DOF publishes individual values for selected co-op developments. Missing apartments remain unverified. A value on this roll is not a resale appraisal, a separate apartment tax bill, or proof that a surcharge is owed.

+5.4% change in DOF market value from the prior year.
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.
Official DOF final assessment roll (ZIP) ↗FY2026–27 · DOF statement 2026-08-15 · 450 W. 23RD ST.
The printed annual tax already deducts $3,627.16 in abatements and/or STAR.
The before-abatement amount adds the printed deduction back to the annual tax, holding the assessment and rate unchanged. It does not predict benefit expiration, future taxes or a buyer’s eligibility.
DOF tax-purpose market value on this statement: $4,841,000.00.
Co-op/Condo Abatement 1 unit $3,627.16
This covers the whole tax lot. Co-op building taxes cannot be added to an apartment’s maintenance or divided among its units.
Read official DOF tax bill ↗How we calculate your annual taxes: Billable assessed value: $965,362.00 times the current tax rate: x 12.4390% minus abatements and/or STAR: – $3,627.16 Annual property tax: $116,454.24
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.
