Oman Personal Income Tax 2028: What Individuals and Businesses Need to Know
Oman’s Personal Income Tax Law is already enacted, but the tax itself does not begin until 1 January 2028. That gap matters. For individuals, it creates time to understand which income may fall within the new regime. For employers, it creates a preparation period for payroll, withholding, employee data and compliance processes. Under Royal Decree 56/2025, Oman personal income tax 2028 introduces a 5% rate on taxable income under the new framework, with an annual gross-income threshold of OMR 42,000. The Oman Tax Authority expects approximately 99% of the population to remain outside the tax charge. The impact will therefore be concentrated, but businesses cannot treat PIT as an issue affecting only a small number of high earners. Employers themselves will have responsibilities within the collection and reporting framework. What Changes on 1 January 2028? Oman’s Personal Income Tax Law becomes effective on 1 January 2028. It applies to natural persons rather than creating another corporate tax on businesses. The basic framework uses an OMR 42,000 annual gross-income threshold and a 5% rate applied to taxable income. For individuals, the change means salary will no longer be the only number worth monitoring. Other relevant income can enter the calculation. For businesses, the change introduces an employer-side compliance dimension because withholding and remittance can become part of payroll administration. Area What changes from 2028 Individuals Qualifying natural persons can become subject to PIT Annual threshold OMR 42,000 Tax rate 5% of taxable income Employers Withholding and related compliance responsibilities can apply Cross-border individuals Tax residency and foreign income become important Records Evidence supporting income, costs and reliefs becomes more important The new regime should therefore be viewed as both an individual tax change and an employer-readiness project. Who Needs to Pay Attention Before 2028? Not everyone needs the same level of preparation. The priority should be people and organisations most likely to interact with the new regime. Higher-earning employees: Individuals approaching or exceeding OMR 42,000 in annual income need to understand what enters their total income calculation People with multiple income sources: Salary, rental income, self-employment and investment returns can make the annual position different from salary alone Internationally mobile individuals: Days spent in Oman and overseas can become relevant when determining tax residency People with foreign income: Oman tax residents may need to consider overseas income and foreign taxes already paid Employers: Businesses need to understand withholding, payroll and employee-information requirements before implementation HR and payroll teams: Compensation data, benefits, bonuses and employee records will need to support the new tax process Businesses with internationally mobile staff: Expatriate packages, assignments and cross-border compensation may require additional review** How Will Oman Personal Income Tax Be Calculated? The 5% headline rate does not mean that an individual earning OMR 60,000 will automatically pay 5% of OMR 60,000. The Tax Authority distinguishes between total income, net income and taxable income. In broad terms, the calculation starts with relevant annual income. The OMR 42,000 threshold is then considered, followed by applicable exemptions, costs, losses and relief available under relevant international agreements. Total income → Amount above OMR 42,000 → Applicable exemptions, costs and losses → Taxable income → 5% For example, if an individual has OMR 50,000 of relevant annual income, the amount above the basic threshold is OMR 8,000. If no further adjustment applied, 5% of OMR 8,000 would be OMR 400. Actual liability can differ where the law permits further exemptions or deductions. What Individuals Need to Do Before 2028 Individuals do not need to wait for the first 2028 payslip before understanding their potential position. Three areas deserve particular attention during the preparation period. Identify All Sources of Income Salary is only one potential component of total income. The new law covers a wider range of sources, including employment income, self-employment, rent, interest, investment returns, royalties, pensions, end-of-service benefits and board remuneration. Someone earning OMR 35,000 from employment could therefore still need to examine the regime if significant rental, investment or other income takes total annual income beyond the threshold. Maintaining a clear annual view of different income sources will become more important than looking at basic monthly salary alone. Track Oman Tax Residency Tax residency can determine the scope of income entering the Oman tax framework. Published analysis of the law uses presence in Oman for more than 183 days during the tax year, continuously or intermittently, as the key domestic-law residency test. This becomes particularly relevant to expatriates, executives working across GCC countries and individuals who divide their year between Oman and another jurisdiction. Travel records that previously had little relevance to personal taxation may become important evidence when establishing an individual’s tax position. Keep Evidence for Available Reliefs The law contains exemptions and deductions relating to areas such as education, healthcare, zakat, qualifying donations and housing, subject to applicable conditions. Foreign tax paid can also become relevant in cross-border cases. Individuals who may fall within the regime should therefore develop better record-keeping habits before 2028. Receipts, payment records, investment statements, foreign tax documentation and evidence supporting eligible expenditure can become important when determining taxable income rather than merely gross income. What Does Oman Personal Income Tax Mean for Expats? The new tax is not an “expat tax.” It is also not restricted to Omani nationals. An expatriate who satisfies the applicable Oman tax-residency conditions can fall within the regime. For residents, foreign income can also become relevant, subject to the provisions of the law, available exemptions, foreign tax credits and applicable double tax treaties. For internationally mobile employees, this makes the Oman personal income tax for expats question more complex than checking annual salary. Residency days, overseas income, foreign tax and the terms of international assignments may all influence the eventual position. Why Foreign Income Will Require Better Records For an Oman tax resident, the new regime can extend beyond income received locally. The Tax Authority’s published FAQs describe total income for residents as including relevant amounts and benefits received in Oman or abroad. That makes documentation
