Article 159 bis 15 establishes the preferential tax rate for eligible enterprises at 3% of their taxable income. This significantly lower rate (compared to the standard 15%) is designed to foster small business growth in Oman. However, the Article provides two major exemptions: (1) enterprises managed on a full-time basis by their owners or partners, and (2) enterprises that employ at least two Omani persons are excluded from this 3% tax (often effectively resulting in a 0% rate for such compliant micro-entities). This encourages Omani entrepreneurship and local employment in the SME sector.
