For a long time, running payroll in Oman was straightforward. There was no personal income tax, and the only statutory deduction most employers had to worry about was social insurance for Omani staff. That picture is changing. Oman has restructured its entire social protection system, extended coverage to expatriates for the first time, and passed a landmark law that will introduce personal income tax in 2028.
If you run payroll for a team in Oman, whether that is five people or five hundred, this article walks through exactly what payroll taxes in Oman actually involve today, what is changing over the next few years, and how to keep your business compliant through the transition. MFN Auditing helps businesses across Oman manage exactly this kind of shifting compliance ground, and this guide reflects the questions we hear most often from employers trying to plan ahead of the next deadline
Oman Has No Personal Income Tax, For Now
Let’s start with the headline point, because it still surprises many employers and employees new to the market. As of 2026, Oman does not levy a personal income tax on salaries. Take-home pay is your gross salary minus statutory social insurance deductions, nothing else. This has made Oman an attractive destination for expatriate professionals for decades, since most expats have historically had no employee-side deduction at all.
That is set to change, but not immediately. In June 2025, Oman issued Royal Decree No. 56/2025, introducing the country’s first Personal Income Tax Law. It applies a 5% tax rate on net annual income above OMR 42,000 (roughly USD 109,000), and it takes effect on 1 January 2028. This makes Oman the first GCC country to introduce a personal income tax on individuals, a genuinely significant shift for the region.
For now, though, the main deduction employers and employees need to understand is not an income tax at all. It is social insurance, run through Oman’s Social Protection Fund.
The Social Protection Fund: Oman’s Core Payroll Deduction
The Social Protection Fund (SPF) was established under Royal Decree No. 52/2023 and became effective on 1 July 2023. It replaced the older Public Authority for Social Insurance (PASI) system and, for the first time, extended statutory social protection to expatriate employees as well as Omani nationals, though the two groups are treated very differently.
Contributions for Omani Employees
Omani nationals working in the private sector are enrolled in the SPF, and contributions are shared between employer and employee. As of 2026, the combined contribution rate is 22.5% of salary, broken down as follows:
- Employee contribution: 8% (7.5% for pension or old-age insurance, plus 0.5% for employment security)
- Employer contribution: 14.5% (12% SPF core contribution, 0.5% employment security, and 1% maternity insurance)
On top of this, employers pay a further 1% for occupational disease and work injury coverage, which is fully employer-funded.
Contributions are calculated on the employee’s actual monthly wage, up to a salary ceiling of OMR 3,000 per month. Any salary above that ceiling is not subject to SPF contributions, which matters for structuring compensation packages for senior Omani staff.
To put this in concrete terms: an Omani employee earning a basic salary of OMR 500 a month would have OMR 37.50 deducted from their pay for SPF (7.5%), while the employer contributes a further OMR 67.50 (13.5%, before other add-ons), for a combined monthly SPF payment of OMR 105 for that one employee.
Contributions for Expatriate Employees
Expatriate employees are treated differently, and this is where Oman’s payroll requirements have shifted the most in recent years. Historically, expats had no ongoing social insurance contributions at all. Their only statutory protection was an end-of-service gratuity (ESG), typically calculated at 15 days’ basic wage per year of service for the first three years, and one month’s basic wage per year after that.
The SPF framework is gradually changing this, though the rollout has been delayed more than once to give employers time to adjust. Under Royal Decree No. 60/2025, several planned insurance schemes for expatriates were pushed back:
- Sick leave and other leave insurance, requiring a 1% salary contribution, has been postponed to July 2026 (originally planned for July 2025).
- Work injury insurance for non-Omani employees has been postponed to July 2028 (originally July 2026), with compensation of up to OMR 3,000 for workplace injuries.
- A mandatory savings scheme for expatriates, replacing the traditional end-of-service gratuity, has been postponed to 19 July 2027 (originally mid-2026).
That savings scheme deserves particular attention, because it represents the biggest structural change to expat compensation in the country’s history. Once it takes effect, employers will contribute 9% of an expatriate employee’s monthly basic wage into a provident fund managed by the SPF. The fund builds up monthly and becomes payable to the employee once their service in Oman ends, effectively replacing the old lump-sum gratuity with a more transparent, regulated savings mechanism.
For now, as of 2026, expatriate employees typically still have no employee-side SPF deduction. But employers should not treat this as a permanent state of affairs. The direction of travel is clear: more coverage, more contributions, and more payroll complexity for expat staff over the next two years.
What This Means for Employee Deductions Today
If you are processing payroll in Oman right now, here is a simple summary of the employee deductions Oman law currently requires:
For Omani national employees:
- 8% of salary deducted for SPF (7.5% pension, 0.5% employment security), capped at a monthly wage of OMR 3,000
- No personal income tax deduction (until 2028)
For expatriate employees:
- No standard SPF deduction as of 2026
- No personal income tax deduction (until 2028)
- Employers should expect a 9% employer-funded savings scheme contribution to begin from July 2027, plus sick leave and work injury insurance contributions phasing in through 2026 and 2028
This means, for the moment, net pay for expatriate staff in Oman is essentially their gross salary. That will not remain the case indefinitely, and any employer with expat staff on multi-year contracts should be modeling these upcoming costs now rather than waiting for the deadlines to arrive.
The Real Cost of Employment in Oman: What Employers Should Budget For
Because so much of Oman’s system is employer-funded, the real cost of employing someone is higher than the gross salary on the offer letter. For an Omani employee, a business should budget for roughly 14.5% to 15.5% on top of gross salary once the standard SPF and injury insurance contributions are included. For expatriate employees, current on-costs are lower, but that gap is closing. Employers with expat-heavy workforces should factor in the incoming 9% savings scheme contribution and the phased insurance requirements when forecasting labor costs for 2027 and beyond, alongside existing end-of-service gratuity liabilities that remain in place until the new scheme fully replaces them.
There is also the Wage Protection System (WPS) to account for operationally, if not financially. WPS is a government-mandated electronic salary transfer system, run jointly by the Ministry of Labour and the Central Bank of Oman, that requires registered private sector employees to be paid correctly, in full, and on time through an auditable electronic channel. It does not add a cost in the way SPF contributions do, but it does mean payroll accuracy and timing are now subject to direct government oversight, and errors or late payments are far easier for regulators to spot than they once were.
Getting Ready for 2028: Personal Income Tax
While 2028 might feel a long way off, the compliance groundwork for Oman’s Personal Income Tax Law needs to start well before then. A few details are already clear from the published decree and early guidance from the Oman Tax Authority:
- The tax applies to individuals, both Omani and expatriate, whose annual net income exceeds OMR 42,000, at a flat rate of 5% on the amount above that threshold.
- Tax residents will be taxed on worldwide income; non-residents only on Oman-sourced income.
- Deductions are expected to be available for items such as education expenses, healthcare costs, charitable donations, and interest on loans used to finance a primary residence.
- Executive regulations, which will clarify the finer mechanics of withholding, filing, and exemptions, are due within a year of the law’s publication.
- Employers will be responsible for monthly withholding once the law takes effect, meaning payroll systems need to be able to tag taxable employees, calculate net income against the threshold, and withhold accordingly.
For employers, particularly those with a mix of high-earning Omani and expatriate staff, this is a good moment to start reviewing compensation structures, since salaries above roughly OMR 3,500 a month will eventually cross the annual OMR 42,000 threshold. HR and finance teams should also expect contract and offer letter language to evolve, as employers weigh whether to quote packages gross or net once withholding begins.
Why Many Businesses Choose to Outsource
Given how much the rules have shifted in just the past three years, and how much more is coming through 2027 and 2028, it is easy to see why many companies operating in Oman lean on specialist payroll services Oman providers rather than trying to track every regulatory change in-house. A good payroll partner keeps pace with SPF rate changes, manages the transition to the expatriate savings scheme, ensures WPS compliance, and will be essential once income tax withholding becomes mandatory in 2028.
This is especially useful for foreign companies setting up their first Omani entity, or for growing businesses that do not yet have a dedicated in-house payroll or tax function. Getting local Oman payroll requirements wrong, even unintentionally, can mean penalties, back-payments, or reputational damage with the Social Protection Authority, so getting it right from day one is worth the investment.
Get Your Oman Payroll Ready for What’s Ahead
Oman’s payroll landscape is no longer the simple, tax-free system it was a few years ago. Between the Social Protection Fund’s evolving contribution rates, the phased rollout of expatriate coverage, and a personal income tax arriving in 2028, employers now have a genuine compliance timeline to manage rather than a fixed set of rules to learn once. Getting ahead of each phase, rather than reacting to it, is what keeps payroll accurate and protects a business from penalties or back-payments down the line.
As a firm working closely with businesses across Oman, MFN Auditing helps employers stay ahead of SPF rate changes, prepare for the expatriate savings scheme, maintain WPS compliance, and get payroll systems ready for 2028’s income tax withholding requirements well before the deadline pressure builds. If you would rather have this handled by people who track every regulatory update as it happens, our team is ready to help you build a payroll process that stays compliant no matter how Oman’s rules continue to evolve.
Frequently Asked Questions
Does Oman currently have a personal income tax?
No, not yet. Oman has no personal income tax on salaries as of 2026. A 5% tax on net income above OMR 42,000 a year was signed into law under Royal Decree No. 56/2025 and takes effect on 1 January 2028.
What percentage of salary goes to Social Protection Fund contributions for Omani employees?
Omani nationals contribute 8% of salary (7.5% pension plus 0.5% employment security), while employers contribute a further 14.5%, bringing the combined rate to 22.5%. Contributions are calculated on wages up to a monthly ceiling of OMR 3,000.
Do expatriate employees pay into the Social Protection Fund?
As of 2026, most expatriate employees have no standard SPF deduction from their pay. However, employers will need to contribute 9% of an expat employee’s basic wage into a new mandatory savings scheme starting July 2027, along with phased sick leave and work injury insurance contributions through 2026 and 2028.
How can employers prepare for Oman’s upcoming payroll changes?
Start by reviewing current compensation structures against the OMR 42,000 income tax threshold and the OMR 3,000 SPF salary cap, and build the incoming expatriate savings scheme contributions into 2027 and 2028 budgeting. Many employers work with specialist payroll providers to stay compliant as these rules are phased in.
