Allegheny County Tax Assessment Search & Records

Search the Assessment, Decode the Value, Finish the Property Task

Use the Allegheny County Real Estate Portal to locate a parcel by street address or Lot & Block parcel number, then review assessed values, building characteristics, ownership, tax information, Homestead status, sales, appeal activity and map details.

Allegheny County is unusually easy to misunderstand because it still uses a 2012 base-year assessment system, unrestricted owner-name searching is not part of the ordinary free public search, county taxes are separate from municipal and school taxes, and the current annual appeal being filed in August 2026 is for tax year 2027—not 2026.

Start with quick answer Search assessment records Check 2027 appeal
Current August 2026 priority: the annual filing period for tax year 2027 is open now and ends September 1, 2026. The regular annual appeal window for tax year 2026 closed in 2025. Do not file against the wrong assessment year.

Quick answer: search by address or Lot & Block number

The free Allegheny County Real Estate Portal supports public searches by property address and parcel number. For an address, enter the house number and main street name without suffixes such as Street, Road, Drive or Circle. Leave Municipality blank if you are unsure. Open the matching parcel and verify the physical address, municipality and Lot & Block ID before using the assessment or tax information.

1 Search cleanly House number + main street name, or exact parcel ID.
2 Verify jurisdiction Confirm municipality and school district—not only Pittsburgh mailing city.
3 Save Lot & Block Reuse the parcel ID for taxes, deeds, copies and appeals.
4 Choose the office Assessment, Treasurer, Real Estate or BPAAR.

Portal software note: the public-facing system is branded simply as the Allegheny County Real Estate Portal. It is not presented to ordinary searchers as Beacon, qPublic or EagleView. Do not assume instructions from another county’s portal apply here.

Once you understand the search format above, use the official portal. Start with the fewest reliable fields; adding an incorrect municipality or street suffix can prevent a valid property from appearing.

Allegheny’s assessment method

Why the county still shows a 2012 base-year value

Allegheny County uses a base-year methodology with an effective date of value of January 1, 2012. The 2012 base-year system was used beginning with tax year 2013, and the last countywide reassessment occurred for that cycle.

When a certified property assessment can change

Omitted property or improvement
Mathematical or clerical error
New construction or addition
Demolition
Subdivision or parcel change
Interim assessment after qualifying improvement
Successful annual or special appeal
Qualifying catastrophic loss
Do not use Ohio’s 35% rule here. Allegheny County does not use an Ohio-style rule where every ordinary assessed value is simply 35% of current market value. Its regular records use the 2012 base-year system, while Common Level Ratios are used for specific appeal valuation purposes.

The 2027 annual assessment appeal window is open now

Opened July 1, 2026

2027 annual appeal filing began.

Deadline September 1, 2026

File the 2027 Annual Appeal by this date.

Filing fee $0

The county publishes no filing fee for the annual appeal.

2027 Common Level Ratio: 49.3%

Allegheny County has published a 49.3% Common Level Ratio for tax year 2027, to be applied to current market value in applicable appeals beginning in September 2026.

The CLR is not the county tax rate and it is not a blanket percentage automatically multiplied against every parcel in the ordinary Real Estate Portal.

File the annual appeal through the property record

Search the correct parcel Confirm Lot & Block, physical address, municipality and school district.

Gather evidence of current market value Focus on relevant recent sales, appraisal evidence, condition documentation or other valuation evidence.

State the requested value clearly Base the request on valuation evidence—not simply the amount of tax you would prefer to pay.
Submit by September 1, 2026 The county permits online, email, mail and in-person filing. Annual appeals should not be faxed.
Save filing confirmation Keep the submitted form, receipt and evidence with the parcel ID.

10 practical answers

Allegheny County tax assessment FAQs

How do I search Allegheny County tax assessment records?

Use the official Allegheny County Real Estate Portal. Search by property address or Lot & Block parcel number, open the matching parcel and verify the physical address, municipality and school district before relying on assessment or tax information.

Why does my Allegheny County address search return no result?

The portal instructs users not to include street suffixes such as Street, Road, Drive or Circle. Enter the house number and main street name, and leave Municipality blank if you are uncertain which borough, township or city contains the parcel.

Can I search Allegheny County property records by owner name?

The ordinary free public search is based primarily on address or parcel number. Current owner information appears after a parcel is opened. Allegheny County offers paid subscription access for owner-name searching and additional services.

Why does Allegheny County still use a 2012 assessment value?

Allegheny County uses a 2012 base-year assessment methodology. The base-year system was used beginning with tax year 2013, so the assessed value should not automatically be treated as the property’s current 2026 market price.

What is the 2027 Allegheny County assessment appeal deadline?

The 2027 annual appeal filing period runs from July 1 through September 1, 2026. There is no filing fee for the county annual appeal, and the online filing option can be reached through the parcel’s Appeal Status tab.

What is Allegheny County’s 2027 Common Level Ratio?

Allegheny County publishes a 2027 Common Level Ratio of 49.3%. It is used for applicable appeal calculations beginning in September 2026 and should not be confused with the county millage or a universal assessment percentage.

What are the 2026 Allegheny County property-tax deadlines?

The 2% county-tax discount period ended March 31, 2026, and the gross or face-payment period ended April 30, 2026. The past-due period began May 1, with a published one-time 5% penalty plus 1% monthly interest on delinquent county tax.

How does the Allegheny County Homestead Exclusion work?

Act 50 reduces qualifying owner-occupied property by $18,000 of assessed value for Allegheny County tax purposes. Applications are due by March 1 for current-year effect, and recent buyers should confirm that the Homestead status belongs to the new owner rather than the seller.

How do I get an Allegheny County Property Record Card?

You can request a Property Record Card electronically by emailing LandHelp@AlleghenyCounty.US. The county also publishes paper Property Record Cards at $0.25 per page through the Real Estate Department Copy Desk.

Where do I find Allegheny County deeds and mortgages?

Use the Allegheny County Division of Real Estate and its land-record resources. The assessment portal may show deed book, deed page and owner-history clues, but it does not contain every recorded ownership transaction or provide a title opinion.

Information reviewed August 22, 2026: the public Real Estate Portal search rules, paid owner-search subscription, 2012 base-year assessment method, 2027 annual-appeal window, 2027 Common Level Ratio, annual and Special Appeal rules, 2026 county millage and payment dates, delinquent penalty and interest, Act 50 Homestead exclusion, Act 77 Senior Tax Relief, Property Record Card copy costs, land-record routing, Division of Real Estate fees and office contacts were checked against current Allegheny County, Allegheny County Treasurer and Pennsylvania official sources.

Verify with the official Ohio source

These calculators use the verified 2026 Ohio Department of Taxation amounts and statutory rules. For your exact bill, exemption status, and county-specific deadlines, always confirm with your county auditor and the Ohio Revised Code:

Ohio Dept. of Taxation — Real Property DTE Forms (105A, 105C, 1, 109) ORC 5715 — Board of Revision ORC 5713 — Taxable Real Property ORC 322.02 — Conveyance Fee ORC 319.54(F)(3) — State Fee ORC 5713.30 — CAUV tax.ohio.gov — Main Portal

Estimates use Ohio's 35% statutory assessment ratio and effective tax rate tiers averaged across major Ohio counties. Your actual bill depends on local school levies, voted millage, inside vs. outside millage splits, House Bill 920 reduction factors (HB 920), and special assessments. The 2026 Homestead general amount ($29,000) and enhanced amount ($58,000) reflect HB 187 inflation indexing — your county auditor's office may show slightly different transitional figures.
