The Activity: Exploring Tax Rates by Income Level and Tax Type

In this activity, students interact with a graph of average tax rates by income level. The solid black line at the top shows the total effective tax rate at each income level. So, for example, the median American will pay about 24% of their income in taxes.

But Americans don’t just pay one type of tax. Students explore how that total effective tax rate is broken down into sales taxes, payroll taxes, income taxes, corporate and property taxes, and estate taxes.

After more exploration, students apply what they’ve learned to categorize each tax type as progressive, regressive, or proportional (flat).
