STATEWIDE TAXPAYER FAQ
MASSACHUSETTS PROPERTY TAX & EQUALIZATION FAQ
What is the statutory deadline to appeal property taxes in Massachusetts?
The resolved statutory filing deadline for Massachusetts is February 1, 2027 (or 30 days after actual tax bill is mailed). Initial local reviews are filed with the Local Board of Assessors (Abatement Application), with administrative escalation to the Massachusetts Appellate Tax Board (ATB).
How is residential property assessed in Massachusetts?
Under Massachusetts law, residential real property is assessed at 100% of fair market value (and commercial property at 100%). Equal and uniform taxation across properties is protected under Mass. Const. pt. II, c. 1, § 1, art. IV ("To impose and levy proportional and reasonable assessments, rates, and taxes").
How does Truth-in-Taxation work during Massachusetts county reappraisals?
Under M.G.L. c. 59, § 21C (Proposition 2½ statutory annual tax levy cap), when a county completes a reappraisal cycle (Five-year certification cycle by DOR with annual interim adjustments), the taxing authority must calculate a certified revenue-neutral tax rate so the reappraisal itself does not automatically create an unadvertised windfall tax increase.
