Do Tax Cuts Increase Revenue?
Do Tax Cuts Increase Revenue
It is a widely held belief in the U.S. that cutting tax rates actually increases government tax revenues, as people work harder to make more money, and having more money (either from working longer hours or simply because they have more income after paying lower taxes), they spend more. This increased consumption stimulates growth in the business sector of the economy, increasing business profits, allowing businesses to hire more employees, etc. and the economy grows. Economic growth then leads to more tax revenues for the government, even though taxes have been reduced.
While this view has gained political currency, there is little evidence to support it. Indeed, as evident in the following graph, the evidence suggests that tax cuts do not increase revenues to the government in any meaningful way, but instead increase government deficits. Likewise, tax increases are often criticized as harmful to the economy and opponents argue that they do not actually increase government revenues. Again, the available evidence suggests that the opposite is true.
