BlockReport can calculate the annual tax from the City’s taxable assessment. Payments, credits, interest, and a current amount due live separately in Philadelphia Tax Center.
2026 taxable assessment $0 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $11,575,400; it is not the 2026 billed-year value.
A Tax Center balance is net of bills, payments, credits, interest, and adjustments. A credit—or an amount due—is not automatically “back taxes.”
OPA 7823224002026 OPA shows a zero or de minimis taxable assessment. The open assessment split does not establish the exemption's legal basis, continuing eligibility, or treatment after a transfer.
This parcel did not match the June 2022 delinquency snapshot. That absence does not confirm the account is current today.
For a purchase, refinance, or closing, request the City’s official Property Payoff statement in Tax Center under “More options.”

Select a point to read what happened; the line is an assessment history—not a sale-price chart or appraisal. OPA has also published a 2027 assessment of $11,575,400; it is not yet the billed-year tax basis.

This is a school, not a home, and OPA shows a full or near-full assessment exemption whose basis must be verified. A $0 assessment-based tax estimate does not prove the live Tax Center account has no prior-period balance or other charges. Homeowner investment tools are hidden; the assembled public-source record remains below.

This report was assembled Jul 11, 2026, 4:01 AM ET. Available City datasets are queried from OpenDataPhilly (phl.carto.com) and the cited City ArcGIS feeds; record queries paginate rather than silently taking a first page. For this property: Permits: queried · Violations: queried · Investigations: queried · Appeals: queried · Licenses: queried · Building certifications: queried. “Unavailable” means the source query failed or was not supplied, not “no record.” Reports re-pull on view after seven days and on an overnight rolling schedule; citywide benchmarks recompute weekly. Source dates still govern: the parcel-level tax-delinquency snapshot is June 2022 and the separate detailed tax ledger ends in 2016, so neither establishes today’s balance. The live balance and date-effective payoff must be verified in Tax Center. AI-written passages are grounded in the assembled record and rejected if they state a number the record does not hold.
