The Real Property Tax Service main objective is to educate, advise and assist county government, local governments, local property owners, and the public in general, in the area of real property assessment administration. One of the most visible functions is to provide updated tax maps on an annual basis to local city, town and village assessing units in Niagara County. The office trains and assists local assessors in the annual preparation of assessment and tax rolls for towns, schools and villages. Corrections to tax rolls and bills are processed through this office. We provide administrative support, cooperation and assistance to the local Assessors and the acting Boards of Assessment Review in Niagara County. Tax computations, Tax rolls and Tax bills are generated from our office and administered by the local tax collectors.

The majority of functions of the Real Property Tax Service Agency (RPTSA) are mandated by Article 15A of the Real Property Tax Law.
