The New York City Council adopted Resolution 0961-2025 on June 30, 2025, to compute and certify the adjusted base proportion of each class of real property for Fiscal Year 2026 to the State Board of Real Property Tax Services. This action is mandated by Section 1803-a of the Real Property Tax Law and is based on the certified assessment rolls for Fiscal Year 2026, which were delivered by the Commissioner of the Department of Finance on May 27, 2025. The resolution acknowledges the need to adjust current base proportions to reflect additions to and removals from the assessment rolls, as well as other changes in assessed value. The Council is required to certify these adjusted proportions, along with assessed values and net changes, to the SBRPTS within five days of determination. This administrative resolution formalizes the real property tax framework for the upcoming fiscal year.
