The Department of Taxation and Finance annually produces a data file providing property tax rates and levies for the taxing jurisdictions in New York State. The data are culled from files on the State Comptroller’s website. The dataset takes each school district segment and provides the levy for county, municipal and school tax purposes, as well as the tax rates that apply in those taxing jurisdictions.

The Department of Taxation and Finance annually produces a report pertaining to the exemptions from real property taxation in New York State. The data analysis includes an examination and summary of exemptions by type or purpose for each municipality in the State. The summary data include the number of exemptions in each type or purpose, as well as the full value of the exemption amounts. The types are first broken down into categories of properties that are wholly exempt (and subsequently, not taxable for real property purposes) and those which are partially exempt. Within those categories, further analysis of the type of ownership of these exempt properties is examined. Specifically, these types of ownership are public and private. Additionally, some properties may have exemption codes that are not contained in an agency maintained list of valid codes. The data file contains a summary by count and full value of these invalidly coded properties, as well. Finally, properties may have exemptions for various taxation purposes, also stated as taxing jurisdictions. Those purposes are County, City/Town, and School taxation. This dataset contains columns with the count and full value for exemptions in each of these taxing jurisdictions.

The Department of Taxation and Finance annually produces a report pertaining to the exemptions from real property taxation in New York State. The data analysis includes an examination and summary of exemptions by exemption code for each municipality in the State. The summary data include the number of exemptions in each code, the assessed value of the parcels containing the exemption code and the exemption amount itself, as well as the estimated full value of both the parcels containing the exemption code and the exemption amount.

In 2017, the County Department of Economic Development, in conjunction with Reinvestment Fund, completed the 2016 Market Value Analysis (MVA) for Allegheny County. A similar MVA was completed with the Pittsburgh Urban Redevelopment Authority in 2016. The Market Value Analysis (MVA) offers an approach for community revitalization; it recommends applying interventions not only to where there is a need for development but also in places where public investment can stimulate private market activity and capitalize on larger public investment activities. The MVA is a unique tool for characterizing markets because it creates an internally referenced index of a municipality’s residential real estate market. It identifies areas that are the highest demand markets as well as areas of greatest distress, and the various markets types between. The MVA offers insight into the variation in market strength and weakness within and between traditional community boundaries because it uses Census block groups as the unit of analysis. Where market types abut each other on the map becomes instructive about the potential direction of market change, and ultimately, the appropriateness of types of investment or intervention strategies. The 2016 Allegheny County MVA does not include the City of Pittsburgh, which was characterized at the same time in the fourth update of the City of Pittsburgh’s MVA. All calculations herein therefore do not include the City of Pittsburgh. While the methodology between the City and County MVA's are very similar, the classification of communities will differ, and so the data between the two should not be used interchangeably. Allegheny County's MVA utilized data that helps to define the local real estate market. Most data used covers the 2013-2016 period, and data used in the analysis includes: •Residential Real Estate Sales; • Mortgage Foreclosures; • Residential Vacancy; • Parcel Year Built; • Parcel Condition; • Owner Occupancy; and • Subsidized Housing Units. The MVA uses a statistical technique known as cluster analysis, forming groups of areas (i.e., block groups) that are similar along the MVA descriptors, noted above. The goal is to form groups within which there is a similarity of characteristics within each group, but each group itself different from the others. Using this technique, the MVA condenses vast amounts of data for the universe of all properties to a manageable, meaningful typology of market types that can inform area-appropriate programs and decisions regarding the allocation of resources. During the research process, staff from the County and Reinvestment Fund spent an extensive amount of effort ensuring the data and analysis was accurate. In addition to testing the data, staff physically examined different areas to verify the data sets being used were appropriate indicators and the resulting MVA categories accurately reflect the market. Please refer to the report (included here as a pdf) for more information about the data, methodology, and findings.

This dataset is comprised of the final assessment rolls submitted to the New York State Department of Taxation and Finance – Office of Real Property Tax Services by 996 local governments. Together, the assessment rolls provide the details of the more than 4.7 million parcels in New York State. The dataset includes assessment rolls for all cities and towns, except New York City. (For New York City assessment roll data, see NYC Open Data [https://opendata.cityofnewyork.us]) For each property, the dataset includes assessed value, full market value, property size, owners, exemption information, and other fields. Tip: For a unique identifier for every property in New York State, combine the SWIS code and print key fields.
