Lewis County Property Tax Grievance, New York

Travis BunnTravis Bunn·Updated July 22, 2026

Lewis County is located in northwestern New York between the Adirondack Mountains and Tug Hill Plateau in the state's North Country region. With a 2026 population estimated at 26,446, it is the fourth-least populous county in New York. The median home value in Lewis County is approximately $128,800, significantly lower than New York's state median. However, the effective property tax rate of 1.93% is substantially higher than the national median of 1.02%, making property tax grievances particularly important for homeowners seeking relief from the elevated tax burden. The median annual property tax bill of $2,519 exceeds the national median of $2,400, reflecting the impact of higher rates on relatively affordable housing stock.

How Lewis County Assesses Property

100%of market value

Assessed by: Lewis County Office of Real Property Tax Services and local town assessors

Assessment cycle: annual

Notices typically mailed: Spring (typically mid-May)

New York assesses residential property at 100% of market value, meaning your assessed value should equal your home's full market value. For example, if your home's market value is $128,800 (the county median), at New York's 100% assessment ratio your assessed value would be $128,800, resulting in approximately $2,486 in annual taxes at the county's effective rate of 1.93%. If your assessment is higher than your actual market value, you should file a grievance to correct the overassessment.

The Grievance Process

Appeals are heard by the Board of Assessment Review. The Board of Assessment Review consists of three to five members appointed by the town board. The assessor is required to attend all formal hearings but cannot be a BAR member. You have the right to attend the hearing personally or with your attorney to present statements and documentation supporting your grievance.

1

Step 1: Obtain the tentative assessment roll from your local assessor's office (typically published in early May) to verify your property's assessed value for the current year.

2

Step 2: Research comparable property sales in your neighborhood from the past 6-12 months to establish your home's actual market value. Gather evidence such as recent sales data, photographs of property condition, and repair estimates if applicable.

3

Step 3: Complete Form RP-524 (Complaint on Real Property Assessment) with your property information, desired assessed value, and supporting evidence. You can represent yourself or authorize an attorney or representative to appear on your behalf.

4

Step 4: File your completed RP-524 form and all supporting documentation with your local assessor or Board of Assessment Review on or before Grievance Day (typically May 26, 2026). Keep copies of all submitted materials.

5

Step 5: Prior to the hearing, you may enter into an informal stipulation with the assessor for a reduced assessment by completing Part Six of Form RP-524. If no stipulation is reached, attend the Board of Assessment Review formal hearing to present your case.

6

Step 6: The Board of Assessment Review (BAR) will review your grievance and issue a written determination. If you disagree with the BAR's decision, you can pursue judicial review through Small Claims Assessment Review (SCAR) under RPTL §730 for residential properties (1-3 family homes) by filing within 30 days of the final assessment roll.

7

Step 7: If SCAR does not resolve your grievance, you may appeal to New York State Supreme Court through an Article 7 proceeding for further review of your property assessment.

This is the deadline to file Form RP-524 with your local Board of Assessment Review or assessor's office. However, some villages that prepare separate assessment rolls may have different dates. You should confirm your specific municipality's Grievance Day by contacting your local town assessor or the Lewis County Office of Real Property Tax Services at 315-376-5336. Missing this deadline means you cannot grieve your assessment until the following year.
How do I file a property tax grievance in Lewis County?
To file a property tax grievance in Lewis County, you must complete Form RP-524 (Complaint on Real Property Assessment) available from the NYS Tax Department website or your local assessor. Gather supporting evidence such as recent comparable sales, photos of your property, and any documentation of defects or damage. Submit the completed form along with all evidence to your local town assessor or Board of Assessment Review by Grievance Day (typically May 26, 2026). You can file in person at the Lewis County Office of Real Property Tax Services at 7660 N State St, Lowville, NY 13367 (hours 8:30 AM-4:30 PM weekdays), by mail (must be received by deadline), or check with your local assessor about online filing options.
What is the Enhanced STAR exemption worth in Lewis County?
The Enhanced STAR exemption in Lewis County provides significant school tax savings for eligible seniors aged 65 and older. Based on 2025 data, Enhanced STAR savings ranged from approximately $482 to $1,155 annually depending on your school district and municipality within Lewis County. The exemption removes at least $50,000 from your home's school taxable assessment. To qualify for 2026/2027, your combined household income (all owners and resident spouses) must be $110,750 or less based on your 2024 income tax return, and at least one owner must be 65 by December 31. You must apply with your local assessor by March 1.
What happens at a Board of Assessment Review hearing in Lewis County?
At a Lewis County Board of Assessment Review (BAR) hearing, you will present your case explaining why you believe your property assessment is too high. The BAR consists of three to five appointed members who act independently of the assessor's office. The assessor is required to attend and has the right to be heard on your complaint. You can appear personally or have an attorney or representative speak on your behalf. You should bring all evidence supporting your grievance, including comparable sales data, photos, and any documentation of property defects. The BAR will review your evidence and issue a written determination explaining their decision to reduce, maintain, or adjust your assessment.
How much can I save by grieving my property taxes in Lewis County?
Savings from grieving your property taxes in Lewis County depend on how much your assessment is reduced. With a median home value of $128,800 and an effective tax rate of 1.93%, every $10,000 reduction in your assessed value saves approximately $193 per year in property taxes. For example, if your home is assessed at $140,000 but comparable sales show it's worth only $125,000, a successful grievance reducing your assessment by $15,000 would save you about $290 annually. These savings compound year after year until the next revaluation. Given Lewis County's tax rate is nearly double the national average at 1.93% versus 1.02%, correcting even modest overassessments can yield meaningful long-term savings.
What evidence do I need for a Lewis County property tax grievance?
For a successful Lewis County property tax grievance, you need compelling evidence that your assessment exceeds your property's market value. The strongest evidence is recent comparable sales (past 6-12 months) of similar properties in your neighborhood that sold for less than your assessed value. You should also include clear photographs documenting your property's condition, any defects, deferred maintenance, or damage. Additional supporting evidence can include a professional appraisal report, contractor estimates for needed repairs, documentation of negative factors like road noise or environmental issues, and property characteristic details. Submit at least three copies of Form RP-524 and all evidence, one for the assessor, one for the Board of Assessment Review, and one for your records.
Can I grieve my assessment if I just bought my home in Lewis County?
Yes, you can grieve your property assessment in Lewis County even if you recently purchased your home. In fact, a recent purchase price below your assessed value is strong evidence of overassessment. If you bought your home for $120,000 but it's assessed at $135,000, your purchase contract and closing documents demonstrate the actual market value. You must file Form RP-524 by Grievance Day (typically May 26, 2026) regardless of when you purchased. However, note that you can only grieve the assessment on the current tentative roll, you cannot go back and grieve prior years. Recent buyers should review their first assessment notice carefully and act promptly if the assessed value exceeds their purchase price.
Does Lewis County offer any property tax exemptions for seniors beyond Enhanced STAR?
Yes, Lewis County seniors can benefit from multiple exemptions simultaneously. Beyond Enhanced STAR (which reduces school taxes), eligible seniors can apply for the Senior Citizens Exemption under Real Property Tax Law Section 467, which can reduce your home's assessed value by up to 50% for county, town, and school taxes. Income limits vary by municipality but are typically around $58,399 for the maximum 50% exemption. These exemptions stack, you can receive both Enhanced STAR and the Senior Citizens Exemption. For a senior with a $130,000 home receiving both maximum benefits, total annual savings could exceed $2,000 depending on your local tax rates. Applications must be filed with your local assessor by March 1 annually, and you must be 65 or older.
