The property tax season in New York starts in earnest when tentative assessment rolls are released. These are the previews of how property across a county will be valued in 2027. Since these assessments act as the basis for tax bills, they are of vital importance for businesses, homeowners, and other real estate owners. With property values and taxes in NYC, Long Island, and the surrounding area being some of the highest in the world, knowing what a tax bill could be in the future is of dire importance.
Now that tax appeals and grievances have generally been settled, it is time for final rolls across the state to be released. July sees the final rolls for most of the state, while New York City and a few other municipalities have already seen their final rolls. Real estate owners across the Empire State should review these rolls, as they will be an excellent preview of what taxes will look like in the near future.
What is the Final Assessment Roll?
After grievances have been filed, reviewed, and approved by various county boards, changes are made to the tentative rolls. These take into account the changes made to property values thanks to grievances and appeals, giving a more accurate measure of the county’s property values. Once these values are confirmed, the final roll is published, giving a permanent record of how each property in the county is assessed.
The final roll is a wealth of information. It includes not only the market and assessed values of real estate, but all vital information as well. This includes exemptions, square footage, the number of rooms, classification, improvements, and more. This will act as a reference point for both taxpayers and taxing bodies, which will use this data to craft property tax bills after applying tax rates and subtracting exemptions.
Final Assessment Roll Dates
Just like tentative rolls and grievance deadlines, the dates for when final assessment rolls are published can vary wildly depending on the county. As a rule of thumb, the earlier a tentative roll becomes available, the earlier the final roll will be published. For instance, since Nassau County typically posts its tentative roll and goes through the grievance process first, it usually has the first final roll, typically filed on April 1. The easiest way to see your roll is to visit your town or county’s website, which will have the release date and an entire copy of the roll on file.
Notable final roll publication dates:
- The majority of the state: July 1
- New York City: May 15
- Nassau County: April 1
- Most of Westchester County: August 1
- Westchester County municipalities may publish final rolls on different dates depending on the locality.
When do Assessment Changes Take Effect?
While grievances and other assessment matters are being taken care of in 2026, the impact of these changes will not be felt until 2027. This is because property taxes use the values of the previous year. For instance, this year’s taxes are based on values confirmed in 2025. This means that the values on the final assessment roll will be used for tax bills released next year. This makes managing property taxes in New York an all-year affair, and is why it is so important to always stay informed.
How the Final Roll Impacts Escrow Accounts and Mortgages
Final assessment rolls represent a total reassessment of your property, which can have an impact on your property’s value. While this will be felt in taxes, it bleeds into your mortgage and its escrow account. In most mortgages, property taxes are figured into your monthly payment. Your lender will analyze the new property values and adjust the payment amount to match the forecasted taxes. A large increase in value will surely lead to an eventual increase in your monthly payment as well. This is why you should review your final roll, so you can budget for larger payments that will come due in the near future. Obviously, a successful grievance can have the opposite effect.
STAR and Other Exemptions
The assessment roll will also contain information on your exemptions, most notably the School Tax Relief Program (STAR). School taxes are the largest type of property levy in New York, and STAR helps lower them every year. For most homeowners, this comes in the form of payments to offset taxes, though older homeowners may instead get this relief as an exemption applied directly to bills. Seniors can also qualify for Enhanced STAR, which provides even larger savings.
It is important to verify that all exemptions are applied to your property. Your exemptions will appear on your final roll or can be checked through your assessor’s website. If you missed the exemption filing deadline or will qualify for a new exemption in the coming year, you will need to file by the deadline, which is typically in March. Retroactively applying exemptions is generally difficult under current New York law. However, there is currently a bill in the New York Senate that would allow for a second chance, which has seen widespread support.
The Importance of Grievances and Appeals
While the grievance deadline has passed for the majority of the state, the year-round nature of the property tax cycle in New York should always keep them at the forefront of your mind. Property taxes in the state continue to increase, for both homes and businesses. Grievances, also known as appeals in New York City, are a legal way to challenge the market value of properties. They do not affect the resale value of a piece of real estate, rather they only challenge inflated values, possibly leading to a substantial tax reduction. They can also fix errors present on the tentative assessment roll before they become permanent. This is why all taxpayers should be cognizant of when their tentative roll becomes available and when their grievance deadline is.
