March 25, 2021, is the fortieth anniversary of the beginning of the flat tax movement. I include an op-ed that was published on March 25, 1981, in the Wall Street Journal. I wrote it four months after Ronald Reagan’s Tax Policy Task Force submitted its report upon his election. My motivation for the op-ed was that while the Task Force’s recommendations, which were largely adopted, improved the then current federal income tax code, they did not go nearly far enough to simplify and fix other flaws in the tax code.
