Tax Filing & Returns in Oman

Preparation and filing of the Omani tax cycle with the OTA: the annual corporate income tax return (15% of net taxable income, or 3% for a qualifying small enterprise), reported as due within four months of the end of the accounting period; the VAT return for the quarterly standard tax period at the 5% basic rate, reported as due within 30 days of the end of the period; and the monthly withholding-tax remittance — 10% on Omani-source payments to non-residents for royalties, research and development consideration, computer-software use or rights, management fees, dividends, interest and service fees, remitted no later than the fourteenth day of the month following the month in which the payment was made or credited, subject to double-tax-treaty relief. A reported Royal Directive of January 2023 suspends withholding on dividends and interest to non-residents, but the OTA withholding-tax page still lists both — the current position must be confirmed before advising. Two forward obligations to plan for: the Fawtara e-invoicing mandate (reported Phase 1 from 1 April 2027 for annual supplies over OMR 5 million and Phase 2 from 1 October 2027 below that, after a voluntary pilot from August 2026) and, for multinational groups with consolidated revenue of at least EUR 750 million, the Pillar Two 15% domestic minimum top-up tax / income inclusion rule introduced by Royal Decree 70/2024 for fiscal years from 1 January 2025. Ordinary SMEs are out of scope of both today.
