Search Knox County Appraisal Records, Check Farm and Mineral Accounts, File Exemptions or Protests and Route Tax Payments Correctly
Use this guide to search a Knox County property by owner, address, property ID, abstract or account type, review market and taxable values, open the parcel map, apply for exemptions, document agricultural use, prepare an appraisal protest and locate tax or deed records.
Knox County Appraisal District appraises real property and business personal property in Knox County. Its search also includes mineral, automobile and mobile-home accounts. Tax collection varies by taxing unit, while the County and District Clerk records deeds and other official property documents.
Independent guide — official systems are required for the final search, filing, payment, protest or recorded-document request.Important Knox County Corrections and Warnings
| Issue | What the Current Official Sources Show | Best User Action |
|---|---|---|
| Official CAD website | The current official domain is knoxcad.com, with separate search, map, protest and taxpayer portals. | Begin at the official homepage rather than using a guessed appraisal-domain address. |
| Tax collection | The CAD site says it collects for its listed units except Seymour ISD and Crowell ISD. The state directory lists the County Tax Assessor-Collector as serving several consolidated units, including Seymour ISD. | Use the collecting office printed on the actual bill and call before sending payment when the collector is unclear. |
| Old exemption amounts | A local Knox CAD PDF still displays older $40,000 school homestead amounts. | Do not rely on that older table for a 2026 calculation. Check the current account and current Texas law. |
| Protest form link | The local forms page links a protest form titled for counties with populations greater than 120,000. | Use Knox CAD’s online protest or ask the office which current form applies before mailing a paper protest. |
| Office schedule | Monday-Thursday 9:00 a.m.-5:00 p.m.; Friday 9:00 a.m.-4:30 p.m.; closed noon-1:00 p.m. | Avoid arriving during lunch and call before a deadline-day visit. |

How to Search Knox County CAD Property Records
The official search provides Owner, Address, ID, ARB and Advanced Search tabs. It can filter real property, personal property, mineral, automobile and mobile-home accounts, as well as paid or unpaid status.
Go to Knox CAD Property Search. Confirm that the heading says Knox CAD before entering information.
The portal includes current and historical years. Choose the year shown on the appraisal notice, tax statement, protest filing or research request.
An ID search is normally more accurate than a name or address search and reduces the chance of opening another owner’s account.
For an owner, begin with only the first or last name. For an address, begin with the street number and main street name.
Select Real, Personal, Mineral, Auto or Mobile Home when the general search returns too many records.
Available fields include abstract, subdivision, geographic ID, neighborhood, owner ID, business name and account status.
Compare the owner, physical address, property ID, legal description, account type and selected year.
Check land, improvements, market value, appraised value, taxable value, exemptions, taxing units, payment status and available map links.
Print the record or save it as a PDF before filing an exemption, preparing a protest, requesting a correction or paying taxes.

How to Read a Knox County Appraisal Record
| Record Field | Plain-Language Meaning | What to Check |
|---|---|---|
| Property ID | The appraisal-system identifier assigned to the account. | Use it in appraisal, tax, exemption and protest communications. |
| Owner name | Ownership information currently displayed on the appraisal roll. | Compare it with the newest recorded deed or mineral instrument. |
| Property type | Real, personal, mineral, auto or mobile-home account. | Do not confuse the land account with a separate home, business or mineral account. |
| Market value | The district’s estimate of market value as of January 1. | Land, buildings, condition, use, production or asset information supporting the value. |
| Appraised value | The value after an applicable homestead limitation, circuit-breaker limitation or special appraisal. | Whether the expected limitation or productivity appraisal appears. |
| Taxable value | The amount remaining after exemptions for a taxing unit. | Values may differ among the county, school district, city and special districts. |
| Legal description | The descriptive land information associated with the account. | Verify it through recorded documents before legal use. |
| Acreage | The acreage used in the appraisal record. | Compare it with the deed, survey and any separately treated homesite. |
| Taxing units | The county, school, city and special districts connected to the account. | School district, city limits, hospital, drainage, groundwater and water-authority jurisdiction. |
| Paid or unpaid status | The status displayed for that account and tax year. | Confirm the collector and obtain an official receipt before treating a tax as paid. |
How to Use the Knox CAD Interactive Map
The official GIS map is useful for locating rural tracts, comparing neighboring accounts and understanding the general parcel layout. It does not establish a legal boundary.
Copy the property ID, owner name, abstract and legal description before opening GIS.
Use the Knox CAD Interactive Map.
Compare roads, towns, abstracts, neighboring parcels and physical features with the assessment record.
Consider road access, irrigation, water availability, terrain, improvements, utility lines, energy facilities and nearby land use.
Use the deed, recorded plat, field notes and a licensed survey for exact acreage or boundary decisions.
Knox County Homestead and Other Property-Tax Exemptions
Exemption applications are filed with Knox County Appraisal District. The forms page requires a driver’s-license copy or other information required by the Texas Property Tax Code and may require an additional affidavit in some situations.
| Exemption or Benefit | Who It May Help | What to Prepare |
|---|---|---|
| General residence homestead | An owner occupying the property as the principal residence. | Identification, ownership date, occupancy date and property information. |
| Age 65 or older | A qualifying homeowner who has reached age 65. | Age documentation and the residence-homestead application. |
| Disabled person | A qualifying owner meeting Texas disability requirements. | The evidence requested by the current official form. |
| Disabled veteran | Eligible veterans and certain surviving spouses. | VA disability documentation and the correct exemption application. |
| Surviving-spouse benefits | Certain surviving spouses meeting statutory conditions. | Death, marriage, occupancy and qualification documents. |
| Temporary disaster exemption | Property damaged by a qualifying declared disaster. | Damage photographs, repair information and event-specific documentation. |
| Solar or wind-powered device | Owners of qualifying renewable-energy devices. | System description, cost and installation information. |
| Religious, charitable or cemetery property | Organizations meeting ownership and use requirements. | Organizational documents and evidence of qualifying property use. |
Residence homestead checklist
- Knox CAD property ID
- Physical residence address
- Owner’s complete legal name
- Date the property was acquired
- Date occupancy as the principal residence began
- Texas driver’s license or identification information required by the form
- Prior residence and exemption information
- Manufactured-home ownership documents when applicable
- Age, disability, veteran or surviving-spouse evidence for additional relief
- Signed form and delivery confirmation
Knox County Agricultural and Wildlife Appraisal
Owning rural acreage does not automatically qualify the land for open-space agricultural appraisal. Qualification depends on land-use history, current agricultural use and Knox CAD’s local degree-of-intensity standards.
| Land Use | Useful Evidence | Common Problem |
|---|---|---|
| Cotton, wheat or other crops | Seed, fertilizer, irrigation, harvesting, sales, crop insurance and operator records. | Showing acreage but not active commercial agricultural use. |
| Cattle or grazing | Stocking records, leases, veterinary documents, fencing, water and livestock sales. | Keeping too few animals to meet the local intensity standard. |
| Hay production | Cutting, baling, equipment, production and sales records. | Providing photographs without production or expense evidence. |
| Wildlife management | Wildlife-management plan, annual report, habitat work and population records. | Assuming the natural presence of wildlife establishes qualification. |
| Use history | Prior applications, leases, receipts, dated photos and operator statements. | Documenting only the current year when historical use is required. |
| Mixed-use tract | Map separating the homesite, cropland, pasture, improvements and nonqualifying acreage. | Claiming the same treatment for every portion of the tract. |
Agricultural filing steps
Confirm acreage, owner, legal description and current appraisal treatment.
Compare the actual operation with the requirements for the claimed agricultural category.
Answer the ownership, acreage, prior-use and current-use questions completely.
Separate homesite acreage, crop fields, pasture, wildlife areas, roads and other uses.
Provide leases, receipts, sales, livestock, crop, water and management information that supports the claimed use.
Knox County Mineral, Oil and Gas Accounts
The official search includes a separate Mineral property type. Surface ownership and mineral ownership can differ, and one owner can have several separate mineral accounts.
Mineral-account review checklist
- Correct owner name and mailing address
- Property ID and tax year
- Lease, operator or well information
- Ownership or decimal interest where shown
- Recent mineral deed or assignment
- Probate or heirship documents
- Division orders and royalty statements
- Sold, transferred or duplicate interests
- Separate unpaid accounts under name variations
Business Personal Property and Renditions
Knox CAD appraises business personal property and publishes a current depreciation table. Taxable assets may include equipment, machinery, furniture, tools, computers, inventory and other income-producing property.
Use owner name, Doing Business As, address and Personal property type.
Include asset description, acquisition year, original cost, physical location and condition.
Identify third-party equipment and retain the lease, consignment or ownership agreement.
Keep invoices, disposal records, transfer documents and relocation information.
The Knox CAD forms page includes general personal-property renditions, dealer inventory forms, allocation forms and other specialized reports.
How to Protest a Knox County Appraised Value
A protest should identify the precise appraisal issue and provide evidence supporting the requested result. Complaining only about the final tax amount does not explain why the appraisal is incorrect.
Check the property ID, proposed market value, appraised value, exemptions, property description and filing deadline.
Review land, improvements, acreage, account type, mineral information, exemptions and tax year.
Possible issues include excessive market value, unequal appraisal, wrong property description, incorrect owner, denied exemption or denied agricultural appraisal.
Use comparable sales, dated photographs, repair estimates, surveys, closing records, leases, crop records, livestock records, asset lists or mineral documents.
Use Knox CAD Online Protest when the account is eligible. Save the confirmation.
Use the Knox CAD Protest Database for available protest or hearing information.
Review comparable properties, appraisal schedules, photographs and calculations before the hearing.
Begin with the requested value or correction, explain the strongest issue and present the clearest evidence first.
Confirm whether the hearing will be in person, by telephone, by videoconference or through a permitted written affidavit.
Read the decision and any deadline for arbitration, district-court review or another permitted remedy.
Useful Protest Evidence by Property Type
| Property Type | Useful Evidence | Common Mistake |
|---|---|---|
| Home in Benjamin, Knox City, Munday or Goree | Nearby sales, condition photographs, repair estimates and feature differences. | Using properties from a different town or substantially different condition. |
| Cropland | Irrigation, soil, production, access, leases and comparable land transactions. | Comparing irrigated and dryland acreage as equal. |
| Grazing or ranch land | Water, fencing, carrying capacity, terrain, access and similar ranch sales. | Using acreage alone without land-quality adjustments. |
| Mineral interest | Division orders, royalty statements, production, leases and recorded ownership documents. | Comparing only the prior year’s tax amount. |
| Business personal property | Asset ledger, original cost, acquisition date, condition, disposals and leased-property records. | Submitting evidence that conflicts with the rendition. |
| Mobile or manufactured home | Owner documents, serial information, age, condition, site and separate land-account details. | Confusing the home account with the land account. |
| Commercial property | Leases, vacancy, operating expenses, condition and market comparisons. | Providing gross revenue without occupancy and expense information. |
Important Knox County Property-Tax Dates
The exact date on the official notice or form controls. Weekends, legal holidays, notice mailing and statutory exceptions can affect a deadline.
| General Date | Common Task | What to Do |
|---|---|---|
| January 1 | Texas valuation date and date the property-tax lien generally attaches. | Keep evidence showing condition, use, inventory and ownership near January 1. |
| April 15 | General deadline for many business personal-property renditions. | File the rendition or an applicable timely extension request. |
| April 30 | Common deadline connected to many exemptions and agricultural-appraisal applications. | Confirm the exact filing and late-filing rules with Knox CAD. |
| May 15 or applicable later date | Typical deadline for many appraisal protests. | Use the exact deadline printed on the appraisal notice. |
| August-September | Taxing units propose and adopt rates. | Review Knox County Truth in Taxation notices and register for updates. |
| October or later | Current-year tax statements are commonly issued. | Search every account if a bill is not received. |
| January 31 | Common last day to pay current taxes before delinquency. | Verify the payment has posted and save the receipt. |
| February 1 | Unpaid current taxes generally become delinquent. | Request the current payoff including penalty and interest. |
How to Find and Pay Knox County Property Taxes
Knox County tax collection is not as simple as assuming one office handles every account. The CAD site and Texas Comptroller directory describe the collection arrangement differently for some school districts.
Safe payment process
Look for real, personal, mineral, auto and mobile-home accounts under the owner name and possible name variations.
A payment applied to one account does not pay another account belonging to the same owner.
Confirm the office, mailing address, online-payment route and account number shown on the current bill.
Contact County Tax Assessor-Collector Penny Eaton at 940-459-2411 or Knox CAD at 940-459-3891.
For a delinquent account, obtain a current amount that includes penalty, interest and any collection charge.
Do not assume a fee, bureau code or payment URL from another county applies to Knox County.
Keep the property ID, tax year, amount, collector, date and confirmation number.
Recheck each separate real, mineral, mobile-home and personal-property account before considering the owner’s taxes complete.
Knox County Truth in Taxation and Tax-Rate Notices
The Truth in Taxation site is for proposed tax rates, estimated taxes, public feedback and notifications. It is not automatically the final tax-payment portal.
Compare the owner, property ID and address before reviewing estimated taxes.
Compare proposed or adopted rates for the county, city, school and special districts connected to the property.
Scroll to the public-feedback and notification section, acknowledge ownership, enter contact information and select the notification option.
How to Find Knox County Deeds, Liens and Recorded Documents
The CAD record is an appraisal record, not legal proof of ownership. Knox County’s County and District Clerk handles recorded property documents.
Save the owner name, property ID, legal description, abstract and approximate transfer date.
Examples include warranty deed, deed of trust, release, lien, mineral deed, assignment, easement, plat or probate record.
Search both the person transferring an interest and the person receiving it when tracing ownership.
Provide the names, date range, document type and property description already known.
A matching owner name does not prove that a document belongs to the same tract.
Ask whether an ordinary copy or certified copy is needed for closing, probate, court or title work.

Local Knox County Property Considerations
| Area or Property Type | Important Checks | Why It Matters |
|---|---|---|
| Benjamin property | City limits, Benjamin ISD, lot, utilities, condition and nearby sales. | The county seat has a small market where property-specific differences can materially affect comparisons. |
| Knox City property | City jurisdiction, Knox City-O’Brien CISD, condition, lot and local services. | The correct city and school units affect taxable value and tax collection. |
| Munday or Goree property | Municipal limits, Munday CISD, utilities, improvements and market location. | A mailing address may not fully describe the appraisal and taxing jurisdiction. |
| Truscott, Vera or remote rural tract | Legal access, water, electricity, fencing, acreage, terrain and agricultural use. | Remote land may differ substantially from acreage near a highway or town. |
| Irrigated crop land | Well capacity, groundwater-district rules, irrigation equipment, energy cost and soil productivity. | Irrigated and dryland acreage are not automatically comparable. |
| Solar, wind or energy-related property | Lease, easement, tax abatement, improvements, access roads, transmission lines and change of use. | Energy development can create separate appraisal, contract and agricultural-use issues. |
| Mineral or royalty interest | Separate account, operator, lease, ownership interest, production and collecting office. | Surface and mineral estates may be separately owned, appraised and taxed. |
How to Correct a Knox CAD Record
