4.2.2. For taxpayers whose estimated tax due as calculated under Section 4.2.1 of this rule is less than one thousand dollars ($1,000) in each month of a quarter, the taxpayer may elect to make a quarterly installment payment in lieu of the monthly installment, due and payable on the twentieth (20th) day of the month following the quarter in which the tax accrued.
