About Tax Maps

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.

Preparation of tax maps starts with the taking of aerial photographs that show roads, lakes, streams, railroad tracks, utility lines and other geographic features. All deeds or other instruments of conveyance are examined to determine the ownership of each parcel to be plotted on the maps. This process is also used for maintaining tax maps when changes occur, such as the formation of new subdivisions.

A tax map is generally drafted on map sheets 30 inches high by 42 inches wide. Parcels are indicated on the tax map using the data obtained through deed research and plotting. Every parcel is assigned a parcel number and a coordinate locator number. The parcel numbering system provides a history of how parcels are subdivided. An index map is prepared showing the area covered by the tax map in a city, town or village. Parcels are quickly located and additional information is easily obtained from the cross-reference index file.

Original maps remain where the maintenance is to be done. A CD is provided to each assessor where the public may view the tax maps. Copies are also available by contacting

A county tax map covers all the cities, towns and villages in the county. Each set of maps for a city, town and village is complete within itself. Each map sheet of a tax map covers one specific area, called a section. Every section is assigned a section number. The index map shows, and identifies, the areas covered by each of the section maps of that municipality.

Information for "About Tax Maps" comes from the NYS Office of Real Property Tax Services (NYS ORPTS) website. For a more detailed description of the tax mapping process, please visit them:
