Experts claim the four techniques cut the tax bill from 38.6% to just 18% for which the firm is paid a hefty sum for its advice - 6% to 8% of the tax bill plus $50,000 for a lawyer's letter of opinion.

In defending the techniques, Ernst & Young said at least one of them has been disclosed to the IRS and the government office has not challenged it.
