New Income Tax Rules For Business Expenses From 2027
Before the issuance of Tax Authority Decision No. 180/2026, the deductibility of business expenses in Oman was governed by the general rules set out in Article 18 of the Executive Regulations of the Income Tax Law. Among other things, those rules require that an expense be genuine, relate to the taxpayer's business, be necessary to generate income, and be supported by appropriate documentation.
