5% Personal Income Tax in Oman: Who Will Pay and Who Will Be Exempt

Oman’s new personal income tax has created a simple headline: 5% tax above OMR 42,000. The actual law is more nuanced.

Under Royal Decree 56/2025, the new Oman personal income tax will take effect on 1 January 2028, not in 2026 or 2027. The tax rate will be 5%, but it applies to taxable income, not automatically to a person’s entire salary or total gross earnings. Oman’s Tax Authority also estimates that around 99% of the population will not be subject to the tax because of the threshold and available exemptions and deductions.

That distinction matters for employees, expatriates, business owners, landlords, investors and anyone earning income from more than one source.

What Is Oman’s New 5% Personal Income Tax?

The Personal Income Tax Law was issued under Royal Decree 56/2025 on 22 June 2025 and published in Official Gazette 1602 on 30 June 2025. The law contains 76 articles across 16 chapters and becomes effective from 1 January 2028.

The headline rules are:

• Annual gross-income threshold: OMR 42,000
• Tax rate: 5%
• Taxpayer: A natural person who falls within the law
• Effective date: 1 January 2028
• Tax base: Taxable income after relevant exemptions, costs, losses and treaty relief

The OMR 42,000 threshold is therefore the starting point, not the final tax calculation.

The OMR 42,000 Threshold Does Not Mean Your Entire Income Is Taxed

One of the biggest misconceptions about 5% personal income tax Oman is that someone earning OMR 45,000 or OMR 50,000 will automatically pay 5% on the whole amount.

That is not how the Tax Authority currently explains the calculation.

The Tax Authority defines total income as the relevant cash amounts and in-kind benefits received by the taxpayer. Net income is the amount exceeding OMR 42,000, while taxable income is net income after deducting applicable exemptions, costs, losses and exemptions available under international agreements.

This means a person earning OMR 60,000 should not simply calculate 5% of OMR 60,000 and assume an OMR 3,000 tax bill.

The final amount depends on how the law applies to that individual’s income and reliefs.

Who Will Pay Personal Income Tax in Oman?

The tax is not restricted to Omani citizens.

Both residents and non-residents can fall within the new PIT regime, although the scope of their income differs.

Oman Tax Residents

A resident is generally an individual who is present in Oman for more than 183 days during a tax year, whether those days are continuous or intermittent.

According to published analysis of the law, resident individuals can be subject to tax on worldwide income, subject to exemptions, deductions, foreign tax credits and treaty provisions. The law applies to both Omani and foreign nationals.

This makes residency especially important for expatriates, internationally mobile executives and individuals with overseas investments or businesses.

Non-Residents

A person who does not meet the resident definition can still come within the PIT law where relevant income is realised in Oman.

Published guidance distinguishes non-residents from residents by generally limiting the non-resident tax scope to Oman-source income.

The question is therefore not simply:

“Are you Omani or an expat?”

The more important questions are where you are resident, where the income arises and what type of income it is.

Will Expats Pay Personal Income Tax in Oman?

Yes, expatriates can potentially pay Oman personal income tax from 2028.

Nationality does not create a general exemption. A foreign national who qualifies as an Oman tax resident can fall within the same PIT framework as an Omani national.

The outcome will depend on factors such as:

• residency status
• total annual income
• source of income
• foreign income
• applicable exemptions
• deductible expenses and losses
• double tax treaty provisions
• foreign tax already paid

A high-earning expatriate should therefore not assume that the new tax applies only to Omanis.

At the same time, an expatriate earning more than OMR 42,000 should not automatically assume that 5% will apply to every rial earned.

What Types of Income Can Fall Within the Oman PIT Regime?

The new regime is broader than salary.

Published summaries of the law identify a range of income sources that can enter the calculation.

• Salaries and employment income — including wages, allowances, bonuses, incentives and benefits in cash or kind
• Self-employment income
• Rental and leasing income
• Royalties
• Interest
• Returns from stocks, shares and bonds
• Returns from disposing of securities
• Returns from real-estate disposals
• Retirement pensions
• End-of-service benefits
• Prizes
• Certain grants and donations
• Director and board-member remuneration

This is why the OMR 42,000 threshold should not be treated as a salary-only threshold.

A person can potentially cross the threshold through several income sources combined.

Who Will Be Exempt From Oman Personal Income Tax?

There is not one single category called “exempt people.”

Instead, most people are expected to remain outside the tax charge because their total income will not exceed the threshold, while others may reduce taxable income through specific exemptions and deductions.

The Oman Tax Authority estimates that approximately 99% of the population will not be subject to PIT under the new regime.

Individuals Below the OMR 42,000 Threshold

Someone whose relevant total income does not exceed OMR 42,000 for the year will generally remain outside the tax charge under the basic threshold mechanism.

This is the main reason the regime is expected to affect a relatively small segment of the population.

People With Available Exemptions and Deductions

Crossing OMR 42,000 does not necessarily mean the entire excess becomes taxable without adjustment.

The Tax Authority has specifically highlighted exemptions and deductions relating to areas including:

• education
• healthcare
• inheritance
• zakat
• donations
• primary housing

The precise tax outcome will depend on whether the person satisfies the legal conditions for the relevant exemption or deduction.

Which Income and Expenses Can Receive Relief?

The law includes a number of social and economic relief mechanisms rather than relying only on the OMR 42,000 threshold.

Examples discussed in the law and professional summaries include:

The details matter.

For example, it would be inaccurate to say that every gift, every property transaction or every investment return is automatically exempt. The legal conditions need to be considered for the particular transaction.

Does Oman Tax Foreign Income?

For tax residents, foreign income can become relevant.

The Tax Authority defines total income for a resident as cash amounts and in-kind benefits received in Oman or abroad. For a non-resident, the definition is limited to relevant income received in Oman.

Published analysis of the law also confirms that residents can be subject to worldwide income while non-residents are generally taxed on income realised in Oman.

However, this does not necessarily mean foreign income will be taxed twice.

The regime provides for foreign-tax-credit mechanisms where tax has already been paid abroad on income that is also taxable in Oman. Double tax treaty provisions can also prevail over domestic law where applicable.

The law additionally contains special transitional treatment for certain foreign income after a person becomes an Oman tax resident.

Cross-border taxpayers should therefore avoid looking only at the 5% rate.

What If Someone Has More Than One Source of Income?

This will be one of the most important practical issues under Oman personal income tax 2028.

Consider someone with:

Looking only at salary would suggest that the person is below the OMR 42,000 threshold.

Looking at total income changes the picture.

The Tax Authority’s own FAQ gives an example of a person operating as a photographer without a commercial registration and earning OMR 50,000 annually. The Authority confirms that the person can be subject to PIT because the income exceeds OMR 42,000.

This shows that company registration or formal employment status does not determine PIT liability by itself.

How Will Salary Tax Be Collected?

Employers will have an important role in implementation.

The Tax Authority states that government entities, private-sector employers and foreign companies conducting activity in Oman will be required to deduct tax where relevant salaries or wages exceed the statutory level.

Deloitte’s analysis also identifies withholding obligations relating to:

• salaries
• pensions
• end-of-service benefits
• board remuneration

For employers, this means preparation will extend beyond payroll calculations.

Employee records, annual income information, withholding systems, reporting processes and supporting documentation may all need to be adapted before 2028.

Are Pensions and End-of-Service Benefits Taxable?

Pensions and end-of-service benefits should not simply be assumed to sit outside the regime.

The Oman Tax Authority expressly confirms that retirement pensions are among the sources considered within total income. Professional summaries of the law also list pensions and end-of-service benefits among relevant income categories.

That does not necessarily mean every pension or gratuity payment will suffer 5% tax without adjustment.

The threshold, available exemptions and other statutory rules still need to be applied.

How Much Personal Income Tax Could Someone Actually Pay?

The following examples show the basic mechanism before considering additional exemptions or deductions.

These are simplified illustrations.

Actual taxable income can be lower after qualifying exemptions, deductible costs, losses, treaty relief or foreign tax credits.

The key point is that 5% is applied to taxable income, not blindly to total gross income.

Does Oman Have Personal Income Tax Right Now in 2026?

No.

The law exists, but it has not yet entered into force.

Royal Decree 56/2025 expressly states that the Personal Income Tax Law comes into effect on 1 January 2028.

This distinction is important because announcements about the law can easily create the impression that Oman has already begun taxing personal income.

During 2026 and 2027, the focus is preparation and implementation rather than current liability under the new PIT regime.

What Is Still Developing Before 2028?

The primary law is final, but implementation does not stop with the Royal Decree.

Royal Decree 56/2025 requires the Chairman of the Tax Authority to issue executive regulations and other decisions required to implement the law.

The Tax Authority has also stated that electronic systems and guidance manuals are being prepared and introduced progressively.

Businesses and individuals should therefore distinguish between:

Rules already established in the law

and

Administrative details that may continue to be clarified before 2028

Areas likely to require close attention include filing mechanics, supporting documentation, payroll processes and how particular exemptions are evidenced.

What Should High Earners and Employers Do Before 2028?

There is time to prepare, but waiting until the first taxable year would create unnecessary pressure.

• Identify all income sources rather than monitoring salary alone
• Track tax residency days for internationally mobile individuals
• Separate Oman-source and foreign-source income
• Maintain evidence for qualifying education and healthcare expenditure
• Keep records of investments and property transactions
• Review foreign taxes already paid
• Check relevant double tax treaties
• Assess how pensions, bonuses and end-of-service benefits may affect annual income
• Prepare payroll systems for withholding obligations
• Monitor further Tax Authority regulations and guidance through 2027

For employers, the new regime is likely to require coordination between payroll, finance, tax, HR and mobility teams rather than being treated as a year-end employee calculation.

What the 5% Personal Income Tax Really Means for Oman

The most misleading interpretation of the new regime is:

“Anyone earning more than OMR 42,000 will pay 5% of everything they earn.”

The actual structure is more targeted.

The OMR 42,000 threshold first determines the portion of income entering the net-income calculation. Applicable exemptions, costs, losses and treaty relief can then affect taxable income. The 5% rate applies at that final taxable-income level. Residents and non-residents also have different income scopes, while employees, self-employed individuals, investors and landlords may need to consider more than salary alone.

For Finsoul Network Oman, the important issue through 2026 and 2027 is separating confirmed law from assumptions about how the system will operate in practice. The core framework is now clear, but individuals and employers should continue following Tax Authority regulations and implementation guidance before the regime becomes effective on 1 January 2028.

FAQs

Is Personal Income Tax Already Applicable in Oman in 2026?

No. Oman has enacted its Personal Income Tax Law, but Royal Decree 56/2025 specifies that it will enter into force on 1 January 2028. There is therefore no liability under the new 5% PIT regime during 2026 simply because the law has already been published.

Will Expats Pay Personal Income Tax in Oman From 2028?

Potentially, yes. The law applies to natural persons and does not provide a general nationality-based exemption for expatriates. Foreign nationals who qualify as Oman tax residents can fall within the regime, while non-residents may be taxed on relevant Oman-source income.

Is the Entire Salary Taxed If Income Exceeds OMR 42,000?

No. The Tax Authority defines net income as the amount exceeding OMR 42,000 and taxable income as net income after applicable exemptions, costs, losses and international-agreement relief. The 5% rate applies to taxable income rather than automatically to the individual’s entire gross salary.

What Income Is Exempt From Oman Personal Income Tax?

The law includes exemptions and deductions covering areas such as education, healthcare, inheritance, zakat, donations and primary housing, subject to applicable conditions. Individuals with total income below the OMR 42,000 threshold will also generally remain outside the tax charge.

Does Oman Personal Income Tax Apply to Foreign Income?

It can. Resident taxpayers can potentially fall within the regime on income received in Oman and abroad, while non-residents generally fall within the regime for relevant Oman income. Foreign tax credits and double tax treaty provisions can affect the final position where foreign income is involved.
