Massachusetts filing notes
Apply the Massachusetts personal exemption before the 5% ordinary-rate estimate, and plan for the 4% surtax if taxable income approaches $1,107,750 in 2026. Do not assume all income is taxed at 9%; only the amount above the surtax threshold gets the extra 4%. The low $2M estate tax exemption affects more families.
