Argentina’s tax authority ARCA has introduced General Resolution 5824/26, expanding mandatory e‑invoicing to new sectors and launching a monthly electronic settlement system effective 1 July 2026. The resolution also provides pre‑filled VAT returns for Simplified Tax Regime taxpayers, with invoicing data automatically populating annual returns. Electronic invoices will be available via ARCA’s “My Receipts” portal and integrated into the Digital VAT Ledger.

The article reports that SAP’s newly approved Platform Agreed (PA) meets French e‑invoicing requirements, but users remain concerned about integration and fixed deadlines. It notes that the reform is already in place in Italy and Mexico and will be extended across the EU in the coming years, with full implementation in France scheduled for 2026.

Belgium will require all VAT‑registered businesses to exchange B2B invoices electronically via the Peppol network using the BIS Billing 3.0 standard from 1 January 2026. A Q1 2026 grace period allows technical setup without penalties, while non‑resident firms and B2C transactions are exempt. Penalties for non‑compliance start at €1,500 and increase to €5,000 for subsequent offences.

Greek tax authority AADE has postponed the mandatory B2B e‑invoicing launch to 2 March 2026, with a two‑month soft launch ending 2 May 2026 for large resident businesses. All other resident taxpayers must adopt the system from 1 October 2026, and a new penalty regime and early‑adopter incentives have been announced.

Germany’s national e‑invoicing mandate requires all businesses to receive structured invoices from January 2025 and to transmit them by revenue thresholds, with full coverage by January 2028. The system accepts XRechnung, ZUGFeRD and Peppol BIS formats, all EN 16931 compliant, and mandates 8‑year electronic archiving under GoBD. Non‑compliance can trigger VAT deduction denial, GoBD violations and administrative fines.

Brazil’s new Technical Notes mandate that invoices and payments be linked under the split payment framework, requiring integration between electronic tax documents (DF‑e) and payment data. The system will be tested from 6 April 2026 and go live on 4 May 2026, with XML and invoicing processes needing updates to include transaction data for automatic withholding of IBS and CBS.

The article argues that compliance with country mandates should be seen as a baseline, not the ultimate goal. It emphasizes that true invoicing success lies in data governance and ensuring invoices are accurate, fraud‑free, and defensible in accounting, rather than merely passing XML validation. The author highlights mandates in Poland, France, Belgium, Germany, and Saudi Arabia, and calls for a holistic approach to tax determination and data integrity.
