Deferred tax was introduced in Korea on April 1st, 1998. The liquidity-classification of deferred tax is to correct and reasonably mediate the distortions of accounting information, coming from the differences of the standards between Net Income of KGAAP and Taxable income. This deferred tax accounting which distributes the impact of temporary difference to the next year is to indicate proper assets and liabilities. As a result, this study allows people to recognize how the evaluating correlation of corporation valuation deferred tax front and rear (June, 2004), in case assets and liabilities are represented, divided into liquid and non-liquid accounts. Ohlson model related to evaluation of corporation valuation is used for the basic model of verification.Assets and liabilities had been represented as non-liquid things in all cases before KGAAP divided them into either liquid or non-liquid. Consequently, it was possible to estimate the effects of the accounting analysis in 2005, divided into liquid and non-liquid accounts on deferred tax by checking R2 of regression analysis of each year. The result of demonstrative analysis supports the hypothesis that the value-relevance of corporation is to be increasing when the accounting method of firms classifies assets and liabilities associated with deferred tax into liquid and non-liquid. To add to this, it is still in favor of the hypothesis, although considered with meaning of actual analysis in terms of scale of firms and industrial categories(A dummy variable of median for basic asset's log) again. In conclusion, this research has an expanded meaning than former case studies by showing actual proof which shows the effect of change of standards and implementation focused on IFRS.
