New York Property Tax Calculator
Estimate your New York property taxes. Assessment percentages vary widely by municipality — enter your actual uniform percent of value from your assessment notice, or leave at 100% if entering your assessed value directly.
The Formula
Annual Tax = Taxable Assessed Value × (Mill Rate ÷ 1,000)
Assessed Value = Market Value × Assessment Ratio (state-specific — see note below)
Mill Rate: 1 mill = $1 per $1,000 of assessed value. Enter your actual rate from your county tax bill.
