When is the due date to submit CPF contributions?

The due date for CPF contributions is on the last day of the calendar month. Enforcement action would be taken if CPF contributions are not paid by the 14^th of the following month (or the next working day if the 14^th falls on a Saturday, Sunday or Public Holiday). This includes imposing late payment interest charged at 1.5% per month commencing from the first day after the due date.
