Billing

Taxes, fees and surcharges on a telecom bill, explained

A quarter of a voice bill can be lines that are not the service. Some are taxes you owe, some are regulatory fees passed through, and some are charges the carrier made up. The bill rarely says which is which.

The quote said one number and the bill says a larger one. The difference sits in a block of lines below the service charges, and on voice and wireless services it commonly adds fifteen to thirty percent. Those lines fall into three groups: taxes set by governments, regulatory fees that the carrier pays and passes through, and surcharges the carrier created itself. Only the first group is fixed. The other two deserve a question, and the third is often negotiable.

Taxes: owed, but check the rate and the base

Federal, state and local taxes on telecom depend on the service address and the kind of service. Voice is taxed heavily, with state and local telecommunications taxes, sales tax in many places and a 911 fee per line. Internet access is different: federal law has barred state and local taxes on internet access since 2016, so a broadband or dedicated internet circuit should carry little or no tax.

Three things go wrong. The service address on the account is an old office, so the wrong city's rates apply. Taxes are calculated on the surcharges as well as the service, which inflates them. And an exempt service, such as internet access, is taxed as if it were voice. Nonprofits, schools and government bodies may also hold exemption certificates that were never filed with the carrier, and a certificate only works once the carrier has it on the account.

Regulatory fees: real, but passed through at the carrier's discretion

The largest is the Federal Universal Service Fund. The FCC sets a contribution factor every quarter as a percentage of interstate and international telecom revenue, carriers pay it, and nearly all of them pass it to customers as a line on the bill, sometimes with their own administrative markup on top. Because the percentage changes quarterly, this line moves even when nothing about your service has.

It applies to voice, SIP trunking and some private line and MPLS services. It does not apply to internet access. A universal service line on an internet-only circuit is a question for the account team, and the answer is usually a credit. State universal service and relay funds work the same way at smaller amounts.

Surcharges: the carrier's own

Lines with names like regulatory cost recovery, carrier cost recovery, property tax allocation, administrative fee or paper bill fee are not taxes. They are price, dressed in tax language, and the carrier sets them. Some are a flat amount per line and some a percentage of the bill. On business accounts a number of them can be waived, either in the contract if you ask before signing or by the account team afterward if you ask firmly.

The best time to deal with surcharges is before the order is signed. Ask for an all-in monthly estimate that names every surcharge that will apply, and ask which of them the carrier will remove.

What to do each month

  1. Split the bill into four groups: service charges, taxes, regulatory fees and carrier surcharges.
  2. Watch the share of the bill that is not service. For a stable account it should barely move. A rising share with no change in services is the signal to look closer.
  3. Ask the carrier to itemize any line over a few dollars whose name does not say what it is.
  4. On multi-site accounts, check that each line is taxed at its own service address, not the billing address.
  5. Keep exemption certificates on file and send them again whenever an account number changes or a service moves.

DemarcLabs separates taxes, fees and surcharges on every checked bill and compares their share of the charges with what is usual for that kind of service. The Tax and fee check lists the bills to question and how far above the usual range they sit.
