Property Tax Assessment Values Across Tappan, Rockland County, New York

When examining property taxes in Tappan, New York, understanding the distinction between market value and assessed value is crucial.

The market value is what a willing buyer would pay to a willing seller in an open and competitive market, often influenced by location, property condition, and economic market trends. The Rockland County appraisal district estimates the market value for tax purposes.

The assessed value is the market value minus any applicable exemptions or limits determined by local laws and offerings. The tax assessed value is the figure used to calculate your property taxes or the amount multiplied by your tax rate to get your tax bill.

Assessment notices are sent in the spring each year and typically reach your mailbox by the middle of the month. Each property owner receives an assessment notice that contains both the market value and assessed value, along with an estimate of your property tax bill.

For example, the median home price in Tappan is $530,452, with the median tax bill at $14,647. That is far above the national median property tax bill of $2,400 and reflects a much higher local tax burden.
