Check how payroll rounds the total CPF contribution and the employee deduction separately. They follow different rounding rules, so applying the same method to both can create a reconciliation difference even when the underlying wage inputs match.

Compare like-for-like calculations

Start with the same employee, contribution month, wage classification, age and citizenship or permanent resident status in both calculations. Save the payroll calculation detail and the CPF calculator or EZPay result. A different input requires investigation before attributing the variance to rounding.

CPF Board states that the monthly total is rounded to the nearest dollar, with 50 cents rounded up. The employee share instead has its cents dropped. Use the current official calculator or EZPay to check the complete result rather than relying on a spreadsheet's default rounding function.

Trace the difference through payroll

For example, a preparer notices that the employee deduction has been rounded upwards by the payroll spreadsheet. Review the formula, its source inputs and the approved calculation method. Do not insert a balancing deduction simply to make a report agree.

Keep a comparison showing the original calculation, checked result and reason for any correction. Ask the payroll reviewer to establish whether the issue affects the payslip, contribution submission, accounting entry or more than one record.

Correct the affected process

Preserve the original report and the reviewed replacement. Where a contribution or wage deduction has already been processed, establish the appropriate correction route before issuing revised instructions. A change to a spreadsheet does not demonstrate that an earlier payment or submission has changed.

For the next payroll cycle, test the corrected formula against the official calculation and record the review. This provides a repeatable check without treating every small difference as an acceptable rounding adjustment.
