Illinois Statutes Chapter 50. Local Government § 355/10-35. Notification by qualified practitioner

(a) A qualified practitioner hired by a taxpayer who elects to perform a certified audit under Section 10-30 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 be submitted in the form and manner required by the Department and shall include the taxpayer's name, federal employer identification number or social security number, Department account identification number, mailing address, and 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. An engagement for a qualified practitioner to perform a certified audit under this Act shall not be authorized by the Department unless the taxpayer received notice from the Department under subparagraph (B) of paragraph (3) of subsection (c) of Section 10-30.

(b) If the taxpayer has received notice of an audit referral from the Department and 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 limit the taxes or periods subject to the certified audit.

(c) Within 30 days after receipt of the notice of qualification from the Department under subsection (b), the qualified practitioner shall contact the Department and submit, for review and agreement by the Department, a proposed audit plan and procedures. 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 if the qualified practitioner's inspection reveals that the taxpayer's circumstances or exposure to the revenue laws is substantially different from those described in the engagement notice.
