How Assessment Works in Tennessee
Tennessee assesses residential property at 25% of appraised (market) value. Commercial and industrial property is assessed at 40%. Farm property is assessed at 25% of farm-use value. Your tax bill is based on the assessed value, not the full appraised value.
Risk of Increase
In Tennessee, filing a appeal can result in your assessed value being increased. This is uncommon when you have strong evidence of over-assessment, but you should be aware of this possibility. ProtestMax only recommends filing when our analysis shows a clear case for reduction.

FAQ
Tennessee Property Tax Appeal Questions
How does the 25% ratio work in Tennessee?
If your home's appraised value is $400,000, the assessed value is $100,000 (25%). Your tax bill is based on $100,000 multiplied by your local tax rate. If the county over-appraises your home, you pay taxes on a higher assessed amount.
Can my Tennessee assessment increase on appeal?
Yes. The Board of Equalization can increase your assessment. However, this is uncommon when you present strong evidence of over-assessment.
How often does Tennessee reassess?
Tennessee counties conduct reappraisals on a 4, 5, or 6-year cycle, depending on the county. Between reappraisals, values generally remain the same unless there are physical changes.
What is the effective property tax rate in Tennessee?
Tennessee property tax rates vary by county, municipality, and school district, but the effective rate (annual tax paid divided by market value) typically ranges from about 0.5% to 2.5%. Because Tennessee assesses property at 25% (residential) of market value, your actual tax bill depends on both the assessed value and the local millage or mill levy applied on top of it. If your assessed value is higher than comparable sales support, filing a appeal is one of the only ways to reduce your effective rate without waiting for a reassessment.
How long does a property tax appeal take in Tennessee?
Most Tennessee appeals take between 6 weeks and 6 months from filing to final decision. After you file County Board of Equalization appeal, the assessor or review board schedules a hearing — typically within 30 to 90 days — and issues a written decision shortly after. Cases that settle informally resolve faster, while cases that advance to a formal hearing or court appeal can take several additional months. ProtestMax prepares your full evidence packet in minutes so you can file immediately and start the clock.
Can I appeal my property taxes every year in Tennessee?
Yes. In Tennessee, homeowners generally have the right to appeal their property tax assessment every year, as long as you file by the June 15, 2026 or within 45 days of notice deadline. Even if you won a reduction last year, your assessor can revalue your property the following year, and you retain the right to challenge the new value. Annual appeals are especially important during years when market values are flat or falling but assessments keep rising.
What evidence is most persuasive in Tennessee hearings?
The strongest evidence in a Tennessee appeal hearing is recent comparable sales — homes similar to yours in size, age, condition, and location that sold for less than your assessed value within the last 6 to 12 months. Equity comparisons (similar homes assessed for less than yours) are also highly persuasive. Photos of deferred maintenance, structural issues, or negative location factors (busy roads, flood zones, power lines) strengthen your case further. ProtestMax assembles all of this evidence into a hearing-ready packet tailored to Tennessee's rules.
