So...I provide content services for people. I have a new client that doesn't want to pay me through Paypal. She wants to mail me a check or send it electronically through the bank. She wants to put me on a 1099 form. Besides the fact that this means I have to report the income at the end of the year (which I would have done anyways), is there any reason I shouldn't do a 1099 with this person? I don't know her from Adam, so she would have my SS# instantly. Other than taxes and personal information, I can't think of any reason I shouldn't do this. Are there other tax consequences for me? I am a sole proprietor for now.
