Is Your Binghamton
Property Assessment
Excessive?

Binghamton's assessment roll runs from Downtown and the West Side to the First Ward and the riverfront — a Southern Tier city at the confluence of the Susquehanna and Chenango. Many owners carry assessments that don't reflect actual market conditions or property condition.

An assessment is an opinion, not a final number. Duffy & Catlin PLLC represents commercial, industrial, and residential owners across Binghamton and Broome County in challenging assessments that don't hold up — at no upfront cost.

Why Binghamton Owners Are Seeing Increases

How Binghamton Values Your Property — and Where It Goes Wrong

When City of Binghamton builds its assessment roll, properties are valued in bulk using broad market models. Those models lean on neighborhood-wide trends — not your building's condition, your block, your actual rent roll, or the most relevant comparable sales.

Binghamton's economy is anchored by Binghamton University, healthcare, and a manufacturing heritage that traces back to IBM's founding here. Flood exposure along the rivers, aging commercial stock, and shifting demand all complicate valuation — and mass models rarely capture them. New York law lets you challenge an excessive assessment, but only within the window set by the city's charter.

  • Income-producing properties have distinct valuation standards the assessor is required to apply
  • Vacancy, below-market leases, and deferred maintenance are all recognized grounds for challenge
  • Older and industrial properties often carry functional obsolescence that mass models overlook
  • You are not required to accept the city's opinion of value as final

Who We Represent in Binghamton

Commercial, Industrial & Residential Challenges Across the City

Commercial and industrial properties are especially vulnerable to over-assessment in a mass revaluation. The income, cost, and sales-comparison approaches each require proper application — and a mass model doesn't always get Binghamton right.

🏢

Commercial & Office

Downtown office, Court Street retail, and mixed-use are frequently assessed without proper regard for real vacancy, lease terms, or market income. We apply the correct methodology to challenge inflated values.

Downtown office Court Street Mixed-use Storefronts

Industrial & Warehouse

Manufacturing, warehouses, flex space, and riverfront industrial carry functional obsolescence, flood exposure, and thin comparable sales that mass appraisals routinely miss.

Manufacturing Warehouses Flex space Riverfront industrial

Residential & Multi-Family

Homes, doubles, and student rentals across the West Side, First Ward, and South Side all benefit from review. Even modest increases compound into real tax liability over an assessment cycle.

Single-family Doubles Student rentals Multi-family
Hidden Tax Increases

Even a Flat Assessment Can Cost You More

New York calculates an equalization rate for every municipality — the ratio of assessed value to full market value. When Binghamton and Broome County market prices rise faster than assessments are updated, that rate falls, and the State treats your property as worth more for purposes of county tax apportionment.

The result is a larger share of the Broome County levy landing on your bill — with no change to the assessment roll and no formal notice. If your assessment was already excessive, the compounding effect is even greater. A timely challenge corrects both problems at once.

How a Binghamton Challenge Works

Step 1

Free Case Review

Send us your assessment notice. We evaluate whether your Binghamton property has been over-assessed and advise you honestly on the strength of a challenge — at no cost and no obligation.

Act Early
Step 2

Informal Review

Binghamton's assessor often allows a brief period to engage before the formal deadline. Early contact gives us the most time to build a complete, well-supported case.

Hard Deadline
Step 3

File With the City BAR

We file your grievance with the Binghamton Board of Assessment Review before its charter deadline. Binghamton's date differs from the town Grievance Day — we track the correct one for your property.

Step 4

Hearing & Tax Relief

We represent you at every hearing. Approved reductions appear on your school tax bill in late summer and your Broome County bill issued the following January.

Common Questions

Binghamton Property Owners Ask

When is the deadline to challenge my City of Binghamton assessment? +
The City of Binghamton operates under its own charter and sets an assessment grievance deadline that is independent of — and often earlier than — the standard town Grievance Day on the 4th Tuesday in May. Because the date can shift and is unforgiving once passed, the safest step is to contact us as soon as you receive your assessment notice so we can confirm the current deadline for your property and file in time.
If my assessment went up, does that mean my taxes are going up? +
A higher assessed value doesn't automatically raise your bill — it depends on your assessment relative to other Binghamton properties and the applicable tax rates. But a significantly elevated value can translate into a real increase in city, county, and school taxes, especially for commercial and industrial property. We can review your specific notice and explain what it means for you.
Do you handle properties outside City of Binghamton? +
Yes. We represent owners throughout Broome County — Vestal, Johnson City, Endicott and beyond — and across all of New York State. Town properties follow the standard Grievance Day schedule, while cities use their own charter deadlines. We track the correct one for your municipality.
What does it cost to have Duffy & Catlin PLLC challenge my assessment? +
Nothing upfront. We work on a contingency basis — we only collect a fee if we achieve a reduction in your assessment. The initial consultation and case review are always free. There is no financial risk in having us evaluate your Binghamton property.
What makes commercial challenges different from residential ones? +
Commercial valuation is considerably more involved. Income-producing properties are typically valued using an income-capitalization approach that accounts for vacancy, actual rents, operating expenses, and market cap rates. Mass reassessments frequently fail to apply these factors correctly, which is why commercial challenges often have strong evidentiary grounds.
What if my case isn't strong enough to challenge? +
We'll tell you that upfront — at no cost. We only pursue challenges where the evidence supports a meritorious case. Our credibility with the Binghamton assessor and the Board of Assessment Review depends on bringing well-grounded, properly documented appeals.
How long does the process take? +
The informal review and Board of Assessment Review process typically runs through spring and early summer. Cases that proceed to SCAR or Article 7 court proceedings may take additional months. Throughout, our attorneys handle all communications and appearances on your behalf.
