Your AGI is on line 11 of Form 1040, or line 15 of Form 1040-SR if you're 65 or older

Adjusted Gross Income (AGI) is the number the IRS uses to determine how much tax you owe and whether you can claim certain deductions and credits. It starts with your total income from all sources, then subtracts specific deductions like student loan interest, IRA contributions, or self-employment tax. The result is your AGI, and it appears in the same place on every federal tax return.

If you filed Form 1040 (the standard individual income tax form), look at line 11. If you filed Form 1040-SR (the version for people 65 and older), your AGI is on line 15. Both forms are laid out so that AGI is clearly marked and straightforward to spot once you know where to look.

Your AGI also appears on your state tax return, though the line number varies by state. Many states use AGI from your federal return as a starting point, then make their own adjustments. If you need your state AGI, check your state tax form or your state's tax department website.

Key Takeaways

  • AGI appears on line 11 of Form 1040 and line 15 of Form 1040-SR for federal tax returns.
  • AGI is calculated by taking your total income and subtracting above-the-line deductions like student loan interest, educator expenses, and self-employment tax.
  • You need your AGI to claim many tax credits, determine deduction limits, and file certain other forms.
  • If you use tax software or a tax professional, the software or professional will calculate and display your AGI automatically.
  • State tax returns may use your federal AGI as a starting point but may have different line numbers or additional adjustments.

How AGI is calculated from your income

AGI starts with your total income, which includes wages from a W-2 job, self-employment income, interest, dividends, capital gains, rental income, and any other money you received. This total is sometimes called "gross income."

From that total, you subtract above-the-line deductions. These are deductions you can claim whether or not you itemize. Common ones include:

  • Student loan interest (up to $2,500 per year)
  • IRA contributions (traditional IRA only; Roth contributions don't reduce AGI)
  • Self-employment tax (half of what you paid)
  • Health savings account (HSA) contributions
  • Educator expenses (up to $300 per year for teachers)
  • Tuition and fees deduction (if you meet income limits)

The result after subtracting these deductions is your AGI. It is not the same as your taxable income—that comes later, after you subtract either the standard deduction or itemized deductions. But AGI is the number that determines whether you can claim many credits and deductions in the first place.

Why you need to know your AGI

The IRS uses AGI to set income limits for dozens of tax breaks. If your AGI is too high, you cannot claim the child tax credit, the earned income tax credit, education credits, or the saver's credit. Many deductions—like the deduction for medical expenses or charitable contributions—are also limited based on AGI.

You also need your AGI to file certain forms. If you claim the child and dependent care credit, you report your AGI on Form 2441. If you claim education credits, you report it on Form 8863. If you have self-employment income, your AGI appears on Schedule C and then flows to Form 1040.

Outside of taxes, you may need your AGI for financial aid forms, mortgage applications, or to prove income for other purposes. Many of these forms ask specifically for your AGI rather than gross income or taxable income, so knowing where to find it matters.

Finding AGI on a printed or PDF tax return

If you have a paper copy of your return or a PDF, open Form 1040 or Form 1040-SR and look at the right side of the form. The lines are numbered down the left margin. Scan down until you see line 11 (Form 1040) or line 15 (Form 1040-SR). The number printed next to that line is your AGI.

The form is organized so that income lines come first, then deductions, then AGI. You will see your wages on line 1, interest on line 2, dividends on line 3, and so on. Below those, you will see a section for deductions. Line 11 or 15 comes right after the deduction section and is clearly labeled "Adjusted Gross Income."

If you cannot locate it, check the IRS website for a blank Form 1040 or Form 1040-SR. The IRS provides a filled-in example showing where each line goes, which can help you orient yourself on your own return.

Finding AGI if you used tax software

If you prepared your return using tax software like TurboTax, H&R Block, or TaxAct, the software calculates your AGI automatically and displays it on screen. Usually it appears at the end of the income and deduction section, before you move on to credits and other items. The software will also show it on the Form 1040 preview before you file.

You can also find your AGI in the tax return summary or on the final return document the software generates. Most software lets you print or save a PDF of your complete return, which will show line 11 or 15 with your AGI filled in. If you need to reference it later, save that PDF or take a screenshot.

If you filed electronically and no longer have the software open, you can retrieve your return through the IRS website using your login credentials, or you can request a transcript from the IRS that includes your AGI.

Getting your AGI from the IRS if you don't have your return

If you filed a return but cannot find it, the IRS can provide your AGI. The fastest way is to use the IRS transcript tool on the IRS website (irs.gov). You can create a login, request a transcript, and view your AGI online within minutes. The IRS offers several types of transcripts; the "Account Transcript" includes your AGI and is free.

You can also call the IRS at 1-800-829-1040 and speak to a representative, though wait times are often long. Have your Social Security number, filing status, and the tax year ready. The IRS can read your AGI to you over the phone or mail a transcript to your address on file.

If you filed jointly with a spouse, both spouses' names and Social Security numbers may be needed to retrieve the transcript. If you filed a return for a year you no longer remember, the IRS can tell you which years you have on file.

State tax returns and AGI

Most states use your federal AGI as the starting point for calculating state income tax. However, some states make adjustments—adding back certain deductions or subtracting state-specific items—so your state AGI may differ from your federal AGI.

On your state return, AGI may appear on a different line number than on your federal return. Check your state's tax form or your state's tax department website to find the exact line. Some states label it "Federal AGI" if they are using the federal number directly, while others calculate their own version and label it "State AGI" or "Adjusted Gross Income."

If you need your state AGI for a specific purpose, your state tax return or a transcript from your state tax authority will show it. Many states offer online transcript tools similar to the IRS, or you can contact your state tax department by phone.

Frequently Asked Questions

Is AGI the same as my taxable income?

No. AGI is calculated first, then you subtract either the standard deduction or itemized deductions to arrive at taxable income. Taxable income is what you actually owe tax on. AGI is used to determine whether you can claim certain deductions and credits in the first place.

Can my AGI be negative?

Yes, if your deductions exceed your income. This usually happens if you have a large business loss or capital loss. A negative AGI means you owe no federal income tax and may be able to carry the loss forward to future years. Consult a tax professional about how to handle losses on your return.

Do I need to report my AGI when I file?

No. You report your income and deductions, and the IRS or your tax software calculates AGI automatically. You do not fill in line 11 or 15 yourself; it is the result of the lines above it. However, you do need to know your AGI for other purposes, like filling out financial aid forms or mortgage applications.

What if the line numbers changed from last year?

The IRS occasionally updates Form 1040 and adds or removes lines. If you are comparing returns from different years, check the year on the form itself. The most recent Form 1040 has AGI on line 11; Form 1040-SR has it on line 15. If you filed several years ago, the line number may have been different, but your tax software or a transcript will show you the correct figure.

Can I use my W-2 as my AGI?

No. Your W-2 shows only your wages from that employer. AGI includes all your income from all sources, minus deductions. If you have only one W-2 and no other income or deductions, your AGI will be close to your W-2 wages, but it is not the same number.
