Tax Equity: Videos & Practice Problems

Tax equity is a crucial concept in designing a fair and efficient tax system, focusing on how the tax burden should be distributed among individuals. It addresses questions of fairness and the principles that guide tax contributions. Two primary principles of tax equity are the benefits principle and the ability to pay principle.

The benefits principle posits that individuals should pay taxes in proportion to the benefits they receive from public services. For instance, a gasoline tax exemplifies this principle: the revenue generated is used to maintain and repair roads, benefiting those who drive. Similarly, a marina tax funds the upkeep of waterways, with boat owners contributing based on their usage. This principle ensures that those who utilize specific services are the ones funding them.

In contrast, the ability to pay principle suggests that tax contributions should be based on an individual's financial capacity. This principle advocates for a progressive tax system where wealthier individuals contribute a larger share of their income compared to those with lower incomes. For example, if a person earning $10,000 pays $1,000 in taxes (10%), they are left with $9,000 in disposable income. Conversely, someone earning $50,000 who pays the same $1,000 in taxes only contributes 2% of their income, retaining $49,000 in disposable income. This disparity illustrates that higher earners can afford to pay more without significant sacrifice, supporting the notion that taxes should be levied more heavily on those with greater financial means.

These principles lead to the concepts of vertical equity and horizontal equity. Vertical equity emphasizes that individuals with higher incomes should pay more taxes, reflecting their greater ability to contribute. On the other hand, horizontal equity asserts that individuals in similar economic situations should pay the same amount in taxes. This raises ethical considerations, as seen in the example of two families with different financial burdens—one facing high medical expenses and the other incurring significant tuition costs. Determining which family deserves a tax break highlights the complexities of achieving horizontal equity in tax policy.

Understanding these principles is essential for evaluating tax systems and ensuring they are designed to be both fair and effective. The next step involves exploring the three types of taxes: regressive, proportional, and progressive, which further illustrate how tax systems can be structured to align with these equity principles.

Tax systems can be categorized into three main types: regressive, proportional, and progressive, each with distinct implications for tax equity and the amount of taxes paid as income increases.

A regressive tax system features decreasing tax rates as income rises. For example, an individual earning $50,000 might pay a tax rate of 20%, while someone earning $100,000 pays 15%, and a person making $200,000 pays only 10%. To calculate the taxes paid, you multiply the income by the tax rate. Thus, the taxes paid would be:

For $50,000: $50,000 × 0.20 = $10,000

For $100,000: $100,000 × 0.15 = $15,000

For $200,000: $200,000 × 0.10 = $20,000

Even though the percentage decreases, the total tax paid increases with income, illustrating a potential inequity where higher earners pay a lower percentage of their income in taxes.

In contrast, a proportional tax system maintains a constant tax rate regardless of income level. For instance, if the tax rate is set at 15%, the calculations would be as follows:

For $50,000: $50,000 × 0.15 = $7,500

For $100,000: $100,000 × 0.15 = $15,000

For $200,000: $200,000 × 0.15 = $30,000

Here, as income increases, the total tax paid also increases, reflecting a straightforward relationship between income and tax liability.

The progressive tax system is designed to impose higher tax rates on higher income brackets. For example, an individual earning $50,000 might pay 10%, while someone earning $100,000 pays 15%, and a person making $200,000 pays 20%. The calculations would be:

For $50,000: $50,000 × 0.10 = $5,000

For $100,000: $100,000 × 0.15 = $15,000

For $200,000: $200,000 × 0.20 = $40,000

This system aligns with the principle of tax equity, as those with greater financial means contribute a larger share of their income, while still retaining significant disposable income after taxes.

Understanding these tax systems is crucial for grasping the broader concepts of tax equity and the ability to pay, which emphasize that higher earners should contribute more to support public services while maintaining their financial well-being.
