I live in TX, which does not have a state income tax. I am currently a college student, and my only source of income comes from online poker, where ive made about 4 thousand this year. I have not kept track of every session like i think your suppose to. But how should i go about filing for taxes? and would i be classified as a pro, since its basicly like a job to me, and no other source of income. And also how much would i have to pay to the IRS for federal income tax. ty
