23VAC10-115-162. Period of underpayment.
The period of the underpayment shall run from the date the installment was required to be paid to the earlier of the following dates:
1. May 1, if a calendar year, or the 15th day of the fourth month following the close of the taxable year, if a fiscal year, or
2. With respect to any portion of the underpayment, the date on which such portion is paid. For purposes of this subdivision, a payment of estimated tax on any installment date shall be considered a payment of any previous underpayment only to the extent such payment exceeds the amount of the installment determined under subdivision 1 of 23VAC10-115-161 for such installment date.
3. Example: The principles of 23VAC10-115-160, 23VAC10-115-161, and 23VAC10-115-162 may be illustrated by the following: On or before May 1, 1988, the trustee of The Jones Trust could reasonably expect the fiduciary's Virginia tax liability for calendar year 1988 to exceed $150. Therefore, the trustee timely makes four installment payments: $1,500 on May 1, 1988, and June 15, 1988, and $2,000 on September 15, 1988, and January 15, 1989. When the fiduciary income tax return is filed on May 1, 1989, the tax liability is $10,000. The total paid ($7,000) is less than 90% of the tax ($9,000). Therefore, an addition to the tax in the amount of $174.56 is due, computed as follows:
 INSTALLMENT                       1st       2nd       3rd       4th
 AMOUNT OF UNDERPAYMENT
