Yes, you can hire an independent contractor who does not have a  "corporate" structure (e.g. a corporation or LLC). All you absolutely need is his/her social security number, which will used on the 1099, etc. However, there are other things you should have:1) Have him/her sign an agreement confirming that he/she is an independent contractor, not an employee, and is resonsible for own taxes, own benefits, etc.2) Have him/her provide proof of any insurance which it would be good for him/her to have to protect you (e.g. liabiliity insurance), naming you/your company as an additional payee.3) If the contractor requires a license for his/her profession or trade, get a copy of said license.
