After completing your income tax payment via CardUp, you can verify its status through the myTax Portal.
Please allow 3-5 business days after the payment due date for your IRAS account to be updated with the payment information:
Log in to myTax Portal and select "View Details" or download your Statement of Account.
Your payment should appear as an “e-payment” within 3–5 business days after the due date, which is when CardUp transfers the funds to IRAS.
A brief verification period may occur before the payment reflects in your account—this is normal and ensures accuracy.
Below is a screenshot example of how the payment made through CardUp will appear on your IRAS statement:
Following these steps will help you confirm that IRAS has successfully received your payment.
