There are many different taxation systems in the world, reflecting historical, cultural, and economic impacts on taxation. These different taxation systems influence how the government collects money and uses it. There are three main tax systems that differ in how they are applied to income and consumption: progressive, regressive, and proportional.
In a progressive tax system, tax rates increase as income increases, making sure higher income makers pay a larger percentage of their income through taxes. This system is meant to show equity and redistribute wealth to the poorer ones, trying to close the gap in income. Countries that use the progressive tax system include the United States and other European countries such as Germany. In the United States, individuals with higher incomes can pay as much as 37% federal tax, while people who earn lower pay less of a percentage. However, critics argue that this system might discourage productivity and innovation at higher income levels.
In regressive tax systems, taxes are placed opposite of a progressive tax. Lower-income individuals take the burden on taxes because everyone takes a larger percentage of income from low income groups than high income groups.. Examples of regressive taxes are sales taxes and excise taxes. For example, a 10% sales tax on groceries would be harder on low income than high income families because it is a bigger portion of the lower income family’s money. Countries who use this system, such as Brazil, are often criticized for negative impacts on the lower income populations.
In a proportional tax system, the same tax rate is inflicted on all income levels. These are also known as flat taxes, because everyone is assigned a flat rate of tax. For example, in Estonia, all income earners are taxed at 20%. Supporters of this system believe that proportional tax systems simplify compliance while encouraging economic growth to equality. However, a proportional tax system lacks redistributive effects of progressive taxes, potentially worsening income inequality.
Today, taxation has introduced many challenges around the world present in many countries. Tax evasion is an illegal act of lying about income or hiding assets. This results in the deprivation of significant amounts of government revenue. Tax avoidance is legal, where people exploit loopholes to minimize tax liabilities. Tax avoidance is often used by large corporations who use complex strategies to shift profits to low tax payments, reducing their tax burdens. Additionally, tax havens are another method to try and avoid tax systems. Countries such as Luxembourg and the Cayman Islands often get attention from wealthy and huge corporations because they don’t collect taxes. This often deprives the other nations of necessary revenue. Efforts have been made to reduce tax havens through global agreements like the OECD’s Base Erosion and Profit Shifting (BEPS) initiative, which aims to prevent profit shifting and ensure companies pay taxes where they generate value. Additionally, tax enforcement has become more difficult due to the increase in e-commerce and cross border purchases. This can be highlighted through the tension between US and the European Union over digital service taxes. To address the rising international challenges, organizations such as the OECD and the G20 have been established to promote international cooperation and fair taxation.
Multiple case studies show how diverse taxation reflects societal priorities. United States and European taxation models differ vastly - the US primarily relies on progressive income taxation and payroll taxes to fund programs, whereas European countries such as Sweden and Denmark use a combination of high progressive income taxes and the VAT. For example, Sweden has one of the highest income tax rates in the world, but balances it with free healthcare and education, embodying the idea of high taxes with high benefits. Below, we will discuss some countries who show how taxation reflects society and priorities.
Sweden uses the Nordic model, where high taxes provide a strong welfare state. In Sweden, personal income tax rates exceed 50%, and the VAT applied is 25% for most goods and services. However, Swedish also enjoy free healthcare, generous parental leaves, and free higher education; this results in a greater trust in their tax system.
Singapore’s tax system has a much lower personal and corporate tax rate, never exceeding 22%. The government compensates for its low tax revenue through the Central Provident Fund - a mandatory savings organization for healthcare and retirement. Singapore’s model aims to promote economic growth while maintaining discipline.
The United Arab Emirates (UAE) has a very unique tax system - it has no income taxes. Instead, their government relies on oil revenue and consumption taxes such as the VAT to generate revenue. This economy attracts businesses, but it also raises concerns about the long term sustainability with a system like this as the modern world is transitioning away from fossil fuels.
Tax systems worldwide show a balance between equity, efficiency, and economic priorities. Regardless of the system type, each impacts a citizen’s lives in many ways. Global challenges highlight the need for international collaboration in order to foster fairness and create efficiency policies. Each country has a different way of taxing depending on its historical and societal context, making each country unique. As economies evolve, their tax systems will shift to adapt to different needs in a globalized and interconnected world.
