I believe the majority of my clients either can't read or refuse to read what I provide to them.  If I added "check this box and return with your completed organizer to receive $100 cash", it wouldn't cost me more that $500 for all of tax season.  A few of them would check the box and then keep the form at home.  A few more would circle the box.  Another handful would call and ask what that meant.  A few of that handful would ask if they had to bring in $100 cash with them when they dropped off their return.  And of course a large percentage of them would just bring back the sheet along with the organizer, unopened in the envelope that I mailed the organizer in.

Why did you have to post this question?  Now you have me depressed just thinking of tax season 😢
