Question or correct this record
BlockReport can explain a discrepancy, but it cannot rewrite an official City record. Use the agency that owns the underlying fact:
Property tax
The estimate, live balance, and back-tax record are different.
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.
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 2821725002026 taxable assessment equals the full assessed value.
Historical delinquency sources Record found
$12,026.37 was recorded for this parcel in Philadelphia's June 2022 delinquency snapshot for 1983–2021. That amount may have been paid, reduced, or increased since; it is not a current payoff figure.
$3,052.07 principal$6,517.69 interest$213.13 penalty$2,243.48 other charges
The snapshot’s 2022 context used $3,400 total assessment, $3,400 taxable, and $0 exempt/abated. Those historical fields can differ from today’s OPA exemption status.
A separate historical parcel ledger ending in 2016 records $10,120.93 and a lien entry. It is shown as historical context only.

Methodology & freshness
This report was assembled Jul 10, 2026, 3:30 PM 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.
