1. Historical Background of Federal Income Taxation
The history of federal income taxation in the United States provides context for understanding its current framework.
1.1. Origins of Federal Income Tax
- The first federal income tax was introduced during the Civil War in 1861 to help pay war expenses.
- The Revenue Act of 1861 imposed a tax on personal incomes, but it was repealed after the war.
- In 1894, another income tax was enacted, but it was declared unconstitutional by the Supreme Court in 1895.
1.2. 16th Amendment
- The 16th Amendment, ratified in 1913, granted Congress the authority to levy a federal income tax without apportioning it among the states.
- This amendment established a legal foundation for the modern income tax system.
1.3. Development Over the Years
- The federal income tax has evolved significantly since the 1913 tax rates, which started at 1% and reached a maximum of 7%.
- The introduction of graduated tax rates and various credits and deductions over the years has shaped the current tax structure.
2. Basic Structure of Federal Income Taxation
Understanding the structure of federal income taxation is essential for taxpayers and tax professionals.
2.1. Who is Subject to Federal Income Tax?
- U.S. citizens and residents are subject to federal income tax on their worldwide income.
- Non-resident aliens are taxed only on their U.S.-source income.
2.2. Types of Income Subject to Tax
- Ordinary income: Wages, salaries, bonuses, and self-employment income.
- Investment income: Interest, dividends, and capital gains.
- Other income: Rental income, royalties, and alimony.
2.3. Tax Rates and Brackets
- The federal income tax system operates on a progressive basis, meaning tax rates increase with taxable income.
- Tax brackets for individuals are adjusted annually for inflation.
3. Determining Taxable Income
Taxable income is the foundation for calculating federal income tax liability.
3.1. Gross Income
- Gross income includes all income received in the form of money, goods, or services that is not specifically exempt from tax.
- Examples of gross income include wages, dividends, and capital gains.
3.2. Adjusted Gross Income (AGI)
- AGI is calculated by subtracting certain adjustments from gross income (e.g., contributions to retirement accounts, student loan interest).
- AGI is a crucial figure used to determine eligibility for various tax credits and deductions.
3.3. Deductions and Exemptions
- Standard Deduction: A flat amount that reduces taxable income based on filing status (single, married filing jointly, etc.).
- Itemized Deductions: Specific expenses that taxpayers can deduct from their gross income, such as mortgage interest, state and local taxes, and charitable contributions.
- Personal Exemptions: Previously allowed deductions for each taxpayer and dependent, though suspended from 2018 to 2025 under the Tax Cuts and Jobs Act.
4. Tax Credits and Liabilities
Tax credits directly reduce the amount of tax owed, while liabilities represent the total tax obligation.
4.1. Types of Tax Credits
- Nonrefundable Credits: Only reduce tax liability to zero but do not result in a refund (e.g., Child Tax Credit).
- Refundable Credits: Can result in a refund if they exceed the taxpayer’s liability (e.g., Earned Income Tax Credit).
4.2. Tax Liability Calculation
- The basic formula for calculating tax liability is:
- Taxable Income x Applicable Tax Rate = Tax Liability
- Tax liabilities can also include additional taxes, such as self-employment taxes or alternative minimum tax (AMT).
