Establishes the "Missouri Innovation, Public Safety, and Accountability Act"

Added a specific definition for 'Baseline year' that allows municipalities to use a different year if economic activity taxes decrease or if the area suffered severe damage from a natural disaster between May 1, 2003, and May 10, 2003.

Modified the definition of 'Central business district' to include a requirement that the area must have a median household income of $62,000 or less based on Census data, alongside existing criteria about building age and vacancy.

Changed the bill title and purpose from a broad 'Innovation, Public Safety, and Accountability Act' to a specific 'Financial Incentives for Economic Development' act, indicating a shift in legislative intent.

Added a requirement that at least 50% of existing buildings in the central business district must be over 35 years old or vacant lots must have structures over 35 years old to qualify as a central business district.

Added specific operational rules stating that participation is voluntary and no local legislative act is needed to maintain zone designation.

Defined the required contents of a 'master plan,' including geographic boundaries, property identification, and reinvestment strategies.

Established a 45-day deadline for the state department to review and approve or deny a city's application.

Corrected formatting and line breaks in definitions and section numbering to finalize the bill text.

The bill now includes HB 2531, adding three new sections (620.6027, 620.6030, 620.6033) to the original text.

The term 'Innovation district' was replaced with 'Missouri innovation zone,' and the definition was updated to include 'qualified Missouri main street district' instead of just 'Missouri main street district.'

New financial definitions were added, including 'Baseline,' 'Net-new local revenue,' 'Net-new property tax revenue,' and 'Net-new state revenue,' to clarify how economic impact is measured.

The term 'Innovation district master plan' was renamed to 'Master plan,' and its purpose was updated to request designation and certification of a Missouri innovation zone.

The definition of an 'Application' was broadened from a specific submission for incentives to a general request for designation, certification, approval, or other actions under the new sections.
