Allegheny County Homestead Exemption Guide

Can I get the Allegheny County homestead exemption?

Maybe. In Allegheny County, the main homestead benefit is officially called the Homestead/Farmstead Exclusion, Act 50.

It is for qualifying owner-occupied primary residences. Allegheny County says the Act 50 exclusion reduces the assessed value used for county real estate tax by $18,000. The county also says qualification for Act 50 automatically activates the Act 1 exclusion for school taxes. You do not file a separate county homestead application for Act 1.

The usual filing deadline is March 1. The official application says applications must be received by March 1 of the applicable tax year.

Start with the county, not a paid filing website. Use the official Allegheny County Homestead/Farmstead Exclusion page and the county’s Act 50 application.

What Allegheny County means by “homestead exemption”

Pennsylvania often uses the term homestead/farmstead exclusion instead of only “homestead exemption.” In Allegheny County, the county page names the program Homestead/Farmstead Exclusion (Act 50).

The word “exclusion” matters. The county does not remove your whole home from taxation. Instead, it excludes a set amount of assessed value before the tax is calculated. For Allegheny County Act 50, the county states that the first $18,000 in assessed value is excluded from county real property taxation.

This guide is limited to the homestead/farmstead exclusion question. It is not a general property tax relief guide. It does not cover unrelated rebates, deferrals, postponements, or broad tax programs.

Who may qualify

The core rule is simple, but the details can matter. Allegheny County says only primary residences qualify. A homeowner can have only one homestead exclusion.

Common qualifying situations may include an owner-occupied residential home, certain farmstead property, a property in a trust that is still used as a primary residence for an individual, and mixed residential and business property where the owner lives in part of the property. The county page also lists a church rectory or manse that is a primary residence and property owned by honorably discharged wartime veterans with a 100% service-connected disability among properties that may qualify.

Do not assume approval just because you live in the home. The county can look at ownership, deed records, primary residence facts, other residences, mixed use, and whether the form is complete.

One-home rule: The Act 50 application asks whether you use the property as your primary residence and whether you claim anywhere else as your primary residence. If you have another home, recently moved, or live part of the year somewhere else, answer carefully and contact the county if you are unsure.

Where to start

For Allegheny County Act 50, the starting office is the Office of Property Assessments. The county’s official page tells homeowners to download and complete the Act 50 application.

Basic application steps

  1. Find your parcel ID on your real estate tax bill or through the county property record search.
  2. Download the official Act 50 application form.
  3. Fill in the parcel number, property address, owner name, mailing address, phone number, and email address.
  4. Answer the primary residence, other residence, condominium/cooperative, business or rental use, and farmstead questions.
  5. Sign and date the form.
  6. Submit it by email or mail using the official instructions on the form.

Official county filing information

The Act 50 application lists the Office of Property Assessments address as:

Office of Property Assessments
542 Forbes Ave., Room 347
Pittsburgh, PA 15219
Attn: Legislative Acts

The same application says a signed, completed form may be submitted by email to LegislativeActs@AlleghenyCounty.US. It also lists the county assessment office phone number as 412-350-4636.

What information the application asks for

The form is short, but it asks questions that can affect approval. You should be ready with:

  • Your parcel ID.
  • The property address.
  • The name of each owner of record.
  • Your mailing address, even if it is the same as the property address.
  • A phone number and email address so the county can contact you about questions.
  • Whether the home is your primary residence.
  • Whether you claim another place as your primary residence.
  • Whether the property is a condominium or cooperative where taxes are paid jointly.
  • Whether part of the property is used for a business or rental purpose.
  • Whether you are also seeking a farmstead exclusion.

The official instructions say you may be asked for proof that the property is your residence. Examples listed by the county include a driver’s license, voter registration card, personal income tax form, or local earned income tax form.

Deadline and timing

The county page says the application must be submitted by March 1 for the exclusion to be in effect for the current and future tax years. The current county application says applications must be received by March 1 of the applicable tax year.

The Pennsylvania Department of Community and Economic Development also explains that homestead or farmstead exclusion applications for school property tax relief must be filed by the preceding March 1. That deadline is set by state law.

If you are close to the deadline, do not wait until the last mailing day. Use the official county instructions and keep a copy of what you send.

If March 1 already passed: Still contact the Office of Property Assessments. Ask whether your application can be accepted for a future year and whether any notice or appeal rights apply to your situation. Do not assume a late application will apply to the current year.

How Act 50 relates to school taxes

Allegheny County’s Act 50 page says the county program is for Allegheny County tax purposes only. The same page also says that qualification for Act 50 automatically activates the Act 1 exclusion for school taxes and that no additional application is required.

This can confuse homeowners. The county decides whether your property is approved for the homestead/farmstead status. School districts may use the approved homestead list for school tax bills. School tax amounts and district participation questions are not the same as the county Act 50 amount. If you need school bill details, check with the school district or the tax office shown on your bill.

The safest way to think about it is this: apply through Allegheny County for the homestead/farmstead status, then verify how that status appears on the county property record and on later tax bills.

How to check whether you already have it

You may not need to file again. Allegheny County says property owners who already filed for the Act 50 exclusion do not need to re-file in later years.

To check, use the official Allegheny County real estate portal. The county says the property’s General Information tab will show “Yes” in the Homestead line if the application is on file. The application instructions also warn that advance information will not be shown.

If the portal does not show what you expected, contact the Office of Property Assessments before filing a duplicate form or assuming you were denied.

When you may need to reapply or update the county

The county says you do not have to reapply every year once you have filed. But some changes can require a new application or notice to the county.

Allegheny County specifically says to reapply if there is a name change to a deed, such as a transfer to a maiden name, or if a deed places the property into a trust. The county also says to reapply if you have a new primary residence within Allegheny County.

The application instructions also say that when the use of an approved homestead or farmstead property changes so that it no longer qualifies, the property owner must notify the assessor within 45 days of the change in use.

Recently moved

If you bought a new home or moved from one Allegheny County home to another, do not assume the old approval follows you. The county says the exclusion is removed automatically when a property sale is processed through the Division of Real Estate, effective January 1 of the calendar year following the recorded sale. A new primary residence may require a new application.

Trusts, divorce, death, or inherited homes

Trusts and title changes can affect the homestead record. The county says property in a trust may qualify if it is still used as a primary residence for an individual, but it also says to reapply when a deed enters a property into a trust.

If the homeowner died, a spouse remained in the home, a divorce changed title, or you inherited the home, check the deed and the county record before assuming the exemption is still correct. The application instructions say owners of record must apply. If your name is not recorded as an owner, ask the Office of Property Assessments what it needs. For legal title questions, consider getting legal advice from a qualified professional.

Farmstead exclusion basics

The same Allegheny County application covers homestead and farmstead exclusions. Most ordinary homeowners only need the homestead part.

The official instructions say only buildings and structures on farms that are at least ten contiguous acres and used as the owner’s primary residence are eligible for a farmstead exclusion. The instructions also say the buildings and structures must be used for commercial agricultural production, such as storing farm products, housing animals, or storing agricultural supplies, machinery, and equipment.

If your property is not a working farm, do not check farmstead just because you have a large yard, garden, shed, or outbuilding. Ask the county if you are unsure.

What can go wrong

Most problems come from timing, ownership, or primary residence facts. Common issues include:

  • The application was received after March 1.
  • The applicant is not listed as an owner of record.
  • The property is not the owner’s primary residence.
  • The owner claims another home as a primary residence.
  • The home was sold, transferred, placed into a trust, or retitled.
  • Part of the property is used as a rental or business and the form does not explain the residential portion.
  • The county requested proof of residence and did not receive enough information.
  • The homeowner assumed a prior owner’s approval would stay with the property.

False application warning: The county application warns that a knowingly false application can lead to taxes due, interest, penalties, and possible prosecution. The county page also warns that a person with more than one homestead exclusion may face interest, penalties, and fines up to $2,500.

If your application is denied

The county application says that if your application is denied, you will receive written notice of the denial at the mailing address you provided.

Allegheny County says a Homestead/Farmstead Act 50 determination is appealable by Special Appeal. The county’s Special Appeals page says a completed Special Appeals form must be sent within 30 days from the official mail date on the notice. It also says the appeal must be mailed or hand-delivered, cannot be faxed or emailed, has no filing fee, and must include a copy of the determination letter or notice.

If you receive a denial, read the notice right away. Do not wait until the 30 days are almost over. If the problem is ownership, a trust, death, divorce, or another legal issue, you may need legal advice in addition to contacting the county.

Be careful with paid filing-service content

You do not need to start with a private website that charges a fee to explain or submit the Allegheny County Act 50 form. The official county form is available from Allegheny County, and the filing instructions are on the form.

Be careful with any website or mailer that makes the exemption sound automatic, urgent in a misleading way, or connected to the government when it is not. HomesteadExemption.org does not file the application for you and is not connected to Allegheny County.

This is not bankruptcy homestead protection

The Allegheny County Homestead/Farmstead Exclusion is a property tax assessment exclusion. It is not the same thing as homestead protection in bankruptcy, creditor protection, estate planning, or foreclosure law.

If your concern is bankruptcy, debt collection, a sheriff sale, estate administration, or whether a creditor can reach your home, this county tax exclusion guide is not enough. You should speak with a qualified legal professional or legal aid organization.
