This paper examines the expected economic cosequences of consolidated tax return system which recent archival studies have claimed to be useful for improving the horizontal equity of Korean corporate tax system. An empirical analysis shows no signficant difference in the horizontal tax equity between consolidated groups and non-consolidated firms under the current tax system. Further analysis also proves that the tax equity of consolidated groups is not expected to increase even under the consolidated tax system. Regression results are exactly consistent with my prediction that Korean consolidated groups have already been minumizing their corporate tax by shifting the high-tax affiliate`s income to the low-tax ones through intra-group sales. These results provide early enidence confirming that consolidated tax system will not improve the horizontal equity of Korean corporate tax system, and the reduction of corporate tax revenue will not be so substantial as the recent archival studies and Korean tax authority have argued.
