DOF values are used for property taxation. Condo and co-op tax valuations can differ substantially from sale prices. This is a tax-purpose estimate; comparable sales remain a separate valuation source. Roll exemptions can include STAR under DOF’s published layout.

These values cover the whole tax lot and do not value individual co-op shares.

DOF tax-purpose market value on this statement: $1,390,000.00.

This covers the whole tax lot. Co-op building taxes cannot be added to an apartment’s maintenance or divided among its units.

How we calculate your annual taxes:
Billable assessed value: $53,504.00
times the current tax rate: x 19.8430%
Annual property tax: $10,616.80

HOA, common charges and maintenance require documented building or unit evidence. Sales and DOB records do not establish these amounts. A zero property-tax bill does not establish zero PILOT or other ownership charges. Bills may change with tax rates or benefits; monthly figures are annual equivalents.
