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.

Estimated annual Real Estate Tax$20,791/year

2026 taxable assessment $1,485,300 × 1.3998%. Estimate—not a bill or account balance.

OPA also publishes a 2027 assessment of $1,507,500; it is not the 2026 billed-year value.

Official current account balanceCheck live

A Tax Center balance is net of bills, payments, credits, interest, and adjustments. A credit—or an amount due—is not automatically “back taxes.”

Exemption classificationNo exemption shown

2026 taxable assessment equals the full assessed value.

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.

A separate historical parcel ledger ending in 2016 records $789.67 and a lien entry. It is shown as historical context only.

2016$789.67 total · $631.66 principal · $20.29 interest · $6.32 penalty

For a purchase, refinance, or closing, request the City’s official Property Payoff statement in Tax Center under “More options.”

What stands out

From the public record

Records to verify together

Rule-based groupings across this property's dated public records. Each flag shows the records that belong in the same verification step and where the inference stops.

Dated record flagRecords to verify together

More than one separately dated public record deserves a current-status check.

Evidence: 1 open L&I violation · a lien number appears in the historical tax ledger through 2016

Limit: A screening signal, not a foreclosure prediction. Tax entries are historical and must be verified with Philadelphia Revenue.

Transparent record rules, not a score or forecast. Each flag is a prompt to verify the cited records, not a prediction or allegation.

Where this comes from
Methodology & freshness

This report was assembled Jul 9, 2026, 9:58 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. “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.
