Yoon corporate-tax rate cut 2023 (South Korea)

KOR·2023 – present·enacted 2022-12-23·People Power Party (conservative)candidate

What the policy did

Corporate Tax Act amendment (December 2022) cutting the headline top corporate-income-tax rate from 25% to 24% effective January 2023, paired with 1-percentage-point reductions across each of the four statutory brackets (9% / 19% / 21% / 24%) and adjustments to investment-credit and R&D-deduction schedules. The Yoon administration's original proposal was a steeper cut to 22% with three-bracket simplification; the National Assembly (DP majority) compelled the single-point cut as compromise.

Empirical evidence — linked hypotheses

Across 26 Swiss cantons 1990-2023, cantons with persistently lower effective corporate tax rates, looser regulatory burden, and higher Fraser-style sub-national economic-freedom ranks exhibit higher per-capita GDP growth, higher private business formation rates, and higher net inward migration of high-earning workers than cantons with persistently tighter regulation and higher tax rates.

Ireland’s long-run convergence from a middle-income to a high-income economy during 1987–2024 is better predicted by trade openness, tax competitiveness, and FDI entry than by classic industrial planning.

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.

Trump's 2017 Tax Cuts and Jobs Act produced smaller investment and output responses than Laffer-curve advocates projected, consistent with New Keynesian estimates of corporate-tax-cut passthrough in a near-full-employment economy with inelastic long-run investment supply.

Macron 2017-2019 labour-tax reforms produced measurable employment gains but had distributional costs; welfare-state-adjustment outcome is mixed and depends on transfer-side offsets.

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 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.
