    63-3046A.  INTEREST ON UNDERPAYMENT OF ESTIMATED TAX. (a) In the event
that a person required to pay estimated taxes under section 63-3036A, Idaho
Code, fails to pay such estimated taxes or fails to pay the full amount of
estimated taxes due, the state tax commission shall assess interest on such
unpaid or underpaid estimated taxes at the rate of interest set in section
63-3045, Idaho Code, as the interest to be assessed on a deficiency in taxes.
    (b)  Interest shall be computed on the difference between the amount of
estimated payment required to be made on each quarterly report and the amount
of quarterly payment actually made. Interest shall apply from the due date of
the quarterly report until the required amount is paid, or until, excluding
extensions, the due date of the return, whichever is first.
