Generally, individuals under the age of 18 are not legally able to start a business in their own name; they need parental or guardian consent, or the involvement of a parent or guardian to do so.
Make sure you and your parents sit down with an attorney and an accountant before you get started; otherwise, if your business goes under, your parents might find they're saddled with some nasty (and unanticipated) obligations.
