FY2026–27 final assessment roll · Extract 2026-05-15
+4.8% 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) ↗FY2025–26 · DOF statement 2025-11-15 · 34 W. 21ST ST.
DOF tax-purpose market value on this statement: $11,331,000.00.
This covers the whole tax lot. Co-op building taxes cannot be added to an apartment’s maintenance or divided among its units.
Read official DOF tax bill ↗How we calculate your annual taxes: Billable assessed value: $590,208.00 times the current tax rate: x 19.8430% Annual property tax: $117,115.00
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.

No exact offering-plan match has been collected here yet. Eligible condo and co-op properties are queued when viewed. Missing filings do not establish zero fees, assessments or debt.
Search the official NYAG offering-plan database ↗Tax-benefit schedules, statement balances, penalties and declared capital work cover the identified tax lot. Condo billing-lot evidence is shown separately from apartment evidence.
No supported financial amounts were returned in this source snapshot. This does not establish zero costs, no benefit, no debt or no penalties.
Balances retain the source’s reported status and observation date. An imposed penalty is not an additional amount to add to its balance due.
