This study aimed to determine the changes in the local fiscal structure brought about by the change in the transaction tax, including the acquisition tax, by the central government. The review of the analysis results proved the following. First, the government's transaction tax exemption policy effectively influenced the expansion of the local fiscal budget. Transaction tax exemptions such as acquisition tax exemptions would not contribute to the expansion of the local fiscal budget in the short run, but may do so in the long run. Second, the review of the effect of the transaction tax exemption policy by the central government on the local fiscal structure confirmed that its impact on the local fiscal structure may vary depending on the timing of such tax exemption. Third, the overall local fiscal structure as a result of the transaction tax exemption by the central government was confirmed to have been influenced more by the fiscal capability of the local government than by the income level of the local residents. In conclusion, the stimulation of real estate transactions using tax tools may positively influence the overall fiscal structure of local governments, but it would also put pressure on the fiscal management of local governments because it is largely influenced by the fiscal capability of the local governments.

This study verifies whether the sustainable tax strategy provides unique information on earnings persistence and brings about the difference of value relevance of accounting information. Sustainability is measured by the 5-year coefficient of variation in cash ETR, such as in McGuire et al.(2013), which measures variability in long-term performance of tax avoidance. The value relevance of accounting information in this study is modified by the Ohlson model(1995), which explains the value of the firm by using accounting information such as net assets and net income and other non-accounting information. The samples of this study are the firms listed on the securities market from 2004 to 2015 and the final samples are 3,133 firm-year. The results of this empirical analysis show that the value relevance of accounting information increases as firms have long-term and sustainable tax strategies. Most of the prior studies on tax strategies have examined the tax minimization strategy that minimizes the tax cost. However, this study is different in that the sustainability of the tax strategy affects the value relevance of accounting information. The results of this study will be useful for the users to make decision using the value relevance of accounting information.

This paper suggests O(n²) polynomial time heuristic algorithm for corporate tax structure optimization problem that has been classified as NP-complete problem. The proposed algorithm constructs tax tree levels that the target holding company is located at root node of Level 1, and the tax code categories(T_e) 1,4,3,2 are located in each level 2,3,4,5 sequentially. To find the maximum tax-relief path from source(S) to target(T), firstly we connect the minimum witholding tax rate _minr_w(u, v) arc of node u point of view for transfer the profit from u to v node. As a result we construct the spanning tree from all of the source nodes to a target node, and find the initial feasible solution. Nextly, we find the alternate path with minimum foreign tax rate _minr_fi(u, v) of v point of view. Finally we choose the minimum tax-relief path from of this two paths. The proposed heuristic algorithm performs better optimal results than linear programming and Tabu search method that is a kind of metaheuristic method.

The Earned Income Tax Credit (EITC) is a policy that supports low-income households financially as well as provides an economic incentive to participate in the labor market. Thus, estimating the causal effect of the policy on the labor force participation rate of low-income households is critical for the policy evaluation. In this paper, we exploit the variation in the eligibility to the EITC and the size of the benefit over several reforms of the EITC in South Korea since 2008 and estimate the impact on the participation in the labor market. Using data from four major household surveys, we find that the results are mixed; in some samples and specifications, we find that the effect is positive and statistically significant, while it is insignificant in others. The estimated effect is more likely to be positive and significant when we restrict the sample to the period before 2014. It is an important topic of future research whether the EITC's effect gets weaker because it is extended to cover the self-employed and beneficiaries of the National Basic Livelihood Security.

This study aims to investigate whether and why the disclosure of full financial information to estimate taxable income (TI) is incrementally useful for investors' decision making at earnings announcements. This paper shows analytically that the information content of TI beyond book income is determined by the relative informativeness of TI exceeding that of book-tax differences (BTDs), and therefore should be affected by the earnings quality of TI relative to BTDs. This study collects data on earnings announcements from Korean listed firms and employs multiple regression tests for earnings persistence, a major indicator of earnings quality, of TI and BTDs and their information content. The empirical test results show that TI is more persistent than BTDs for the entire sample in this study. Further, the investors' reaction to TI is greater than that to BTDs, and the market response to TI controlling for BI is positive. However, the market test results are significantly observed only in the subsample group with full disclosure of financial statements, not in the samples with disclosure of aggregated earnings only. In sum, this study provides new evidence that the TI information obtained from a detailed earnings announcement is useful for investors in addition to book income.

This study suggests the direction to narrow down the difference between financial and tax accounting in relation to borrowing costs. Accounting for capitalization of borrowing costs under accounting standards for non-public entities should be revised to converge into KIFRS. The provision of corporate income tax law relating to capitalization of borrowing costs should be applied on the optional basis rather than compulsory application especially for non-public entities. The range of qualifying assets for capitalization under the tax law should be reviewed to comply with KIFRS.

Purpose - Utilizing a large sample of Korean firms, this study examines international diversification impacts on corporate tax avoidance and whether firms affiliated with large business groups (known in Korean as "chaebol") reinforce the relationship between international diversification and tax avoidance. Design/methodology - This paper hypothesizes that 1) international diversification is likely to increase tax avoidance, 2) the positive effect of international diversification on tax avoidance is likely to be more pronounced for chaebol firms. We examine the hypotheses by using Korean firms listed in the Korean stock market between 2011 and 2016. We employ the number of foreign subsidiaries and the entropy index as proxies for international diversification and CASH ETR and GAAP ETR as proxies for tax avoidance. Findings - Our findings are summarized as follows. First, we have found that as firms are more internationally diversified, tax avoidance increases. It means that international diversification can be employed as a method of reducing the tax burden. Second, firms affiliated with chaebol are strengthened by the positive relation between international diversification and tax avoidance. It is interpreted that chaebol firms have more effective opportunities to reduce taxes than other firms. When entering foreign markets, they can share experience and resources to decrease taxation within the large business group. Originality/value - This study provides empirical evidence regarding the tax effect of international diversification. Unlike prior studies, international diversification is positively related to tax avoidance in Korea. In addition, we present additional evidence on the chaebol effects of international diversification on tax avoidance, in which they have an advantage to reduce taxes using transfer pricing through related party transactions, income shifting to low tax rate countries, and establishing subsidiaries in tax havens.

This paper examines the effect of redistributive inheritance tax on income distribution and social welfare. The model used here is the Overlapping-Generations Model consisting of individuals with different bequest motives where the lifetime income distribution in each cohort is determined endogeneously by the dynamic bequest process. It is shown that the introduction of redistributive inheritance tax can improve the vertical equity in the sense that the increase in tax rate reduces the coefficient of variations of intra-cohort income distribution in steady-state. However, it is also shown that, the effect on social welfare, when measured by Benthamite SWF, is uncertain in general. The numerical simulations show that, in spite of its equity-enhancing effect, the tax increase can actually lower the steady-state social welfare within the plausible range of parametric values, through the long-run output effect as well as the deadweight welfare loss incurred by tax distortion. Hence, the problem of equity-efficiency trade-off can arise in this case. However, if both the market interest rate and the elasticity of marginal utility in individual's preference function are sufficiently high, it is shown to be possible that the steady-state social welfare is enhanced by the introduction of inheritance tax.

This paper examines the redistributive potential of capital taxations within the two-class overlapping generations model, where only capitalists are intergenerationally linked through heritable capital stocks. In particular, the dynamic welfare incidence of two different capital taxations is examined; first a capital income tax levied uniformly on interest earnings, and second, an estate tax levied on the intergenerational transfers of capital stock within the capitalists' families. Redistributive effects are measured by examining how the permanent and unanticipated changes in proportional capital income tax and estate tax rates affect workers' welfare when the proceeds in each period are distributed, in a lump-sum fashion, among young workers. It is shown that, except for in the short run, both the capital taxes are ineffective and may actually lower the workers' steady state welfare through the shifting of tax burden toward workers from capitalists. Differential incidence analysis shows that redistributive potential is diminished further when the lump-sum transfers are financed by the estate tax rather than by the capital income tax. Although the model examined in this paper is based on simple and strong assumptions, this study suggests that redistributive policy using the capital taxations may only have distortionary effects in the long run, without improving workers' welfare, by incurring dead-weight loss unless additional fiscal measures are implemented to increase the investment incentives.

This study examines the status quo of the support system for companies of persons with disabilities in Korea, and then estimates the corporate income tax reduced from a special taxation system, same as one applied to social enterprises and standard workplace for persons with disabilities, using 「Data for registered companies of persons with disabilities」(2020.6) by the Disable Enterprise Business Center. Now companies of persons with disabilities have more than 87% in the business continuity rate, and their employment rate of the average rate for 2015-2017 is higher than public institutions and private companies, which is in line with the government's employment promotion policy for the disabled. However, article 14 (Support in Taxation) of the 「Act On The Facilitation Of Entrepreneurial Activities Of Persons With Disabilities」 is still declarative and optional. Meanwhile, the corporate income tax reduced by a simulation method was calculated to be about KRW 130.1 billion for 5 years (KRW 26.02 billion per year). In this context, when comparing the tax revenue to be reduced with a positive effect by securing the effectiveness of Article 14, it can be said that the tax support for companies of persons with disabilities is feasible.
