That makes no sense. You set the price according to whatever gets you the highest profit. You then pay the tax on the profit. There is no room to adjust the margins of the product based on your profit expectations. By that logic my profit expectation could be 1 trillion and I just set the margin based on that since prices are infinitely elastic and the consumer will always pay whatever I charge. No, a competitor will steal your customers and you will end up making less money.

What the corporate income tax may do is encourage the company to defer its profits overseas and wait for tax holidays or tax cuts. It may also discourage investors from investing in your country. Those are pretty huge downsides but they have nothing to do with product pricing.
