BlockReport can explain a discrepancy, but it cannot rewrite an official City record. Use the agency that owns the underlying fact:

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$42,890/year

2026 taxable assessment $3,064,035 × 1.3998%. Estimate—not a bill or account balance.

OPA also publishes a 2027 assessment of $7,725,100; 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.”

OPA 881068611
Open Philadelphia Tax Center →Choose “View period balance” to see the tax year and any credit, interest, or delinquency.
Exemption classificationPartial assessment exemption — basis unverified

2026 OPA taxes $3,064,035 of $7,410,000 assessed. The assessment fields alone do not identify a program, approval date, expiration, or buyer eligibility.

Full-assessment scenario$103,725/year

Applying the same rate to the billed-year full assessment. OPA's numeric split does not say when or whether the current treatment changes.

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 a balance and a lien entry. It is shown as historical context only.

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
Finding

"Built 1900" is usually a placeholder

Why it matters

Philadelphia records use 1900 as a stand-in when the real construction year was never documented. Treat the age as unknown, not as 120+ years.

The property record, over time

Every dated deed, permit, inspection, license, violation, certification, and appeal is placed on the City’s annual assessment line. 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 $7,725,100; it is not yet the billed-year tax basis.

Where the record looks off

Places where the city's own paperwork disagrees with itself. These are flags on the data — not problems with the property.

"Built 1900" is usually a placeholder

Philadelphia records use 1900 as a stand-in when the real construction year was never documented. Treat the age as unknown, not as 120+ years.

Where this comes from

Methodology & freshness

This report was assembled Jul 9, 2026, 10:24 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.
