The main private company structure in Oman is the limited liability company (LLC), formed under the Commercial Companies Law and registered with the Ministry of Commerce, Industry and Investment Promotion (MOCIIP) through its Invest Easy platform. The LLC is the most frequently used entity because of its speed of establishment, limited liability and relaxed capital rules, and most commercial activities allow 100 percent foreign ownership.

Compliance involves MOCIIP for commercial registration, the Oman Tax Authority (OTA) for corporate income tax, VAT and withholding, the Public Authority for Social Insurance (PASI), the Ministry of Labour for work permits and Omanisation, municipalities, and sector regulators. Oman has moved quickly to digitise tax administration, and corporate tax registration is now a standard requirement for all commercial registration holders.

This guide explains the annual cycle for an LLC, with attention to foreign-owned subsidiaries. Updated November 9, 2026. Oman is rolling out new tax requirements including e-invoicing and transfer pricing rules, and service provider guides differ on some deadlines, so confirm specific dates with the OTA, MOCIIP or a licensed Omani auditor.

Entity compliance Oman: the quick answer

• Renew the commercial registration and licences each year, and keep the Chamber of Commerce membership active.

• Register with the OTA for corporate income tax within 60 days of establishment or commencement, and file an annual tax return even when there is a loss or an exemption.

• Prepare audited financial statements and file the annual return, which most sources place at four months after year-end, although one provider describes six months, so confirm the OTA's current period.

• Register for VAT above the threshold, file quarterly returns, and meet Omanisation and social insurance duties.

What determines a company's compliance requirements?

Sector, ownership and activity determine the workload. Some activities need sector licences or higher capital, and a foreign-owned LLC in certain commercial activities may be required to meet a minimum paid-up capital for the licence. Companies in free zones and special economic zones follow the rules of the zone authority, with special tax treatment in some cases.

Tax status also matters. The standard corporate income tax rate is 15 percent, with a reduced rate for small companies in some cases, and oil and gas companies are taxed under separate rules. The financial year is generally the calendar year, but it can differ if approved, and the OTA expects the year to be consistent with the commercial records.

Annual entity requirements in Oman: the core checklist

1. Commercial registration and licence renewal

The commercial registration is renewed annually with MOCIIP, and related licences, municipality approvals, lease agreements and Chamber of Commerce memberships are renewed alongside it. A company with foreign employees must also keep a local Public Relations Officer for government dealings. Failure to renew can block services and visa processing.

2. Audited financial statements

LLCs prepare financial statements under IFRS and have them audited by a licensed Omani auditor. Audited statements are required for the tax return, and failure to submit them leads to an incomplete return and potentially an estimated profit assessment. Banks and the parent group also expect them for renewals and funding.

3. Annual corporate tax return

The tax return is filed through the OTA's electronic portal. Several sources describe a four month period after year-end, which means 30 April for a calendar year, while a service provider states six months, so confirm the due date. Late filing can lead to fines between OMR 100 and OMR 2,000 and to an estimated assessment by the OTA. Companies with a loss or exemption must still file.

4. VAT returns

Oman introduced VAT at 5 percent in April 2021. Businesses with annual supplies above OMR 38,500 must register, with a lower voluntary threshold for some businesses. Returns are filed quarterly, with the tax payable at the same time, and some taxpayers file monthly. Late registration or filing can lead to administrative fines.

5. Registers and amendments

Maintain the register of partners, articles, resolutions and the commercial register file. Changes to partners, managers, capital, address and activities are registered with MOCIIP, often with notarised and legalised documents for foreign partners. Keep the commercial registration, tax card and municipality licences consistent.

Tax and indirect tax obligations

Corporate income tax of 15 percent applies to resident and non-resident companies on Omani-sourced income, and the OTA has indicated that the tax base includes certain overseas income for Omani companies. A reduced 3 percent rate is available for qualifying small taxpayers, subject to conditions. Withholding tax of 10 percent applies to payments such as royalties, management fees, consulting fees and research and development payments to non-residents, and 10 percent on dividends and interest in some circumstances, subject to treaties.

VAT is 5 percent for most supplies, with zero-rating for exports and some goods and services. The OTA is preparing further requirements such as e-invoicing, transfer pricing rules and compliance with global minimum tax standards for large multinational groups, so keep an eye on announcements. Customs duties, excise taxes and municipal fees may also apply.

Foreign-owned subsidiaries

A foreign-owned LLC is subject to the same filing duties as an Omani-owned company. Foreign investors benefit from the Foreign Capital Investment Law, which allows 100 percent ownership in most sectors, but investors should check any sector-specific restrictions and minimum capital rules in the licence.

Dividends and profit distributions are generally free from exchange controls, though banks will request approved accounts and evidence of tax compliance. Payments of fees and royalties to a foreign parent attract withholding tax unless reduced by treaty, and the parent should provide a tax residence certificate. Large groups should plan for transfer pricing documentation.

First-year and event-triggered obligations

In the first year, reserve the name, register the LLC through Invest Easy, obtain the commercial registration and licences, register with the OTA for corporate tax and VAT, register with PASI, open a bank account, and obtain work permits for staff. Event-driven filings include changes of partners, managers, capital, address and activities, and the renewal or amendment of licences.

Closing an LLC requires a liquidation process with creditor notices and clearance from the OTA, PASI and the Ministry of Labour. A dormant company still has filing duties, so file nil returns or close the company formally.

Employment and local requirements

Employers register employees with PASI and contribute for Omani nationals, with a lower contribution for expatriates in some cases. The Labour Law regulates contracts, working hours, leave, end-of-service gratuity and termination. Omanisation targets require a share of employees to be Omani nationals in many sectors, and non-compliance can lead to restrictions on work permits and fines. Expatriate employees require work permits and residence visas, and companies should plan for medical checks, fees and renewals. There is no personal income tax in Oman, but payroll compliance remains important.

Record-keeping and governance in Oman

Keep the commercial registration, articles, resolutions, audited financial statements, tax returns, VAT invoices, payroll and PASI records, and work permit files. Accounting records are generally kept for at least ten years, and tax records for the period required by the OTA. Maintain a list of authorised signatories, a calendar for registration renewals, lease renewals, OTA filings and Omanisation reports, and a record of Invest Easy and OTA portal users, since access depends on named individuals.

Build a compliance calendar for Oman

A compliance calendar turns the rules above into dated tasks with named owners. Start from the financial year-end and the incorporation anniversary, then add the recurring monthly and quarterly items. Review it each quarter, because deadlines, extensions and registry systems change.

• 60 days after establishment: register with the OTA for corporate income tax.

• Quarterly: VAT return and payment for registered companies.

• Before expiry: renew commercial registration, licences, lease and chamber membership.

• Four months after year-end, or the period confirmed by the OTA: corporate tax return with audited accounts.

• Annually: review Omanisation ratios and work permit renewals.

• Monthly: PASI contributions and payroll records.

Common mistakes

• Assuming a loss-making or exempt company does not need to register or file with the OTA.

• Relying on a provider's six month period without confirming the OTA's current rule.

• Missing the commercial registration renewal and being blocked from visa services.

• Forgetting withholding tax on fees and royalties paid to the foreign parent.

• Ignoring Omanisation targets until work permits are refused.

• Registering for VAT late after crossing the threshold.
