  If  the  amount of a taxpayer's federal or New York state taxable income
  reported on his or her federal or New York  state  income  tax  for  any
  taxable  year  is  changed  or  corrected  by the United States internal
  revenue service or the New York state tax commission or other  competent
  authority,  or  as  the  result  of  a  renegotiation  of  a contract or
  subcontract with the United States or the state of New  York,  or  if  a
  taxpayer,  pursuant  to  subsection  (d)  of  section  sixty-two hundred
  thirteen of the internal revenue code, executes a notice  of  waiver  of
  the  restrictions  provided  in  subsection (a) of said section, or if a
  taxpayer, pursuant to subsection (f) of section six  hundred  eighty-one
  of the tax law, executes a notice or waiver of the restrictions provided
  in  subsection  (c)  of  such section of the tax law, the taxpayer shall
  report such change or correction in federal or New  York  state  taxable
  income  or  such  execution  of such notice of waiver and the changes or
  corrections of the taxpayer's federal or New York state  taxable  income
  on  which  it is based, within ninety days after the final determination
  of such change, correction, or renegotiation, or such execution of  such
  notice  of  waiver,  or  as  otherwise  required  by the commissioner of
  finance, and shall concede the accuracy of such determination  or  state
  wherein  it  is erroneous. Any taxpayer filing an amended federal or New
  York state  income  tax  return  shall  also  file  within  ninety  days
  thereafter  an  amended  return  under this chapter, and shall give such
  information as the commissioner of finance may require. The commissioner
  of  finance  may  by  regulation  prescribe  such  exceptions   to   the
  requirements of this section as the commissioner deems appropriate.
