UAE's Ministry of Finance has extended the deadline for large taxpayers to appoint an Accredited Service Provider (ASP) to 30 October 2026, while keeping the mandatory e‑invoicing go‑live dates unchanged. Large businesses must issue e‑invoices via the Peppol network in PINT AE format from 1 January 2027, with smaller businesses and government entities following in July and October 2027 respectively. The amendment also introduces a white‑label mechanism for ASP accreditation, allowing UAE‑based firms to partner with international technology providers.
