PA Act 57 Assessment

A state-mandated surcharge (2.18% in 2026) added to all Pennsylvania workers' comp policies, funding the Workers' Compensation Security Fund and other state programs.

Definition

The Pennsylvania Act 57 assessment is a mandatory surcharge applied to all workers' compensation insurance policies in Pennsylvania. For 2026, the assessment rate is 2.18% of the adjusted standard premium.

What the Act 57 Assessment Funds and How It Is Applied

The Act 57 assessment funds the Workers' Compensation Security Fund (which pays claims when an insolvent carrier cannot), the Supersedeas Fund, the Workmen's Compensation Administration Fund, and the Uninsured Employers' Guaranty Fund.

The assessment rate can change annually based on the funding needs of these programs. It is collected by your insurer and remitted to the Pennsylvania Insurance Department.

The assessment is applied after the experience modifier and expense constant — on the "adjusted standard premium." It is not applied to the expense constant itself.
