How does Massachusetts tax capital gains?

Massachusetts taxes capital gains under special rules rather than at the ordinary income rate. Short-term capital gains (held <1 year) taxed at 8.5% since January 1, 2023. Long-term gains (>1 year) taxed at 5%. The 4% surtax on income over the annual threshold ($1,107,750 for 2026) applies on top of either rate for high earners. You still owe federal capital gains tax on top of any state tax. See how capital gains tax works in 2026.
