The Local Government Tax Data Verification system (LGTDV) is a secure web application where Counties (and towns and cities in Westchester County) can report and review their real property tax roll information. Once reported through the Tax Data Verification system, the data is reviewed by OSC staff before being published to the Real Property Tax Levies, Taxable Full Value and Full Value Tax Rates page on the Office of the State Comptroller website. OSC staff will discuss the tax roll collection process, review process, and how the data is used. Any local officials who provide OSC with tax roll information are invited.
