Some of these fees are, indeed, paid to the government. That does not mean they are a tax, in the same sense that (as mentioned elsewhere) a building permit is not a tax, but is still required by, and paid to, the government.
I'm not trying to excuse Verizon for not including them in their overall pricing, but these two in particular:
- Fed Universal Service Charge
- Regulatory Charge
are both paid to the government, and variable based on usage.
Edit: I will also note that Verizon has a $3.50 per-line fixed line item called "Admin & Telco Recovery Charge" that is utter BS.
