[2026 Tax Revision Plan] Tax cuts for companies that ‘produce domestically’... using tax policy to steer industries and capital to regional areas

South Korea’s 2026 tax plan introduces a new corporate tax credit for producing strategic goods domestically, with larger benefits outside the Seoul metro area.

The government also plans a new long-term ISA to channel savings into domestic stocks and bonds, aiming to keep more capital at home.

The shift is designed to strengthen supply chains, support advanced industries, and promote balanced regional growth.

At the same time, 115 of 241 tax expenditures will be ended or redesigned as part of a broader overhaul.
