Massachusetts employers face several layers of payroll tax obligations, including state income tax withholding at the flat rate, unemployment insurance, and contributions to the state’s Paid Family and Medical Leave (PFML) program. The PFML program, launched in 2021, requires employer and employee contributions and provides wage replacement benefits for qualifying leave. Combined with the millionaires’ surtax on income over ~$1 million, Massachusetts presents a moderately complex payroll environment for employers.

How Massachusetts Payroll Taxes Work
State Income Tax Withholding
Massachusetts employers withhold state income tax at the flat ~5.0% rate from all employee wages. The calculation uses the employee’s Form M-4 (Massachusetts Employee’s Withholding Exemption Certificate). Personal exemptions and deductions reduce the amount subject to withholding, but the rate itself does not change.
The ~4.0% millionaires’ surtax applies to individual income over ~$1,000,000 but is generally not withheld by employers through regular payroll. High-earning employees may need to make estimated tax payments to cover the surtax.
Unemployment Insurance (SUTA)
Massachusetts unemployment insurance rates are experience-rated and have a wide range:
| SUTA Factor | Detail |
|---|---|
| Tax rate range | ~0.56% to ~18.55% |
| Taxable wage base | First ~$15,000 per employee |
| New employer rate | ~1.45% to ~5.60% (varies by industry) |
| Maximum annual tax per employee | ~$2,783 |
Massachusetts has one of the widest SUTA rate ranges in the country, with the maximum rate of ~18.55% being among the highest nationally. This makes experience rating management particularly important.
Paid Family and Medical Leave (PFML)
Massachusetts’ PFML program provides up to ~12 weeks of paid family leave and ~20 weeks of paid medical leave (up to ~26 weeks combined in a benefit year). The program is funded through a payroll contribution:
- Total contribution rate: Approximately ~0.88% of eligible wages (split between employer and employee)
- Medical leave portion: Approximately ~0.28% (employer pays ~60%, employee pays ~40%)
- Family leave portion: Approximately ~0.60% (employee pays ~100% unless employer opts to contribute)
- Wage base: First ~$168,600 (tied to the Social Security wage base)
Employers with fewer than ~25 covered employees are not required to pay the employer share of the medical leave contribution.
Workforce Training Fund
Employers contribute ~0.056% of wages (first ~$15,000 per employee) to the Workforce Training Fund, which supports employee training and education programs.

Tips for Massachusetts Employers
- Actively manage your SUTA experience rating — Massachusetts’ rate range is exceptionally wide (~0.56% to ~18.55%). Contesting inappropriate unemployment claims and reducing turnover can save thousands per employee.
- Understand PFML obligations — determine whether you must pay the employer share of medical leave (employers with ~25+ covered individuals). Ensure employee contributions are properly withheld.
- Don’t overlook the surtax for high earners — while the ~4% surtax is not typically withheld through regular payroll, advise employees earning over ~$1,000,000 to make estimated payments to avoid underpayment penalties. See the federal income tax guide.
- File quarterly returns on time — Massachusetts imposes penalties and interest on late filings and payments for both withholding and unemployment.
- Apply for Workforce Training Fund grants — the contributions you make fund training programs that your business can access for employee skill development.
- Consider the impact of remote workers — Massachusetts may require withholding for employees working remotely from within the state, even if the employer is based elsewhere.
