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.”

Historical delinquency sources Record found
The June 2022 delinquency snapshot was not verifiably available in this cached report. No conclusion about a match—or today’s balance—can be drawn from that absence.

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 $51,100; it is not yet the billed-year tax basis.

Free record guide
How Philadelphia’s property system works
These explainers are free because the record only helps if you know what it can—and cannot—prove. Use the linked City guidance for the controlling rule.
Permits and inspections
A permit is the City’s authorization and review pathway for construction or repair work. No fetched permit is not proof that no work ever happened.
L&I inspections are scheduled at defined stages; final inspection and required certifications are separate steps in closing out applicable work.
How construction and repair permits work ↗See City inspection stages by permit type ↗Assessments and taxes
The OPA assessment is the City’s value on the tax roll—not an asking price, appraisal, or live account balance. The taxable assessment can differ from the full assessment because the City roll records exemptions or other treatment; the report keeps those fields separate.
Your annual estimate uses the taxable assessment. Payments, credits, interest, and the amount due are maintained separately in Tax Center.
How the Office of Property Assessment works ↗Philadelphia property-tax guidance ↗Violations, cases, and status
L&I enforcement records can include warnings, notices, orders, inspections, and later resolution activity. A closed visit is still a historical record; it is not a missing event.

Methodology & freshness
This report was assembled Jul 10, 2026, 3:08 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. “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.
