Bain private equity funds in which the Romney family's trusts are invested appear to have used an aggressive tax approach, which some tax lawyers believe is not legal, to save Bain partners more than $200 million in income taxes and more than $20 million in Medicare taxes.
Annual reports for four Bain Capital funds indicate that the funds converted $1.05 billion in accumulated fees that otherwise would have been ordinary income for Bain partners into capital gains, which are taxed at a much lower rate.
Although some tax experts have criticized the approach, the Internal Revenue Service is not known to have challenged any such arrangements.
In a blog post Thursday, Victor Fleischer, a law professor at the University of Colorado, said that there was some disagreement among lawyers, but that he believed: "If challenged in court, Bain would lose. The Bain partners, in my opinion, misreported their income if they reported these converted fees as capital gain instead of ordinary income."
