(35 ILCS 636/5-42)

Sec. 5-42. Procedure for determining proper tax jurisdiction.

(a) Tax jurisdiction information provided by a municipality upon written request from a telecommunications retailer. For purposes of this subsection (a), "telecommunications retailer" does not include retailers providing Commercial Mobile Radio Service as the term is used in the Mobile Telecommunications Sourcing Act.

(1) A municipality may provide, within 30 days following receipt of a written request from a telecommunications retailer, the following:

(A) A list containing each street name, known street name aliases, street address number ranges, applicable directionals, and zip codes associated with each street name, for all street addresses located within the municipality. For a range of street address numbers located within a municipality that consists only of odd or even street numbers, the list must specify whether the street numbers in the range are odd or even. The list shall be alphabetical, except that numbered streets shall be in numerical sequence.

(B) A list containing each postal zip code and all the city names associated therewith for all zip codes assigned to geographic areas located entirely within the municipality, including zip codes assigned to rural route boxes.

(C) A sequential list containing all rural route box number ranges and the city names and zip codes associated therewith, for all rural route boxes located within the municipality, except that rural route boxes with postal zip codes entirely within the municipality that are included on the list furnished under paragraph (B) need not be duplicated.

(D) The lists shall be printed. If a list is available through another medium, however, the municipality shall, upon request, furnish the list through such medium in addition to or in lieu of the printed lists. The municipality shall be responsible for updating the lists as changes occur and for furnishing this information to all telecommunications retailers affected by the changes. Each update shall specify an effective date, which shall be the next ensuing January 1, April 1, July 1, or October 1; shall be furnished to the telecommunications retailer not less than 60 days prior to the effective date; and shall identify the additions, deletions, and other changes to the preceding version of the list. If the information is received less than 60 days prior to the effective date of the change, the telecommunications retailer has until the next ensuing January 1, April 1, July 1, or October 1 to make the appropriate changes.

Nothing in this subsection (a) shall prevent a municipality from providing a telecommunications retailer with the information set forth in this subdivision (a)(1) in the absence of a written request from the telecommunications retailer.

(2) The telecommunications retailer shall be responsible for charging the tax to the service addresses contained in the lists requested under subdivision (a)(1) that include all of the elements required by this Section. If a service address is not included in the list or if no list is provided, the telecommunications retailer shall be held harmless from situsing errors provided it uses a reasonable methodology to assign the service address or addresses to a local tax jurisdiction. The telecommunications retailer shall be held harmless for any tax overpayments or underpayments (including penalty or interest) resulting from written information provided by the municipality or, in the case of disputes, the Department. If a municipality is aware of a situsing error in a telecommunications retailer's records, the municipality may file a written notification to the telecommunications retailer at an address specified by the telecommunications retailer describing the street address or addresses that are incorrect and, if known, the affected customer name or names and account number or numbers. If another jurisdiction is claiming the same street address or addresses that are the subject of the notification, the telecommunications retailer must notify the Department as specified in subdivision (a)(3) of this Section, otherwise, the telecommunications retailer shall make such correction to its records within 90 days.

(3) If it is determined from the lists or updates furnished under subdivision (a)(1) that more than one municipality claims the same address or group of addresses, the telecommunications retailer shall notify the Department within 60 days of discovering the discrepancy. After notification and until resolution, the telecommunications retailer will continue its prior tax treatment and will be held harmless for any tax, penalty, and interest in the event the prior tax treatment is wrong. Upon resolution, the Department will notify the telecommunications retailer in a written form describing the resolution. Upon receipt of the resolution, the telecommunications retailer has until the next ensuing January 1, April 1, July 1, or October 1 to make the change.

(4) Municipalities shall notify any telecommunications retailer that has previously requested a list under subdivision (a)(1) of this Section of any annexations, de-annexations, or other boundary changes at least 60 days after the effective date of such changes. The notification shall contain each street name, known street name aliases, street address number ranges, applicable directionals, and zip codes associated with each street name, for all street addresses for which a change has occurred. The notice shall be mailed to an address designated by the telecommunications retailer. The telecommunications retailer has until the next ensuing January 1, April 1, July 1, or October 1 to make the changes described in such notification.

(b) The safe harbor provisions, Sections 40 and 45 of the Mobile Telecommunications Sourcing Conformity Act, shall apply to any telecommunications retailer electing to employ enhanced zip codes (zip+4) to assign each street address, address range, rural route box, or rural route box range in their service area to a specific municipal tax jurisdiction, except as provided under subdivision (c)(5). A telecommunications retailer shall make its election as prescribed by rules adopted by the Department.

(c) Persons who believe that they are improperly being charged a tax imposed under this Act because their service address is assigned to the wrong taxing jurisdiction shall file a written complaint with their telecommunications (mobile or non-mobile) retailer. The written complaint shall include the street address for her or his place of primary use for mobile telecommunications service or the service address for non-mobile telecommunications, the name and address of the telecommunications retailer who is collecting the tax imposed by this Act, the account name and number for which the person seeks a correction of the tax assignment, a description of the error asserted by that person, an estimated amount of tax claimed to have been incorrectly paid, the time period for which that amount of tax applies, and any other information that the telecommunications retailer may reasonably require to process the request. For purposes of this Section, the terms "place of primary use" and "mobile telecommunications service" shall have the same meanings as those terms are defined in the Mobile Telecommunications Sourcing Conformity Act.

Within 60 days after receiving the complaint under this subsection (c), the telecommunications retailer shall review its records, the written complaint, any information submitted by the affected municipality or municipalities, and the electronic database, if existing, or enhanced zip code used pursuant to Section 25 or 40 of the Mobile Telecommunications Sourcing Conformity Act to determine the customer's taxing jurisdiction. If this review shows that the amount of tax, assignment of place of primary use or service address, or taxing jurisdiction is in error, the telecommunications retailer shall correct the error and refund or credit the amount of tax erroneously collected from the customer for the period still available for the filing of a claim for credit or refund by the telecommunications retailer under this Act. If this review shows that the amount of tax, assignment of place of primary use or service address, or taxing jurisdiction is correct, the telecommunications retailer shall provide a written explanation to the person from whom the notice was received.

(1) If the person is dissatisfied with the response from the telecommunications retailer, the customer may request a written determination from the Department on a form prescribed by the Department. The request shall contain the same information as was provided to the telecommunications retailer. The Department shall review the request for determination and make all reasonable efforts to determine if such person's place of primary use for mobile telecommunications service or the service address for non-mobile telecommunications is located within the jurisdictional boundaries of the municipality for which the person is being charged tax under this Act. Upon request by the Department, municipalities that have imposed a tax under this Act shall have 30 days to provide information to the Department regarding such requests for determination via certified mail.

(2) Within 90 days after receipt of a request for determination under subdivision (c)(1) of this Section, the Department shall issue a letter of determination to the person stating whether that person's place of primary use for mobile telecommunications service or the service address for non-mobile telecommunications is located within the jurisdictional boundaries of the municipality for which the person is being charged tax under this Act or naming the proper municipality, if different. The Department shall also list in the letter of determination, if the municipality has provided that information to the Department, the Department's findings as to the limit of the jurisdictional boundary (street address range) for the municipality in relation to the street address listed in the request for a letter of determination. A copy of such letter of determination shall be provided by the Department to the telecommunications retailer listed on the request for determination. The copy shall be sent via mail to an address designated by the telecommunications retailer.

(3) If the municipality or municipalities fail to respond as set forth in subdivision (c)(1), then the complaining person will no longer be subject to the tax imposed under this Act. The Department shall notify the relevant telecommunications retailer in writing of the automatic determination and also list its findings as to the street address listed in the request for a letter of determination. Upon receipt of the notice of automatic determination, the telecommunications retailer shall correct its records and refund or credit the amount of tax determined to have been paid by such person for the period still available for the filing of a claim for credit or refund by the telecommunications retailer under this Act. A copy of the letter of determination shall be provided by the Department to the telecommunications retailer listed on the request for determination at an address designated by the telecommunications retailer.

(4) If the telecommunications retailer receives a copy of the letter of determination from the Department described in subdivision (c)(2) of this Section that states that such person's place of primary use for mobile telecommunications service or the service address for non-mobile telecommunications is not located within the jurisdictional boundaries of the municipality for which that person is being charged tax under this Act and that provides the correct tax jurisdiction for the particular street address, the telecommunications retailer shall correct the error and refund or credit the amount of tax determined to have been paid in error by such person up to the period still available for the filing of a claim for credit or refund by the telecommunications retailer under this Act. The telecommunications retailer shall retain such copy of the letter of determination in its books and records and shall be held harmless for any tax, penalty, or interest due as a result of its reliance on such determination. If the Department subsequently receives information that discloses that such service addresses or places of primary use on that street are within the jurisdictional boundaries of a municipality other than the one specified in the previous letter, the Department shall notify the telecommunications retailer and the telecommunications customer in writing that the telecommunications retailer is to begin collecting tax for a specified municipality on the accounts associated with those service addresses or places of primary use. Notification to begin collecting tax on such accounts sent by the Department to the telecommunications retailers on or after October 1 and prior to January 1 shall be effective the following April 1. Notification to begin collecting tax on such accounts sent by the Department to the telecommunications retailers on or after January 1 and prior to April 1 shall be effective the following July 1. Notification to begin collecting tax on such accounts sent by the Department to the telecommunications retailers on or after April 1 and prior to July 1 shall be effective the following October 1. Notification to begin collecting tax on such accounts sent by the Department to the telecommunications retailers on or after July 1 and prior to October 1 shall be effective the following January 1.

(5) If the telecommunications retailer receives a copy of the letter of determination from the Department described in subdivisions (c)(2), (c)(3), or (c)(4) of this Section that states that such person's place of primary use for mobile telecommunications service or the service address for non-mobile telecommunications is not located within the jurisdictional boundaries of the municipality for which that person is being charged tax under this Act and the telecommunications retailer fails to correct the error and refund or credit the appropriate amount of tax paid in error within the time period prescribed in subdivisions (c)(3) and (c)(4), the telecommunications retailer shall not be held harmless for any tax, penalty, or interest due the Department as a result of the error.

(6) The procedures in this subsection (c) shall be the first course of remedy available to customers seeking correction of assignment of service address, place of primary use, taxing jurisdiction, an amount of tax paid erroneously, or other compensation for taxes, charges, or fees erroneously collected by a telecommunications retailer. No cause of action based upon a dispute arising from these taxes, charges, or fees shall accrue until a customer has reasonably exercised the rights and procedures set forth in this subsection (c). If a customer is not satisfied after exercising the rights and following the procedures set forth in this subsection (c), the customer shall have the normal cause of action available under the law to recover any tax, penalty, or interest from the telecommunications retailer.

(d) The provisions of this Section shall not apply to a municipality that directly receives collected tax revenue from a retailer pursuant to subsection (b) of Section 5-40. A municipality that receives tax revenue pursuant to subsection (b) of Section 5-40 for telecommunications other than mobile telecommunications service, as that term is defined in the Mobile Telecommunications Sourcing Conformity Act, shall establish a procedure to remedy the complaints of persons who believe they are being improperly taxed, which should consider the requirements set forth in subsection (c) of this Section.
