Understanding Corporate Tax Administration in OMAN

Navigating corporate tax administration is crucial for businesses operating in Oman. This article provides a comprehensive overview of key aspects such as taxable periods, tax returns, payment procedures, objections and appeals, statute of limitations, record maintenance, and areas of focus for tax authorities.

1. Taxable Period

In Oman, the taxable period generally aligns with the calendar year. However, businesses can opt for a different year-end, subject to prior approval from the Oman Tax Authority (OTA). It’s essential to maintain consistency once a year-end is chosen. Notably, a taxpayer’s first tax year can extend up to 18 months, allowing flexibility during initial establishment.

2. Tax Returns

Filing Requirements

Businesses must file a single ‘return of income’ within four months after the financial year ends. Extensions for filing are at the OTA’s discretion and do not delay tax payment, which incurs an additional 1% per month if late.

Documentation

The annual return should be supported by audited accounts, signed by a registered auditor in Oman. Accounts must adhere to International Financial Reporting Standards (IFRS) or similar standards approved by the OTA and should be prepared using accrual accounting unless otherwise permitted. The submission should be in local currency unless prior approval for foreign currency is obtained.

SMEs

Small and Medium Enterprises (SMEs) taxed at 3% must file returns with a simplified income statement within three months of year-end.

Penalties

Delays or failures in filing can lead to penalties ranging from OMR 100 to OMR 2,000. Incomplete returns or failure to submit audited accounts can prompt an estimated profit assessment by the OTA. The OTA holds significant power to request detailed information, and failure to comply can result in additional assessments or penalties.

3. Payment of Tax

Due Dates and Interest

Taxes must be paid with the final return, due within four months of year-end. Late payments incur a 1% monthly interest. Instalment payments are possible with prior OTA approval.

Additional Assessments

Differences between paid and assessed amounts should be settled within a month of assessment, accruing 1% monthly interest if late. The OTA can sequester and sell assets to recover unpaid taxes.

Refunds

Taxpayers may recover overpaid taxes, adjusted against future liabilities if applicable, within five years from the tax year end. Failure to declare correct income can result in fines ranging from 1% to 25% of the underreported amount.

4. Objections and Appeals

Businesses can object to OTA assessments within 45 days, in both English and Arabic. The OTA must respond within five months, extendable by three months. During this period, additional taxes are not required. Post-decision, immediate payment is necessary, with no further deferment.

Further grievances can be addressed to the Tax Grievance Committee within 45 days of the objection decision. Decisions by the Primary Court can be appealed to the Court of Appeal and subsequently to the Supreme Court, following the Civil and Commercial Procedures Law.

5. Statute of Limitations

Under the self-assessment regime introduced by Royal Decree 9/2017, the OTA has three years from the end of the tax return submission year to conduct assessments. For entities that do not submit returns, the period extends to five years.

6. Maintenance of Records

Businesses are required to maintain accounting records and supporting documents for ten years following the end of the relevant accounting period. This ensures compliance and facilitates any future audits or reviews.

7. Focus Areas for Tax Authorities

Related-party transactions are scrutinized closely by the OTA. Businesses must maintain extensive documentation to demonstrate that transactions are conducted at arm’s length, ensuring compliance with transfer pricing regulations.

Summary

The tax system in Oman operates on a calendar year basis, but businesses can request different year-ends with OTA approval. Taxpayers must file accurate returns, including audited accounts based on international standards, within four months after the financial year ends. Late filings incur penalties and interest.

Payment of taxes should accompany the final return within the deadline, with options for instalment payments under specific conditions. Taxpayers can object to assessments within 45 days, with decisions expected within a set timeframe. The OTA has the authority to request detailed financial information and impose fines for non-compliance.
