About Tax Rights in Oman
You pay no personal income tax in Oman. Businesses face 15% corporate income tax on profits under the Income Tax Law (Royal Decree 28/2009), with a small business exemption under OMR 30,000. 5% VAT applies to most goods and services under Royal Decree 121/2020 — you must register if turnover exceeds OMR 38,500. The Tax Authority of Oman runs everything. Withholding tax of 10% applies to non-resident royalties and management fees. Free zones (Duqm, Sohar, Salalah, Al Mazunah) get tax holidays. Object to assessments within 45 days, then appeal to the Tax Committee.
