FY2026–27 final assessment roll · Extract 2026-05-15
-0.1% 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 · 521 WEST 135 STREET APT 20
The calculation deducts $302,330.00 in assessed-value exemptions before applying the tax rate.
DOF tax-purpose market value on this statement: $1,493,000.00.
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: $584,190.00 minus exemptions: – $302,330.00 times the current tax rate: x 12.4390% Annual property tax: $35,060.60
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.
Look up this tax lot at DOF ↗NY Attorney General offering plans and amendments can document budgets, financial statements, reserves and sponsor obligations. These records cover the development, including properties without active listings.
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.

Final exemption values reduce assessed value; they are not cash savings or annual taxes. No expiration date inferred from a start year or duration.
Published benefit amounts and dates do not guarantee eligibility after a purchase. An end date alone does not establish the future tax bill; assessment, tax rate and other benefits may change.
