Boston City Council’s Committee on Ways and Means spent Oct. 8, 2026, grilling interim Assessing Commissioner Hinlan Wong over residential property tax assessments that councilors say undervalue luxury homes while tracking sale prices closely in working-class neighborhoods. The hearing on Docket #0586, sponsored by Councilors Miniard Culpepper, Erin J. Murphy and Brian Worrell, followed months of complaints that market values and assessed values diverge sharply by neighborhood.
The Boston Herald reported on Oct. 10 that Culpepper repeatedly asked why Back Bay and Beacon Hill multimillion-dollar properties often carry assessments well below recent sale prices, while Roxbury and Dorchester homes are assessed near or above what they sell for. Wong said the city follows state law and uses prior-calendar-year sales, and that high-end sales can be statistical outliers.
What the hearing order cited
The council order, filed earlier in 2026 and referred to Ways and Means on March 18, asked for a review of discrepancies between market value and tax-assessed value for residential properties citywide. The text cited a Back Bay townhouse that sold for about $21 million while assessed near $12.5 million. It also referenced analysis that luxury homes averaged roughly 68 percent of sale price in assessed value, with under-assessments among top luxury transactions totaling about $35.4 million in 2024 and $43.7 million in 2025 in the figures listed in the order.
By contrast, the order described a Roslindale single-family home that sold for about $430,000 but was assessed at $489,000 — about 114 percent of the sale price. Those examples framed the equity argument Culpepper pressed at the hearing: if assessors can track market value tightly in lower-priced neighborhoods, why not at the high end?
The public hearing was held at 2 p.m. in the Iannella Chamber at City Hall and broadcast on City Council TV and cable channels. Residents were invited to testify in person or virtually and to submit written comments.
What councilors and advocates said
According to the Herald’s account of the Oct. 8 session, Culpepper focused on neighborhood patterns. “Why, when you come to Back Bay and Beacon Hill, the assessments are so low at multi-million dollar properties, and then when you get into Roxbury and Dorchester, the assessments are almost exact as the sale price?” he asked Wong, as quoted by the Herald.
Councilor Ed Flynn linked the debate to this year’s tax bills, saying the average single-family homeowner faced a 13 percent tax hike that placed a disproportionate burden on lower-income owners. Culpepper argued the city is also losing revenue when Back Bay and Beacon Hill assessments lag sale prices.
Chris Lehman of the Small Property Owners Association told the Herald his group’s analysis found low-end single-family homes assessed near same-year sale prices (about 99% to 105% on average), while high-end homes averaged 68% to 80% of sale price, with some far lower. Lehman said underassessment of the top 20 luxury homes by about $83 million in fiscal year 2026 reduced the tax base at a time when commercial values are also under pressure.
How the Assessing Department responded
Wong told councilors that Massachusetts law requires valuation at fair cash market value and that yearly assessments rely on sales from the prior calendar year. Fiscal year 2026 assessments, he said, used calendar year 2024 sales — so some 2025 luxury closings Culpepper highlighted would not yet drive the latest certified values.
On Beacon Hill and similar markets, Wong said assessors look at the overall sales pattern, not a single $20 million closing. A neighborhood may include $13 million and $7–8 million sales alongside an outlier, and the department will not value every comparable at the top sale without support, he said, according to the Herald.
That explanation did not satisfy Culpepper, who kept returning to the equity gap between neighborhoods. No final ordinance or assessment methodology rewrite was adopted at the hearing itself; the session was framed as fact-finding on Docket #0586.
Why assessments matter for Boston budgets
Residential assessments feed the city’s property tax levy, which underpins schools, public safety and neighborhood services. Readers following City Hall money fights can compare this hearing with the Boston Report’s coverage of the FY27 budget, property taxes and BPS costs and the same-day story on record Boston office rents as law firms trade up, which sits on the commercial side of the same tax equation.
Council activity this month also includes the Boston School Committee’s Oct. 14 agenda, another reminder that residential tax capacity and school funding debates often run in parallel even when they are not formally linked on a single docket.
If luxury homes are systematically underassessed relative to sales while modest homes are assessed near sale price, the effective tax share shifts toward owners with less ability to absorb increases — the core claim Culpepper and Lehman advanced. Wong’s counter is statutory timing and mass-appraisal methodology, not a denial that large gaps can appear on individual high-end parcels.
What happens next
The Ways and Means hearing does not by itself revalue properties. Any change to assessing practice would need to stay inside state Department of Revenue rules and the city’s annual classification and tax-rate process. Watch for committee reports on Docket #0586, further data requests to Assessing, and whether the full Council presses for outside review of high-end residential methods.
Homeowners who disagree with a current assessment still use the standard abatement process on the timeline printed on their tax bill. The Oct. 8 hearing was about systemwide patterns, not individual abatements. For now, the public record shows a sharp political fight over whether Boston’s residential assessing practices treat Back Bay mansions and Roslindale triple-deckers by the same market yardstick.
