What the policy did

Lee-government tax package restoring the corporate-tax burden to what MOEF calls a normal level while also using capital-market tax relief to support the Korea-premium agenda. The package reversed part of the Yoon-era corporate-tax cut by restoring the headline burden for large corporations, but paired this with a lower separate tax rate for dividend income and a reduced inheritance-tax burden intended to encourage corporate value-up and family-business continuity. The policy therefore moves corporate taxation upward while easing some capital-income and inheritance taxation.

Policy-content fingerprint — what this policy moved, on which axes

In an OECD-country panel 2014-2024, reductions in the top statutory capital- gains tax rate predict higher subsequent gross fixed capital formation as a share of GDP and higher business-startup rates, controlling for corporate-tax rates, interest rates, and institutional quality.

The 2000 Schroder corporate + personal tax reform package (top personal rate cut from 53 to 42 percent staged 2000-2005, corporate rate cut from 40 to 25 percent, capital-gains exemption on inter-corporate shareholdings) is associated with a 1.0 to 1.5 percentage point rise in the German top-1 pre-tax income share over 2000-2008 vs Eurozone synthetic control, but no measurable rise in aggregate output growth beyond Eurozone trend.

Estonia's 1994 flat-tax 26 percent (subsequently reduced to 20 percent by 2015) and the unique 2000 corporate-tax reform (taxing only distributed corporate profits) produced a measurable rise in the Estonian top-1 pretax income share over 1994-2010 vs Baltic synthetic comparator (LVA, LTU), with the distributed-profit-only corporate regime channelling capital-income into top-decile reported income while reducing taxation of retained earnings.

The 2003 Jobs and Growth Tax Relief Reconciliation Act (JGTRRA), which cut US qualified-dividend and long-term-capital-gains rates to 15 percent, shifted the composition of top-1 pre-tax income toward dividend and capital-gains realisations between 2003 and 2007, raising the top-1 share by 1.5 to 3 percentage points relative to the pre-2003 trend.

Second-tranche Asia pass revised the capital-tax coding to match the official MOEF growth-strategy description: corporate tax was restored upward, while inheritance/dividend taxation was eased.
