Total Income
Form 1040, line 9. Enter every taxable source. Leave a field at 0 if it does not apply.
A net capital loss deduction is generally limited to $3,000 per year ($1,500 if married filing separately).
Adjustments to Income
Schedule 1, Part II (line 26). These above-the-line adjustments come off your total income to produce AGI.
Educator expenses are capped at $300 per educator for 2026 ($600 if married filing jointly and both spouses are educators). Clamped to $300.
Student loan interest is capped at $2,500 per return (IRC section 221). Clamped to $2,500.
Your adjustments exceed your total income, so AGI is negative. The taxable income preview is held at $0.

What Is Adjusted Gross Income (AGI)?
Adjusted gross income is your total income from all sources minus a short list of above-the-line adjustments. It's the number on Form 1040, line 11, and it sits between your total income (line 9) and your taxable income (line 15). Put plainly, AGI is what you earned before your standard or itemized deduction comes off.
AGI matters because it's the gateway figure for the rest of your return. The IRS uses it, often after a small modification into MAGI, to decide whether you qualify for credits and deductions and where they start to phase out. Your AGI also feeds straight into your taxable income, the number the tax brackets actually apply to.
How to Calculate Your AGI Step by Step
The path runs through three lines on Form 1040:
- Total income (line 9): add wages, taxable interest, dividends, capital gains, self-employment profit, taxable retirement distributions, unemployment, and any other taxable income.
- Adjustments to income (Schedule 1, line 26, carried to line 10): total your above-the-line adjustments.
- AGI (line 11): subtract line 10 from line 9.
Here are the 2026 above-the-line adjustments and their caps:
| Adjustment | 2026 cap or note |
|---|---|
| Educator expenses | $300 per educator ($600 MFJ if both qualify) |
| HSA deduction | Limited by the annual HSA contribution limit on Form 8889 |
| Deductible part of self-employment tax | One-half of your self-employment tax |
| SEP / SIMPLE / qualified plan | Limited by plan contribution rules |
| Self-employed health insurance | Cannot exceed your net self-employment earnings |
| Early-withdrawal penalty | From your 1099-INT or 1099-OID |
| Traditional IRA deduction | Limited by the annual IRA contribution limit and coverage rules |
| Student loan interest | $2,500 hard cap (IRC section 221), phases out at higher income |
If you're self-employed, the deductible half of your self-employment tax is its own adjustment. The Self-Employment Tax Calculator works out that figure. The Traditional IRA Deduction Calculator and Student Loan Interest Deduction Calculator handle the two capped adjustments that trip people up most.
AGI vs. MAGI vs. Taxable Income
These three figures stack in order, and mixing them up gives you the wrong eligibility answer:
| Figure | How it is built | What it is used for |
|---|---|---|
| AGI (line 11) | Total income minus adjustments | The base figure for the whole return |
| MAGI | AGI plus benefit-specific add-backs | Roth IRA, IRA deduction, ACA credit, IRMAA, NIIT eligibility |
| Taxable income (line 15) | AGI minus standard or itemized deduction (and QBI) | The amount the tax brackets apply to |
There isn't one single MAGI: the add-backs differ by purpose, so the MAGI for a Roth IRA isn't the same as the MAGI for Medicare IRMAA. To run the correct formula for a specific benefit, use the MAGI Calculator. To see how taxable income breaks across the 2026 brackets, use the Tax Bracket Calculator.
Why Your AGI Matters for 2026 Taxes
A long list of credits and deductions phase out as AGI (or its MAGI cousin) rises, including the child tax credit, education credits, the saver's credit, and the IRA deduction. A modest change in AGI can push you across a phase-out line and change what you owe, so it's worth getting the number right before you plan around it.
The 2026 figures here reflect the One Big Beautiful Bill Act (P.L. 119-21), which set the standard deduction amounts and bracket thresholds used in the taxable income preview.

Frequently Asked Questions
Common questions about agi calculator
What is adjusted gross income (AGI)?
AGI is your total income from all sources minus a set of above-the-line adjustments known as adjustments to income. You'll find it on Form 1040, line 11, sitting between your total income and your taxable income. It's the starting point the IRS uses to test eligibility for many credits and deductions.
How do I calculate my AGI for 2026?
Add up every source of income: W-2 wages, taxable interest, dividends, capital gains, self-employment profit, retirement distributions, unemployment, and other taxable income. That total goes on Form 1040, line 9. Then subtract your Schedule 1 adjustments (line 10), like the deductible half of self-employment tax, HSA and IRA contributions, and student loan interest. What's left is your AGI on line 11.
Where do I find my AGI on my tax return?
AGI appears on Form 1040, line 11. If you're pulling a prior-year figure for identity verification or e-filing, it's the same line 11 number from that year's return.
What is the difference between AGI and MAGI?
MAGI is your AGI with certain deductions and exclusions added back in. There isn't one single MAGI: the add-backs change depending on the benefit, whether that's Roth IRA contributions, the ACA premium tax credit, Medicare IRMAA, or the net investment income tax. For most filers with no exclusions, MAGI equals AGI. To run the right formula for a specific benefit, use the MAGI Calculator at /tools/magi-calculator/.
What is the difference between AGI and taxable income?
Taxable income is AGI minus your standard or itemized deduction (and the qualified business income deduction if it applies), so it's a later and usually lower figure. AGI comes first on line 11; taxable income lands on line 15. The brackets that set your tax apply to taxable income, which you can check with the Tax Bracket Calculator at /tools/tax-bracket-calculator/.
What counts as an above-the-line deduction (adjustment to income)?
Common adjustments to income include educator expenses, the HSA deduction, the deductible half of self-employment tax, SEP and SIMPLE plan contributions, self-employed health insurance, the early-withdrawal penalty on savings, the traditional IRA deduction, and student loan interest. These come off your total income on Schedule 1 to produce AGI, and you can claim them whether or not you itemize.
Is the student loan interest deduction really capped at $2,500?
Yes. Under IRC section 221, the student loan interest deduction is capped at $2,500 per return per year, and it phases out at higher income levels. This calculator clamps the entry at $2,500. For the income phase-out detail, see the Student Loan Interest Deduction Calculator at /tools/student-loan-interest-deduction-calculator/.
Does AGI include the standard deduction?
No. AGI is calculated before the standard or itemized deduction is applied. The standard deduction is subtracted from AGI to get to taxable income, so AGI is always the higher of the two figures.
