Choosing a PEO in Wisconsin

Wisconsin's minimum wage is set at the federal floor of $7.25 per hour, making it one of the lower minimum wage states in the Midwest. Wisconsin is a right-to-work state (since 2015), meaning employees cannot be required to join a union or pay union dues as a condition of employment. Wisconsin's overall regulatory environment is relatively employer-friendly, though the state has important compliance requirements that businesses must manage carefully.

Workers' compensation insurance is mandatory for employers with 3 or more employees in Wisconsin, or for any employer who pays $500 or more in wages in any quarter. Coverage is obtained through private insurance carriers or through self-insurance for qualifying employers. Wisconsin follows the federal WARN Act, requiring 60 days advance notice for layoffs affecting 50 or more employees. Wisconsin has no statewide paid sick leave law — a 2008 Milwaukee paid sick leave ordinance was preempted by state law shortly after passage.

Wisconsin's Fair Employment Law provides anti-discrimination protections that apply to employers with 1 or more employees — a very broad threshold that means virtually every Wisconsin employer is subject to state anti-discrimination requirements. The law prohibits discrimination based on age, race, creed, color, disability, marital status, sex, national origin, ancestry, sexual orientation, arrest or conviction record, military service, and use or non-use of lawful products outside of work.

Wisconsin's economy is anchored by manufacturing, agriculture, healthcare, and financial services — industries with distinct HR needs. The Milwaukee and Madison metro areas have competitive labor markets, particularly in technology, life sciences, and financial services. While Wisconsin's regulatory environment is more employer-friendly than neighboring Illinois or Minnesota, the absence of paid leave and the complexity of workers' comp make PEO services valuable for Wisconsin businesses seeking to provide competitive employee benefits. Use the form on this page to connect with PEOs serving Wisconsin businesses.

Frequently Asked Questions

What is the minimum wage in Wisconsin in 2026?

Wisconsin's minimum wage is $7.25 per hour, matching the federal minimum. Wisconsin has not enacted a state minimum wage above the federal rate and the state preempts local governments from setting higher local minimum wages. Wisconsin's effective minimum wage is among the lowest in the Midwest.

Is workers' compensation required in Wisconsin?

Yes. Wisconsin requires workers' compensation insurance for employers with 3 or more employees, or for employers who pay $500 or more in wages during any calendar quarter. Coverage is obtained through licensed private insurance carriers or through state-approved self-insurance. A PEO provides workers' comp as part of the co-employment arrangement.

Does Wisconsin have a paid sick leave law?

Wisconsin has no statewide paid sick leave law. A Milwaukee paid sick leave ordinance was preempted by state law in 2011, and the state's preemption law prevents local governments from enacting similar ordinances. Employers that want to offer paid sick leave do so voluntarily or through a PEO-administered benefits program.

How broad are Wisconsin's anti-discrimination protections?

Wisconsin's Fair Employment Law applies to employers with 1 or more employees — meaning virtually every Wisconsin employer must comply. The law prohibits discrimination based on a broad range of protected characteristics including age, race, sex, disability, marital status, sexual orientation, arrest or conviction record, and use or non-use of lawful products outside of work. A PEO can help ensure employment policies and practices comply with Wisconsin's anti-discrimination requirements.
