Components of Gross Income: A Detailed Look
Category | Individuals | Businesses |
---|---|---|
Employment Income | Salaries, wages, bonuses, commissions, tips | Not applicable (this is income for individuals employed by the business) |
Self-Employment Income | Income from freelance work, consulting, sole proprietorships | Revenue from services provided, goods sold, or other business activities |
Investment Income | Interest from savings accounts, dividends from stocks, capital gains from selling assets | Interest on business deposits, dividends from company stock holdings, capital gains from the sale of business assets |

Other Income | Alimony received, gambling winnings, lottery winnings, jury duty pay, prizes and awards | Income from lawsuits, government subsidies, insurance claims, non-operating income |
Understanding Capital Gains
Capital gains are the profits you make from selling an asset like stocks, bonds, or real estate. These are generally included in your gross income, but the tax rate can vary depending on how long you held the asset.
Gross Income vs. Net Income
- Gross Income: Total income before any deductions.
- Net Income: “Take-home” income after taxes and other deductions.

Adjusted Gross Income (AGI) and Modified Adjusted Gross Income (MAGI)
- AGI: Calculated by subtracting certain above-the-line deductions from your gross income (e.g., contributions to traditional IRAs, student loan interest). AGI is used to determine eligibility for various tax benefits and credits.
- MAGI: A further refinement of AGI used to determine eligibility for specific tax benefits (e.g., Roth IRA contributions, Premium Tax Credit).
Recordkeeping Best Practices
