The Two Assessors Behind Every Bronxville Village Tax Bill

Open a Bronxville Village tax bill and you will find two payment stubs, due on two different dates, calculated by two different offices that do not report to each other. Most owners write both checks without ever asking why the number wasn't produced by one government looking at one house. It should be. It isn't.

The Village of Bronxville assesses your property for village and school taxes, which together make up roughly 80 percent of the bill. The Town of Eastchester assesses the same property, separately, for the county, town, fire, and special district taxes that make up the remaining 20 percent. Two assessors, two rolls, two sets of assumptions about what your house is worth, both landing in the same envelope.

What the Village actually measures

In 2007, the Village of Bronxville completed a full village-wide revaluation, and it has held every property at 100 percent of fair market value every year since. The Village is unusual statewide in that it assesses for both its own municipal taxes and the school district's taxes, a structure it explains directly on its own site. The current Village Assessor, Mark Heinbockel, publishes a Tentative Assessment Roll every February 1 and a Final Roll every April 1, and the process runs on a fixed clock: Grievance Day is always the third Tuesday in February. For 2026, that fell on February 17.

That means roughly four out of every five dollars on a Bronxville tax bill are tied to a valuation that gets revisited annually and is meant to track the current market, not a decades-old benchmark.

What Eastchester measures instead

The other fifth of the bill runs on a different system entirely. The Town of Eastchester's 2026 Tentative Roll lists a uniform percent of value of 0.84 for the Bronxville school district area, with a valuation date of July 1, 2025. In plain terms, Eastchester is assessing at a fraction of full market value, not at parity with the Village's own numbers next door. The Town's grievance calendar doesn't match the Village's either. Eastchester's 2026 grievance day fell on June 16, four months after the Village's window had already closed.

So a homeowner who wants to challenge an assessment they believe is too high has to track two separate deadlines, file with two separate boards, and understand that winning one grievance does nothing to the other bill.

The village and school portion of a Bronxville tax bill is reset to market value every year. The county, town, and fire portion is not reset on the same schedule, and can sit well below it for years at a time.

Why the gap shows up on specific streets

This isn't a hypothetical spread. A Tax Watch investigation into the Bronxville and Eastchester rolls found 259 Bronxville homes, about 20 percent of the village's residential parcels, carrying Eastchester assessments at least $537,000 lower than their Village-assessed values, adding up to roughly $270 million in property that goes untaxed for county, town, and fire district purposes. Eighty-eight homes showed a gap of at least $1 million between the two numbers. The investigation traced 74 of the most under-assessed properties to four streets in particular: Park Avenue, Tanglewylde Road, Summit Avenue, and Prescott Avenue.

Those are not obscure corners of the village. They are some of the most sought-after addresses in it. A house on one of those streets can be carrying a Village assessment that reflects this year's market and an Eastchester assessment that reflects a much older one, and the difference never shows up as a line item anywhere. It just shows up as a smaller county, town, and fire tax bill than a comparable house a few blocks away would have.

What this means at the negotiating table

If you're comparing two homes on the market this fall, the combined tax line in each listing tells you what the current owner pays. It does not tell you how much of that number is anchored to this year's value and how much is riding on a valuation the Town hasn't revisited in some time. Two houses with nearly identical Village assessments can carry different total bills purely because their Eastchester numbers were last touched in different years.

For a seller, that cuts both ways. If your Eastchester assessment is meaningfully behind your Village number, your buyer inherits a tax bill that looks lower than the house's true value would suggest, at least for the county, town, and fire portion. That can be a genuine selling point worth mentioning to a buyer's attorney doing due diligence, though it is not something either roll is required to flag for you. If your Eastchester assessment happens to already be close to market, you don't have that cushion, and it's worth knowing before you set an asking price that assumes your tax bill looks like your neighbor's.

For a buyer, the practical step is simple: ask for both assessment numbers, not just the combined bill. A house on Park Avenue, Tanglewylde Road, Summit Avenue, or Prescott Avenue, the streets the Tax Watch investigation flagged most often, is exactly where this gap is most likely to be material.

Two calendars, one missed deadline

The grievance mismatch matters beyond curiosity. If you believe your Village assessment is too high, you have a fixed, narrow window: file by the third Tuesday in February or wait a full year. If you believe your Eastchester assessment for county, town, or fire purposes is too high, that grievance goes through an entirely separate process on Eastchester's own calendar, which fell in mid-June for 2026.

An owner who assumes one grievance covers the whole bill can easily miss the second window without realizing there was a second window to miss. If you're planning to grieve either assessment, mark both dates the moment the year turns over, because the Village's roll appears on February 1 and Eastchester's on its own separate timeline.

Where this sits inside a market that isn't slowing down

None of this happens in a vacant market. Bronxville's Village submarket closed the second quarter of 2026 with inventory arriving in April, thinning by June, and prices holding firm well above Westchester County norms, with single-family closings up nearly 30 percent year to date over the same period in 2025. The current median effective property tax rate across Bronxville sits at about 1.37 percent, producing a median annual bill in the neighborhood of $10,759 as of an April 2026 estimate. That's the backdrop against which two different assessors are quietly producing two different halves of every bill in the village. In a market this tight, a buyer who understands which half of their future tax bill is fixed to market value and which half might still be catching up is negotiating with information most people at the table don't have.

A few questions worth asking directly

Do I need to file two grievances if I think my assessment is too high? Yes, if you want to challenge both halves of the bill. A grievance filed with the Village Assessor only affects the village and school portion. Challenging the county, town, or fire portion requires a separate filing with the Town of Eastchester's Board of Assessment Review, on its own deadline.

Which portion of my bill is larger? The village and school taxes, assessed by the Village at full market value, typically make up about 80 percent of the total. The county, town, and fire taxes assessed by Eastchester make up the remaining 20 percent.

Does living on a certain street mean I'm getting a bigger break? The Tax Watch investigation found the largest gaps between Village and Eastchester assessments concentrated on Park Avenue, Tanglewylde Road, Summit Avenue, and Prescott Avenue. That gap only touches the county, town, and fire portion. The village and school portion stays tied to current market value regardless of address.

Pricing a Bronxville Village home, or evaluating one, means reading past the single number on the bill and understanding which government produced which half of it. That is the kind of detail that belongs in a pricing conversation before an offer goes in, not after.
