This article explores Portugal’s VAT reverse charge mechanism, which impacts domestic supplies of goods and services. The reverse charge applies to all transactions by non-resident businesses (EU or non-EU) provided conditions are met. This shift in responsibility for paying VAT from the supplier to the recipient can offer cash flow advantages, as they can potentially delay VAT payment until they file their VAT return. However, navigating the regulations and ensuring compliance requires a clear understanding of the reverse charge mechanism. Our team of Portuguese VAT specialists can assist businesses in determining applicability, developing VAT compliance strategies, and maintaining proper records under the reverse charge system.
