 145 also settled how filing pauses the clock. Filing a hearing application tolls the limitation period until the case reaches final disposition — but the tolling ends when a dismissal order is entered, even a dismissal without prejudice. The paused time is not added back onto the end of your period.
What Happens Next: The Employer’s Report, the Insurer’s Clock, and Your First Check
Once you report the injury, obligations shift to your employer and its insurance carrier under Wis. Stat. § 102.38 and Wis. Admin. Code ch. DWD 80. These are not courtesies. They are filing duties with dates attached.
- The employer’s report to its insurer. Under DWD 80.02(1), an insured employer must notify its insurance carrier within 7 days after the accident (or the beginning of a disability from occupational disease) when disability continues beyond the third day after you leave work, or when the carrier is primarily liable for unpaid medical treatment. A work-related death must be reported to DWD and the carrier within one day.
- The first report to DWD. When disability continues beyond the third day, DWD 80.02(2)(a) requires the insurance carrier (or a self-insured employer) to file the first report of injury, WKC-12 (Employer’s First Report of Injury or Disease), with DWD on or before the 14th day after the accident or the beginning of a disability from occupational disease — or, if the employer did not notify the carrier until after the 14th day, within 7 days after the carrier receives notice of the injury from any source.
- The supplementary reports. The carrier files a WKC-13 on or before the 30th day after the injury to report payment status, and again whenever payments change. A WKC-13-A1 wage supplement (WKC-13-A for injuries before April 10, 2022) is required within 30 days when the benefit rate falls below the maximum.
- A denial has to be in writing. Under DWD 80.02(2)(g), when an insurer stops or denies payment it must notify you in writing within 7 days, explain why, and tell you how to get payments reinstated. A carrier that simply goes silent is not following the rule.
Current DWD forms are published on the department’s official form index at dwd.wisconsin.gov/dwd/forms/wkc/.
The Three-Day Waiting Period
Wisconsin does not pay wage benefits from day one. Under Wis. Stat. § 102.43(1), there is a three-day waiting period after you leave work because of the injury, and wage compensation becomes due once that period has run. One wrinkle in the counting: a Sunday counts toward the three days only if you regularly worked Sundays. And if your disability continues beyond the 7th calendar day, or the injury causes a permanent disability, those waiting-period days are paid back to you retroactively.
So a short absence may produce medical coverage and no wage check, while a longer one eventually produces both. If you were off work for more than a week and were never paid for the first three days, that is worth asking about.
Denied or Delayed: Filing a Hearing Application and Who Hears the Case in 2026
If the insurer denies your claim, stops paying, or simply lets it sit, the burden to move it shifts to you. You start the dispute by filing a WKC-7 (Hearing Application), which puts the claim into the adjudicatory system and tolls the statute of limitations.
Here is what changed, and what most online answers still get wrong. For years, Wisconsin split the work: DWD administered comp claims while the Department of Administration’s Division of Hearings and Appeals ran the hearings. 2025 Wisconsin Act 33 transferred the adjudicatory functions and the administrative law judges back to the Department of Workforce Development, effective January 1, 2026. As of August 2026, Wisconsin workers’ compensation disputes are administered and heard inside DWD. Guides that still send injured workers to the Division of Hearings and Appeals are describing the old structure.
From there, the path is defined:
- Informal resolution. DWD may try to help the parties — particularly unrepresented ones — resolve the dispute before a formal hearing is docketed.
- Prehearing and formal hearing before a DWD administrative law judge. Medical evidence is handled on paper far more often than in person: a disputed medical opinion is typically placed into evidence through a certified WKC-16-B (Practitioner’s Report in Lieu of Testimony) rather than live doctor testimony. Whether that report says the right things is frequently the whole case.
- Petition to LIRC within 21 days. After the ALJ rules, Wis. Stat. § 102.18(3) requires that a petition for review by the Labor and Industry Review Commission be received by DWD or the commission within 21 days after DWD mails the decision. The statute is unforgiving: the commission “shall dismiss a petition that is not filed within those 21 days unless the petitioner shows that the petition was filed late for a reason that was beyond” the petitioner’s control.
- Circuit court within 30 days. A LIRC decision may be appealed to circuit court under Wis. Stat. § 102.23: within 30 days after LIRC mails its decision, you file a summons and complaint in circuit court, naming LIRC and the other required parties, and LIRC must receive the clerk-stamped, authenticated papers within those 30 days. From there, a case can go to the Wisconsin Court of Appeals and the Wisconsin Supreme Court.
Most disputes end before a formal hearing. DWD reports that about 80% of hearing requests are settled without one, many by compromise or stipulation. Every compromise must be approved by DWD, and once you agree to one it is legally very difficult to change, so understand which future benefits you would be giving up before you sign.
The Penalties a Stalling Insurer Faces
Wisconsin does attach consequences to bad claim handling, and knowing they exist changes the conversation:
- Inexcusable delay in payment subjects the insurer to a 10% penalty on the delayed amount under § 102.22.
- Bad faith. Under § 102.18(1)(bp), DWD may impose a penalty of the lesser of 200% of the compensation due or $30,000 for each act of bad faith. Whether a particular denial meets Wisconsin’s bad-faith standard is a separate, fact-specific question — the test generally turns on whether the insurer lacked a reasonable basis for denying benefits and knew of, or recklessly disregarded, that lack of a reasonable basis.
- Unreasonable refusal to rehire. If your employer refuses without reasonable cause to take you back after you are medically cleared and suitable work exists, § 102.35(3) makes it liable for the wages you lost during the refusal, “not exceeding one year’s wages.”
- Safety violations cut both ways. An injury caused by the employer’s failure to follow a safety statute or order increases compensation by 15%, capped at $15,000 (§ 102.57). Section 102.58(1) runs the same 15% and $15,000 in reverse against the worker, but only on specific grounds: an injury caused by failing to use safety devices that are provided as required by law, adequately maintained and reasonably enforced by the employer, or by failing to obey a reasonable safety rule that the employer adopted and reasonably enforces and that you had notice of. Separately, under § 102.58(2), if a violation of the employer’s drug or alcohol policy caused the injury, no compensation or death benefits are payable, although medical treatment and related incidental benefits remain payable. Otherwise, benefits are generally paid even if the injury was your fault.
What a Claim Is Worth: Wage Rates, PPD Ratings, and Why the Rating Fight Matters
Wisconsin comp is arithmetic, not argument about how much you suffered. Chapter 102 pays no compensation for pain and suffering. What it pays is wage replacement and medical care, calculated from your average weekly wage (AWW) under § 102.11. That statute does not use a single universal formula — it supplies several methods, and which one applies depends on your circumstances, including how long you had been working, the nature of the job, and what comparable employees earn. Getting the AWW right is worth attention, because every wage benefit below is a fraction of it.
Wage replacement while you heal:
- Temporary Total Disability (TTD) — two-thirds of your AWW while you are wholly unable to work during the healing period (§ 102.43(1)), subject to the maximum in effect for your injury year. Those maximums are published on the DWD rate sheet, WKC-9572-P. As of August 2026, that sheet lists a maximum weekly TTD rate of $1,375 for injuries occurring in 2026, tied to 110% of the state average weekly wage. Rates are injury-date specific: the sheet is updated annually, and legislation can move a rate on another date entirely — Act 145 moved the maximum PPD rate on April 1, 2026. Check the current chart against your own date of injury before relying on any figure.
- Temporary Partial Disability (TPD) — two-thirds of the difference between your old wage and your reduced earnings if you return to light duty at less pay (§ 102.43(2)).
- Permanent Total Disability (PTD) — lifetime wage replacement where an injury leaves you permanently unable to perform steady work (§ 102.44).
Permanent Partial Disability — where cases are won and lost. Once you reach maximum medical improvement, a doctor assigns a permanent impairment rating. PPD is also paid at two-thirds of AWW, but under a far lower cap that is fixed by your injury date. The maximum weekly PPD rate is $446 for injuries from January 1, 2025 through March 31, 2026; 2025 Wisconsin Act 145 raised it to $454 for injuries from April 1, 2026 through December 31, 2026 and $462 for injuries on or after January 1, 2027. Benefit dollars change with the injury year — always check the current DWD WKC-9572-P chart against your own date of injury.
How that rating converts into money depends on the body part:
- Scheduled losses (arms, legs, hands, feet, eyes, ears) carry a statutory number of weeks per body part under §§ 102.52–102.555. The impairment percentage is multiplied by those weeks.
- Unscheduled losses (spine, torso, head, internal organs) are measured against the 1,000-week “body as a whole” base in § 102.44(3). A 10% back rating equals 100 weeks of PPD.
That is why a rating dispute is not a technicality. On an unscheduled back injury, the difference between a 5% and a 10% rating is 50 weeks of benefits.
Two more things worth knowing. Wisconsin comp wage benefits are not taxable — they are excluded from income under federal law and are not reported as Wisconsin taxable income. And under § 102.42 there is no time limit and no dollar cap on reasonable and necessary medical treatment for the injury. Unlike states where the employer picks the doctor, Wisconsin gives you the choice of treating practitioner, plus a second choice on notice to the employer or insurer (§ 102.42(2)).
If you cannot go back to your old job. When your practitioner or employer says you cannot return to your former job, DWD’s guide for injured workers says you may ask the insurer for help from public or private vocational rehabilitation services, such as the state Division of Vocational Rehabilitation (DVR).
Five Things Online Answers Get Wrong About Wisconsin Workers’ Comp
| The common answer | What Wisconsin law actually says |
|---|---|
| “You have 12 years to file.” | An occupational disease has no statute of limitations. Most traumatic injuries are 6 years (§ 102.17(4)). |
| “You have two years to report the injury.” | Section 102.12 calls for actual notice within 30 days — though late notice does not automatically bar recovery if the employer was not misled. The separate two-year rule in the same section bars the claim only where no compensation was paid, no application was filed, and the employer neither knew nor should have known of the injury within that period. |
| “You sue your employer.” | Comp is the exclusive remedy against the employer — an administrative claim, not a civil suit (§ 102.03(2)). A claim against a negligent outside party is separately allowed under § 102.29. |
| “You can recover pain and suffering.” | Chapter 102 pays wage loss and medical care only. There is no pain-and-suffering component. |
| “Your employer picks your doctor.” | In Wisconsin, you choose your treating practitioner, and you have a right to a second choice on notice (§ 102.42(2)). |
Frequently Asked Questions About Filing a Workers’ Comp Claim in Wisconsin
How do I file a workers’ comp claim in Wisconsin?
You start by reporting the injury to your employer, not by filing a form with the state. Your employer reports it to its insurer, which reports it to DWD’s Worker’s Compensation Division when required, and the insurer pays or denies the claim. If your employer does not report the injury, or you believe you have not received all the benefits you are owed, you can file a Hearing Application (Form WKC-7) with DWD, supported by a practitioner’s written report on the disputed medical issues.
Do I have to file anything if my employer reported the injury?
Usually not. DWD’s guide for injured workers says you do not have to file a claim yourself if you reported the injury. Your part is to get treatment, send any medical bills or receipts to your employer or its insurer, keep your medical and payment records, and tell the insurer if your income changes or you start working again. If your employer was illegally uninsured and you were hurt on or after July 1, 1996, you file a claim with the state’s Uninsured Employers Fund instead.
How long do I have to report a work injury in Wisconsin?
Under Wis. Stat. § 102.12, your employer must actually receive notice within 30 days after the injury, or within 30 days after you knew or ought to have known the nature of your disability and its relation to your work. Notice to an officer, manager or designated representative counts, and if none is designated on workplace posters, notice to any superior is enough. A late report can be excused if your employer was not misled by the delay, but report right away, in writing, and keep a copy.
What is the statute of limitations for workers’ comp in Wisconsin?
Wis. Stat. § 102.17(4) allows six years to file a hearing application for most traumatic injuries on or after March 2, 2016, from the injury or the last payment other than for medical or burial expenses, whichever is later. An occupational disease has no statute of limitations, nor do the serious traumatic injuries listed in § 102.17(4)(b). Section 102.12 bars a claim after two years if nothing beyond medical or burial expenses was paid, no application was filed, and your employer neither knew nor should have known of the injury.
When will I get my first workers’ comp check?
If you miss more than three days of work, DWD’s guide says the insurer usually makes the first payment within 14 days of your last day worked. If the insurer is still investigating, it must notify you within 14 days after it receives notice of the injury. If a check is late, ask your employer or its insurer why. Cashing compensation checks does not waive any of your legal rights.
What happens if my workers’ comp claim is denied?
The insurer must tell you within 7 days of its decision and advise you of your right to a hearing. If you do not have a lawyer, DWD’s Alternative Dispute Resolution (ADR) Unit reviews the claim first, checks that your medical information supports it, and may contact you and the insurer to resolve the dispute without a formal hearing. If it cannot be resolved, you can ask for a hearing before a DWD administrative law judge by filing a Hearing Application (Form WKC-7) with medical support for the claim.
How do I file a Hearing Application (Form WKC-7)?
DWD’s instructions say to fax it to the Worker’s Compensation Division, or to mail it or file it in person in Madison, and to keep the original. Submit medical documentation for each injury date, usually your doctor’s report on Form WKC-16-B; DWD will not schedule a hearing until it receives that support. Ready cases are scheduled first-in, first-out, and the wait can be several months. DWD notifies you by mail at least 10 days ahead and schedules hearings only through written letter.
Do I need a lawyer to file a workers’ comp claim in Wisconsin?
No, it is not required. DWD’s hearing instructions say you may present your own case, but the administrative law judge is not your attorney and cannot investigate or arrange for witnesses. If you hire a lawyer, the fee generally cannot exceed 20% of the amount recovered (10%, up to $250, when liability is admitted, nothing is disputed and no hearing or appeal is needed) and must be approved by DWD; DWD’s instructions add that if nothing is recovered you owe no fee for the attorney’s time, though actual costs such as medical reports may be charged.

Injured on the Job in Wisconsin? Talk to Mays Law Office.
Plenty of Wisconsin claims move without a fight. The employer files the report, the insurer accepts the claim, the checks arrive, and the medical bills get paid. Whether you should talk to a lawyer depends on what the benefits, the medical issues, and the deadlines look like in your case — and it becomes urgent when something breaks: a denial letter, payments that stop without explanation, a return-to-work offer that ignores your restrictions, or an impairment rating that seems far too low for what the surgery actually did.
Those are the points where the deadlines above start to matter — the 21 days to petition LIRC, the six-year statute of limitations for most traumatic injuries, the WKC-16-B that has to say the right things before a hearing. Attorney Lisa Pierobon Mays concentrates her practice on Wisconsin workers’ compensation for the injured worker and brings 25+ years of experience to those fights. Worth knowing as you weigh whether to call: attorney fees in Wisconsin workers’ compensation cases are not open-ended — they are regulated by statute under Wis. Stat. § 102.26.
We cannot promise you a benefit amount or an outcome — nobody honestly can, because the numbers turn on your wage, your rating, and your healing timeline. What we can do is read the file, tell you whether the insurer is following the rules, and handle the hearing process if it isn’t.
