Mo. Rev. Stat. § 271.180

When the taker-up shall have filed the receipt of the county treasurer with the clerk of the county commission for the full amount which he is required to pay into the county treasury, said clerk shall charge the treasurer with the same, and write in the margin of the record, opposite the amount with which the taker-up stands charged, the word "paid"; or if the taker-up shall not pay into the county treasury the full amount required by law, the clerk shall only give him credit for the amount paid, and charge the same to the treasurer accordingly.
