What is AGI (Adjusted Gross Income)?

Adjusted Gross Income (AGI) is one of the most important numbers on your federal tax return. It starts with your total taxable income and then subtracts specific IRS-approved adjustments, often called above-the-line deductions. AGI is used to determine eligibility for many tax credits, deductions, and phaseouts.

How AGI is calculated

The basic AGI formula is straightforward:

AGI = Total Income - Adjustments to Income

Total income can include wages, business income, capital gains, taxable retirement distributions, unemployment compensation, and other taxable income sources. Then you subtract qualifying adjustments such as HSA contributions, deductible IRA contributions, or student loan interest.

Common AGI adjustments people forget

1) HSA deductions

If you made eligible Health Savings Account contributions outside payroll, those can reduce AGI. Many taxpayers overlook this when estimating taxes manually.

2) Self-employed deductions

Self-employed filers may qualify for deductions like self-employed health insurance and certain retirement plan contributions. These can significantly change AGI.

3) Student loan interest

Even a modest deduction here can matter, especially when your AGI is near phaseout ranges for credits and other tax benefits.

AGI vs. Taxable Income vs. MAGI

AGI: Total income minus qualifying adjustments.
Taxable Income: AGI minus either the standard deduction or itemized deductions (and other qualified deductions, if applicable).
MAGI: Modified AGI used for specific rules (for example, IRA contribution eligibility or premium tax credits). Different tax provisions can define MAGI differently.

Quick example

Suppose your wages are $80,000, interest/dividends are $1,000 total, and side business income is $4,000. Your total income is $85,000. If you have $2,000 in student loan interest and $3,000 in deductible retirement contributions, total adjustments are $5,000.

Estimated AGI = $85,000 - $5,000 = $80,000

Why AGI matters so much

A lower AGI can improve eligibility for credits, lower phaseout impacts, and reduce your overall federal tax burden. Even small adjustments can make a meaningful difference.
