This is to allow IRAS sufficient time to process each payment, and to prevent any potential reconciliation issues with your payments. For users with existing GIRO payment plans,please set the due date for your payments on CardUp to be 12th monthly. Note that this would be paid for the following month. Once the funds have been successfully delivered, it would take about 3-5 business days to be reflected in your tax portal as "e-payment".
Why can I only schedule a tax payment within a fixed period each month?
