Hiring in Wisconsin: Employer Registration, New Hire Reporting and Labor Laws

Your first employee adds state obligations that a single-owner business never had to handle: withholding, unemployment insurance, new hire reporting and wage rules. Wisconsin does not issue one general business license that covers all of this. Instead, you register with two state agencies, report each new hire within a fixed window and follow labor rules on pay, hours and minors. This guide covers the order to do things in and the figures to plan around.

This guide is informational only. It is not legal, tax or employment advice. Wage, tax and labor rules change, and any figure marked to confirm should be checked with the named agency before you rely on it. Consult a qualified attorney or CPA before you make decisions about pay, worker classification or payroll.

Start with the entity and a one-stop registration

If you hire through an LLC or corporation, form the entity first. Wisconsin business entities are filed with the Department of Financial Institutions (DFI), not the Secretary of State. An LLC files Articles of Organization for a $130 filing fee, and a stock corporation files Articles of Incorporation for a $100 filing fee. Search the name in the DFI business search before you file.

Wisconsin has no general state or county business license, and most cities do not issue one either. Licenses attach to specific activities. Regulated occupations are licensed by the Department of Safety and Professional Services (DSPS). Certain food and agricultural activities involve the Department of Agriculture, Trade and Consumer Protection (DATCP) or a local health department acting as its agent. Alcohol and some other listed activities go through the municipal clerk. Your city or county may add zoning or licensing requirements, so ask the clerk before you advertise a job.

The Wisconsin One Stop Business Portal at onestop.wi.gov registers a new business with DFI, the Department of Revenue (DOR) and the Department of Workforce Development (DWD) in one pass. It is the fastest way to cover the next two steps.

Register for withholding with DOR

Before your first payroll, get a federal Employer Identification Number (EIN) from the IRS, then open a Wisconsin withholding account with DOR. Apply through DOR's Business Tax Registration system at https://tap.revenue.wi.gov/BTR/ or through One Stop. DOR's new business page is at https://www.revenue.wi.gov/Pages/Businesses/New-Business-home.aspx.

Wisconsin income tax withholding follows the graduated structure of the individual income tax, with rates from 3.50% to 7.65%. For single filers, the 3.50% rate applies up to $14,680, 4.4% applies from $14,680 to $50,480, 5.3% applies from $50,480 to $323,290 and 7.65% applies above $323,290. Each employee completes a Wisconsin withholding exemption form (Form WT-4) on hire. Confirm the current form version and your deposit schedule with DOR, since the deposit frequency depends on how much you withhold.

Register for unemployment insurance with DWD

Wisconsin employers open an unemployment insurance (UI) account with DWD. UI tax applies to the first $14,000 of each employee's wages in a calendar year. New employers pay a fixed rate for their first three calendar years. For 2025, that fixed rate ranged from 2.90% to 3.25%, depending on payroll and industry. Confirm the 2026 rate with DWD before you budget, because the rate can change each year. Once your account is established, your quarterly UI wage reports are built from the same payroll records you keep for withholding, so set up one accurate system from day one.

Report every new hire within 20 days

Wisconsin requires employers to report each new hire to the state within 20 days of the hire date. This report is separate from your withholding and UI filings. The state uses these reports to enforce child support orders and to check benefit claims. Submit the report through DWD's new hire reporting program at dwd.wisconsin.gov. Missing the 20-day window is a common gap for employers hiring their first few people, so add it to your onboarding checklist and assign one person to own it.

Overtime and final paycheck rules

Wisconsin wage and hour rules are administered by DWD and sit alongside the federal Fair Labor Standards Act. Employees who are not exempt must receive a time-and-a-half premium for hours beyond the weekly threshold. The exemptions for executive, administrative and professional roles are narrow, and classifying a salaried worker as exempt is a frequent source of wage claims. Confirm the weekly threshold and the exemption tests with DWD, and with an employment attorney if a role is borderline.

Final pay is the next trap. Wisconsin sets rules for when a departing employee must receive final wages and what those wages include. Check the current timing and requirements with DWD before your first separation. Build the process now: know your regular payday, track accrued pay and keep final payroll ready to issue.

Paid sick leave

Wisconsin does not have a general state paid sick leave law. Local sick leave ordinances are preempted, so a city or county cannot require you to provide paid sick leave. Any paid leave you offer is a business decision. Put it in a written handbook or offer letter and apply it consistently, so it does not become a dispute later. If you read about a specific local rule, confirm with DWD whether it applies to your business.

Child labor and work permits

Wisconsin child labor rules apply to minors under 18. Minors aged 14 and 15 need a work permit before they start work. The permit costs $10, and the employer reimburses that cost. Keep a copy of each minor's permit on file, and confirm the issuing process, required forms and permitted hours and occupations with DWD before you put a teen on the schedule. Hiring anyone under 14 raises separate questions, so confirm with DWD before making that offer.

Independent contractors and workers' compensation

Classifying a worker as an independent contractor is not a single test. The tests Wisconsin applies for unemployment insurance differ from the tests that apply to workers' compensation, so a person can be a contractor for one purpose and an employee for another. Document the working relationship and any contract terms, and review how much control you exercise over hours, tools and methods. Confirm your classification with DWD and your workers' compensation insurer, because a wrong call can create back UI tax and premium liability.

Wisconsin requires most employers with employees to carry workers' compensation coverage. Ask your insurer which workers are covered and have the policy in force before your first employee starts work.

New employer checklist

1. Form the LLC or corporation with DFI, or confirm your sole proprietorship or partnership setup.

3. Obtain your federal EIN and Wisconsin withholding account before running payroll.
4. Collect the federal Form W-4 and Wisconsin Form WT-4 from every hire on day one.
5. Report each new hire to the state within 20 days of the hire date.
6. Bind workers' compensation coverage before the first shift.
7. Obtain a $10 work permit for every 14 or 15 year old before the first shift.
8. Confirm the 2026 UI rate, overtime threshold and final pay timing with DWD.
9. Ask your city or county clerk about local licensing and zoning before you advertise.

Hiring is where a small business most often trips over state rules, and most of the cost comes from catching a missed deadline late. Register early, set up payroll correctly on the first run and confirm the items marked above with the agency that owns them. If a worker classification, final pay situation or minor's schedule is unclear, talk to a qualified employment attorney or CPA before you act.
