An employee resigns with a payout for unused leave. Payroll processes it the same way it processed every bonus that year, using the estimate set back in January. Weeks later, the CPF Board flags a shortfall, because the actual Ordinary Wages (OW) paid never matched the estimate used to calculate the ceiling.
CPF contribution rates in 2026 are clear on paper. Leave pay gets miscalculated anyway, because the errors sit in the mechanics, not the rate.
Here are 6 mistakes employers still make with CPF on leave pay, and how to fix each one.
How Is Leave Pay Classified Under CPF?
Leave pay is classified as Additional Wage (AW) under CPF, not Ordinary Wages (OW).
- OW is the employee’s regular monthly salary, capped at a monthly ceiling.
- AW covers payments made at intervals of more than a month, including bonuses, incentive payments, and leave pay such as encashed or unused leave.
- The distinction matters because AW is subject to its own annual ceiling, separate from the monthly OW ceiling, and both feed into the CPF contribution rates in 2026.
Payroll teams managing this alongside other CPF contribution requirements and broader Singapore payroll compliance obligations often treat leave pay as an afterthought instead of a distinct wage category.
Mistake 1: Using Actual Salary Instead of Capped OW in the AW Formula
The AW Ceiling is $102,000 minus the OW subject to CPF for the year. OW subject to CPF is capped at $8,000 a month in 2026, so salary above that cap never counts.
Take an employee aged 55 or below who earns $9,000 a month.
- OW subject to CPF is $8,000 x 12, which equals $96,000.
- The AW Ceiling is $102,000 minus $96,000, which equals $6,000.
- On a $20,000 leave payout, only $6,000 attracts CPF.
- CPF on that $6,000 is $2,220 (17% employer, 20% employee).
Now the error. Payroll plugs in the actual $9,000 salary, so yearly OW becomes $108,000. The AW Ceiling falls to zero, and no CPF is paid on the payout.
That leaves a $2,220 shortfall on one resignation. It usually surfaces only when the AW Ceiling is recalculated or CPF Board reviews the account, and late payment interest can apply.The fix is simple. Cap OW at $8,000 a month before running the AW formula, for every employee at or above the cap.
Mistake 2: Treating the AW Ceiling as Company-Wide
The AW Ceiling applies per employer per year, not per employee across their career or per company as a whole.
- An employee who changes jobs mid-year gets a separate, full AW Ceiling with the new employer.
- Payroll teams sometimes assume a shared or prorated ceiling applies across employers, which is incorrect.
- This mistake usually shows up when HR carries over an assumption from a previous payroll system without checking CPF’s actual rule.
Getting this wrong either overpays or underpays CPF on a leave payout for any employee who joined partway through the year.
Mistake 3: Skipping Recalculation at Resignation or Year-End
The AW Ceiling is estimated at the start of the year using expected monthly OW, then recalculated using actual OW paid at resignation, salary change, or year-end.
- The January estimate rarely matches the actual OW paid across the full year.
- Any shortfall from the recalculation must be paid in December, or in the employee’s last month if they resign earlier.
- Skipping this recalculation step is what created the shortfall in the opening example.
Payroll reviews tied to Singapore payroll compliance mistakes that trigger MOM audits consistently flag this recalculation gap.
Mistake 4: Late Reporting of No-Pay Leave Status Changes
A no-pay leave period changes the OW actually paid for that month, which affects both the OW ceiling used and any AW Ceiling recalculation tied to it.
- Payroll needs to be notified of no-pay leave promptly, not after the pay run has already processed.
- A delayed update means the system calculates CPF against a salary figure that no longer reflects what was actually paid.
- This compounds with any leave-payout timing issue in the same period, since both affect the same OW base.
Mistake 5 & 6: Not Claiming Refunds, and Assuming the AW Ceiling Rises With OW
Two smaller errors tend to appear together, both from not tracking the AW Ceiling closely enough.
- Over-contributed CPF on a leave payout, caused by any of the errors above, is refundable through an application with the CPF Board, but most employers never claim it back.
- The AW Ceiling itself stays fixed at $102,000 even as the OW ceiling rises under the updated CPF contribution rates in 2026, including the increase to $8,000.
- Assuming the AW Ceiling moves in step with the OW ceiling leads to miscalculated leave-payout contributions every year the OW ceiling changes.
Employers should treat the AW Ceiling as a separate, fixed figure to check annually, not one that adjusts automatically alongside other CPF changes in Singapore.
CPF on Leave Pay: Correct vs Incorrect Handling
A side-by-side view makes these errors easier to catch during a payroll review.
| Mistake | Incorrect handling | Correct handling |
| OW figure used | Actual salary above the cap | Capped OW ceiling |
| Ceiling scope | Treated as company-wide | Calculated per employer per year |
| Recalculation | Skipped after January estimate | Done at resignation, salary change, or year-end |
| No-pay leave | Reported late to payroll | Reported before the pay run processes |
| Overpaid CPF | Left unclaimed | Refunded via CPF Board application |
| AW Ceiling vs OW ceiling | Assumed to move together | Tracked as separate, fixed figures |
How Procloz Supports CPF Compliance on Leave Pay
Managed payroll operations remove the manual tracking that causes most of these errors. Rather than relying on a January estimate carried through the full year, an outsourced payroll model recalculates the AW Ceiling at resignation, salary change, and year-end as standard practice.
This means the OW ceiling, not actual salary, is used in every AW calculation, no-pay leave updates reach payroll before the next pay run, and over-contributed CPF gets flagged for refund rather than left unclaimed.
Procloz supports this as an operational partner managing payroll execution for businesses in Singapore, including through EOR services for employers without a local entity, reducing the chance a leave payout gets miscalculated before anyone notices.

Frequently Asked Questions about CPF Contribution Rates in 2026
Q: Is leave pay treated as Ordinary Wages or Additional Wages under CPF?
A: Leave pay is treated as Additional Wage (AW), not Ordinary Wages. This means it is subject to the separate annual AW Ceiling rather than the monthly OW ceiling.
Q: How is the AW Ceiling calculated for a leave payout?
A: The AW Ceiling equals $102,000 minus the OW ceiling subject to CPF for the year, not the employee’s actual salary. Using actual salary above the cap overstates CPF owed on the payout.
Q: Does the AW Ceiling apply across an employee’s whole career?
A: No. The AW Ceiling applies per employer per year. An employee who changes jobs mid-year gets a full, separate AW Ceiling with the new employer.
Q: What happens if too much CPF is paid on a leave payout?
A: Over-contributed CPF can be refunded through an application with the CPF Board. Many employers never claim this refund, leaving the overpayment unresolved.
Q: Do the CPF contribution rates in 2026 change the AW Ceiling?
A: No. The AW Ceiling stays fixed at $102,000 even as the OW ceiling rises under the 2026 rates to $8,000. The two figures must be tracked separately.
