Because of historic high property values, Hamilton County’s property tax rate will decrease to a historic low.

County properties will be taxed at a rate of $1.5157 per $100 of assessed value, which is a quarter of a property’s appraisal value, officials announced Tuesday. That’s the lowest rate in the county since 1941, county Mayor Weston Wamp said at a press conference.

It’s around a 70-cent decrease from the previous rate of $2.23. Per state law, the rate was reduced so that the county would not receive a large increase in revenue simply because property values went up. The new certified rate is calculated to bring the county the same amount of revenue as before, as property values rise. If officials want more revenue, they need to raise taxes from the new certified rate — which county officials have indicated they do not intend to do.

Because properties experience different increases in assessed value, around a third of county property owners can expect to pay significantly more in property taxes than they did last year given higher values, county Assessor Marty Haynes said.
