Oman Tax Authority
E-Invoicing Mandate.
Oman's Tax Authority (OTA) is progressing towards a mandatory e-invoicing framework. ClayDesk tracks OTA guidance and prepares enterprises operating in Oman for compliance ahead of mandate activation.
Oman's e-invoicing trajectory.
Oman introduced VAT in April 2021, and the OTA is developing an e-invoicing mandate consistent with the broader GCC digital tax transformation agenda.
The OTA has signalled intent to introduce structured e-invoicing requirements for VAT-registered businesses. The framework is expected to follow a phased rollout similar to neighbouring jurisdictions, with large taxpayers subject to earlier mandatory dates.
Enterprises already operating compliant e-invoicing infrastructure for UAE or Saudi Arabia are well-positioned to extend that infrastructure to Oman when the mandate activates. ClayDesk designs Oman compliance as an extension of existing GCC infrastructure — not a separate implementation.
