< Back to E-Invoicing Overview
Oman has introduced e-invoicing as part of its VAT implementation and broader tax modernization efforts. The country is gradually transitioning to digital invoicing to improve compliance, reduce fraud, and streamline business transactions.
The Omani government is expected to mandate e-invoicing in the near future, aligning its system with international best practices. Businesses adopting e-invoicing voluntarily can benefit from automation and improved financial reporting.
Regulatory authority
The Oman Tax Authority (OTA) oversees e-invoicing compliance and future implementation.
E-invoicing requirements
Currently, e-invoicing is voluntary, but the government is working toward mandatory adoption.
Accepted invoice formats
Future e-invoicing regulations are expected to use XML-based formats compatible with VAT reporting.
Transmission channels
Invoices will be submitted through a government-approved electronic invoicing platform.
Digital signatures
Digital signatures are expected to be required for compliance and authentication.
Archiving requirements
Invoices must be stored for at least five years under Omani tax regulations.
