Answer:
I'd recommend calling your local tax office, but from what I know you will need to pay taxes on your net income.
Explanation:
My knowledge isn't too strong outside of PA and TX, and I'm not a tax official. If you're talking about the items you buy, you may be able to get something that's usually called a Sales Tax Exemption or Reseller Exemption. I'm assuming you're talking about sales tax on items sold, though.
