How is gross income different from adjusted gross income and taxable income?

Gross income is the total income earned by an individual before any deductions or taxes, including wages, interest, and dividends. Adjusted Gross Income (AGI) is derived from gross income by subtracting specific deductions, such as retirement contributions and student loan interest. Taxable income is then calculated by taking the AGI and subtracting additional deductions, such as standard or itemized deductions, to determine the income that is subject to taxation. Each step reduces the amount of income that is ultimately taxed.
