Proposes a constitutional amendment replacing individual and corporate income tax, and sales and use tax with a sales tax on retail sales of new tangible property and taxable services

HJR 50 proposes a constitutional amendment to replace Missouri's individual and corporate income taxes, corporate franchise taxes, and all existing state sales and use taxes with a new 5.11% sales tax on retail purchases of new tangible property and taxable services. The bill would exempt business purchases (for resale or operations) and investment property from this tax, while requiring the state to provide annual sales tax rebates to "qualified families" based on federal poverty guidelines. Revenue lost from eliminating income taxes must be replaced by this new sales tax, with adjustments allowed if revenue gaps exceed 1% of prior year collections. The amendment requires voter approval through a special election, as it fundamentally restructures the state's tax system.
