Greece has introduced a three-layer digital tax framework that combines real‑time reporting via myDATA, a structured B2B e‑invoicing mandate, and an e‑transport system for goods movement. The B2B e‑invoicing requirement becomes mandatory on March 2 2026 for firms with revenue above €1 million and on October 1 2026 for all other businesses, while myDATA has been compulsory since 2021. Early adopters receive significant tax incentives, and non‑compliance triggers steep penalties.

This guide details the Standard Audit File for Taxation (SAF‑T) structure, outlining its four main sections—Header, MasterFiles, GeneralLedgerEntries, and SourceDocuments—and the reference data tables required for compliance. It explains how each transaction must link back to MasterFiles and highlights common validation errors, with specific reference to Luxembourg’s FAIA variant and its tax rates.

On 20 March 2026 Angola’s AGT exempted taxpayers who issue electronic invoices from the obligation to submit SAF‑T files, simplifying compliance for those already on the e‑invoicing system. The exemption covers large taxpayers, government suppliers and, from 1 October 2026, all remaining VAT‑regime taxpayers, while accounting and inventory SAF‑T obligations remain unchanged.

The article explains how UAE’s new e‑invoicing regime requires more than just XML formatting; it demands accurate interpretation of key data fields. Field 5, an 8‑character binary sequence, flags transaction scenarios such as free‑zone or export, while Field 11, the seller’s electronic address, identifies the network endpoint for responses. Correctly mapping these fields is essential for compliance and accurate VAT processing.
