Section 35.01.01.821 - CORPORATE ESTIMATED PAYMENTS: PAYMENTSSection 63-3036A, Idaho Code
01.Underpayments. A payment of estimated tax is to be applied to previous estimated payments of estimated tax in the order in which the estimated payments were required to be paid. To the extent the payment exceeds previous underpayments, it applies to the estimated payment then due.02.Overpayments.a. If the estimated payments exceed the actual tax due, the overpayment may be claimed as a credit against the next payment only to the extent it exceeds all underpayments of prior estimated payments.b. The overpayment is to be applied to deficiencies of tax, penalties, and interest prior to refund or application to a subsequent year's estimated payment or tax liability.c. A refund or credit may not be made to a corporation that fails to file its Idaho income tax return within three (3) years from the due date of the return for which it made the estimated payments.03.Obligation to File Returns. The payment of estimated tax does not relieve a corporation of the obligation to file a return when due pursuant to the Idaho Income Tax Act. An extension of time is not allowed for payment of estimated taxes. Making estimated payments as required in Section 63-3036A, Idaho Code, does not relieve the taxpayer of the requirement to pay the appropriate amount of tax with an application for extension of time to file or with the original return.Idaho Admin.
