Knox County Property Tax Guide: Pay, Search, Due Dates & Exemptions
Knox County property tax is handled through separate offices. The Knox County Trustee collects county property taxes, while the Knox County Property Assessor values property, maintains assessment records and helps route value appeals.
Use this guide to search your bill, pay safely, understand due dates, calculate the amount, avoid delinquency, check tax relief or senior freeze options, handle city tax questions, and appeal a value or classification problem.
Quick Answer: Start With the Right Office
For a Knox County property tax bill, balance, receipt, payment method or delinquent-tax question, start with the Knox County Trustee. For property value, classification, property record errors, business personal property, Greenbelt, exemptions or appeals, start with the Knox County Property Assessor.
If the property is inside Knoxville city limits, you may also have a separate City of Knoxville property tax bill. Paying the county bill does not automatically mean the city bill is paid.

How to Search Knox County Property Tax Records
The official Knox County property tax lookup lets users find county tax information and make county tax payments. Search carefully before paying because a similar address, old owner name or wrong parcel can lead to the wrong account.
Use parcel ID, owner name, property address, bill information or prior-year records if available. Always confirm the property address, owner, tax year, parcel and balance before making a payment.

Knox County Property Tax Due Dates
Knox County property taxes become due and payable on October 1. Taxes become delinquent on March 1 of the following year. This means the practical no-delinquency payment window normally runs from October through the last day of February.
Deadlines can be affected by weekends, holidays, posted county notices, reassessment activity, bank processing, mail timing or special account situations. Always check the current tax bill and Trustee account.
| Date / Period | What It Means | What to Do |
|---|---|---|
| January 1 | Assessment date used for many Tennessee property records and ownership/value questions. | Keep purchase, sale, condition and property-change records tied to this date. |
| February 1 | Business tangible personal property schedules are mailed by the assessor around this date. | Businesses should watch for the schedule and request one if not received. |
| March 1 | Prior year taxes become delinquent; business personal property schedules are due; some correction routes also use this date. | Pay before this date and file required business schedules on time. |

Deadline warning: Do not wait until February 28 or 29 to solve portal, escrow, address or bank problems. Taxes become delinquent March 1.
How Knox County Property Tax Amount Is Calculated
The Property Assessor appraises and assesses the property. The Trustee collects the tax bill. The final tax amount depends on appraised value, classification percentage, assessed value, tax rate and any city or special district charges.
In Tennessee, assessment percentages differ by property class. Knox County’s assessor guidance lists residential and farm property at 25%, commercial and industrial at 40%, public utility at 55%, and business personal property at 30%.
Estimated tax = appraised value × assessment percentage × tax rate. For a residence appraised at $100,000, assessed value is $25,000 before the tax rate is applied.
| Property Class | Assessment Percentage | What It Means |
|---|---|---|
| Residential | 25% | Most owner-occupied and rental houses fall into residential classification. |
| Farm | 25% | Farm property can have separate land-use and Greenbelt questions. |
| Commercial and industrial | 40% | Used for many business real estate accounts. |
| Business personal property | 30% | Applies to taxable furniture, fixtures, machinery and equipment used in business. |
| Public utility | 55% | Often handled through state-assessed property rules. |
- Search the Property Assessor record.
- Find appraised value and classification.
- Apply the proper assessment percentage.
- Use the Trustee bill for the final tax rate and amount due.
- For city properties, check whether a city bill also applies.
Trustee vs Property Assessor: Do Not Contact the Wrong Office
Many Knox County tax problems are delayed because users call the payment office for a value problem or call the assessor for a receipt problem.
| Issue | Trustee? | Assessor? | Reason |
|---|---|---|---|
| Need to pay bill | Yes | No | The Trustee collects taxes. |
| Need receipt | Yes | No | Payment records are collection records. |
| Value too high | No | Yes | Assessment value is an assessor and appeal issue. |
| Wrong square footage | No | Yes | Property record data belongs with the assessor. |
| Tax relief application | Yes | Sometimes | The Trustee receives relief/freeze applications; assessor records may support eligibility. |
| Business personal property schedule | No | Yes | Business tangible personal property is assessed through the assessor. |
Knox County Tax Relief and Senior Tax Freeze
Knox County participates in Tennessee property tax relief and senior tax freeze programs. These programs are not the same as a normal homeowner exemption. Tax relief may reimburse or pay part of the tax for qualifying homeowners, while tax freeze can lock the tax amount for qualifying seniors.
The Trustee’s latest published 2025 program materials list elderly/disabled tax relief, disabled veteran relief, surviving spouse options and senior tax freeze rules. Amounts, income limits and deadlines can change, so use the Trustee page for the current application cycle.
| Program | Who It May Help | Latest Published Knox Detail | What to Prepare |
|---|---|---|---|
| Elderly tax relief | Low-income homeowners age 65 or older by the program year deadline. | 2025 page lists income limit of $37,530 and relief up to $91. | ID, income proof, property ownership and primary residence documents. |
| Disabled homeowner relief | Homeowners approved for disability by the program date. | Uses same income limit as elderly/disabled program in latest posted materials. | Disability approval, income proof, ID and ownership documents. |
| Disabled veteran relief | Veterans with qualifying service-connected disability or qualifying surviving spouse. | 2025 page lists disabled veteran or widow(er) relief up to $487 and no income limit. | VA rating, discharge/eligibility documents, ID and application forms. |
| Senior tax freeze | Homeowners age 65 or older who meet the income limit and primary-residence rules. | 2025 page lists income limit of $61,920 and freeze for home plus up to five acres. | ID, income proof for owners, trust/life estate/mobile home documents if applicable. |
- Open the Trustee Tax Relief and Tax Freeze page.
- Check the current program year, income limit and deadline.
- Download the correct application.
- Sign every required form.
- Attach ID, income, ownership, disability, veteran, trust or mobile home documents as needed.
- Submit by mail or in person at a Trustee location.
Relief warning: These programs usually require annual requalification, proof of eligibility and signed applications. Do not assume approval continues automatically.
Knox County Property Tax Exemptions and Greenbelt
Tennessee does not use a broad automatic homeowner exemption like some states. In Knox County, “exemptions” usually refer to qualifying religious, charitable, scientific, nonprofit educational, governmental or other exempt-use property, plus special programs such as Greenbelt for qualifying land.
Organizations seeking exemption must apply for every parcel on which exemption is sought. If tangible personal property is included, the applicant should identify the property and any taxing identification information from the county assessor.
| Program / Route | Who It Helps | Key Point | Official Route |
|---|---|---|---|
| Religious / charitable / scientific / nonprofit educational exemption | Qualifying organizations and qualifying property use. | Ownership, governing documents and actual property use matter. | Knox Exemptions |
| Construction exemption | Qualifying exempt organizations with property under construction. | Application timing can matter before or within 30 days of construction beginning. | Exemption Details |
| Greenbelt | Agricultural, forest or open-space land meeting Tennessee law. | Land may be valued by present use instead of highest and best use. | Greenbelt Guide |
| Tax relief / freeze | Eligible elderly, disabled, disabled veteran and senior homeowners. | This is relief or freeze, not a normal exemption from assessment. | Tax Relief / Freeze |
- Confirm the land may qualify as agricultural, forest or open space.
- Review acreage, use and ownership rules.
- File by the Knox County Greenbelt deadline.
- Understand rollback tax risk before changing use or selling.
- Keep production, forest, open-space or planning documents.
How to Appeal a Knox County Property Assessment
An appeal is about value, classification or property facts. “My tax bill is too high” is not the strongest appeal argument by itself. The appeal should explain why the appraised value, classification or assessment record is wrong.
Knox County’s appeal route can include informal discussion with the Assessor, County Board of Equalization in June, State Board of Equalization, and later court review if statutory deadlines and procedures are followed.
| Appeal Stage | What Happens | What to Prepare |
|---|---|---|
| Informal review | You discuss value or property record concerns with the Assessor’s Office. | Comparable sales, appraisal, photos, repairs and property detail corrections. |
| County Board of Equalization | The county board hears assessment complaints during June. | Short evidence packet and specific requested value or classification. |
| State Board of Equalization | A taxpayer may appeal beyond the county board to the state route. | County decision notice, filing proof and organized evidence. |
| Administrative Law Judge | State-level hearing may be held; notice is usually sent before the scheduled hearing. | Witnesses, sales, appraisal, property facts and legal appeal documents. |
| Chancery Court | Judicial review may be available after final state action. | Qualified legal help and strict deadline tracking. |
- Open the Knox County Property Assessor record.
- Confirm land size, building size, year built, condition, classification and use.
- Gather comparable sales and market evidence near the assessment date.
- Prepare photos, repair estimates, appraisals or closing documents.
- File informal or formal appeal before the posted deadline.
- Pay the tax bill on time unless official instructions say otherwise.
Appeal warning: The Trustee cannot lower your property value. Appeal value or classification through the Assessor and Board of Equalization route.
Evidence Checklist for a Knox County Assessment Appeal
Good evidence is specific, local and tied to the property. The best evidence explains why the county’s value or classification should change.
Use similar properties in the same area with similar size, age, condition and sale timing.
A recent arm’s-length sale or independent appraisal can support your requested value.
Show damage, unfinished work, foundation issues, roof problems, water damage or deferred maintenance.
Use surveys, permits, plans or measurements to correct square footage, land size or features.
Use asset schedules, depreciation records, invoices and disposal records for tangible personal property.
Use acreage, production, forest or open-space documents if land-use valuation is the issue.
Business Tangible Personal Property in Knox County
In Tennessee, tangible personal property tax generally applies to businesses, not ordinary household personal items. Knox County’s Assessor handles business personal property such as furniture, fixtures, machinery and equipment used for business or professional activity.
Schedules are mailed by February 1 and should be returned by March 1. Businesses that do not file may receive a forced assessment. If a timely filed schedule later needs correction, the business may have until September 1 of the following year to amend it.
| Business Property Topic | Official Detail | What to Do |
|---|---|---|
| Who files | Businesses and professions operating for profit may need to report tangible personal property. | Request help if your business receives no schedule. |
| What to report | Total acquisition cost new, including freight, installation, setup and sales tax. | Keep invoices and asset lists by year acquired. |
| Schedule due date | Schedules are due by March 1. | File early and keep confirmation. |
| Forced assessment | Businesses that do not return a schedule will be assigned a forced assessment. | Avoid forced assessment by filing on time. |
| Amended schedule | Timely filers may amend by September 1 of the following year if an error is found. | Do not wait if assets were sold, duplicated or reported incorrectly. |
City of Knoxville Property Tax vs Knox County Property Tax
Property inside Knoxville city limits may have both county and city tax obligations. The City of Knoxville tax search is separate and states that its website provides tax information for the City of Knoxville only.
For city tax questions, use the City of Knoxville property tax office. For county tax information, use the Knox County Trustee.
| Bill Type | Office | Search / Payment Route | Contact |
|---|---|---|---|
| Knox County property tax | Knox County Trustee | County tax lookup | 865-215-2305 |

| City tangible personal property tax | City of Knoxville | City tangible personal property search | City Tax Office |
City-resident warning: Paying one bill does not automatically pay the other. If your property is inside city limits, check both county and city records.
Bank Draft, Delinquent Plans and Tax Sale Risk
The Knox County Trustee offers a prepayment bank draft plan for owners who want to spread future taxes across monthly drafts. Prior taxes must be paid before signing up for the prepayment plan.
The Trustee also describes a delinquent tax bank draft plan that can help homeowners bring delinquent taxes current through monthly bank drafts over a plan period. Long-term delinquency can create serious collection and tax sale risk.
| Option | Who It Helps | Important Detail |
|---|---|---|
| Prepayment bank draft | Owners who want to pay toward the next tax bill monthly. | All prior property taxes must be paid before signup. |
| Automatic renewal | Owners who want ongoing monthly drafts. | Trustee page says the bank draft renews automatically each January unless terminated. |
| Delinquent tax bank draft | Homeowners trying to bring delinquent taxes current. | Participants must contact the office to determine draft amount. |
| Tax sale review | Owners or buyers dealing with seriously delinquent parcels. | Tax sale properties involve risks, restrictions and court procedures. |
- Confirm all prior taxes are paid if using prepayment draft.
- Open the Trustee Bank Draft Program page.
- Review the monthly draft calculation rules.
- Contact the Trustee if taxes are already delinquent.
- Keep bank account and confirmation records.
New Knox County Homeowner Checklist
New owners should not assume the prior owner’s tax setup, mailing address or mortgage escrow details are correct. Search both assessment and tax records soon after closing.
Corrections, Mailing Address and Property Record Errors
If the issue is a simple clerical error, wrong mailing address, duplicate assessment, property description mistake or classification error, contact the Assessor quickly. Knox County’s calendar notes correction rules and deadlines for errors or omissions by the assessor.
Correctable errors generally involve obvious clerical mistakes and do not include every disagreement about value. If the issue requires judgment about market value, use the appeal process instead.
Update mailing address so assessment notices, appeal letters and tax bills are not missed.
Check square footage, land size, buildings, outbuildings, use and classification.
Compare parcel numbers and tax years if the same property appears twice.
Use appeal evidence when the issue is market value, not a simple clerical record problem.
