The vast majority of the 1.6 million taxpayers whose refunds were secretly frozen over the last five years appear to have done nothing wrong, the I.R.S. taxpayer advocate told Congress two weeks ago. The advocate, Nina E. Olson, told Congress that her staff sampled the frozen returns and found that among those who pressed for a refund, two-thirds were due all or more than what was requested and most of the remaining 20 percent of cases seemed to involve issues other than fraud. Congress created the advocate position inside the I.R.S. as a way to give taxpayers a voice.
