Notice and timing
How delinquency is handled
Grace period after the due date
Payment is due according to the bill; the FY2026 fee schedule describes a $10 late penalty when payment is not received by close of business on the due date, the 15th day from the billing date, or the mailing date. This establishes the late-trigger rule but not a separate grace period after the printed due date.
Late-fee calculation
The FY2026 schedule lists a $10 late penalty per late payment, assessed if payment is not received by close of business on the due date, the 15th day from the billing or mailing date. It also lists a $25 delinquent-account fee per delinquency, separate from the late penalty, and $75 for an illegal turn-on and $100 for an illegal jumper.
Disconnection timeline
The reviewed Killeen pages do not expose an exact day-by-day calendar from the missed bill to physical shutoff. The City’s residential application says delinquency notifications are sent by phone, text, and email, while the fee schedule supplies the late-trigger date and delinquent-account fee but not the final disconnect day.
