§ 1513. Declarations of estimated tax. (a) Requirements of
declaration.--Every taxpayer subject to the taxes imposed under this
article shall make a declaration of its estimated tax for the current
taxable year, containing such information as the commissioner of
taxation and finance may prescribe by regulations or instructions, if
such estimated tax can reasonably be expected to exceed one thousand
dollars. If a taxpayer is subject to the tax surcharge imposed by
section fifteen hundred five-a and such taxpayer's estimated tax under
this article can (without regard to section fifteen hundred five-a
thereof) reasonably be expected to exceed one thousand dollars, such
taxpayer shall also make a declaration of its estimated tax surcharge
for the current taxable year.

(b) Definition of estimated tax and estimated tax surcharge. The terms
"estimated tax" and "estimated tax surcharge" mean the amounts which the
taxpayer estimates to be the taxes imposed by sections fifteen hundred
one, fifteen hundred two-a and fifteen hundred ten of this article or
the tax surcharge imposed by section fifteen hundred five-a of this
article, respectively, for the current taxable year, less the sum of any
credits which it estimates to be allowable against such taxes or tax
surcharge, respectively.

(c) Time of filing declaration.--A declaration of estimated tax and a
declaration of estimated tax surcharge shall be filed on or before June
fifteenth of the current taxable year in the case of a taxpayer which
reports on the basis of a calendar year, except that if the requirements
of subdivision (a) of this section are first met:

(1) after May thirty-first and before September first of such current
taxable year the declaration shall be filed on or before September
fifteenth, or

(2) after August thirty-first and before December first of such
current taxable year, the declaration shall be filed on or before
December fifteenth.

(d) Amendments of declaration.--A taxpayer may amend a declaration of
estimated tax or a declaration of estimated tax surcharge under
regulations prescribed by the commissioner of taxation and finance.

(e) Return as declaration. If, on or before February fifteenth of the
succeeding year in the case of a taxpayer whose taxable year is a
calendar year, a taxpayer files its return for the year for which the
declaration is required, and pays therewith the balance, if any, of the
full amount of the tax or tax surcharge shown to be due on the return

(1) such return shall be considered as its declaration if no
declaration was required to be filed during the taxable year for which
the tax or tax surcharge was imposed, but is otherwise required to be
filed on or before December fifteenth pursuant to paragraph two of
subdivision (c) of this section, and

(2) such return shall be considered as the amendment permitted by
subdivision (d) of this section to be filed on or before December
fifteenth if the tax or tax surcharge shown on the return is greater
than the estimated tax or estimated tax surcharge, as the case may be,
shown on a declaration previously made.

(f) Short taxable period. If the taxable period for which a tax or tax
surcharge is imposed under this article is less than twelve months,
every taxpayer required to make a declaration of estimated tax or a
declaration of estimated tax surcharge for such taxable period shall
make such declaration in accordance with rules of the commissioner of
taxation and finance.

(g) Fiscal year. The provisions of this section shall apply to taxable
years of twelve months other than a calendar year by the substitution of
the months of such fiscal year for the corresponding months specified in
such provisions.

(h) Extension of time. The tax commission may grant a reasonable
extension of time, not to exceed three months, for the filing of any
declaration required pursuant to this section, on such terms and
conditions as it may require.
