Every January, the City's Department of Finance mails all New York City property owners a Notice of Property Value (NOPV). This notice is not a tax bill and does not require payment. The notice gives you information about your property, including its assessed value. The property's assessed value determines the property taxes for the upcoming year.
If an owner believes the property values or descriptions on the NOPV are incorrect, he or she can file a protest with the NYC Tax Commission and the Department of Finance.
