2026 Past In-Person Support & Information Sessions
Two large‑group Public Information Sessions were held to explain the revaluation process, why it occurred, the timeline, and what residents could expect. These sessions focused on shared information and general questions, and no registration was required. You can watch recordings of both sessions on the Town of Perinton YouTube channel.
Four Office Hour Sessions were held throughout February. These smaller, informal meetings gave residents the opportunity to speak individually or in small groups with Town officials, ask more specific questions, and learn more about the revaluation in a conversational setting.

What You Need to Know:
The Town of Perinton has initiated a townwide Property Revaluation, a process started in 2025, to update property values and align assessments with the current real estate market. Revaluation does not increase the total amount of taxes collected by the Town. It ensures property assessments reflect current market conditions, as required by state law.
- What is Revaluation?
A townwide property revaluation is a process in which all properties within the Town of Perinton are reviewed and updated to reflect current market value. Property assessments are used to determine how the total property tax levy is distributed among property owners. Think of the tax levy as a pie. The size of the pie is determined by the budgets adopted by the Town, school districts, village, county, and special districts. The Assessor does not determine the size of the pie. - Why is it Happening?
The last townwide assessment update in Perinton was completed in 2018. Since then, the local real estate market has changed significantly, and the Town’s equalization rate (a measure of how closely assessed values reflect current market value) has declined from 100% to 57%. Recent sales data show that property values have shifted unevenly across neighborhoods and property types. The process to begin this revaluation started in 2025. New York State law requires that properties within a municipality be assessed at a uniform percentage of value. Conducting a townwide revaluation helps restore alignment between market values and assessments, improves transparency, and supports a fair distribution of all property taxes. - Does it Mean Higher Taxes?
Not necessarily. Your tax bill depends on your property value and the tax rate. Some bills will go up, some down, some stay the same. A townwide property revaluation updates property assessments so they more accurately reflect current market conditions. These assessments are used to determine how the total tax levy is distributed among property owners, not how much revenue the Town collects overall. Each year, the Town establishes a tax levy, which is the total dollar amount needed to fund municipal services. That levy is set through the budget process and is not determined by individual property values. The tax rate is calculated by dividing the tax levy by the total taxable assessed value of all properties in the Town. When assessed values are updated townwide, the tax rate adjusts accordingly to account for changes in the overall tax base.

Think of the tax levy as a pie. The size of the pie is determined by the budgets adopted by the Town, school districts, county, and special districts. The Assessor does not determine the size of the pie.
The Assessor’s role is to ensure the pie is divided fairly. When real estate markets change and assessments are not updated, some properties may be assigned slices that are too large, while others receive slices that are too small. Over time, this can cause some property owners to pay more, while others pay less.
A townwide property revaluation updates assessments so the pie is sliced according to current market values. By assessing all properties at a uniform percentage of market value, the revaluation helps ensure the tax burden is distributed equitably across the community.

This update allows the Town to:
-Ensure property taxes are distributed based on current market values
-Improve consistency in how the tax burden is allocated across properties
-Align assessments with New York State assessment standards
-Help avoid situations where some property owners pay more than necessary while others pay less due to outdated assessments
This update does not:
- Set tax rates
- Increase the total amount of taxes collected by the Town
- Determine school, county, village or special district taxes
The Assessor’s Office does not determine taxes. Property taxes are based on the estimated market value of the property minus any applicable property tax exemptions. A tax rate is calculated by dividing the taxing jurisdiction’s budgeted tax levy by the taxing jurisdiction’s total taxable assessment:
Budgeted Tax Levy
_________________ = Tax Rate per Dollar of Assessment
Taxable Assessment
Multiplying the above tax rate per dollar by 1,000 will result in the tax rate per thousand dollars of assessment, which appears on most tax bills.
- A revaluation does not increase the total taxes collected by the Town.
- It updates assessed values so taxes are distributed more evenly among properties.
- The tax rate is recalculated automatically after a revaluation. When total property values increase townwide, the rate generally decreases because the Town is collecting the same amount of money overall.

Notification of proposed assessment changes were mailed in March 2026.
If you disagree with the your revaluation, you may request an informal review. An informal review is an opportunity for property owners to share information with the Town Assessment Office if they believe their preliminary assessment does not reflect current market value. If you agree with your preliminary assessment, no action is required.
What Is an Informal Review?
An informal review allows property owners to submit information they believe should be considered when estimating the market value of their property. Informal reviews focus only on market value, not tax rates or tax bills.
When Should You Request a Review?
You may wish to request an informal review if, after reviewing your preliminary assessment and comparing it with recent property sales, you believe relevant information about your property has not been fully considered.
How to Prepare
Before requesting an informal review, property owners are encouraged to gather and review information that helps establish current market value, such as:
- Recent sale prices of similar properties
- A recent sale or listing of your property
- A recent appraisal (not prepared for a mortgage transaction)
- Documentation of property conditions or characteristics that may affect value
- Photographs or other supporting information
How to Request an Informal Review
Property owners may submit information in one of the following ways:
1. By Email: Send documentation to 2026Update@perinton.gov using the subject line: Informal Review. Please include your parcel ID number and property address.
2. By Mail: Send written information to: Town of Perinton Assessor’s Office, 1350 Turk Hill Road, Fairport, NY 14450
