The Economic Recovery Tax Act (ERTA) of 1981 was a significant piece of legislation aimed at stimulating the U.S. economy by implementing substantial tax cuts for individuals and businesses. This act was part of the broader conservative agenda during the Reagan administration, reflecting a shift toward supply-side economics, which emphasized lower taxes to encourage investment and economic growth. The ERTA not only reduced individual income tax rates but also provided incentives for businesses, hoping to spur job creation and enhance overall economic performance.
