How the IRS decides whom to go after

OK, so the lesson is don't drive a fancy car, don't train for a marathon, don't talk about your finances to attractive women. On those three grounds, I think that I am safe. But it seems that the IRS will stop at nothing once they see you are driving a fancy car or training for a marathon. From the NY Times:

As a young man, Mr. Engle had been a serious drug addict, but after he got clean, he became an ultra-marathoner, one of the best in the world. In the fall of 2006, he and two other ultra-marathoners took on an almost unimaginable challenge: they ran across the Sahara Desert, something that had never been done before. The run took 111 days, and was documented in a film financed by Matt Damon, who served as executive producer and narrator. Mr. Engle received $30,000 for his participation.

The film, “Running the Sahara,” was released in the fall of 2008. Eventually, it caught the attention of Robert W. Nordlander, a special agent for the Internal Revenue Service. As Mr. Nordlander later told the grand jury, “Being the special agent that I am, I was wondering, how does a guy train for this because most people have to work from nine to five and it’s very difficult to train for this part-time.” (He also told the grand jurors that sometimes, when he sees somebody driving a Ferrari, he’ll check to see if they make enough money to afford it. When I called Mr. Nordlander and others at the I.R.S. to ask whether this was an appropriate way to choose subjects for criminal tax investigations, my questions were met with a stone wall of silence.)

Mr. Engle’s tax records showed that while his actual income was substantial, his taxable income was quite small, in part because he had a large tax-loss carry forward, due to a business deal he’d been involved in several years earlier. (Mr. Nordlander would later inform the grand jury only of his much lower taxable income, which made it seem more suspicious.) Still convinced that Mr. Engle must be hiding income, Mr. Nordlander did undercover surveillance and took “Dumpster dives” into Mr. Engle’s garbage. He mainly discovered that Mr. Engle lived modestly.

In March 2009, still unsatisfied, Mr. Nordlander persuaded his superiors to send an attractive female undercover agent, Ellen Burrows, to meet Mr. Engle and see if she could get him to say something incriminating. In the course of several flirtatious encounters, she asked him about his investments.

After acknowledging that he had been speculating in real estate during the bubble to help support his running, he said, according to Mr. Nordlander’s grand jury testimony, “I had a couple of good liar loans out there, you know, which my mortgage broker didn’t mind writing down, you know, that I was making four hundred thousand grand a year when he knew I wasn’t.” . . .
