According to Resolution 279/2019, the Peruvian tax administration (SUNAT) requires taxpayers with revenues over a certain threshold to start issuing electronic invoices and receipts. For most taxpayers, that obligation began on 1 January 2021; however, small to medium taxpayers with annual revenues between 23 and 75 Fiscal Units (1,008 to 75,600 US dollars) will have until 1 January 2022 to start issuing electronic invoices and until 1 April 2022 to begin issuing electronic receipts. Micro taxpayers with annual revenues below 23 Fiscal Units will have until 1 April 2022 to begin issuing electronic invoices and until 1 June 2022 to comply with the e-Invoicing obligations.
