Most businesses in Oman only think about audits when something goes wrong a regulatory notice, a failed renewal, or a financial discrepancy that could have been caught months earlier.
The smarter approach? Build audit readiness into your operations before anyone comes knocking. Internal auditing has become one of the most essential functions for organizations in Oman. Beyond being a compliance requirement, internal audits serve as a strategic tool that helps businesses operate efficiently, manage risks, and maintain transparency.
Under the Oman Commercial Companies Law, businesses must maintain proper financial records and internal controls. And with regulators stepping up enforcement in 2025 including the Oman Tax Authority (OTA), Capital Market Authority (CMA), and Financial Services Authority (FSA) being audit-ready isn’t optional. It’s business-critical. This checklist gives your business a clear, practical framework to assess where you stand and what needs fixing before your next audit.
What Is an Internal Audit and Why Does It Matter in Oman?
An internal audit is an independent review of your business’s financial records, internal controls, operational processes, and compliance status. Unlike an external audit, it’s conducted proactively by your own team or an outsourced firm to catch issues before they become penalties.
The risks of skipping it are real: governance sanctions under Oman’s Corporate Governance Code, legal consequences for AML non-compliance, increased exposure to fraud and financial misstatements, and investor distrust that limits your access to capital and partnerships.
Done right, internal audits don’t just protect your business they strengthen it.
Internal Audit Checklist for Businesses in Oman
1. Financial Records and Reporting
This is the foundation of any internal audit. Before anything else, your financial records must be accurate, current, and IFRS-compliant.
- Are financial statements prepared in line with IFRS standards?
- Are all accounts reconciled bank, receivables, payables, inventory?
- Are revenue and expense entries properly classified and documented?
- Are related-party transactions disclosed accurately?
- Are financial records maintained for a minimum of 10 years as required?
Oman’s regulatory framework now mandates mandatory digital record-keeping and electronic submission so paper-only records are no longer sufficient.
2. Internal Controls Review
Weak internal controls are where fraud and financial errors enter. This section checks whether your control systems are actually working.
- Are authorization levels clearly defined for payments and approvals?
- Is there a proper segregation of duties no single person controls both recording and approving transactions?
- Are bank reconciliations reviewed and approved by a senior officer?
- Are petty cash controls and expense claim procedures documented and followed?
- Is there a process for identifying and reporting control failures?
Strong internal controls reduce the risk of fraud and errors and reflect positively in your audit report.
3. Regulatory and Tax Compliance
Oman’s compliance environment has grown significantly more rigorous. Your audit checklist must cover all active regulatory obligations.
- Is VAT registered, filed, and paid on time with the Oman Tax Authority (OTA)?
- Are corporate income tax returns filed correctly and on schedule?
- Is the business compliant with CMA regulations where applicable?
- Are AML/CFT policies documented, implemented, and reviewed periodically?
- Are all commercial licenses valid and renewed through MoCIIP?
Periodic compliance risk assessments, client due diligence, and independent compliance audits are now mandatory for relevant entities under Omani enforcement expectations.
4. Corporate Governance and Board Oversight
Governance failures are one of the most common audit findings and one of the most avoidable.
- Are board meetings held regularly with minutes formally documented?
- Is there an Audit Committee in place where required?
- Are conflict-of-interest policies documented and enforced?
- Are related-party transactions reviewed and approved at the board level?
- Does the business have a documented corporate governance policy?
The Muscat Stock Exchange (MSX) now requires mandatory ESG reporting for listed companies, making governance documentation a priority for 2025 and beyond.
5. HR and Payroll Compliance
People-related compliance is frequently overlooked and frequently flagged during audits.
- Are employee contracts current, signed, and on file?
- Is payroll processed accurately with proper deductions and records?
- Are PASI (Public Authority for Social Insurance) contributions up to date?
- Are Omanization quotas tracked and compliant with current requirements?
- Are HR policies leave, termination, grievance documented and consistently applied?
Non-compliance in payroll and labor regulations can result in penalties from the Ministry of Labour an area auditors are increasingly scrutinizing.
6. Procurement and Contract Management
Procurement is a high-risk area for irregularities, overpayments, and undisclosed relationships.
- Are purchase orders raised before commitments are made?
- Is there a formal vendor approval and due diligence process?
- Are contracts reviewed legally before signing?
- Are procurement decisions free from undisclosed conflicts of interest?
- Are goods and services received confirmed independently before payment is released?
A clean procurement trail is one of the clearest signals of a well-controlled business operation.
7. IT Systems and Data Security
As businesses in Oman accelerate digital operations, IT controls have moved from a technical concern to an audit priority.
- Are access rights to financial systems reviewed and restricted to authorized personnel?
- Is there a documented data backup and recovery procedure?
- Are system access logs maintained and reviewed regularly?
- Is cybersecurity policy documented and communicated to staff?
- Are software licenses valid and IT assets properly inventoried?
Mandatory digital record-keeping and enhanced focus on internal controls are now central to Oman’s evolving audit framework making IT controls a non-negotiable part of any checklist.
8. Fraud Risk Assessment
Fraud doesn’t always look dramatic. Often it’s small, systematic, and hidden in plain sight within weak processes.
- Is there a fraud risk register in place and reviewed annually?
- Are anonymous reporting channels (whistleblower policies) available to staff?
- Are unusual transactions or patterns flagged and investigated promptly?
- Is there a documented response plan if fraud is detected?
- Are high-risk roles subject to periodic rotation or dual-authorization controls?
Regular audits help detect irregularities early, reducing the risk of financial loss or data misuse. Prevention is always cheaper than investigation.
9. Asset Management
Unrecorded, misused, or missing assets are a red flag in any audit and surprisingly common in businesses without a proper asset management process.
- Is there a complete and current fixed asset register?
- Are physical assets verified against the register periodically?
- Are depreciation policies correctly applied and consistently followed?
- Are asset disposals documented with proper authorization?
- Are leased assets recorded and disclosed in financial statements?
10. Audit Documentation and Findings Management
An internal audit is only valuable if findings are properly recorded and acted upon. This final section checks your audit management process itself.
- Are previous audit findings tracked with corrective actions assigned and completed?
- Is there a formal audit report format used consistently?
- Are audit results presented to senior management or the board?
- Are high-risk findings escalated and resolved within defined timelines?
- Is the internal audit function reviewed for independence and objectivity?
Internal auditors are now expected to be proactive advisors, not just compliance checkers and your documentation should reflect that strategic role.
How Often Should Businesses in Oman Run Internal Audits?
The frequency depends on your business size, industry, and risk profile but as a general guide:
- High-risk sectors (financial services, construction, healthcare): Quarterly or continuous auditing
- Mid-sized businesses: Semi-annual internal reviews
- SMEs: Annual internal audit as a minimum
For small and medium businesses, an internal audit typically takes four to six weeks. For large corporations, it usually takes six to eight weeks. Planning ahead prevents bottlenecks during peak compliance periods.
Common Internal Audit Failures in Oman Businesses
Even well-intentioned businesses make avoidable mistakes. The most common ones include:
- Treating internal audit as a once-a-year box-tick rather than an ongoing process
- Having no follow-up system for previous audit findings
- Mixing audit and operational responsibilities within the same team killing independence
- Ignoring IT controls entirely until a breach occurs
- Keeping paper-only records in an environment shifting to mandatory digital submission
Catching these early is far less costly than discovering them during an external audit or regulatory inspection.
