Estimate only — not a Form 499, an invoice, or legal advice. Safe harbors are from the FCC Form 499-A instructions (VoIP 64.9%, wireless 37.1%). The contribution factor is the one USAC lists for the quarter in effect (Q4 2026, 42.0%). It updates when USAC posts the next quarter and that quarter begins. Circularity is not applied. Under the FCC rule, a filer is generally de minimis when the year’s contribution is under $10,000.
