It is a presumption that Romney could rebut by releasing his tax returns since he took over running the Salt Lake City olympics. Romney has chosen not to rebut the presumption.
Michael Graetz, who knows what he is talking about:
The Mysteries of Mitt Romney’s Financial Records: Some commentators have suggested, for example, that — like tens of thousands of other Americans who have taken advantage of an Internal Revenue Service amnesty — he might not have declared and paid taxes on his Swiss bank account. I can’t imagine that he would have engaged in such blatant tax cheating. He is far too smart for that….
[T]he one year’s tax returns that he has released raise doubt about his campaign’s claims that his offshore accounts did not save him one penny of tax. Putting business assets into an individual retirement account invested in a Cayman Islands corporation allows Mr. Romney to avoid the “unrelated business income tax” — a 35 percent levy — on at least some of his I.R.A.’s earnings…. With an I.R.A. account of $20 million to $101 million, the tax savings would be more than a few pennies….
Given the extraordinary size of his I.R.A., we have to presume that Mr. Romney valued the assets he put in his retirement account at far less than he would have sold them for. Otherwise it is quite a trick to turn contributions that are limited to $30,000 to $50,000 a year into the $20 million to $101 million he now has there…. Mr. Romney’s Cayman Islands and Bermuda corporations also probably allowed him to avoid limitations on deductions for investment expenditures that would otherwise apply. So we don’t need any more tax returns to know that Mr. Romney is an Olympic-level athlete at the tax avoidance game. Rich people don’t send their money to Bermuda or the Cayman Islands for the weather.
Moreover, we have no clue whether Mr. Romney paid any gift tax on transfers, now valued at $100 million, to a trust he set up in 1995 for the benefit of his five sons. Until this year, the federal gift tax had a lifetime exemption of $1 million, and it taxed gifts in excess of that amount at rates between 29 and 44 percent. A gift of $100 million to one’s children could, therefore, require paying a tax of as much as $29 million to $44 million.
But every good tax professional knows that gift tax returns are rarely audited, except after the transferor’s death. And normally the I.R.S. cannot challenge such a return after three years from its filing. But if the values of the gifts were not properly appraised and disclosed on Mr. Romney’s gift tax returns, a challenge may still be possible. If he did not file any gift tax return, he would still be liable for the tax, plus interest and penalties….
[M]y bet is that — if Mr. Romney filed a gift tax return for these transfers at all — he put a low or even zero value on the gifts, certainly a small fraction of the price at which he would have sold the transferred assets to an unrelated party. Otherwise, he should be happy to release his gift tax returns. According to a partner at Mr. Romney’s trustee’s law firm, valuing carried interests, such as Mr. Romney’s interests in the private equity company Bain Capital, at zero for gift tax purposes was common advice given to clients like Mr. Romney in the 1990s and early 2000s.
If detected, undervaluing large gifts to one’s children could provoke large penalties from the I.R.S. These are the kinds of tax penalties that even multinational corporations try to avoid because they fear how the public would react to the adverse publicity that would inevitably follow….
No one should begrudge Mr. Romney or his family the wealth they have earned. But if he has not paid the taxes that apply to transfers of such wealth, this should concern us all. After all, who do you think pays for the shortfall?
It looks to me as though a full audit of Romney's taxes would likely produce an unpaid tax liability on the order of $50 million--plus penalties
