Knox County Auditor, OH: Property Search, Records (2026)

How to Search Knox County Auditor Property Records

The Auditor’s real estate search is the starting point when you need an owner name, parcel identification number, property address, appraisal information, sale history or available tax details.

Knox County has introduced an upgraded real estate search experience. Start from the official Auditor homepage and choose Real Estate Search or the Search option in the navigation. The county also links to its Beacon property-search service.

Search by property address

1. Open the official property-search portal.

   Visit the county Auditor website and select its current real estate search link.

2. Choose the address search field.

   Enter the house number and street name. For example, a search for a Mount Vernon property may work better without the ZIP code or street suffix.

3. Review matching addresses.

   Check the street name, municipality or township and other identifiers before choosing a result.

4. Open the full property record.

   Select the matching parcel to review its owner, parcel number, property description, value and available map or tax information.

5. Save the parcel number.

   Use this number when contacting the Auditor, Treasurer, Recorder or GIS department about the same property.

Search by owner name

If you know who owns the property but not its location, try the surname first. For a company, use the distinctive portion of its registered name.

When several names match, compare addresses and parcel numbers. Trusts, estates and business entities may appear under legal names that differ from the names commonly used by residents.

Search by parcel number

A parcel number is usually the most precise way to identify land. Copy it from a previous tax bill, deed-related paperwork or another official county record.

1. Open the property-search service.
2. Select the parcel or property ID search option.
3. Enter the number in the format accepted by the system.
4. Open the matching record and confirm the location.
5. Keep the parcel number for future property-tax and recording questions.

What if the search returns no property?

Try removing punctuation, apartment information, directional abbreviations or extra words. Vacant land may not have a conventional street address, so use the owner’s name, parcel number or map instead.

If the record remains missing, contact the Auditor’s real estate department at 740-393-6745.

What a Knox County Property Record Actually Tells You

Finding the correct parcel is only the first step. The information inside the record can help you understand ownership, assessed value, building details and potential tax questions.

Market value is not the amount of tax you owe

Ohio generally calculates taxable assessed value at 35% of the property’s appraised market value.

For example, a home with an appraised value of $240,000 would have an assessed value of approximately $84,000 before applicable adjustments.

That $84,000 is not the property-tax bill. Taxing district rates, credits, reduction factors and special assessments affect the actual amount payable.

Knox County GIS Maps, Tax Maps and Property Boundaries

GIS mapping is especially useful for vacant land, adjoining parcels, acreage questions and properties with confusing addresses.

Knox County’s Tax Map Office also assists with land descriptions, subdivision information, survey drawings and mapping records. It works near the Auditor and Recorder offices in Mount Vernon.

Find a parcel on a county map

1. Find the correct parcel record.

   Search the Auditor’s real estate system and copy the parcel number.

2. Open the official mapping resources.

   Visit Knox County Tax Map & GIS.

3. Select the appropriate map or GIS resource.

   Search by parcel identification or property location where the linked system supports those options.

4. Inspect surrounding properties.

   Compare nearby parcels, roads, approximate boundaries and mapped features.

5. Request supporting documents if needed.

   For surveys, plats, older maps or land descriptions, use the resources listed by the Tax Map Office.

Official GIS and map-copy prices

Knox County publishes the following prices for map services:

The county states a 24-hour processing time for custom maps. Its posted electronic-payment service fee is 2.4% with a $2 minimum. Call 740-393-6754 to arrange payment and confirm the current total.

Knox County Property Taxes, Due Dates and Payments

The County Auditor maintains valuation and property information. The Knox County Treasurer handles property-tax collection, bills, payments and delinquency questions.

Published 2026 property-tax due dates

These are dates displayed on the official Auditor website when this guide was reviewed. They have passed as of October 29, 2026. Check the Treasurer’s current notices for outstanding balances, penalties and future installments.

How to check or pay property taxes

1. Find your parcel.

   Use the Auditor property search and confirm the correct parcel number.

2. Open the county tax-payment information.

   Use the official Knox County government website to locate the Treasurer, or follow the Treasurer payment link displayed on the Auditor homepage.

3. Verify the tax year and installment.

   Check the property identity, current amount due, any penalties and available payment history.

4. Choose the supported payment method.

   Review any card or electronic-service charge before completing payment.

5. Keep the confirmation.

   Save the receipt or transaction number. Check the account again if the payment does not appear after processing.

Why did my property tax increase?

A higher bill can result from a valuation change, a tax-rate change, a new levy, an adjustment to a credit or exemption, or an added assessment.

Compare both years’ property-tax information before assuming the Auditor made a valuation error. A value appeal does not automatically remove penalties or suspend a tax-payment obligation.

How to Challenge a Knox County Property Valuation

If you believe the county’s value is higher than the property’s supportable market value, the Knox County Board of Revision provides a formal valuation complaint process.

The county uses DTE Form 1 — Complaint Against the Valuation of Real Property. Its official Board of Revision page also provides procedural rules.

Knox County Board of Revision filing period

The regular filing window is January 1 through March 31. The county’s published notice identifies January 1–March 31, 2027 as the complaint period for tax year 2026 valuations.

1. Review the valuation first.

   Find the parcel, note the tax year and record the county’s current appraised value.

2. Decide what value the evidence supports.

   A complaint should identify the valuation issue and the requested correction, not just say that taxes are too high.

3. Gather supporting evidence.

   Relevant material may include a recent arm’s-length sale, professional appraisal, comparable sales, dated photographs, damage documentation or repair estimates.

4. Download the official complaint form.

   Open the Knox County Board of Revision page and select DTE Form 1 and the current procedural rules.

5. Complete and submit the complaint.

   Follow the form’s signature, supporting-document and filing instructions. Confirm acceptable delivery methods before the deadline.

6. Keep evidence of filing.

   Save a complete copy and proof of receipt. Be ready to respond to notices or attend a scheduled hearing.

What evidence is useful?

A Board of Revision complaint is a legal valuation procedure. Check its current rules, especially if you are filing for a business, trust or another legal entity.

Knox County Homestead Exemption and Owner-Occupancy Reduction

Homeowners should check whether they qualify for property-tax reductions before assuming the full amount on a bill is unavoidable.

Homestead exemption

Ohio’s Homestead Exemption can provide property-tax relief for eligible homeowners, including qualifying older adults, people with permanent and total disabilities, certain disabled veterans and qualifying surviving spouses.

The standard means-tested program generally applies an income limit to new participants, with exceptions and separate categories under Ohio law.

The Knox County Auditor’s published information lists a $41,000 Ohio adjusted gross income limit for tax year 2026 for the standard means-tested program. Income rules, eligibility categories and applicable tax years should be checked against current program guidance.

How to apply

1. Identify your eligibility category.

   Determine whether you are applying based on age, qualifying disability, veteran status or surviving-spouse eligibility.

2. Open the county Homestead page.

   Visit Knox County Homestead Exemption.

3. Choose the correct application.

   Use DTE 105A for applicable standard applications, DTE 105I for qualifying disabled veterans and surviving spouses, or DTE 105K for the applicable line-of-duty survivor category.

4. Prepare required documentation.

   Depending on the category, you may need ownership and residency information, proof of age, income information, disability certification or veteran-related documentation.

5. Submit the completed form.

   Follow the county’s filing requirements and confirm the current deadline and whether further verification is required.

Owner-occupancy reduction

The owner-occupancy reduction is a separate Ohio property-tax benefit for qualifying owner-occupied homes. It is commonly described as the 2.5% owner-occupancy reduction, although the actual benefit depends on the applicable tax calculation.

Use DTE 105C, available through the official Knox County forms page, to review the application.

Knox County CAUV: Agricultural Property Tax Valuation

Current Agricultural Use Valuation, or CAUV, allows qualifying farmland to be valued according to its agricultural use instead of its full development-market potential.

This program matters for Knox County farm owners because land value can be very different from its agricultural productivity value.

Who may qualify?

According to the Knox County Auditor, qualifying agricultural land must generally have been devoted to agricultural use for the three calendar years before the application year and satisfy an applicable statutory criterion.

• Land totaling at least 10 acres devoted to qualifying agricultural use.
• Smaller qualifying acreage meeting the applicable $2,500 average yearly gross agricultural income test or accepted anticipated-income requirements.
• Land qualifying under an applicable federal land-retirement or conservation-program provision.

The county lists a $25 initial application fee and states that renewal applications are due by the first Monday in March each year.

How to apply or renew CAUV

1. Check the parcel’s acreage, agricultural use and eligibility history.
2. Open the official Knox County CAUV page.
3. Use DTE 109 for an initial application or DTE 109A for renewal as applicable.
4. Prepare accurate land-use, acreage and agricultural income information.
5. Confirm the required filing fee, supporting documentation and current deadline.
6. Submit the form to the Auditor and keep the county’s acknowledgement.

What happens when farmland leaves CAUV?

Conversion from qualifying agricultural use can trigger a recoupment charge. Knox County describes the charge as the amount of agricultural valuation tax savings for the converted land during the previous three years.

Before splitting, selling, developing or changing farmland use, ask the farm program department how the proposed action may affect CAUV status and recoupment.

Farm program telephone: 740-393-6748.

Knox County Property Transfers, Conveyance Fees and Deed Records

A property transfer typically involves the Auditor’s conveyance process and the Recorder’s recording process. They serve different purposes, and completing one does not necessarily complete the other.

Current county conveyance fee

The Knox County Auditor publishes a real-property conveyance fee of $3 per $1,000 of sale price.

These are illustrations of the stated rate, not closing-cost quotations. Other transfer, recording, service or special fees may apply. Exempt transactions can follow different procedures.

Prepare a transfer

1. Verify the correct parcel numbers and legal descriptions.
2. Prepare the deed or other valid transfer instrument.
3. Complete the applicable conveyance statement, commonly DTE 100, or an exemption statement such as DTE 100(EX) when appropriate.
4. For qualifying Homestead or CAUV transfers, review DTE 101 or DTE 102 where required.
5. Check whether the Tax Map Office must review the legal description or a proposed split.
6. Confirm current fees and payment arrangements with the county.
7. Complete the Auditor’s transfer procedure and the Recorder’s separate recording requirements.

Where can I get a copy of a deed?

The County Recorder, rather than the Auditor, maintains recorded deeds, mortgages and related instruments. Start with the Knox County government directory to locate the Recorder’s current recording-search and copy-request services.

Use the parcel number, legal owner and approximate recording date to make document research easier.

Official Knox County Auditor Forms and Property Corrections

The Auditor maintains a useful collection of state and county forms. Here are the documents most likely to help with common property questions.

View and download official Knox County Auditor forms.

What if the property record contains an error?

Knox County also publishes a Property Data Correction Form. This is helpful when factual characteristics shown in the parcel record appear incorrect.

1. Locate the exact parcel and save the parcel number.
2. Write down the incorrect field and the information you believe is correct.
3. Gather supporting photographs, plans, surveys or relevant documents.
4. Download the Property Data Correction Form from the county’s forms page.
5. Contact the Real Estate department about the correct submission process.

Correcting property data and formally appealing a valuation are separate processes. If both issues apply, ask whether you should pursue both procedures.

Knox County Dog Licenses and Other Auditor Licenses

Dog license fees

The county publishes these dog license fees, effective December 1, 2024:

The standard annual renewal period is December 1 through January 31, with the county allowing the next business day when January 31 falls on a weekend. Late renewal may incur a penalty equal to the license cost.
