Bloomberg is reporting that Mitt Romney rented the Mormon Church’s nonprofit status to avoid taxes, meaning that he probably paid next to no taxes for the decade ending in 2009:

In 1997, Congress cracked down on a popular tax shelter that allowed rich people to take advantage of the exempt status of charities without actually giving away much money.

Individuals who had already set up these vehicles were allowed to keep them. That included Mitt Romney, then the chief executive officer of Bain Capital, who had just established such an arrangement in June 1996.

The charitable remainder unitrust, as it is known, is one of several strategies Romney has adopted over his career to reduce his tax bill. While Romney’s tax avoidance is legal and common among high-net-worth individuals, it has become an issue in the campaign. President Barack Obama attacked him in their second debate for paying “lower tax rates than somebody who makes a lot less.”

In this instance, Romney used the tax-exempt status of a charity — the Mormon Church, according to a 2007 filing — to defer taxes for more than 15 years. At the same time he is benefiting, the trust will probably leave the church with less than what current law requires, according to tax returns obtained by Bloomberg this month through a Freedom of Information Act request.

In general, charities don’t owe capital gains taxes when they sell assets for a profit. Trusts like Romney’s permit funders to benefit from that tax-free treatment, said Jonathan Blattmachr, a trusts and estates lawyer who set up hundreds of such vehicles in the 1990s.

Near Zero

“The main benefit from a charitable remainder trust is the renting from your favorite charity of its exemption from taxation,” Blattmachr said. Despite the name, giving a gift or getting a charitable deduction “is just a throwaway,” he said. “I used to structure them so the value dedicated to charity was as close to zero as possible without being zero.”

It would have been nice if the press had gotten this earlier, but it sure looks like Rmoney’s tax returns have been kept under wraps because he lied when he claimed that he was paying a reasonable amount of taxes.
