Your question
Correct office or tool
What it provides
Important limitation
Who owns the parcel and what is its value?
Auditor property search
Owner display, parcel number, values, land, buildings, sales, tax district and reductions.
The result is not a title opinion.
What amount must I pay?
County Treasurer
Current bill, payment, posting, delinquency and payment-plan help.
The Auditor does not process the payment.
Where is the parcel?
Auditor Map / GIS
Map location, nearby parcels, roads and general geographic context.
Parcel lines are not surveyed boundaries.
What is the legal description?
Tax Map Office
Description review, land-title research, plats and historical maps.
A tax map does not replace a survey.
Where is the deed or mortgage?
County Recorder
Recorded deeds, mortgages, liens, releases, easements and document copies.
A name search is not a complete title examination.
Can I split or develop the property?
Tax Map, Engineer and Building Department
Transfer review, subdivision, building, floodplain and access routing.
Auditor ownership data is not development approval.
Is the market value wrong?
Auditor and Board of Revision
Informal review followed by the formal DTE Form 1 process.
The Board reviews value, not voter-approved tax rates.
Does farmland qualify for CAUV?
Auditor Farm Programs
Initial application, annual renewal and recoupment guidance.
Ownership of rural land alone does not create eligibility.
Best sequence: Auditor search → verify parcel number → review the complete property record → use the Treasurer for money, Recorder for documents or Tax Map for legal-description and boundary research.
Search troubleshooting

No parcel result? Use this recovery sequence

Owner search failed Use the surname alone, then try a prior owner, trust, estate, farm or business name.
Address search failed Remove the direction and street type. Search with only the house number and main street word.
Rural property is missing Search the owner or parcel number and use the map rather than relying on the postal address.
Recent purchase shows the seller Search the previous owner and check the Recorder’s index for the newly recorded deed.
New lot or parcel split Search the parent parcel, original acreage owner or developer.
Two parcels were combined Search each old parcel number and ask Real Estate Transfers whether a combination was processed.
Vacant property has no street number Use owner, parcel, township, tax district or map-based research.
Manufactured home is missing Confirm registration, title status and whether the home is taxed as real property or a manufactured home.

Prepare before calling the Auditor

Late-payment consequences

First ten days after the deadline

The published penalty is 5% of the unpaid second-half amount.

After the first ten days

Possible inflation-cap adjustment

The Auditor has posted a notice that recent legislation created an inflation cap affecting certain property-value increases. Eligible parcels may receive an adjustment on the second-half bill. Not every parcel qualifies.

Compare the first- and second-half amounts An eligible parcel may show a change that was not available for the first-half bill.

Do not estimate eligibility yourself Use the actual tax bill and contact the Auditor for value-adjustment questions.

Treasurer call script “I am calling about parcel [parcel number] at [address]. Can you confirm the amount due for August 14, whether an inflation-cap credit or overpayment appears, whether my payment has posted, and the least expensive accepted payment method?”
Comparable-sales research

Use the Sales Report without choosing misleading comps

The official Sales Report can summarize transactions by price range and display average, median, minimum, maximum, sale count and parcel count. It also provides a CSV export for deeper review.

Build a useful comparable-sales set

Match location
  • Same township or corporation
  • Same or similar school district
  • Similar neighborhood
  • Comparable road, access and utility context
Match property
  • Similar land use
  • Similar acreage
  • Similar year built and living area
  • Similar grade, condition and outbuildings
Match transaction
  • Recent sale date
  • Valid-sale indicator
  • Normal market exposure
  • No family, estate or multi-parcel distortion

Transfers that may not show market value

Family or related-party transfer
Trust or estate transfer
Quitclaim deed
Sheriff or foreclosure deed
Several parcels sold together
Partial ownership interest
Property with major condition differences
Sale too remote from the value date
Rural-property tip: Compare agricultural use, CAUV status, acreage, timber, homesite, barns, road frontage and utilities before treating one farm sale as comparable to another.
GIS, plats and historical maps

Use the map for location—not legal boundary proof

Find the parcel number first A parcel identifier is often more reliable than a rural mailing address.
Open the Auditor Map Search or navigate to the parcel and click the mapped shape.
Compare the parcel result Match the parcel number with the Auditor property record.
Review neighboring parcels Use the map for general adjacency, road and parcel-shape context.
Contact Tax Map for description research Provide the parcel number, map number, deed reference and purpose.
Obtain a survey when exact lines matter A GIS or hard-copy tax plat is not a professional boundary survey.

How do I search by owner name in Washington County?

Enter the name in Last First format. Start with the surname only, then add the first name if too many matches appear. For a trust, estate, farm or company, begin with the most distinctive word.

What are the Washington County online tax-payment fees?

Online credit and debit card payments carry a 2.4% convenience fee with a $2 minimum. Online electronic checks carry a flat $1 fee. Limits and parcel-count restrictions apply.

Can Washington County GIS parcel lines prove a legal boundary?

No. Washington County states that GIS and hard-copy plat maps are representative drawings for tax purposes and are not official records or survey plats. Use a deed, recorded survey and professional surveyor when exact boundaries matter.

Where can I search Washington County deeds and mortgages?

Use the Washington County Recorder’s official online records search. Quick Search accepts a grantor, grantee, subdivision, document type or document number, while Advanced Search provides additional filters.

How much is the Washington County conveyance fee?

What are the Washington County CAUV requirements?

A tract of at least 10 acres used for commercial agriculture during the previous three years may qualify. A smaller tract may qualify through the $2,500 agricultural-income route. The initial fee is $25 and renewal is required annually.

How are manufactured homes handled in Washington County?

Verify with the official Ohio source

These calculators use the verified 2026 Ohio Department of Taxation amounts and statutory rules. For your exact bill, exemption status, and county-specific deadlines, always confirm with your county auditor and the Ohio Revised Code:

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. Nothing here is legal or tax advice. CountyAuditors.org is an independent informational directory, not affiliated with any county government.
