Is Workers’ Comp Required in Wisconsin?
Yes, workers compensation insurance is required in Wisconsin for employers with 3 or more full-time or part-time employees, or for employers with 1 or more employees to whom they have paid combined gross wages of 500 or more in any calendar quarter for work performed in Wisconsin
Wisconsin Workers’ Comp Requirements at a Glance
Here are the exact Wisconsin workers compensation requirements every employer should know:
| Employees that trigger the mandate | 3 |
| Which workers count | All full-time and part-time employees count toward the threshold; once an employer has 3 or more workers, coverage must begin the day the third person is hired; employers with fewer than 3 employees must still obtain coverage by the 10th day of the first month of the next calendar quarter if they paid 500 or more in combined gross wages in any quarter; farm employers have a separate threshold requiring coverage when they employ 6 or more workers on any 20 days during a calendar year |
| Who is exempt | Sole proprietors, partners, and members of LLCs are exempt from coverage but may elect to be covered by endorsing their policy; domestic servants are exempt; persons whose employment is not in the trade, business, profession, or occupation of the employer (casual employees) are exempt; some farm employees are exempt; volunteers including volunteers of nonprofit organizations receiving not more than 10 dollars per week are exempt; religious sect members who qualify and are certified for an exemption; employees of Native American tribal enterprises unless the tribe elects to waive sovereign immunity; real estate brokers, agents, and salespersons meeting the requirements of s. 452.38 Wis. Stats.; employees covered under federal statutes such as railroad workers under FELA, longshore workers, and federal employees are exempt from the state act |
| Owners & officers | Sole proprietors, partners, and LLC members are automatically excluded from coverage but may voluntarily elect coverage by endorsing their workers compensation policy; corporate officers are generally covered as employees under the Act, but in a closely held corporation with not more than 10 stockholders, up to 2 officers may exclude themselves from coverage by endorsement on the policy naming each excluded officer; if a closely held corporation has no more than 2 corporate officers and no other employees, a workers compensation policy is not required if both officers elect not to be subject to the Act |
| Penalty for going without | The penalty for operating without required coverage is twice the amount of the premium that should have been paid during the uninsured period, or 750, whichever is greater; for a first-time lapse of 7 consecutive days or less with no injury during the lapse, the penalty is 100 per uninsured day up to 7 days; uninsured employers are also liable to reimburse the Uninsured Employers Fund for all benefit costs paid on valid claims filed by injured employees; the state may pursue collection through warrants and property garnishment if the employer fails to repay the fund |
| Monopolistic state? | No — buy from private carriers |
| State fund | Wisconsin does not have a state fund; the Wisconsin Compensation Rating Bureau (WCRB) administers an assigned-risk pool as the insurer of last resort for employers unable to obtain coverage in the voluntary private market |
How to Get Workers’ Comp Coverage in Wisconsin
Wisconsin employers obtain coverage by purchasing a policy from a private insurance carrier licensed in the state; employers who cannot find coverage in the voluntary market may apply through the Wisconsin Compensation Rating Bureau (WCRB) assigned-risk pool, which assigns a servicing carrier to issue and manage the policy; self-insurance is also available for qualifying employers who demonstrate financial ability and are approved by the Department of Workforce Development
Private market: YES
What Workers’ Comp Covers in Wisconsin
Workers’ compensation is a no-fault system: an injured employee gets benefits without having to prove the employer did anything wrong, and in exchange gives up the right to sue for most workplace injuries. A typical Wisconsin policy pays for medical treatment tied to a work injury, part of the wages lost while the worker recovers, longer-term disability benefits if the injury is permanent, and death benefits to a family.
It also includes employers-liability coverage, which protects the business if an injury still leads to a lawsuit. That trade-off is the practical heart of the Wisconsin workers compensation requirements: the coverage exists to keep one bad injury from sinking both the worker and the business.
Employees vs. Independent Contractors in Wisconsin
The most common way owners get the Wisconsin workers compensation requirements wrong is by assuming a worker is an “independent contractor” who does not count. State agencies look at how the work is actually controlled, not the label on a 1099. If Wisconsin decides a contractor was really an employee, the business can owe back premiums and penalties as if coverage should have been in place all along.
When you are close to the employee threshold, confirm each worker’s status with your state board before you decide you are exempt.
Other Wisconsin workers’-comp rules: Wisconsin uses the term Worker’s Compensation (singular Worker’s) in its statutes rather than the more common Workers’ Compensation; the Uninsured Employers Fund (UEF) pays benefits on valid claims from employees of illegally uninsured employers and then seeks reimbursement from the employer; farm employers have a separate threshold of 6 or more employees on 20 or more days in a calendar year; effective January 1 2026,
workers compensation adjudicatory functions including hearings transferred to the Worker’s Compensation Division in the Department of Workforce Development; all insurers licensed to write workers compensation in Wisconsin must participate in funding the WCRB assigned-risk pool
Understanding Wisconsin Workers Compensation Requirements
