Governments run on taxes, which is one of the major means of capital generation for a state. The state imposes income tax on income generated by individuals or businesses within their domain. Income tax helps in funding public services, providing goods for citizens, and paying government obligations. Income taxes vary from country to country, where income taxes are inquired by the federal government and state governments. Income taxes are of two types including personal income tax and corporate income tax. Personal income tax applies to an individual’s salary, wage, and other types of income. While, corporate tax is levied on corporations, businesses, partnerships, and the self-employed.
Global Tax Competitiveness
The COVID-19 pandemic changed the dynamics of global economies. Many countries adopted temporary changes to their tax systems during the COVID-19 period. Countries including the United States and France have reduced their corporate income tax rates by several percentage points. On the other hand, Colombia has increased its corporate income tax rate. Among the OECD countries, Portugal has improved its corporate tax base, while Belgium’s corporate tax base has been made less competitive. The United States, the United Kingdom, and Chile are discontinuing temporary improvements to their corporate tax bases.
The country’s tax code structure is a key factor that determines its economic performance. A well-structured tax code provides an easy gateway for taxpayers to apply tax policies and promote economic development through their taxes. According to the Tax Foundation, marginal tax rates on individual and corporate income have dropped significantly across the Organisation for Economic Co-operation and Development (OECD) over the past few decades. Most of the OECD countries generate a large amount of revenue from broad-based taxes such as value-added taxes (VAT) and payroll taxes. Taxes are hard to collect in the countries with highest wealth inequality due to the complex economy and taxation system.
Estonia is ranked number one among the OECD countries with the best tax code for a straight tenth year, according to the Tax Foundation’s International Tax Competitiveness Index. Estonia has a 20% tax on both corporate income and individual income, respectively. Latvia has the second most competitive tax system, which has adopted the Estonian system for corporate taxation. Latvia also has an efficient taxing system for labor income. Following Estonia and Latvia, New Zealand, Switzerland, Czech Republic, Luxembourg, and Turkey are among the top countries with the most efficient and competitive tax systems. Estonia has a competitive tax score of 100, while Latvia, New Zealand, Switzerland, Czech Republic, Luxembourg, and Turkey have competitive tax scores of 88.5, 86.1, 84.7, 81.2, 78.9, and 78.6, respectively. On the contrary, Colombia, Italy, France, and Chile have the least competitive tax systems having competitive tax scores of 46.4, 48.4, 49.1, and 50.5, respectively.
