If you are a property owner in New York City, every January, the Department of Finance mails you a Notice of Property Value (NOPV). The NOPV is not a tax bill and does not require a payment. The NOPV gives you information about your property, including its assessed value. The property's assessed value determines your property taxes for the upcoming year.
If you believe your property value or the descriptions on your NOPV are incorrect, you can file a protest with the NYC Tax Commission and the Department of Finance.
If you have received a "Notice of Revised Property Value" from the Department of Finance due to Hurricane Sandy's impact on your property, you can appeal the assessed value on your NOPV with the NYC Tax Commission. You have 20 calender days from the date of the NOPV to do so. For Tax Class 1 properties, use Form TC108. For Tax Class 2 and Tax Class 4 properties, use Form TC101, and TC201. Include a copy of your "Notice of Revised Property Value" with your appeal.
