Knox County Property Search, 2026 Reappraisal, KGIS & Tax Lookup
For a Knox County property assessor search, start with Property Assessor Phil Ballard’s official property database for appraisal and assessment details, then use KGIS when you need parcel mapping, owner/address searching or geographic context. County property taxes are billed and collected by the Knox County Trustee—not by the Property Assessor.
2026 is especially important because Knox County completed a full countywide reappraisal and moved to a new two-year reappraisal schedule. That means current values are intended to represent the 2026 market cycle, with the next countywide reappraisal expected in 2028. This guide also shows how to separate county tax from City of Knoxville tax, how to check a late appeal deadline, and where to verify deeds and Greenbelt records.

What Knox County Property Owners Need to Know Right Now
2026 values are reappraisal values
Knox County reappraised all real property for 2026. This is not merely an annual ownership update.
Residential informal appeals ended
The Property Assessor’s 2026 informal residential review period has concluded.
State appeal may still be possible
The general August 1 state filing date passed, but the deadline can instead be 45 days after the County Board action notice if that date is later.
Greenbelt deadline passed
The Assessor calendar lists March 15 as the annual Greenbelt application deadline.
2026 Tax Freeze limit
Tennessee lists Knox County’s 2026 Property Tax Freeze income ceiling at $63,470.
County taxes start in October
Knox County’s assessment calendar identifies October 1 as the date current-year taxes become due and payable.
Important 2026 rate warning: the Property Assessor’s tax calculator still states that it reflects the 2025 rate structure. Do not use that calculator as proof of the final 2026 county rate without checking the Trustee’s current tax account or adopted county tax information.

How to Search Knox County Property Assessor Records
Open the official property search.
Use Knox County Property Search.
Accept the county data disclaimer.
The records site requires users to accept its property-record disclaimer before searching.
Search the parcel.
Use owner, address, parcel or the available real-property search fields.
Confirm the correct result.
Compare address, owner, parcel identifier and subdivision information.
Open the Values section.
The Assessor’s current instructions identify Total Appraised under the Values tab as the value used to begin tax calculations.
Check the classification.
Residential, farm, commercial, industrial and other classifications use different statutory assessment percentages.
Save the parcel ID.
Use the same identifier when moving to KGIS, the Trustee, City tax search or deed research.
If the property database displays a maintenance message: use KGIS as a practical fallback for owner/address/parcel identification, then return to the Assessor system for the detailed appraisal record.
How to Use KGIS for Knox County Parcel Search
KGIS is one of the most useful Knox County property tools because its public search supports Address, Parcel and Owner queries.
Address Search
Find the mapped parcel when you know the street location.
Parcel Search
Use the property identifier for a more exact match.
Owner Search
Search the GIS index by an owner name when the address is unknown.
General parcel lines
Compare property shape, neighboring parcels and roads.
Other map layers
KGIS supports multiple public planning, school, neighborhood and geographic tools.
Historical maps
KGIS also maintains Knox County historical map resources extending back into the 1800s.
Property-line caution: the Property Assessor specifically says KGIS should be used for general property-line information. If exact property lines matter for a fence, construction project or dispute, a survey is required.
Open KGIS Search
Choose Address, Parcel or Owner and then open the mapped result.
Knox County Property Record Decoder
| Field | What it means | What to do with it |
|---|---|---|
| Parcel / Property ID | Local identifier connecting the parcel with mapping and tax systems. | Save it before switching systems. |
| Owner | Owner reflected in assessment records. | Verify the actual deed when legal ownership matters. |
| Appraised Value | Assessor’s estimate of market value. | Apply the statutory classification percentage to calculate assessed value. |
| Assessed Value | Taxable assessment base before tax-rate calculation and certain relief adjustments. | Apply the applicable tax rate per $100 of assessed value. |
| Classification | Residential, farm, commercial, industrial or another statutory class. | Classification determines the assessment ratio. |
| Land Value | Appraised contribution assigned to the land. | Compare with improvement/building value. |
| Improvement Value | Value attributed to buildings and taxable improvements. | Check recent permits, additions and demolition. |
| Greenbelt | Potential qualifying use-value classification for agricultural, forest or open-space land. | Confirm active status with the Assessor rather than assuming acreage qualifies. |
| Sales History | Transfers used for property and appraisal research. | Verify the recorded instrument with Register of Deeds. |
Knox County’s 2026 Reappraisal and New Two-Year Cycle
The Property Assessor completed a countywide reappraisal for 2026. The office evaluated real-property characteristics, permits, demolitions, new construction, comparable sales and local market trends to update values.
Every real-property parcel
The 2026 project was a countywide reappraisal rather than a small neighborhood update.
Market date
Tennessee reappraisal values are intended to reflect market value as of January 1 of the reappraisal year.
Permit review
New construction, structural changes and demolition are among the property changes tracked.
Two-year cycle
Knox County changed from a four-year reappraisal schedule to a two-year schedule beginning in 2026.
Next expected cycle
The Property Assessor identifies 2028 as the next reappraisal year.
Reappraisal is not a tax rate
The Property Assessor establishes property value; county and city governing bodies establish tax rates.
Why the shorter cycle matters: more frequent market updates are intended to reduce the size of valuation jumps that can build up during longer four-year cycles.
How Knox County Converts Appraised Value to Assessed Value
25%
Residential
Residential real property is generally assessed at 25% of appraised value.
25%
Farm
Farm real property also generally uses a 25% assessment ratio.
40%
Commercial / Industrial
Commercial and industrial real property generally uses 40%.
30%
Business Personal
Tangible commercial/industrial personal property generally uses a 30% assessment percentage.
Residential example: a home appraised at $400,000 has a $100,000 assessed value because $400,000 × 25% = $100,000. Property-tax rates are then applied per $100 of assessed value.

+45 DAYS
Later Notice Rule
A taxpayer can use 45 days after the County Board action notice when that deadline falls later.
As of August 12, 2026: the general August 1 filing date has passed. If you recently received a County Board of Equalization decision, count 45 days from the date the action notice was sent before assuming the State Board deadline is gone.
Strong evidence for a value dispute
- Recent comparable sales
- Recent purchase of the subject property
- Independent appraisal under one year old
- Incorrect square footage
- Incorrect land size
- Condition photographs
- Repair estimates
- Demolition documentation
- Permit information
- Correct property classification
Appeal the value—not the tax amount. Tennessee assessment appeals concern valuation, classification and related assessment issues. A complaint that the tax bill is simply “too high” is not itself a valuation appeal.

Does a Knoxville Address Owe City Property Tax Too?
A property located inside the incorporated City of Knoxville can owe both Knox County property tax and a separate City of Knoxville property tax.
2026–27 city rate
The City of Knoxville adopted budget information keeps the city property-tax rate at $2.1556 per $100 of assessed value.
City bill date
Knoxville city real-estate taxes are billed October 1.

Knox County 2026 Senior Property Tax Freeze
Knox County participates in Tennessee’s local-option Property Tax Freeze. It can lock the qualifying homeowner’s property tax at a base amount even when appraised value or tax rates later increase.
Age
Applicant must be 65 or older by the end of the year for which the application is filed.
2026 Knox income ceiling
$63,470.
Principal residence
The benefit applies only to the qualifying principal residence.
Annual application
Tax Freeze is not a one-time permanent filing; qualifying owners must reapply annually.
Improvement can change base
New improvements can increase the frozen tax base.
Can combine with Relief
Tax Freeze can be received in addition to Property Tax Relief when the owner separately qualifies for both.
2026 filing period: the Knox County Trustee’s 2026 eligibility page listed April 5, 2026 as the application deadline. That date has passed for the current application year.
Greenbelt property: Tennessee says the freeze applies only to the residential portion—the dwelling, residential outbuildings and homesite—not the full qualifying Greenbelt tract.
Verify 2026 Tax Freeze Rules
Check Knox County’s $63,470 limit and statewide qualification rules.
Knox County Property Tax Relief
The Knox County Trustee administers Tennessee Property Tax Relief applications for qualifying elderly, disabled and disabled-veteran homeowners and eligible surviving spouses.
Elderly homeowner
Age, income, ownership and principal-residence requirements apply.
Disabled homeowner
Disability and income requirements apply under the state program.
Disabled veteran
Separate service-connected disability qualification rules apply without the ordinary elderly-income test.
Relief is not an exemption. Tennessee describes Property Tax Relief as state payment or reimbursement of qualifying property tax. Owners still receive a tax bill and remain responsible for any balance not covered by relief.
Knox County Tax Relief
Use the Trustee for applications, document requirements and program questions.
Knox County Greenbelt Property Assessment
Tennessee’s Greenbelt program values qualifying agricultural, forest and open-space land based on qualifying present use rather than unrestricted highest-and-best-use market value.
Agricultural land
Eligibility depends on statutory acreage/use requirements and actual agricultural qualification.
Forest land
Qualifying forest acreage can receive use-value treatment under Tennessee law.
Open space
Separate open-space criteria apply; acreage alone does not guarantee eligibility.
2026 normal deadline passed: Knox County’s published annual calendar lists March 15 as the Greenbelt application deadline.
Sale or change of use: Greenbelt property can generate rollback-tax consequences when qualifying use ends. Do not evaluate a farm or development purchase from the current tax bill alone.
Open Knox County Greenbelt Guidance
Review current agricultural, forest and open-space classification information.
Knox County 2026 Business Personal Property
Businesses operating for profit generally must report taxable tangible personal property such as machinery, computers, furniture and equipment to the Property Assessor.
Schedule mailed by Feb. 1
The Assessor mails tangible personal-property schedules to businesses.
2026 due date was March 1
The timely online filing window is now closed.

Forced assessment risk
Businesses that fail to return a schedule can receive a forced assessment.
30% assessment ratio
Tangible commercial/industrial personal property is assessed at 30% of depreciated/forced value.

Knox County Delinquent Taxes & Tax Sale
March 1 delinquency
Unpaid preceding-year property tax becomes delinquent on March 1.
Balance increases
Penalty, interest and collection expenses can make the current payoff higher than the original tax bill.
Tax sale is a last resort
The Trustee describes delinquent tax sale as a court-driven collection measure for severely delinquent parcels.
Do not pay an old amount from memory. Search the live Trustee account or contact 865-215-2305 for the current balance when a parcel is delinquent.
Knox County Property Search Problems & Fixes

| Want to appeal in August | Check the date of any County Board action notice for the 45-day State Board rule. | CBOE / SBOE |
| Knoxville address has no city tax | A Knoxville mailing address does not prove the parcel is inside city limits. | KGIS |

Knox County Property Assessor FAQs
1. How do I search Knox County property assessor records?
Use the official Knox County Property Assessor real-property search for appraisal and assessment details. KGIS is an excellent companion search because it supports owner, address and parcel searches plus general parcel mapping.
2. Who is the Knox County Property Assessor in 2026?
Phil Ballard is the Knox County Property Assessor. The main office is in the Knoxville City-County Building at 400 Main Street, Knoxville, Tennessee 37902, and the general phone number is 865-215-2360.
3. Was Knox County property reappraised in 2026?
Yes. Knox County completed a countywide real-property reappraisal for 2026. The county has also moved to a two-year reappraisal cycle, with the next regular countywide reappraisal expected in 2028.
4. What percentage of appraised value is assessed for a Knox County home?
Residential real property is generally assessed at 25% of appraised value. A $400,000 residential appraisal therefore produces a $100,000 assessed value before the applicable county and, when relevant, City of Knoxville tax rates are applied.
5. Can I search Knox County property by owner name?
Yes. KGIS provides a public Owner search in addition to Address and Parcel searching. The Property Assessor database also provides real-property search tools for locating parcel records.
6. Does every Knoxville mailing address owe City of Knoxville property tax?
No. A Knoxville postal address does not automatically mean the parcel is inside Knoxville’s incorporated city limits. Use KGIS and the City property-tax search to verify municipal jurisdiction. Property actually inside Knoxville can owe both city and county property tax.
7. Can I still appeal my Knox County 2026 value in August?
The ordinary 2026 local appeal season and the general August 1 State Board deadline have passed. However, Tennessee allows a State Board appeal within 45 days after the County Board action notice when that deadline is later, so owners with a recent County Board decision should check their notice date immediately.
8. What is the Knox County Tax Freeze income limit for 2026?
The Tennessee Comptroller lists Knox County’s 2026 Property Tax Freeze income limit at $63,470. The applicant must also satisfy age, ownership, principal-residence and annual application requirements.

The Knox County Trustee currently lists a 2.5% third-party processing fee for credit-card payments and a $1 processing fee for e-check payments.
