Property Taxes in Pelham / City Island
This is the single most important thing to understand before buying anywhere in this market: City Island and Pelham are taxed under two completely different systems, run by two completely different governments, and the difference is structural, not just a different percentage. This page walks through both in full, separately.
Two Governments, Two Tax Systems -- Why This Isn't One Rate
City Island is part of New York City, in Bronx County, and its property tax runs through the NYC Department of Finance under the city's own four-class property tax system. Pelham is part of Westchester County -- a separate, non-NYC county -- and its property tax runs through the conventional New York State system of stacked town, village, county, and school district levies, administered by the Town of Pelham Assessor's office and collected by the Town of Pelham Receiver of Taxes. These aren't two dialects of the same tax code; they're two different codes entirely, a direct consequence of City Island's 1895-1896 departure from Westchester County (and from the Town of Pelham specifically, which it had been part of since 1819) to join New York City.
A buyer moving from a conventional suburban tax bill to a NYC Class 1 bill, or vice versa, should expect the math itself to work differently, not just the number at the bottom.
City Island: Inside NYC's Class 1 System
New York City taxes real property under four classes. Class 1 covers one-, two-, and three-family homes -- effectively all of City Island's residential housing stock -- and Class 2 covers larger residential buildings, condos, and co-ops. For fiscal year 2026, the NYC Department of Finance's published rates are 19.843% for Class 1, 12.439% for Class 2, 11.108% for Class 3 (utilities), and 10.848% for Class 4 (commercial/industrial). The critical detail: Class 1's rate applies to only 6% of a home's market value under the city's assessment-ratio system, not the full market value, so a headline 19.843% rate does not mean anywhere near 19.843% of a home's actual sale price.
Class 1 also carries real assessment-growth protections: increases in assessed value are capped at 6% per year and 20% over five years, regardless of how much a home's market value rises in that period. That means a City Island owner whose home appreciates sharply in a hot year won't see their assessed value -- and therefore their tax bill -- jump by the same percentage; the increase phases in over multiple years. This page does not calculate a specific projected dollar tax bill for a hypothetical City Island home, since actual assessed value (as determined by the Department of Finance, and which can differ from market value) drives the real number. Look up a specific parcel's current assessment and tax history directly through NYC's own property tax tools.
Pelham: Westchester County's Stacked Levy System
Pelham and Pelham Manor property owners receive a combined bill reflecting several separate taxing authorities layered on top of one another: the Town of Pelham, the relevant village (Village of Pelham or Pelham Manor), Westchester County, and the Pelham school district. There is no citywide class system discounting the assessment base the way NYC's Class 1 does -- Westchester's system assesses property on a more conventional basis, and it's the sum of the separate town, village, county, and school rates that produces the final bill. A reported effective tax rate around 3.42% in the Village of Pelham's 10803 ZIP code reflects that combined structure -- meaningfully higher than the roughly 1.90% New York statewide median effective rate and far above the roughly 1.02% national median, which is a common pattern in high-service, high-school-spending Westchester communities generally, not unique to Pelham.
One real, usable relief mechanism for Pelham owners: New York's STAR (School Tax Relief) program. For the 2025-2026 school year, the Town of Pelham's published STAR exemption amounts are $234,140 for the enhanced exemption (available to qualifying senior homeowners) and $81,580 for the basic exemption -- these are exemption amounts applied against assessed value for school tax purposes, not direct dollar savings, so the actual reduction in a specific tax bill depends on the local school tax rate. Ask the Town of Pelham Assessor's office directly whether a specific property and owner qualify, and what the resulting dollar impact would be.
A Direct Comparison, Handled Carefully
It's tempting to line up NYC's 19.843% Class 1 rate against Pelham's roughly 3.42% effective rate and conclude City Island is dramatically cheaper to own. That comparison is misleading without the assessment-ratio context: NYC's 19.843% applies to only 6% of market value, while Pelham's 3.42% is described as an effective rate against a more conventional assessment basis closer to full value. Run through actual dollars rather than headline rates: a City Island home assessed at $600,000 market value would have its Class 1 tax base calculated on roughly $36,000 of assessed value (6% of $600,000), at 19.843%, producing a materially different bill than 3.42% applied to something closer to $600,000 in Pelham. This page does not run that full calculation as a promised dollar figure for either place, since real assessed values (as determined by the respective assessor's offices) frequently differ from market value in both directions -- but the structural point stands: these are not comparable percentages without adjusting for what each percentage is applied to.
A buyer genuinely comparing a City Island purchase against a Pelham purchase on tax grounds should ask both the NYC Department of Finance and the Town of Pelham Assessor's office for the actual current assessed value and computed annual tax bill on specific comparable properties, rather than comparing headline rates.
What Happens After a Sale: Reassessment Timing
In NYC's system, a property's assessed value does not automatically reset to its sale price the moment a sale closes -- the city's Department of Finance updates assessments annually as part of its own citywide valuation cycle, and Class 1's growth caps continue to apply regardless of the sale. A new City Island owner should not assume their first tax bill will reflect the exact price they just paid.
Westchester's system similarly runs on an annual assessment cycle set by the Town of Pelham Assessor rather than resetting instantly at closing. In both places, a buyer relying on the current owner's tax bill as a preview of their own future bill should confirm directly with the relevant assessor's office how and when a sale typically triggers a reassessment, since the timing and magnitude can differ by market condition and by whether the seller carried any exemptions (like STAR) that won't transfer to a new owner.
What This Page Does Not Know
This page does not have a confirmed current computed dollar tax bill for any specific City Island or Pelham/Pelham Manor property, since that depends entirely on the individual parcel's current assessed value, which this research did not pull for a hypothetical example. It also does not have confirmed data on how frequently NYC reassesses individual City Island Class 1 properties in practice, or a confirmed current combined Westchester tax rate (town + village + county + school, summed) for either Pelham village specifically, beyond the single reported effective-rate figure cited above.
For a specific address, get the actual current assessment and tax bill directly from the NYC Department of Finance (for City Island) or the Town of Pelham Assessor's office and Receiver of Taxes (for Pelham/Pelham Manor) before making a purchase decision.
