A taxpayer may raise challenges to the existence or the amount of the taxpayer’s underlying tax liability if the taxpayer did not receive a notice of deficiency or did not otherwise have an opportunity to dispute the tax liability. Sec. 6330(c)(2)(B). Respondent issued a notice of deficiency to petitioners with respect to their taxable year 1988. Petitioners filed a petition with the Court with respect to that notice. On January 9, 2001, the Court entered a decision in petitioners’ Tax Court case, which was affirmed by the Court of Appeals for the Eighth Cir- cuit. The Tax Court decision provided, inter alia, that for petitioners’ taxable year 1988 there were a deficiency of $55,550 in petitioners’ tax and additions to that tax under sections 6653(a) and 6661 of $2,777.50 and $13,887.50, respectively. On the instant record, we find that petitioners may not challenge the existence or the amount of the underlying tax liability for their taxable year 1988.
