Well it is the truth. I don't factor in my income tax into my prices because it is impossible to know ahead of time. I work to maximize profits by offering products at a competitive price while keeping my costs down. Maximizing profits will cause my income taxes to go up, but I do not charge my customers more because I am now making more money.
Ridiculous. Even if you don't explicitly factor those taxes in, you have to charge enough so that your after-tax profits are enough to justify the investment of time and money into your business. Just because you're not doing it consciously doesn't mean you're not doing it.
