Corporate Tax in Oman: A Practical Guide for New Businesses

Getting familiar with the applicable taxes in your investment destination, such as Oman, is a key part of opening your company, maintaining business continuity, and adhering to the local law. One of the important taxes that businesses should consider is the corporate tax in Oman, which is also known as the corporate income tax

But what is this tax exactly? What is the corporate tax rate in Oman? Does it apply to foreign companies established in the Sultanate? And how can you fulfil this tax obligation? Our guide offers the answers to these questions and more valuable insights. 

What is Corporate Tax in Oman?

The corporate tax, or corporate income tax, in Oman ​refers to the tax that businesses operating in the Sultanate pay on their taxable income earned during a tax year. Therefore, it is not imposed on the company’s total revenue but on its taxable income after allowable business expenses have been deducted. 

  • What is the Corporate Tax Rate in Oman

The standard corporate tax rate in Oman is a flat 15% of taxable income for most companies. Smaller businesses, however, can benefit from a reduced rate of 3% but only if they meet certain qualifying criteria, including: 

  • The capital registered does not exceed OMR 60,000. 
  • The gross annual income is OMR 150,000 maximum. 
  • There are no more than 25 employees. 
  • The business does not carry out certain excluded activities, such as insurance and natural-resource extraction. 

It is worth noting that the Oman corporate tax rate is significantly higher for oil exploration companies, as it can reach 55% of the taxable income. The rate varies depending on the concession agreements that companies make with the Omani government.

Who is Subject to the Oman Corporate Income Tax​?

Corporate tax in Oman generally applies to the following types of businesses and companies: 

1- Omani Companies 

Companies incorporated and registered in Oman, whether owned by Omani or foreign investors, across various sectors. 

2- Foreign-Owned Companies in Oman

Corporate tax in Oman also applies to fully or partially foreign-owned companies, regardless of their corporate structure, including SPCs, LLCs, and other permitted company types.

What Income is Subject to Corporate Tax in Oman?

The corporate tax applies to income earned from qualifying business activities conducted in Oman, including industrial, commercial, and professional activities. Accordingly, the tax is imposed on the following: 

  1. Income Earned by Companies Established in Oman: This is the income generated by companies incorporated and registered in the Sultanate from carrying out qualifying activities. These companies may be owned by either Omani or foreign investors.
  2. Income Generated by Foreign-Owned Companies Operating in Oman: Foreign companies established abroad but doing business in Oman through a qualifying business presence are also subject to the corporate tax on the income generated from their activities in Oman. 

That being said, the tax rules applicable to income can vary depending on its nature and source, potentially affecting how it is classified and whether or not exemptions, deductions, or other tax provisions apply.

So, how is the Oman corporate income tax​ calculated? Below is a simplified example that can help you understand this financial obligation. 

How to Calculate Corporate Tax in Oman

The corporate tax in Oman is applied immediately after the company’s first Omani Rial of profit with taxable income calculated by deducting operational expenses and other applicable adjustments from the company’s total income within the relevant tax year. 

These deductions include business expenses like salaries and office rent, in addition to other adjustments like depreciation, which accounts for the decline in the value of certain business assets, such as machinery, over their useful life.

The following example shows you how to calculate the corporate tax in Oman assuming that the applicable rate is the standard 15%. Suppose your company earned OMR 100,000 in total revenue during one tax year. You’ll first need to deduct the allowable business expenses from this amount to determine the taxable income. 

Here is the general formula for calculating the corporate tax in Oman

Total revenue − Operating expenses (COGS) = Profitable Taxable income 

OMR 100,000 − OMR 30,000 = OMR 70,000

Then, you multiply the taxable income by 15%: 

Taxable income × 15% = Corporate tax

OMR 70,000 × 15% = OMR 10,500 

The company would owe OMR 10,500 in corporate tax. 

It is important to note that you cannot subtract every business expense from the revenue. Only the expenses that are directly related to the company’s business activities and meet the requirements set by tax authorities are deductible. 

How to Stay Compliant and Manage Corporate Tax in Oman

Corporate income tax is an important business tax in Oman, making it necessary for businesses to understand this tax obligation and comply with its applicable rules, rates, and regulations. Here are the steps you should follow to successfully manage and remain compliant with corporate tax in Oman:

  • Register for Corporate Tax in Oman with the Relevant Authority 

Businesses must register for the Oman corporate income tax by registering with the Oman Tax Authority through its official electronic portal, using the Taxpayer Registration online service. The application requires you to submit the necessary business information and supporting documents. After registration is complete, you will obtain your tax file number for future tax-related procedures. 

This registration is essential for companies carrying out business activities in Oman, as it officially establishes their tax obligations and supports ongoing adherence to applicable tax rules and regulations. Companies must get this procedure completed within 60 days of establishment or commencement of business activities—whichever comes first. 

  • Maintain Accurate Financial Records 

To be compliant with corporate tax in Oman and avoid errors, you must maintain accurate and up-to-date financial records. This generally includes tracking income and expenses regularly, keeping receipts, invoices, and other supporting documents, reconciling bank accounts monthly, and using reliable accounting software. Maintaining these records provides a solid foundation for accurate tax calculations and ongoing compliance. 

  • Monitor Taxable Income 

You should check how much of the company’s income is actually taxable for the corporate tax, helping you estimate your tax liability and ensuring that tax filings and payments are prepared accurately and timely. You can do this by performing the needed calculations regularly, such as on a monthly basis. 

This process involves tracking revenue, identifying the taxable income, and accounting for the allowable business expenses and other applicable adjustments. Then, you can apply the applicable tax rate to calculate the estimated tax amount payable.

  • Understand Applicable Deductions 

Thoroughly understanding what qualifies as an allowable deduction is crucial for maintaining accurate financial records and calculating tax liability correctly. These allowable deductions refer to the business expenses and other amounts that can be subtracted from the total revenue to identify the income subject to the Oman corporate tax

According to the Oman Tax Authority, allowable expenses are amounts actually spent by a company for the purpose of generating its gross income, provided they meet the applicable conditions. These include being genuine and actually spent, being related to the company’s business activities, being properly recorded in the accounting records, and being supported by the required documentation.

Some of the allowable expenses include: 

  • Office rent.
  • Operational costs. 
  • Salaries. 
  • Business-related expenses. 
  • Pension contributions. 

This only emphasises that not every business expense is deductible, making your understanding of this distinction crucial for ongoing compliance and proper corporate tax management. 

  • Tax Filing

The next step of how to remain compliant with the corporate income tax in Oman is filing the annual tax return. The tax return is essentially the company’s annual tax report submitted to the Tax Authority, detailing its tax position and providing the required supporting documentation. It generally includes the company’s income, allowable expenses, taxable income, applicable tax calculations, and other information required by the Oman Tax Authority.

This step requires you to prepare and submit the annual tax return on time, ensuring you do not miss applicable deadlines. Companies in Oman generally submit their tax return annually within 40 working days of their financial year end and pay any tax due according to the relevant requirements. 

Practically speaking, companies can pay any tax due through the Oman Tax Authority online portal using the available payment methods. 

  • Review Tax Obligations Regularly 

Tax regulations and rules, including exemptions, incentives, requirements, and rates, can change from time to time, while new taxes can also be introduced, like the Personal Income Tax that will be taking effect beginning 2028. Therefore, you should prioritise staying up to date with the latest applicable tax regulations, ensuring that you are legally compliant with the local law at all times.
