Why are taxes taken into account when calculating the cost of goods?

Taxes are divided into those paid by producers and those paid by consumers. Ultimately, consumers pay everything, because the profit tax that the manufacturer pays is embedded in the cost of the product. But manufacturers do not pay value added tax and receive a deduction for it. It is paid by the consumer himself. Companies strive to maximize their profits and therefore try to account for all their production costs. Risks are also included in the cost of production with varying degrees of probability, and taxes occur every quarter and are quite tangible.
