2020 Town Wide Reassessment Project

Please check back to this page as well as the Town's website (Click Here) regularly for the most current information regarding this reassessment project.

The Town of Rye is committed to providing fair and equitable assessments in each annual assessment roll so that property owners pay only their fair share of property taxes. The last town-wide assessment revaluation took place in 2011. The Town Board approved the request to perform a town-wide reassessment/revaluation for the 2020 assessment roll for the 2021 taxes. The Town has contracted with Tyler Technologies (Contractor) to perform this reassessment project.

Accurate property inventory/information is vital to an equitable assessment. Commencing in 2019 and continuing today, the Contractor has been reviewing and collecting information on your property. As the Contractor updates your property data, it will become available through this web portal for you to review.  You will first be sent a data mailer by the Contractor that will list the details of your property.  You will have the opportunity to mark up the hard copy and return it by regular mail, or even better, you can access your property here and make these changes online (see Inventory Change Request button).    We ask that you confirm the information on your property and make any changes in the areas provided. This updated information will enable us to compare and review the market values of all of the properties in our community and then based on the current real estate market, determine fair and equitable assessments.  Some change requests may require an inspection of your property.

In the future, we encourage you to use this Inventory Change Request tool regularly to verify your data and inform the Contractor of any discrepancies you might find.
