Hiring an audit firm without the correct professional licence puts your company’s financial reporting and compliance arrangements at risk. In Oman, a Commercial Registration (CR) alone does not authorise a firm to provide accounting and auditing services. The Financial Services Authority (FSA) regulates the profession, and businesses need to verify an audit firm’s authorisation before signing an engagement or submitting financial records.
The audit firm licensing Oman framework has received increased regulatory attention in 2026, with the FSA taking action against unlicensed practice, incomplete registration and breaches of professional requirements.
These developments matter to companies appointing external auditors, existing audit practices renewing their licences and businesses checking whether their appointed firm is authorised to carry out the required work.
What Is the FSA’s Role in Audit Firm Licensing in Oman?
Oman’s Financial Services Authority regulates the accounting and auditing profession under the framework established by Royal Decree No. 20/2024, which transferred responsibility for regulating and licensing the profession from the Ministry of Commerce, Industry and Investment Promotion (MOCIIP) to the FSA.
The profession remains governed by the Accounting and Auditing Profession Law issued under Royal Decree No. 77/86, alongside applicable decisions, regulations and professional standards.
The FSA’s responsibilities include licensing accounting and auditing practices, maintaining professional registers, monitoring compliance and taking action against violations. Its oversight covers the authorisation of firms and the professional conduct of those carrying out audit work.
Why the Licensing Framework Matters in 2026
The FSA’s regulatory activity during 2026 has reinforced the need to verify authorisation rather than rely on a company’s commercial documents.
Key developments include:
- February 2026: The FSA warned businesses to verify accounting firms’ authorisation and stated that a commercial registration does not grant permission to practise accounting and auditing without the required professional licence.
- June 2026: The FSA directed applicants with previously submitted registration and licensing applications to complete their procedures and provide the necessary documents within a specified 30-day period beginning on 2 June 2026. The circular stated that earlier procedures or approvals would be invalid for applicants who failed to complete the required steps within that period.
- July 2026: The FSA announced enforcement action against an audit firm over violations involving unlicensed practice, audit-report signatures, professional experience and licence renewal.
- October 2026: The FSA warned firms against assigning audit and account examination work to individuals who were not registered employees of the firm.
Requirements of Audit Firm Licensing in Oman
An accounting or auditing practice needs the appropriate FSA authorisation before providing regulated professional services. The application route and supporting documents depend on the type of licence or approval being requested.
Businesses establishing an audit practice need to distinguish between the requirements for registering a commercial entity and those for obtaining professional permission to practise.
1. Commercial Registration
The applicant needs the relevant commercial registration documentation for the business. This establishes the company’s registered identity and business details.
However, a CR does not replace the FSA’s professional licence. A business that has completed its commercial registration still needs the applicable authorisation before providing accounting and auditing services.
2. Professional and Academic Qualifications
The FSA’s licensing procedures include requirements relating to professional competence and academic qualifications. The exact requirements depend on the application category and the applicant’s role.
Applicants should prepare the qualifications, academic records and experience certificates specified for their application. Where the procedure requires evidence of practical accounting or auditing experience, the submitted records need to demonstrate that experience.
3. Practical Experience
Relevant professional experience forms part of the requirements for certain licensing and auditor-approval applications.
Applicants need to review the conditions applicable to their category rather than assume that an accounting qualification alone establishes eligibility. The type and duration of experience, supporting certificates and other professional conditions depend on the relevant FSA procedure.
4. Ownership and Management Information
The application can require information about the firm’s owners, partners, managers and other responsible individuals. Where foreign partners or managers are involved, additional documents can apply.
The government service for a new accounting and auditing office licence lists documents such as foreign office certification for a foreign partner, residence card details for foreign managers, experience certificates and identification documents.
5. Professional Staffing and Supervision
A licensed firm must ensure that people performing regulated audit work meet the applicable registration and professional requirements.
The FSA’s October 2026 warning specifically addressed cases where licensed firms assigned audit or account examination work to individuals who were not registered employees of the firm.
Firm owners remain responsible for work carried out under their firm’s name and authority. They need to maintain appropriate supervision, check staff status, and ensure that professional assignments comply with the applicable rules.
How to Complete Oman Audit Firm Registration
The application process depends on whether the applicant is establishing a new accounting and auditing practice, renewing an existing licence or seeking a separate approval for an auditor or audit firm.
The following steps outline the main stages for a new practice.
Step 1: Identify the Correct FSA Application
Start by confirming the professional licence or approval required for the proposed services. The FSA and the official Gov.om portal provide specific services for licensing accounting and auditing offices and obtaining approval for auditors.
Choosing the correct application matters because a licence for practising the profession and an approval to audit particular categories of companies are not necessarily the same authorisation.
Step 2: Prepare the Required Documents
Review the official checklist and prepare the documents for the relevant application. Depending on the route, the requirements can include:
- Commercial Registration certificate
- Academic qualifications and approved subject details
- Professional experience certificates
- Passport, identity or residence documents
- Information about partners, managers and authorised signatories
- Foreign-partner documentation, where applicable
- Professional association membership evidence, where required
- Any declarations or supporting records requested by the FSA
Step 3: Submit the Application Electronically
The FSA launched an electronic licensing system in July 2025 for new applications and licence renewals. The system allows applicants to upload documents and track the progress of their applications.
Submit the application through the designated electronic channel and retain the application reference for follow-up.
Step 4: Complete the Initial Approval Stage
Where the selected licensing procedure includes initial approval, the FSA reviews the application and supporting documents before the applicant proceeds to the next stage.
Follow any instructions issued during the review and provide additional information when requested. Initial approval does not automatically mean that the final professional licence has been issued.
Step 5: Complete Final Approval and Payment
After meeting the applicable conditions, complete the final approval procedure and pay the prescribed fees.
The FSA reviews the application before issuing the relevant licence or approval. Applicants need to confirm that the authorisation has been issued before commencing regulated professional work.
Step 6: Maintain the Licence After Approval
Once licensed, the firm needs to comply with the conditions attached to its authorisation, including renewal requirements, staff registration, professional standards and audit-reporting obligations.
Keep a record of renewal dates, changes in ownership or management, staff details and any additional approvals required for the firm’s work.
What Is the Difference Between an FSA Licence and Auditor Approval?
Businesses appointing an audit firm need to check that its authorisation covers the work they intend to commission. The existence of a professional licence does not automatically establish that every separate approval requirement has been met.
| Authorisation or document | Purpose |
| Commercial Registration | Establishes the business’s registered commercial identity. |
| FSA licence to practise | Authorises the accounting or auditing practice to provide the relevant professional services. |
| Auditor approval | Covers the relevant approval process for an individual auditor, where applicable. |
| FSA accreditation for particular audit work | May be required for auditing companies subject to additional regulatory requirements, depending on the applicable rules. |
Licence Renewal and Ongoing Compliance
Obtaining an FSA licence is only the first part of running an authorised audit practice. Firms must keep their registration current and comply with the applicable professional and administrative requirements throughout their operations.
Track Renewal Deadlines
The FSA has taken enforcement action against firms that failed to submit licence renewal applications within the prescribed period. Maintain a renewal calendar and check the current submission requirements before the licence expires.
Do not assume that an earlier commercial registration or previous approval automatically extends the validity of a professional licence.
Keep Staff Registration Up to Date
The firm needs to review the status of employees assigned to accounting and auditing work. Check that the relevant individuals are properly registered and that assignments comply with the professional requirements.
The October 2026 FSA warning makes this an immediate compliance priority. Firms must not assign regulated audit work to unregistered individuals from outside their registered staff.
Maintain Audit Files and Working Papers
The FSA has reiterated the requirement for audit firms to retain audit files and working papers for ten years under the applicable law.
These records support the audit work performed, document the evidence reviewed and provide a basis for regulatory inspection. Firms need a consistent system for preparing, storing and retrieving engagement records throughout the required retention period.
Ensure Audit Reports Meet Professional Standards
Audit reports must comply with the applicable legal requirements and professional standards, including relevant International Standards on Auditing (ISAs).
The FSA’s 2026 supervisory updates have highlighted deficiencies involving audit evidence, engagement letters, audit documentation, materiality, related-party transactions and report structure. Firms need appropriate procedures to address these areas and ensure that audit conclusions are supported by sufficient evidence.
Ensure Proper Signature and Accountability
The FSA has highlighted the requirement for the owner of an audit firm to personally sign audit reports under the applicable provisions of the Accounting and Auditing Profession Law.
Firm owners must review the requirements that apply to their practice and ensure reports are issued and signed in accordance with the law. Delegating audit work does not remove the firm’s responsibility for the quality and compliance of work performed under its authority.
How Businesses Can Verify Licensed Audit Firms in Oman
Before appointing an external auditor, businesses need to confirm that the firm is authorised to provide the required services. This check is especially important when a potential provider presents a CR, company profile or professional credentials as evidence of its status.
Use the following steps to verify a firm:
- Check the FSA’s official register: Visit the FSA website at fsa.gov.om and access the relevant list of authorised accounting and auditing offices.
- Confirm the firm’s identity: Compare the listed name with the name on its commercial documents, proposal and engagement letter.
- Review its authorisation: Confirm that the firm appears under the appropriate licensed category and that the available record supports the services it proposes to provide.
- Check additional approvals: If your company falls under a regulated sector, establish whether the audit appointment requires separate accreditation or approval.
- Confirm the engagement details: Review the scope of work, responsible auditor, reporting arrangements, and professional obligations before signing the agreement.
What Happens If an Audit Firm Operates Without an FSA Licence?
Operating without the required professional licence exposes an audit practice to regulatory action. The FSA has identified unlicensed accounting and auditing activity and has taken action against firms for breaches of the law.
Consequences depend on the violation and the applicable legal provisions. They can include regulatory warnings, suspension, deregistration, penalties or other enforcement measures.
Businesses also face risks when they appoint an unauthorised provider. These include disputes over the validity of the engagement, delays in obtaining acceptable audit reports and the need to appoint another firm to complete the work.
Common Mistakes in Oman Audit Firm Registration and Licensing
Applicants and existing firms can avoid unnecessary regulatory problems by addressing common weaknesses early.
Treating a CR as a professional licence: Commercial registration and professional authorisation serve different purposes. Complete the required FSA licensing process before offering regulated services.
Using outdated approval records: Previous approvals do not automatically establish current authorisation. Check the firm’s present status and comply with the applicable renewal requirements.
Submitting incomplete documentation: Missing qualifications, experience certificates or partner details can delay the application. Use the current official checklist for the relevant licensing category.
Assigning work to unregistered personnel: Firms need to confirm staff registration and ensure that regulated audit work is performed by eligible personnel under appropriate supervision.
Neglecting audit documentation: Incomplete working papers, insufficient evidence and missing engagement letters can lead to regulatory findings. Maintain records that demonstrate how audit procedures were performed and how conclusions were reached.
Overlooking additional accreditation: A general licence does not necessarily cover every type of regulated audit engagement. Confirm whether the client or sector requires a separate approval.
Verify FSA Licensing Before Appointing an Audit Firm in Oman
Oman’s audit firm licensing requirements place clear responsibility on accounting and auditing practices to hold the correct professional authorisation, maintain registered staff and comply with applicable audit standards. The FSA’s enforcement activity in 2026 makes verification an essential step for both businesses appointing auditors and firms providing professional services.
Check the official register, confirm the firm’s licence and identify any additional approval required for your engagement before signing a contract. Audit firms also need to monitor renewals, maintain audit files and ensure that all professional work is performed by eligible personnel under proper supervision.

7. Do all audit firms need additional FSA accreditation?
Not every engagement requires the same approval. Firms need to check whether the type of client or regulated activity requires additional accreditation beyond the general licence to practise accounting and auditing.
