For Omani businesses getting ready for Fawtara.

Oman is introducing e-invoicing on the same Peppol five-corner model as the UAE, so the work One does for the UAE carries over.

Oman e-invoicing (Fawtara): the Oman Tax Authority started a pilot in August 2026 with about 100 large taxpayers, on a Peppol five-corner model with accredited providers. Wider phases are indicated for 2027 and 2028, but dates beyond the pilot are not final.
