Students with past due balances for Tuition, Enrollment Fees, Housing, Meal Plans, Parking, or Book Charges may be assessed penalties for non-payment or late payment. Typically, a $40 flat fee is charged for missing a due date with additional 1.5% interest assessments each month afterwards. Those may continue until the account is placed for collections. When an account is turned to a collection agent, a servicing fee of up to 1/3 of the original charge may be added to the receivable. Additionally, in January of each year, all receivables are reported to the Oklahoma State Tax Commission. State tax returns may be captured and applied to outstanding balances. Finally, future enrollments and current records may be on hold pending payment of the balance.
