(A)  Fifteen percent of the rental paid shall be deducted for heat, or
heat and gas;
  (B) Twenty percent of the rental paid shall be deducted for heat,  gas
and electricity;
  (C) Twenty-five percent of the rental paid shall be deducted for heat,
gas, electricity and furnishings;
  (D)  Fifty percent of the rental paid shall be deducted for heat, gas,

  4. The attorney general shall prepare and submit to  the  commissioner
of  internal  revenue  of  the United States a request for a ruling that
payments of real property taxes made by a renter  in  such  municipality
with  an  interest  in real property pursuant to subdivision two of this
section, with respect to such  interest,  will  be  deductible  by  such
renter pursuant to paragraph a of subdivision one of section one hundred
sixty  four of the internal revenue code of nineteen hundred fifty-four,
as amended.
  5. Immediately after the effective date of  this  section  and  on  or
before  the  tax  status  date  of  the ensuing fiscal year and annually
thereafter,  the  owner  of  the  real  property  shall  file  with  the
appropriate  assessment department of the municipality in which the real
property is located the rent roll covering all units of  said  property,
including  names  of  those  renters  whose  interest  is  described  in
subdivision two of this section and those renters who  have  elected  an
interest as described in subdivision four of this section. This schedule
of  rents  shall  include  all  units whether rented or not, and whether
residential or not.  The assessors shall assign an assessed valuation to
each rental unit of said real property by establishing the  relationship
of  the  yearly  rent  for  the  unit  to the total yearly rent roll and
applying this ratio to the assessment established for the real  property
as  a  whole,  less  the assessment on that portion of the real property
which the assessor may determine is not held for rental purposes.  Taxes
on  such  real  property  not held for rental purposes shall be assessed
solely against  the  owner  of  the  real  property  and  shall  not  be
considered  in  determining  the assessed valuation of each rental unit.
Where the residential real property is completed  after  the  first  tax
status  day  after the effective date of this section, the owner of such
real property shall file the required  information  with  the  assessors
after  completion.  In  the  event  the  assessors  reassess  said  real
property, the relationships established for the prior assessments  shall
be applied to the new assessments. The assessments so established may be
entered  on  the  assessment  roll itself or attached as an appendage to
such assessment roll but in any event  the  assessments  for  said  real
property  shall be deemed a composite of the total of the assessments of
each individual unit's assessment, and those renters whose  interest  is
described  in subdivision two of this section and those renters who have
elected an interest as described in subdivision  four  of  this  section
shall  be  personally  liable  for  the  taxes levied on the assessments
declared for their respective units. It shall be the  responsibility  of
the owner of the real property to notify the assessors of all changes in
occupancy  including  notification  when a vacant unit is occupied or an
occupied unit becomes vacant. The assessors on or before tax status  day
will issue in writing to the owner a listing of the assessments assessed
for  each unit. This listing shall state the amount of taxes each renter
whose interest is described in subdivision two of this section and  each
renter  who  has elected an interest as described in subdivision four of
this section must pay each calendar month of the assessing unit's fiscal
year. The landlord shall make this listing available to each tenant upon
occupancy  and  thereafter  upon  receipt  of  such  listing  from   the
assessors.
