Oman's Secretariat General for Taxation has issued an announcement that effective 1 November 2018, the submission of the statement of remittance of withholding tax must be made electronically through the tax portal of the Secretariat and that hard copies will no longer be accepted from that date. Oman generally levies a 10% withholding tax on dividends, interest, royalties, and service fees paid to non-residents, unless an applicable tax treaty provides otherwise.
