2026 taxable assessment $50,000 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $53,400; it is not the 2026 billed-year value.

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
$369.93 was recorded for this parcel in Philadelphia's June 2022 delinquency snapshot for 2017–2020. That amount may have been paid, reduced, or increased since; it is not a current payoff figure.
$53.78 principal$64.23 interest$35.48 penalty$216.44 other charges
The snapshot’s 2022 context used $15,900 total assessment, $15,900 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 $88.55 and a lien entry. It is shown as historical context only.
2015$88.55 total · $0.00 principal · $0.00 interest · $0.00 penalty

View supporting records →What to do with this
The record, translated into moves — what a buyer, the owner, and a landlord would each want to check next under Philadelphia's actual rules.
If you’re buying
Built 1915: lead rules apply
Federal law requires a lead-paint disclosure at sale for any pre-1978 home. If it will be rented, Philadelphia also requires a lead-safe or lead-free certificate before a rental license can issue.
Zoned RSA5: one household by right
Single-family rowhouse (the classic Philly row). Converting to a duplex or apartments needs a use variance the zoning board rarely grants — Pennsylvania courts require a physical hardship of the lot itself, and economics alone do not qualify.
If you own it
$89 in the historical tax ledger through 2016
Historical context only, not a current payoff figure; that ledger also contains a lien entry. Verify today's balance and lien status directly with Philadelphia Revenue before relying on it.
If you’re the landlord
If it is rented, verify the Rental License
The fetched license records do not show an active Rental License. Ownership type or a tax mailing address does not prove that tenants occupy the property; if it is rented, verify the current license and legal occupancy in eCLIPSE.
Derived from the fetched property records and linked City guidance as of 2026. Assessment treatment is not a substitute for an exemption approval, live balance, title report, license, occupancy certificate, or inspection. Informational only — not legal, tax, or investment advice.

Methodology & freshness
This report was assembled Jul 10, 2026, 3:29 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.
