Introduction
Adjusted Gross Income (AGI) represents a crucial figure in the U.S. tax system, signifying the difference between a taxpayer’s gross income and specific adjustments allowed by the IRS. Understanding AGI is essential for determining a taxpayer’s federal taxable income and eligibility for various deductions and credits.
Historical Context
The concept of AGI emerged with the Internal Revenue Code (IRC) of 1954 and was further refined by subsequent amendments and tax reforms, including the Tax Reform Act of 1986 and the Tax Cuts and Jobs Act of 2017.
Types and Categories
- Gross Income: Total income received in a year, including wages, dividends, capital gains, business income, and more.
- Adjustments to Income: Specific deductions allowed by the IRS, such as educator expenses, student loan interest, alimony payments, and contributions to retirement accounts.
Key Events

-
Married Filing Jointly:

Interesting Facts
