Frequently Asked Questions
What is Adjusted Gross Income (AGI)?
Adjusted Gross Income (AGI) is your total gross income minus specific deductions called above-the-line adjustments. These include contributions to traditional IRAs, student loan interest paid, health savings account contributions, and alimony payments. AGI is the starting point for calculating your taxable income and determines eligibility for many tax credits and deductions.
Where do I find my AGI on my tax return?
Your AGI appears on line 11 of IRS Form 1040 for tax year 2024. It is calculated by subtracting above-the-line deductions from your total gross income (wages, salaries, tips, interest, dividends, business income, and other income sources reported on your tax return).
What is the difference between AGI and MAGI?
MAGI (Modified Adjusted Gross Income) starts with your AGI and adds back certain deductions like foreign earned income exclusion, tax-free interest, and non-taxable Social Security benefits. MAGI is used to determine eligibility for Roth IRA contributions, premium tax credits, and the child tax credit. Use our MAGI Calculator to compute your MAGI.
What deductions reduce my AGI?
Above-the-line deductions that reduce your AGI include: Traditional IRA contributions, HSA contributions, student loan interest (up to $2,500), educator expenses ($300), self-employment tax (half), self-employed health insurance premiums, alimony paid (pre-2019 divorces), and moving expenses for military members.
Why is my AGI important?
Your AGI determines eligibility for many tax benefits including: IRA contribution phaseouts, Roth IRA eligibility, premium tax credit eligibility, child tax credit phaseouts, the American Opportunity Tax Credit, and the Lifetime Learning Credit. It also determines whether you can deduct medical expenses and charitable contributions.
Can my AGI be negative?
Yes, in certain circumstances, AGI can be negative. This may occur if the deductions claimed exceed the total income, resulting in a negative AGI. However, a negative AGI does not necessarily mean a refund or negative tax liability. The tax owed is determined by the taxable income, not the AGI.
What is the difference between AGI and taxable income?
AGI is your gross income minus above-the-line deductions. Taxable income is your AGI minus either the standard deduction or itemized deductions (below-the-line deductions). For 2024, the standard deduction is $14,600 for single filers, $29,200 for married filing jointly, and $21,900 for head of household.
How does AGI affect eligibility for tax credits?
Your AGI determines eligibility for income-limited tax credits such as the Earned Income Tax Credit (EITC), Child Tax Credit (CTC), Premium Tax Credit (PTC), American Opportunity Tax Credit (AOTC), and the Lifetime Learning Credit (LLC). Most credits phase out gradually as AGI exceeds certain thresholds based on filing status.
