Frequently Asked Questions

Got any questions? We got you covered

A financial statement audit is an independent examination of your company's financial statements to ensure accuracy, compliance with accounting standards (IFRS) and adherence to Omani legal requirements. Many entities in Oman — including LLCs above certain thresholds and companies bidding for tenders or seeking bank financing — need audited financial statements every year.

Internal and management audits evaluate your internal controls, risk management processes and operational efficiency. They uncover leakages, strengthen governance and give owners and boards genuine visibility into how the business is running — before problems become expensive.

Yes. We handle the complete VAT lifecycle in Oman — registration with the Oman Tax Authority, transaction mapping, quarterly return filing, compliance reviews and representation during tax audits.

Absolutely. Our Corporate Services team manages company formation end-to-end: legal structure advice, commercial registration, licensing, PRO services and guidance on Oman's 100% foreign ownership rules under the Foreign Capital Investment Law.

A business valuation determines the fair value of a company using recognised methodologies. You'll typically need one when buying or selling a business, bringing in investors, resolving shareholder matters or planning a restructuring.
