Authorizes counties to enact an earnings tax to replace county real property and personal property taxes

This bill authorizes Missouri counties to vote on replacing their existing real and personal property taxes with a new earnings tax. If approved by local voters, the tax would apply to wages, salaries, commissions, and business profits earned by both residents and nonresidents working within the county. The legislation includes specific exemptions for various nonprofit organizations, religious groups, and certain types of insurance and retirement funds. Ultimately, the change requires a direct vote by county residents to ensure the new tax generates revenue equal to what was previously collected from property taxes.
