Which terms best describe sales tax? Check all that apply.
Crazy boy [7]

The answer is <em>Sales Tax</em> can be described as Indirect and Regressive. It is indirect because the retribution that the consumer is going pay is collected by the seller, who acts as an intermediary between the people and the government and then is handed to the government (contrary to the direct type in which the taxation amount goes directly into the government's arks).

This type of system is also regressive because it doesn't change (increasing or decreasing) according to the payer's income. Instead, it puts a heavier contribution load on the people with lower incomes, and not on the rich and more wealthy part of the population.
