Remember In CC-2010-016, the Chief Counsel's Office set forth the IRS litigating position:
a Form 1040 is not disqualified as a “return” under Bankruptcy Code §523(a) solely because it is filed late, but—regardless of whether a Form 1040 filed after assessment is a “return”—the portion of a tax assessed before such a form is filed is nondischargeable under Bankruptcy Code §523(a)(1)(B)(i).
See also SBSE-05-1010-052 (providing guidance on determining dischargeability of Form 1040 tax liability when form is filed later and after assessment of substitute for return under §6020(b) or during assessment of substitute for return) (expiration date 9/29/2010) (available at http://www.irs.gov/pub/foia/ig/sbse/sbse-05-1010-052.pdf).
