Oman WPS Update: Compliance Guide for Private Sector Employers

Oman's Ministry of Labour issued Ministerial Decision No. 729/2024 on December 15, 2024, updating the Wage Protection System framework for the private sector. The decision came into force the following day and introduced tighter transfer timelines, new exemption categories, and phased workforce coverage targets that concluded through 2025, bringing Oman to full universal compliance.

This guide covers:

• What Ministerial Decision No. 729/2024 changed and what it replaced
• How Oman's WPS works and where it stands in the GCC landscape
• The 3-day transfer deadline and the now-concluded phased compliance rollout
• Exemptions, and how they apply in practice
• The enforcement sequence and penalties for non-compliance
• What your HR and payroll team needs to do to stay compliant

Where Oman's framework differs from or compares with other GCC countries, those points are drawn in — they add useful context to Oman's specific requirements.

Oman WPS: Quick Summary

• Governing regulation: Ministerial Decision No. 729/2024, effective December 16, 2024. Replaces Ministerial Decision No. 299/2023.
• Transfer deadline: Wages must be transferred within 3 days of the end of the wage entitlement period. The UAE's 1st-of-month deadline is the tightest in the GCC; Oman's 3-day window is the second tightest.
• Coverage:
  Oman's phased rollout concluded in late 2025. Universal private sector compliance is now expected by the Ministry of Labour
• Payment channel: Transfers must go through banks or financial institutions regulated by the Central Bank of Oman. Cash and informal arrangements are not compliant.
• Contract update obligation: Employers must update employment contracts whenever a worker's wage changes. The contract must reflect the actual salary.
• Exemptions exist but are specific: New joiners under 30 days, workers on unpaid leave, labour disputes with work stoppages over 30 days, absconding cases, and work suspensions beyond the employer's control.
• Penalties: Warnings, suspension of preliminary work permit services, and fines of OMR 50 per worker, doubling for repeated offences.
• greytHR covers Oman and the GCC: SIF file generation, EOSB calculations, configurable payroll cutoffs, and audit-ready records across GCC jurisdictions on one platform.

How Oman's WPS Framework Works

Oman's Wage Protection System has been in development since 2016, with technical specifications established by the Ministry of Labour. It became mandatory for private sector employers in July 2023 under Royal Decree No. 53/2023, rolling out in phases beginning with larger enterprises and progressively covering smaller businesses. greytHR built its Oman WPS integration ahead of the mandate, working from the Ministry's specifications, giving customers a compliance-ready solution well before the rollout reached full enforcement.

The WPS is administered by the Ministry of Labour (MoL), which maintains a designated division responsible for monitoring wage payments and building a database of transactions. Payments must flow through banks or financial institutions regulated by the Central Bank of Oman, creating a traceable, auditable chain from employer to employee.

One important piece of context for HR teams, particularly those managing payroll across the GCC: Oman's WPS reached full universal scope more recently than its GCC counterparts. As of early 2025, around 99,000 private sector businesses had registered, but only roughly 25% had successfully processed wages through the system. The Ministry of Labour pushed compliance through phased targets and repeated enforcement reminders across 2025. Those targets have now concluded, and full private sector compliance is the standing expectation. For HR teams, that means the compliance conversation in Oman has shifted from whether to participate in WPS to whether your process meets its requirements.

Oman's WPS reached its full compliance mandate faster than most employers anticipated. The Ministry of Labour has moved past nudging employers toward the system. It is enforcing full participation. Employers who have not yet completed their WPS integration are operating with a risk profile that has no remaining buffer.

The 3-Day Transfer Deadline: Oman's Tightest Requirement

The most operationally significant change under Ministerial Decision No. 729/2024 is the transfer timeline. Employers must now transfer wages to employees' accounts within 3 days of the end of the wage entitlement period. This replaced a 7-day window that existed under the previous Ministerial Decision No. 299/2023. | Country | Wage transfer deadline | Compliance level assessed at | | ------------ | ------------------------------------------------------------ | --------------------------------------- | | UAE | 1st of month (as of June 2026 for MOHRE-licensed companies) | Both company and individual level | | Saudi Arabia | Within the month, per Mudad platform requirements | Company-level (90-95% threshold) | | Oman | 3 days from end of wage entitlement period | Company-level (percentage of workforce) | | Qatar | Monthly, enforcement follows shortly after due date | Individual worker level | | Kuwait | 5th of the month (7-day outer enforcement limit) | Individual worker level | | Bahrain | Monthly file upload mandatory; payment via Fawri on approval | Company level via LMRA |

For most HR teams, 3 days is a tighter operational window than they are used to. The wage entitlement period typically ends on the last day of the month. That means payroll must be finalised, reviewed, and submitted to the bank by the 3rd of the following month at the latest, leaving no buffer for variance reviews, last-minute corrections, or bank processing delays. The SIF file needs to be ready before the period closes, not after.

There is also a contract accuracy obligation that sits alongside this deadline. Employers must update employment contracts whenever a worker's salary changes. The WPS cross-checks transfers against registered contract amounts. An outdated contract that no longer reflects an employee's actual wage creates a discrepancy in the system, which the Ministry of Labour can flag even if the payment itself is on time.

Phased Coverage Targets: What 75% and 90% Mean in Practice

Oman's Ministry of Labour rolled out WPS compliance in phases through 2025, first requiring 75% workforce coverage from September 2025 wages, then 90% from November 2025 wages. Both thresholds have now passed. The Ministry expects full private sector compliance.

• From September 2025 wages (payable October 2025): At least 75% of an establishment's total workforce must have their wages transferred through the WPS.

• From November 2025 wages (payable December 2025): The threshold rose to at least 90% of the total workforce.

• From 2026 onwards: Full universal compliance is expected across the private sector. The phased ramp has concluded.

The phased approach reflected the practical reality that many businesses in Oman were not yet integrated with digital payroll infrastructure when the system launched. It gave the Ministry of Labour a graduated enforcement mechanism to hold employers to measurable thresholds without requiring overnight adoption. That period has now closed.

For HR teams, the ramp-up period is behind you. Every employee must now be processed through WPS unless they fall within one of the five recognised exemption categories. A percentage-based tolerance is not there anymore. If an employee is outside WPS and is not covered by an exemption, that is a violation.

Exemptions: Who Falls Outside WPS Scope

Ministerial Decision No. 729/2024 explicitly defines the circumstances under which an employer is exempt from processing a salary through the WPS for a given employee. These are:

1. Labour disputes resulting in work cessation:

Where a labour dispute has caused the employee to stop working for more than 30 days, the transfer obligation is suspended for that period.

2. Suspension of work unrelated to the employer:

Where work is suspended for reasons outside the employer's control, and the suspension has lasted more than 30 days.

3. Absconding reports:

Where an absconding report has been filed and more than 30 days have elapsed since approval.

4. New joiners under 30 days:

Newly hired workers who have not yet completed 30 days of employment are outside WPS scope for their first month. Unlike Kuwait, which removed a similar exemption entirely, Oman retains this grace period for new joiners.

5. Workers on unpaid leave:

Employees on unpaid leave are excluded from the transfer obligation for the duration of that leave.

For exemptions that fall outside these five categories, employers can submit applications to a committee formed by the Ministry of Labour. This gives some flexibility for genuinely unusual situations, though the process requires formal engagement with the Ministry and is not a self-service determination.

One nuance worth noting: the exemptions apply to the specific employee and the specific period. An employee returning from unpaid leave is back within WPS scope from their first day back. An absconding case that resolves does not carry a blanket exemption forward. HR teams need to track exemption status per employee, per payroll run, with documentation supporting each case.

Enforcement: Penalties and What Triggers Them

The Ministry of Labour is empowered to enforce the WPS through an escalating sequence of penalties. The current framework under Ministerial Decision No. 729/2024 is as follows:

The OMR 50 per worker fine may appear modest compared to penalty structures in the UAE or Qatar, but the suspension of preliminary work permit services has a broader operational consequence. For businesses that rely on a steady flow of new expatriate hires, a suspended work permit service effectively pauses hiring capacity until the violation is resolved. For companies in construction, facilities management, hospitality, or any sector with high workforce turnover, that consequence carries real cost.

It is also worth noting that the Ministry's discretion in applying penalties, noted in early commentary around the system, has narrowed as enforcement has matured. With the phased targets now concluded and full compliance expected, the Ministry has moved firmly to systematic enforcement. The period of graduated, build-toward-it oversight is over.

The Contract Update Obligation: A Frequently Overlooked Requirement

One requirement in Ministerial Decision No. 729/2024 that deserves specific attention is the contract update obligation. Employers must update the employment contract whenever an employee's wage changes, and the updated contract must reflect the employee's actual wage.

This has a direct connection to WPS compliance. The system cross-checks transferred amounts against what is registered in the employment contract on record with the Ministry of Labour. Where those two figures diverge, the transfer can be flagged as a discrepancy even if the amount the employee actually received is correct. An employee who received a salary increment but whose contract was not updated creates a compliance gap that sits entirely with the employer to resolve.

For HR teams that handle pay reviews, promotions, or annual increments in batch processes, this means the contract update workflow needs to run in parallel with, not after, the payroll change. Updating the contract in the next cycle is not fast enough if the first post-increment payroll has already been processed.

HR Checklist for Oman WPS Compliance

1. Register with the WPS portal: If not already done, registration is mandatory for all private sector employers with at least one employee. It links your Commercial Registration to the Ministry of Labour's monitoring system.
2. Configure payroll cutoffs for the 3-day window: Attendance and deduction data must be finalised, and the SIF file submitted to your bank, at least one working day before the 3-day deadline to allow for bank processing time.
3. Prepare SIF files accurately: The Salary Information File must match contract-registered amounts for each employee. A single field error, including an incorrect IBAN, causes file rejection and starts the clock on a delayed transfer.
4. Update employment contracts for every salary change: Salary increments, promotions, and any other wage adjustment must be reflected in an updated contract before the next payroll cycle runs.
5. Track exemptions per employee, per month: New joiners under 30 days, employees on unpaid leave, absconding cases, and labour disputes all need to be documented individually. Blanket assumptions about exemption status create risk.
6. Ensure full WPS coverage: The phased rollout has concluded. Every employee must be processed through WPS unless they fall within a recognised exemption category. Review exemption status per employee before each payroll run
7. Retain payslips and SIF records: The Ministry of Labour can request documentation at any point. Records must be accessible for inspection without advance notice.
8. Review third-party payroll arrangements: Legal responsibility for WPS compliance stays with the employer. If a third-party provider handles payroll, confirm that SIF submissions and transfer timing meet the 3-day requirement.

FAQs

Does Oman's WPS apply to employers with fewer than five employees?

Yes. Unlike Kuwait's five-employee threshold, Oman's WPS applies to all private sector employers with at least one employee. Scope is broad, and registration is mandatory.

What exactly is the '3 days from end of wage entitlement period' deadline?

The wage entitlement period typically ends on the last day of the month. Wages must reach the employee's account within 3 days of that date, meaning the transfer must clear by the 3rd of the following month.

We gave an employee a salary increase. Do we really need to update the contract before the next payroll?

Yes. The WPS cross-checks transfers against the salary on record in the employment contract. A mismatch, even where the employee is paid correctly, can be flagged as a discrepancy.

A new employee joined on the 20th of the month. Are they within WPS scope for that month's payroll?

No. Workers who have not completed 30 days of employment are exempt from WPS for that initial period. Their first WPS-covered salary would be the following month, once 30 days of service are completed.

What does suspension of preliminary work permit services mean in practice?

The Ministry of Labour pauses the processing of new work permit applications for the company until the violation is resolved. For businesses with ongoing recruitment, this creates a direct operational hold on new hires.

Does greytHR support Oman's SIF file format?

Yes. greytHR generates Salary Information Files in the format required for Oman WPS submissions, with validation to reduce rejection risk before bank submission.

The phased rollout has concluded. Does that mean our entire workforce must now be on WPS?

Yes, with the exception of employees in a recognised exemption category. The phased targets were a ramp. That ramp has concluded and full compliance is now the standing requirement.

We use a payroll outsourcing provider. Does that affect our WPS liability?

No. Legal responsibility for timely WPS transfers stays with the employer. A third-party provider does not shift that liability, and the Ministry of Labour holds the employer accountable regardless of delegation.
