CPF submission, and what being late costs.

Ask most employers when CPF is due and the answer is the 14th. That is the enforcement date: CPF Board takes action if contributions are not paid by the 14th of the following month, or the next working day where the 14th falls on a weekend or public holiday. The due date itself is earlier, and it is the last day of the contribution month.

The distinction is not academic, because interest accrues from the day after the due date rather than from the 14th. The Board’s own worked example makes it plain: October contributions, due on 31 October and paid on 20 November, are charged as nineteen days late, not six. An employer who treats the 14th as a free grace period is accruing interest for a fortnight without knowing it.

The ladder above is what the CPF Act provides for; none of it is triggered by anything more exotic than a submission going in after month end. Running the monthly cycle on time, reconciling it, and catching a shortfall before interest starts accruing is what Payroll Processing covers for Singapore employers. If you would rather keep it in-house, the due date and the interest rule above are the two facts that actually decide whether it goes wrong.

Every employer submits under a CPF Submission Number, which pairs the entity’s UEN with a payment code. One point worth knowing before you apply: a separate CSN is needed for each type of payment, so mandatory contributions, voluntary contributions and MediSave contributions under the Additional MediSave Contribution Scheme each have their own. The payment mode is a later choice, and the Board currently lists two: Direct Debit and PayNow QR.

Submission itself runs through CPF EZPay, which needs the employer’s own corporate login and the CSN, with a mobile version the Board suggests for ten employees or fewer. Contributions are payable for Singapore Citizens and Permanent Residents earning more than S$50 a month; between S$50 and S$500 the employer pays its share and nothing is deducted from the employee; foreigners, including Employment Pass and S Pass holders, are outside the scheme entirely.

That is the shape of it rather than the whole of it. The Board publishes a standing list of the errors it sees most, from bonuses wrongly capped at the Ordinary Wage ceiling to overtime pay misclassified between Ordinary and Additional Wages, and each of them is found in a payroll run rather than in a guide. Running the cycle so those do not happen is the service.
