While the United States may not have a federal flat income tax, several states have implemented flat-rate individual income taxes, including Colorado, Illinois, Indiana, Massachusetts, Michigan, North Carolina, Pennsylvania, and Utah. Other countries among the 24 with a flat tax include Belarus (13%), Belize (25%), Bulgaria (10%), Georgia (20%), Hungary (15%), Kazakhstan (10%), Mongolia (10%), Romania (10%), and Saudi Arabia (20% on foreign residents). In 2001, Russia implemented a 13% flat tax on individual income, which it has retained to this day. Since 1994, Estonia has had a simple flat tax, currently 20%, and the Tax Foundation ranks it the most competitive in the world.

While the flat tax has lost steam as the basis for tax reform in the United States today, it’s currently in use in 24 countries around the world. In 1995 the flat tax was proposed again but never made it to the House or Senate floors. Just a few years later, under President Clinton, additional brackets effectively gutted what had been a relatively flat tax system. In 1990, Congress added a third rate of 31% on higher incomes, reducing the simplicity of the tax structure. Two rates of 15% and 28% replaced the prior system’s multiple tax brackets. The flat-tax proposal gained steam in the 1980s and inspired President Reagan’s Tax Reform Act of 1986. Their Wall Street Journal article “A Proposal to Simplify Our Tax System” featured an image of a postcard that became symbolic of the flat-tax movement, as the simplicity it proposed would allow a business or individual to file tax returns via a postcard-sized form. They believed that the flat tax is the fairest and most efficient, simple, and workable tax plan.
