Adjusted Gross Income (AGI) is a crucial metric in the realm of personal finance and taxation. It represents an individual’s total gross income after deducting specific expenses and adjustments allowed by the Internal Revenue Service (IRS). AGI is used to determine an individual’s taxable income and is a critical factor in establishing the appropriate tax bracket.

Gross Income includes wages, dividends, capital gains, business income, and other sources. Adjustments to income, also known as above-the-line deductions, can include contributions to retirement accounts, student loan interest, and tuition fees.
AGI Components

Importance of AGI
Tax Bracket Determination
AGI is pivotal in determining an individual’s tax bracket and consequently, the rate at which their income is taxed. It influences eligibility for various tax credits and deductions.
Eligibility for Tax Benefits
Several tax benefits and credits are contingent upon an individual’s AGI:
- Earned Income Tax Credit (EITC): A credit for low to moderate-income earners.
- Child Tax Credit: A credit for taxpayers with dependent children.
- Education Credits: Tuition and education-related credits.
Impact on Itemized Deductions
Certain itemized deductions only apply if they exceed a percentage of the AGI:
- Medical Expenses: Deductions available for unreimbursed medical expenses exceeding a specific AGI percentage.
- Casualty and Theft Losses: Only applicable if losses exceed a percentage of the AGI and meet other criteria.
Example Calculation
Suppose an individual has the following components in a tax year:
- Gross income: $95,000
- Adjustments to income: $5,000 (Retirement contributions and student loan interest)
Their AGI would be:
Historical Context
