📌 What Is Federal Adjusted Gross Income (AGI)?

Adjusted Gross Income (AGI) is your gross income minus specific IRS-allowed deductions, often called “adjustments to income.” Your AGI is the foundation for calculating your taxable income, determining eligibility for tax credits, and even qualifying for certain tax breaks.

Gross income includes:

  • Wages
  • Salaries
  • Dividends
  • Capital gains
  • Business income
  • Retirement distributions

Common adjustments include:

  • Educator expenses
  • Student loan interest
  • Retirement contributions
  • Health savings account (HSA) contributions
  • Self-employment tax deductions

  2. Enter Applicable Adjustments:
    Enter the total amount of deductions or adjustments allowed under IRS rules (e.g., student loan interest, HSA contributions, traditional IRA deductions).
  3. Click “Calculate”:
    Once both inputs are filled, the calculator will compute your Federal AGI automatically.
  4. Review the Result:

🧮 Example: How to Calculate AGI

Let’s take a practical example to understand how it works.

Example 1:

  • Total Gross Income: $75,000
  • Adjustments to Income: $5,000

Calculation:

iniCopyEditAGI = $75,000 – $5,000 = $70,000

In this case, your Adjusted Gross Income would be $70,000, and that’s what will be used to determine your taxable income and potential deductions.

💡 Why Is AGI Important?

Your Adjusted Gross Income plays a crucial role in many aspects of federal taxation:

  • Determines eligibility for deductions such as medical expenses, charitable contributions, and miscellaneous itemized deductions.
  • Impacts education credits like the American Opportunity Credit or Lifetime Learning Credit.
  • Determines eligibility for Roth IRA contributions.
  • Affects health insurance subsidies under the Affordable Care Act.
  • Helps the IRS calculate whether your Social Security benefits are taxable.

📘 Tips for Accurately Estimating AGI

  1. Include All Sources of Income: Don’t forget to add dividends, rental income, and freelance work.
  2. Keep Track of Deductions: These reduce your AGI and can save you significantly on taxes.
  3. Use Last Year’s Tax Return as a Reference: If your finances haven’t changed much, it’s a good starting point.
  4. Double-Check for Overlooked Adjustments: Student loan interest or HSA contributions are often missed.
  5. Be Conservative: When unsure, estimate on the higher end of income and the lower end of deductions to avoid surprises.
