On the back of the form it states that you are chosen randomly by driver's lic., gross income tax filed, and homestead rebate application. The only thing that I can think of is that in 2001 he received money from my sister who passed and I think he had to file taxes that year.
In NJ you have to fill out the form and return it. One of the questions is are you 18yrs or older. The answer NO was in the disqualifying box so I don't have to call them and he doesn't have to report (unless I hear from them )
