E-invoicing is enjoying increased momentum in South America, and Paraguay is rapidly following the lead of its neighbouring countries with developments in the e-invoicing terrain. Companies that are on a ‘designated list’ shared by the tax authorities will be obligated to use e-invoicing by 2 January 2023. Further company lists will form the basis for each phased period, of which there will be 10 stages, found here. The final phase is expected in October 2024. E-invoicing in Paraguay shares key characteristics with other Latin American states, including the requirement to use an XML format, as well as the obligation for a digital signature.
