2.2 Progressive tax system and marginal tax rates
3 min read•july 30, 2024
The and marginal tax rates play a crucial role in shaping income distribution and economic incentives. These concepts determine how much individuals pay in taxes based on their income levels, with higher earners typically facing steeper rates.
Understanding marginal tax rates is key to grasping how the progressive system works. As income increases, it's taxed at higher rates within specific brackets. This approach aims to balance fairness and economic growth while funding government operations and social programs.

Implications of Different Tax Systems
- Choice of tax system significantly impacts:
- Income distribution across society
- Economic incentives for work and investment
- Government revenue generation
- Progressive systems:
- Reduce after-tax income disparities
- May discourage high-income earners from additional work or investment
- Regressive systems:
- May disproportionately burden lower-income households
- Can lead to increased reliance on government assistance programs
- Proportional systems:
- Simplify tax calculations and administration
- May not adequately address societal needs for wealth redistribution
Marginal Tax Rates in Progressive Systems
Understanding Marginal Tax Rates
- Marginal tax rates represent percentage of tax applied to last dollar of taxable income within specific
- Increase as taxable income moves into higher tax brackets
- Differ from effective tax rates, which represent average rate of tax paid on total taxable income
- Calculation of marginal tax rates involves:
- Determining tax bracket for given income level
- Applying corresponding rate to additional income within that bracket
- Example: If marginal rate is 22% for 85,000 bracket, earning an additional 220 more in taxes
- Marginal rates support progressive nature of tax system
- Ensure higher-income earners contribute larger proportion of income in taxes
- Create step-wise increase in tax liability as income rises
Impact of Marginal Tax Rates
- Influence economic decision-making
- Affect after-tax return on additional income earned
- May impact choices regarding work hours, investments, or business expansion
- Crucial for tax planning strategies
- Help individuals and businesses make informed decisions about income timing
- Guide tax-efficient strategies (income shifting, deduction timing)
- Can create "" effect
- Occurs when inflation pushes income into higher tax brackets without real increase in purchasing power
- May lead to unintended tax burden increases over time
Income and Tax Burden in Progressive Systems
Relationship Between Income and Tax Burden
- Tax burden, measured as percentage of income, increases as income levels rise
- Higher-income taxpayers face larger absolute tax burden and higher effective tax rate
- Example: Someone earning 50,000 might pay 15% effective rate
- Use of tax brackets and graduated rates creates step-wise increase in tax liability
- Each additional dollar of income is taxed at the marginal rate for its bracket
- Results in smooth progression of effective tax rates as income increases
- Progressive structure aims to maintain vertical equity
- Those with greater ability to pay contribute more to government revenue
- Reflects principle of "ability-to-pay" in taxation
Factors Affecting Tax Burden Distribution
- Tax credits, deductions, and exemptions modify relationship between income and tax burden
- Can reduce progressive nature of system for certain taxpayers
- Examples: Mortgage interest deduction, child tax credit, charitable contribution deductions
- examines who ultimately bears economic burden of tax
- May differ from legal obligation to pay
- Example: Corporate taxes may be shifted to consumers through higher prices or to workers through lower wages
- Analysis tools for assessing impact on income distribution:
- graphically represent income distribution
- Gini coefficients measure income inequality
- Used to evaluate how tax system affects overall income distribution in society
Key Terms to Review (22)
Ability-to-pay principle: The ability-to-pay principle is a tax policy concept that asserts individuals should pay taxes based on their capacity to bear the tax burden, rather than the benefit received from public services. This principle aims to create a fairer tax system, where those with higher incomes contribute a larger share of their income, promoting equity in taxation. It serves as a foundation for designing progressive tax systems, which levy higher rates on higher income brackets, ensuring that taxpayers contribute in proportion to their financial means.
Bracket Creep: Bracket creep is the phenomenon where taxpayers find themselves pushed into higher tax brackets as their income rises, often due to inflation or wage increases, without any change in tax rates. This can lead to individuals paying a higher percentage of their income in taxes, even if their real purchasing power has not increased significantly. Essentially, bracket creep can create a disconnect between actual economic gain and the effective tax burden imposed on taxpayers.
Earned Income Credit: The Earned Income Credit (EIC) is a tax benefit designed to help low to moderate-income workers by reducing the amount of tax owed and potentially providing a refund. This credit encourages and rewards work by allowing eligible individuals to receive a significant financial boost, particularly benefiting families with children. It connects closely with the tax formula by affecting tax liability calculations, influences which tax forms are used to claim it, and interacts within the structure of the progressive tax system, where those with lower incomes can receive larger refunds.
Effective Tax Rate: The effective tax rate is the average rate at which an individual or corporation is taxed on their income, calculated as the total tax paid divided by total taxable income. This rate provides a clearer picture of a taxpayer's tax burden compared to marginal tax rates, as it considers all forms of income and applicable deductions. Understanding this concept is crucial for evaluating how different tax policies impact overall tax liability and for making informed decisions about filing status and financial planning.
Flat tax: A flat tax is a tax system that applies a single fixed rate to all taxpayers, regardless of their income level. This type of taxation simplifies the process of calculating taxes and is often seen as equitable since everyone pays the same percentage. It contrasts with progressive tax systems, where rates increase with higher income levels, and can also impact corporate taxation calculations in terms of how businesses structure their tax liabilities.
Gini Coefficient: The Gini Coefficient is a statistical measure that represents income inequality within a population, ranging from 0 (perfect equality) to 1 (perfect inequality). It helps to quantify how evenly or unevenly income is distributed among individuals or households, making it a crucial tool in evaluating the effectiveness and fairness of tax systems and policies aimed at reducing inequality.
Graduated tax system: A graduated tax system is a tax structure where the tax rate increases as the taxable income increases. This system is designed to ensure that individuals with higher incomes pay a larger percentage of their income in taxes compared to those with lower incomes, reflecting the principle of equity in taxation.
Internal Revenue Code: The Internal Revenue Code (IRC) is the body of federal tax law in the United States, enacted by Congress and designed to govern the assessment and collection of taxes. It serves as the primary source of tax legislation, detailing rules for income, deductions, credits, and various tax structures. The IRC is vital for understanding how taxes are computed, the rights of taxpayers, and the obligations of the Internal Revenue Service (IRS) in administering tax laws.
Lorenz Curves: Lorenz curves are graphical representations that illustrate the distribution of income or wealth within a population. They help visualize economic inequality by showing the proportion of total income earned by different segments of the population, allowing for a clear understanding of how evenly or unevenly wealth is distributed in relation to a perfect equality line.
Marginal Tax Rate: The marginal tax rate is the rate at which the last dollar of income earned is taxed, reflecting how much additional tax will be paid on each extra dollar of income. This concept is crucial for understanding tax liability and affects how individuals and businesses make financial decisions, from investments to spending. It's closely linked to the overall tax formula, principles of taxation, filing status, and the progressive nature of the tax system.
New Deal Tax Reforms: New Deal tax reforms refer to a series of changes made to the U.S. tax system during the Great Depression, primarily under President Franklin D. Roosevelt's administration, aimed at providing economic relief and recovery. These reforms introduced progressive taxation principles, increased marginal tax rates on the wealthy, and established taxes on corporate profits and inheritances, thereby redistributing wealth and enhancing government revenue to fund social programs.
Progressive Tax System: A progressive tax system is a tax structure where the tax rate increases as an individual's income increases, meaning those with higher incomes pay a larger percentage of their income in taxes. This system aims to reduce income inequality by imposing a heavier tax burden on wealthier individuals while providing relief to lower-income earners, reflecting the principle that taxpayers with greater ability to pay should contribute more.
Reagan Tax Cuts: The Reagan Tax Cuts refer to a series of tax reduction measures implemented during the presidency of Ronald Reagan in the early 1980s, aimed at stimulating economic growth by reducing individual and corporate tax rates. These cuts were designed within the framework of a supply-side economic theory, which posited that lower taxes would encourage investment, job creation, and ultimately lead to increased tax revenue through economic expansion.
Standard Deduction: The standard deduction is a specific dollar amount that reduces the income on which an individual is taxed, simplifying the tax filing process. It varies based on filing status and plays a significant role in calculating taxable income, as well as influencing the choice between standard and itemized deductions. Understanding how this deduction integrates with other aspects of the tax system is crucial for determining overall tax liability.
Tax bracket: A tax bracket is a range of income that is taxed at a specific rate, which is part of the overall income tax system. Understanding tax brackets is essential because they determine how much tax an individual or entity owes based on their income level, directly affecting their overall tax liability. As income increases, individuals may move into higher tax brackets, meaning they will pay a higher percentage on the additional income above a certain threshold.
Tax Burden: Tax burden refers to the financial impact of taxes on individuals or businesses, indicating how much of their income or profits are paid in taxes. This term encompasses both the direct costs of taxes and the indirect costs associated with compliance, economic distortion, and reduced disposable income. Understanding tax burden helps to evaluate the effectiveness and fairness of a tax system, especially in relation to concepts such as progressivity, equity, and overall efficiency.
Tax Cuts and Jobs Act: The Tax Cuts and Jobs Act (TCJA) is a significant piece of legislation enacted in December 2017 that overhauled the U.S. tax code, primarily aimed at lowering individual and corporate tax rates while altering various deductions, credits, and exemptions. The act has made substantial changes to the tax treatment of dependents, adjusted standard and itemized deductions, impacted the calculation of alternative minimum tax, and introduced new rules for depreciation and credits.
Tax Equity: Tax equity refers to the principle that the tax system should be fair, ensuring that individuals and businesses contribute to government revenue in proportion to their ability to pay. This concept is closely linked to the idea of fairness in taxation, where those with greater financial resources shoulder a larger share of the tax burden. It supports the structure of a progressive tax system, which applies higher tax rates to higher income levels, thereby fostering a more equitable society.
Tax Incentive: A tax incentive is a financial benefit provided by the government to encourage specific behaviors or activities among individuals or businesses, such as investment, saving, or spending. By reducing tax liabilities, these incentives can motivate taxpayers to engage in activities that align with government policy objectives, like economic growth or social welfare. Tax incentives play a crucial role in shaping economic behavior and can significantly impact decisions made by taxpayers.
Tax Incidence: Tax incidence refers to the distribution of the tax burden among individuals or groups in an economy. It illustrates who ultimately bears the cost of a tax, whether it’s consumers, producers, or other parties. Understanding tax incidence is crucial in evaluating the effectiveness and fairness of tax policies, especially in systems that employ progressive rates, as well as assessing how taxes impact overall economic efficiency and simplicity in compliance.
Taxable Income: Taxable income is the portion of an individual's or corporation's income that is subject to taxation by the government. It is calculated by taking gross income and subtracting allowable deductions, leading to the amount on which tax rates are applied. Understanding taxable income is crucial as it directly influences the overall tax liability, and its calculation involves various components such as deductions, accounting methods, and specific forms used for reporting.
Withholding tax: Withholding tax is an amount taken from an employee's paycheck by an employer to cover the employee's income tax liability. This system is designed to collect income tax at the source, ensuring that the government receives tax payments throughout the year rather than waiting until the end of the tax period. Withholding taxes are often based on an employee's income level and filing status, reflecting the principles of a progressive tax system where higher earners face higher rates.
