Last March I began working for an elderly woman as her "assistant." She hired me on as an independent contractor, which at the time I was unfamiliar with. After working through the summer I decided it wasn't the job for me; I felt like she was taking advantage of me. Anyway, she just emailed me asking for my social, which I of course asked her why and told her I did not feel comfortable with.
So she sent me a W9 form asking for my social so that she can file a 1099. What do I need to expect from this? And should I fill the W9 out?
