VAT in Oman, in plain English

Oman charges 5% VAT filed quarterly with the Oman Tax Authority (OTA), with Fawtara e-invoicing phasing in.

Registration threshold: OMR 38,500 mandatory (OMR 19,250 voluntary). Returns are filed as the VAT return (OTA e-portal), and Oman uses Fawtara (Oman's Peppol-based e-invoicing programme, phasing in). This tool is for quick estimates — always confirm the exact rate and treatment of your supplies with Oman Tax Authority (OTA) or a qualified local tax professional.
