For taxpayers subject to the standard 15% tax rate, the return deadline is 30 April 2025 (i.e., four months after year-end). For small businesses subject to the 3% flat tax rate, the deadline was 30 March 2025 (i.e., three months after year-end). Current conditions for the flat tax rate include that registered capital does not exceed OMR 60,000 and gross income does not exceed OMR 150,000.
