Tax bills are mailed to taxpayers by December 1 of the tax year. Bills are due upon receipt. The latest you can pay without paying interest for a late payment or a penalty is by December 31 of the tax year. Failure to receive a tax bill does not relieve a taxpayer of the obligation to pay timely (Section 52.240 RSMo). Payments received on or after January 1st of the year following the year for which tax was assessed must include late payment interest and penalty in accordance with Sections 52.590, 139.100 and 140.100 RSMo. 

The tax rate is established initially by a vote of the residents within the boundaries of the taxing subdivision. Property tax rates are monitored and approved annually by the State Auditor. Examples of these taxing subdivisions would include public schools, fire districts, library district, ambulance district and cities.

Also, your taxes may increase because:

- Your rates are determined by the voters and may have increased.

- Values are determined by the assessor per NADA - & may have increased.

- You have a new vehicle

A duplicate receipt is available from the Collector's Office for a statutory fee of $1.
