Frequently Asked Questions
Answers to the most common questions about NYC property tax assessments, the pied-à-terre surcharge, over-inclusion errors, and the October 6, 2026 DOF challenge deadline.
The October 6, 2026 Deadline
The New York City Department of Finance (DOF) opens a formal challenge window each year during which property owners may contest their assessed valuations. The current window closes on October 6, 2026. Missing this deadline means waiting until the next cycle — typically another full year — before a challenge can be filed.
