Oman's tax landscape has moved quickly Income Tax Law compliance for companies, a 5% VAT regime in force since 2021, transfer pricing documentation expectations under OECD-aligned rules, and a phased e-invoicing mandate on the horizon. For businesses operating in the Sultanate, getting tax right is no longer optional; penalties, reputational damage and blocked tenders follow from getting it wrong.

Companies operating in Oman are generally subject to corporate income tax under the Income Tax Law, with rates and exemptions varying by entity type, sector and free zone status. SMEs below certain thresholds may qualify for reduced rates, which a tax advisor can help you confirm.
Oman applies a standard VAT rate of 5%. Businesses whose taxable supplies exceed the mandatory registration threshold must register with the Oman Tax Authority, while businesses below that threshold may register voluntarily. Certain supplies are zero-rated or exempt, so classification matters.
Oman is rolling out e-invoicing in phases as part of its digital tax administration programme. Businesses should begin readiness assessments early, since system and process changes typically take longer than expected. We can help confirm the current phase timelines and thresholds relevant to your business.
Companies with related-party transactions above the thresholds set by the Oman Tax Authority are generally expected to maintain transfer pricing documentation demonstrating arm's-length pricing. This typically applies to multinational groups and larger local groups with cross-border or related-party dealings.
