The fastest way to find your AGI

Your Adjusted Gross Income (AGI) is on your tax return — either the one you filed or the one the IRS has on record for you. If you filed a return yourself, look at line 11 on Form 1040. If you need the IRS's version of your AGI from a year you already filed, call the IRS at 1-800-829-1040 or use the IRS online account tool at irs.gov.

The IRS online account (sometimes called "Get Transcript") is usually faster than calling. You can see your AGI from the past three years without waiting on hold. You'll need to verify your identity using either a photo ID, a mobile phone number on file with the IRS, or answers to questions about your tax history.

If you need your AGI for a current year that you haven't filed yet, you cannot get it from the IRS — only you know what it will be. You'll need to calculate it yourself using your income documents and deductions, or work with a tax preparer.

Key Takeaways

  • Your AGI appears on line 11 of Form 1040 if you have a copy of your filed return.
  • The IRS online transcript tool at irs.gov lets you view your AGI from prior years without calling.
  • To use the online tool, you must verify your identity using a photo ID, phone number, or tax history questions.
  • If you need your AGI for a year you haven't filed yet, you must calculate it yourself from your income and deduction records.

Using the IRS Get Transcript tool online

The IRS's "Get Transcript" tool is the fastest option if you want to see your AGI from a prior year. Go to irs.gov, search for "Get Transcript," and select the online option. You'll be asked to verify your identity before you can see anything.

Identity verification happens in real time. The IRS will ask you to use either a photo ID (driver's license or passport), a phone number registered with the IRS, or answers to security questions based on your credit history. Once verified, you can view transcripts for the past three years immediately and download them as a PDF.

The transcript you receive will show your AGI clearly. You can also request transcripts by mail if you prefer, though this takes 5 to 10 business days.

Calling the IRS directly

If you cannot use the online tool or prefer to speak with someone, call the IRS at 1-800-829-1040. Have your Social Security number, date of birth, and filing status ready. The IRS will verify your identity over the phone before giving you your AGI.

Wait times vary by season. During tax season (January through April), hold times can be 30 minutes or longer. Outside tax season, you may reach someone more quickly. The IRS also offers a callback option on some calls — you can request a call back instead of waiting on hold.

Finding AGI on documents you already have

If you have a copy of your filed tax return, your AGI is on line 11 of Form 1040. This is the same number the IRS has on record, so you don't need to contact them.

You may also find your AGI on other documents. If you received a mortgage, student loan, or financial aid, the lender or school may have asked for your AGI and kept a record. Your tax preparer or accountant will also have this information if you paid someone to file your return.

What to do if you haven't filed yet

If you're trying to find your AGI for a tax year you haven't filed yet, the IRS cannot provide it — they only know what you report to them. You'll need to calculate it yourself.

Start with your total income from all sources (wages, self-employment, interest, dividends, and other income). Then subtract specific deductions like educator expenses, student loan interest, or contributions to a traditional IRA. The result is your AGI. If you're unsure how to calculate it, a tax preparer can walk you through it, or you can use IRS Publication 17, which explains AGI step by step.

Why you might need your AGI

AGI is used to determine whether you meet income limits for tax deductions, credits, and other programs. Schools use it for financial aid decisions. Some government assistance programs also ask for your AGI to check whether you meet their income thresholds.

When someone asks for your AGI, they usually want the number from a specific tax year. Make sure you know which year they're asking about — your AGI changes from year to year.

Frequently Asked Questions

Can I get someone else's AGI from the IRS?

No. The IRS will only release tax information to the person whose name is on the return, their spouse (if filing jointly), or someone with a power of attorney. If you need a dependent's AGI, the dependent must request it themselves or give you written permission.

What if I filed my return but the IRS shows a different AGI?

The IRS may have corrected errors on your return or received additional income information (like a 1099 form) after you filed. Contact the IRS at 1-800-829-1040 to find out what changed. If you disagree with the change, you can file an amended return on Form 1040-X.

How far back can I get my AGI from the IRS?

The IRS online transcript tool shows the past three years. If you need AGI from earlier than that, call 1-800-829-1040 or request a transcript by mail. The IRS keeps records going back much further, though retrieval may take longer.

Do I need my AGI to file my taxes?

No. Your AGI is calculated as part of filing your return — you don't need to know it beforehand. You only need your AGI after you've filed, usually when applying for loans, aid, or benefits that have income limits.
