What is the primary aim of a tax system based on equity?

The primary aim of a tax system based on equity is to ensure fairness in tax contribution. Equity in taxation refers to the principle that individuals should contribute to government revenue in a manner that is fair and just, based on their ability to pay. This principle is often divided into two aspects: horizontal equity, which suggests that individuals with similar ability to pay should contribute the same amount, and vertical equity, which states that those with greater ability to pay should contribute more.

When a tax system is designed with equity in mind, it strives to reduce the disparity between different income levels, ensuring that the tax burden is proportionate to individuals' financial capabilities. This promotes social justice and helps to address inequality within society, as those with lower incomes are not disproportionately burdened by taxes compared to those who are more affluent.

Other objectives, such as minimizing taxation for wealthy individuals or maximizing government revenue, do not inherently focus on fairness and can lead to inequities in the tax system. Simplifying tax legislation, while beneficial for practicality and compliance, does not directly relate to the equity of tax contributions. Therefore, ensuring fairness in tax contributions stands out as the fundamental aim of an equitable tax system.
