  where  his  or  her  base  rent  is not in excess of twenty-five hundred
  dollars per year or where his or her base rent is for a period  of  less
  than  one  year  and  would not exceed twenty-five hundred dollars for a

    For  tax  years  embraced  within  the  period  beginning  after   May
  thirty-first,    nineteen   hundred   seventy-seven   and   ending   May
  thirty-first, nineteen hundred eighty, the tax shall be imposed at rates
  equal to ninety percent of the rates shown in the foregoing table.
    For tax years  beginning  after  May  thirty-first,  nineteen  hundred
  eighty and ending May thirty-first, nineteen hundred eighty-one, the tax
  shall  be  imposed  at  rates  equal to eighty-five percent of the rates
  shown in the foregoing table.
    For tax years  beginning  after  May  thirty-first,  nineteen  hundred
  eighty-one, the tax shall be imposed at rates equal to eighty percent of
  the rates shown in the foregoing table.
    Where  the  rent is for a period of less than one year, the rate shall
  be determined by assuming that the rent is on an  equivalent  basis  for
  the entire year.
    b.    Nothing  contained  in  this  chapter shall be deemed to require
  payment of a double or multiple tax pursuant to this chapter on any part
  of any taxable premises.
    c.  Where a tenant pays an undivided rent for premises used  both  for
  residential   purposes  and  as  taxable  premises,  the  tax  shall  be
  applicable to so much of the rent as is ascribable  to  the  portion  of
  such  premises  used  as  taxable  premises.    Where, however, the rent
  ascribable to so much of such premises as is used  as  taxable  premises
  does  not exceed fifty dollars a month, such rent shall be excluded from
  such tenant's base rent.  Nothing contained in this subdivision shall be
  construed as indicating an intent to exclude any base rent from the  tax
  imposed  by  this  chapter  merely  because  it  is  paid  as part of an
  undivided rent for premises which are only  partially  used  as  taxable
  premises.
    d.    The  tax imposed by this chapter shall be in addition to any and
  all other taxes including the public housing tax imposed by chapter  ten
  of this title.
    e.  Nothing contained in this section shall be construed as permitting
  base  rent  of  a  tenant  for  one  taxable  premises  to be reduced by

  deducting rents received by him or her for another taxable  premises  of
  which he or she is also a tenant.
