Statutory Audits (ISA-Compliant)
Prepare for mandatory annual financial statement audits required under the Omani Commercial Companies Law for LLCs, SAOCs, and SAOGs. We assemble IFRS-compliant accounts, ISA-indexed working papers, and PBC schedules so your MOCIIP-licensed external auditor can issue an unmodified opinion and you meet commercial registration renewal, CMA disclosure, and OTA tax filing deadlines.

Under the Omani Commercial Companies Law, SAOGs (public shareholding companies) and SAOCs (closed shareholding companies) must appoint a MOCIIP-licensed auditor and prepare annual audited financial statements under IFRS, applying International Standards on Auditing (ISA). LLCs exceeding prescribed capital or revenue thresholds, foreign branch offices, and companies with bank loan covenants or government contract requirements also face mandatory audit obligations. CMA-listed SAOGs on the Muscat Stock Exchange (MSX) face additional audit and disclosure requirements under Capital Market Authority regulations. Companies subject to OTA corporate income tax must submit audited accounts with tax returns above prescribed thresholds. We prepare audit-ready working papers including adjusted trial balances, bank reconciliations, revenue cut-off testing schedules, and related-party disclosures before your MOCIIP-licensed external auditor begins fieldwork — reducing billable hours, accelerating report issuance ahead of MOCIIP renewal deadlines, and minimising repeat findings across multi-entity Oman portfolios.

Internal Audit & Management Review
Evaluate internal controls, operational processes, and financial reporting workflows through structured internal audit and management review programmes for Omani entities. Internal audit identifies control weaknesses before your external auditor, MOCIIP regulator, CMA reviewer, or the OTA does — reducing fraud risk, qualified opinions, and compliance penalties across mainland and government-contracting operations.

Internal audit and management review services evaluate whether your Omani organisation's controls over financial reporting, OTA tax compliance, and operations are designed and operating effectively. We apply COSO principles and the Three Lines Model referenced by ISA 315 when external auditors assess control environments during Oman statutory audits. Our engagements cover entity-level controls, IFRS 15 revenue recognition walkthroughs, OTA VAT input and output tax controls, PASI payroll processing, procurement and disbursement cycles, and IT general controls across LLC, SAOC, and SAOG entities. Findings are classified by severity with remediation plans — the same discipline external auditors apply when evaluating deficiencies during MOCIIP-licensed audit and CMA regulatory fieldwork. Remediation before your statutory audit reduces qualified opinion risk and repeat findings that increase audit costs annually, particularly for CMA-listed SAOGs subject to enhanced governance expectations and government contractors subject to OAB oversight requirements.

The Oman Tax Authority administers corporate income tax at 15% under Royal Decree 53/2019, VAT at 5%, withholding tax on cross-border payments, and excise tax on specified goods. The OTA Tax Procedures Law empowers the authority to conduct tax audits covering up to five years of returns, requesting reconciliations between IFRS accounting records, audited financial statements, corporate tax submissions, VAT returns, and supporting documentation for transfer pricing and related-party transactions. Companies must maintain accounting and tax records for ten years under OTA requirements. We prepare comprehensive audit response packages including book-to-tax reconciliations, VAT invoice registers with input and output tax schedules, withholding tax remittance certificates, related-party transaction schedules, and fixed asset tax depreciation schedules. Proactive preparation reduces OTA assessment adjustments, penalty exposure, and interest on unpaid tax liabilities identified during the five-year audit review period.

Certifier audit coordination

In-Country Value (ICV) certification measures the contribution of Omani goods, services, and employment to the local economy — a requirement increasingly mandated by Petroleum Development Oman, OAB government entities, and major corporate tender programmes for supplier eligibility and contract award scoring. ICV certifiers conduct audits verifying that claimed local expenditures — including Omani payroll, local procurement, and domestic subcontractor payments — are accurately recorded and supported by documentary evidence reconcilable to audited IFRS financial statements. We prepare ICV expenditure registers categorised per certifier methodology, reconcile qualifying spend to general ledger and trial balance figures, and coordinate documentation timing with your MOCIIP-licensed statutory audit so ICV schedules and audited accounts present consistent revenue and expenditure figures. Proper ICV audit support improves certification scores, protects government contract eligibility, and reduces certifier audit findings that delay tender submissions.

Inventory and fixed assets represent high-risk audit areas for Omani trading, manufacturing, logistics, and construction entities subject to mandatory IFRS audits under the Commercial Companies Law, OTA tax filing requirements, or CMA regulatory mandates for listed SAOGs. External auditors apply ISA 501 and ISA 540 substantive procedures including physical observation of inventory counts, fixed asset existence verification, and depreciation recalculation under IAS 16 and IAS 2. We plan and execute stocktake procedures, coordinate auditor attendance at year-end counts, verify asset existence against registers, and reconcile carrying values to IFRS-compliant depreciation schedules. Proper verification reduces audit scope limitations, accelerates fieldwork for Oman warehouse and retail operations, and ensures asset values support accurate OTA corporate tax computations and balance sheet presentation for MOCIIP-licensed statutory audits.

Special-purpose audits address targeted assurance needs beyond MOCIIP-licensed statutory audit scope — including agreed-upon procedures under ISA 4400 for Omani bank lending covenants, quality of earnings analyses for M&A transactions, and project cost certification for government and infrastructure contracts with OAB entities. Oman banks routinely require AUP reports on working capital, revenue verification, or net debt calculations as conditions for facility agreements. Investors acquiring LLC, SAOC, or SAOG targets request normalised EBITDA schedules adjusting for non-recurring items, related-party transactions, and OTA tax contingencies. CMA-listed SAOG transactions may require additional disclosure-aligned special-purpose procedures. We scope each engagement to your specific requirements, coordinating with MOCIIP-licensed auditors where joint reporting is needed for group structures and government contractor compliance programmes.

Omani banks, sovereign wealth co-investors, and international private equity firms routinely require audited or reviewed IFRS financial statements as conditions for lending, investment, or acquisition transactions. Oman-based lenders typically mandate debt service coverage and leverage covenant testing on audited accounts, while investors request quality of earnings analyses and agreed-upon procedures under ISA 4400 on revenue, working capital, and related-party balances. We prepare transaction-ready financial packages including normalised EBITDA schedules, covenant compliance calculations, and indexed data room documentation for due diligence. Whether supporting a MOCIIP trading company refinancing, a SAOC holding structure investment, or a CMA-listed SAOG acquisition, our preparation accelerates MOCIIP-licensed external auditor fieldwork and reduces transaction timeline risk from incomplete financial records.

Coordinating with your MOCIIP-licensed external auditor is critical to completing Oman statutory audits on time and within budget. External audit firms bill primarily for fieldwork time spent resolving incomplete PBC requests and testing exceptions. We manage the full auditor relationship: reviewing engagement letters for appropriate scope, fulfilling PBC lists with indexed trial balances and reconciliations, responding to fieldwork queries during ISA audit programmes, and coordinating report issuance for MOCIIP commercial registration renewal and CMA disclosure filing for listed SAOGs. Our liaison ensures consistent figures across statutory audit working papers, OTA corporate tax and VAT reconciliations, ICV expenditure schedules, and PASI contribution registers — reducing repeat inquiries and protecting audit timelines for CMA-listed disclosure and lender covenant certification.

Audit readiness assessment is the most effective way to control external audit costs and meet Oman regulatory filing deadlines — whether for Commercial Companies Law MOCIIP statutory audits, CMA-listed SAOG reporting, ICV certifier substantiation requiring audited accounts, or OTA tax return filing under the Tax Procedures Law. We assess your records against ISA PBC expectations and IFRS disclosure requirements before your MOCIIP-licensed auditor begins fieldwork, identifying unreconciled accounts, missing related-party schedules, inadequate going-concern documentation, and OTA tax reconciliation gaps. Remediating issues pre-audit reduces billable hours, prevents scope limitations that delay report issuance, and ensures consistent figures across your statutory audit, ICV certification, and OTA corporate tax and VAT returns — protecting commercial registration renewal timelines and CMA disclosure obligations for listed SAOGs.
