Appeal Process
Think Your Assessment Is Wrong? Here’s How to Appeal
You have the right to challenge your property assessment. Most appeals start and end with an informal review — it’s faster and less formal than you might think.
Informal Review with Property Assessor
(423) 323-6455Start here. Call the Property Assessor's office to schedule an informal review. Bring comparable sales data, photos of your property, and your reappraisal notice. Many appeals are resolved at this level without going further.
Board of Equalization
If the informal review doesn't resolve your concern, you can appeal to the Board of Equalization — an independent board that holds formal hearings, typically in June. You'll present the same evidence. Contact the Assessor's office to schedule a hearing.
State Board of Equalization
(615) 401-7883Final level of appeal. If you disagree with the local Board of Equalization decision, you can appeal to the State Board. Most people never need this step.
Understanding Your Bill
How Your Bill Is Calculated
Tennessee only taxes 25% of your home’s value. Once you understand the formula, the numbers start to make more sense.
Step 1
Appraised Value
What the Assessor says your home is worth
Step 2
× 25% = Assessed Value
Tennessee only taxes 25% of residential property
Step 3
Assessed ÷ 100 × $1.6129
= Your estimated county property tax (2025-26 rate)
Example
$270,000 appraised value
× 25% = $67,500 assessed value
$67,500 ÷ 100 × $1.6129 = $1,088.71 estimated county tax (2025-26 rate)
Calculate Your Property Tax
Estimate only — not tax advice. This calculator is for informational purposes only. Uses the 2025-26 county tax rate of $1.6129. Does not include city taxes or special assessments. Contact the Trustee at (423) 323-6464 for official calculations.
What Happened
What Happened With the 2025 Reappraisal
Tennessee law requires counties to reappraise property values every four years. Home prices between 2021 and 2024 drove values up significantly. The average increase across Sullivan County was 62%.
The Commission did not raise taxes. The certified tax rate dropped from $2.4962 to $1.6129 for the 2025-26 tax year — a reduction designed to keep overall tax revenue neutral.
The Commission voted 22-0 to adopt the certified rate with no increase. Joyce voted for no increase.
But if your property went up more than 62%, your bill may still be higher even at the lower rate. That’s why understanding your options — appealing your assessment or applying for tax relief — matters.
