Carriers, your FCC Annual Regulatory Fees must be paid via the FCC’s Fee Filer system by Thursday, September 24, 2015. The 25% late-payment fee should incent timely payment. Note that if you would otherwise owe less than $500, you are considered de minimis, and no fee is due.
The ITSP – for Interstate Telecommunications Service Provider – Regulatory Fee Fact Sheet is here. Wireless carriers can find their Regulatory Fee Fact Sheet here. All other licensees (e.g., cable TV, international, satellite) can check their details here.
