Time and manner.
Time and manner. A taxpayer to whom the election is available makes the election by filing a return for the short taxable year ending the day before commencement of the case (the first short taxable year) on or before the 15th day of the fourth full month following the end of that first short taxable year. The spouse of such a taxpayer makes the election by making a joint return with the taxpayer for that first short taxable year within the time prescribed in the preceding sentence. To facilitate processing, the taxpayer should write Section 1398 Election at the top of the return. A taxpayer may also make the election by attaching a statement of election to an application for extension of time for filing a return that satisfies the requirements under section 6081 for the first short taxable year. The application for extension must be submitted under section 6081 on or before the due date of the return for the first short taxable year. The statement must state that the taxpayer elects under section 1398(d)(2) to close his or her taxable year as of the day before commencement of the case. If the taxpayer's spouse elects to close his or her taxable year, the spouse must join in the application for extension and in the statement of election. If a joint return is not filed for the first short taxable year, the election of the spouse made with the application is void.
