I am 47. I have worked as a short order cook in small restaurants all my life. I only ever filed taxes once, when I was 19, and have never filed since. I am not an illegal alien, I was born and raised in the US. I've worked in 4 different states, and I would estimate at *least* 40 different restaurants, some that are now out of business, some who's names I can't even remember. I have never received any notices from the IRS. Should I just start filing my taxes again?
