Pajak Kekayaan, Alternatif Sumber Penerimaan Pajak di Indonesia Merespons Pandemi Covid-19

In response to the decline in tax revenue due to the Covid-19 pandemic, the government has issued a regulation to collect a new tax, namely the Carbon Tax through Law Number 7 of 2021 concerning Harmonization of Tax Regulations. Because this Carbon Tax is being implemented for the first time in Indonesia and its calculation is also not simple, it is estimated that the successful collection of it will take a long time. Whereas the need to explore new sources of tax revenue is needed at this time in the short term to cope with sharply increasing expenditures in order to overcome the medical and social impacts of the Covid-19 pandemic. The government could consider implementing a Wealth Tax in addition to existing taxes including the Carbon Tax. Wealth Tax in addition to increasing tax revenues can also be used as a means of redistribution of wealth in order to reduce the wide gap between the rich and the poor. The proposed Wealth Tax is a Wealth Tax that is levied only once, intended for individuals, with a threshold as well as Non-Taxable Wealth (NTW) of Rp21,000,000,000.00 for unmarried taxpayers and Rp22,500,000,000.00 for marriage taxpayers, using progressive rates of 0.2%, 0.4%, 0.6%, and 0.75%, and can be repaid in installments for 5 years. The basis for imposition of Wealth Tax is net assets, namely the total assets minus the total liabilities reported in the Annual Income Tax Return (SPT) of the previous year's individual taxpayers minus the Non-Taxable Wealth (NTW). Using data on the wealth of the Indonesian population in 2018, it is estimated that thecollection of this Wealth Tax can generate additional tax revenues of around 0.83% of the Gross Domestic Product in 2020.

Mental accounting shapes public support for green spending of carbon tax revenues

Despite its potential for curbing greenhouse gas emissions, carbon taxation encounters strong public resistance in many countries. However, social acceptability of carbon taxation heavily depends on how the generated revenues are used. Citizens prefer carbon taxation schemes where tax revenues are earmarked for environmental protection rather than for non-environmental purposes (e.g., lowering the value-added tax or labour taxes). Here, we test the hypothesis that acceptability varies across earmarking domains according to a mental accounting heuristic, by which people create mental budgets where the origin of revenues is matched thematically with their domain of use. Across two experiments conducted in the United Kingdom and in France (Ntotal = 3500), we show that citizens display a specific preference for tax designs where the earmarking domain is matched with the revenue source (i.e. a carbon tax earmarked for environmental protection), relative to an unmatched tax scheme. Moreover, we find that acceptability of carbon taxation increases with the proportion of tax revenues earmarked for environmental protection.

Modelling the Transition towards a Carbon-Neutral Electricity System—Investment Decisions and Heterogeneity

To achieve the climate goals of the Paris Agreement, greenhouse gas emissions from the electricity sector must be substantially reduced. We develop an agent-based model of the electricity system with heterogeneous agents who invest in power generating capacity under uncertainty. The heterogeneity is characterised by the hurdle rates the agents employ (to manage risk) and by their expectations of the future carbon prices. We analyse the impact of the heterogeneity on the transition to a low carbon electricity system. Results show that under an increasing CO2 tax scenario, the agents start investing heavily in wind, followed by nuclear and to some extent in natural gas fired power plants both with and without carbon capture and storage as well as biogas fired power plants. However, the degree to which different technologies are used depend strongly on the carbon tax expectations and the hurdle rate employed by the agents. Comparing to the case with homogeneous agents, the introduction of heterogeneity among the agents leads to a faster CO2 reduction. We also estimate the so called “cannibalisation effect” for wind and find that the absolute value of wind does not drop in response to higher deployment levels, but the relative value does decline.

Conceptual approaches to improving carbon dioxid taxation in Ukraine

The domestic carbon tax needs to improve tax administration to ensure its fiscal efficiency and reduce transaction costs for tax compliance. Despite the fact that in the Tax Code of Ukraine the calculation of such a tax is based on the actual indicators of CO2 emissions, in practice it is based on the amount of resources consumed and the characteristics of the production process. Accordingly, the difficulties in administering this tax are the complexity of tax audits and the need to involve environmental experts. All this does not allow to adhere to the principle of cost-effectiveness of taxation and highlights the need to find opportunities to simplify the process of tax administration on the basis of world best practices. The purpose of the article is to outline conceptual approaches to improving carbon taxation, which will allow Ukraine to simplify tax administration and together with the EU to effectively combat the effects of climate change in order to increase security and create new opportunities for Ukrainian business under the European Green Deal. The methodological basis of the study was the use of a set of general and special methods: generalizations and scientific abstraction, historical and logical, extrapolations, spatial and graphical and tabular methods of visualization. The application of the SWOT analysis method and the systematization of European practice revealed that the most acceptable for Ukraine is the use of tax on CO2 emissions in the form of an indirect tax on energy consumption. Coefficients of carbon content in fuel, calorific value of fuel and its oxidation factor were used to convert the emission base carbon tax into the fuel base carbon tax. The implementation of these proposals will help increase the efficiency of administration of such a tax, as it will: 1) reduce the number of taxpayers through the introduction of the institution of tax agents while increasing the amount of tax paid by one taxpayer; 2) simplify the procedure for calculating the tax base by taxpayers and employees of tax authorities; 3) increase the fiscal efficiency of the environmental tax on carbon dioxide emissions from stationary sources by 50% in the case of setting the CO2 price at UAH 10 per ton (5-fold when setting the CO2 price at UAH 30 per ton in accordance with the proposals of the bill No 5600) and to attract potential revenues from the transport sector in the amount of 0.06% of GDP. The use of practical proposals and recommendations obtained in the article will increase the effectiveness of Ukraine's tax policy by forming a set of measures which will reduce the energy dependence of the national economy, including through incentives for energy-saving and climate-neutral technologies, reduce the burden on the environment, and will help simplify the administration of environmental taxes while increasing their fiscal efficiency. Research materials can be used in the preparation of draft regulations and policy documents in the field of environmental and excise taxation, which is within the competence of the Ministry of Finance of Ukraine, as well as in the formation of proposals, reservations and recommendations to other regulations on improving environmental and excise taxation initiated both by the authorities of the executive power of Ukraine, and the Verkhovna Rada of Ukraine on improving environmental and excise taxation. The theoretical results are the development of a general theory of fiscal administration for environmental and excise taxation.

The International Influence of the Emissions Trading System in Mexico

This article aims to give an overview of the international influence of the Emissions Trading System (ETS) in Mexico. It is divided into three parts. First, it briefly examines both the international Climate Change regime through the description of such instruments as the 1997 Kyoto Protocol and the 2015 Paris Agreement, and the national regime by reviewing as the 2012 General Law on Climate Change (LGCC), the National Emissions Registry (RENE) and its Regulations, as well as other instruments regarding mitigation from carbon tax and clean energy. Second, it analyzes the legal framework of the pilot phase of the ETS in Mexico (under the cap and trade principle) which seeks to reduce carbon dioxide emissions (CO2) only in the energy and industry sectors whose emissions are greater than 100 thousand direct tonnes of CO2. In doing so, it also explains the relevance of implementing an ETS as a cost-effective mitigation measure to achieve the Nationally Determined Contributions (NDCs) in order to reduce 22% greenhouse gas (GHG) emissions by 2030 (increasing to 36% if there is international support and financing) and 50% by 2050 as a developing country. Third, it focuses on the European Union Emissions Trading System (EU ETS) experience and shows that all its phases must be done gradually by adopting the learning-by-doing approach.
