- 9 - Manual (CCH), pt. 5.19.2., at 18,303 (Apr. 1, 2007). Given their past problems with filing income tax returns, petitioners should not have relied on the IRS to notify them that their 1996 amended return and their 1997 return had not been received. If the IRS had not sent petitioners any notification that their 1997 return was delinquent before 2002, this would not be an unreasonable error or delay under section 6404(e) because that section does not permit abatement of interest regardless of how long the IRS takes to first contact the taxpayer. Downing v. Commissioner, 118 T.C. 22, 30-31 (2002); Cannon v. Commissioner, T.C. Memo. 2002-205; Hanks v. Commissioner, T.C. Memo. 2001-319. Therefore, we find it was petitioners’ error that ultimately caused the delay in petitioners’ payment of their 1997 income tax liabilities. We agree with petitioners that they generally have a reasonable expectation that items they send in the mail will be received. However, because petitioners were aware that several of the returns they mailed to the IRS were not received, petitioners should have taken steps to ensure that the IRS received their subsequent returns. Furthermore, petitioners have not offered any evidence showing that the IRS’s failure to receive petitioners’ amended 1996 return or 1997 return before 2002 was due to any error committed by the IRS. Because petitioners bear the burden of proof, the absence of any evidencePage: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: March 27, 2008
