Massachusetts Paycheck Calculator

How to estimate your Massachusetts take-home pay in 2026

Massachusetts applies a flat 5% state income tax rate on wages after a personal exemption, with an additional 4% surtax on income above $1,083,150. This calculator estimates your 2026 net pay after federal withholding, FICA payroll taxes, and Massachusetts state tax so you can plan monthly expenses and compare job offers with confidence.

Enter your annual salary or build it from hourly wages using our gross pay calculator. If you receive 26 paychecks per year, the biweekly pay calculator shows how gross and net amounts spread across the calendar. For federal tax details and dependent credits, see the income tax calculator and salary calculator.

What gets deducted from a Massachusetts paycheck

A typical Massachusetts W-2 paycheck includes three layers of mandatory withholding plus any voluntary deductions you elect through your employer:

• Federal income tax: Calculated from 2026 IRS brackets, your W-4 filing status, and qualifying child tax credits.
• FICA taxes: Social Security at 6.2% (capped at the 2026 wage base of $184,500) and Medicare at 1.45%, with an additional 0.9% on wages above $200,000 for single filers. Use our FICA tax calculator to isolate these amounts.
• Massachusetts state income tax: A flat 5% applied to gross wages after pre-tax deductions and the personal exemption, plus a 4% surtax on income above $1,083,150.

Massachusetts also levies a paid family and medical leave contribution, but this calculator models state income tax only. Pre-tax 401(k) contributions and HSA deposits reduce gross wages before Massachusetts taxable income is calculated.

How Massachusetts state tax is calculated

Massachusetts taxable income starts with gross wages after pre-tax deductions, then subtracts the personal exemption before applying the flat rate and optional surtax:

For 2026, Massachusetts personal exemptions are $4,400 (single), $8,800 (married filing jointly), and $4,400 (head of household). The 4% surtax applies only to income above $1,083,150, giving high earners an effective top rate of 9%. Most workers never reach the surtax threshold, making Massachusetts comparable to other flat-tax states like Illinois at moderate incomes.

Massachusetts taxable income in this calculator

Massachusetts taxable income is based on gross wages after pre-tax 401(k) and HSA contributions, minus the personal exemption. This approach differs from states that tax federally taxable wages directly, such as Michigan.

Worked example: $65,000 salary, single, biweekly, 5% 401(k)

Consider a single Massachusetts employee earning $65,000 per year, paid biweekly, contributing 5% to a traditional 401(k), with no dependents or health premium deductions:

1. Pre-tax 401(k): $65,000 x 5% = $3,250 per year
2. Gross after pre-tax: $65,000 - $3,250 = $61,750
3. Massachusetts taxable income: $61,750 - $4,400 (personal exemption) = $57,350
4. Massachusetts state tax: $57,350 x 5% = $2,867.50 per year (no surtax at this income level)
5. FICA: Social Security and Medicare on the full $65,000 gross (401(k) does not reduce FICA wages)
6. Estimated net per paycheck: About $1,872.31 biweekly after all withholdings
