(b) To determine the amount of each tax credit allowed for the taxable year to be used, refunded or credited as an overpayment the taxpayer shall multiply the amount of each credit subject to deferral that would have been used, refunded or credited as an overpayment in the absence of this section by a fraction, the numerator of which is two million dollars, and the denominator of which is the total amount of the taxpayer's credits subject to deferral pursuant to subdivision three of this section that would have been used, refunded or credited as an overpayment for the taxable year in the absence of this section. The product is the amount of such credit that is not subject to deferral and thus allowed to be used, refunded or credited as an overpayment for the taxable year. 2. Taxpayers shall calculate and make any estimated tax payments required to be made by taking into account the deferral of credits required by this section. Taxpayers shall calculate any mandatory first installment payments made on or after the effective date of this section as if the deferral of credits required by this section had been in effect for the taxable year upon which that installment is based. In addition, for taxable years beginning on or after January first, two thousand ten and before January first, two thousand eleven, (a) no addition to tax under subsection (c) of section six hundred eighty-five of this chapter or subsection (c) of section one thousand eighty-five of this chapter shall be imposed with respect to any underpayment attributable to the deferral required by this section of any estimated taxes that are required to be paid prior to the enactment of this section, provided that the taxpayer timely made those payments; and (b) the required installment of estimated tax described in clause (ii) of subparagraph (B) of paragraph three of subsection (c) of section six hundred eighty-five of this chapter, and the exception to addition for underpayment of estimated tax described in paragraph one or two of subsection (d) of section one thousand eighty-five of this chapter, in relation to the preceding year's return, shall be calculated as if the deferral required by this section had been in effect for that entire preceding year. 3.
