Tax Overview
Massachusetts has a flat income tax rate of 5% on most income, plus an additional 4% surtax on income over $1 million (the 'millionaire tax' effective 2023). This creates an effective 9% rate on income above $1 million. MA does not offer separate standard deductions like the federal system.
Tax Planning Tip
For most earners, the flat 5% rate is straightforward. If your income approaches $1 million (including capital gains), the additional 4% surtax creates a cliff — $1 of income over $1M costs an extra $40,000 in tax. Timing income around this threshold can be valuable.
The $1 million surtax threshold is adjusted annually for inflation. Massachusetts does not tax Social Security benefits. Short-term capital gains are taxed at 8.5%, while long-term gains are taxed at the standard 5% rate.
