AGI

Understanding Adjusted Gross Income (AGI)

Adjusted Gross Income (AGI) is a key financial metric used by the Internal Revenue Service (IRS) to determine your annual taxable income. AGI represents your total gross income minus specific tax adjustments, often referred to as "above-the-line" deductions.

Knowing your AGI is critical because it is the baseline from which your final tax liability is calculated. Your AGI determines which tax brackets you fall into and your eligibility for various deductions, tax credits, and savings plans. Once you know your AGI, you can estimate your total federal taxes using our Income Tax Calculator.

What is Included in Gross Income?

Gross income includes all earnings you receive throughout the year that are subject to tax. These include:

• Wages, salaries, and tips: Your primary earnings from employment.
• Taxable interest and dividends: Earnings from bank accounts, investments, and stock holdings.
• Capital gains: Profits made from selling assets like stocks or property.
• Business income: Net profits earned from sole proprietorships or freelance work.
• Pensions and retirement distributions: Taxable payouts from traditional IRAs or 401(k) plans.

What are Above-the-Line Deductions?

Above-the-line deductions are adjustments that reduce your gross income directly, even if you do not itemize your deductions on your tax return. Common adjustments include:

• Student loan interest: Deductions for interest paid on qualified student loans.
• Educator expenses: Out-of-pocket classroom expenses for eligible teachers.
• HSA contributions: Pre-tax contributions made to a Health Savings Account.
• Traditional IRA contributions: Contributions made to a qualified retirement account.
• Self-employed expenses: Deductions for health insurance premiums, SEP-IRA contributions, and half of self-employment taxes.

How to Calculate AGI

The formula for AGI is straightforward:

\[\text{AGI} = \text{Total Gross Income} - \text{Total Above-the-Line Deductions}\]
