   (c)   The refusal to produce books, papers, records and federal income tax returns, or the refusal to submit to such examination, by any employer or person subject or presumed to be subject to the tax or required to withhold tax, or the failure of any person to comply with the provisions of this section or with an order or subpoena of the Income Tax Supervisor authorized hereby, shall be deemed a violation of this chapter.
 
   (d)   Any information gained as a result of any returns, investigations, verifications or hearings before the Income Tax Supervisor, required by this chapter or authorized by these rules and regulations, shall be confidential and no disclosure thereof shall be made except for official purposes or as ordered by a court of competent jurisdiction.
 
   (e)   Every taxpayer shall retain all records necessary to compute his tax liability for a period of five years from the date his return is filed or the withholding taxes are paid.
