This subrule is effective for tax years beginning on or after January 1, 1984.
EXAMPLE: Corporation X filed its 1994 return on April 20, 1995, showing an overpayment of $400 and a credit to 1995 estimated tax of $400. During processing of the return, it was determined that 50 percent of the federal income tax refund received was subtracted from net income instead of being added to net income. Correction of this error resulted in an overpayment of $200 instead of $400. Thus, the amount credited to the taxpayer's estimated payments for 1995 was $200 instead of the $400 shown on the return form. The department notified Corporation X of the error and advised that only $200 was being credited to the taxpayer's estimated tax for 1995 instead of the $400 shown on the return.
EXAMPLE: Corporation X filed its original September 30, 1995, return on January 15, 1996, with an overpayment of $500 and all of the overpayment credited to its estimated tax for the tax year ending September 30, 1996. Later, in 1996, X determined that it had failed to claim a deduction on the return for depreciation on some business equipment it acquired in tax year ended September 30, 1995. Therefore, X filed an amended Iowa return for tax year ending September 30, 1995, on July 15, 1996, showing an overpayment of $700 and a credit to estimated tax of the same amount. X's amended return was filed on or before September 30, 1996, so the $700 credit to X's estimated tax for tax year ending September 30, 1996, from the amended return was allowed.
Note that if the amended return had not been filed until sometime in October 1996, the credit from X's original return would have been applied to X's estimated payments for tax year ending September 30, 1996. Since the amended return would have been filed too late for purposes of crediting the overpayment to the taxpayer's estimated tax for the next year, the department would issue X a refund of $200 which is the portion of the overpayment from the amended return that had not been credited to estimated tax from the original return for tax year ending September 30, 1995.
EXAMPLE: Corporation Z filed its 1994 Iowa return in April 1995 showing an overpayment of $400 and a credit to 1995 estimated tax of $400. During processing of Corporation Z's 1994 return it was determined that Corporation Z had a liability of $150 from its 1993 Iowa return. Thus, $150 of the 1994 overpayment was offset against the tax liability from the 1993 return. The remaining portion of the 1994 overpayment of $250 was credited to Corporation Z's estimated tax for 1995.
If the taxpayer has elected to have an overpayment of estimated tax credited to an installment other than the first, interest shall accrue on any assessment of additional tax up to the amount of the overpayment from the date the return was filed with the department. Interest on any assessment of additional tax greater than the amount of the overpayment shall accrue from the due date of the return, Avon Products, Inc. v. United States, 588 F.2d 342 (2nd Cir. 1978), Revenue Ruling 84-58.
