Indirect taxes are taxes collected by intermediaries in the supply chain but ultimately paid by consumers through higher prices. They contrast with direct taxes which are paid directly to the government by the person being taxed. Common indirect taxes include import duties, sales taxes, and carbon taxes. While they are a major source of government revenue, indirect taxes are often considered regressive since they place a higher relative burden on low-income individuals. They also lack transparency and can distort markets. However, they are generally convenient to administer and difficult to evade.
