Memo. 2001-34; Deal v. Commissioner, T.C. Memo. 1999-352; Duffy v. Commissioner, T.C. Memo. 1996-556; Pulliam v. Commissioner, T.C. Memo. 1996-354. Petitioner also argues that his ignorance of the 10-percent additional tax should except him from liability to pay it. However, as a general rule, taxpayers are charged with knowledge of the tax laws. Harrington v. Commissioner, 93 T.C. 297, 314 (1989). We conclude that under section 72(t) petitioner is liable for the 10-percent additional tax with respect to his $37,200 early IRA distribution. To reflect the foregoing, Decision will be entered for respondent. 1 Not applicable to petitioner’s financial hardship (and not effective before Dec. 21, 2005) is a statutory exception to the imposition of the additional tax under sec. 72(t) applicable to certain victims of hurricanes Katrina, Rita, and Wilma. Sec. 1400Q(a)(1), (4)(A); Gulf Opportunity Zone Act of 2005, Pub. L. 109-135, sec. 201(a), 119 Stat. 2596.Page: Previous 1 2 3 4 5Last modified: March 27, 2008
