Choosing a PEO in Pennsylvania
Pennsylvania'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 Northeast. However, Pennsylvania's compliance environment has important nuances that employers must navigate carefully. Workers' compensation insurance is mandatory for all Pennsylvania employers, with no minimum employee threshold — a single employee triggers the requirement. This broad workers' comp mandate makes PEO co-employment arrangements particularly valuable for even very small Pennsylvania businesses.
Pennsylvania has no statewide paid sick leave law, but Philadelphia requires employers with 10 or more employees to provide up to 40 hours of paid sick leave per year. Pittsburgh has also enacted local sick leave ordinances, and effective January 1, 2026, Pittsburgh employees may now accrue up to 72 hours of paid sick time per year for employers with 15 or more employees. Employers operating across multiple Pennsylvania cities must track which local requirements apply to each location. Pennsylvania follows the federal WARN Act, requiring 60 days advance notice for layoffs affecting 50 or more employees.
Pennsylvania is not a right-to-work state, meaning union security agreements are permitted. The state has a significant manufacturing, healthcare, and energy sector presence — industries where union considerations can affect HR strategy. Pennsylvania employers must also comply with the Pennsylvania Human Relations Act, which provides broader anti-discrimination protections than federal law and applies to employers with 4 or more employees, compared to the federal Title VII threshold of 15. Effective November 2025, Pennsylvania also enacted the CROWN Act, prohibiting discrimination based on hairstyles associated with race.
For Pennsylvania businesses — particularly those in Philadelphia, Pittsburgh, or with multi-location operations — a PEO with deep Pennsylvania expertise can help manage workers' comp compliance, local paid sick leave tracking, anti-discrimination obligations, and benefits administration. The co-employment structure is especially valuable for smaller Pennsylvania employers who face mandatory workers' comp requirements from their very first hire.

Frequently Asked Questions
What is the minimum wage in Pennsylvania in 2026?
Pennsylvania's minimum wage remains at $7.25 per hour, matching the federal minimum. There have been ongoing legislative discussions about increasing the state minimum wage, but no increase has been enacted as of 2026. Employers in Philadelphia and Pittsburgh should verify current local minimum wage rates, which may exceed the state rate.
Is workers' compensation required in Pennsylvania?
Yes. Pennsylvania requires all employers to carry workers' compensation insurance regardless of the number of employees — even a single employee triggers the requirement. Coverage can be obtained through a private insurance carrier, the State Workers' Insurance Fund (SWIF), or an approved self-insurance arrangement. A PEO provides workers' comp coverage as part of the co-employment agreement.
Does Pennsylvania have a paid sick leave law?
Pennsylvania has no statewide paid sick leave law. However, Philadelphia requires employers with 10 or more employees to provide up to 40 hours of paid sick leave per year. Pittsburgh updated its paid sick time ordinance effective January 2026, now allowing employees to accrue up to 72 hours per year for larger employers. A PEO can administer compliant paid leave policies across all locations.
How does the Pennsylvania Human Relations Act differ from federal anti-discrimination law?
The Pennsylvania Human Relations Act (PHRA) provides anti-discrimination protections that apply to employers with 4 or more employees — a much lower threshold than the federal Title VII requirement of 15 employees. The PHRA covers discrimination based on race, color, religion, ancestry, age, sex, national origin, disability, and other protected classes. Pennsylvania also enacted the CROWN Act in late 2025, adding hair texture and protective hairstyles as protected characteristics.
