4 Federal Taxation of Individuals Explained

Key Concepts

Gross Income

Gross income includes all income from whatever source derived, such as wages, salaries, interest, dividends, and rental income. It is the starting point for calculating an individual's tax liability. For example, if an individual earns $80,000 in wages and $5,000 in interest, their gross income is $85,000.

Adjusted Gross Income (AGI)

Adjusted Gross Income (AGI) is calculated by subtracting certain allowable deductions from gross income. These deductions include contributions to retirement accounts, alimony payments, and certain business expenses. AGI is a critical figure because it determines eligibility for various tax deductions and credits. For instance, if the individual with $85,000 in gross income contributes $10,000 to a retirement account, their AGI would be $75,000.

Taxable Income

Taxable income is the amount of income subject to tax after accounting for deductions and exemptions. It is calculated by subtracting either the standard deduction or itemized deductions from AGI. For example, if the individual with an AGI of $75,000 takes the standard deduction of $12,950, their taxable income would be $62,050.

Income Tax Rates

Income tax rates are applied to taxable income to determine the tax liability. The U.S. tax system uses a progressive tax rate structure, meaning higher income levels are subject to higher tax rates. For example, for the 2023 tax year, the tax rates range from 10% to 37%, with different rates applying to different portions of taxable income. If the individual with $62,050 in taxable income falls into the 22% tax bracket, their tax liability would be calculated based on the applicable rates for each portion of their income.

Deductions and Credits

Deductions reduce taxable income, while credits reduce tax liability directly. Common deductions include mortgage interest, state and local taxes, and charitable contributions. Common credits include the Child Tax Credit, Earned Income Tax Credit, and Education Credits. For example, if the individual with $62,050 in taxable income qualifies for a $2,000 Child Tax Credit, their tax liability would be reduced by $2,000.

Examples and Analogies

Consider gross income as the "total earnings" before any adjustments. AGI is like the "net earnings" after certain deductions. Taxable income is the "final earnings" subject to tax. Income tax rates are like "graduated fees" applied to different levels of earnings. Deductions and credits are like "discounts" that reduce the final tax bill.

For instance, an individual earning $100,000 in gross income might contribute $15,000 to a retirement account, resulting in an AGI of $85,000. If they take the standard deduction of $12,950, their taxable income would be $72,050. Assuming they fall into the 24% tax bracket and qualify for a $2,500 Education Credit, their tax liability would be calculated based on the applicable rates and reduced by the credit.
