Nothing in this section shall be construed to prohibit:  (1) The disclosure of information, returns, reports, or facts shown thereby, as described in subsection 1 of this section, by any officer, clerk or other employee of the department of revenue charged with the custody of such information:  (a) To a taxpayer or the taxpayer's duly authorized representative under regulations which the director of revenue may prescribe;  (b) In any action or proceeding, civil, criminal or mixed, brought to enforce the revenue laws of this state;  (c) To the state auditor or the auditor's duly authorized employees as required by subsection 4 of this section;  (d) To any city officer designated by ordinance of a city within this state to collect a city earnings tax, upon written request of such officer, which request states that the request is made for the purpose of determining or enforcing compliance with such city earnings tax ordinance and provided that such information disclosed shall be limited to that sufficient to identify the taxpayer, and further provided that in no event shall any information be disclosed that will result in the department of revenue being denied such information by the United States or any other state. The city officer requesting the identity of taxpayers filing state returns but not paying city earnings tax shall furnish to the director of revenue a list of taxpayers paying such earnings tax, and the director shall compare the list submitted with the director's records and return to such city official the name and address of any taxpayer who is a resident of such city who has filed a state tax return but who does not appear on the list furnished by such city.
