Elmira's tax base has barely grown in five years. Nearly 40% of the city's
property pays no taxes at all. And the values on the ones that do pay haven't
been seriously updated in decades. Here is what that means — and why it happened.
The Simple Version
Three problems. Here is each one in plain terms.
Problem 1 — The city guesses low on what homes are worth.
Every year, Elmira charges property taxes based on what it thinks your house
is worth. But those estimates haven't been seriously updated in decades.
Homes that are selling for $130,000 are still taxed as if they're worth $55,000.
That means the city is collecting far less than it could — and the gap grows
every year that prices rise and the estimates don't.
Problem 2 — Nearly 40% of the city's property pays nothing.
Hospitals, colleges, churches, and government buildings don't pay property tax.
That's the law. In Elmira, those properties make up almost 40 cents of every
dollar of property value in the city. The remaining 60 cents has to cover
the full cost of city services — for everyone, including the tax-exempt properties
that use those same services. Scroll to the 3D map just below and look at the
blue: every blue parcel is one of these.
Problem 3 — The frozen system taxes the cheapest homes the hardest.
When a home sells, we can compare its assessment to what a buyer actually paid.
Across 1,689 real city sales, homes selling under $40,000 — concentrated in the
city's poorest neighborhoods — are assessed at 130% of their sale price: their
owners pay tax on value that doesn't exist. Meanwhile an Elmira home selling for
$130–175K is assessed at just 42% of its price. Per dollar of real value, the
cheapest homes carry roughly twice the tax of the most expensive.
The City in 3D: Value per Acre, Parcel by Parcel
All three problems, on one map. Every City of Elmira parcel on its actual
footprint, extruded into a 3D bar — height is assessed value per acre, color runs
red (least productive) to green (most), and blue marks the fully tax-exempt
parcels from Problem 2. Because the whole city shares one frozen roll, these
parcels compare fairly with each other; a
county-wide version shows how the frozen roll
makes the city read low next to towns that reassess.

The city has not conducted a mass reassessment in many years.
As a result, assessed values are locked in place while the actual real estate
market has moved significantly.
The median single-family home in Elmira has been assessed at exactly
$47,000 every year from 2021 to 2025. Over the same five years, the
assessor's own estimate of full market value rose from $55,294 to $83,900 — a
52% increase. The assessment didn't move because the city's assessment roll
is effectively frozen until a mass reassessment is ordered.

Is Elmira cheating by assessing low? No — this part is legal, and the state
corrects for it. New York lets every city and town assess at its own level. The
law only requires fairness within each municipality: all Elmira properties should
be assessed at roughly the same fraction of their real value, whatever that fraction is.
For the tax bills that cross town lines — the school and county bills — the state uses
each municipality's equalization rate
to put everyone back on the same footing.
Here is how that works for two identical $150,000 homes, one in Elmira and
one in Horseheads. The Elmira home is assessed at $84,000 (56% of its value); the
Horseheads home at $132,000 (88%). Before the school and county bills are split, the state
divides each assessment by the local rate — $84,000 ÷ 0.56 and $132,000 ÷ 0.88
both come back to $150,000 — so both owners pay the same school and county tax. Different
assessment levels between towns, same bill.
Where the stale roll actually causes harm is inside Elmira itself — and
that, the equalization rate cannot fix, because it is one citywide average. The city's
assessment roll is a patchwork of
whenever each parcel was last formally valued: recent for some properties, decades ago for
others. Even a sale is no guarantee of an update — of 2,354 residential ownership transfers
from 2021–2025, only 44 (1.9%) received any assessment change at all. So two identical
houses on the same street can carry very different assessments simply because one was
touched at some point and the other wasn't. Neighbors end up subsidizing neighbors.
Median Assessed vs. Full Market Value, 2021–2025
Solid = assessed, dashed = full market value. Elmira's assessed line (red) is
flat while its market value climbs; neighboring towns track market value closely.
Why hasn't the city reassessed in so long? Because a stale roll is a political
choice, not an accident. Who the freeze protects, who pays for it, and what a
reassessment would actually take is its own story —

Problem 2: The Exemption Burden
Nearly 39% of the city's assessed value generates no property tax revenue.
That burden falls entirely on the remaining 61%.
$355M in value is off the tax rolls. That is $339.6M fully exempt
across 656 parcels, plus another $15.5M sheltered by partial exemptions. Set the
government property aside and roughly $177M is held by private tax-exempt
institutions: a major hospital system, a college, a medical school, religious
congregations, and a layer of economic-development deals. Public buildings are out of
reach. These are the exemptions a PILOT negotiation could actually touch.

A note on IDA and housing abatements:
On top of the institutional exemptions, at least $34M in apartment buildings is fully
exempt through economic development deals. The Chemung County IDA holds some, the Elmira
Housing Authority holds some, and various non-profit housing developers hold the rest.
Each of those was a deliberate choice, made to attract or protect affordable housing.
They also squeeze the taxable base further. Whether the benefit is worth the forgiven
tax is a fair question to ask.

Problem 3: The Burden Falls Hardest on the Cheapest Homes
Full analysis →
Every sale is a market test of an assessment: compare what the assessor said a
home was worth to what a buyer actually paid. Run that test across thousands of
arm's-length sales and the frozen roll's real inequity appears — it is
regressive.

2.0×Tax burden gap — cheap vs. expensive per dollar of actual market value
The cheapest homes are taxed on value that doesn't exist.
In the city, homes selling under $40,000 — concentrated in the most distressed
neighborhoods — carry a median assessment of 130% of their actual sale price,
while homes selling for $130,000–$175,000 sit at 42%. Per dollar of real value,
the cheapest homes pay roughly twice the tax of the most expensive. And before
any question of direction: the typical Elmira assessment misses the mark by
about half, against an assessment-industry standard of 15%.
The mechanism is the freeze itself. Nothing corrects an assessment when the
market moves: of roughly 2,300 residential ownership transfers in the city from
2021 to 2025, only 44 saw any assessment change at all. Appreciating
neighborhoods drift further below their assessed fraction every year, while
declining blocks stay pinned at values the market abandoned long ago. The
people least able to appeal — and least likely to know they can — are the ones
paying taxes on phantom value.

Putting It Together
The City of Elmira's 0.4% assessment growth over five years isn't a fluke or a
data error. It's the predictable result of three compounding problems:
A frozen assessment roll — the city assesses homes at 56% of their
market value, a ratio that hasn't changed while markets have moved. The tax base
doesn't grow as home values rise because no reassessment is capturing those gains.
A heavy institutional burden — nearly 39% of assessed value is
permanently off the tax rolls, concentrated in a state prison, a hospital system,
and multiple educational institutions. These large properties use city roads,
sewers, water, and fire services but contribute nothing directly to the city's
general fund.
A regressive distribution — because nothing updates assessments
as the market moves, the burden quietly shifts onto the cheapest homes, which
are taxed on value that no longer exists, while higher-value homes drift further
below their true value every year.
None of this fixes itself. What a reassessment would and wouldn't do — who wins,
who pays more, why the freeze persists, and what your own bill might look like —
is its own page: Who the Assessment Freeze
Protects. The tool for the exemption burden is a different one:
PILOT agreements.
