Hiring employees in Wisconsin: the 2026 compliance checklist for employers and recruiters

As of October 2026, an employer hiring in Wisconsin has to open an unemployment insurance account with the Department of Workforce Development (DWD) once it meets a liability test, register for a withholding tax number with the Department of Revenue, carry workers' compensation once it has three employees or pays $500 in wages in a quarter, collect Wisconsin Form WT-4 as well as the federal W-4, post the required state notices, and report the hire within 20 days. Arrest questions are limited to pending charges, a conviction counts against a candidate only when it substantially relates to the job, lie detector tests are banned, and salary history questions are expressly allowed. Wisconsin is a one-party consent state and has no E-Verify, pay transparency or AI hiring statute.

This page is the Wisconsin hub: one table with every item and its official source, then a short section on each. Where we already have a full guide to an item, the section summarizes it and links there.

The Wisconsin hiring checklist at a glance

What must be in place before the first Wisconsin hire?

Two tax accounts and, usually, workers' compensation. DWD's employer handbook says a commercial employer becomes liable for unemployment insurance if it "paid wages of $1,500 or more in a quarter in any calendar year" or "employed one or more individuals in employment for some part of a day in 20 or more weeks in any calendar year," counting part-time workers, and registers online. DWD lists the 2026 new-employer rate as 3.05 percent, or 3.25 percent with payroll of $500,000 or more, on the first $14,000 of each employee's wages. The Department of Revenue's Withholding Tax Guide says every employer paying wages subject to Wisconsin withholding "must register for a Wisconsin withholding tax number."

Workers' compensation turns on headcount or payroll. Wis. Stat. § 102.04(1)(b) covers an employer of 3 or more employees from the day it employs the third, and a smaller one that "has paid wages of $500 or more in any calendar quarter," from the 10th day of the following month; DWD's insurance Q&A counts part-time employees. The federal layer (an EIN, Form W-4 and Form I-9 by the third business day) applies on top.

Does a staffing or recruiting agency need a Wisconsin license?

It depends on who pays. Under Wis. Stat. chapter 105, an employment agent paid by job seekers needs a DWD license and a $5,000 surety bond, while "persons whose fees or charges are paid directly by employers shall register annually" for $5. Temporary help services are excluded if they pay the workers' wages and payroll taxes, carry workers' compensation and liability insurance, and do not charge workers for taking a permanent job with the client. Our Wisconsin staffing agency license guide covers fee caps and why an unregistered agent's contract can be void.

What must a Wisconsin job posting include, and can you ask about pay history?

No Wisconsin statute requires a pay range. The 2025 bills that would have, Senate Bill 488 and Assembly Bill 480, failed to pass on March 23, 2026. A remote role open to candidates in Illinois, Minnesota or another range state can still pick up that state's rule; see pay transparency laws by state.

On pay history, Wisconsin goes the other way. Wis. Stat. § 103.36, added in 2017, says "an employer may solicit information regarding the salary history of prospective employees" and bars cities, villages, towns and counties from enacting or enforcing ordinances against it. See salary history ban states for candidates elsewhere.

When can you ask about criminal history or run a credit check?

Arrest record and conviction record are protected bases under the Fair Employment Act, § 111.321, which covers employment agencies as well as employers. Under § 111.335, asking about arrests is discrimination "except a record of a pending charge," and an employer may refuse to hire over a conviction or pending charge only when its circumstances "substantially relate to the circumstances of the particular job," or when a required bond is unavailable. DWD's Equal Rights Division adds that "An employer cannot legally make a rule that no persons with conviction records will be employed"; each job and record is weighed individually. If an outside agency runs the check, follow the FCRA background check process.

We found no Wisconsin statute limiting employment credit checks, and credit history is not on § 111.321's list, so the federal FCRA's steps are the rule; see our credit check laws guide. Lie detectors are another matter: § 111.37 bars employers from requiring, requesting or suggesting that a prospective employee take one, or using or asking about the results.

Can you record or transcribe a job interview in Wisconsin?

Yes, as a participant. Wis. Stat. § 968.31(2)(c) allows a private person to intercept a communication "where the person is a party to the communication," unless the purpose is a criminal, tortious or "other injurious act." Unlawful interception is a Class H felony, with civil damages of at least $100 a day or $1,000. Separately, § 885.365 makes recorded phone conversations "totally inadmissible" in civil cases unless an exception applies, such as telling the person at the time. So tell the candidate. See Wisconsin recording consent law for interviews and recording calls across state lines for candidates in Illinois and other all-party states.

Does Wisconsin regulate AI in hiring?

Not with a specific statute as of October 2026. We found no Wisconsin law on AI or automated tools in hiring, and none of the acts the Legislature lists for the 2025-26 session deals with AI in employment. Existing law still applies: a screen that rejects people because of age, disability, conviction record or another basis in § 111.321 is discrimination however the decision was made. See AI hiring laws by state.

Can you drug test applicants in Wisconsin?

Generally yes. We found no Wisconsin statute that sets procedures or limits for private employers' pre-employment drug tests. The state's hiring-related drug law runs the other way: § 108.133(4) lets an employer "voluntarily submit" to DWD a failed test given "as a condition of an offer of employment," or report a refusal, with civil immunity for good-faith reports. DWD's program page takes the report within 3 business days and uses it to decide unemployment benefits.

Narrower rules: public works and public utility contractors need a written substance abuse program with testing under § 103.503; an employer may not make an applicant "pay the cost of a medical examination required by the employer as a condition of employment" (§ 103.37); and § 111.35 with § 111.321 protects off-duty use of lawful products, which limits screening out smokers. See our drug testing laws guide.

Does Wisconsin require E-Verify?

No. 2025 Assembly Bill 281 would have required E-Verify for state agencies, local governments and state contractors. It passed both houses, was vetoed on April 3, 2026, and on May 13, 2026 the Assembly failed to override; its status reads "Veto Sustained." Private employers use E-Verify only by choice or under a federal contract clause. See E-Verify requirements in Wisconsin.

Which state withholding form does a new hire complete?

Form WT-4, the Employee's Wisconsin Withholding Exemption Certificate/New Hire Reporting. The Department of Revenue's Publication W-166 says "Federal Form W-4 cannot be used for Wisconsin withholding tax purposes" and "every newly-hired employee is required to provide a completed Form WT-4 to each of their employers." Employers send the department, at quarter end, a copy of any WT-4 claiming more than 10 exemptions, or complete exemption by someone earning over $200 a week. An employee who furnishes no form is treated as claiming zero exemptions.

Which notices must a new Wisconsin employee get at hire?

• Posters. DWD's workplace posters page says "All employers are required to display" the Fair Employment Law poster, and every employer covered by the unemployment law posts the Notice to Employees About Applying for Wisconsin Unemployment Benefits (UCB-7-P). Leave and business closing posters start at 50 employees.
• Remote workers. Where employees do not regularly visit a worksite, DWD's employer handbook says "an individual copy is to be provided to each employee" of the unemployment notice.
• Non-compete terms, if any. Wis. Stat. § 103.465 enforces a covenant not to compete "only if the restrictions imposed are reasonably necessary for the protection of the employer," and voids an unreasonable one entirely.
• Background check consent. If an outside agency runs a check, the FCRA's stand-alone disclosure and written authorization come first.

How do you report a new hire in Wisconsin?

To Wisconsin New Hire Reporting, run by DWD under Wis. Stat. § 103.05. Wis. Admin. Code DWD 142.03 makes the report due "within 20 days after the newly hired employee starts work," or twice monthly for electronic filers, and requires the employee's name, address, Social Security number, start date and date of birth, plus the employer's name, payroll address and FEIN. Rehires and recalls after an unpaid absence of more than 60 days count. DWD's new hire page recommends filing online and accepts a completed WT-4 by mail or fax, but not email. Penalties run up to $25 per employee, or $500 for a conspiracy not to report.

The Wisconsin hiring steps in order

1. Before the first hire: register with DWD for unemployment insurance and with the Department of Revenue for withholding; bind workers' compensation by the third employee or the $500 quarter. Agencies get a chapter 105 license or registration.
2. Posting: no Wisconsin pay range rule, but check the rules of other states where remote candidates live.
3. Screening: ask only about pending charges and convictions, judge each against the job, and never request a lie detector test.
4. Interview: a participant may record; tell the candidate at the start, and get consent when the candidate is in an all-party state.
5. Offer: background check under the FCRA; drug test if your policy calls for it; keep any non-compete reasonable.
6. First day: Form I-9, W-4 and WT-4, with the required notices posted or handed to remote staff.
7. Within 20 days of the start date: report the hire to Wisconsin New Hire Reporting.
