¿Me aplica?
Dos preguntas. La regla del establecimiento permanente es donde la mayoría de las empresas extranjeras se equivocan.
Is your business established in Oman (registered office, branch or fixed establishment)?
How large is your Oman business?
Oman: likely outside the issuing mandate — watch e-reporting / cross-border
Whether non-established businesses fall in scope is unconfirmed – the OTA has not published a position, and advisers report that VAT-registered persons are in scope regardless of location. If you are VAT-registered in Oman, assume you are in scope until the OTA says otherwise.
Not in scope for Oman
With no establishment and no registration or trade in Oman, the mandate doesn't apply to you today. Revisit this if you open a branch, warehouse or start supplying into Oman.
In scope – Oman first wave (from 1 April 2027)
As a larger established business with annual supplies above OMR 5 million (approx. USD 13 million), your obligation begins 1 April 2027. Start platform selection and ERP mapping now.
In scope – Oman later phase (from 1 October 2027)
With annual revenue of OMR 5 million or less, your issuing obligation begins 1 October 2027. There is no published receiving duty before then, but your larger suppliers go live from 1 April 2027 – don't wait for your own deadline to prepare.
