I'm sure the government would like to know about your income, so yes. You could do this as a sole proprietor and file on your personal income tax. You'll have to use your social security # as your Federal Employer Identification Number.
Really, the only advice I would suggest going off of is that of an attorney. While there are some knowledeable persons here, its generally not good policy to trust the opinions of those that arent certified to give them, especially when its your livelyhood on the line.
