ADJUSTED GROSS INCOME (AGI)
Back to GlossaryDefinition
Annual gross income minus certain adjustments that the IRS uses to determine a persons or companies income tax liability for the year.
Summary
Adjusted Gross Income (AGI) is your total income for the year after subtracting specific deductions allowed by the IRS, but before taking the standard deduction or itemized deductions. Think of it as a crucial 'checkpoint' number that determines your eligibility for many tax benefits, credits, and deductions. It's found on line 11 of Form 1040 and serves as the foundation for calculating your final tax liability.
Usage Context
Understanding AGI is essential when learning about tax calculations, determining eligibility for tax credits like the Earned Income Credit, calculating phase-outs for deductions, and understanding how different types of deductions work in the tax system.
Common Confusions
- Confusing AGI with gross income or taxable income
- Not understanding that AGI is calculated before standard/itemized deductions
- Thinking all deductions reduce AGI (only above-the-line deductions do)
- Assuming AGI is the final number used to calculate taxes
- Not realizing AGI determines eligibility for many tax benefits
