Adjusted Gross Income (AGI) is a crucial figure on tax returns that reflects an individual’s total income after accounting for specific deductions, but before personal exemptions and itemized deductions. AGI serves as the basis for determining taxable income and eligibility for various tax credits and deductions. It is an essential calculation for tax purposes in several countries, notably the United States.
Definition and Formula
\(\text{AGI} = \text{Gross Income} - \text{Adjustments}\)
AGI is gross income minus certain deductions, known as adjustments to income. Gross income includes all income sources, such as wages, interest, dividends, rental income, and business profits.
Key Adjustments to Income
To calculate AGI, taxpayers can subtract several adjustments from their gross income. Common examples include:
- Educator expenses
- Student loan interest deduction
- Tuition and fees deduction
- IRA contributions
- Health savings account (HSA) contributions
- Self-employment tax
- Alimony payments (for agreements prior to tax changes in 2019)
- Moving expenses (for certain armed forces members)
These adjustments can vary slightly depending on tax laws prevailing in the filing year.
Significance of AGI
Taxable Income Calculation
AGI is a pivotal figure when determining taxable income. After calculating AGI, taxpayers apply either the standard deduction or itemized deductions to ascertain their taxable income, which directly impacts the tax payable.
Eligibility for Credits and Deductions
Eligibility for various tax credits and deductions often depends on AGI. For example, tax credits such as the Child Tax Credit and deductions like the Medical Expense Deduction use AGI as a threshold.
Historical Context
AGI became a standardized metric in the United States system with the establishment of the modern federal income tax system in the early 20th century. Its role has evolved alongside tax legislation, adapting to changes in the economic landscape and tax policy reforms.
