If every sale requires a tax, then there will be an increase in prices. Companies are in business to make money, the only ones deliberately selling at a loss are those that are spending capital to create market share. How many retailers do you know of who rebate the sales tax so they can sell more stuff at a lower mark up?
Go back to you economics text book and study what happens to the supply curve when prices go up.
