On March 30, 2026, Governor Tony Evers signed 2025 Wisconsin Act 145 into law, introducing meaningful updates to the state’s workers’ compensation framework.
At a glance, the changes span benefit increases, procedural adjustments, fraud enforcement, and expanded protections for public safety workers. But the real impact is less about what changed and more about how these changes shift employer risk, claim dynamics, and cost exposure moving forward.
Where we’re seeing the biggest impact.
Raising claim costs are being codified
The scheduled increases to permanent partial disability (PPD) benefits formalize a trend employers have already been feeling: claims are getting more expensive.
This is not just a rate issue. It is a severity issue.
Higher benefit caps increase the financial impact of each claim, particularly for:
- Longer-tail injuries
- Claims involving permanent impairment
- Situations where return-to-work timelines are extended
What this means: Employers should expect increased total cost of risk, even if claim frequency remains stable.
Fraud enforcement signals a more active regulatory environment
Act 145 strengthens fraud reporting requirements and enables deeper coordination between insurers, the Department of Workforce Development (DWD), and prosecutors.
This is not just about catching bad actors. It reflects a broader shift toward data-sharing and enforcement across the system.
What this means:
- Misclassification (intentional or not) is under greater scrutiny
- Documentation and classification practices matter more than ever
- Employers may be pulled into investigations even when they are not the primary focus
Settlement flexibility comes with new oversight
Allowing lump-sum settlements to be paid directly to employees simplifies administration. The Act also reorganizes and clarifies the DWD’s existing authority to review, modify, or set aside compromise agreements within one year.
What this means:
- Settlements are not always the final chapter
- Structuring agreements correctly upfront is more critical
- Employers need to understand downstream exposure, not just immediate resolution
Claims handling and procedure are getting tighter
Clarified dismissal standards and filing timelines aim to streamline the system, but they also raise the bar for process discipline.
What this means:
- Poor documentation or missed deadlines can now carry more consequence
- Claims strategy needs to be proactive, not reactive
- Consistency in how claims are handled becomes a defensibility issue
Medical evidence is expanding, and so is risk
The inclusion of physician assistants, APRNs, psychologists, and audiologists as accepted medical sources increases accessibility, but it also broadens the range of opinions that can influence a claim.
What this means:
- More variability in medical opinions
- Greater importance on coordinating medical management
- Increased potential for conflicting reports
Statue of limitations changes extend long-term exposure
The Act reinforces the use of multiple medical professionals in workers’ compensation claims and expands accepted sources to include audiologists. While most of these provider types were already recognized, this update reflects a continued broadening of who can contribute medical evidence in a claim.
What this means:
- Certain claims may remain open risk indefinitely
- Recordkeeping and documentation become long-term assets
- Employers need to think beyond traditional claim lifecycle assumptions
PTSD coverage expansion changes the conversation
Expanded eligibility for PTSD now more clearly applies to specific public safety roles, including firefighters, emergency medical responders, and emergency medical services (EMS) practitioners, in addition to already covered law enforcement.
Mental-only claims, when tied to PTSD, no longer require a physical injury.
What this means:
- Increased claim potential in public sector and adjacent roles
- Greater need for mental health awareness and early intervention
- Clear distinction between covered PTSD and non-covered stress-related conditions becomes critical
Bad-faith penalties raise the stakes
With penalties up to $30,000 or 200% of benefits due, Act 145 reinforces expectations around good-faith claims handling.
These penalties can apply to employers, insurers, or both—and cannot be shifted between parties.
What this means:
- Claims handling decisions carry more financial and reputational risk
- Alignment between employer and carrier is essential
- Documentation and communication are no longer just best practices—they are protections
Yes/And: Our Take
WI Act 145 signals a shift toward high claim costs, increased scrutiny, and greater complexity across workers’ compensation.
For employers, the bigger consideration is how these changes may affect claim exposure, documentation practices, and overall readiness when a claim occurs. Changes like these are a reminder that workers’ compensation is not static, and staying ahead requires more than just keeping up with new legislation.
