  • Replacement of the process of filing both provisional and final income tax returns with the process of filing a single income tax return within 4 months from the end of the accounting period.
  • Introduced a new concept of tax residency rule: a natural person will be a resident if he or she spends 183 days or more (consecutive or intermittent) in Oman during the tax year and a legal person will be a tax resident if it has been established in accordance with the laws and Royal Decrees in force in Oman, or if its headquarters or head office is in Oman. Amendments regarding residence are effective 21 September 2020.
