If you see a "charge" on your account that corresponds to a refund, do not be alarmed. This is the administrative method UC San Diego uses to move a credit balance out of your student account before sending you a refund.
When payment transactions (financial aid disbursements, e-check, credit card, etc.) exceed your total charges on your account, you are left with a credit balance. To send this money to you, the system must "balance" the account by applying a line-item charge. This "charge" is simply the trigger that issues your payment via direct deposit or paper check.
You can confirm a charge is actually a refund by looking for transactions that show "Refund Issued" or "Refund Disbursement".
Note: Students who are not enrolled in direct deposit will receive their refund as a check payment to their current mailing address on file. This process typically takes 1-2 weeks. Students receiving refund checks should confirm their address is up to date in TSS.
If you still have questions, please submit a ticket.
