Property Tax

Property taxes of residents who live within Slidell City limits are
assessed by the St. Tammany Parish Assessor’s Office and
collected by the St. Tammany Parish Sheriff’s Office.

The St. Tammany Parish Sheriff’s Office collects and has collected city taxes since 1998. Prior to that year, city taxes were collected by the City of Slidell Finance Department. The amount of taxes paid is determined by a tax millage applied to your property’s assessed value.
