How Wyoming County Assesses Property

100%of market value

Assessed by: Wyoming County Real Property Tax Services

Assessment cycle: annual

Notices typically mailed: Spring (typically by mid-May)

Wyoming County assesses property at 100% of market value, though actual assessment practices may vary by town. In New York, properties are nominally assessed at full market value with equalization rates applied to normalize across municipalities. If your home's market value is $150,500 (the county median), at the 100% assessment ratio your assessed value would be $150,500, resulting in approximately $3,785 in annual taxes at the county's effective rate of 2.38%.

The Grievance Process

Appeals are heard by the Board of Assessment Review. The Board of Assessment Review consists of 3-5 appointed members who will review your grievance application and supporting evidence. You have the right to appear at the hearing and present your case, or the board may review your written submission. The assessor will also attend and may present counter-evidence.

1

Step 1: Obtain the Tentative Assessment Roll from your town assessor when it's published (typically by May 1st) to review your property's assessed value.

2

Step 2: Research comparable property sales in your area from the past 6-12 months to determine if your assessment is too high. Gather evidence including recent sales data, photographs of your property showing condition issues, and repair estimates for any defects.

3

Step 3: Consider scheduling an informal review with your town assessor before Grievance Day to discuss your concerns. Many disputes are resolved at this stage through stipulated agreements.

4

Step 4: Complete Form RP-524 (Complaint on Real Property Assessment), available at tax.ny.gov, including your property information, estimated market value, and grounds for your grievance (overvaluation, unequal assessment, or unlawful assessment).

5

Step 5: File your completed RP-524 form with supporting documentation to the Board of Assessment Review before the close of Grievance Day. You may attend the BAR hearing to present your case in person, or submit your evidence in writing.

6

Step 6: If the Board of Assessment Review denies your grievance or you're unsatisfied with the result, you can file a Small Claims Assessment Review (SCAR) petition in New York State Supreme Court within 30 days of the final assessment roll (typically due in July), or file an Article 7 proceeding for larger commercial properties.

7

Step 7: For residential properties valued under approximately $500,000, SCAR provides an expedited, lower-cost judicial review option with a $30 filing fee, representing your final opportunity to challenge the assessment for that tax year.

Frequently Asked Questions

What is the deadline to file a property tax grievance in Wyoming County?
The grievance deadline in Wyoming County varies by town but falls between the fourth Tuesday in May (May 26, 2026 for most towns) and the second Monday in June. Each town sets its own Grievance Day when the Board of Assessment Review meets to hear complaints. You must file Form RP-524 with the Board of Assessment Review before the close of the Grievance Day session. It's critical to contact your specific town assessor or call Wyoming County Real Property Tax Services at 585-786-8828 to confirm your exact deadline, as missing Grievance Day means you cannot appeal your assessment until the following year.
How do I file a property tax grievance in Wyoming County?
To file a grievance in Wyoming County, first obtain the Tentative Assessment Roll when it's published around May 1st to review your assessment. Complete Form RP-524 (Complaint on Real Property Assessment), available from the NYS Tax Department website at tax.ny.gov. Include supporting evidence such as recent comparable sales, photographs showing property condition, and repair estimates. File the completed form with your town's Board of Assessment Review before Grievance Day, either in person at 143 N Main Street, Warsaw, NY 14569, or by mail (must be received, not just postmarked, by the deadline). You may also schedule an informal review with your assessor before filing to potentially resolve the dispute through a stipulated agreement.
What property tax exemptions are available in Wyoming County?
Wyoming County homeowners can apply for several exemptions including the Basic STAR exemption (available to all primary residence owners with income under $500,000), Enhanced STAR for seniors 65+ with income under $110,750 (providing $1,000-$3,000 in annual savings), the Senior Citizens Exemption under RPTL §467 which reduces assessed value by 5% to 50% based on income, Veterans Exemptions for qualifying wartime veterans, and a Volunteer Firefighters/Ambulance Workers Exemption worth 10% of assessed value up to $3,000. Most exemption applications must be filed with your town assessor by the March 1st deadline each year. These exemptions can be combined in some cases to provide substantial tax relief.
What happens if I miss the grievance deadline in Wyoming County?
Missing the grievance deadline in Wyoming County means you lose your right to challenge your property assessment for that entire tax year, with no exceptions or extensions granted. New York's grievance system is strictly enforced - even if your property is clearly overvalued, you must wait until the following year's Grievance Day to file a complaint. This is why it's critical to mark your calendar and confirm your town's specific Grievance Day well in advance by calling 585-786-8828. If you mail your grievance form, it must be received by the Board of Assessment Review by Grievance Day; postmarks do not count. Being one day late means waiting a full year and paying the higher taxes in the meantime.
How much can I save by grieving my property taxes in Wyoming County?
The potential savings from a successful property tax grievance in Wyoming County depends on how much your assessment is reduced and the county's effective tax rate of 2.38%. For example, if your home is overassessed by $20,000 and you successfully reduce the assessed value, you would save approximately $476 annually ($20,000 × 2.38%). If your assessment is reduced by $50,000, you could save about $1,190 per year. Given that Wyoming County's median annual tax bill is $3,785, even a 10-15% assessment reduction could save homeowners $378-$568 annually. These savings compound year after year, making a successful grievance worth thousands of dollars over time. However, success depends on presenting strong evidence that your property is overvalued compared to recent comparable sales.
What evidence do I need for a successful property tax grievance in Wyoming County?
For a successful grievance in Wyoming County, you need compelling evidence that your property is overvalued. The most important evidence is recent comparable sales - properties similar to yours in size, age, condition, and location that sold within the past 6-12 months for less than your assessed value. Include at least 3-5 comparable sales with addresses and sale prices. Also provide photographs documenting your property's condition, any defects, or features that reduce value. Contractor estimates or repair quotes for needed work strengthen your case. If available, include a recent professional appraisal. You can also present evidence of assessment inequality by showing that similar properties in your town have lower assessed values per square foot. The Board of Assessment Review weighs all evidence, but recent arm's-length sales carry the most weight.
Can I grieve my property taxes if I just bought my home in Wyoming County?
Yes, you can grieve your property taxes in Wyoming County even if you recently purchased your home, and your recent purchase price can actually serve as strong evidence of market value. If you bought your home in an arm's-length transaction (not from a family member or in a foreclosure) within the past year or two, and the assessed value is higher than what you paid, this is compelling evidence your assessment is too high. Include your closing statement and deed as evidence when you file Form RP-524. However, you must still meet the Grievance Day deadline and follow all filing procedures. Your recent purchase price is particularly persuasive evidence because it represents what a willing buyer actually paid a willing seller in the open market, which is the definition of fair market value used in New York property tax assessments.
What is the difference between assessed value and market value in Wyoming County?
In Wyoming County, properties are assessed at 100% of market value, meaning your assessed value should theoretically equal what your property would sell for on the open market. However, because reassessments don't occur every year, your assessed value may not keep pace with changing market conditions, leading to overassessments when property values decline or underassessments in rapidly appreciating markets. New York applies equalization rates to normalize assessments across municipalities with different assessment practices. When you file a grievance, you're arguing that your assessed value exceeds your property's true market value as of the valuation date (typically July 1 of the prior year). Your annual property tax bill is calculated by multiplying your assessed value by the combined tax rates for county, town, school district, and any special districts.
