The Digital Tax Map has been republished on Open Data as a growing collection of its map layers and data tables. You can find the collection here with the latest information: Digital Tax Map Collection.

• Updates: Data is extracted from DOF’s internal system on the last Friday of each month and refreshed on ArcGIS Online on the 1st. The online map always shows the most recent version.

• Accessing the Data:
• Digital Tax Map on NYC Open Data: See the complete collection.
• Individual layers: Downloadable from the Digital Tax Map Feature Server.
• Complete source: Available through the Digital Tax Map service, which always points to the latest monthly release.

Note: To ensure reliability, the Tax Map alternates between Set A and Set B each month. If one set has issues, the previous month’s copy remains online. Both sets are kept about a month apart and are available for download:
• Set A link
• Set B link

• Digital Alteration Book (DAB): The DAB is the official log of map changes—such as new lots, merges, or boundary shifts—providing a clear record of how the Tax Map evolves. It is available through the Property Information Portal. Coming soon the collection on Open Data will grow to include information from the Digital Alteration Book (DAB) that will keep track of historical changes to the Digital Tax Map.

The official tax maps for the City of New York are maintained by the DEPARTMENT OF FINANCE Tax Map Office. Tax maps show the lot lines, the block and lot numbers, the street names, lot dimensions, and easements. Please see the following link for additional documentation- https://github.com/CityOfNewYork/nyc-geo-metadata/blob/master/Metadata/Metadata_DigitalTaxMap.md

Publication Date: April 2025 2024 Parcel Data. Updated annually, or as needed. The data can be downloaded here: https://gis.ny.gov/parcels#data-download. This feature service has two layers: 1) NYS Tax Parcels Public, and 2) NYS Tax Parcels Public Footprint which contains polygons representing counties for which tax parcel polygons are available in the NYS Tax Parcels Public layer. County footprint polygons display when zoomed out beyond 1:37,050-scale. Tax parcel polygons display when zoomed in below 1:37,051-scale. The NYS Tax Parcels Public layer contains 2024 parcel data only for NY State counties which gave NYS ITS Geospatial Services permission to share this data with the public. Work to obtain parcel data from additional counties, as well as permission to share the data, is ongoing. To date, 36 counties have provided Geospatial Services permission to share their parcel data with the public. Parcel data for counties which do not allow Geospatial Services to redistribute their data must be obtained directly from those counties. Geospatial Services' goal is to eventually include parcel data for all counties in New York State. Parcel geometry was incorporated as received from County Real Property Departments. No attempt was made to edge-match parcels along adjacent counties. County attribute values were populated using 2024 Assessment Roll tabular data the NYS ITS Geospatial Services obtained from the NYS Department of Tax and Finance’s Office of Real Property Tax Services (ORPTS). Tabular assessment data was joined to the county provided parcel geometry using the SWIS & SBL or SWIS & PRINT KEY unique identifier for each parcel. Detailed information about assessment attributes can be found in the ORPTS Assessor’s Manuals available here: https://www.tax.ny.gov/research/property/assess/manuals/assersmanual.htm. New York City data comes from NYC MapPluto which can be found here: https://www1.nyc.gov/site/planning/data-maps/open-data/dwn-pluto-mappluto.page. Thanks to the following counties that specifically authorized Geospatial Services to share their GIS tax parcel data with the public: Albany, Cayuga, Chautauqua, Cortland, Erie, Genesee, Greene, Hamilton, Lewis, Livingston, Montgomery, NYC- Bronx, NYC- Kings (Brooklyn), NYC- New York (Manhattan), NYC- Queens, NYC- Richmond (Staten Island), Oneida, Onondaga, Ontario, Orange, Oswego, Otsego, Putnam, Rensselaer, Rockland, Schuyler, St Lawrence, Steuben, Suffolk, Sullivan, Tioga, Tompkins, Ulster, Warren, Wayne, and Westchester. Geometry accuracy varies by contributing county. This map service is available to the public.

This dataset represents a compilation of data from various government agencies throughout the City of New York. The underlying geography is derived from the Tax Lot Polygon feature class that is part of the Department of Finance's Digital Tax Map (DTM). The tax lots have been clipped to the shoreline, as defined by NYCMap planimetric features. The attribute information is from the Department of City Planning's PLUTO data. The attribute data pertains to tax lot and building characteristics and geographic, political and administrative information for each tax lot in New York City.The Tax Lot Polygon feature class and PLUTO are derived from different sources. As a result, some PLUTO records do not have a corresponding tax lot in the Tax Lot polygon feature class at the time of release. These records are included in a separate non-geographic PLUTO Only table. There are a number of reasons why there can be a tax lot in PLUTO that does not match the DTM; the most common reason is that the various source files are maintained by different departments and divisions with varying update cycles and criteria for adding and removing records. The attribute definitions for the PLUTO Only table are the same as those for MapPLUTO. DCP Mapping Lots includes some features that are not on the tax maps. They have been added by DCP for cartographic purposes. They include street center 'malls', traffic islands and some built streets through parks. These features have very few associated attributes.To report problems, please open a GitHub issue or email DCPOpendata@planning.nyc.gov.DATES OF INPUT DATASETS:Department of City Planning - E-Designations: 2/5/2021Department of City Planning - Zoning Map Index: 7/31/2019Department of City Planning - NYC City Owned and Leased Properties: 11/15/2020Department of City Planning - NYC GIS Zoning Features: 2/5/2021Department of City Planning - Polictical and Administrative Districts: 11/17/2020Department of City Planning - Geosupport version 20D: 11/17/2020Department of Finance - Digital Tax Map: 1/30/2021Department of Finance - Mass Appraisal System (CAMA): 2/10/2021Department of Finance - Property Tax System (PTS): 2/6/2021Landmarks Preservation Commission - Historic Districts: 2/4/2021Landmarks Preservation Commission - Individual Landmarks: 2/4/2021Department of Information Telecommunications & Technology - Building Footprints: 2/10/2021Department of Parks and Recreation - GreenThumb Garden Info: 1/4/2021

New York City data comes from NYC MapPluto which can be found here: https://www1.nyc.gov/site/planning/data-maps/open-data/dwn-pluto-mappluto.page. The State-owned tax parcel polygons in this file are the result of a best effort selection based on the Primary Owner and Additional Owner fields in the NYS Statewide Tax Parcels file, Geospatial Services data, State agency data, and online research. These same data and information are also the basis for a best effort assignment of a NYS agency name (listed in the NYS Name field) to most tax parcel polygons where the Owner Type field value is State. The NYS Name Source field consists of a code that describes how the State-owned designation and agency name were determined, if this was verified, and the means of verification, if applicable.This map service is available to the public.The State of New York, acting through the New York State Office of Information Technology Services, makes no representations or warranties, express or implied, with respect to the use of or reliance on the Data provided.

This layer contains parcels data for Oswego County, NY as taken from the current digitized version of the county tax maps. Originally drawn by Stewart Mapping Services, Inc of San Antonio Texas in 1975, but with digital topology corrected by Oswego County's Department of Real Property Tax Services from 1996-present. Contains taxable parcels attributed with assessment data taken from local assessment rolls.Geography is based upon the taxable status date of March 1st, 2025. Assessment attributes are from the latest final assessment roll (2024) except ownership which is updated bi-monthly on Fridays to reflect the most current owners of record. Click here to retrieve a data dictionary for decoding fields.Note: The original tax maps that these files were digitized from only had an accuracy between 10-20 feet on ground. While every effort is made to maintain this geographic data in an accurate format, the lines drawn from this data are fundamentally informational in nature and are not equivalent to survey grade. Geoprocessing has been applied to this specific web layer to allow faster drawing of lines which can further degrade the accuracy of their geometry. Finally, these parcels are used to create county tax maps which have the sole use case of giving assistance for local municipal assessors in the fulfillment of their duties, there is no warranty (expressed or implied) for any other use.

Albany County, New York, tax parcel boundaries with limited property information.A tax map is a special purpose map, accurately drawn to scale showing all the real property parcels within a city, town or village. These maps are used to locate parcels and obtain other information required in assessment work. The size, shape and dimensions (or acreage) of a parcel may be found on a tax map. Tax maps are primarily used by local governments to maintain a current inventory of all parcels in a city, town or village.Tax parcel boundaries are maintained by the Albany County Real Property Tax Service Agency. Albany County provides the municipalities with digital GIS files on an annual basis. Therefore, all parcel boundary changes may not be reflected in this GIS file, depending on the revision date.Real Property Information, as recorded and managed by the local municipal assessor is updated annually using the final roll taxable status date March 1 by the County and also may not be reflecting the most current information, depending on the information revision date.
