26 C.F.R. § 1.6154-3 Extension of time for paying estimated tax.
Title 26 - Internal Revenue
An extension of time granted a corporation under section 6081 for filing the declaration of estimated tax automatically extends the time for paying the estimated tax (without interest) for the same period. See §1.6074–3 for rules relating to extensions of time for filing declarations of estimated tax by corporations. Except as provided in paragraph (b) of §301.6091–1 (relating to hand-carried documents), an application for an extension of time for paying an installment of the estimated tax shall be addressed to the internal revenue officer with whom the taxpayer files its declaration. Each application must contain a full recital of the causes for the delay. Any such extension will not relieve the taxpayer from the addition to the tax imposed by section 6655, and the period of the underpayment will be determined under section 6655(c) without regard to such extension.
