Massachusetts State Disability Insurance (SDI)
Unlike California and several other states, Massachusetts doesn’t levy a standard State Disability Insurance (SDI) tax. In those states, SDI contributions fund wage‑replacement benefits for employees who are temporarily unable to work due to non–non-work-related illness or injury.
Instead, Massachusetts offers a Paid Family and Medical Leave program, which provides similar benefits to SDI but is funded differently.

COVID-19 Recovery Assessment
Private-contributory, experience-rated employers in Massachusetts must contribute to the COVID-19 Recovery Assessment to begin to recover the charges to the COVID-19 Employer Relief Account.
Employers with new SUI rates are exempt, along with reimbursable and governmental employers, employers with assigned SUI rates that received zero 3-year average wages on their rate notice, and non-profit employers who have changed their payment method to contributory within the last 3 years.
Contributions due are automatically calculated for subject employers when quarterly employment and wage detail reports are filed, based on a taxable wage base of $15,000 per employee. There is no additional filing requirement.
Applicable Employers | Calculation Basis | Exemptions |
---|---|---|
Private-contributory, experience-rated employers | $15,000 taxable wage base per employee | New employers, reimbursable, governmental employers, certain non-profits |
Employer Medical Assistance Contribution (EMAC)
Employers are required to file a quarterly EMAC contribution report with the Department of Unemployment Assistance (DUA) through UI Online. If this isn't submitted, the liability amount is estimated.
Established employers in Massachusetts with 6 or more employees are required to pay an Employer Medical Assistance Contribution (EMAC).
Employee Threshold | Annual Taxable Wage Base | Contribution Rate by Year |
---|---|---|
6+ Employees | $15,000 | 0.12% (Year 4), 0.24% (Year 5), 0.34% (Year 6+) |
Workforce Training Fund Program (WTFP)
The Workforce Training Fund Program (WTFP) supports professional development in Massachusetts. All of the state's employers contribute at a flat rate of 0.056% in 2024. See the update for 2025 on the official government website.

Workers’ compensation
Workers' compensation provides vital financial support in the event of job-related injuries or illnesses. It also provides legal protection for employees and employers. All employers in Massachusetts are required to carry workers' compensation insurance, regardless of the number of hours worked or the number of employees. This includes you as the employer if you are considered an employee of your own company. Exemptions apply.
Employers must purchase workers' compensation Insurance from one of the state's qualified commercial carriers. You may not self-certify.
Penalties for non-compliance are severe.
Penalty | Details |
---|---|
Stop-work order (SWO) | Issued by DIA until compliance |
Daily fine (SWO unappealed) | $100/day (including weekends, holidays) until compliance |
Daily fine (SWO appealed) | $250/day (business may operate during appeal) |
Criminal charges | Up to 1 year prison and/or fine up to $1,500 upon conviction |
Debarment from public contracts | 3-year period of debarment |
Massachusetts Reciprocal Agreements
Reciprocal income‐tax agreements let people who live in one state but work in another remit state taxes only to their home state, eliminating dual withholding and simplifying payroll for both employees and employers.
Massachusetts, however, has no such reciprocity pacts with any other state, so whether you reside here and work elsewhere or vice versa, you won’t qualify for a reciprocal exemption. That said, the federal system bars two states from taxing the same earnings, and your state of residence will typically grant you a credit for any income taxes you pay to the other state.
