Tax Court Maintains that Reg. 1.6015-5(b)(1) is Invalid Interpretation

In a case appealable to the Sixth Circuit Court of Appeals, the Tax Court maintains that Treas. Reg. 1.6015-5(b)(1) is an invalid interpretation of IRC 6015(f) in circuits other than the Seventh Circuit (where such a ruling was overturned in Lantz v. Commissioner).
