Valuation/Assessment

Notice of Property Value
Every January, Finance mails New York City property owners a Notice of Property Value (NOPV). This notice is important because it has information about your property’s market and assessed values.

Your property’s value is used to calculate your property taxes for the next tax year.

Real Property Income and Expense (RPIE) Statements
Owners of income-producing properties that have an actual assessed value of more than $40,000 are required to file annual Real Property Income and Expense (RPIE) statements with Finance by September 1 of each year, unless the properties are specifically excluded from the filing requirements by law. Finance uses the information from these statements to estimate the market value of property.
