Understanding AGI and Why It Matters on Your Tax Return

Adjusted Gross Income, or AGI, is one of the most important numbers on your tax return. It's the amount the IRS uses to determine how much federal income tax you owe. Your AGI appears on line 11 of Form 1040 (the main U.S. individual income tax form) and serves as the foundation for many tax calculations.

AGI starts with your total income from all sources. This includes wages from your job, interest from bank accounts, dividends from investments, income from self-employment, rental income, and various other sources. The IRS calls this your "gross income." From this total, you subtract certain deductions that the tax code allows. These deductions are sometimes called "above-the-line" deductions because they reduce your income before you calculate your standard deduction or itemized deductions.

For example, if you earned $50,000 in wages and contributed $3,000 to a traditional Individual Retirement Account (IRA), your AGI would be $47,000. If you had $2,500 in interest income from savings and $500 in student loan interest that you paid, your AGI calculation might look different. The specific number matters because:

• It determines whether you can claim certain tax deductions or credits
• It affects the amount of your standard deduction if you're claimed as a dependent
• It's used to calculate many tax credits, including the Earned Income Tax Credit (EITC) and education credits
• It can affect your Medicare premiums and other government program benefits
• It's the number you report when applying for financial aid for college

Practical Takeaway: Finding your AGI on your tax return tells you the income amount the IRS uses for most tax purposes. Look for it on line 11 of your Form 1040 to locate this crucial number.

Where to Find AGI on Different Tax Forms

Your AGI location depends on which tax form you file. Most individual filers use Form 1040, which is the standard federal income tax return form. On Form 1040, AGI appears on line 11. This is the most common place to find it if you're filing a basic tax return.

If you filed in previous years, you can also find your AGI on past tax returns. The IRS allows you to look up this information using the IRS Free File program or by creating an account on IRS.gov. Your prior year AGI is often requested when you file electronically because it serves as a security measure to confirm your identity.

If you filed Form 1040-SR (for individuals age 65 and older), your AGI also appears on line 11. If you filed a simplified form, such as Form 1040-NR (for nonresident aliens), the location may differ slightly, but the IRS clearly labels AGI on that form as well.

Your W-2 form from your employer is not the same as your tax return, so AGI does not appear there. Your W-2 shows your wages, but does not account for deductions you may have taken. Your 1040 form combines all income sources and subtracts allowable deductions to show your AGI.

When you work with a tax professional or use tax preparation software, these resources calculate your AGI for you. If you prepare your return by hand, you would add all your income sources on the first part of Form 1040, then subtract certain deductions to arrive at AGI.

Practical Takeaway: Check line 11 of your Form 1040 to find your AGI. If you don't have a copy of your return, contact the IRS or log into your online IRS account to view prior-year returns.

Income Sources That Count Toward AGI

AGI includes income from nearly every source you receive money from. Understanding what counts helps you see why your AGI might be higher or lower than you expect.

Wages and salaries are the largest income source for most people. If your employer withheld federal income tax from your paycheck, that money is counted in your gross income and AGI, even though you didn't actually receive it. The amount on your W-2 in Box 1 (Wages, tips, other compensation) is where this income starts.

Interest and dividend income from savings accounts, money market accounts, certificates of deposit (CDs), stocks, and mutual funds all count toward AGI. For example, if your savings account earned $150 in interest during the year, that full $150 is part of your AGI. Many people receive a Form 1099-INT showing interest income or a Form 1099-DIV showing dividend income.

Self-employment income from a business, freelance work, or gig economy jobs counts toward AGI. If you earned $15,000 from freelance writing, that income is part of your AGI. However, you may be able to deduct business expenses from this income before calculating AGI.

Other income sources that count include:

• Rental income from properties you own
• Capital gains from selling stocks, real estate, or other investments
• Taxable Social Security benefits (not all Social Security is taxable, but some may be)
• Unemployment benefits received during the year
• Taxable scholarships or grants
• Income from retirement account distributions (unless you rolled them over)
• Alimony or spousal support received
• Gambling winnings
• Cash tips and gratuities

Practical Takeaway: Review all forms you receive in January and February (W-2s, 1099s, and others) to see all income sources. Add these together to understand what contributes to your AGI.

Deductions That Lower Your AGI

Once you know your total income, certain deductions reduce that amount to get to AGI. These are called "above-the-line" deductions or adjustments to income. They're different from the standard deduction or itemized deductions you may have heard about.

Traditional IRA contributions are one of the most common above-the-line deductions. If you contribute $6,500 to a traditional IRA (the 2024 limit for people under 50), you may deduct that full amount from your gross income. This means your AGI is reduced by the contribution amount. Roth IRA contributions do not reduce AGI.

Self-employment tax is another significant deduction. If you're self-employed, you pay both the employee and employer portions of Social Security and Medicare taxes, which is roughly double what employees pay. You may deduct half of this self-employment tax from your gross income, lowering your AGI.

Student loan interest deductions allow you to reduce AGI by up to $2,500 of interest you paid on student loans during the year. This applies to loans you took out in your own name to pay for education. You must meet income limits to claim this deduction, and there are other rules about which loans qualify.

Educator expenses allow teachers and school staff to deduct up to $300 of classroom supplies and materials they purchased with their own money.

Other above-the-line deductions include:

• Alimony or spousal support paid (if the divorce agreement was finalized before January 1, 2019)
• Tuition and fees for higher education (though this is sometimes subject to income limits)
• Health savings account (HSA) contributions
• Archer medical savings account contributions
• Costs related to moving for work (in very limited circumstances)

Practical Takeaway: Gather receipts and statements for IRA contributions, student loan interest paid, and other deductions mentioned above. These amounts reduce your AGI before other calculations.
