Central Provident Fund (CPF) payroll calculations are where most Singapore SME payroll errors originate. The rates change with employee age, apply differently to ordinary wages and additional wages, and have a monthly ceiling that affects higher-salary employees. Our team has reviewed payroll audits where the CPF error was not a rounding mistake but a wrong rate bracket used for an employee who turned 55 during the year. The rate change on the birthday month is the most common missed update in manual payroll systems. Automated payroll software handles this without any manual intervention. Manual systems do not.
Key Takeaways
- CPF rates vary by employee age in four brackets: Below 55, 55 to 60, 60 to 65, and above 65. The combined employer-employee rate drops from 37% to 12.5% across these brackets (Source: CPF Board)
- Ordinary Wages (OW) and Additional Wages (AW) have different CPF ceilings: OW CPF applies up to SGD 6,800 per month. AW CPF applies to the remaining annual CPF contribution limit after OW contributions are accounted for.
- The employer must pay both shares: The employer pays the employer’s share and deducts the employee’s share from the salary. Failing to pay either share is an offence under the CPF Act.
- CPF must be paid by the 14th of the following month: Late CPF payment attracts late payment interest of 1.5% per month (Source: CPF Board).
- Payroll software automates rate changes at age milestones: When an employee crosses an age bracket threshold, software updates the rate automatically. Manual systems require a manual rate change that is frequently missed.
CPF Contribution Rates by Age Bracket
CPF contribution rates are set by the CPF Board and updated periodically. The rates below are based on the published 2026 guidance. Always verify current rates at the CPF Board website before processing payroll.
| Employee Age | Employer Rate | Employee Rate | Total |
|---|---|---|---|
| 55 and below | 17% | 20% | 37% |
| Above 55 to 60 | 15% | 16% | 31% |
| Above 60 to 65 | 11.5% | 10.5% | 22% |
| Above 65 to 70 | 9% | 7.5% | 16.5% |
| Above 70 | 7.5% | 5% | 12.5% |

These rates apply to Singapore Citizens and Permanent Residents (with graduated rates for first and second year PRs). They do not apply to Employment Pass or S Pass holders.
Ordinary Wages vs Additional Wages
Ordinary Wages (OW) are wages due or granted wholly in respect of an employee’s employment in the month. This includes basic salary, fixed allowances, and commissions paid monthly. Additional Wages (AW) are wages not granted wholly in respect of the month, such as annual bonuses, year-end payments, and performance bonuses.
The CPF ceiling for Ordinary Wages is SGD 6,800 per month (from 2026). CPF is calculated on OW up to this ceiling only. Salary above SGD 6,800 per month does not attract CPF on the excess OW.
For Additional Wages, the CPF applies up to the AW ceiling, which is calculated as:
AW CPF ceiling = SGD 102,000 minus total OW on which CPF was paid in that calendar year.
An employee earning SGD 6,800 per month for 12 months has paid CPF on SGD 81,600 OW. Their AW ceiling is SGD 102,000 minus SGD 81,600 = SGD 20,400. A year-end bonus above SGD 20,400 does not attract CPF on the excess.
The Birthday Month Rate Change
When an employee crosses an age bracket threshold, their CPF rate changes from the month of their birthday. This is the most common CPF calculation error in manual payroll systems.
For an employee turning 56 in March:
- January and February payroll: rates for “55 and below” apply
- March payroll onwards: rates for “above 55 to 60” apply
In a manual payroll system, someone must update the rate in the spreadsheet or system in March. In payroll software, the birthday date in the employee profile triggers the rate change automatically.
For HR payroll software Singapore, this automation is the single most compliance-valuable feature for any Singapore employer with employees near CPF age thresholds.
“The birthday month rate change is not a rare edge case. Every company with employees over 50 has this calculation to get right every year.”
CPF Payment Deadlines and Late Payment Consequences
CPF contributions must be paid by the 14th of the month following the salary month. For salary paid in January, CPF must be paid by 14 February. Employers who pay CPF after the deadline are charged late payment interest (Source: CPF Board).
Late payment consequences:
- Late payment interest: 1.5% per month on the outstanding amount
- Prosecution for persistent non-payment under the CPF Act
- Employees can report non-payment to the CPF Board directly
Most cloud payroll systems generate the CPF payment file automatically and can schedule submission to the CPF Board’s e-Submit portal, removing the manual deadline tracking.
Frequently Asked Questions
Do Employment Pass holders need CPF deductions in Singapore?
No. CPF contributions apply to Singapore Citizens and Permanent Residents only. Employment Pass (EP) holders, S Pass holders, and other work visa categories are not subject to CPF deductions. Their payroll calculation is simpler: gross salary minus income tax withholding (if applicable), with no CPF component.
What is the CPF contribution rate for a new Permanent Resident in Singapore?
New Permanent Residents have graduated CPF rates for the first two years of PR status. In the first year, the employer contributes 4% and the employee 5%. In the second year, the rates increase. From the third year, full CPF rates apply. Verify the current graduated rates at the CPF Board website (Source: CPF Board).
How do I calculate CPF for an employee who resigns mid-month?
CPF is calculated on actual wages earned. For a mid-month resignation, calculate the pro-rated salary for days worked, then apply the CPF rate to that amount. The OW ceiling applies pro-rated only if the employee’s pro-rated salary for the partial month exceeds SGD 6,800, which is unlikely.
What happens if I overpay CPF in Singapore?
Overpaid CPF can be refunded by applying to the CPF Board. The refund process requires the submission of supporting documents showing the overpayment. Payroll software with CPF calculation validation can prevent most overpayments by checking the calculation before submission.
Is CPF required for part-time employees in Singapore?
Yes, CPF contributions are required for part-time employees who are Singapore Citizens or PRs earning more than SGD 50 per month. The same rates and age brackets apply. The contribution is calculated on actual wages paid, not a full-time equivalent.
Conclusion
CPF payroll calculations in Singapore require accurate rate brackets by age, correct treatment of ordinary and additional wages, and timely payment by the 14th of each month. The birthday month rate change is the most common manual error. Payroll software eliminates this by tracking employee ages and updating rates automatically. For any Singapore employer with more than five employees, the compliance risk of manual CPF calculation outweighs the cost of payroll software.
