This study investigates the market reaction to the second revision of the consolidation tax. The empirical results show that, on average, the construction industry has a negative market reaction on the important event dates of the second revision of the real estate integration tax. However, the results show that companies with high asset stocks and debt ratios do not have significant market reactions on the critical event dates of the second revision of the combined real estate tax. The empirical results of this study can provide regulatory agencies to understand the impact of the new real estate taxation system on my country's capital market.
