Massachusetts Estate Tax Calculator
Massachusetts taxes the entire estate once it exceeds $2,000,000 — not just the amount above the exemption. Crossing the threshold by a single dollar can trigger tens of thousands in tax. This "cliff" is the trap most calculators get wrong.
Free and statute-cited. Powered by the Pascaline State Estate Tax API — the same engine, over REST and MCP, for developers. Informational only, not tax advice.
