E-Rate invoice deadlines and the 15-day extension window

Reviewed September 6, 2026 · E-Rate Wave · Check official records and current guidance before acting.

USAC’s current rules allow one automatic 120-day extension per FRN when requested before the invoice deadline or within 15 days afterward. An expired date is a reason to investigate immediately.

Which date controls?

Check 120 days after the last service date, the FCDL, or an eligible revised FCDL, using the latest applicable date. If the first denial or reduction notice for a timely invoice arrives on or after the deadline, a conditional 60-day period allows a corrected invoice.

How to request an extension

• Before the deadline: use EPC’s invoice deadline extension request and check FRN eligibility.
• Within 15 days afterward: open an EPC Customer Service Case listing the FRNs; this is USAC’s interim route.
• Beyond that window: USAC needs an FCC waiver grant before extending the deadline. Relief is not automatic.

Check prior extensions and the exact record against USAC’s current instructions.

Turn a missed date into a review task

For a consulting firm, the operational question is which client needs attention and what evidence to inspect. E-Rate Wave combines deadline views with published invoice detail, authorized amounts, and CSV export. A remaining balance is not proof that the money can be invoiced or recovered.
