A control can look perfect on paper and still fail when a real transaction passes through it. That is where Internal Audit Saudi Arabia becomes important for companies dealing with financial, operational, technology, compliance and governance risks. A strong internal audit function does more than identify errors after they happen. It checks whether controls work in practice, whether risks are being addressed and whether management is taking action on reported findings.
For Saudi businesses, the approach also needs to reflect applicable SAMA, CMA and other regulatory requirements, along with the current IIA Global Internal Audit Standards. Our Internal Audit Services KSA help businesses assess their internal audit processes, identify control weaknesses and review areas that may expose the company to financial or Audit Compliance risks. This guide explains practical internal audit best practices for Saudi companies.
What Are Internal Audit Best Practices for Saudi Businesses?
For Saudi companies, good internal audit starts with independence, risk-based planning and reliable evidence. It should also cover the controls, risks and regulatory obligations that matter to the specific business.
- Maintain internal audit independence and objectivity.
- Build the audit plan around current business risks.
- Keep the internal audit charter clear and current.
- Test controls instead of checking policies only.
- Review financial, operational, IT and compliance risks.
- Match audit work with applicable Saudi regulatory requirements.
- Follow the current IIA Global Internal Audit Standards.
- Keep sufficient evidence for every audit conclusion.
- Write reports that clearly explain risks and required action.
- Track corrective actions and retest important findings.
Internal Audit Best Practices Explained
1. Maintain Internal Audit Independence and Objectivity
An internal audit team cannot give an unbiased view if it is responsible for the activities it later reviews. Independence allows auditors to report weaknesses without pressure from the department being audited.
- Keep the internal audit function separate from operational management.
- Give the head of internal audit direct access to the Audit Committee.
- Do not assign auditors responsibility for designing or running the controls they audit.
SAMA’s principles for local banks require internal audit to remain independent from business units and the first and second lines of defence, with direct communication with the Audit Committee.
2. Why Independence Matters According to the Audit Committee
The Audit Committee needs reliable information about control weaknesses, compliance issues and unresolved findings. It should be able to discuss audit results with internal auditors without management changing or filtering the findings.
- Review the internal audit plan and its risk basis.
- Discuss significant findings and overdue actions.
- Assess whether the internal audit function has enough authority and resources.
For SAMA-regulated banks, the Audit Committee reviews and approves the annual audit plan, discusses reports and monitors corrective action taken by management.
3. Build a Risk-Based Internal Audit Plan
An audit plan should reflect where the business faces the greatest risk, not simply repeat the same audits every year. This supports effective Risk Management KSA across the company.
- List major business units, processes, systems, subsidiaries and third-party activities.
- Rank risks using factors such as financial impact, regulatory exposure, control weaknesses and recent changes.
- Give higher-risk areas more frequent or detailed audit coverage.
SAMA’s banking principles require the annual internal audit plan to be based on a risk assessment and reviewed when the bank’s risk profile changes. A risk-based approach also helps Saudi businesses direct limited audit resources towards areas that could cause the greatest financial, operational or regulatory impact.
4. Keep the Internal Audit Charter Clear and Current
An internal audit charter sets out what the audit function can do, who it reports to and how it works with management and the Audit Committee. It should reflect the company’s current structure rather than remain an old document that nobody reviews.
The charter should state the audit function’s purpose, authority, scope, reporting arrangements, access to records, responsibilities and relationship with the Audit Committee. It should also explain the limits of advisory work so that audit independence is not affected. For regulated entities, the charter and internal audit policy should also reflect applicable regulatory expectations. Reviewing the charter periodically helps the business identify changes in reporting lines, business activities, systems and regulatory obligations.
5. Test Internal Controls, Not Just Policies
A written policy does not prove that a control works. Internal Controls Saudi Arabia businesses rely on need to be checked against actual transactions, approvals, system records and supporting evidence.
- Test whether purchase and payment approvals follow authorised limits.
- Review segregation of duties for sensitive activities such as vendor creation and payments.
- Check whether access rights, reconciliations and management reviews are performed as required.
The purpose is to identify the difference between what the company says should happen and what actually happens during day-to-day operations.
6. Cover Financial, Operational, IT and Compliance Risks
Internal audit should not focus only on accounting records. A Saudi company may face significant risks through technology, suppliers, customer data, operations and regulatory obligations.
- Financial: Review payments, reconciliations, journal entries, revenue and asset controls.
- Operational: Check approvals, process delays, service quality and segregation of duties.
- IT and compliance: Review user access, system changes, cybersecurity controls, regulatory obligations and internal policies.
The exact audit scope should depend on the company’s activities and risk profile rather than using the same audit programme for every Saudi business.
7. Align Internal Audit Saudi Arabia Work With Regulatory Requirements
Saudi businesses do not all follow the same regulatory framework, so Audit Compliance requirements can differ for a listed company, bank, finance company or private non-regulated business.
- SAMA: Relevant banks and financial institutions need to consider SAMA’s internal audit and governance requirements.
- CMA: Companies subject to CMA rules need to follow the applicable Corporate Governance Regulations and internal control requirements.
- Other requirements: Companies should also consider applicable NCA, PDPL, labour, tax, sector and contractual requirements when these affect their operations.
CMA requirements for covered companies include internal control arrangements and an internal audit function responsible for assessing controls and compliance.
The Saudi Authority of Internal Auditors, known as SAIA, is now the professional authority for internal auditing in the Kingdom. Its name changed from the Saudi Institute of Internal Auditors in April 2025, alongside changes to its professional role.
8. Follow the Current IIA Global Internal Audit Standards
In 2026, Saudi businesses should refer to the current IIA Global Internal Audit Standards rather than relying on the previous framework. The current Standards became effective on 9 January 2025 and form part of the 2024 International Professional Practices Framework.
- Align internal audit governance with the current professional requirements.
- Build risk-based planning, communication and performance measurement into the audit function.
- Keep evidence showing how the internal audit function meets applicable requirements.
The current Standards place attention on governance, stakeholder relationships, internal audit strategy, performance and accountability. These areas can help Saudi businesses assess the overall quality of their internal audit function.
9. Use Strong Audit Evidence and Documentation
An audit conclusion should be supported by records that another qualified reviewer can understand. Good documentation also makes follow-up easier when management challenges a finding.
- Record the audit objective, scope, risks and procedures performed.
- Keep samples, reports, system records and other supporting evidence.
- Document findings, management responses, responsible owners and agreed deadlines.
The audit file should show how the auditor moved from the identified risk to the testing performed and then to the final conclusion.
10. Write Clear Internal Audit Reports
A useful audit report should tell management what went wrong, why it matters and what needs to happen next. Long descriptions without a clear risk or action can make important findings harder to address.
- State the condition or control weakness clearly.
- Explain the risk and likely cause.
- Record the recommendation, responsible owner and target completion date.
For regulated entities, reporting can also involve formal periodic reports to the Audit Committee and Board. These reports may cover control assessments, significant findings, recommendations and the status of previous findings.
11. Track Corrective Actions and Retest Findings
An audit does not finish when the report is issued. The business needs to show that agreed corrective actions were completed and that the original weakness has actually been addressed.
- Maintain a record of open findings, owners, deadlines and current status.
- Escalate overdue high-risk findings to the appropriate management level or Audit Committee.
- Retest significant corrective actions before marking important findings as closed.
SAMA requirements for applicable banks place responsibility on management to take timely corrective action on internal audit findings, while the Audit Committee monitors the progress of those actions.
12. Include Fraud, Cybersecurity and Third-Party Risk
Some of the most serious control problems may sit outside traditional financial auditing. Internal audit should consider how fraud, technology and outsourced services could affect the company.
- Fraud: Review vendor creation, unusual payments, conflicts of interest and management override controls.
- Cybersecurity: Test access rights, privileged accounts, system changes, backups and incident controls.
- Third parties: Review vendor due diligence, contracts, data access, service performance and outsourced processes.
Saudi businesses that rely heavily on digital systems and external service providers should give these areas suitable attention within their Risk Management KSA assessment and annual audit plan.
13. Measure Internal Audit Performance
Internal audit should be measured by the quality and usefulness of its work, not only by the number of audits completed.
- Track completion of the approved audit plan and coverage of high-risk areas.
- Monitor overdue and repeat findings and the time taken to close important actions.
- Review stakeholder feedback, quality assessment results and the value of audit recommendations.
These measures help the Audit Committee see whether internal audit resources are being used properly and where the function may need additional skills or resources.
14. Maintain Quality Assurance and Improvement Progress
A good internal audit function should regularly review its own work. This helps identify weaknesses in audit planning, documentation, reporting, staff capability and follow-up.
- Perform ongoing monitoring and internal quality reviews.
- Record improvement actions and check whether they have been completed.
- Arrange external quality assessment where required or appropriate.
The current IIA Standards include requirements around quality assurance and improvement. For applicable banks, SAMA’s principles also provide for independent external assessment of internal audit quality at least once every five years.
