Gross income means different things depending on whether you are looking at an individual’s U.S. federal tax return or a business’s books. For federal income tax, it generally includes income from all sources unless a law excludes it. In a common sole-proprietor calculation, gross receipts are reduced by returns and allowances, then by cost of goods sold, to arrive at gross profit. These figures are related, but they are not interchangeable.
What does gross income mean?
For U.S. federal income tax, Internal Revenue Code § 61(a) says: “Except as otherwise provided in this subtitle, gross income means all income from whatever source derived, including (but not limited to) the following items.” The statute names compensation for services, business income, gains from property dealings, interest, rents, royalties, dividends, and pensions, among other categories. The definition is broad, but statutory exclusions and special rules can change how a particular item is treated. Read Internal Revenue Code § 61.
For individuals, gross income is not limited to a paycheck or base salary. IRS guidance on personal-service income includes wages, salaries, commissions, fees, tips, fringe benefits, and stock options, subject to applicable exclusions and special rules. IRS Publication 525: Taxable and Nontaxable Income.
Is gross income before or after taxes?
In everyday discussions of pay, gross income usually means earnings before payroll and income-tax withholding. On an individual federal tax return, however, “gross income” is a tax-law measure, not simply a synonym for salary before withholding. It can include income beyond employment pay, and some amounts may be excluded under specific rules.

Gross income is also not necessarily the final amount on which a taxpayer pays tax. Adjusted gross income (AGI) is calculated later after specified adjustments; taxable income is determined later still after applicable deductions. The exact calculation depends on the taxpayer’s circumstances and current tax rules.
How do I calculate gross income for a business?
For a sole proprietor reporting business activity on Schedule C, the IRS shows a sequence from gross receipts to gross profit. Gross receipts are the business’s starting sales or receipts figure; returns and allowances reduce that amount to net receipts. Cost of goods sold is then subtracted to determine gross profit. IRS Publication 334 (2025), Tax Guide for Small Business.

| Schedule C calculation step | IRS 2025 retail illustration |
|---|---|
| Gross receipts | $400,000 |
| Less: returns and allowances | $14,940 |
| Net receipts | $385,060 |
| Less: cost of goods sold | $288,140 |
| Gross profit | $96,920 |
These figures are the IRS’s worked retail-business illustration in its 2025 edition of Publication 334; they are not an average or typical business result. If merchandise sales are not an income-producing factor, the IRS says a business generally does not need to figure cost of goods sold for this calculation, and gross profit is the same as net receipts.
Gross income, gross revenue, gross profit, and net income: what is the difference?
The terms depend on the document and context. In the Schedule C sequence above, gross receipts are reduced by returns and allowances to get net receipts, and cost of goods sold is subtracted to get gross profit. Gross profit is still before other operating expenses such as rent, marketing, or administrative costs.
- Gross receipts or gross revenue: A before-cost starting figure, but the precise items included depend on the tax form, accounting statement, or legal document.
- Gross profit: In the cited Schedule C calculation, net receipts minus cost of goods sold.
- Net income or net profit: A later result after additional expenses and relevant tax or accounting treatments. Its exact meaning depends on the document.
- Adjusted gross income (AGI): An individual tax-return calculation after specified adjustments to gross income.
- Taxable income: A later tax calculation after applicable deductions; it is not automatically equal to gross income.
Business terminology can also vary across legal forms. A U.S. Courts bankruptcy glossary, for example, defines a company’s “gross income” as gross revenue minus cost of goods sold, and “gross revenue” as operating amounts before expense deductions. That is a definition used in that glossary’s bankruptcy context, not a universal accounting rule. U.S. Courts bankruptcy glossary.
Does gross income include business expenses?
Gross income or gross receipts are generally figures before many business expenses are deducted. In the Schedule C sequence, cost of goods sold is subtracted to calculate gross profit; other operating costs, such as rent and marketing, are not part of that gross-profit step. Later calculations may account for other deductible expenses according to the applicable tax rules. Keep receipts, sales, returns, inventory and expense records clear enough to identify which calculation each amount belongs to.

When does a business count income: when earned or when received?
Timing depends on the accounting method and applicable rules. Under the cash method, a sole proprietor generally includes amounts actually or constructively received during the tax year. Under the accrual method, income and expenses are generally reported when earned or incurred, subject to tax rules; inventory can also affect the calculation. See IRS Publication 334 (2025) for small-business accounting-method and inventory guidance. Do not assume that all income is counted only when money physically arrives in a bank account.

Use records that make the path from receipts to later profit figures auditable: sales records, documentation of returns and allowances, inventory and cost-of-goods-sold records where applicable, and expense documentation. The IRS identifies formal books and records, accounting or financial software, and a separate business bank account as useful ways to help track and report business income. IRS Fact Sheet FS-2006-25.
