Well no one has ratted him out as of yet. When he dies though they will go after his wife if she's still alive. When my Dad died the IRS came after my Mother because my Dad hadn't filed anything for a few years. He owned his own business and things got put aside after he got sick. My Mom didn't know anything about taxes or anything, he took care of all of that. But she had to pay back taxes and it took a long time and it was a great deal of turmoil for her, so unless you have no social security number they'll find you eventually.
