What is the Ohio property tax assessment ratio?

Ohio law sets taxable value at 35% of market (true) value statewide, under Ohio Revised Code §5713.03. Your county auditor must use this ratio when calculating your tax bill.

How much is the Ohio Homestead Reduction in 2026?

For tax year 2026, the general Homestead Reduction shields $29,000 of market value for qualifying owners age 65+, totally disabled, or surviving spouses age 59+ with Ohio Adjusted Gross Income under $41,000. The enhanced amount for 100% disabled veterans and surviving spouses of public-safety officers killed in the line of duty is $58,000 with no income limit. File DTE Form 105A with your county auditor.

When is the Ohio Board of Revision deadline?

Ohio's statutory Board of Revision (BOR) complaint deadline is March 31 for the prior tax year, per ORC §5715.19. Complaints are filed using DTE Form 1 with your county auditor at no cost. Late filings are rejected except in very narrow clerical-error circumstances.

How much is the Ohio real property conveyance fee?

Ohio's conveyance fee has two parts: a mandatory $1.00 per $1,000 state fee (ORC §319.54(F)(3)) and a permissive county levy of up to $3.00 per $1,000 (ORC §322.02). Most Ohio counties charge the full $4.00 per $1,000. A separate $0.50 transfer fee applies per parcel. Filed using DTE Form 100 at the auditor's office at closing.

Who qualifies for Ohio's CAUV agricultural tax break?

Ohio's Current Agricultural Use Value (CAUV) program lets actively farmed land be taxed on its agricultural value rather than its market value. Eligibility requires 10+ acres devoted exclusively to commercial agriculture, or smaller parcels with $2,500+ in gross annual income from agriculture. Apply using DTE Form 109 and renew annually with DTE 109A. Removing land from CAUV triggers recoupment of three years of saved taxes under ORC §5713.34.

Quick answer: start with the Real Estate Portal

Search by address or parcel number, open the matching property, verify its block-and-lot ID, then review the General Information, Building, Tax, Owner History, Appeals and Map sections before moving to another county office.

1 Search simply Use a house number and street name or parcel ID.

2 Verify the municipality Pittsburgh mailing addresses can cover different municipalities.

3 Save the parcel ID Use it for tax, GIS, deed and appeal work.

Pennsylvania assessment method

Why Allegheny County uses a 2012 base-year value

Allegheny County uses a base-year methodology with an effective valuation date of January 1, 2012. The countywide reassessment based on that year was first used for the 2013 tax year.

When the county may change a value

Omitted property or improvement

Mathematical or clerical error

New construction or addition

Building demolition

Subdivision or parcel change

Municipal building or occupancy permit

Successful annual or special appeal

Qualifying catastrophic loss

Permit effect: Municipalities submit building, demolition and occupancy permits to the Office of Property Assessments. A permit can lead to a review and an interim assessment.

Catastrophic-loss relief

A property damaged by fire or another qualifying catastrophic event may be eligible for a proportional assessment reduction. The application must generally be filed within six months of the loss.

Date and cause of loss

Fire, insurance or inspection report

Photographs of damage

Repair or demolition estimates

Parcel ID and owner information

Current occupancy status

Read assessment methodology Review permit assessments

Notice-based appeals

Use a Special Appeal after a written determination

A Special Appeal is different from the annual appeal window. It may be filed year-round after certain written county determinations.

Determinations that may support a Special Appeal
Determination	Typical deadline	Required preparation
Assessment Change Notice	Within 30 days of the official mail date	Attach the notice and value evidence.
Catastrophic Loss	Follow the determination notice	Damage, timing and condition evidence.
Clean and Green	Within 30 days of the determination	Use, acreage and programme documents.
Homestead/Farmstead	Within 30 days of the determination	Residency, ownership and application evidence.
Exempt status	Within 30 days of the determination	Ownership, use and exemption documents.
Interim assessment or LERTA	Within 30 days of the notice	Permit, construction, abatement and value records.

Submission rule: The county says a Special Appeal must be mailed or hand-delivered. It cannot be faxed or emailed, and the written determination must be attached.

Allegheny County assessment-relief programmes
Programme	Main benefit	Published deadline	Important rule
Homestead/Farmstead Act 50	$18,000 reduction in county taxable assessed value.	March 1	Must be the qualifying owner’s primary residence.
Clean and Green Act 156	Preferential assessment for qualifying agricultural, reserve or forest land.	June 1 for the following tax year	Approved applications require recording and a recording fee.
Nonprofit or governmental exemption	Full or partial real-estate tax exemption where qualifications are met.	March 31 for the same tax year	Property generally must be owned on January 1.
Catastrophic loss	Possible proportional assessment reduction after qualifying damage.	Within six months of loss	Document the cause, date and extent of damage.

Homestead/Farmstead Act 50

The county exclusion removes the first $18,000 of qualifying assessed value from Allegheny County real-property taxation. At the published 6.43-mill county rate, the county illustrates annual savings of $115.74 for most qualifying parcels.

Confirm primary residence A homeowner can receive only one qualifying Homestead exclusion.

Check the parcel status Open General Information and look for “Yes” beside Homestead.

Apply by March 1 Applications received by the deadline can apply to the current and future tax years.

Reapply after a qualifying ownership change A new deed, trust transfer or new primary residence can require a new application.

Review the next bill Confirm that the exclusion appears for the current owner—not only the former owner.

Recent-sale warning: A “Yes” shown on the parcel shortly after a deed transfer may belong to the previous owner. New owners must apply for their own exclusion.

The June 1, 2026 deadline for preferential treatment in the following calendar tax year has passed. Property owners should prepare acreage, land-use and programme documents early for the next available filing cycle.

Ten practical answers

Allegheny County property and tax FAQs

Is Allegheny County located in Ohio?

No. Allegheny County is located in Pennsylvania. Property assessments are handled by the Allegheny County Office of Property Assessments rather than an Ohio-style County Auditor.

How do I search Allegheny County property records?

Use the official Allegheny County Real Estate Portal. Search by property address or parcel number, open the matching parcel and verify the physical address, municipality and block-and-lot parcel ID.

Can I search Allegheny County property by owner name?

The free public portal primarily supports address and parcel-number searches. Owner-name searching is offered through the county’s subscription real-estate service. The current owner is displayed after a public parcel is opened.

Why should I omit the street suffix in an Allegheny County search?

The official portal instructs users not to include suffixes such as Street, Drive or Circle. Enter the house number and main street name, and leave the municipality blank when it is uncertain.

What is Allegheny County’s current assessment base year?

Allegheny County uses 2012 as its base year, with an effective valuation date of January 1, 2012. The last countywide reassessment was used for the 2013 tax year.

What is the deadline for a 2027 Allegheny County assessment appeal?

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

What should I do if my 2026 Allegheny County tax is unpaid?

The March 31 net-tax and April 30 gross-tax dates have passed. Open the parcel’s Tax Information tab to view the live amount, penalty and interest, or call the Treasurer at 412-350-4100 before paying.

How do I find an Allegheny County deed or mortgage?

Use the Allegheny County land-record databases or contact the Division of Real Estate. Parcel pages provide deed-book and deed-page clues, but a complete ownership or lien search requires the recorded documents.

Are Allegheny County GIS parcel lines legal boundaries?

No. GIS parcel lines are useful for property-location and research purposes but do not replace a recorded deed, subdivision plan, legal description or professional boundary survey.

How does the Allegheny County Homestead Exclusion work?

Qualifying owner-occupied primary residences can receive an $18,000 reduction in assessed value for county-tax purposes. Applications are generally due by March 1, and a new owner must submit a new application.

Information checked August 7, 2026: Property-search rules, assessment methodology, annual and special appeals, tax dates, payment guidance, Homestead, Clean and Green, GIS, address changes, deed requirements and office contacts were checked against official Allegheny County sources.

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.
