Residents in Williamson County have likely received a card in the mail with a new home valuation and may be wondering how it will affect their tax bills for the year.

The county sent out results of its 2021 property reappraisals in recent weeks with new valuation that will determine how much residents will pay in taxes. Property reappraisals are made every five years in Williamson County and were last conducted in 2016.

The reappraisal process coincides with city budget season, and as a result of the reappraisals, Franklin and Brentwood will be adjusting their tax rates. The city of Brentwood has proposed lowering its tax rate from $0.36 per $100 home valuation to $0.29. The city of Franklin has proposed a rate change from $0.41 to $0.32. Both cities are expected to approve tax rates before the end of June.

While the tax rate will be lowered, the effective rate for both cities will remain the same. State law requires the city to adjust tax rates when reappraisals are made to ensure no additional tax revenue is collected from residents as a result. Because the values of many properties in Williamson County rose, both cities will lower their rates, but will still collect approximately the same amount as last year.

For example, in Brentwood, the average property value increased by about 23% and the property tax rate has been adjusted to reflect that average, meaning residents who saw an increase of more than 23% may pay slightly more in property taxes, while properties that saw a lower increase may pay less.


Residents who believe the assessment may be inaccurate can contact the Williamson County Property Assessor with questions at 615-790-5708. Those who wish to appeal their valuation can do so by calling during the first week of June to schedule a time to appear before the Williamson County Board of Equalization.
