September 28 Credit Card Payment: When Do You Need to Have Money in Your Account? A Late Same-Day Deposit May Not Be Debited
If your credit card payment was due during the 2026 Chuseok holiday, from September 24 to 27, it will generally be automatically debited from your designated payment account on September 28 without late fees.
However, depositing money on September 28 does not guarantee that the payment will be successfully debited. Withdrawal processing times and retry procedures vary depending on the card issuer and the financial institution holding the payment account. The safest approach is to ensure that your account has a balance at least equal to the billed amount before September 28.
What Time Will Credit Card Payments Be Debited on September 28?
Not all credit card payments will be debited at the same time on September 28.
Card issuers submit debit requests to the designated payment accounts, and banks process those requests. As a result, actual withdrawal times may differ depending on the card issuer and financial institution.
Particular caution is needed when depositing funds late on the payment due date. BC Card advises that funds deposited after 16, the financial institution's business closing time, may not be debited that day depending on the institution's circumstances, potentially resulting in a late payment.
SC First Bank's credit card usage guidance also specifies different deposit deadlines depending on the type of payment account.
Therefore, you should not assume that depositing money anytime before midnight on September 28 will always be sufficient.
The Safest Approach Is to Have Sufficient Funds Available by September 27
If you know how much will be charged to your account on September 28, the simplest approach is to deposit the required amount into your payment account by the previous day rather than trying to time the withdrawal on the payment date itself.
For example, if your credit card bill is KRW 1,200,000, you should check whether other automatic payments are scheduled for the same day instead of maintaining a balance of exactly KRW 1,200,000.
Automatic payments for insurance premiums, telecommunications charges, utility bills, and similar expenses originally due from September 24 to 27 are also generally postponed to September 28. However, payments subject to separate agreements may be debited on a different business day.
In other words, if you prepare only for your credit card bill on September 28, another automatic payment could be processed first, leaving insufficient funds when the credit card payment is due to be debited.
Is It Okay to Deposit Money on the Morning of September 28?
Some payments may be successfully debited after funds are deposited on the due date. However, it is difficult to establish a single deposit deadline that applies to every card issuer and bank.
Payment methods also differ among card issuers. KB Kookmin Card has separate operating hours and processing rules for its immediate debit payment and virtual account payment services.
Therefore, if you discover that your account has insufficient funds on September 28, it is better to check your payment status through your card issuer's app rather than simply depositing money and waiting.
If the automatic debit attempt has already been completed, you can check alternative payment methods offered by your card issuer, such as immediate payment, direct debit payment, or virtual account payment.
What Should You Do If a Payment Was Not Debited Because of Insufficient Funds?
First, check the outstanding amount and current payment status through your card issuer's app or website.
Depending on the card issuer, another automatic debit attempt may be made, or a separate immediate payment option may be available. However, the procedures and processing times are not the same for every issuer.
In particular, if you make a separate payment through a virtual account or immediate payment service on the due date while also leaving money in your original payment account, there is a possibility of a duplicate debit.
BC Card advises that paying through a virtual account or similar method on the due date may result in a duplicate debit from the designated payment account. In such cases, the company explains that the duplicated amount will be refunded on the next business day.
Therefore, if you confirm that a payment has not been debited, it is advisable to proceed in the following order.
1. Check whether the payment has been completed in your card issuer's app.
2. Check whether any outstanding balance remains.
3. Review the available payment methods, such as immediate payment or direct debit payment, and their operating hours as specified by your card issuer.
4. If you have paid separately, also check whether any additional debit has been made from your original payment account.
Check Other Automatic Payments Alongside Your Credit Card Bill on September 28
The 2026 Chuseok holiday runs from September 24 through 27. The Financial Services Commission announced that due dates for credit card bills, utility bills, and similar payments falling within this period would be postponed to September 28.
As a result, more withdrawals than usual may be concentrated on September 28.
When reviewing your scheduled payments, it is advisable to check not only your credit card bill but also insurance premiums, telecommunications charges, utility bills, and other automatic payments postponed because of the holiday.
In conclusion, the safest approach for credit card payments due on September 28 is to ensure that sufficient funds are available in your designated payment account in advance rather than depositing money late on the due date. If you discover insufficient funds on the payment date, check the payment status and availability of immediate payment options in your card issuer's app, as debit and retry procedures vary among issuers.
