Sales tax is collected by the retailer when the final sale in the supply chain is reached via a sale to the end consumer. End consumers pay the sales tax on their purchases. Businesses issue resale certificates to their sellers when buying business supplies/inputs that will be resold since sales tax is not due. Tax jurisdictions do not receive the tax revenue until the sale is made to the final consumer.
VAT (Value-Added Tax) is collected by all sellers in each stage of the supply chain. Suppliers, manufacturers, distributors and retailers all collect the value added tax on taxable sales. Suppliers, manufacturers, distributors, retailers and end consumers all pay the VAT on their purchases. Businesses must track and document the VAT they pay on purchases that will be resold in order to receive a credit for the VAT paid on their tax return. Tax jurisdictions receive the tax revenue throughout the entire supply chain as opposed to at the sale to the final consumer chain.
