Office Information

Tax bills are usually mailed in late November and are delinquent after December 31st each year.  If you have not received your current year tax bill by December 1st, please contact the Collector’s office regarding your current tax status.


If you have delinquent taxes, you must pay the delinquent taxes before paying the current taxes that are due.


Jefferson County taxpayers will now be able to utilize the Missouri Department of Revenue on-line renewal system for license renewal for your automobiles.  This was made possible by a joint effort between the Missouri County Collectors and the Missouri Department of Revenue.
