Interest shall be imposed per annum, on all unpaid income tax, unpaid estimated income tax and unpaid withholding tax.

The interest rate used shall be the Federal short-term rate (rounded to the nearest whole number percent) plus five percent. The rate shall apply for the calendar year next following the July of the year in which the Federal short-term rate is determined.

Note: Interest applies to any balance of tax due that is not paid by the due date of a return, even if the return is filed under extension.
