## Method

Form 1040 (2026): AGI = income − adjustments; taxable income = AGI − deduction − Schedule 1-A − QBI; tax by the Tax Table or rate schedule and capital gains rates − child tax credit + other taxes = total tax; refund = payments − (total tax − refundable credits).

## Assumptions

- An estimate for tax year 2026, not tax advice.
- Not modelled: AMT, the premium tax credit, education and other credits, QBI above the Form 8995 threshold, EIC for a separated spouse, the tips, overtime, and car loan deductions, taxable Social Security (type it as other income), 25% and 28% gains, and state tax.
- Everyone 65 or older has an SSN; children under 17 also qualify for the EIC; with no child, someone is 25 to 64.
- Self-employment profit belongs to the wage earner; QBI is profit less half of self-employment tax.

## Worked examples

1. status = single, wages = $60,000.00, interest = $1,000.00, adjustments = $7,000.00 gives totalIncome = $61,000.00, agi = $54,000.00, taxableIncome = $37,900.00. Source: Form 1040 lines 9 to 11: 60,000 + 1,000 − 7,000 (a deductible IRA contribution).
2. status = single, wages = $50,000.00, shortTermGains = -$10,000.00 gives totalIncome = $47,000.00, agi = $47,000.00.
3. status = mfj, wages = $100,000.00, selfEmployment = $20,000.00 gives totalIncome = $120,000.00, selfEmploymentTax = $2,825.91, agi = $118,587.05.

## FAQ

### What is AGI?

Adjusted gross income is your total income for the year minus certain adjustments: half of self-employment tax, deductible IRA and HSA contributions, student loan interest, educator expenses, and a few more (Schedule 1 Part II). It is on Form 1040 line 11.

### How do I calculate my AGI?

Add up all taxable income: wages, interest, dividends, business profit, capital gains (a net loss counts only to −$3,000), unemployment, retirement income, and the taxable part of Social Security. Then subtract your adjustments to income. The result is your AGI.

### What is the difference between AGI and taxable income?

Taxable income is AGI minus the standard or itemized deduction (and a few other deductions such as the QBI deduction and the 2025 to 2028 Schedule 1-A deductions). AGI comes first and is used for many limits; taxable income is what the tax brackets apply to.

### What is the difference between AGI and MAGI?

Modified AGI (MAGI) is AGI with some items added back, such as tax-exempt interest or a deductible IRA contribution. Each rule defines its own MAGI. See the MAGI calculator for the Roth IRA and ACA versions.

### Where do I find last year's AGI?

On last year's Form 1040, line 11. You need it to e-file (to confirm your identity) and for the estimated tax safe harbor.

### What does this calculator leave out?

It takes the adjustments you type as one number; it does not check their own limits (for example the IRA deduction phase-out). The tax it shows leaves out the alternative minimum tax and some credits. It is an estimate, not tax advice.
