Overview
Welcome to the IDEAS website, an online tool that helps people explore and compare tax rates across all states over time, as well as see how certain taxes impact everyday decisions. Within this website, you can create your own charts and tables, and you have access to a large comprehensive dataset that includes roughly 50 variables per state, over a span of decades.
ABOUT:
The data are divided into three main categories: economic aggregates, fiscal policy measures, and demographics. This database includes an archive of additional information that includes specific selective tax rates, public employee information, and overall tax burdens.
WHO MAINTAINS THIS SITE:
Dr. Arthur Laffer, of Laffer Associates in Nashville, Tenn., began maintaining this dataset in 1977 and transferred ownership to the Show-Me Institute in 2009. The Show-Me Institute now maintains this dataset and makes it available to scholars, media, and the general public to use.
