Allegheny County Homestead Exemption: Rules & Savings
The Allegheny County Homestead Exemption is officially called the Homestead/Farmstead Exclusion, Act 50. It reduces the assessed value of a qualifying owner-occupied primary residence by $18,000 for Allegheny County real estate tax purposes only, which Allegheny County lists as about $115.74 in annual county-tax savings for most property owners.
Applications are handled by the Allegheny County Office of Property Assessments. The application must be received by March 1 of the applicable tax year. If you already filed and still live in the same qualifying home, you generally do not need to file again; new owners, deed/name-change situations, trust transfers, and new primary residences need special attention.
What Is the Allegheny County Homestead Exemption?
Allegheny County’s homestead exemption is the Act 50 Homestead/Farmstead Exclusion. It gives qualifying owner-occupied primary residences a fixed assessed-value reduction for Allegheny County tax purposes. Qualification for Act 50 also connects to Pennsylvania Act 1 school property-tax relief where applicable, but the county Act 50 amount and school-district Act 1 relief are not the same line item.
Primary Residence Required
The home must be your primary residence or domicile. The application asks whether you use the property as your primary residence and whether you claim another place as your primary residence.
Useful proof: driver’s license, voter registration, income tax form, or local earned income tax form.
File With OPA
The Office of Property Assessments administers Act 50 applications. The County Treasurer handles county tax billing/payment and Act 77 senior relief, but homestead approval starts with OPA.
Correct office: OPA Legislative Acts, 542 Forbes Avenue, Room 347, Pittsburgh.
Check Status Online
After filing, use the Allegheny County real estate portal. The General Information tab should show “YES” on the Homestead line when the exclusion is applied for the visible current tax year.
Buyer warning: a “YES” after sale may belong to the prior owner.
Who Qualifies for the Allegheny County Homestead Exemption?
Act 50 is mainly for property owners whose Allegheny County property is their primary residence. The application is short, but the answers matter because false or outdated claims can lead to repayment, interest, penalties, and prosecution risk.
Core Requirements
- You are a recorded owner of the property.
- The property is your primary residence or domicile.
- You do not claim another property as your primary residence.
- The application is received by March 1 for the applicable tax year.
Information on the Application
- Parcel ID from the real estate tax bill or property record.
- Property address and mailing address.
- Owner name and phone/email contact information.
- Primary-residence and other-residence questions.
- Condo/co-op, rental, business-use, and farmstead questions if applicable.
Farmstead Rules
- Farmstead exclusion is separate from normal homestead use.
- Eligible farm buildings/structures must be tied to qualifying commercial agricultural activity.
- The farm must generally be at least ten contiguous acres and used as the owner’s domicile.
- Clean and Green or other abatement status may need review.
How to Apply for the Allegheny County Homestead Exemption
Use this workflow before submitting the Act 50 application. It prevents the most common Allegheny County mistakes: wrong parcel ID, prior-owner “YES” confusion, missed March 1 deadline, deed-name mismatch, trust transfer issues, and missing status verification.
Search the County Real Estate Record
Open the Allegheny County real estate portal and search by property address, owner name, or parcel ID. Confirm the owner name, parcel number, property address, municipality, school district, and current Homestead line before filing.
Confirm That the “YES” Is Yours
If the property had a recent sale or deed change, a “YES” on the Homestead line may apply to the prior owner. New owners who want the exclusion must apply in their own name.
Download the Act 50 Application
Use the County’s official Act 50 Application for Homestead & Farmstead Exclusions. Do not use an old third-party form unless the County confirms it is accepted for the current tax year.
Answer Primary-Residence Questions Carefully
The form asks whether the property is your primary residence, whether you claim another place as your primary residence, whether it is a co-op/condo with jointly paid taxes, and whether any part is used as business or rental property.
Submit by Email or Mail
Allegheny County’s 2026 Act 50 form allows submission by email to LegislativeActs@AlleghenyCounty.US, or by mail to Office of Property Assessments, 542 Forbes Avenue, Room 347, Pittsburgh, PA 15219, Attn: Legislative Acts.
Save Proof of Filing
Save the sent email, PDF copy, mail tracking, office receipt, or any confirmation. This is important if the Homestead line does not update or if OPA later requests proof.
Verify Status on the Real Estate Portal
The County instructions say the General Information tab will show “YES” in the Homestead line if the abatement has been applied to the current tax year shown on the site. Advance-year information may not appear before it becomes active.
Allegheny County Homestead Exemption Deadline
The Act 50 application must be received by March 1 of the applicable tax year. Assessment appeals, special appeals, Act 77 senior relief, Pennsylvania Property Tax/Rent Rebate, and tax-bill payment deadlines follow different calendars.

How Much Can the Allegheny County Homestead Exemption Save?
Act 50 reduces assessed value for Allegheny County tax purposes. It is not a direct rebate check, and it does not automatically eliminate municipal, school, or special-tax obligations. Your total property-tax relief can include multiple programs.
Act 50 County Exclusion
Allegheny County lists the Act 50 benefit as a $18,000 reduction in assessed value for county tax purposes only, resulting in about $115.74 in annual county-tax savings for most constituents.
Act 1 School Relief
Pennsylvania Act 1 school property-tax relief is handled through homestead/farmstead exclusions for school taxes. Allegheny County says qualification for Act 50 automatically activates Act 1 exclusion where applicable.
Act 77 Senior Tax Relief
Allegheny County’s Treasurer administers Act 77, which can provide a flat 30% discount on county real estate tax, up to a $650 annual reduction, for qualified seniors and other eligible residents.
PA Property Tax/Rent Rebate
Eligible Pennsylvania seniors, widows/widowers, and adults with disabilities may qualify for a separate state rebate on 2025 property taxes or rent paid, with a current 2026 filing deadline of December 31, 2026.

Allegheny County Homestead Savings Estimator
This calculator is for education only. It estimates the county Act 50 savings from an assessed-value reduction and can optionally show a rough senior discount scenario. Actual tax bills depend on certified assessments, millage, school/municipal bills, Act 1 relief, Act 77 approval, exemptions, and payment timing.
Estimate logic: Act 50 uses an $18,000 county assessed-value reduction multiplied by county millage divided by 1,000. The default 6.43 millage produces $115.74. Act 77 senior relief is modeled as 30% of entered county tax, capped at $650. School relief must be entered separately because Act 1 amounts vary by school district.
Find Your Allegheny County Property Record Before Filing
The Allegheny County real estate portal is the fastest way to confirm parcel ID, owner name, property address, school district, tax code, assessed value, sale information, and whether the Homestead line already shows “YES.”
Search by Address
Start with the street address. If the portal does not find the property, remove punctuation, unit details, street suffixes, or ZIP code, then search again.
Search by Owner
Use owner search after deed processing. If you bought recently, the record may still show the seller or may show a prior-owner homestead status until the sale is fully processed.
Use Parcel ID
The Act 50 application asks for Parcel ID. Copy it from the County real estate portal or a real estate tax bill rather than guessing from a closing document.
OPA vs Treasurer vs School District: Who Handles What?
Allegheny County property-tax questions are split between multiple offices. The Office of Property Assessments handles assessment records and Act 50; the Treasurer handles county tax billing/payment and Act 77; school districts and local tax collectors handle local school/municipal billing details.

Common Allegheny County Homestead Exemption Mistakes
These mistakes can cause lost savings, delayed approval, wrong-office confusion, or repayment exposure if a homeowner keeps the exclusion after the property no longer qualifies.
Assuming Act 50 Covers Every Tax
Act 50’s county benefit is for Allegheny County tax purposes only. School and municipal relief must be checked separately on the appropriate bill.
Missing March 1
The Act 50 application must be received by March 1 of the applicable tax year. Waiting for the tax bill can be too late.
Relying on the Seller’s “YES”
If a recent sale or deed change occurred, the Homestead “YES” may apply to the prior owner. New owners must apply.
Not Reapplying After Deed or Trust Change
Name changes, deed changes, transfers into a trust, or a new primary residence can require a new application or OPA review.
Not Reporting Change in Use
If a property no longer qualifies as homestead or farmstead, owners must notify the assessor within 45 days of the change in use.
Missing the Special Appeal Window
If OPA denies or changes a Homestead/Farmstead determination, a Special Appeal must generally be filed within 30 days from the official mail date on the notice.
What Should You Do Next?
Choose the path that matches your Allegheny County situation today.
If you never filed Act 50
Search your property record, copy the Parcel ID, complete the official Act 50 application, and email or mail it to OPA Legislative Acts before March 1 for the applicable tax year.
If the portal already says “Homestead: YES”
Confirm the “YES” belongs to your ownership, not a prior owner. If you recently bought the property, changed title, or transferred the deed, contact OPA before relying on it.
If you are a senior, disabled, or widow/widower
Review Act 77 with the Allegheny County Treasurer and the Pennsylvania Property Tax/Rent Rebate with the Department of Revenue. These are separate from Act 50 and can have different income and filing rules.
If your application was denied
Read the OPA denial or determination letter, gather proof of primary residence, then review the Special Appeals process. The appeal generally requires the determination letter and must be filed within the stated deadline.
