Companies charge for their products and services as much as they can get away with charging, quite independently of taxes - it's all about how much customers will pay, not about taxes.
The only taxea companies collect for the State are Sales Taxes.
Your view is the same delusion about how Markets works as the one were companies will raise salaries if they increase prices: no they won't, they charge as much as they can get away with and pay as little as they can get away with since what's in between the company owners (and upper management) get to keep.
This is basic Economics.
