Hello, I am trying to figure out why my new employer is trying to have me sign a 10-99 tax form. I am not trying to sell myself as a contractor. I am as of right now just an assistant. I have two more years until I can take the test out here in buffalo. I just want to make sure I have all my bases covered. I also do not want to have my own insurance coverage being considerd a sub-contractor. Why would an employer want me to do a 10-99? He says it has something to do with his health insurance coverage. I don't need health insurance though. I am covered under my parents for the next three years. Also are there any advantages for me to do this? If I do sign this one will I owe this tax season.
