FY2026–27 · DOF statement 2026-08-15 · 84-20 51ST AVE.

The printed annual tax already deducts $65,384.64 in abatements and/or STAR.

The calculation deducts $10,373.00 in assessed-value exemptions before applying the tax rate.

Billable assessment on this statement: $1,984,880.00
Tax rate on this statement: 12.4390%
Annual tax before abatements/STAR: $245,608.96
Monthly equivalent before abatements/STAR: $20,467.41

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: $4,537,000.00.

Read official DOF tax bill ↗

How we calculate your annual taxes:
Billable assessed value: $1,984,880.00
minus exemptions: – $10,373.00
times the current tax rate: x 12.4390%
minus abatements and/or STAR: – $65,384.64
Annual property tax: $180,224.32

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.
