In a landmark fiscal development for the Gulf region, Oman has officially introduced a personal income tax law, becoming the first member of the Gulf Cooperation Council (GCC) to implement a direct tax on individual earnings. This move marks a significant evolution in the region’s taxation landscape, traditionally dominated by indirect taxes such as VAT and customs duties.
Royal Decree No. 56/2025, issued on 22 June 2025, establishes Oman’s Personal Income Tax Law, which will come into effect on 1 January 2028. The law will be published in the Official Gazette on 29 June 2025, and detailed executive regulations are expected within a year.
Key Elements of the New Personal Income Tax Law
Tax Scope and Rate
- A flat 5% personal income tax will apply to natural persons (individuals) whose gross annual income exceeds OMR 42,000 (approx. USD 109,200).
- Gross income includes all receipts in cash and kind—capturing salary, property income, royalties, and more.
Income Categories Potentially Subject to Tax
- Employment income (e.g., salaries and wages)
- Income from real estate and immovable property
- Royalties or earnings from industrial and intellectual property
Exemptions and Deductions: A Progressive Approach
Despite the introduction of income tax, Oman has taken a measured, equity-focused approach by building in substantial exemptions and deductions. This ensures that the vast majority of the population—estimated at 99%—will not be affected.
Key Exemptions (Subject to Executive Regulations)
- Foreign-sourced income (exempt for the first two years following implementation)
- Capital gains from the sale of:
- Primary residence (fully exempt)
- Secondary residence (exempt once per individual)
- Inheritance and gifts
- Income from registered industrial property rights (exempt for 5 years from date of registration)
Allowable Deductions
- Education expenses (e.g., tuition for dependents)
- Healthcare costs
- Religious and charitable contributions (e.g., zakat, waqf, donations)
- Home loan interest for acquisition or construction of a primary residence (one-time deduction)
Why This Matters: Regional and Economic Implications
Oman’s move represents a paradigm shift for taxation in the Gulf, where most countries have long avoided direct income taxes. This reform is part of Oman’s broader strategy to:
- Diversify its economy away from hydrocarbons
- Reinforce social protection programs
- Align with the national development agenda outlined in Oman Vision 2040
Globally, Oman’s personal income tax regime will stand out for its high exemption threshold and low flat rate, positioning it as socially responsible while still effective in broadening the tax base.
Preparing for 2028: Strategic Considerations
For Employers
- Payroll systems must be updated to handle tax withholding and reporting.
- Employment contracts, expatriate packages, and benefits structures should be reviewed to ensure compliance and competitiveness.
- Talent acquisition and retention strategies may need to evolve in light of increased cost of employment.
For Individuals
- High-earning residents—particularly those with multiple income streams—should begin financial planning to understand the impact on net income.
- Asset owners and landlords should assess how income from property fits into the taxable base.
- Early preparation offers opportunities to optimize deductions and structure earnings efficiently before the law takes effect.
Next Steps and Regulatory Timeline
While the law is now official, further details—including compliance mechanisms, tax filing procedures, and definitions of taxable categories—will be clarified in the executive regulations, expected within 12 months of publication in the Official Gazette.
Businesses, financial institutions, and individuals will have until January 2028 to prepare for compliance.
Conclusion
Oman’s introduction of personal income tax is not just a domestic fiscal reform—it sets a precedent for the entire GCC. By implementing a modest, high-threshold tax with built-in social protections, Oman has taken a cautious yet forward-looking step toward long-term economic sustainability.
The early lead time offers a critical window for businesses and individuals to adapt, plan, and optimize their approach to this historic policy change.
