South Korea's chip boom lifts 2027 corporate tax above KRW200 trillion

South Korea's semiconductor boom is reshaping its fiscal landscape, with corporate tax revenue surpassing income tax for the first time, signaling a deep transformation from technological prowess to economic engine. Upstream, materials and equipment suppliers benefit directly from increased wafer fabrication and advanced process investments, while downstream sectors accelerate AI chip deployment. Compliance risks are mounting as governments tighten foreign investment controls and export restrictions, forcing companies to navigate complex geopolitical landscapes. Globally, the U.S. and EU may intensify domestic support to counter South Korea’s rise. In the next 12–24 months, if Taiwan, China and South Korea solidify advanced process dominance, it could further fragment global supply chains. Tax policy may be leveraged to reinforce strategic industrial alignment.
