Employer Medical Assistance Contribution Rate in Massachusetts

Employer Medical Assistance Contribution (EMAC)

The Employer Medical Assistance Contribution (EMAC), which replaced the Unemployment Health Insurance (UHI) tax in 2014, helps to fund subsidized healthcare for low-income individuals in MA. Companies who have been around for 2 years or less, or have an quarterly average of fewer than six employees are exempt from EMAC.

EMAC Rates

Employer contributions to EMAC are determined by the company's EMAC rate.

  • New employers that become subject to EMAC or UHI previously will be exempt for the first 3 years.
  • Employers who have been subject to EMAC (or UHI) for four years have a rate of 0 .18% ( 0 .0018).
  • Employers who have been subject to EMAC (or UHI) for five years have a rate of 0 .36% ( 0 .0036).
  • Employers who have been subject to EMAC (or UHI) for six years+ have a rate of 0 .51% ( 0 .0051).

EMAC Supplemental Contribution

1) non-disabled and 

2) have health insurance either from MassHealth (excluding premium assistance programs), or who have subsidized coverage through Massachusetts ConnectorCare, for a minimum of 8 weeks during the quarter.
