How to Appeal Property Taxes in Tennessee: Step-by-Step Guide for 2026
TL;DR
Tennessee homeowners can appeal their property tax assessment by filing with their County Board of Equalization. The deadline is during the County Board of Equalization open session (typically May-June in reappraisal years). The average effective property tax rate in Tennessee is 0.64%, and the average homeowner pays around $1,728 per year on a $270,000 home. If your assessment is too high, an appeal could save you hundreds or even thousands annually.
Property taxes in Tennessee are based on your property's assessed value, which is determined by your county assessor. If that value is too high, you pay more than you should. The appeal process exists specifically to correct these errors, and it costs nothing to file.
Here is exactly how to appeal your property taxes in Tennessee in 2026, including deadlines, procedures, and tips for building a winning case.
How Tennessee Property Tax Assessments Work
Tennessee assesses property at 25% of appraised value for residential. The valuation date is January 1 of the reappraisal year (counties reappraise every 4-6 years), meaning your property's value is based on market conditions as of that date. Notices mailed during reappraisal years, typically April-May.
The fiscal year runs July 1 - June 30. Tax bills are calculated by multiplying your assessed value by the local mill rate (or tax rate), which is set by your county, city, school district, and other taxing authorities.
Key Deadlines for 2026
| Event | Deadline/Date |
|---|---|
| Valuation date | January 1 of the reappraisal year (counties reappraise every 4-6 years) |
| Assessment notices mailed | Notices mailed during reappraisal years, typically April-May |
| Appeal deadline | During the county board of equalization open session (typically may-june in reappraisal years) |
| Further appeal | State Board of Equalization (Assessment Appeals Commission), then Chancery Court |
Step-by-Step: How to Appeal Your Tennessee Property Tax Assessment
Step 1: Review Your Assessment Notice
When you receive your notice, check every detail. Verify the square footage, lot size, number of bedrooms and bathrooms, year built, and any special features. Errors in property characteristics are the easiest wins in an appeal because the facts speak for themselves.
Step 2: Research Comparable Sales
Look for 3-5 homes similar to yours that sold near the valuation date (January 1 of the reappraisal year (counties reappraise every 4-6 years)) for less than your assessed value. Good comps share your neighborhood, approximate size, age, and condition. The closer the match, the stronger your case.
Step 3: File Your Appeal
File your appeal with the County Board of Equalization during the County Board of Equalization open session (typically May-June in reappraisal years). In most Tennessee counties, you can file by mail, in person, or online (check your county assessor's website). Include a written explanation of why you believe your assessment is too high, along with your supporting evidence.
Step 4: Prepare Your Evidence
Strong evidence includes:
- Comparable sales data: Recent sales of similar properties at lower values
- Property condition issues: Foundation problems, outdated systems, needed repairs, environmental issues
- Photos: Document any defects or conditions that reduce your property's value
- Equity arguments: Show that comparable properties in your area are assessed lower than yours
- Independent appraisal: A recent professional appraisal showing a lower value
Step 5: Attend Your Hearing
Present your case clearly and concisely. Stick to facts and data. Bring copies of all evidence for the board members. Be respectful but firm. If you have a professional appraisal or contractor estimates for repairs, those carry significant weight.
Step 6: Further Appeals If Needed
If you disagree with the County Board of Equalization's decision, you can escalate to State Board of Equalization (Assessment Appeals Commission), then Chancery Court. Each level of appeal has its own deadlines, so act quickly if you want to continue.
County-Specific Appeal Information
Davidson County (Nashville)
Nashville's boom has driven massive value increases. The Metro Nashville Assessor of Property handles Davidson County. File your appeal with the County Board of Equalization during their open session, typically in May-June of the reappraisal year.
Shelby County (Memphis)
The largest county by population. The Shelby County Assessor conducts reappraisals on the state-mandated cycle. Memphis has seen uneven appreciation, making individual property comparisons important.
Knox County (Knoxville)
East Tennessee's hub. Knox County's last reappraisal brought significant increases in many neighborhoods. Check that your neighborhood's growth rate matches the assessor's numbers.
Hamilton County (Chattanooga)
Chattanooga's revitalization has pushed values up, especially downtown and on the North Shore. Verify that the assessor is using appropriate comps for your specific area.
Williamson County (Franklin)
One of the wealthiest counties in Tennessee. High values mean even small percentage errors translate to meaningful tax savings.
Tennessee Property Tax Exemptions
Before or alongside your appeal, make sure you are claiming every exemption you qualify for. Exemptions reduce your taxable value directly, saving you money every year.
| Exemption | Details |
|---|---|
| Tax Relief for Elderly | Reimbursement of property taxes for homeowners 65+ with income under $31,600. Covers taxes on the first $30,100 of full market value. |
| Tax Relief for Disabled | Same program as elderly relief for totally and permanently disabled homeowners with income under $31,600 |
| Disabled Veteran Exemption | First $175,000 of property value exempt for veterans with 100% permanent, service-connected disability |
| Tax Freeze for Seniors | Homeowners 65+ with income under $47,030 can freeze their property taxes at the current amount |
Tips for a Successful Tennessee Property Tax Appeal
Focus on Comparable Sales
The single most persuasive piece of evidence is comparable sales data showing similar homes sold for less than your assessed value. Boards and assessors deal in market data. Give them solid numbers.
Check for Property Record Errors
Assessors work from property records that may contain mistakes. Wrong square footage, extra bathrooms, incorrect lot size, or a missing condition note can inflate your value. Verify everything against your actual property.
Document Property Condition Issues
If your home needs a new roof, has foundation issues, or has other problems that a buyer would negotiate on, document them with photos and repair estimates. The assessor may not know about these issues.
File Every Year
Even if you won last year, your assessment can go up again this year. Make annual appeals part of your routine. There is no penalty for appealing, and your assessment cannot go up as a result of your appeal in most jurisdictions.

The statewide average effective rate is 0.64%, but rates vary significantly by county and taxing district. Your actual rate depends on where you live and which school district, city, and special districts tax your property.
On a home valued at $270,000, the average Tennessee homeowner pays about $1,728 per year. Reducing your assessed value by just 10% could save you $172 or more annually.
Frequently Asked Questions
What is the deadline to appeal property taxes in Tennessee?
The deadline is during the County Board of Equalization open session (typically May-June in reappraisal years). Missing this deadline generally means waiting until next year, so mark your calendar.
How much does it cost to appeal property taxes in Tennessee?
Filing an appeal is free. You may incur costs only if you hire a professional appraiser, attorney, or if you escalate to court. The initial appeal to the County Board of Equalization costs nothing.
Can my property taxes increase if I appeal?
In most cases, your assessed value will not increase as a result of filing an appeal. The worst outcome is typically that your value stays the same. However, if the review board discovers a significant error that understated your value, a correction is possible in rare cases. This is uncommon.
Do I need a lawyer to appeal?
No. The appeal process is designed for property owners to handle themselves. For high-value or complex properties, professional help can be worth it, but most residential appeals are straightforward.

The initial appeal typically takes 1-3 months from filing to decision. Further appeals to State Board of Equalization (Assessment Appeals Commission), then Chancery Court can take additional months.
What evidence works best in a property tax appeal?
Comparable sales of similar homes that sold for less than your assessed value are the strongest evidence. Property condition documentation, independent appraisals, and equity comparisons with similarly assessed nearby properties also carry weight.
