Oman e-Invoicing 2026: Key Requirements, Timeline, and How Businesses Should Prepare

  • Oman is implementing a national e-invoicing program to replace paper and PDF invoices with standardized electronic invoices created and exchanged through approved systems.
  • E-invoices will become the only legal document, must be issued directly from approved systems, require digital certificates, and must be archived for 10 years.
  • The 5-corner model outlines secure invoice exchange between suppliers, service providers, buyers, and the tax authority, with strict accreditation criteria for service providers.
  • The rollout will occur in four phases from August 2026, starting with large VAT-registered companies and eventually including all VAT taxpayers and government entities.
