Managing employee wages in Singapore involves understanding the distinction between Ordinary Wages (OW) and Additional Wages (AW). This classification is crucial for accurate payroll processing, CPF contributions, and tax compliance. In this guide, we break down the key differences, calculation methods, and employer obligations related to OW and AW.

What Are Ordinary Wages (OW)?

Ordinary Wages (OW) refer to the monthly wages earned by an employee for work performed within the same month. These are subject to CPF contributions and are capped based on the CPF Wage Ceiling.

Examples of Ordinary Wages:

  • Monthly basic salary
  • Fixed allowances (e.g., transport, meal, or shift allowances)
  • Overtime pay (if paid within the same month and within the OW ceiling)

CPF Contributions and Ordinary Wages (OW) Ceiling:

CPF contributions for OW are calculated based on the employee’s monthly salary. In the Singapore Budget 2023, the CPF Ordinary Wages Ceiling will increase in stages from $6,000 to $8,000 by 2026. Here is the timeline of the increases:

CPF Monthly Salary Ceiling

CPF Annual Salary Ceiling

Before 1st September 2023

S$6,000

S$102,000

From 1st September 2023

S$6,300

From 1st January 2024

S$6,800

From 1st January 2025

S$7,400

From 1st January 2026

S$8,000

Overtime Pay Scenarios:

If an employee works overtime during this month and is paid by the 14th of the following month, it will be considered an Ordinary Wage (OW). Otherwise, it will be considered an Additional Wage (AW).
Overtime Period Payable Date for Overtime Pay Wage Classification CPF Payable By
1-30 June 10 July OW for June 14 July
1-30 June 31 July AW for July 14 August

What Are Additional Wages (AW)?

Additional Wages (AW) refer to payments made to employees that are not part of their fixed monthly salary. These payments are usually variable and may be given periodically rather than monthly.

Examples of Additional Wages:

  • Annual bonuses
  • Commissions (if paid at irregular intervals)
  • Incentive payments
  • Leave encashment
  • Retrenchment benefits

CPF Ceiling for Additional Wages (AW):

Example 1: Employee earns less than $6,000 of Ordinary Wage (OW)

Jessie is 42 years old and earns a $4,500 monthly salary. She will be receiving a total Additional Wage (AW) of $100,000 in 2025.  As mentioned by the Minister of Finance, $102,000 is the total Ordinary Wages subjected to CPF for the year. Additional Wage (AW) Ceiling = $102,000 - (Monthly wage x 12) = $102,000 - ($4,500 x 12) = $48,000

Month in Year 2025

OW paid ($) OW subject to CPF ($) CPF payable on OW (Employer) ($) CPF payable on OW (Employee) ($) AW paid ($) AW subject to CPF ($) CPF payable on AW (Employer) ($)

CPF payable on AW (Employee) ($)

Total 54,000 54,000 9,180 10,800 100,000 48,000 8,160 9,600
The maximum AW that is subject to CPF in 2025 would be $48,000. Thus, the remaining AW of $52,000 would not be subject to CPF, if Jessie works till the end of the year.

Example 2: Employee earns more than $7,400 of Ordinary Wage (OW)

Nicholas is 45 years old and earns a $8,000 monthly salary. He will be receiving a total Additional Wage (AW) of $100,000 in 2025.  As mentioned by the Minister of Finance, $102,000 is the total Ordinary Wages subjected to CPF for the year. Additional Wage (AW) Ceiling = $102,000 - (CPF Ceiling in 2025 x 12) = $102,000 - ($7,400 x 12) = $13,200

The maximum AW that is subject to CPF in 2025 would be $28,800. Thus, the remaining AW of $71,200 would not be subject to CPF, if Nicholas works till the end of the year.

Payments Not Considered Wages (No CPF Contributions)

Some payments made to employees are not classified as wages and are therefore not subject to CPF contributions. Here are common examples:
  • Termination or Retrenchment Benefits: Compensation provided upon employment termination is not considered wages since it is not payment for services rendered.
  • Expense Reimbursements: Payments made to employees for work-related expenses are not subject to CPF, provided they do not exceed the actual amount spent. Examples include:
    • Entertainment expenses incurred while hosting clients on behalf of the company.
    • Training and examination fees covered as part of an employee’s professional development.
    • Meal expenses for employees working beyond regular hours.
  • Benefits-in-Kind: Non-monetary perks such as company-provided housing, transport, or gifts are not considered wages.
  • Flexible Benefits: Medical or dental expense reimbursements for employees and their dependents (spouse and child) are also exempt from CPF contributions.
