(b) General Exceptions.— This section through [1] 126 of this title do not apply to—
    (1) any tax, charge, or fee levied upon or measured by the net income, capital stock, net worth, or property value of the provider of mobile telecommunications service;

(b) Jurisdiction.— All charges for mobile telecommunications services that are deemed to be provided by the customer’s home service provider under sections 116 through 126 of this title are authorized to be subjected to tax, charge, or fee by the taxing jurisdictions whose territorial limits encompass the customer’s place of primary use, regardless of where the mobile telecommunication services originate, terminate, or pass through, and no other taxing jurisdiction may impose taxes, charges, or fees on charges for such mobile telecommunications services.

### § 118. Limitations

Sections 116 through 126 of this title do not—
(1) provide authority to a taxing jurisdiction to impose a tax, charge, or fee that the laws of such jurisdiction do not authorize such jurisdiction to impose; or

### § 119. Electronic databases for nationwide standard numeric jurisdictional codes

(a) Electronic Database.—
    (1) Provision of database.— A State may provide an electronic database to a home service provider or, if a State does not provide such an electronic database to home service providers, then the designated database provider may provide an electronic database to a home service provider.
    (2) Format.—
       (A) Such electronic database, whether provided by the State or the designated database provider, shall be provided in a format approved by the American National Standards Institute’s Accredited Standards Committee X12, that, allowing for de minimis deviations, designates for each street address in the State, including to the extent practicable, any multiple postal street addresses applicable to one street location, the appropriate taxing jurisdictions, and the appropriate code for each taxing jurisdiction, for each level of taxing jurisdiction, identified by one nationwide standard numeric code.
       (B) Such electronic database shall also provide the appropriate code for each street address with respect to political subdivisions which are not taxing jurisdictions when reasonably needed to determine the proper taxing jurisdiction.
       (C) The nationwide standard numeric codes shall contain the same number of numeric digits with each digit or combination of digits referring to the same level of taxing jurisdiction throughout the United States using a format similar to FIPS 55–3 or other appropriate standard approved by the Federation of Tax Administrators and the Multistate Tax Commission, or their successors. Each address shall be provided in standard postal format.
(b) Notice; Updates.— A State or designated database provider that provides or maintains an electronic database described in subsection (a) shall provide notice of the availability of the then current electronic database, and any subsequent revisions thereof, by publication in the manner normally employed for the publication of informational tax, charge, or fee notices to taxpayers in such State.
(c) User Held Harmless.— A home service provider using the data contained in an electronic database described in subsection (a) shall be held harmless from any tax, charge, or fee liability that otherwise would be due solely as a result of any error or omission in such database provided by a State or designated database provider. The home service provider shall reflect changes made to such database during a calendar quarter not later than 30 days after the end of such calendar quarter for each State that issues notice of the availability of an electronic database reflecting such changes under subsection (b).

### § 120. Procedure if no electronic database provided

(a) Safe Harbor.— If neither a State nor designated database provider provides an electronic database under section 119, a home service provider shall be held harmless from any tax, charge, or fee liability in such State that otherwise would be due solely as a result of an assignment of a street address to an incorrect taxing jurisdiction if, subject to section 121, the home service provider employs an enhanced zip code to assign each street address to a specific taxing jurisdiction for each level of taxing jurisdiction and exercises due diligence at each level of taxing jurisdiction to ensure that each such street address is assigned to the correct taxing jurisdiction. If an enhanced zip code overlaps boundaries of taxing jurisdictions of the same level, the home service provider must designate one specific jurisdiction within such enhanced zip code for use in taxing the activity for such enhanced zip code for each level of taxing jurisdiction. Any enhanced zip code assignment changed in accordance with section 121 is deemed to be in compliance with this section. For purposes of this section, there is a rebuttable presumption that a home service provider has exercised due diligence if such home service provider demonstrates that it has—
    (1) expended reasonable resources to implement and maintain an appropriately detailed electronic database of street address assignments to taxing jurisdictions;
    (2) implemented and maintained reasonable internal controls to promptly correct misassignments of street addresses to taxing jurisdictions; and
    (3) used all reasonably obtainable and usable data pertaining to municipal annexations, incorporations, reorganizations and any other changes in jurisdictional boundaries that materially affect the accuracy of such database.
(b) Termination of Safe Harbor.— Subsection (a) applies to a home service provider that is in compliance with the requirements of subsection (a), with respect to a State for which an electronic database is not provided under section 119 until the later of—
    (1) 18 months after the nationwide standard numeric code described in section 119 (a) has been approved by the Federation of Tax Administrators and the Multistate Tax Commission; or
    (2) 6 months after such State or a designated database provider in such State provides such database as prescribed in section 119 (a).

### § 121. Correction of erroneous data for place of primary use

(a) [1] In General.—A taxing jurisdiction, or a State on behalf of any taxing jurisdiction or taxing jurisdictions within such State, may—
    (1) determine that the address used for purposes of determining the taxing jurisdictions to which taxes, charges, or fees for mobile telecommunications services are remitted does not meet the definition of place of primary use in section 124 (8) and give binding notice to the home service provider to change the place of primary use on a prospective basis from the date of notice of determination if—
       (A) if the taxing jurisdiction making such determination is not a State, such taxing jurisdiction obtains the consent of all affected taxing jurisdictions within the State before giving such notice of determination; and
       (B) before the taxing jurisdiction gives such notice of determination, the customer is given an opportunity to demonstrate in accordance with applicable State or local tax, charge, or fee administrative procedures that the address is the customer’s place of primary use;
    (2) determine that the assignment of a taxing jurisdiction by a home service provider under section 120 does not reflect the correct taxing jurisdiction and give binding notice to the home service provider to change the assignment on a prospective basis from the date of notice of determination if—
       (A) if the taxing jurisdiction making such determination is not a State, such taxing jurisdiction obtains the consent of all affected taxing jurisdictions within the State before giving such notice of determination; and
       (B) the home service provider is given an opportunity to demonstrate in accordance with applicable State or local tax, charge, or fee administrative procedures that the assignment reflects the correct taxing jurisdiction.

### § 122. Determination of place of primary use

(a) Place of Primary Use.— A home service provider shall be responsible for obtaining and maintaining the customer’s place of primary use (as defined in section 124). Subject to section 121, and if the home service provider’s reliance on information provided by its customer is in good faith, a taxing jurisdiction shall—
    (1) allow a home service provider to rely on the applicable residential or business street address supplied by the home service provider’s customer; and
    (2) not hold a home service provider liable for any additional taxes, charges, or fees based on a different determination of the place of primary use for taxes, charges, or fees that are customarily passed on to the customer as a separate itemized charge.
(b) Address Under Existing Agreements.— Except as provided in section 121, a taxing jurisdiction shall allow a home service provider to treat the address used by the home service provider for tax purposes for any customer under a service contract or agreement in effect 2 years after the date of the enactment of the Mobile Telecommunications Sourcing Act as that customer’s place of primary use for the remaining term of such service contract or agreement, excluding any extension or renewal of such service contract or agreement, for purposes of determining the taxing jurisdictions to which taxes, charges, or fees on charges for mobile telecommunications services are remitted.

### § 123. Scope; special rules

(a) Act Does Not Supersede Customer’s Liability to Taxing Jurisdiction.— Nothing in sections 116 through 126 modifies, impairs, supersedes, or authorizes the modification, impairment, or supersession of, any law allowing a taxing jurisdiction to collect a tax, charge, or fee from a customer that has failed to provide its place of primary use.
(b) Additional Taxable Charges.— If a taxing jurisdiction does not otherwise subject charges for mobile telecommunications services to taxation and if these charges are aggregated with and not separately stated from charges that are subject to taxation, then the charges for nontaxable mobile telecommunications services may be subject to taxation unless the home service provider can reasonably identify charges not subject to such tax, charge, or fee from its books and records that are kept in the regular course of business.
(c) Nontaxable Charges.— If a taxing jurisdiction does not subject charges for mobile telecommunications services to taxation, a customer may not rely upon the nontaxability of charges for mobile telecommunications services unless the customer’s home service provider separately states the charges for nontaxable mobile telecommunications services from taxable charges or the home service provider elects, after receiving a written request from the customer in the form required by the provider, to provide verifiable data based upon the home service provider’s books and records that are kept in the regular course of business that reasonably identifies the nontaxable charges.
