Oman has a well defined labour system and in the last few years the rules around employee benefits and final settlements have become more structured. When an employee leaves an organization, End of Service gratuity becomes a critical part of the exit process. Oman Labour Law clearly outlines how EOS should be calculated and paid, and it forms an important part of employee compensation and compliance.
Employers often face confusion around eligibility, salary components and calculation methods, especially when managing expatriate employees or setting up new offices in Oman.
Yomly has helped hundreds of businesses automate payroll, EOS and final settlements across the region. With our experience working closely with HR teams, we want to help further through this guide. This guide will cover how EOS gratuity works in Oman, who is eligible, how it is calculated and how employers can manage it accurately and confidently.

What Is End of Service Gratuity in Oman
Oman’s Labour Law clearly defines End of Service (EOS) gratuity as a mandatory benefit paid to eligible employees when their employment ends. The law states that EOS is meant to compensate employees for their period of service and to provide financial support at the time of exit. EOS becomes payable once the employment relationship legally comes to an end and the employee meets the minimum service requirement.
When EOS becomes payable:
- On resignation after completing the minimum service period
- On termination by the employer
- On expiry of a fixed term contract
- On mutual agreement to end employment
- On retirement, where applicable
Who EOS applies to:
EOS gratuity primarily applies to expatriate employees working in Oman. Omani nationals are covered under the social insurance system and typically do not receive EOS gratuity under Labour Law. Employers must always check the employee’s nationality and coverage status before applying the EOS rules.
Who Is Eligible for EOS in Oman?
The most confusing part for many employers is understanding who actually qualifies for End of Service gratuity. Let us make this simple and clear. Here are the categories of employees who are eligible for EOS under Oman Labour Law.
Eligible employees:
- Expatriate employees who have completed at least one full year of continuous service
- Employees working under fixed term contracts who complete their contract or exit lawfully
- Employees working under indefinite contracts who resign or are terminated in line with labour law
- Employees whose contracts end due to mutual agreement
- Employees whose employment ends due to business or operational reasons, where EOS is legally payable
Employees who complete less than one year of service are not eligible for EOS gratuity. Omani nationals are generally excluded from EOS under Labour Law because they are covered under the social insurance system.
One of the best features of يوملي is that it automatically tracks employee nationality, contract type and service duration. This ensures EOS eligibility is applied correctly every time, so you never risk overpaying or underpaying during final settlement.
Salary Components Used for EOS Calculation
Just like other GCC countries, Oman Labour Law requires employers to use specific salary components when calculating End of Service gratuity. Using the wrong components can lead to incorrect payouts and disputes. Here are the salary elements that must be considered.
Salary components included in EOS calculation:
- Basic salary as stated in the employment contract
- Fixed contractual allowances that are paid regularly and mentioned in the contract
These components together form the employee’s last drawn wage, which is used as the base for EOS calculation.
Salary components excluded from EOS calculation:
- Overtime payments
- Bonuses and incentives
- Commissions
- Performance based or variable allowances
- One time or ad hoc payments
Only amounts that are guaranteed and paid consistently are included. Any variable or irregular earnings must be excluded, even if they were paid close to the employee’s exit date.
Employers must also ensure that the most recent salary is used. If an employee received a salary revision before leaving, the updated salary must be reflected in the EOS calculation.
EOS Gratuity Formula Under Oman Labour Law
It will be better to understand End of Service gratuity in Oman by breaking down the exact formula defined under Labour Law. The calculation is straightforward, but it must be applied correctly based on the employee’s total years of service and last drawn wage.
Standard EOS Gratuity Formula
EOS is calculated based on the employee’s last basic salary plus fixed contractual allowances and the total completed years of service.
For the first three years of service:
- Employee is entitled to 15 days’ wage for each completed year
For service beyond three years:
- Employee is entitled to 30 days’ wage for each completed year after the third year
Important points to note:
- EOS is calculated only for completed years of service
- Partial years are generally calculated on a pro rata basis, depending on company policy and legal interpretation
- The wage used must be the last drawn wage, not the average or starting salary
Applying the correct formula ensures compliance and avoids disputes during final settlement. Yomly automatically applies Oman Labour Law formulas based on service duration and salary records, so employers do not need to calculate EOS manually.
EOS Calculation Examples for Oman (Step by Step)
We have shared two practical examples below to help you clearly understand how End of Service gratuity is calculated in Oman. These examples follow Oman Labour Law formulas and use realistic salary figures. Please understand that these are illustrative examples and actual payouts depend on contract terms and final salary details.
Example 1: Employee with Less Than 3 Years of Service
Employee details:
- Employment type: Expatriate
- Last drawn wage (basic + fixed allowances): OMR 600
- Total service period: 2 years
Step 1: Identify applicable formula
For the first three years, EOS is calculated at 15 days’ wage per year.
Step 2: Calculate daily wage
Monthly wage ÷ 30 = Daily wage
600 ÷ 30 = OMR 20
Step 3: Calculate EOS per year
15 days × 20 = OMR 300 per year
Step 4: Calculate total EOS
300 × 2 years = OMR 600
Final EOS payable: OMR 600
Example 2: Employee with More Than 3 Years of Service
Employee details:
- Employment type: Expatriate
- Last drawn wage: OMR 800
- Total service period: 6 years
Step 1: Calculate daily wage
800 ÷ 30 = OMR 26.67
Step 2: EOS for first 3 years
15 days × 26.67 = OMR 400 per year
400 × 3 years = OMR 1,200
Step 3: EOS for remaining 3 years
30 days × 26.67 = OMR 800 per year
800 × 3 years = OMR 2,400
Step 4: Total EOS calculation
1,200 + 2,400 = OMR 3,600
Final EOS payable: OMR 3,600
When EOS Is Reduced or Not Payable
Not every employee exit results in full End of Service gratuity in Oman. Oman Labour Law clearly defines situations where EOS may be reduced or not payable at all. Employers must understand these cases to avoid incorrect payouts and compliance issues.
EOS is not payable in the following situations:
- The employee has completed less than one year of continuous service
- The employee is dismissed for serious misconduct as defined under Oman Labour Law
- The employee is terminated due to proven violations such as fraud, theft, assault or breach of trust
- The employee causes intentional loss or serious damage to the employer and the case is legally established
EOS may be reduced in certain resignation scenarios:
- If an employee resigns before completing the required service period for full entitlement, EOS may be reduced as per applicable labour provisions and contract terms
- If the resignation violates contractual notice requirements, deductions or adjustments may apply
Employers must always review the reason for termination, service duration and legal justification before finalizing EOS. Incorrect application of reductions or denial of EOS can lead to labour disputes and penalties.
Yomly helps employers apply the correct EOS rules by linking termination reasons, service records and labour law conditions automatically, ensuring gratuity is paid accurately and only where legally required.
Common Termination Mistakes Employers Make
When we onboard a new client at Yomly, we often find the same termination and final settlement issues repeating across organizations. These mistakes usually happen due to manual processes, lack of documentation or misunderstanding of labour laws. Below are some of the most common termination mistakes employers make.
Incorrect EOS Calculation
Many employers calculate EOS using only the basic salary and ignore fixed contractual allowances. This leads to underpayment and employee disputes. In some cases, outdated salary figures are used instead of the last drawn wage, which is also non compliant.
Ignoring Service Duration Details
Employers sometimes miscalculate service duration by excluding partial years, unpaid leave periods or rejoined service. Even small errors in service calculation can significantly impact EOS and final settlement amounts.
Wrong Termination Reason Mapping
Applying the wrong termination reason can result in incorrect EOS payout. For example, treating a normal resignation as misconduct or vice versa can either wrongly reduce EOS or expose the employer to legal claims.
Delayed Final Settlement Payments
Delays in paying EOS and other dues after termination are a common issue. Labour laws require timely settlement, and delays often lead to complaints, penalties and reputational damage.
Poor Documentation and Record Keeping
Missing contracts, incomplete salary history, or lack of written warnings make it difficult to justify termination decisions. This becomes a serious problem during audits or labour disputes.
Manual Payroll and Exit Processes
Manual calculations increase the risk of human error, especially when handling multiple employees, salary structures or locations. These errors often go unnoticed until a dispute arises.
