• (4) In the case of taxpayers having a fiscal year beginning in a calendar year with a rate in effect that is different than the rate in effect for the next calendar year and ending in the next calendar year, the tax due for that taxable year shall be determined by:
  • (a) Computing for the full fiscal year the amount of tax that would be due under the rates in effect for the calendar year in which the fiscal year begins; and
  • (b) Computing for the full fiscal year the amount of tax that would be due under the rates in effect for the calendar year in which the fiscal year ends; and

  • (d) Applying to the tax computed under paragraph (b) the ratio which the number of months falling within the later calendar year bears to the total number of months within the fiscal year; and
  • (e) Adding to the tax determined under paragraph (c) the tax determined under paragraph (d) the sum of which shall be the amount of tax due for the fiscal year.
