Learn about the Employer Medical Assistance Contribution (EMAC)

Each employer subject to unemployment insurance is also subject to Employer Medical Assistance Contribution (EMAC) reporting requirements. EMAC is used to help fund health insurance programs in the Commonwealth.


Employers must pay contributions on the first $15,000 of each employee's wages paid during the calendar year. The amount of contributions due (or liability) is derived by multiplying these wages by an assigned rate. The result is the amount that must be paid as an employer medical assistance contribution (EMAC).

When a quarterly contribution report is not filed to the Department of Unemployment Assistance (DUA) through UI Online as required, the amount of liability cannot be established and therefore will be estimated.


Employers are not liable for payment of EMAC in a quarter whenever the average employee count is fewer than six (because wages are exempt for that quarter).

Also, employers are exempt when they meet the definition of "newly subject ". That is, an employer is not liable for payment of EMAC for up to 3 years after first becoming subject to the unemployment insurance law.
