Modifies provisions relating to taxation

SJR 56 proposes a constitutional amendment to eliminate Missouri's state income tax on individual earnings after 2029, replacing it with a sales tax system. It prohibits the state from imposing an income tax on individuals for tax years beginning in 2030 or later (with a 3% cap until 2029), requires a sales tax on most goods and services (capped at 5% until 2030), and directs a portion of sales tax revenue to school districts to maintain funding levels from 2022-2026. The amendment exempts essential items like food, medical care, education, and agricultural products from the sales tax. This change would directly affect all Missouri residents by shifting their primary tax burden from income to sales.
