Modifies provisions relating to sales tax receipts

SB 958 requires businesses with over $500,000 in annual sales to clearly display the total sales tax rate (including state and local taxes) and any tariffs on all sales receipts and invoices, whether paper or electronic. This applies to every transaction where a receipt or invoice is provided, as defined in Missouri law. The bill defines "sales receipt" and "sales invoice" to standardize these documents. It aims to increase transparency about tax and tariff costs for consumers at the point of sale.
