(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.

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.
        (5.2) Charges to entities certified under Section
    
605-1115 of the Department of Commerce and Economic Opportunity Law of the Civil Administrative Code of Illinois 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.

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.

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.

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.

Prepaid telephone calling arrangements include the recharge of a prepaid calling arrangement.
