What is Reverse Sales Tax?
Sales tax is a consumption tax charged on retail sales. Consumers bear the financial cost of sales tax at checkout, while merchants collect and remit these funds to state tax authorities. Reverse sales tax calculation extracts the original price before tax was added.
Sales tax vs. value-added tax (VAT)
While US sales tax applies only at the final retail sale, European VAT and Canadian HST apply to every stage of production. For detailed formula derivations across all tax types, consult our Reverse Tax Formula & Math Guide.
