Massachusetts Paid Family and Medical Leave Setup

If you have employees in Massachusetts, you are required to register an account for Paid Family and Medical Leave (PFML), a program offering up to 26 weeks of paid leave for family or medical reasons to eligible employees. Employers with less than 25 employees in Massachusetts have no contribution obligation, but are required to withhold and remit 0.344% of wages as the employees' contribution. Employers with 25 or more employees are required to remit 0.68% of wages as the PFML contribution. Employers are allowed to split the contribution with employees, with the employee portion capped at 0.344% of wages. Note: Employers can apply for an exemption from PFML contributions if they offer approved private plans with paid leave benefits that are equal to or more generous than those of the state PFML program.

  1. Set Up a Paid Family and Medical Leave Account

    New employers in Massachusetts typically get their Paid Family and Medical Leave account while registering for Withholding Tax. To set up a new Paid Family Medical Leave account, log into your MassTaxConnect account and select "More.." and then "Add a new account" under the "Access" section.

  2. Setup Employer-Employee Contribution Split with Your Payroll Provider

    If you elect to cover your employees' Paid Family Medical Leave contribution in part or in full, you will need to configure it with your payroll provider.

What is Multi-State Payroll?

Remote work is becoming increasingly popular with businesses and employees: According to estimates, flexible work arrangements have become three to ten times more common since 2019. Offering remote work options can give employers access to a national talent pool, reduce overhead costs, and help businesses attract and retain the best people for their teams. This shift also means that an increasing number of companies face multi-state payroll obligations. If you employ out-of-state remote workers, have business locations in multiple states, or have employees who travel for work, you may be required to withhold taxes in multiple states.

Research shows that offering paid leave increases participation in the workforce, improves financial security, supports child development and improves maternal health, and can increase employee productivity and retention.
