Allegheny County assessments, the court-ordered reassessment, appeal deadlines, hearings and evidence, in plain English. Search below or browse by topic.
A court has ordered one. On August 17, 2026, the Allegheny County Court of Common Pleas ordered the County to conduct a countywide reassessment, the first since the 2012 base year.
The current system stays in place. Assessments remain tied to the 2012 base year, the Common Level Ratio (49.3% for appeals filed July 1 to September 1, 2026, for tax year 2027) is applied to current market value shown at appeal hearings, and under the County's current schedule annual appeals are due September 1 for the following tax year.

Short answer: if you are over-assessed, usually yes. New values from the court-ordered reassessment do not have to be in place until June 30, 2032. Until then, every tax bill is based on your current assessment.
The County has not yet posted the tax year 2028 dates. Based on its current schedule, the next deadline is expected to be September 1, 2027 (tax year 2028). Check the County's Annual Appeals page for the posted dates.

Maybe, maybe not. It depends on how your property's value changed compared with others in your school district and municipality.
Longtime owner-occupants with qualifying income may be protected on county taxes by the Longtime Owner-Occupant Program (LOOP).

No. You are not required to let anyone into your home. The court's order allows the County and its contractor to use in-person data collection, computer modeling and aerial photography. That does not give anyone the right to enter your home without your consent.
Received a questionnaire or a visit? Call us first: 412.802.6666.
Yes. When new values are mailed, the County will announce how to request a review and file a formal appeal. In the 2012 reassessment, owners could request an informal review before filing a formal appeal.
We will post the County's review and appeal deadlines on our Reassessment Guide as soon as they are announced.

Your assessment is the value Allegheny County assigns to your property for tax purposes. Your County, school district and municipality each multiply that same assessment by their own millage rate to produce your tax bill.
Look up your parcel on the Allegheny County Real Estate Portal. Your assessment is shown as the full base year market value.
Allegheny County uses a 2012 base year. Your assessment is supposed to reflect what your property was worth on January 1, 2012, in its current condition, not what it is worth today. A court-ordered countywide reassessment will replace these values by June 30, 2032, at the latest.
If the home is your primary residence and you have the homestead exclusion (Act 50), your County taxable value is reduced. School and municipal taxes still use the full assessment unless those bodies offer their own exclusion.
Yes, every year. Annual appeals are filed between July 1 and September 1 for the following tax year. The County has not yet posted the tax year 2028 dates. Based on its current schedule, the next deadline is expected to be September 1, 2027 (tax year 2028). Check the County's Annual Appeals page for the posted dates.

Yes. Until the court-ordered reassessment takes effect, the 2012 base year controls every Allegheny County assessment and appeal.
At an appeal hearing, the party who filed must declare which value they are proving:
That ratio applies to appeals filed July 1 to September 1, 2026, for tax year 2027.
If you prove your home is worth $300,000 today, its assessment for tax year 2027 should be about $147,900 ($300,000 × 0.493). If your assessment is well above that, you may be over-assessed.
A new CLR is set each year, so check the current ratio before you file.
Not sure which approach fits your property? Call 412.802.6666.
Your assessment comes from the County's last countywide reassessment, which set values as of January 1, 2012.
For that reassessment, the County used a computer-assisted mass appraisal (CAMA) system. It compared each property to similar properties in its neighborhood using characteristics such as size, rooms, age and lot, along with sales from the years leading up to 2012.
Check your data. Request your free Property Record Card by emailing landhelp@alleghenycounty.us. Wrong square footage, room counts or condition can inflate your value, and those records will be the starting point for the coming reassessment.

Many are not — the only way to know is to compare it with recent sales. Many Allegheny County assessments have drifted over the years because of appeals, permits and data errors. The fastest way to check is a 60-second test, or use our free Am I Over-Assessed? calculator:
Example: A home worth $250,000 × 0.493 = $123,250. If the assessment is $160,000, the owner may be over-assessed.
Before you file, remember that an appeal can also raise an assessment. We will tell you honestly whether yours is worth pursuing.

Allegheny County has reassessed only when a court made it.
The County has said it plans to reassess every five years after this one.
See our Allegheny County Reassessment Guide for the current timeline.
Formula: Assessment × Millage ÷ 1,000 = Tax, calculated separately for the County, your school district and your municipality, then added together.
These rates are only an example. School and municipal millage varies widely across Allegheny County, so two identical assessments can produce very different bills.
Every $10,000 cut from your assessment saves $10 for each mill you pay. At 31.43 total mills, that is about $314 a year, every year until your assessment changes again.
Look up current rates: Allegheny County publishes municipal and school district millage rates each year.
Want us to run your numbers? Call 412.802.6666.
Each of your three taxing bodies sets its own millage rate.
An appeal changes your assessment, not the millage. But because every taxing body multiplies the same assessment, one successful appeal lowers all three bills.
After the reassessment: Pennsylvania's anti-windfall rules require each taxing body to roll back its millage so the reassessment itself does not create a revenue windfall. Watch your local budget votes in the first year new values take effect.
The most direct way is to lower your assessment through an appeal. Your tax bill is your assessment multiplied by the millage of three taxing bodies, so a lower assessment lowers all three.
Appeals are filed July 1 to September 1 for the following tax year. The County has not yet posted the tax year 2028 dates. Based on its current schedule, the next deadline is expected to be September 1, 2027 (tax year 2028). Check the County's Annual Appeals page for the posted dates. There is no County filing fee.
Use the "report data errors" option on the Real Estate Portal if your property record is wrong.

The County posts the annual appeal form during the filing window, which runs July 1 to September 1 for the following tax year. The form is removed after the deadline.

Want us to file for you? Call 412.802.6666.
Do not assume it arrived. Confirm it.
Our tip: keep a copy of everything you file and any confirmation you receive. If you file in person, ask for a time-stamped copy.
While you wait, check that your mailing address and phone number are correct with the County. Hearing notices are mailed, and hearings are held by phone.
September 1 of the year before the tax year you are appealing. The filing window opens July 1.
Allegheny County used to take appeals during the tax year itself. Under the Board's current rules, beginning with tax year 2027, annual appeals are prospective: they are filed and heard in the year before the tax year.
The reassessment does not change this deadline. Annual appeals continue under the 2012 base-year system until new values are implemented.
Want to know if you should file? Call 412.802.6666 for a free review.
Your first hearing is before the Board of Property Assessment Appeals and Review (BPAAR). All BPAAR hearings are held by telephone, and a hearing typically lasts about 20 minutes.
Day-of problems with your phone number or evidence: Allegheny County, 412-350-4636, Option 2. Disconnected and no callback within five minutes: Board Administrator, 412-350-4603.
Want us to handle the hearing? Call 412.802.6666.
Watch your mail. After the September 1 filing deadline, BPAAR schedules hearings and mails notices.
Check status anytime on the "Appeal Status" tab for your parcel on the Real Estate Portal.
Traveling? Have your mail forwarded or check status regularly. Notices can arrive while you are away.
Act before the hearing if you possibly can. Missing a hearing without a timely postponement is serious.
Call the County immediately at 412-350-4636, Option 2. If the hearing has already passed, ask the Board in writing for relief and explain, with documents, why you could not attend. Relief is not guaranteed.
We handle missed-hearing problems regularly. Call 412.802.6666.
Yes, once. Each party may request one postponement of a BPAAR hearing.
Emergency requests must also be in writing, cannot be sent by regular mail, and must be sent to all parties at the same time.
Choose your new date carefully. You will not get a second routine postponement.
If you have an attorney, your attorney can usually attend so that you do not need to postpone at all.
Bring evidence of value, not complaints about taxes. The Board will raise, lower or keep your assessment based on the evidence of value presented.
Check the other side's comparable sales for wrong prices, dates or square footage. You can verify them on the County's Real Estate Portal.
Want us to build your evidence? Call 412.802.6666.
No, an attorney is not required. An owner can handle a BPAAR appeal alone, or appoint an authorized representative. Whoever appears must follow the County's phone, evidence and authorization rules.
We review the numbers before we accept any appeal. If the savings will not justify the fee, we will tell you. Fees are discussed and agreed in writing before we file.

Yes, at the first level. At a BPAAR hearing, you may appoint an Authorized Representative to file the appeal and represent you, using the County's signed authorization form.
The form is the County's Appointment of Authorized Representative.
The second level is a formal proceeding in the Court of Common Pleas. In our view, only the owner or a Pennsylvania-licensed attorney should appear for the owner there.
Need someone to appear for you? Call 412.802.6666.
You are not required to attend, but you should take the appeal seriously. When a school district or municipality appeals, its goal is to raise your assessment, and the hearing goes forward whether or not you participate.
Read our guide to defending school district appeals.
Received a school district appeal notice? Call 412.802.6666.
Yes. Any party, including you, the school district, the municipality or the County, can appeal a BPAAR decision to the Court of Common Pleas, where it is heard by the Board of Viewers (BOV).
⚠️ Do not read "final" on a BPAAR notice as the end of the road. Check the mailing date and calendar the 30-day deadline immediately. See the County's Appealing a BPAAR Decision page.
Received a BPAAR decision? We will review it free: 412.802.6666.
The Board of Viewers (BOV) is the court-level stage of an Allegheny County assessment appeal. It hears appeals from BPAAR decisions filed in the Court of Common Pleas, and the outcome can affect several tax years.
⚠️ We strongly recommend counsel at this stage. In our view, only the owner or a Pennsylvania attorney should appear for the owner.
Facing a BOV appeal? Call 412.802.6666 or email Attorney Nicole Hauptman Amick at nicole@pghfirm.com.
