within the Department or pursuant to official procedures for collection
of any State tax or pursuant to an investigation or audit by the Illinois
State Scholarship Commission of a delinquent student loan or monetary award
or enforcement of any civil or criminal penalty or sanction
imposed by this Act or by another statute imposing a State tax, and any
person who divulges any such information in any manner, except for such
purposes and pursuant to order of the Director or in accordance with a proper
judicial order, shall be guilty of a Class A misdemeanor.   However, the
provisions of this paragraph are not applicable to   information furnished
to (i) the Department of Healthcare and Family Services (formerly
Department of Public Aid), State's Attorneys, and the Attorney General for child support enforcement purposes and (ii) a licensed attorney representing the taxpayer where an appeal or a protest

The furnishing upon request of the Auditor General, or his or her authorized agents, for official use of returns filed and information related thereto under this Act is deemed to be an official purpose within the Department within the meaning of this Section.

(b) Public information. Nothing contained in this Act shall prevent
the Director from publishing or making available to the public the names

Secretary of the Treasury of the United States or his delegate, or the
proper officer or his delegate of any other state imposing a tax upon or
measured by income, for exclusively official purposes, information received

shall be granted only if the United States or such other state, as the case
may be, grants the Department substantially similar privileges.  The Director
may exchange information with the Department of Healthcare and Family Services and the
Department of Human Services (acting as successor to the Department of Public
Aid under the Department of Human Services Act) for

incorporation by the Secretary of State has failed to file returns under
