Knox County Auditor Help: Use the Correct Page for Property Records, Maps, Taxes and Forms

Most users searching for the Knox County Auditor want property records, parcel maps, tax-payment help, valuation appeal instructions, Homestead Exemption forms, CAUV help, dog licensing, or deed-copy guidance. The fastest path is to match the task with the correct office.

If you need owner details, parcel number, property value, tax tab, historical tax amounts, manufactured home search, tax estimator or GIS/Tax Map access, start with the Knox County Auditor website.

If you need tax bill due dates, payment status or tax collection help, use the Knox County Treasurer. If you need a copy of a deed, the Auditor Q&A points users to the Knox County Recorder.

💡
Simple route: Auditor for property records, values, exemptions, GIS/Tax Map, forms and licensing. Treasurer for tax bills and payment. Recorder for deeds and recorded documents. Board of Revision for formal value complaints.

Homeowners

Search your parcel, check value, review the tax tab, find exemption forms and save your parcel number before calling any county office.

Buyers and agents

Use property search, GIS/Tax Map, tax history, tax estimator and Recorder records together before making purchase, title or closing decisions.

Farm and land users

Use CAUV, Agricultural District, GIS/Tax Map and conveyance forms carefully because farm valuation and transfers can be deadline-sensitive.

03 — Records

What You Can Check in a Knox County Auditor Parcel Record

A Knox County property record helps homeowners, buyers, agents and researchers confirm owner information, parcel identity, property value, tax history and map context.

Record AreaWhy It MattersPractical Tip
Owner nameHelps verify the public owner of recordName changes require a new deed to be transferred and recorded.
Property addressConfirms site locationFor address questions, the Auditor Q&A points to GIS/Tax Maps at 740-393-6754.

📌
Record-reading tip: For serious due diligence, compare the Auditor property card, GIS/Tax Map, Treasurer tax status and Recorder deed record. One office rarely answers the full property question.
04 — GIS Maps

Knox County GIS/Tax Map, Parcel Boundaries and Real Estate Map Research

Knox County’s GIS/Tax Map tools help users research parcel location, nearby properties, mapping context, property boundaries and tax-map information.

The Knox County GIS Map page notes that maps are built from public records and are not intended to replace an accurate survey. Treat GIS as a research tool, not a legal boundary decision.

GIS/Tax Map

Useful for parcel location, map context and visual property research.

Tax Map Office

The county Tax Map Office is useful for real estate descriptions, land title research and maps or survey drawings.

Map caution

GIS map lines are helpful, but they are not a professional survey.

1
Open the Knox County Auditor GIS/Tax Map
Use this for map-based property research.

Open the Auditor GIS/Tax Map when you need parcel location, nearby properties or visual map context. Use it together with the parcel record, not instead of the parcel record.

Official GIS map: Knox County Auditor GIS Map

2
Use the Tax Map and GIS office for map questions
Best for descriptions, maps and survey drawing help.

If you need help with real estate descriptions, land title research, maps or survey drawings, use the Knox County Tax Map and GIS office resources.

Official county page: Knox County Tax Map and GIS

3
Do not use GIS as a legal survey
Important for fences, acreage and boundary disputes.

GIS is a public research tool. For acreage conflicts, easements, fences, boundary disputes or title-sensitive questions, use recorded documents, title review or a professional survey.

🗺️
Map tip: If an address is confusing, first locate the parcel in property search, then open the GIS/Tax Map using the parcel details. This reduces wrong-parcel mistakes.
05 — Taxes

Knox County Property Tax Due Dates, Treasurer Payments and Tax History

The Knox County Auditor provides property records, values, tax estimator access and tax-tab information. Tax bills are mailed and collected by the Knox County Treasurer.

The Auditor website currently shows 2026 real estate tax due dates as first half February 13, 2026 and second half July 10, 2026.

Tax payment tip: Before paying, confirm the parcel number and tax year. If you recently bought the property, taxes follow the property, so review closing documents and Treasurer records carefully.
06 — Value Review

Knox County Board of Revision, Property Valuation Complaints and Evidence Checklist

If you believe your Knox County appraised value is wrong, use the Knox County Board of Revision process. The Board of Revision page says DTE Form 1 must be filed with the County Auditor between January 1 and March 31.

Filing period

January 1 through March 31 for DTE Form 1 valuation complaints.

Exemption phone

740-393-6749 is listed for Exemption and BOR-related help.

Evidence matters

Prepare appraisal, sale, condition, repair or comparable-sale evidence before filing.

1
Review your parcel value first
Know exactly what you are challenging.

Open the parcel record and review value, property characteristics, sales information and tax tab data. Write down whether the issue is land value, building value, total value or incorrect property information.

2
Collect evidence before filing
A strong complaint needs more than a feeling.

Useful evidence may include a recent appraisal, purchase contract, closing statement, property condition photos, repair estimates, comparable sales or documents showing incorrect property characteristics.

3
Use the official Board of Revision page
Check current DTE Form 1 and rules.

The official Board of Revision page provides rules and DTE Form 1 for complaints against valuation. Always use the current official page, not an old PDF from search results.

Official BOR page: Knox County Board of Revision

⚖️
Value review warning: “My taxes are high” is not the same as “my value is wrong.” The Board of Revision reviews valuation evidence, while the Treasurer handles tax bills and collections.

Official homestead page: Knox County Homestead Exemption

3
Check CAUV rules before land transfer
Farm valuation can be sensitive to income, use and transfer rules.

The Auditor Q&A says CAUV may apply to farmland of ten acres or more used exclusively for agricultural use or smaller tracts meeting gross farm income requirements. Use the official CAUV page and forms before filing.

Official CAUV page: Knox County CAUV / Soil Rates

Form tip: Do not use old downloaded PDFs without checking the live Auditor Forms page first. Value complaints, homestead, CAUV and conveyance forms can change.

Official Recorder page
