Tax exhaustion effect hypothesis says that firms with low expected marginal tax rates on their interest deductions employ less debt in their capital structure. We use logit analysis to study how financing decision is related to tax after controlling non tax effects. We treat non debt tax shields as proxy of marginal corporate tax rates which affect the probability of using the deductibility of debt tax shields and empirically test the tax effect on financing decision in Korea. In conclusion, we provide evidence that debt financing is positively related to tax in the former sub-period. This results partially support for tax exhaustion effect hypothesis and low tax rate firms have lower debt levels than high tax rate firms.

There has been considerable controversy over the impacts of the tax credit on R&D expenditures in many countries. Korea has adopted various kinds of tax credit system to stimulate private firm' R&D expenditures. Korean government, Recently, is trying to reform tax system to reduce tax credit programmes according to Uruguay Round agreement and in line with OECD policy standards. The purpose of this paper is to analyze the effectiveness of current tax credit system on technology innovation in Korea and derive some policy implications over tax reform. In this paper, firstly, I investigate the size of tax reduction effects from each program in theoretical models and simulate the actual rate of individual tax incentive to a unit of R&D expenditure. I find that theoretically the reserve fund for technology development program has given the largest tax reduction effects to private firms irrespective of the R&D incentive system reform. Tax credit on R&D expenditure also has been very effective instrument to firm's tax reduction. Secondly, I try to measure the effectiveness of tax credit through the estimation of effective margianl tax rate between with the system and without the system of credit on R&D expenditure during the tax credit reform periods. I find that the tax credit on R&D has lowered firm's investment cost since the system introduced. I also have strong results that there has been a positive relation between the fluctuation of firm's R&D expenditure and the change of effective marginal tax rate. I suggest that it is better to sustain the system of tax credit on R&D for a while to increase firm's R&D expenditure.

The purpose of this study is to investigate factors that affect corporate CEOs' tax avoidance, ultimately helping find how to fundamentally prevent the avoidance, establish a tax system that ensures tax payers' compliance and revise tax laws and regulations in a positive way. For the purpose, this researcher surveyed corporate CEOs with a questionnaire that contained many questions of various types, which was developed based on previous studies. Findings of the study can be summarized as follows. Main factors affecting tax avoidance were the application of tax provisions, the ability to understand tax laws and the expectation of tax avoidance. The more corporate CEOs' were influenced by the first and the third factors, the higher their propensity for tax avoidance was. On the contrast, corporate CEOs were lower in propensity for tax avoidance when they were more able to understand tax laws. Regarding the three factors' relative influences, tax avoidance was most affected by the expectation of tax avoidance, followed by the ability to understand tax laws and the application of tax provisions in order. Meanwhile, a multi-regression analysis using the sequential deletion technique showed that tax avoidance were affected by the application of tax provisions and the expectation of tax avoidance and that tax avoidance was most influenced by the application of tax provisions, followed by the expectation of tax avoidance. These findings indicate that the degree of corporate CEOs' tax avoidance may vary depending on social and environmental changes that their business face. Meanwhile, positive factors such as tax-bearing capacity and the procedure of tax calculation and negative factors such as management ethics and tax authorities' regulation are all thought to be not helping prevent tax avoidance.

On January 1, 2020, the liquor tax for beer and takju was reorganized from the ad valorem tax to the specific tax. The purpose of the reorganization of the liquor tax announced by the National Tax Service is to improve the quality of the liquor and to resolve unreasonable discrimination between domestic and imported liquor. However, it is necessary to determine whether the National Tax Service's standard for levying the liquor tax is appropriate for the purpose. In this study, the change in the liquor industry is estimated due to the reorganization of the liquor tax using Hicks net price elasticity. In addition, the specific tax for each of the liquors and the alcohol content derived from the social cost minimization model is compared. The main findings are as follows. First, when the liquor tax of beer and takju is converted to the specific tax, social costs increase, and social welfare decrease. Second, if all the liquors are converted to the specific tax, social costs decrease. Third, when comparing specific tax by each of the liquors and the alcohol content according to the social cost minimization model, The specific tax by alcohol content can be considered more appropriate in terms of social cost and the stakeholders in the liquor industry.

In Vietnam, tax compliance has become an important goal in the tax reform strategy. In the context of technology 4.0, the application of the electronic tax system is of great significance to small- and medium-sized enterprises (SMEs). The paper explores factors influencing electronic tax compliance of SMEs in Vietnam. Data from 402 SMEs, who are business taxpayers, was selected through a researcher-designed questionnaire survey method. The results indicate that four groups of factors have significant effects on electronic tax compliance among Vietnamese SMEs. These groups include Taxpayer Awareness (TA), Perceived Ease of use (PTE), Vietnamese tax administration (VTA,) and Efficiency of Vietnamese tax policy (VTP). The factor analysis was adopted; Cronbach's alpha coefficients were calculated, exploratory factor analysis (EFA) was used. The findings found that among these four groups, the most influencing factor is taxpayer awareness. It is suggested that the Vietnamese government should pay attention to promote and support SMEs to raise full awareness of tax obligations. This could be done through various methods such as conducting workshops for updating tax policies and short courses to business taxpayers of electronic tax compliance. The study is expected to provide some important implications for policy-makers and practitioners in tax policy reform in Vietnam.

This paper analyzes the penalty tax system under the Customs Act of Korea and examines whether the penalty tax provision violate the constitutional principle of proportionality when imposed on a person who does not made import declaration intentionally or travelers who has not been made an import declaration of their carry-on items. It examines the provisions that adopt a penalty tax as a means to secure the effectiveness of the customs law. In relation to penalty tax, the case studies of the Supreme Court and Constitutional Court of Korea are analyzed by major issues such as the legal nature of the penalty tax, whether the penalty tax is unconstitutional, and the reasons for exemption from the penalty tax. There is no reasonable basis for the high penalty tax imposed on travelers' carry-on items for which import declaration has not been made. It is necessary to unify the penalty tax imposed when an import declaration is not made and the penalty tax on traveler's carry-on items. It is necessary to establish a limit on penalty tax and to create new regulations to exempt or reduce penalty tax when punished by administrative punishment to avoid double jeopardy. It is necessary to effectively secure the effectiveness of the Customs Act by converting the penalty tax into civil penalty that does not presuppose the faithful and accurate performance of tax obligations by the taxpayer. The government revised the penalty tax system in the Customs Act in 2019, but there are still many types of penalty tax and there are elements that are unconstitutional. It seems that the Korean government should lower the burden on the people by improving the system for the penalty tax system.

This study investigates the determinants of the likelihood of a tax re-audit in Korea. It adopts a researcher-administered questionnaire survey method for data collection. The survey questionnaire is randomly distributed to 1,120 individuals with tax-related knowledge and experience. Using a final sample of 342 responses, we conduct a cross-sectional regression analysis to test our hypotheses. The results show that the level of tax non-compliance significantly affects the likelihood of a tax re-audit. This finding suggests that the increase in re-audits in Korea is attributable to the tendency of the tax authority to conduct a re-audit to detect taxpayers' non-compliance behavior by excessively broadening the scope of re-audits. This study also finds that the level of tax non-compliance is influenced by the perception of procedural unfairness, measured by operational inconsistency and regulatory lack of clarity. Lastly, the results reveal that the level of tax non-compliance mediates the relationship between the perception of procedural unfairness and likelihood of a tax re-audit. This finding indicates that enhancing procedural fairness could fundamentally reduce unnecessary re-audits that infringe on the rights of taxpayers, as the likelihood of a tax re-audit is not solely determined by the level of tax non-compliance but also by perceived procedural fairness.
