  such  city  or  town,  or  if  not  so provided, then as of the date the
  assessment  roll  is  completed  and  filed  prior  to  the  hearing  of
  complaints  in  connection  therewith. The date of taxable status of the
  real property contained on any assessment roll  shall  be  imprinted  or
  otherwise  indicated at the top of the first page of each volume of such
  roll.

  on any village assessment roll shall be imprinted or otherwise indicated
  at the top of the first page of each volume of such roll.
    3.  Notwithstanding  any  other  provision  of  law  to  the contrary,
  whenever any person, association  or  corporation  not  entitled  to  an
  exemption  from  taxation acquires title to property which is exempt, in
  whole or in part, from taxation,  such  property  shall  be  immediately
  subject  to  taxation  pursuant  to  section five hundred twenty of this
  chapter, except that, in cities with a  population  of  one  million  or
  more, such property shall become subject to taxation pursuant to section
  four hundred ninety-four of this chapter.
    4.  The  taxable  status of a special franchise shall be determined on
  the basis of its value and its ownership as of the first day of July  of
  the  year  preceding the year in which the assessment roll on which such
  property is to be assessed is completed and filed in the office  of  the
  city  or town clerk, except that taxable status of such properties shall
  be determined on the basis of ownership as of the first day of  July  of
  the second year preceding the date required by law for the filing of the
  final assessment roll for purposes of all village assessment rolls.
    5.  Notwithstanding  any  other provision of law to the contrary, in a
  city with a population of one million or more, whenever any  corporation
  or association entitled to exemption from taxation pursuant to paragraph
  (a) of subdivision one of section four hundred twenty-a or paragraph (a)
  of  subdivision one of section four hundred twenty-b of this chapter, or
  any local law adopted pursuant to such  provisions,  acquires  title  to
  real  property  that  is not exempt, in whole or in part, from taxation,
  such property shall, provided that it otherwise qualifies for  exemption
  pursuant  to  such  provisions, be immediately subject to exemption from
  taxation in accordance with section four hundred ninety-four-a  of  this
  chapter.
