Best Massachusetts Property Tax Appeal Services in 2026 (Compared)
Last updated: June 26, 2026
Massachusetts property tax appeals are filed as Applications for Abatement with your city or town Board of Assessors. The deadline is February 1 (for properties assessed on January 1). If the Board of Assessors denies your abatement application or fails to act, you can appeal to the Appellate Tax Board (ATB), the state-level body for tax disputes. Massachusetts has very high property values, particularly in Middlesex County (Cambridge, Newton, Lexington), Norfolk County (Brookline, Wellesley, Needham), and Suffolk County (Boston). A Boston-area home assessed at $800,000 at a 1.1% rate saves $880/year on a 10% reduction.

★☆☆☆☆
Ownwell was not worth it and lost me a ton of money
“They absolutely put no effort into properly protesting my property. I lost so much money because of them. The county over-valued my property by almost $400,000, and Ownwell didn’t even submit comps. … Just do it yourself.”
★☆☆☆☆
Very deceptive results
“Very deceptive results, claimed I would save $600 on my property taxes, the actual savings were $55. Plus, they charged their 25% fee on the $600 they claimed the saved me.”
★☆☆☆☆
Absolutely unacceptable
“Then I discovered that my appeal had been withdrawn. … One of the worst professional-service experiences I have ever had.”
