Description: Tax parcels in all 62 New York counties from the 2025 assessment rolls, as published by NYS Geospatial Services in its Statewide Tax Parcel Centroid Points file (publication date May 2026; downloaded Nov. 5, 2026). Attribute values come from the assessment roll data of the NYS Department of Taxation and Finance's Office of Real Property Tax Services; New York City parcels come from NYC MapPLUTO and have no owner mailing address. The data has 5,510,061 parcels. The earlier edition, from the 2017 rolls, is the dataset New York Properties 2017.
Each record is one owner of a parcel: the primary owner, and, where the roll lists one, an additional owner in a second record. A record has the parcel's county, municipality, address, property class, assessed and full market values, size, building details, school district, deed book and page, parcel IDs, and the owner's name and mailing address. A data dictionary describes every column. The full data files contain all original columns. Data processing was done using open-source software and is documented on the Accountability Project GitHub repository.
