Modifies provisions relating to property taxes

SB 1522 revises Missouri's property tax assessment rules, directly affecting homeowners, businesses, farmers, and airport operators. Key changes include setting a 5% tax rate for solar equipment installed before August 2022, reducing the tax rate for agricultural crops to 0.5%, and allowing airport property owners to deduct their construction costs from taxable value. The bill also establishes a new two-year assessment maintenance plan process requiring county approval and clarifies how computer-assisted valuations must be justified in disputes. These provisions aim to modernize tax calculations while maintaining specific exemptions for certain property types.
