Allegheny County Assessor Property Search & Tax Lookup 2026

by
Allegheny County Pennsylvania Real Estate Navigator

Search Allegheny County Property Assessments, Lot & Block Records and Taxes

Allegheny County does not use a traditional elected “county assessor.” Property values are maintained by the Office of Property Assessments, while the elected County Treasurer collects county real-estate tax. Municipalities and school districts can impose additional property taxes through their own collectors.

The county still uses a 2012 base-year assessment system, so a number shown as the assessed value is not necessarily the property’s current 2026 market price. This guide shows how to find the correct parcel, decode the Lot & Block number, review building and owner history, check the 6.43-mill county tax, find delinquent balances and use the currently open 2027 annual assessment-appeal process.

2027 Allegheny County Assessment Appeals Are Open Now

The current annual appeal window is for tax year 2027. Property owners, municipalities and school districts may file a 2027 Annual Appeal from July 1 through September 1, 2026. There is no filing fee for an annual assessment appeal.
2026 values are certified Allegheny County certified 2026 assessment values on January 9, 2026. The regular filing window for tax year 2026 closed September 2, 2025.
2027 appeal deadline File online, by email, by mail or in person by September 1, 2026. Fax submissions are not accepted for annual appeals.
2027 Common Level Ratio The County’s newly published 2027 CLR is 49.3% and will be applied to current market value in appeals beginning in September 2026.
Tax-year distinction: A 2027 annual appeal filed now affects the 2027 assessment year. It does not retroactively rewrite a closed 2026 annual assessment merely because the application is submitted during calendar year 2026.
New parcels: Allegheny County warns that property being taxed by the County for the first time in 2027 may not appear in the Real Estate Portal until values are certified in January 2027. The County directs new-parcel questions to LandHelp@AlleghenyCounty.US.

  • Clean & Green
  • Assessment corrections
  • Appeal administration

County Treasurer

  • County real-estate tax
  • 2026 tax balance
  • Online payment
  • eBill subscription
  • Paid receipts
  • Tax certifications

Municipality / School

  • Satisfactions
  • Subdivision plans
  • Historical records
  • Certified deed copies
Do not treat the 6.43-mill county rate as the total property-tax rate. Allegheny County property owners can owe county, municipality and school-district taxes. Each layer can have a different millage, collector, discount period and due date.

Choose the Property Task You Need

Search assessment records Find the parcel by address or Lot & Block number, then review assessment, owner, building and exemption data.
Check 2026 county tax Open the Tax Information tab to see 6.43-mill county tax, discount, face tax, payment status and delinquent balance.
Find municipality and school tax Identify the property’s municipality and school district, then use the Treasurer’s local tax-collector and millage listing.
File a 2027 annual appeal Open the property, select Appeal Status and submit before September 1, 2026.
Claim Homestead relief Check whether “Homestead: Yes” appears in General Information and file Act 50 by March 1 when needed.
Find a deed or mortgage Use Allegheny County Land Records for the complete recorded ownership chain rather than relying on abbreviated owner history.

Parcel ID = Lot & Block

Understanding an Allegheny County Parcel Number

Allegheny County commonly calls the parcel identifier the Lot & Block number. The Real Estate Portal displays formatted parcel IDs such as 0368-R-00014-0000-00, while some tax-payment systems can show or accept the identifier without punctuation.

Assessment search Parcel ID connects directly to the County assessment record.
Tax payment Treasurer Easy Pay asks users to keep parcel ID / Lot & Block numbers available.
Appeal filing Open the parcel and use the Appeal Status tab to file an annual appeal.
Deed research Deeds recorded in Allegheny County must include parcel identification / Block & Lot numbers.
eBill enrollment The Treasurer links the taxpayer’s email address to the parcel ID.
Electronic bank pay The Treasurer recommends putting the parcel ID in the bank-payment account or memo field.
Do not use the old code-and-line convention when paying the County Treasurer. The Treasurer’s current tax system references the parcel ID / Lot & Block number.

What You Can Find Inside an Allegheny County Property Record

Six Things to Match Before Using the Record

Parcel ID Lot & Block
Address Property site
Municipality Tax jurisdiction
School district School levy
Tax year 2026 / 2027
Homestead Yes / No
Pittsburgh-address warning: ZIP code and mailing city can say Pittsburgh even when the parcel is in Penn Hills, Wilkinsburg, Ross Township or another municipality. Use the portal’s Municipality field, not the mailing address, to determine the taxing jurisdiction.
Allegheny County uses a 2012 base year

Why the Assessed Value May Look Much Lower Than the 2026 Sale Price

Allegheny County’s current base year is 2012, with an effective valuation date of January 1, 2012. The 2012 base year was first used for tax year 2013 and remains the foundation of current assessments. The County’s last countywide reassessment was in 2013.

2012 Base-Year Market Value The assessment system anchors ordinary parcel values to the base-year methodology.
This is not automatically the home’s 2026 sale value.
Property Changes Omissions, clerical errors, demolition, subdivision, permits and major improvements can affect assessment.
Check why one year differs from another.
Appeal Market Evidence In an appeal, parties can present current market-value evidence subject to Pennsylvania assessment rules.
Comparable sales and appraisal quality matter.
Taxable County Value Applicable exclusions reduce the value used for county-tax calculation.
Homestead can reduce county taxable value by $18,000.
Assessment change is limited: Outside the appeal process, the Office of Property Assessments identifies reasons such as omissions, mathematical or clerical errors, demolitions, subdivisions and building-permit changes as circumstances that can alter parcel values.
2026 Allegheny County tax = 6.43 mills

How to Calculate the County Portion of Property Tax

Allegheny County’s 2026 county real-estate tax rate is 6.43 mills. One mill equals $1 of tax per $1,000 of taxable assessed value.

One assessment, several tax bills

How Allegheny County Property Taxes Are Split

Allegheny County 2026 county millage is 6.43. The elected County Treasurer collects this portion and provides county online payment and receipts.
Municipality Boroughs, townships and the City of Pittsburgh can impose separate millage and use their own collector or contracted tax service.
School District School property tax is another major layer. The applicable district appears in the parcel’s General Information.
Search the parcel first. Record the Municipality and School District from General Information.
Check the County Treasurer’s 2026 millage listing. Open Local and School District Tax Millage.
Find the exact municipality. The Treasurer listing identifies the tax collector, phone number and 2026 municipal millage.
Confirm school tax separately. Use the school district associated with the parcel rather than guessing from the mailing address.
Save all receipts. County, municipal and school taxes can be paid to different offices.
Tax Information tab

How to Look Up Allegheny County 2026 Real Estate Tax

Search the property in the Real Estate Portal. Use the address or Lot & Block number.
Open “Tax Info eBill / ePay.” Desktop users can choose the tax tab at the top; mobile users may need the menu icon.
Confirm the 2026 millage. Current county real-estate tax records show 6.43 mills.
Check Taxable Market Value. If Act 50 applies, the tax page marks the taxable value after the county Homestead exclusion.
Review 2026 payment status. The history table shows tax, penalty, interest, total and payment date.
Check prior years. Older unpaid years can direct the owner to Jordan Tax Service for delinquent/liened county taxes.
Download the paid receipt. The Treasurer now makes electronic receipts available through the tax table rather than automatically mailing them.
Receipt timing: The Treasurer states that PDF receipts generally become available 7–10 business days after payment. Electronic receipt availability is limited to the current and immediately preceding year.
Closing or refinance: The online tax history is informational. A four-year tax certification bearing the Treasurer’s official seal can be requested for $25 when formal verification is required.
2026 county payment methods

How to Pay Allegheny County Property Tax

Free eCheck The Treasurer’s FORTE Easy Pay system currently offers eCheck without a taxpayer service fee.
Debit or credit card The Treasurer’s 2026 bulletin lists a 2.4% service fee for card transactions; verify the fee shown before authorizing payment.
Mail County tax payments may be mailed to Allegheny County Treasurer, PO Box 643385, Pittsburgh, PA 15264-3385.
In person Treasurer’s Office, Courthouse Room 108, 436 Grant Street, Pittsburgh, PA 15219.
Bank bill pay Put the parcel ID / Lot & Block number in the account or memo field so the payment is credited correctly.
eBilling Subscribe through the property’s eBill/ePay tab. The Treasurer sends annual e-bills during the first week of February.
Avoid unofficial bill-payment sites: The County Treasurer specifically warns that services such as doxo.com are not affiliated with Allegheny County. Use the Real Estate Portal and Treasurer’s contracted payment provider.
“I need to confirm the 2026 Allegheny County real-estate tax for Parcel ID __________. Please verify the current balance, penalty and interest through __________ and confirm whether any prior-year tax has been transferred to delinquent collection.”

Act 50 Homestead/Farmstead Exclusion

Allegheny County Homestead Exclusion

A qualifying owner-occupied primary residence can receive an $18,000 reduction in assessed value for Allegheny County real-estate tax. At the 2026 county rate of 6.43 mills, that equals approximately $115.74 in annual county-tax savings.

No annual refiling Once properly approved, owners generally do not file again every year.

Act 1 connection County qualification also activates the Act 1 exclusion for school-tax purposes without a separate application.
Search your property. Open General Information and find the “Homestead” field.

Download the Act 50 application. Use the official Homestead/Farmstead Exclusion page.

Acreage route The County identifies 10 acres as an important program qualification threshold.
Income route Qualifying agricultural property can also involve land capable of generating at least $2,000 annually in farm income.
June 1 deadline Applications are due by June 1 to become effective for the following calendar tax year.

Fire, flood or natural disaster

Catastrophic Loss Assessment Reduction

Pennsylvania law allows an Allegheny County assessment reduction when fire or another natural disaster causes damage that diminishes the property’s real-estate value by at least 50%.

50% threshold Damage must diminish real-property value by 50% or more.
Filing period Apply within six months after the loss or before the end of the calendar year, whichever gives the owner longer.
Real property only Personal belongings such as furniture, appliances and flooring are not the basis of the real-estate assessment reduction.
Document the event date. Keep fire, insurance, emergency-management or repair records.
Photograph structural damage. Exterior, interior, foundation and habitability evidence can help establish severity.
File even when the percentage is uncertain. The County advises owners to apply when significant structural damage exists because the filing window is limited.

Prior-year collection Jordan Tax Service collects delinquent/liened County real-estate taxes not previously sold to GLS.
Collection commission Applicable delinquent accounts can include a 10% collection commission plus postage and other recoverable charges.
Older lien exception Certain 1997 and 1998 County tax liens were sold to GLS Capital and require separate inquiry.
Open the parcel’s Tax Information. Review each year separately.

For prior years, follow the collector instruction. The portal can direct owners to Jordan Tax Service at 412-835-5243.
Ask for a complete payoff. Include tax, interest, penalty, lien charges, collection commission and fees.

City of Pittsburgh example

If the Property Is Actually Inside the City of Pittsburgh

A Pittsburgh mailing address is not enough. First confirm that the Real Estate Portal lists a City of Pittsburgh ward as the municipality. If it does, the owner has a separate City real-estate tax process in addition to Allegheny County tax.

2026 City millage The City’s current property-tax worksheet lists a 9.67-mill City rate.
City discount A 2% discount was available through February 10 for the annual City tax or first installment.
City installment dates February 27, April 30 and July 31, 2026.
The City schedule is not the County schedule. Allegheny County’s 2026 discount ended March 31 and face period ended April 30. City of Pittsburgh billing follows its own dates.
As of August 7, 2026: The City’s third 2026 installment due date of July 31 has passed. Owners with an unpaid Pittsburgh City bill should use the live City Real Estate system rather than an old installment coupon.
Open City of Pittsburgh Real Estate Taxes Use this only after confirming the parcel is within the City of Pittsburgh.

Allegheny County Assessor Property Search and Tax FAQs

1. How do I search Allegheny County property assessment records?

Use the Allegheny County Real Estate Portal and search by property address or parcel number. For an address search, enter the house number and street name without suffixes such as Street, Drive or Circle. Open the matching parcel and review General Information, assessment, building, tax, owner-history, appeals and map information.

2. Does Allegheny County have a county assessor?

Allegheny County property valuations are administered by the Office of Property Assessments rather than a traditional elected county assessor. Lou Fabian is the current Chief Assessment Officer.

3. What is an Allegheny County Lot & Block number?

The Lot & Block number is the parcel identifier used to connect assessment, tax, appeal and deed records. The Real Estate Portal displays a formatted Parcel ID, and the County Treasurer also uses the parcel ID for eBilling and payments.

4. Why is my Allegheny County assessed value lower than current market value?

Allegheny County still uses a 2012 base-year assessment methodology. The County explains that parcel assessments do not represent current-year market value; they reflect the base-year system with applicable property changes and appeal adjustments.

5. What is the Allegheny County property tax rate for 2026?

The 2026 Allegheny County real-estate tax rate is 6.43 mills, or $6.43 per $1,000 of taxable assessed value. This is only the County portion; municipality and school-district taxes are separate.

6. When were Allegheny County 2026 property taxes due?

The County’s 2% discount period ended March 31, 2026, the gross or face-tax period ended April 30, and the past-due period began May 1. Unpaid 2026 county tax receives a one-time 5% penalty plus 1% interest per month.

7. How much is the Allegheny County Homestead Exclusion?

The Act 50 Homestead/Farmstead Exclusion reduces the assessed value used for Allegheny County property tax by $18,000 for a qualifying primary residence. At the 2026 county millage, the typical county-tax savings is $115.74 per year.

8. What is the current Allegheny County assessment appeal deadline?

The current annual filing period is for tax year 2027 and runs from July 1 through September 1, 2026. Annual appeals have no filing fee and may be submitted online, by email, by mail or in person.

9. What is Allegheny County’s 2027 Common Level Ratio?

The Board of Property Assessment Appeals and Review currently lists the 2027 Common Level Ratio at 49.3%. The County states that this factor will be applied to current market value in appeals beginning in September 2026.

10. Where can I search Allegheny County deeds and mortgages?

Use the Allegheny County Division of Real Estate Land Records system. Recorded records include deeds, mortgages, mortgage satisfactions and subdivision plans. The Real Estate Portal’s owner history is useful for quick research but does not contain every historical transfer.

Use this free helper to find the right county office, prepare a property search, understand appraised value, review homestead exemption steps, and organize TRIM notice or tax bill questions before using official county websites.

Built for Florida county property guides
Helps users find official resources
No fake database or approval claim
Useful after every article

Find the Correct County Office

Property Appraiser, Tax Collector, Clerk, GIS, and VAB offices do different jobs. Pick your task below.

Quick rule: Property Appraiser = value, records, parcel details, exemptions. Tax Collector = bill and payment. Clerk/Recorder = deeds and recorded documents. VAB = formal value disputes.

Official Property Search Helper

Use this when a county article tells you to search by owner, address, parcel number, folio, PCN, STRAP, or alternate key.

Search tip: If address search fails, try only the house number and main street name. Avoid typing Street, Avenue, Road, Drive, unit numbers, or punctuation unless the official portal requires it.

Homestead Exemption Readiness Check

This helps homeowners prepare before filing through the official county Property Appraiser website.

Important: This is not an eligibility decision. The official county Property Appraiser decides approval, required documents, late filing options, and exemption status.
