Mo. Rev. Stat. § 52.250
The collectors in third class counties shall collect a fee of one-half of one percent and the collectors in fourth class counties shall collect a fee of one percent of all current taxes collected, including current delinquent taxes, exclusive of all current railroad and utility taxes collected, as compensation for mailing the statements and receipts. All fees collected pursuant to this section shall be collected on behalf of the county and shall be paid into the county treasury. Collectors in third and fourth class counties are entitled to collect such fees immediately upon an order of the circuit court under section 139.031, RSMo. If the protest is later sustained and a portion of the taxes so paid is returned to the taxpayer the county shall return that portion of the fee collected on the amount returned to the taxpayer.
