(35 ILCS 630/2) (from Ch. 120, par. 2002)
    Sec. 2. As used in this Article, unless the context clearly requires otherwise:
    (a) "Gross charge" means the amount paid for the act or privilege of originating or receiving telecommunications in this State and for all services and equipment provided in connection therewith by a retailer, valued in money whether paid in money or otherwise, including cash, credits, services and property of every kind or nature, and shall be determined without any deduction on account of the cost of such telecommunications, the cost of materials used, labor or service costs or any other expense whatsoever. In case credit is extended, the amount thereof shall be included only as and when paid. "Gross charges" for private line service shall include charges imposed at each channel termination point within this State, charges for the channel mileage between each channel termination point within this State, and charges for that portion of the interstate inter-office channel provided within Illinois. Charges for that portion of the interstate inter-office channel provided in Illinois shall be determined by the retailer as follows: (i) for interstate inter-office channels having 2 channel termination points, only one of which is in Illinois, 50% of the total charge imposed; or (ii) for interstate inter-office channels having more than 2 channel termination points, one or more of which are in Illinois, an amount equal to the total charge multiplied by a fraction, the numerator of which is the number of channel termination points within Illinois and the denominator of which is the total number of channel termination points. Prior to January 1, 2004, any method consistent with this paragraph or other method that reasonably apportions the total charges for interstate inter-office channels among the states in which channel terminations points are located shall be accepted as a reasonable method to determine the charges for that portion of the interstate inter-office channel provided within Illinois for that period. However, "gross charges" shall not include any of the following:
        (1) Any amounts added to a purchaser's bill because of a charge made pursuant to (i) the
    
tax imposed by this Article; (ii) charges added to customers' bills pursuant to the provisions of Sections 9-221 or 9-222 of the Public Utilities Act, as amended, or any similar charges added to customers' bills by retailers who are not subject to rate regulation by the Illinois Commerce Commission for the purpose of recovering any of the tax liabilities or other amounts specified in such provisions of such Act; (iii) the tax imposed by Section 4251 of the Internal Revenue Code; (iv) 911 surcharges; or (v) the tax imposed by the Simplified Municipal Telecommunications Tax Act.
        (2) Charges for a sent collect telecommunication received outside of the State.
        (3) Charges for leased time on equipment or charges for the storage of data or
    
information for subsequent retrieval or the processing of data or information intended to change its form or content. Such equipment includes, but is not limited to, the use of calculators, computers, data processing equipment, tabulating equipment or accounting equipment and also includes the usage of computers under a time-sharing agreement.
        (4) Charges for customer equipment, including such equipment that is leased or rented by
    
the customer from any source, wherein such charges are disaggregated and separately identified from other charges.
        (5) Charges to business enterprises certified under Section 9-222.1 of the Public
    
Utilities Act, as amended, or under Section 95 of the Reimagining Energy and Vehicles in Illinois Act, to the extent of such exemption and during the period of time specified by the Department of Commerce and Economic Opportunity.
        (5.1) Charges to business enterprises certified under the Manufacturing Illinois Chips
    
for Real Opportunity (MICRO) Act, to the extent of the exemption and during the period of time specified by the Department of Commerce and Economic Opportunity.
        (6) Charges for telecommunications and all services and equipment provided in connection
    
therewith between a parent corporation and its wholly owned subsidiaries or between wholly owned subsidiaries when the tax imposed under this Article has already been paid to a retailer and only to the extent that the charges between the parent corporation and wholly owned subsidiaries or between wholly owned subsidiaries represent expense allocation between the corporations and not the generation of profit for the corporation rendering such service.
        (7) Bad debts. Bad debt means any portion of a debt that is related to a sale at retail
    
for which gross charges are not otherwise deductible or excludable that has become worthless or uncollectable, as determined under applicable federal income tax standards. If the portion of the debt deemed to be bad is subsequently paid, the retailer shall report and pay the tax on that portion during the reporting period in which the payment is made.
        (8) Charges paid by inserting coins in coin-operated telecommunication devices.
        (9) Amounts paid by telecommunications retailers under the Telecommunications Municipal
    
Infrastructure Maintenance Fee Act.
        (10) Charges for nontaxable services or telecommunications if (i) those charges are
    
aggregated with other charges for telecommunications that are taxable, (ii) those charges are not separately stated on the customer bill or invoice, and (iii) the retailer can reasonably identify the nontaxable charges on the retailer's books and records kept in the regular course of business. If the nontaxable charges cannot reasonably be identified, the gross charge from the sale of both taxable and nontaxable services or telecommunications billed on a combined basis shall be attributed to the taxable services or telecommunications. The burden of proving nontaxable charges shall be on the retailer of the telecommunications.
    (b) "Amount paid" means the amount charged to the taxpayer's service address in this State regardless of where such amount is billed or paid.
    (c) "Telecommunications", in addition to the meaning ordinarily and popularly ascribed to it, includes, without limitation, messages or information transmitted through use of local, toll and wide area telephone service; private line services; channel services; telegraph services; teletypewriter; computer exchange services; cellular mobile telecommunications service; specialized mobile radio; stationary two way radio; paging service; or any other form of mobile and portable one-way or two-way communications; or any other transmission of messages or information by electronic or similar means, between or among points by wire, cable, fiber-optics, laser, microwave, radio, satellite or similar facilities.

The definition of "telecommunications" shall not include value added services in which computer processing applications are used to act on the form, content, code and protocol of the information for purposes other than transmission. "Telecommunications" shall not include purchases of telecommunications by a telecommunications service provider for use as a component part of the service provided by him to the ultimate retail consumer who originates or terminates the taxable end-to-end communications. Carrier access charges, right of access charges, charges for use of inter-company facilities, and all telecommunications resold in the subsequent provision of, used as a component of, or integrated into end-to-end telecommunications service shall be non-taxable as sales for resale.

    (l) "Retailer" means and includes every person engaged in the business of making sales at retail as defined in this Article. The Department may, in its discretion, upon application, authorize the collection of the tax hereby imposed by any retailer not maintaining a place of business within this State, who, to the satisfaction of the Department, furnishes adequate security to insure collection and payment of the tax. Such retailer shall be issued, without charge, a permit to collect such tax. When so authorized, it shall be the duty of such retailer to collect the tax upon all of the gross charges for telecommunications in this State in the same manner and subject to the same requirements as a retailer maintaining a place of business within this State. The permit may be revoked by the Department at its discretion.

For air-to-ground systems and the like, service address shall mean the location of a taxpayer's primary use of the telecommunications equipment as defined by telephone number, authorization code, or location in Illinois where bills are sent.
    (o) "Prepaid telephone calling arrangements" mean the right to exclusively purchase telephone or telecommunications services that must be paid for in advance and enable the origination of one or more intrastate, interstate, or international telephone calls or other telecommunications using an access number, an authorization code, or both, whether manually or electronically dialed, for which payment to a retailer must be made in advance, provided that, unless recharged, no further service is provided once that prepaid amount of service has been consumed. Prepaid telephone calling arrangements include the recharge of a prepaid calling arrangement. For purposes of this subsection, "recharge" means the purchase of additional prepaid telephone or telecommunications services whether or not the purchaser acquires a different access number or authorization code. "Prepaid telephone calling arrangement" does not include an arrangement whereby a customer purchases a payment card and pursuant to which the service provider reflects the amount of such purchase as a credit on an invoice issued to that customer under an existing subscription plan.
