Why is sales tax on the utility bill?

Every utility company is required to charge sales tax unless the customer files a valid exemption certificate. The utility company typically does not promote, publicize, or assist in obtaining exemptions – it is just a pass through for the utility company. The exemption is not the responsibility of the utility company rather they are only a conduit to collect tax and remit to the state.    It is the responsibility of the taxpayer to provide evidence and documentation of exemption before an account or meter is exempt.
