Missouri Revised Statutes Title IV. Executive Branch § 37.1094. Local governments may participate in database, procedure--electronic transmission of data--financial reimbursement, when

1. A municipality or county may choose to voluntarily participate in the Missouri local government expenditure database, or, if a requisite number of residents of a municipality or county request the municipality or county to participate, such jurisdiction shall participate in the Missouri local government expenditure database. The requisite number of residents requesting participation shall be five percent of the registered voters of such jurisdiction voting in the last general municipal election, as described under section 115.121, but in no case shall the requisite number be fewer than fifty residents. Residents may request participation by submitting a written letter by certified mail to the governing body of the municipality or county and the office of administration. Multiple residents may sign one letter, but the number of requests from residents shall include all requests from all letters received. Upon receiving such a letter, the municipality or county shall acknowledge receipt thereof to the resident and the office of administration within thirty days. After receiving the requisite number of requests, the municipality or county shall begin participating in the database but shall not be required to report expenditures incurred before one complete six-month reporting period described under subsection 2 of this section has elapsed.

2. Each municipality or county participating in the database shall provide electronically transmitted information to the office of administration, in a format the office requires, for inclusion in the Missouri local government expenditure database regarding each of the municipality's or county's expenditures biannually. Information regarding the first half of the calendar year shall be submitted before July thirty-first of such year. Information regarding the second half of the calendar year shall be submitted before January thirty-first of the year immediately following such year.

3. Notwithstanding subsection 1 of this section, no submission shall be required for any expenditures incurred before January 1, 2023.

4. The office of administration shall provide each municipality and county participating in the database with a template, in the format described under section 37.1092, for the purpose of uploading the data. The office of administration shall have the authority to grant the municipality or county access for the purpose of uploading data.

5. Upon appropriation, the office of administration shall provide financial reimbursement to any participating municipality or county for actual expenditures incurred for participating in the database.
