October 7, 2002119 T.C. 157
The court granted petitioners’ motion for partial summary judgment on whether their charitable transfers of stock warrants were anticipatory assignments of income. Treating the applicable revenue ruling as a concession by the Commissioner, the court held that the relevant inquiry was whether the charitable donees were…

February 1, 2001116 T.C. 73
The Tax Court denied the Commissioner's motion for partial summary judgment, holding that the so-called 'one claim' rule of section 6427(i)(1) does not bar FPL Group from obtaining additional fuel tax credits under section 34 beyond the amounts claimed on its original consolidated returns for 1988 through 1992.
The Court dismissed the taxpayer’s petition because he had received a notice of deficiency and therefore could not challenge the existence or amount of that liability in a later collection-review proceeding.

The Tax Court denied Kathryn Cheshire innocent spouse relief under sections 6015(b) and (c) for omitted retirement distribution proceeds and interest income because she had actual knowledge of the items giving rise to the deficiency, holding that actual knowledge of an 'item giving rise to a deficiency' under section…

April 28, 2000114 T.C. 276
The Tax Court denied Jean Butler innocent spouse relief under section 6015(b)(1), holding that her college education, experience operating her own S corporation, control of the family's finances, the couple's ongoing IRS disputes over prior years, and her actual knowledge of her husband's BGE-DuPont settlement gave…
The Tax Court held that it has jurisdiction under section 6330(d) to review the Commissioner's notice of determination authorizing levy of Howard Goza's 1994-1996 income taxes, even though Goza never petitioned for redetermination of the underlying notice of deficiency.
The Tax Court sustained the Commissioner's bank-deposit-based increases to petitioner's gross receipts for 1990-1992 and disallowed nearly all of his Schedule C deductions for lack of substantiation, allowing only conceded items plus telephone expenses of $7,735 (1990) and $6,616 (1991).
