Knox County property tax

Knox County set new values for every property in 2026, and both tax rates came down with them. A Knoxville home gets two bills, one from the county and one from the city.

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, $1.0158.

The Knoxville rate is $2.4114. At that rate a home pays $602.85 a year for each $100,000 of appraised value. $100,000 × 25% is $25,000 of assessed value. $25,000 ÷ 100 × $2.4114 is $602.85.

These are the 2026 rates, as the City of Knoxville published them. 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 October 1. 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.

The Trustee has five more offices, in East, North, West and South Knoxville and in Farragut. The City of Knoxville sends its own bill for the city tax. It is payable from October 1 and late from March 1, and the city takes 1% off a bill paid in full by the end of October. The city’s Property Tax Office is in Suite 453 of the City-County Building. Its phone number is (865) 215-2084. The 2026 county rate is $1.0158 and the Knoxville city rate is $1.3956. In 2025 they were $1.554 and $2.1556.

You can ask the Assessor to look at your value again. This is the informal review. It costs nothing. Knox County takes informal reviews in a reappraisal year only. In another year, the first step is the Knox County Board of Equalization.

When to file

Knox County takes informal appeals in a reappraisal year. 2026 was a reappraisal year, and the window for homes closed on May 29, 2026. The next reappraisal is in 2028.

How the review works in Knox County

In a reappraisal year you file an informal appeal on a form on the Assessor’s website. The Assessor emails you when the appeal is in its system. In 2026 the Assessor sent the results by notice in mid to late June. In any year you can ask the Assessor for a field review if a detail of your property is wrong.

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 Knox County Board of Equalization. The Assessor’s calendar has the Board in session through June. For the 2026 reappraisal, the Assessor said the Board met in July. After the county Board, you can appeal to the State Board of Equalization. See the appeal dates for every Tennessee county.

Knox County set new values for every property in 2026. The next reappraisal is in 2028, on the state Comptroller’s schedule.

Knox County reappraises every two years. The first year is for field work. In the second year the Assessor sets the new values and mails a notice to every owner.

The county is on a 2-year cycle.

Your value generally stays the same between reappraisals unless the property changes or a review changes it.

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.
