When coverage is required
Wisconsin generally requires coverage if you usually have three or more employees. You also need it if you have at least one employee and pay $500 or more in total wages in a calendar quarter for work in Wisconsin. Under the wage test, coverage must start by the tenth day of the month after that quarter. Watch both tests. Do not wait for your third hire.
Owners, contractors, and exceptions
Farm work and some other kinds of work have their own rules. The Department of Workforce Development lists exceptions for household work, some volunteers, certain religious exemptions, and other narrow cases. Review owners and contractors separately, and tell your insurer about work in other states. If you send workers into Wisconsin, confirm your policy meets Wisconsin's rules. Do not rely only on your home-state policy.
If an employee is injured
Workers should report an injury or a possible job-related illness right away. Complete the first report, using form WKC-12 when needed, and tell your insurer. The Department says to report a claim to your insurer within seven days. Send wage, medical, and time-off details as you get them. Your insurer's later reports and the worker's claim rights need their own attention.
Operating without coverage
If your coverage lapses illegally in Wisconsin, the penalty is twice the premium you did not pay, or $750, whichever is more. For a first lapse of seven days or less with no injury, the penalty may be $100 per uninsured day instead. The state can order your business to stop operating until you get coverage. If the Uninsured Employers Fund pays a valid claim, you must pay back all of its costs.
How to arrange coverage
Buy a policy from an insurer licensed in Wisconsin, look at the state's insurance pool if needed, or apply to self-insure. Ask your agent to confirm the start date based on your staff or quarterly wages. Keep payroll records by quarter and work location, and review them when you grow or hire seasonal help, so coverage is in place before it is required.
Benefits and return-to-work planning
A work injury can lead to medical care, time off work, a lasting disability, or benefits for family members if a worker dies. Who qualifies, waiting periods, how wages are figured, and benefit limits all depend on state law and the facts of the claim. Ask your insurer which benefits it is looking at and what records it needs. Go by the doctor's work limits, not your own guess about what the worker can do. If you can offer lighter work, describe the duties and hours clearly and plan it with the doctor and your insurer.
Preparing an accurate cost estimate
Gather payroll by job and location, a description of each type of work, details on working owners, subcontractor records, and your past claims. Ask the insurer to confirm your job classes, how the rate is figured, any experience modifier, the minimum premium, fees, and audit terms. This site's calculator uses a base rate that you enter. It does not give a state-approved rate or a real quote. Compare offers using the same numbers, and track staff and work changes during the year so the final audit is easier.
