Wisconsin New Hire Reporting: Deadline, What to Report and How to File (2026)

Wisconsin employers must report each new or rehired employee within 20 days after the employee starts work, online at wi-newhire.com or by fax or mail, and the report must include the employee's date of birth on top of the seven federal items. Independent contractors are not reported. The penalty is up to $25 per employee (up to $500 if employer and employee conspire), and only after the department has notified you and given you a chance to correct it.

Wisconsin new hire reporting at a glance

Wisconsin runs close to the federal model described on our national new hire reporting guide, with three differences worth knowing before your next hiring push: date of birth is required, the state writes its own weekend-and-holiday rule into the deadline, and no penalty can be imposed until you have been told about the problem and given time to fix it.

What a Wisconsin new hire report must contain

DWD 142.03(1) lists eight items. Seven are the federal set; the eighth, the employee's date of birth, is Wisconsin's addition. The department may waive the date of birth if you cannot provide it (DWD 142.03(4)).

• Employee: name (first, middle, last), mailing address, Social Security number, date of hire, and date of birth.
• Employer: name, FEIN, and the payroll address for that employee. The Center asks for the address where income withholding orders should go, and for the same FEIN you use on quarterly wage reports. Filing under a different FEIN is one of the ways employers end up flagged as non-compliant.
• Optional: employee state of hire, and employer contact name, phone, fax and email.

The Center's FAQ addresses a question HR teams do ask: collecting a date of birth after the hire is not an age discrimination problem. The problem is asking for it during selection, so keep it out of your application form and collect it at onboarding.

Ways to file in Wisconsin

Register at wi-newhire.com to key in hires online or send a data file through the site or by FTP. Online filing gives you a printable confirmation, which is the simplest record that you reported on time. On paper, the rule accepts three things (DWD 142.03(2)):

• A copy of the employee's completed WT-4, the Wisconsin withholding certificate, which doubles as a new hire reporting form.
• A copy of the federal W-4, with the employer name, address and FEIN, and the date of hire written in. The Center also wants the date of birth on it.
• Any paper report containing all eight required items, including a printed list from payroll software in at least 10-point type with your name, FEIN and address at the top.

Fax paper reports toll-free to (800) 277-8075 or mail them to Wisconsin New Hire Reporting, P.O. Box 14431, Madison, WI 53708-0431. The help desk at (888) 300-4473 is staffed Monday through Friday, 8:00 a.m. to 4:00 p.m. Central.

The 20-day clock and the day it starts

The rule's wording is precise: a report is due "within 20 days after the newly hired employee starts work." If you file electronically, you may instead submit twice a month, not less than 12 nor more than 16 days apart. Wisconsin also says what happens at a weekend: if the deadline falls on a Saturday, Sunday, a listed state holiday or any day without mail delivery, it moves to the next business day (DWD 142.03(3)(c)).

For frontline hiring the start date is the part that moves. A warehouse associate accepts on Monday, fails to show for Thursday orientation, then starts the following Tuesday. The clock begins on that Tuesday, the first day of paid work, not on the offer or the date your applicant tracking system marked the candidate hired. The Center's FAQ defines date of hire as "the first day an employee performs services for pay." Someone who works one day and quits still has to be reported.

Independent contractors in Wisconsin

Wisconsin does not require contractor reporting. The federal Office of Child Support Services guide lists Wisconsin as "No," and DWD 142.02(2) defines a reportable employee by the federal income tax withholding definition, which excludes genuine contractors. If a worker's classification is doubtful, the safer course is to settle the classification first, because an employee paid as a contractor is still an unreported new hire.

Penalties, and the notice that comes first

Wis. Stat. 103.05(5) allows a forfeiture of up to $25 for each employee concerning whom a violation occurred, and up to $500 where the employer and employee conspire to withhold the report or file a false one. Before any penalty, the department must give you notice of the violation and an opportunity to correct it (103.05(5)(c), repeated in DWD 142.05). Any penalty imposed is reviewable under chapter 227. In practice the Center says it works from a quarterly federal report of employers who may not have reported every hire and mails notices to those who appear non-compliant. If one arrives, a mismatched FEIN is the first thing to check.

Rehires, recalls, seasonal staff and substitutes

Wisconsin publishes its own threshold. Under DWD 142.02(7), a returning worker is a new hire if they are rehired, recalled or return after an unpaid absence of more than 60 days. The Center's wording is that anyone who has gone 60 or more consecutive days without pay must be reported again, which covers seasonal crews coming back each spring. Two occupations get special rules: substitute teachers are reported for the first day worked in each school year, and poll workers only once. Temporary agencies report a worker once, not per assignment, unless there is a break of 60 consecutive days or more and a new W-4 is needed.

Employers with staff in more than one state

Multistate employers may report every hire electronically to one state where they have employees, after telling the U.S. Department of Health and Human Services in writing. Wisconsin adds a step: Wis. Stat. 103.05(2)(b) says an employer that designates another state must also notify the Wisconsin department of that designation. If you choose Wisconsin as your single state, DWD 142.04 requires electronic filing and the state where each out-of-state employee works. The registration mechanics are on the parent guide.
