32 V.S.A. § 9782: Mobile telecommunications sourcing

(a) Mobile telecommunications services shall be sourced according to the provisions of the federal Mobile Telecommunications Sourcing Act, 4 U.S.C. §§ 116-126. The definitions and provisions of such Act are hereby incorporated into this section by reference.

(b)(1) If charges for nontaxable mobile telecommunications service are aggregated with and not separately stated from charges for taxable service, then all charges are subject to taxation, unless the home service provider can reasonably identify nontaxable charges from its books and records kept in the regular course of business. If the home service provider can reasonably identify from its books and records that are kept in the regular course of business the portion of the aggregated charge that is attributable to nontaxable service, only the charges for taxable services are subject to taxation.

(2) A customer may not rely upon the nontaxability of mobile telecommunications services unless the customer’s home service provider separately states the charges for nontaxable mobile telecommunications services or the home service provider elects pursuant to 4 U.S.C. § 123(c) to provide verifiable data required to support the nontaxability.
