A value-added tax is a consumption tax that is levied on the value added at each stage of a product's production and distribution. VAT is similar to, and is often compared with, a sales tax. VAT is an indirect tax, because the consumer who ultimately bears the burden of the tax is not the entity that pays it. Specific goods and services are typically exempted in various jurisdictions.
Products exported to other countries are typically exempted from the tax, typically via a rebate to the exporter. VAT is usually implemented as a destination-based tax, where the tax rate is based on the location of the producer.
