Voluntary e-invoicing April 2024; mandatory to be confirmed for October 2024
Sultanate of Oman Tax Authority has confirmed its plan to introduce VAT electronic invoicing via a formal Request for Information tender request. “The plan is to open e-Invoicing to VAT registered taxpayers in Oman on a voluntary basis to start, and then subsequently on a compulsory basis,” the RFI added. A voluntary launch period between April and September 2024 is envisaged; followed by mandatory e-invoicing from October 2024.
It is not clear if Oman will introduce a pre-clearance Continuous Transaction Control e-invoicing model, whereby the tax authorities reveive and then validate the invoice before it being recognised as a VAT invoice.
Oman introduced VAT in April 2021. It was the fourth of the six Arab Gulf states to roll out VAT as part of new Customs and VAT union. So far, only Saudi Arabia e-invoicing has also been introduced at the end of 2021. UAE e-invoicing is expected for 2025.
Bahraini e-invoicing may follow shortly, with the tax offices now completing research on invoice use.
