Allegheny Property Tax: BPAAR Appeals & Rates (2026)

Direct answer: For Allegheny homeowners, the current annual assessment appeal is for tax year 2027 and must be filed July 1–September 1, 2026; the 2026-tax-year annual appeal window already closed on September 2, 2025. File through the Real Estate Portal’s Appeal Status tab, or submit the county’s Annual Appeal Form by email, mail, or in person to the Office of Property Assessments/BPAAR; there is no filing fee for the county-level annual appeal.

How assessments work in Allegheny

Allegheny County does not reassess every year to current market value. The Office of Property Assessments uses base-year methodology: the current base year is 2012, with an effective value date of January 1, 2012, and that base year has been used for tax year 2013 and later. The county says the last countywide reassessment was in 2013. (alleghenycounty.us)

That means the value on your county property record is generally not today’s market value. It is the county’s base-year assessed value, changed only for limited reasons such as omissions, mathematical or clerical errors, physical changes, demolitions, subdivisions, building permits, interim assessments requested by a taxing body, or catastrophic loss. Allegheny’s Administrative Code also prohibits “spot reassessment.” (alleghenycounty.us)

For appeals, the big local number is the Common Level Ratio (CLR). BPAAR states the 2027 Allegheny County CLR is 49.3%, applied to proven current market value in appeals starting in September 2026. In plain English: if you prove your home’s current market value is $360,000, the appeal value before exemptions would be about $177,480 ($360,000 × 49.3%). (alleghenycounty.us)

County tax is then calculated by multiplying taxable assessed value by the millage. The 2026 county real estate rate is 6.43 mills, or $6.43 per $1,000 of assessed value. School district and municipal taxes are separate and vary by where the property is located. (alleghenycounty.us)

Whether you should appeal

Start with this Allegheny-specific test: compare your current assessment to 49.3% of realistic current market value for the 2027 appeal cycle. If your current assessed value is materially higher than that number, an annual appeal may be worth filing. If it is lower, an appeal could backfire because BPAAR may increase, decrease, or sustain the assessment based on the evidence. (alleghenycounty.us)

Example: suppose your home is assessed at $220,000, but recent comparable sales and condition evidence support a current market value of $360,000. For 2027, $360,000 × 49.3% = $177,480. The assessment reduction would be $42,520. At the county rate of 6.43 mills, county-only savings would be about $273 per year ($42,520 × 0.00643). Your total savings could be higher once school and municipal millage are included, but you must use your exact local rates.

If you already have the Allegheny Homestead/Farmstead Exclusion (Act 50), remember it reduces the county-taxable assessment by $18,000 and is worth $115.74 per year at the 6.43-mill county rate. It does not replace an appeal; it is a separate tax-relief item to verify on your parcel’s General Information tab. (alleghenycounty.us)

I did not find an official countywide published success rate or median homeowner reduction for Allegheny assessment appeals. Treat any mailer or private claim about “typical savings” as marketing unless it cites a specific public dataset.

Step-by-step how to file

1. Look up your parcel. Use the Allegheny County Real Estate Portal and confirm the parcel ID, owner name, municipality, school district, current full base-year value, and whether “Homestead” shows Yes.

2. Decide which form applies. Use the Annual Appeal Form to challenge the county’s certified assessed value for the upcoming tax year. For 2027, applications may be submitted July 1 through September 1, 2026. Use the Special Appeal Form only for a notice of assessment change, interim assessment, Clean and Green, LERTA, Homestead/Farmstead determination, catastrophic loss, PURTA, or tax-exemption determination; a Special Appeal generally must be filed within 30 days of the notice letter. (alleghenycounty.us)

3. File by an accepted method. The county says annual appeals may be submitted online, by email, by mail, or in person; do not submit by fax. Online filing is through the Real Estate Portal: open your parcel and choose the Appeal Status tab. For paper filing, the Board rules list: County Office Building, 542 Forbes Avenue, Room 334, Pittsburgh, PA 15219, Attention: Appeals Manager. The prior annual appeal form also lists the email AnnualAppeals@AlleghenyCounty.US and the same Room 334 mail/delivery address; keep proof of submission. (alleghenycounty.us)

4. Do not send evidence with the appeal form. The annual form instructions say evidence is not sent with the filing form. After the hearing is scheduled, submit evidence by the deadline in your hearing notice. (alleghenycounty.us)

5. If someone represents you, file the authorization. Use Appeals Appointment of Authorized Representative if a lawyer, appraiser, family member, or other representative will act for you. The form lists mailing to Office of Property Assessments, 542 Forbes Avenue, Room 334, Pittsburgh, PA 15219, attn: Appeals Department, or email to AnnualAppeals@AlleghenyCounty.US. (alleghenycounty.us)

What happens after

The proper first-level appeal authority is the Allegheny County Board of Property Assessment Appeals and Review (BPAAR). BPAAR hears and decides assessment appeals under its rules; the Office of Property Assessments administers scheduling, hearing notices, postponements, and withdrawals. (alleghenycounty.us)

For 2026 hearings, Allegheny says hearings are conducted by telephone. Residential hearing notices are mailed at least 21 days in advance; commercial notices at least 30 days. You must provide the phone number for the hearing five days before the hearing and submit evidence ten days before the hearing to the county and opposing parties. (alleghenycounty.us)

At the hearing, the official assessment is entered first. The appellant then presents evidence supporting the requested value; other interested parties, such as the school district or municipality, may present evidence too. BPAAR uses relaxed evidence rules and may consider appraisals, photographs, estimates, invoices, comparable sales, income/cost evidence where relevant, and testimony. Comparable assessments alone are weak unless you also show they accurately reflect value. (alleghenycounty.us)

Allegheny does not describe a normal no-hearing written-only option for annual homeowner appeals; plan on a telephone hearing unless your notice or BPAAR tells you otherwise. You will not receive the decision the day of the hearing. BPAAR reviews the evidence and any recommendations, then sends a written disposition; you can track status on the Real Estate website’s Appeals tab. If you disagree, the next step is an appeal to the Court of Common Pleas, Board of Viewers, within 30 days of the BPAAR disposition letter’s mailing date. The county page lists a $135.25 non-refundable filing fee for that second-level appeal. (alleghenycounty.us)

Local tips

Use the 2027 CLR correctly. For this appeal window, the important comparison is not “what did I pay?” by itself; it is the supported current market value multiplied by 49.3%. A recent arm’s-length sale of your own home can be powerful, but only if the resulting CLR value is below the current assessment.

Watch school-district appeals. In Allegheny, property owners, municipalities, and school districts can appeal. If a school district files on your property, the county says you are not required to attend, but you may attend and present evidence. Do not ignore the notice if the requested value would raise your taxes. (alleghenycounty.us)

Check exemptions before appealing. Owner-occupants should verify Act 50 Homestead. Eligible seniors should check Act 77 Senior Tax Relief: the Treasurer says eligible seniors 60+, widows/widowers 50+, and permanently disabled adults 18+ with household income of $30,000 or less, who have continuously owned and occupied an Allegheny primary residence for at least 10 years, may receive a 30% discount on county property taxes; applications are due June 30 for current-year relief. Disabled veterans with a 100% service-connected disability should contact Allegheny County Veterans Services about exemption eligibility. (alleghenycountytreasurer.us)

Catastrophic loss has its own route. If fire or natural disaster damage reduces a structure’s value by 50% or more, the county’s Catastrophic Loss Form says to file within six months of the loss, or within the remainder of the calendar year, whichever is longer, to 542 Forbes Ave., Room 347, Pittsburgh PA 15219, Attention: Legislative Acts. (alleghenycounty.us)

Allegheny Property Tax Rate

2026 Allegheny County real estate tax rate: 6.43 mills ($6.43 per $1,000 of assessed value; 0.00643). Official example: a property assessed at $100,000 owes $643.00 before the Homestead exclusion; with the $18,000 Act 50 Homestead exclusion, the taxable assessment is $82,000 and county tax is $527.26, a $115.74 savings.

When Are Property Taxes Due in Allegheny?

2026 Allegheny County real estate taxes: 2% discount period ends March 31, 2026; gross/face tax payment period ends April 30, 2026; past-due period begins May 1, 2026. Approved Act 77 Senior Citizen Tax Relief taxpayers may choose an installment option: gross county taxes in two equal installments, first due April 30 and second due September 30. 2% discount if paid by March 31, 2026.

This is not the same as the assessment appeal deadline above. The appeal deadline is your window to contest your assessed value; the payment due date is when the resulting tax bill must be paid. Missing one does not affect the other, but missing either has real consequences — one forfeits your right to appeal for the year, the other can trigger penalties and interest.
