Massachusetts Tax Guide 2026

Understanding Your Massachusetts Paycheck

Massachusetts workers face a unique tax landscape. Unlike most states, Massachusetts uses personal exemptions instead of a standard deduction — meaning more of your income is subject to the state's flat 5% tax than many employees expect.

🏛️

MA State Income Tax

5.0%

Medicare

1.45%

No wage cap. Earners above $200,000 pay an additional 0.9% Additional Medicare Tax.

How Massachusetts Income Tax Works in 2026

Massachusetts taxes most earned income at a flat 5% rate. The simplicity ends there, though. Instead of a standard deduction (like the $15,000 federal standard deduction for single filers), Massachusetts uses a personal exemption system:

  • Single filers: $4,400 exemption
  • Married Filing Jointly: $8,800 exemption
  • Head of Household: $6,800 exemption

This means a single Massachusetts employee earning $70,000 has $65,600 in MA taxable income (after the $4,400 exemption) — versus only $55,000 in federal taxable income (after the $15,000 standard deduction). That gap means your effective MA tax rate is higher than a naive 5% calculation suggests.

🔍 The Fair Share Surtax: Since 2023, Massachusetts imposes an additional 4% tax on individual income exceeding $1,083,150 (2026 threshold). This brings the marginal rate to 9% for the highest earners — but does not affect the vast majority of workers.

Massachusetts PFML: What It Is and What You Pay

The Massachusetts Paid Family and Medical Leave (PFML) program provides wage replacement benefits when you need time off for family or medical reasons. In 2026, the employee contribution rate is 0.46% of your eligible wages:

  • Medical leave portion: 0.28% (your share; employer pays 0.42%)
  • Family leave portion: 0.18% (fully employee-funded)

The maximum 2026 weekly PFML benefit is $1,230.39 — an increase from $1,170.64 in 2025.

Pre-Tax Deductions: Your Best Tool for Lowering MA Taxes

Unlike some other states, Massachusetts does recognize many pre-tax deductions that reduce your taxable income. Contributing to a 401(k), health insurance premium (employer-sponsored), or Flexible Spending Account (FSA) before taxes reduces both your federal and Massachusetts taxable income — giving you a combined tax savings of roughly 18–30% on every dollar contributed, depending on your bracket.

💡 Pro Tip: A Massachusetts worker in the 22% federal bracket contributing $500/month pre-tax to a 401(k) saves approximately $1,350 per year in combined federal + state taxes ($500 × 12 × 27%).

Federal Income Tax Withholding for Massachusetts Employees

Federal income tax is separate from Massachusetts taxes and follows the 2026 federal brackets. The federal standard deduction for 2026 is $15,000 for single filers and $30,000 for married filing jointly. Your W-4 filing status and any additional withholding elections directly control how much federal tax your employer withholds each paycheck.

If you haven't updated your W-4 since 2020, consider reviewing it — the IRS redesigned the form and it no longer uses "allowances."
