At the point where I'm querying about internet service, they need to know my address to ascertain that they can in fact have(/can run) a cable into my house. And when they know my address, they know all of the relevant jurisdictions imposing taxes on that and the relevant tax rates. The two things that are going to be difficult are if you want to promote, say, a nationwide "$60/month plan", or if you've got some corporate tax that's hard to calculate on a marginal basis that you're trying to pass onto consumers. Neither of those things are motivating to me. If it's too hard to compute the accurate tax fee per person, just roll that into your base plan calculation and budget accordingly. We don't expect to have to pay a corporation's corporate tax as a separate line item on the bill, so why should we expect that consumers have to pay an industry-specific corporate tax as a separate line item? At the end of the day, the reality is that this is an industry that is trying to advertise plans that are at wildly different rates from those the consumer has to pay, and they're upset that some truth-in-advertising laws is starting to be enforced. It's not even outlawing the wildly different rates; it's merely requiring transparency in the differences!
