The Town of Ossining is about to start the process of conducting a town-wide reassessment program and has awarded the contract to Tyler Technologies. The process will produce fair, full market value of every property in the Town and Villages for the 2016 assessment roll. This will result in an improved understanding of the process, reduce the need for assessments to be appealed over time, and a reduction in property tax refunds. The process is revenue neutral, meaning the purpose is not to increase the total amount of property taxes the town receives.

Please view this Portal frequently as it will keep property owners abreast of the reassessment project’s progress as well as the public meeting schedules and locations.  Informational letters and notification will be send out by Tyler throughout the project and we ask that you pay attention to anything that comes to you. Please help us by providing any information that may be requested so in the end every assessment is as accurate as possible.

Tyler Technologies will begin with the data collection process, then move to valuation, and then to informal to formal appeals.  You will be notified at various stages along the project and there will be opportunities for you to provide input.  In order for this project to be a success, we ask that you participate with us.  Please do not hesitate to contact Tyler Technologies with any questions and or concerns you may have.
