(c) For purposes of this section, there shall be four required installments for each taxable year. The first installment shall be paid on April fifteenth of the taxable year, the second on June fifteenth of the taxable year, the third on September fifteenth of the taxable year, and the fourth on January fifteenth of the succeeding taxable year. The amount of any required installment shall be twenty-five per cent of the required annual payment. The term "required annual payment" means the lesser of (i) eighty per cent, or sixty-six and two-thirds per cent in the case of a farmer or fisherman as defined in subsection (h), of the tax shown on the return for the taxable year or, if no return is filed, eighty or sixty-six and two-thirds per cent, as the case may be, of the tax for such year, or(ii) one hundred per cent of the tax shown on the return of the taxpayer for the preceding taxable year, provided the taxpayer filed a return for the preceding taxable year and such preceding year was a taxable year of twelve months. In the case of any required installment, if the taxpayer establishes that the annualized income installment is less than the amount determined under this subsection, the amount of such required installment shall be the annualized income installment, and any reduction in a required installment resulting therefrom shall be recaptured by increasing the amount of the next required installment or installments. The annualized income installment shall be based upon an estimated tax computed by placing on an annualized basis the taxable income for months in the taxable year ending before the due date for the installment.
