Massachusetts Paycheck Calculator FAQ
What is Massachusetts's state income tax rate?
Massachusetts charges a flat 5% rate for tax year 2026.

What deductions does Massachusetts apply before taxing my income?
Massachusetts applies a $4,400 personal exemption, plus an additional 4% surtax on income over $1,083,150, before the flat 5% rate. See the "How Massachusetts Paycheck Tax Is Calculated" section above for the exact formula.
Does this estimate change if I'm married or have dependents?
This calculator uses single-filer figures only (v1 scope). Married filing jointly typically uses different federal and Massachusetts state brackets and a larger standard deduction — your actual take-home pay will differ. Dependents can also reduce federal withholding via the W-4. Check Massachusetts Department of Revenue's married-filing-jointly tables for a precise figure.
Methodology & Source
Massachusetts state tax figures sourced from Massachusetts Department of Revenue (https://www.mass.gov/orgs/massachusetts-department-of-revenue), citing Mass. Gen. Laws ch. 62 § 4 — flat 5% plus 4% surtax on income over $1M (2022 ballot amendment). Federal brackets, standard deductions (single/MFJ/HoH), and FICA constants sourced from the IRS (Revenue Procedure 2025-32; married-filing-jointly Additional Medicare threshold of $250,000 is a separate, unindexed statutory figure). Massachusetts's married-filing-jointly and head-of-household figures are not yet independently verified and currently fall back to single-filer brackets — see the caveat in the formula section above.
Bonus federal withholding uses the flat supplemental-wage rate (22%, 37% above $1,000,000 cumulative supplemental wages/year), per IRS Publication 15 (Circular E), Employer's Tax Guide, 2026 edition — the alternative "aggregate method" is not modeled.
This is an estimate based on standard single-filer federal, FICA, and MA state calculations. Actual withholding may differ based on your W-4 elections, pre-tax deductions, and other factors. The millionaire's surtax threshold is inflation-indexed annually; $1,083,150 is the most recently published figure at last-verified date — confirm current threshold at mass.gov before relying on this near the boundary.
