Non-Government Agency Filing Fee
You may be subject to a filing fee, payable to the FCC, if you are not a recognized government agency. This fee will be collected along with the original coordination fee at the time of initial screening. Applications from entities classified as associations, corporations, individuals or partnerships will be required to pay the filing fee or provide proof of their federal tax exemption status by enclosing a copy of their IRS determination letter. You can learn more about FCC fees by visiting their web site at Fee Filing Guide Page.
