Late Payment and Penalties

Late Payment Charges To encourage prompt payment, a penalty is assessed for late payment. Payments must reach the University Cashier's Office by 4:00 p.m. on the due date (postmarks do not apply). If payment is not received by the due date, a late payment charge of 1.5% will be added monthly until the balance is paid in full.

Returned Checks As provided by state law, a $17.00 penalty will be assessed to the account for each check not accepted by the bank because of insufficient funds, stopped payment, nonexistent account, or any other reason for which the person is responsible. All returned checks, plus penalty, must be paid in guaranteed funds at the Cashier's Office, room 175 in the Morgan Library.
