With the enactment of Royal Decree No. 56/2025, His Majesty Sultan Haitham bin Tarik has introduced Oman’s first-ever Personal Income Tax (PIT), set to take effect on January 1, 2028.

As a result, approximately 99% of the population is expected to remain exempt from taxation.

Deductions & Exemptions

All residents and non-residents with a gross annual income exceeding OMR 42,000 must:
- File an electronic tax return within a six-month window following the end of the relevant tax year.
- Pay the due tax amount simultaneously along with filing the tax return.
Employers are required to withhold income tax from salaries, pensions, end-of-service benefits, and board remuneration. Failure to comply may result in penalties, interest, or administrative sanctions.

Moving Forward for Individuals & Employers
As Oman prepares to implement its first Personal Income Tax (PIT) regime in 2028, it is vital for both individuals and employers to take proactive measures to ensure full compliance and smooth adaptation to the new regulations. Here are some guide on how to prepare:
For Individuals:
Track Residency Days and Foreign Income
Carefully monitor and record the number of days spent within Oman to accurately determine your residency status, which affects tax liability. Additionally, keep detailed records of any foreign income earned, as this may impact your reporting obligations and exemptions.
Retain Receipts for Deductible Expenses
Maintain organized documentation of deductible expenses such as tuition fees, medical bills, health insurance, and charitable donations like Zakat. These receipts will be essential when claiming exemptions or deductions on your tax return.
Declare All Forms of Non-Cash Benefits
Be transparent and document benefits-in-kind received from your employer, such as company-provided housing, cars, stock options, or other in-kind perks. Proper declaration of these benefits is vital for accurate tax reporting and compliance
For Employers:
Update Payroll and HR Systems
Modify existing payroll software to incorporate automatic withholding and remittance of income tax from employee salaries, pensions, end-of-service benefits, and board member remuneration. Ensure your systems are capable of accurately calculating withholding based on the new thresholds and rates.
Classify Benefits-in-Kind Properly
Clearly differentiate between employee benefits-in-kind (such as housing allowances, transportation, or stock options) and regular salary components. Proper classification ensures correct tax reporting, appropriate tax treatment, and compliance with legal obligations.
Prepare for Electronic Reporting and Withholding
Establish procedures for electronic submission of tax declarations and real-time withholding of taxes, as mandated by Oman’s tax authority. Train HR and payroll personnel on the new reporting platforms and deadlines to avoid penalties or delays.
Enhance Record-Keeping and Documentation
Maintain detailed records of taxable income, benefits, and withheld amounts. Proper documentation will facilitate compliance during audits and help resolve any disputes swiftly.
A Pioneering Move In the Gulf Region
As the first Gulf country to implement personal income tax, Oman’s decision signifies a groundbreaking shift in the regional economic and tax landscape. This move represents more than just fiscal policy—it’s a strategic effort to diversify revenue streams, attract regional and international investment, and strengthen economic resilience. Oman’s initiative setsa precedent that could influence neighboring countries to reconsider their own tax frameworks in the future.
While other Gulf nations have yet to introduce similar measures, Oman’s bold step is expected to draw significant regional and global attention. Its impact will be closely monitored, and the broader Gulf region may gradually adapt to this new norm of tax transparency and compliance. The Oman Tax Authority is anticipated to release further guidance, detailed regulations, and clarification on compliance procedures as the rollout approaches.
