(b) (1) The provisions concerning returns under section fifteen

except that for purposes of an automatic extension for six months for
filing a return covering the taxes imposed by this article, such
automatic extension shall be allowed, for taxable years to which the tax

in addition to any other amounts required under this article, two and
one-half percent, fifteen percent, ten percent, five percent or zero
percent, whichever is the rate applicable to the taxable year pursuant
to subdivision (a) of this section, of the amount properly estimated as

against tax otherwise allowable under section fifteen hundred eleven of
this article in the case of the tax surcharge imposed at the rate of two

five or zero percent. The tax surcharge imposed by this section shall be
payable to the commissioner in full at the time the return is required
to be filed.

(2) Except as otherwise provided in this section, all of the
provisions of this article, except for sections fifteen hundred five,
fifteen hundred five-A and fifteen hundred eleven, presently applicable
are applicable to the tax surcharge imposed by this section with such
modifications as may be necessary to adapt such language to the tax
surcharge imposed by this section. Such provisions shall apply with the
same force and effect as if those provisions had been set forth in full
in this section except to the extent that any provision is either
inconsistent with a provision of this section or not relevant to the tax
surcharge imposed by this section and to that end a reference in this
article to the tax imposed by sections fifteen hundred one and fifteen
hundred ten of this article shall be read as a reference to the tax
surcharge imposed by this section, and to the sum of such tax and such
tax surcharge in the case of sections fifteen hundred thirteen and
fifteen hundred fourteen of this article and such other provisions
requiring such reading in order to effectuate the purposes of this
provision, unless a different meaning is clearly required.

(c) Coordination with section fifteen hundred five-A of this article.
The amount of tax surcharge imposed pursuant to this section shall not
be included in any calculation of a tax surcharge imposed pursuant to
section fifteen hundred five-A of this article.

(d) Insofar as subdivision (a) of this section establishes a rate of
fifteen percent in the case of taxable years ending after June
thirtieth, nineteen hundred ninety and before July first, nineteen
hundred ninety-four and until such rate is superseded, a rate of ten
percent in the case of taxable years ending after June thirtieth,
nineteen hundred ninety-four and before July first, nineteen hundred
ninety-five and until such rate is superseded, a rate of five percent in
the case of taxable years ending after June thirtieth, nineteen hundred
ninety-five and before July first, nineteen hundred ninety-six and until
such rate is superseded, and a rate of zero percent in the case of
taxable years ending after June thirtieth, nineteen hundred ninety-six
and before July first, nineteen hundred ninety-seven, the transition
from such rate of fifteen percent to such rate of ten percent, from such
rate of ten percent to such rate of five percent, and from such rate of
five percent to such rate of zero percent, shall be deemed to occur,
respectively, on the first day of the seventh month of each of such
taxable years, with the result that for purposes of implementation of
such changes in rates, and notwithstanding such subdivision (a), there
is hereby imposed with respect to all taxable years ending after June
thirtieth, nineteen hundred ninety-four and before July first, nineteen
hundred ninety-five, including taxable years of fewer than twelve
months, a tax surcharge at the rate of twelve and one-half percent;
there is hereby imposed with respect to all taxable years ending after
June thirtieth, nineteen hundred ninety-five and before July first,
nineteen hundred ninety-six, including taxable years of fewer than
twelve months, a tax surcharge at the rate of seven and one-half
percent; and there is hereby imposed with respect to all taxable years
ending after June thirtieth, nineteen hundred ninety-six and before July
first, nineteen hundred ninety-seven, including taxable years of fewer
than twelve months, a tax surcharge at the rate of two and one-half
percent. In addition, for purposes of implementation of all the
provisions of this section references to ten percent shall be read as
references to twelve and one-half percent, references to five percent
shall be read as references to seven and one-half percent and references
to zero percent shall be read as references to two and one-half percent.
