Article 68 defines key terms for the loss carry-forward regime in Oman. 'Exemption Period' refers to any duration where a company is legally exempt from tax. 'Exemption under Article 118' specifies a particular statutory relief. 'Net Loss' is defined as the total loss incurred during the first five years of an Article 118 exemption period, minus any exempted income from those same years. Both losses and exempted income must be computed using the standard taxable income rules. These definitions provide the framework for how tax-exempt entities transition into the standard tax regime while utilizing historical losses.
