How Sumner County figures your tax bill
Hendersonville and Gallatin are the largest cities in Sumner County. Each city adds its own rate to the county rate.
The county starts with your appraised value. That is what the Assessor says your property is worth. A home is taxed on 25% of it. That part is the assessed value. The tax rate is a charge on each $100 of assessed value.
Appraised value × 25% = assessed value
Assessed value ÷ 100 × tax rate = tax for the year
A property inside a city pays the county tax and the city tax. The table shows the two rates together. A property outside a city pays the county rate, $1.421.
The Gallatin rate is $1.9505. At that rate a home pays $487.63 a year for each $100,000 of appraised value. $100,000 × 25% is $25,000 of assessed value. $25,000 ÷ 100 × $1.9505 is $487.63.
| City or district | 2025 rate for each $100 assessed | A home’s tax for each $100,000 appraised |
|---|---|---|
| Gallatin | $1.9505 | $487.63 |
| Outside a city | $1.421 | $355.25 |
| Goodlettsville | $1.9278 | $481.95 |
| Hendersonville | $2.0093 | $502.33 |
| Millersville | $2.0908 | $522.70 |
| Mitchellville | $1.6744 | $418.60 |
| Portland | $2.321 | $580.25 |
| Westmoreland | $2.251 | $562.75 |
| White House | $2.3171 | $579.28 |
These are the 2025 certified rates, the latest the state has published. A commercial property is taxed on 40% of its appraised value, at the same rates.

When the bill comes and when it is due
The county tax can be paid from the first Monday of October. Pay in full by the last day of February to avoid interest. The Assessor sets your value. The Trustee sends the bill and takes the payment.
Interest starts on March 1. The Trustee takes up to five part payments on a bill, by check or cash.

The Sumner County Assessor of Property
John M. Hurt is the Assessor of Property for Sumner County. The office sets the appraised value of every property in the county. It does not set the tax rate, and it does not collect the tax.

Sumner County’s property records are on the state’s Tennessee Property Assessment Data site, assessment.cot.tn.gov. Choose Sumner County, then search by owner, address or parcel. The record shows the appraised value, the land and the building details.
Read the building details on your record. A wrong square footage, an extra bathroom or a basement marked as finished raises the value. If a detail is wrong, tell the Assessor’s office.
If your appraised value looks too high
You can ask the Assessor to look at your value again. This is the informal review. It costs nothing.
When to file
In 2026 the informal reviews ran from May 4 to May 29. The Assessor expects the next ones to begin in May 2027.
How the review works in Sumner County
Call the Assessor’s office at (615) 452-2412 or visit it. In the review season the Assessor also has an online form. The Assessor asks for sales of similar properties in the immediate area from the last three years, a recent private appraisal, and photos. The office contacts you with the result. An informal review is not an appeal.
A review can lower your value, leave it the same or raise it.
What to send
Send facts about the value. The Assessor sets the value and does not set the tax rate, so a complaint about the bill does not help.
- Recent sales of similar homes near yours, for less than your appraised value.
- Errors in your record, such as the wrong square footage or a basement marked as finished.
- Photos and repair estimates for problems that lower the value.
- Your closing statement, if you bought the home for less than its appraised value.
More evidence helps. A price estimate from a website is not a sale, and an assessor does not count it. See how to find comparable sales and the Tennessee appeal guide.
If the Assessor keeps your value
The next step is the Sumner County Board of Equalization. The Board meets from June 1. Call the Assessor’s office at (615) 452-2412 to make an appointment. You must appeal to the county Board before you can appeal to the State Board. In 2026 the last day to appeal to the Board was June 12. After the county Board, you can appeal to the State Board of Equalization. See the appeal dates for every Tennessee county.

Tax relief and tax freeze in Sumner County
Tennessee has programs that lower the tax for some homeowners. They do not change your appraised value. You can use a program and also ask for a review of your value.
Tax relief. For owners age 65 or older, owners with a disability, and disabled veterans or their surviving spouses. For the first two groups, the combined 2025 income of the owners and the applicant’s spouse must be $38,470 or less. The program pays part of the tax as a credit, and you do not repay it.
Tax freeze. For owners age 65 or older by December 31, 2026. The combined 2025 income must be $48,550 or less. The program holds the tax on your home at the amount for the year you qualify. The county’s freeze covers the county tax. Gallatin, Goodlettsville, Hendersonville, Portland, Westmoreland and White House each have a freeze for the city tax. The income limit is $48,550 in each.
These are the limits for the 2026 tax year. Apply at the office of the Trustee by April 5, 2027. You can apply when you receive your 2026 tax bill. The phone number is (615) 452-1260.
The Trustee takes appointments by phone. The Trustee runs the freeze for the county and for some of its cities. You must qualify again each year.
When Sumner County reappraises
Sumner County set new values for every property in 2024. The next reappraisal is in 2029, on the state Comptroller’s schedule.
The county is on a 5-year cycle. You can ask for a review in any year. You do not have to wait for the next reappraisal.
Your value stays the same between reappraisals unless the property changes or a review changes it. A sale does not reset it. If you bought your home for less than its appraised value, the county keeps the higher value until you ask for a review. See how a purchase price can lower your value.
A reappraisal does not raise the county’s total tax by itself. State law makes the county set a rate that brings in the same total as before. The county commission then votes on the rate for the year.
