§  1307.  Change  of  resident  status.  (a) General. If an individual changes his status during his taxable year from city  resident  to  city nonresident,  or  from  city nonresident to city resident, he shall file one return as a city resident for the portion of the year  during  which he is a city resident, and a return under a local law for the portion of the  year  during  which  he  is  a  city  nonresident,  subject to such exceptions as the state tax commission may prescribe by regulation. Such return shall be due at the same time as the return for  the  portion  of the year during which such individual is a city resident.  (b)  The  city taxable income for the portion of the year during which an individual described in subsection (a) is a city resident  individual shall  be  determined,  except  as provided in subsection (c), under the rules provided in section six hundred thirty-eight of this  chapter,  as if  he  were  computing his New York taxable income and his taxable year for New York state personal income tax  purposes  were  limited  to  the period of his city resident status.  (c)  When  an individual changes his status from city resident to city nonresident, or from  city  nonresident  to  city  resident,  he  shall, regardless  of  his  method  of  accounting, accrue any items of income, gain,  loss,  deduction  or  ordinary  income  portion  of  a  lump  sum distribution accruing prior to the change of status, with the applicable modifications  and  adjustments  to  federal  adjusted  gross income and itemized deductions under sections six hundred twelve  and  six  hundred fifteen,  if not otherwise properly includible or allowable for New York income tax purposes for such period or a prior taxable  year  under  his method of accounting. Such accruals shall be made as provided in section six hundred thirty-nine of this chapter.  (d)  Trusts.  If the status of a trust changes during its taxable year from city resident to city nonresident, or from city nonresident to city resident, the fiduciary shall file one return as a city  resident  trust for  the  portion  of the year during which the trust is a city resident trust, and a return under a local law for the portion of the year during which the trust is a city nonresident trust, subject to such  exceptions as the state tax commission may prescribe by regulations.  (e) The city taxable income for the portion of the year during which a trust  described  in  subsection  (d)  is a city resident trust shall be determined, except as  provided  in  subsection  (c),  under  the  rules provided  in section six hundred thirty-eight of this chapter, as if its New York taxable income were being computed and its taxable year for New York state personal income tax purposes were limited to  the  period  of its city resident status.  (f)  When  the  status  of  a trust changes from city resident to city nonresident, or from  city  nonresident  to  city  resident,  it  shall, regardless  of  its  method  of  accounting, accrue any items of income, gain, loss or deduction accruing prior to the  change  of  status.  Such accruals shall be made as provided in section six hundred thirty-nine of this chapter.
