This document is the annual IRS filing from the Institute for Energy Research (IER) for the calendar year 2018.

The Institute for Energy Research was originally co-founded by Charles Koch and former Enron executive Robert L. Bradley in 1984, under the name “Institute for Humane Studies of Texas.” As first reported by Lee Fang for Republic Report in 2014:

“In October of 1984, Charles, then using a Menlo Park, California address founded a non-profit called the Institute for Humane Studies of Texas. That organization briefly lost its charter in 1989 for failure to pay the Texas state franchise tax. Four years later, incorporation documents reveal, the group rebranded as the Institute for Energy Research, or IER, which later formed a subsidiary called the American Energy Alliance.”
