Three things are certain: death, taxes, and the FCC regulatory fee schedule. (The last two happen annually; the first one, hopefully not.) The fees, due September 25, represent your Share of the $113 million collected from regulated media, which in turn contributes to the $322 million FCC 2018 budget. The fees range from $500 (AM Class C stations serving fewer than 25,000 people) to $18,800 (several FM Classes).
