In 2000, taxpayer requested equitable relief under IRC Sec. 6015(f) from joint and several liability for her 1997 joint tax underpayment, which the IRS denied. In 2007, taxpayer filed a second request for equitable relief for the same underpayment, providing more detailed factual allegations and alleging that her ex-husband and his business associate had been convicted of criminal securities fraud, which the IRS also denied. The Tax Court held that the second claim for relief was essentially duplicative of the first claim, and was not a qualifying request for relief under Reg. 1.6015-1(h)(5) . In so holding, the court noted that the second request "presented essentially the same factual basis and ground for relief as the first claim for relief and is best characterized as seeking reconsideration of her first request for relief, with reiterations of those claims.
