If you just hired your first Massachusetts employee and Googled "what taxes do I owe," you're already confused. MA layers state income tax withholding, a Byzantine unemployment portal, and the Paid Family and Medical Leave program atop your federal payroll tax obligations. Here's your 2026 roadmap for massachusetts payroll taxes — rates, portals, and pitfalls.
- MA income tax withholding is a flat 5% — no brackets, no complexity there
- PFML total rate is ~0.88% — if you have fewer than 25 employees, you owe zero employer share
- DUA unemployment rate for new employers is 2.42% on the first $15,000 per employee
- Three separate portals — MassTaxConnect, the PFML Employer Portal, and UI Online (this is the #1 setup mistake)
Massachusetts Payroll Tax Rates at a Glance (2026)
Four obligations. Four rates. Here's the breakdown.
| Tax Type | Who Pays | 2026 Rate | Wage Base |
|---|---|---|---|
| MA Income Tax Withholding | Employer withholds from employee | 5% flat | No cap |
| PFML – Medical Leave | Split: 25+ employers pay ≥60%; under 25, employee pays 100% | 0.70% total | All wages |
| PFML – Family Leave | Employee only — 100% at all employer sizes; no employer share required | 0.18% total | All wages |
| DUA (SUTA / Unemployment) | Employer only | 2.42% (new employer) | First $15,000/employee |
PFML: The Compliance Detail Every MA Employer Must Get Right
This is where MA employers bleed money. The Paid Family and Medical Leave program operates its own fiefdom — separate rates, separate portal, separate deadlines. Ignore the distinction and expect penalty notices.
Take Jamie — a composite of new employers we see — a Worcester bakery owner with 8 employees. She set up MassTaxConnect perfectly for income tax withholding but had no idea PFML filings go to a completely different agency. Three quarters later, the Department of Family and Medical Leave sent a delinquency notice. Don't be Jamie.

1
Determine your workforce size. Count all W-2 employees plus any 1099-NR contractors who work primarily for you. If that total is 25 or more, you owe the employer share of medical leave. Under 25? You only withhold from employees.
-
2
Calculate your split. Under MA Chapter 175M, the employer share applies only to the medical leave component. For 25+ employees: medical leave splits 60% employer / 40% employee. Family leave is 100% employee-funded at every employer size — you withhold it but owe nothing on top. Under 25 employees: employees pay 100% of both components.

3
Register on MassTaxConnect (masstaxconnect.dor.state.ma.us) for income tax withholding. This is NOT where you file PFML — but you need this account active first. Miss this and your withholding deposits have nowhere to land — the DOR starts assessing failure-to-pay penalties at 1% per month.
-
4
Register and file PFML at paidleave.mass.gov — the MA PFML Employer Portal. Quarterly filings go here, not MassTaxConnect. Miss this and your PFML account never gets created — delinquency notices follow in Q2.
-
5
Post the required PFML workplace notice. MA law requires you to display the PFML notice — available free from the Department of Family and Medical Leave — at your workplace. Skipping it is a citable violation.
MA PFML filings go to the Department of Family and Medical Leave — not the Department of Revenue. Many small employers accidentally file to MassTaxConnect and wonder why they're still delinquent. Two agencies. Two portals. Both matter.
Only withhold from employees — no employer share of PFML owed. Withhold 0.88% total from each paycheck and remit quarterly.
Treating W-2 employees as 1099 contractors to duck under the 25-employee threshold triggers PFML audits — and back contributions with interest.
"PFML is MA's biggest payroll compliance trap for small businesses — get the portal right before the rate."
MA Income Tax Withholding, DUA, and Health Insurance
The One MA Tax That's Actually Straightforward
Massachusetts takes a flat 5% cut in 2026 — no brackets, no phase-outs. Withhold 5% of taxable wages, adjusted for MA Form M-4 exemptions your employees submit at hire. Set up withholding through MassTaxConnect, pick a schedule based on volume, done. (Federal income tax withholding and FICA run separately through EFTPS — see our federal payroll taxes guide if you haven't handled those yet.)
DUA Unemployment: Register Before Your First Payroll
New MA employers pay 2.42% on the first $15,000 of each employee's wages — see our MA SUTA and unemployment tax guide for how your rate gets recalculated once you build a claims history. Register with DUA at UI Online before your first check; your rate adjusts later based on claims history.
Health Insurance Mandate: Only If You Have 11+ Employees
Eleven or more full-time equivalents? Offer coverage or pay the Fair Share Contribution — roughly $78 per employee annually per the MA HIRD assessment schedule. For a full breakdown, see our MA employer health insurance compliance guide. File via the HIRD form annually, not through payroll. Under 11? Ignore it until you grow.

Frequently Asked Questions
What is the Massachusetts PFML rate for 2026?
The total MA PFML contribution rate is approximately 0.88% of wages in 2026 — 0.70% for medical leave and 0.18% for family leave. If you have fewer than 25 employees, you're exempt from the employer share of medical leave and only withhold the employee portion from paychecks.
Do I need to register with MassTaxConnect and the PFML portal separately?
Yes — and this is the most common setup mistake. MassTaxConnect handles income tax withholding (DOR); paidleave.mass.gov handles PFML (Department of Family and Medical Leave); UI Online handles DUA unemployment. Three obligations, three portals.
Is Massachusetts income tax withholding a flat rate?
Yes — Massachusetts uses a flat 5% rate for 2026, adjusted for MA Form M-4 exemptions. The complexity in MA payroll comes from PFML, not the income tax side.
