The FCC Form 499-A is an annual revenue reporting obligation for providers of interstate telecommunications services in the United States, including interconnected VoIP providers. The 2026 form covers calendar year 2025 revenue and was due on April 1, 2026. If you provide voice services to US customers or route traffic over US networks, this filing likely applies to you — and getting it right has implications beyond the filing itself.
Who must file
The Form 499-A obligation applies to providers of interstate telecommunications services and interconnected VoIP services. This includes carriers, resellers, and wholesalers who derive revenue from providing voice services that cross state lines or that interconnect with the public switched telephone network. Providers whose total annual revenues from these services exceed certain thresholds must file. The FCC's USAC database maintains a public list of all registered filers.
Operating through a foreign entity does not automatically exempt a provider from US filing obligations if the provider is offering services to US customers or routing traffic through US networks. Infinititel Pty Ltd holds its own FCC registration (Filer ID 836943) in addition to Infinititel LLC (Filer ID 836996), reflecting the reach of these obligations for internationally-operating carriers.
Why the business description matters
The Form 499-A asks filers to describe their business and the services they provide. For wholesale carriers — providers whose customers are other carriers, resellers, and businesses rather than end users — the business description should accurately reflect that wholesale-only nature. A description that reads as retail activity can trigger attention from state telecommunications tax administrators who use FCC filings as a reference when identifying providers potentially subject to state-level surcharges.
Several states have sent tax notices to FCC-registered providers based on the assumption that registration implies retail activity in their jurisdiction. A clear, accurate business description that specifies wholesale-only operations, with no end-user customers, provides a defensible basis for responding to those notices.
FUSF contributions and reseller certificates
The Form 499-A is the basis for calculating a provider's Federal Universal Service Fund contribution obligation. Providers report their revenue from telecommunications services, and USAC uses that revenue as the basis for assessing contributions to the USF programs administered by the FCC.
Providers who purchase services for resale — rather than as end users — may hold a FUSF reseller certificate from their upstream supplier. This certificate is a representation that the purchaser is buying services for resale, which means the upstream supplier does not collect USF contributions from them on the basis that the reseller will contribute directly. Holding a reseller certificate creates an obligation to ensure your own 499-A accurately reflects the revenue base subject to contribution. Infinititel holds a reseller certificate from Hypercube Networks / 46 Labs for its US interconnect arrangements.
State tax notice strategy
State telecommunications tax notices are a common experience for FCC-registered providers, particularly those with a wholesale-only business model. States may send notices based on the fact of FCC registration, without any specific knowledge that the provider has customers or activity in their jurisdiction.
The appropriate response to such a notice is not to ignore it — that creates a risk of default assessment — but also not to assume it creates a legitimate tax liability. The response should set out clearly that the provider's business is wholesale-only, that it has no end-user customers in the state, and provide supporting documentation including a copy of the FCC registration and the business description filed on the 499-A. Most states will close the inquiry on this basis once they have confirmed there is no retail activity in their jurisdiction.
Filing mechanics and deadlines
The Form 499-A covers the prior calendar year and is due on April 1 each year. Late filing can result in FCC enforcement action and USAC assessment penalties. Amendments are permitted but create a public audit trail, so it is better to file accurately on time than to file provisionally and amend later. USAC provides an online filing system, and providers must maintain current registration details in the FCC's CORES system.
Providers with multiple entities operating in the US — such as a foreign parent and a US subsidiary — should review whether each entity independently has a 499-A obligation and file accordingly. Treating a single consolidated filing as sufficient when two separate entities have independent obligations is a compliance risk.
What changes year to year
The FCC periodically adjusts the Form 499-A instructions, revenue categories, and contribution methodology. Before filing each year, review the current instructions rather than relying on prior-year workflows. The USAC website publishes updated instructions and filing guides ahead of each filing period. The FCC also issues public notices and advisories regarding significant changes to the filing requirements.
