Section 15. Report of change in federal or New York state taxable income

If
  the amount of a taxpayer's federal or New York state taxable  income  or
  self-employment  income  reported  on  his federal or New York state tax
  return for any taxable year is changed or corrected by the United States
  internal revenue service or the New York state commissioner of  taxation
  and  finance  or  other  competent  authority,  or  as  the  result of a
  renegotiation of a contract or subcontract with the United States or New
  York state or if a taxpayer, pursuant to subsection (d) of  section  six
  thousand  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  of  waiver  of  the
  restrictions  provided  in subsection (c) of said section, or if any tax
  on self-employment income in addition to that shown  on  his  return  is
  assessed, the taxpayer shall report such change or correction in federal
  or  New  York  state  taxable income or such execution of such notice of
  waiver or such assessment and the changes or corrections of his  federal
  or  New  York state taxable income or self-employment 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 the making of such assessment as otherwise required by  the
  commissioner,  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 or self-employment income tax  return  shall  also
  file  within  ninety  days thereafter an amended return under this local
  law, and shall give such information as the  commissioner  may  require.
  The  commissioner  may  by  regulation  prescribe such exceptions to the
  requirements of this  section  as  he  or  she  deems  appropriate.  For
  purposes  of  this  section,  (i)  the  term  "taxpayer" shall include a
  partnership having any income derived from city sources,  and  (ii)  the
  term  "federal  income  tax  return" shall include the returns of income
  required under section six thousand thirty-one of the  internal  revenue
  code.  Reports  made  under this section by a partnership shall indicate
  the portion of the  change  in  each  item  of  income,  gain,  loss  or
  deduction allocable to each partner and shall set forth such identifying
  information  with  respect  to  such partner as may be prescribed by the
  commissioner.
