Contrary to the claims of some flat tax proponents, flat taxes do not lead to lower taxes across the board. Flat taxes usually bring lower tax bills for high-income households and, because of that, they produce less revenue than graduated taxes during times of rising inequality. For most families, however, there is nothing inherently “low tax” about flat taxes. In fact, flat taxes often actually result in higher overall taxes than other tax structures.
