I 2nd roger. You should talk to your parents about the savings they get from claiming you. Usually in order to get any type of education credits they must claim you - so if they are paying a ton for your college then it is probably the best for them to continue claiming you until you finish school.
However, if you do successfully start a business and show substantial profits then you will see you tax liability be extremely high especially without even being able to take your own deduction for yourself.
My recommendation (based on knowing nothing about your business) - make sure you write off EVERYTHING you can including all expenses relating to the startup of your new business. Most small startup businesses even though profitable can easily show little to no profits or even a loss after writing off everything.
