Project Goal

The Department of Finance (DOF) is the revenue service, taxing authority and recorder of deeds of New York City. The Property Valuation and Tax Mapping (PVTM) unit within DOF has been working to upgrade the tax map, integrate the property assessment and tax map functions, and improve the delivery of property information to taxpayers. The modernization effort focused on two upgrades. The first upgrade was to enable 3D rendering in the tax map. The tax map was restricted to only showing land boundaries in 2D and unable to render the air and subterranean boundaries relevant for condominium tax lots. The second upgrade was to integrate property related information into a single site. Property data was siloed in different systems, functions and websites

Business Problem Solved

The Department of Finance launched the Property Information Portal (PIP) which contains an upgraded map able to render in 3D and a property card with all relevant property information. The PIP is a one-stop shop portal for property owners. In a single site, property owners can

• View the property’s assessed value and exemptions
• Review building and land descriptions for accuracy
• Use shortcuts to review and pay the property tax bill, challenge the assessment, and
schedule appointments
• Submit lot mergers and sub-divisions
• Submit floorplan files to render in 3D
• Submit and track requests for changes to the Tax Map Office
• Track recent property recordings, such as ownership changes, for any New York City
property
• View the history of changes made to specific lots
