amendment known as the Stelly Plan which lowered some sales taxes in exchange for higher income taxes. After taking office, Jindal cut taxes a total of six times, including the largest income tax cut in Louisiana's history – a cut of $1.1 billion over five years, along with accelerating the elimination of the tax on business investments.
