Is e-invoicing mandatory in Oman yet?
Table of Contents
As of August 2026, e-invoicing is entering its initial implementation stage and is not yet mandatory for every VAT-registered business in Oman.
The Oman Tax Authority's current rollout plan consists of four phases. The first phase covers 100 selected large VAT-registered companies, with implementation beginning in August 2026.
The second phase covers all large VAT-registered taxpayers and begins in February 2027. The third phase covers the remaining VAT-registered taxpayers, with implementation beginning in August 2027.
The fourth phase covers government institutions and entities, with implementation scheduled to begin in February, although the specific year has not yet been announced by the OTA.
Businesses that are not yet in the mandatory rollout can also adopt e-invoicing voluntarily, subject to the applicable requirements and support provided by the Tax Authority.
The OTA has stated that rollout participants are contacted ahead of their onboarding, giving businesses time to prepare their systems and complete the necessary implementation work.
