Well, if they die while awaiting arrival of the IRS people, I guess they've won, in a sense. If it takes 10 years for the agency to really get serious, I have a hunch some folks would be far ahead to simply stop complying. Point out the error of my thinking, please.
10 years is the statute of limitations. As they get closer to that date they ramp up collection actions. They have nothing to lose by waiting because the interest and penalties rack up and it is a pretty good return on their money.
