- Oman’s Tax Authority has issued Decision No. 189/2026 to amend VAT regulations and introduce mandatory electronic invoicing.
- VAT-registered businesses must issue, transmit, and store invoices in an approved structured electronic format (XML under PINT OM or PDF/A-3); paper invoices, plain PDFs, and emailed images will no longer be valid.
- Implementation will be in two phases: 1 April 2027 for businesses with annual supplies over OMR 5 million, and 1 October 2027 for all remaining VAT-registered businesses.
- A voluntary pilot with selected large taxpayers will begin at the end of August 2026.
- The measure aims to digitalize tax processes, improve VAT compliance and transparency, and reduce invoice fraud.
