20 ILCS 2510/2510-20 Notification

(20 ILCS 2510/2510-20) Sec. 2510-20. Notification. (a) A qualified practitioner shall notify the Department of an engagement to perform a certified audit and shall provide the Department with the information the Department deems necessary to identify the taxpayer, to confirm that the taxpayer is not already under audit by the Department, and to establish the basic nature of the taxpayer's business and the taxpayer's potential exposure to Illinois occupation and use tax laws. The information provided in the notification shall include the taxpayer's name, federal employer identification number or social security number, Illinois business tax number, mailing address, business location, and the specific occupation and use taxes and period proposed to be covered by the engagement for the certified audit. In addition, the notice shall include the name, address, identification number, contact person, and telephone number of the engaged firm. (b) If the taxpayer has not been issued a written notice of intent to conduct an audit, the taxpayer shall be a participating taxpayer and the Department shall so advise the qualified practitioner in writing within 10 days after receipt of the engagement notice. However, the Department may exclude a taxpayer from a certified audit or may limit the taxes or periods subject to the certified audit on the basis that the Department has previously conducted an audit, that it is in the process of conducting an investigation or other examination of the taxpayer's records, or for just cause. (c) Notice of the qualification of a taxpayer for a certified audit shall toll the statute of limitations provided with respect to the taxpayer for the tax and periods covered by the engagement. (d) Within 30 days after receipt of the notice of qualification from the Department, the qualified practitioner shall contact the Department and submit a proposed audit plan and procedures for review and agreement by the Department. The Department may extend the time for submission of the plan and procedures for reasonable cause. The qualified practitioner shall initiate action to advise the Department that amendment or modification of the plan and procedures is necessary in the event that the qualified practitioner's inspection reveals that the taxpayer's circumstances or exposure to the revenue laws is substantially different than as described in the engagement notice.

(20 ILCS 2510/2510-25) Sec. 2510-25. Audit performance and review. (a) Upon the Department's designation of the agreed-upon procedures to be followed by a practitioner in a certified audit, the qualified practitioner shall perform the engagement and shall timely submit a completed report to the Department. The report shall affirm completion of the agreed-upon procedures and shall provide any required disclosures. (b) The Department shall review the report of the certified audit and shall accept it when it is determined to be complete. Once the report is accepted by the Department, the Department shall issue a notice of proposed assessment reflecting the determination of any additional liability reflected in the report and shall provide the taxpayer with all the normal payment, protest, and appeal rights with respect to the liability, including the right to a review by the Informal Conference Board. In cases where the report indicates an overpayment has been made, the taxpayer shall submit a properly executed claim for refund to the Department. Otherwise, the certified audit report is a final and conclusive determination with respect to the tax and period covered. No additional assessment may be made by the Department for the specific taxes and period referenced in the report, except upon a showing of fraud or material misrepresentation. This determination shall not prevent the Department from collecting liabilities not covered by the report or from conducting an audit or investigation and making an assessment for additional tax, penalty, or interest for any tax or period not covered by the report.
