The R&D Tax Credit was first introduced in the United States through the Economic Recovery Tax Act of 1981.  With worries that the U.S. was falling behind in production and innovation relative to the global economy, the Economic Recovery Tax Act aimed to stimulate the U.S. economy and encourage investment within the United States. Though this tax credit was originally only anticipated to last for two years, the PATH Act of 2015 permanently extended the R&D Tax Credit due to the immense value that research and development brings to the U.S. economy each year.
