26 CFR § 1.6081-1 - Extension of time for filing returns.
(a) [Reserved]. For further guidance, see § 1.6081-1T(a).
(b)Application for extension of time -
(1)In general. Under other sections in this chapter, certain taxpayers may request an automatic extension of time to file certain returns. Except in undue hardship cases, no extension of time to file a return will be allowed under this section until an automatic extension of time to file the return has been allowed under the applicable section. No extension of time to file a return will be granted under this section for a period of time greater than that provided for by automatic extension. A taxpayer desiring an extension of the time for filing a return, statement, or other document shall submit an application for extension on or before the due date of such return, statement, or other document. If a form exists for the application for an extension, the taxpayer should use the form; however, taxpayers may apply for an extension in a letter that includes the information required by this paragraph. Except as provided in § 301.6091-1(b) of this chapter (relating to hand-carried documents), the taxpayer should make the application for extension to the Internal Revenue Service office where such return, statement, or other document is required to be filed. Except for requests for automatic extensions of time to file certain returns provided for elsewhere in this chapter, the application must be in writing, signed by the taxpayer or his duly authorized agent, and must clearly set forth -
(ii) An explanation of the reasons for requesting the extension to aid the internal revenue officer in determining whether to grant the request.
(2)Taxpayer unable to sign. In any case in which a taxpayer is unable, by reason of illness, absence, or other good cause, to sign a request for an extension, any person standing in close personal or business relationship to the taxpayer may sign the request on his behalf, and shall be considered as a duly authorized agent for this purpose, provided the request sets forth the reasons for a signature other than the taxpayer's and the relationship existing between the taxpayer and the signer.
(c)Effective/applicability dates. This section applies to requests for extension of time filed after July 1, 2008.
