Summary
This topic explains how to calculate the tax payments of individuals or households and how to express those payments relative to income. At HL, students must work with indirect taxes, total tax paid and average tax rates, distinguish average from marginal rates, and use these calculations to judge whether a tax system is progressive, proportional or regressive. These measures let economists compare tax burdens across income groups and assess distributional effects.
