According to a definition, windfall tax can be explained as, “a tax levied on an unforeseen or unexpectedly large profit, especially one regarded to be excessive or unfairly obtained.” Broadly speaking, a windfall tax is a charge or surtax levied by governments against certain industries when these industries experience above-average profits due to economic expansion. Windfall taxes are generally imposed on companies in the targeted industry that have benefited the most from the economic windfall, most often commodity-based businesses.
