What to check on your notice
The typical Cannon County home gained 5.1% in the year to January 2026. A notice that rose far more than that, or a value above what similar homes nearby actually sold for, is the usual starting point for an appeal.
How a Tennessee appeal works
Values in Cannon County are set by the local county assessor of property, and the appeal starts there. The rules below apply statewide; your notice has the exact dates and office for your property.
| Who sets the value | County assessor of property. Each county has an elected assessor of property who values real estate. The State Comptroller's Division of Property Assessments oversees the counties. |
|---|---|
| Valuation date | January 1 |
| Your notice | Assessment Change Notice |
| Deadline | The county Board of Equalization starts its annual session on the first business day of June. The assessor must mail change notices at least 10 days before it starts, and the published notice states the last day the board accepts appeals. Appeal to the county board by that date, or the value can become final for the year. |
| First step | Informal talk with the county assessor, then a hearing before the county Board of Equalization. |
| If you still disagree | Appeal to the Tennessee State Board of Equalization by August 1 of the tax year, or within 45 days of the date notice of the county board action was sent, whichever is later. Then Chancery Court may be available (not confirmed here). |
| Can the value go up? | Not confirmed. The State Board says an increase after a countywide reappraisal does not by itself invalidate the assessment or justify a change. |
Reading this in fall 2026? The 2026 deadlines have passed (county board from June 1, 2026; State Board by August 1, 2026 or 45 days after the county decision, whichever is later). Your next chance is the 2027 county Board of Equalization, which opens the first business day of June 2027. Watch for your assessment change notice in spring 2027 and file with the county board before its published last day. If you appealed to the county board this year and lost, check your decision date now, because the State Board window can run 45 days from that notice.
- You must appeal to the county board first. Skipping it can make the assessment final for that year, unless you were never properly notified of the increase.
- Every county is on a four, five, or six year reappraisal cycle. The big value jumps come in the reappraisal year, so check when your county reappraises.
- The State Board can accept a late appeal with reasonable cause up to March 1 of the following year.
Find your local office in the Tennessee Comptroller, State Board of Equalization (contact your county assessor to appeal to the county board).
Building a Cannon County case
A citywide index shows the trend. Your case needs your house. Cannon County is part of the Nashville-Davidson--Murfreesboro--Franklin metro, but your evidence should be local. Sales a few streets away usually beat sales across the metro.
- Bring sales of similar nearby homes close to January 1 and photos of condition issues.
- Compare your new value to last year's on the change notice, since the notice must show both.
- Keep the date on any county board decision notice, because it sets your State Board deadline.
