The value of tangible assets depreciates over their useful life and this depreciation should be adequately reflected in any tax or financial reports. However, the method used to calculate depreciation can impact the financial performance of solar projects due to the time value of money. Korean tax law stipulates only one method for calculating the depreciation of solar photovoltaic facilities: the straight-line method. Conversely, USA's tax law accepts other depreciation methods as solar incentives, including the modified accelerated cost recovery system (MACRS) and Bonus depreciation method. This paper compares different depreciation methods in the financial analysis of a 10 MW solar system to determine their effect on the financial results. When depreciation was calculated utilizing the MACRS and Bonus depreciation method, the internal rate of return (IRR) was 10.9% and 16.4% higher, respectively, than when the Korean straight-line depreciation method was used. Additionally, the increased IRR resulting from the use of the two US methods resulted in a 20.5% and 27.4% higher net present value, respectively. This shows that changing the depreciation calculation method can redistribute the tax amount during the project period, thereby increasing the discounted cash flow of the solar project. In addition to increasing profitability, USA's depreciation methods alleviate the uncertainty of solar projects and provide more flexibility in project financing than the Korean method. These results strongly suggest that Korean tax law could greatly benefit from adopting USA's depreciation methods as an effective incentive scheme.

The purpose of this paper is to come up with the measures for sustainable development of the agricultural sector in store for the strengthened U.N. Framework Convention on Climate Change. We analyze the spillover effects of Methane and Nitrous Oxides taxes (carbon tax) on the Korean agricultural sector. Unlike the other sectors, the agricultural sector has a unique characteristic generating greenhouse gas in the process of production itself even without consuming much fossil fuel. In order to estimate the impacts of those taxes, non-linear optimization method has been used with various assumed scenarios. The production effect, income and' price effect, and greenhouse gas emission reduction effect in the agricultural sector have been estimated through this method. The empirical results show that the paddy sector has a bigger tax effect than the livestock sector. In the paddy sector, the carbon tax has more impacts in the suburban areas than in the rural areas, while the swine farming section in the livestock sector has a conspicuous income effect in the midst of low greenhouse gas emission effect. These results allude us to apply graded tax rates to the crop, the livestock, and the region of different kind. Even if the agricultural sector has a less tax effect when compared with other industrial sectors, an environmental tax might be an effective measure to prevent global warming.

This study examines empirically the significant changes in tax payments when the consolidated tax return is introduced in the future. We estimate the consolidated tax payments under the eight cases which are classified as such : whether only 100% ownership subsidiaries should be included or 80% and over, whether all subsidiaries should be included or only subsidiaries with loss, and whether unrealized profits from intercompany transactions should be excluded or not. After estimating the consolidated tax payments, we test the difference between the consolidated tax payments and the sum of the individual tax payments of the subsidiaries. The results of the test show that the consolidated tax payments are significantly less than the sum of the individual tax payments of the subsidiaries. We interpret that the inclusion of the losses of the subsidiaries in the consolidated tax base makes the tax payment decrease. Based on our analysis about 3.8 billion Won per each parent company would decrease due to the introduction of the consolidated tax return. And we find that under the mandatory consolidated tax return system the significant difference between the consolidated and individual tax payment exists except that the only 100% ownership subsidiaries are included and unrealized profits from intercompany transactions are not excluded. However, when the parent companies have the discretion to select the consolidated subsidiaries, the consolidated tax payments are significantly less than the sum of the individual tax payments of the subsidiaries regardless of the ownership percentage, inclusion of the loss of the subsidiaries and exclusion of the unrealized profits.

Construction equipment has applied to depreciation over the years, however, the price index for construction equipment is not properly reflected in existing quantity per unit and the local tax law. Thus, this study shows the analysis of the corporate tax law, the local tax law and business accounting standards, characteristics of the domestic depreciation system and depreciation methods, and the capital recovery factor of construction equipment applying the theory for economic efficiency. It also presents cases of depreciation on the basis of quantity per unit and tax law using straight-line depreciation method and declining balance method. It is proposed that the relations of the application system of permissible period for construction equipment and the existing system be explained and the application system of permissible period for construction equipment be imposed. Furthermore, it proposes the development of depreciation tables of construction equipment monthly expenses based on the domestic price index and applications. In addition of that, it proposes the analysis of pros and cons of the methods suggested and application limits of the study and subsequent improvement plans. This study should reflect more rational and objective reality in quantity per unit and tax law.

A new base expense .system is implemented to substitute the standard income ratio system which has been used for more than 50 years. A base expense system requires a rigorous documentary evidences of important expenses such as purchase cost, labour cost, or rent. In order to make a successful tax savings, it is necessary to know the critical factors affecting tax payment in a base expense system. In this article, operating mechanisms of the base expense system and tax strategy under this system are introduced. If base expense system is successfully implemented, it will contributes considerably to progress in inducing tax compliance of non book keeping professionals who earn relatively high income in Korea.

The purpose of this paper is to estimate the revenue function of the personal income tax of Korea. Unlike the traditional approach employing the data adjustment, this paper explicitly includes the explanatory variables of the tax rate or schedule in the revenue function and further estimates the functions by income sources such as labor, interest, global, and dividend incomes. One of the main findings is the GNP elasticity of the combined personal income tax is around 1.2 when evaluated on the basis of the estimates of the GNP elasticities of tax revenue from respective income sources, which is somewhat smaller than those in the previous studies. Another interesting result is that the GNP and interest rate elasticities of the interest income, are found around one and .15 respectively, as expected. Also, the estimate of the tax-free income coefficient is significantly negative in the labor income tax revenue function.

This study examine the effects of changes in the dividend income tax rates, the corporate dividend policy, and the ownership structure on the stock valuation. The empirical findings indicate that : (1)firm's ownership structure is positively correlated with stock return ; (2) the interaction of firm's ownership structure and the dividend policy is positively correlated with stock return ; (3) the interaction of the changes in the dividend income tax rates and dividend policy is correlated with stock return ; (4) the interaction of the changes in the dividend income tax rates and firm's ownership structure is correlated with stock return ; (5) the interaction of the increases in the dividend income tax rates, firm's ownership structure, and the dividend policy is positively correlated with stock return. This suggests that non-taxing of capital gains provide tax shelters to individual investors and investors prefer non-taxing income to dividend income.

There has been some controversy about imposing income tax on the compensation for university employees' inventions. In this research, various issues of taxation related to such compensation are examined, with Supreme Court Judgement 2014Du15559 as a means of understanding the confusion associated with this taxation. An amendment of the Income Tax Law is proposed based on the examination results, in order to promote research in the university field, which is able to make various types of compensation for employee inventions fall into the category of tax exemptions. It is concluded that if the Income Tax Law is amended to refer to the definition of technology in the Technology Transfer and Commercialization Promotion Act, instead of that of the Invention Promotion Act, the compensation resulting from newly emerging IPRs and technical know-how, which are currently taxed, can become tax exempt.
