What Brookline's $23.25M Tax Override Means for Single-Family Homeowners
With Election Day on May 5th, Brookline homeowners face a deceptively simple ballot question: should the town be allowed to raise an additional $23.25 million in property taxes? Before you vote, it's worth stepping back and looking at the full picture — one that goes well beyond the town's compelling but one-sided talking points.
The Override in Brief
The ballot question asks whether Brookline should assess an additional $23,254,439 in property taxes — $17.9 million for the Public Schools of Brookline and $5.3 million for municipal departments — for the fiscal year beginning July 1, 2026. (Brookline) If passed, it would increase property taxes by 8% in the first year and roughly 18% over three years. (The Cypress) This is the largest override ever proposed in Massachusetts.
You're Already Paying More Than Almost Anyone in the State
Before weighing what comes next, it's important to understand where Brookline homeowners already stand. Brookline had the second-highest average single-family tax bill in Massachusetts in 2026, at $26,237. (Brookline.News) The median assessed value of a single-family home in Brookline is $2.34 million. (Brookline.News) These aren't numbers that exist in a vacuum — they reflect years of extraordinary real estate appreciation driven by high demand and severely constrained supply. And that appreciation hasn't gone unnoticed by the town's tax assessors.
Even if the overall tax rate changes modestly, individual bills can rise significantly when a home appreciates faster than the town average. For many long-time homeowners — particularly empty nesters or those planning to downsize — these increases can feel frustrating, especially if the home itself hasn't changed or been renovated. (Ingvildbrown) Rising assessed values have quietly delivered the town substantially more revenue every few years, even before any override vote.
A Pattern of Recurring Overrides
Brookline has now passed overrides in 1994, 2008, 2015, 2018, 2023, and faces another in 2026 — permanently raising the tax base each time. (The Cypress) Each override is framed as an urgent, one-time fix. But the 2023 override was supposed to cover three years of spending — and here we are again. Critics argue that this cycle reflects a structural failure that more revenue alone won't solve. As one override opponent put it, when something isn't working, the first step is to stop digging the hole deeper. (TheCypress)
If voters approve the override, total property taxes collected over the next three years would rise 18%, compared to 11% without it. (Brookline.News) And that's before accounting for existing debt exclusions already built into your bill for school and fire station construction.
The Schools Argument Deserves Scrutiny
The override's advocates rely heavily on the quality-of-schools argument: vote yes or Brookline loses its educational edge, and with it property values. It's a powerful case — but the enrollment trends tell a more complicated story.
Brookline's student enrollment for 2024–25 is 7,023 students — the third consecutive year of declining enrollment following a post-pandemic spike. In the 2019–20 school year, 7,777 students were enrolled. (Brookline.News) That's a loss of nearly 800 students from the pre-pandemic peak, and the numbers haven't recovered.
Where are those students going? More than 1 in 5 children in Brookline, Cambridge, and Newton now attend private or parochial schools. (The Boston Globe) Brookline and Newton have reportedly lost sizable portions of their pre-COVID enrollment to nearby private schools, (The 74 Million) with departures largely driven by concerns over academic rigor and behavioral issues in the schools. A Boston University education researcher found that we're now five years out from the pandemic and there's still a persistent shift in families' choices — suggesting something more than a temporary disruption is at work.

This raises a fair question: if a growing number of Brookline families are already choosing to pay private school tuition on top of their property taxes, does funding an even larger public school budget address the actual reasons they left?
The "Millionaire's Tax" — And Why It Hits Brookline Homeowners Hard
Many Brookline homeowners are aware they have built substantial equity in their homes over the years. What's less widely understood is how aggressively that equity is now taxed when they sell.
Beginning January 1, 2023, Massachusetts imposed an additional 4% surtax on annual income exceeding $1 million (Rich May, P.C). — the so-called "Millionaire's Tax" or Fair Share Amendment. In most parts of the country, this wouldn't affect ordinary homeowners. In Brookline, it does.
Gain from the sale of a primary residence is included in the calculation of annual taxable income for the purpose of assessing the surtax. While the standard $250,000 federal exclusion (or $500,000 for married couples) still applies, any gain above that exclusion is counted toward the $1 million threshold. (Day Pitney) Given that the median sale price of a Brookline single-family home is now $2.28 million (Ingvildbrown)a long-term homeowner who bought decades ago at a fraction of that price can easily realize taxable gains that push them over the million-dollar income threshold in the year they sell — triggering a 4% surtax on the overage. This is not a tax designed with Brookline homeowners in mind. It was framed as a levy on the ultra-wealthy, but in practice it applies to many ordinary families who simply had the good fortune — and the foresight — to buy a home in a town that appreciated dramatically over the years.
These are the same homeowners who have contributed reliably to Brookline's tax base for decades. Now, when they sell, they face a compounding tax burden: higher capital gains exposure, the Fair Share surtax, potential estate tax implications, and now the prospect of yet another property tax override that will further inflate assessed values and future bills.
What a YES Vote Really Means for Affordability
Brookline is already one of the most expensive communities in Massachusetts. Higher annual property taxes — combined with elevated interest rates — narrow the pool of qualified buyers and affect affordability calculations. Every override vote that permanently raises the tax base makes it harder for the next generation of families to move in, harder for retirees on fixed incomes to stay, and harder for the town to maintain the economic diversity that makes a community resilient.
The case for voting YES is real: cuts to schools and fire services have genuine consequences. But the case deserves to be weighed against an equally honest reckoning with what a perpetual cycle of overrides, combined with the Fair Share surtax and relentless property appreciation, is doing to the people who built Brookline's tax base — and who are now being asked, again, to dig deeper.
