The executor must file a federal income tax return (Form 1041) if the estate has: 1  gross income for the tax year of $600 or more, or. 2  a beneficiary who is a nonresident alien.
During the chapter 7 or 11 bankruptcy, the debtor continues to file an individual tax return on Form 1040. The bankruptcy trustee files a Form 1041 for the bankruptcy estate. However, when a debtor in a chapter 11 bankruptcy case remains a debtor-in-possession, he or she must file both a Form 1040 individual return and a Form 1041 estate return for the bankruptcy estate (if return filing requirements are met).
