Either you're not reading the original post or you're not understanding it. Taxes paid by corporations, any companies or businesses for that matter, come from the ultimate consumer. Where do you think that they get the money to pay taxes? When their wholesale and retail prices for goods and services are determined, the taxes on profit is added to the price. Corporations and business don't actually pay. all taxes are paid by the consumer.

Now would prices come down if there were no corporate tax?
Some people might say no because these greedy corporations would just keep the extra money. But that ignores one thing, competition. One of these greedy corporations would figure out that if they lowered their prices they would sell more and make more money overall. Soon, other companies, corporations, and businesses of all types would have to lower their prices to stay competitive. They wouldn't do it out of concern for their fellow man or the population in general. They would lower prices out of greed and a thirst to be number one.

Now, if you don't think this is true think about it another way. Let's say we get rid of all individual income taxes and make corporations, companies, and businesses pay at a 90% tax rate. What do you think would happen to prices? Do you think they would go up?

If you understand nothing else, understand the idea that corporations only collect money from the consumers and give it to the government. The more they have to pay in taxes, the more we'll pay for goods and services.
