I have a question...my 20 yr old cousin worked for a contractor last year "off the books" so to speak. Actually he was being ran through a temp agency for awhile and then they both supposedly agreed to treat him like a sub-contractor even though he didn't have a license. My cousin received a 10-99 for $20,000 for 2006, however, he also received a 10-99 for part of 2005 (but he is young and didn't do his taxes that year). He had to pay over $7000 in taxes this year!!! Do you think he has a case to sue that contractor for taking advantage of him? He tried to send him a certified letter saying he wants him to pay part of his taxes, but the guy wouldn't accept the letter. Any response would be very much appreciated!
