(A) In case of any underpayment of the estimated tax provided under section 5733.021 of the Revised Code, there shall be added to the tax for the tax year an amount determined at the rate per annum prescribed by section 5703.47 of the Revised Code upon the amount of underpayment for the period of underpayment.
(B) The amount of the underpayment shall be the excess of:
(1) The amount of the estimated tax payment which would be required to be paid if the total estimated tax were equal to the total tax shown to be due on the report required to be filed, or if no report was filed, the tax for such year, over
(2) The amount, if any, of the estimated tax paid on or before the last day prescribed for such payment.
(C) The period of the underpayment shall run from the date the estimated tax payment was required to be made to the date on which such payment is made. For purposes of this section, a payment of estimated tax on any payment date shall be considered a payment of any previous underpayment only to the extent such payment exceeds the amount of the payment presently due.
