Legal System of Oman for Taxation

Islamic Sharia Law and civil code laws are combined to form Oman's legal framework. The system is governed by several regulations regarding taxes and customs duties.

  • Oman's income tax is governed by the Income Tax Law, established by Sultani Decree 28/2009 and amended by Sultani Decree 9/2017.
  • The Social Securities Law, which handles social security issues in the country, was established by Sultani Decree 72/1991.
  • The Commercial Company laws describe the regulatory framework for business operations in Oman, including the formation, management, and governance of firms.

Types of Taxes in Oman

  • Corporate Tax:The corporate tax is the primary tax that businesses in Oman are required to pay. Oman does not have a limit on the amount of revenue, in contrast to certain countries. For the majority of businesses, the company's tax rate is15% of profits.Two categories of companies are subject to this 15% tax: Companies and commercial organizations based in Oman, including their branches and foreign companies working in Oman.

Zero rating and exceptions are included in the Oman VAT Law. Oman's 5% VAT rate is regarded as one of the lowest in the world by comparison. When a company's yearly supply value surpasses OMR 38,500, it must register for VAT. The tax will be applied to most products and services, although there are several exceptions. According to a royal proclamation, the proposed charge will not apply to essential food goods, healthcare, education, or financial services.

A 10% WHT is due if an international individual or company has no permanent presence in Oman. Typically, this sum is subtracted by the company making the payment before it is sent to the foreign party.

No taxes are levied on payments made by Limited Liability Companies (LLCs) as profit distributions to their overseas owners. However, profits paid by Omani joint-stock businesses are subject to WHT.

Which taxes are not levied in Oman?

Oman does not levy:

  • Any local income taxes
  • Property taxes
  • Stamp duty
  • Payroll taxes
  • Environmental taxes
  • Personal Income Tax

Tax Returns

A tax return is a statutory necessary paper that individuals and companies must file with the Omani tax authorities to report their financial data and determine how much tax they owe. A tax return is an essential part of the taxation system that allows taxpayers to satisfy their duties and guarantee that they follow all tax laws.

In Oman, individuals and entities must submit a "return of income" within four months after the fiscal year's end. However, according to the Tax Authority's (TA) decision-making, it is possible to ask for a filing extension for the yearly income tax returns. It is essential to remember that even if an extension is approved, tax payments cannot be put off. A monthly tax charge of 1% will be added to any unpaid tax balance from the time it was first due until the time it was paid.

Tax Period

The first financial year can be up to eighteen months. The calendar year is the tax year generally followed in Oman. The financial year ends on December 31, in case approval has been taken to follow a different financial year from Oman tax authorities.

International Tax Treaties

International tax treaties, usually called double taxation treaties, are essential for promoting cross-border commerce and investment to minimize the negative impacts of double taxation. In order to foster economic cooperation and reduce double taxation, Oman has signed various tax treaties as a member of the global community. Oman has signed tax treaties with over 30 countries, proving to be a great asset for business owners and entrepreneurs looking to develop internationally more quickly.

Penalty for Late Payment of Taxes

The tax authorities have the right to issue a fine ranging from 1% to 25% of the difference between the correct income, which is taxable, and the tax amount declared in the returns in case where a taxpayer incorrectly discloses their income. If the taxes are not paid by the given deadline, interest will start to accumulate till the date of payment made at the rate of 1% per month.
