Corporate Income Tax (CIT) in Oman is regulated by Royal Decree No. 28/2009 and enforced by the Tax Authority. The general rate of tax is 15% on taxable income for the majority of businesses, with lower provisions for small and medium enterprises (SMEs).

Oman has a straightforward and friendly tax regime, with no inheritance, net wealth, payroll, or capital gains taxes. Timely filing of tax returns and, in some instances, audited financial accounts are the compliance requirements. Non-compliance is enforced by penalties by the Tax Authority.

Corporate Income Tax Rates

Standard Rate: Resident and non-resident companies conducting commercial, industrial, or professional business in Oman have a uniform CT rate of 15%.

Petroleum Firms: Petroleum companies engaged in the selling of petroleum are liable to a flat tax rate of 55% as per specific Exploration and Production Sharing Agreements with the Omani government.

Small and Medium Enterprises (SMEs): Omani SMEs satisfying specific conditions are liable for a lower tax rate of 3%. Conditions include a registered capital of OMR 50,000 or less, gross income of OMR 100,000 or less, and the average number of employees in the tax year not exceeding 15.

Conclusion

The lack of taxes like payroll, capital gains, and inheritance taxes makes Oman an even more appealing place for business.

For compliance, companies are required to file their CT returns by the set deadlines, subject to penalty in case of non-filing or delay in payment. CIT registration and filing is an easy process using the Oman Tax Authority’s online platform, involving proper documentation and timely filing.

Companies must remain cautious about fulfilling tax requirements to escape penalties and ensure a hassle-free operation in Oman’s expanding economy. The simplified tax system, along with the absence of various prevalent taxes, makes Oman an attractive place for domestic and foreign enterprises alike.
