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.

Disclaimer:
This dataset reflects formal applications submitted to DOF but may not reflect the latest changes in other City systems (e.g., exemptions or buildings data). It is provided for informational purposes only and is not guaranteed to be accurate as of today’s date.

This application shows general City information such as the locations of fire stations and government services, and also tax information for all the parcels located in the City of Winchester, Virginia.

Index map page boundaries of the Mat-Su Borough Tax Map Page Index. The entire Borough is divided into a series of "base maps" and "index" or "grid maps". Base maps are given names that represent the geographical area represented (similar to USGS quad mapping) and index maps are numbered sequentially within the base map. The result is a base map with a two-character name (for example: ("WA" for Wasilla) and numbered index maps (usually numbered "1" thru "16"). The Mat-Su Borough tax map set is published using these pages.

Please note: this data is updated as of 2023.Overview of the Data:The operational purpose of the tax parcel data set is to facilitate the calculation and collection of property taxes. Each publicly or privately owned property in the city of Rochester has an official tax parcel record. This feature layer shows the polygon boundaries for each of the over 65,000 tax parcels in the city, along with several fields from their parcel records that detail information about the property, including ownership, property type, and assessed values. How does the tax map system work in New York State? What does Section, Block, Lot refer to?Each county in the state has a tax map that includes all of the parcels in each of its cities, towns, and villages. The county tax map is subdivided into sections of even, modular units that are 8,000 feet by 12,000 feet. Each of these sections are then subdivided into blocks of up to 100 parcels. Blocks are typically formed by following natural boundaries (i.e., roads, rivers, railroad tracks). Lot numbers are assigned to each parcel in a block following a set pattern according to their location on the map. Each parcel is thus assigned a Section, Block, Lot (SBL) number for identification and tax administration purposes. For more information on this identification system, please see the General Guide for Tax Mapping in New York State, put out by the Property Tax Assessment Administration.Related Resources:For a searchable interactive mapping application, please visit the City of Rochester's Property Information explorer tool.

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.

This feature layer provides digital tax parcels for the Organized Towns of the State of Maine. Within Maine, real property data is maintained by the government organization responsible for assessing and collecting property tax for a given location. Organized towns and townships maintain authoritative data for their communities and may voluntarily submit these data to the Maine GeoLibrary Parcel Project. "Maine Parcels Organized Towns Feature" and "Maine Parcels Organized Towns ADB" are the product of these voluntary submissions. Communities provide updates to the Maine GeoLibrary on a non-regular basis, which affects the currency of Maine GeoLibrary parcels data. Another resource for real property transaction data is the County Registry of Deeds, although organized town data should very closely match registry information, except in the case of in-process property conveyance transactions. In Unorganized Territories (defined as those regions of the state without a local government that assesses real property and collects property tax), the Maine Revenue Service is the authoritative source for parcel data. "Maine Parcels Unorganized Territory Feature" is the authoritative GIS data layer for the Unorganized Territories. However, it must always be used with auxiliary data obtained from the online resources of Maine Revenue Services (https://www.maine.gov/revenue/taxes/property-tax) to compile up-to-date parcel ownership information. Property maps are a fundamental base for many municipal activities. Although GIS parcel data cannot replace detailed ground surveys, the data can assist municipal officials with functions such as accurate property tax assessment, planning and zoning. Towns can link maps to an assessor's database and display local information, while town officials can show taxpayers how proposed development or changes in municipal services and regulations may affect the community. In many towns, parcel data also helps to provide public notices, plan bus routes, and carry out other municipal services.

This dataset contains municipality-submitted parcel data along with previously developed parcel data acquired through the Municipal Grants Project supported by the Maine Library of Geographic Information (Maine GeoLibrary). Grant recipient parcel data submissions were guided by standards presented to the Maine GeoLibrary Board on May 21, 2005, which are outlined in the "Standards for Digital Parcel Files" document available on the Maine GeoLibrary publications page (https://www.maine.gov/geolib/policies/standards.html). This dataset also contains municipal parcel data acquired through other sources; the data sources are identified (where available) by the field “FMSCORG”. Note: Join this feature layer with the "Maine Parcels Organized Towns ADB" table (https://maine.hub.arcgis.com/maps/maine::maine-parcels-organized-towns-feature/about?layer=1) for available ownership information. A date field, “FMUPDAT”, is attributed with the most recent update date for each individual parcel if available. The "FMUPDAT" field will not match the "Updated" value shown for the layer. "FMUPDAT" corresponds with the date of update for the individual data, while "Updated" corresponds with the date of update for the ArcGIS Online layer as a whole. Many parcels have not been updated in several years; use the "FMUPDAT" field to verify currency.
