What changed when
your town reassessed?
Explore the shift from the 2025 final assessment to the 2026 final assessment. Start with Peru, Beekmantown, Plattsburgh, or the Clinton County side of Keeseville—or choose another municipality.
Keeseville note: The former village spans the Town of Ausable in Clinton County and the Town of Chesterfield in Essex County. This pilot currently covers the Ausable side; Chesterfield properties are not included.
Find your property
Choose a municipality and search a street address. For the five priority municipalities, search both official rolls directly. Other towns use New York State's 2025 data.
Search by street to get started.
Your assessment comparison
Select a matched property to see the official year-over-year change, or enter values manually.
An assessment increase is not the same as a tax-bill increase. This comparison does not establish overassessment or predict taxes. The county's official roll is the source of record.
