An income statement contains five groups of accounts: revenue, cost of goods sold, operating expenses, non-operating items, and income taxes. Each group feeds a subtotal, and the subtotals stack from the top line down to net income. The specific accounts a company reports depend on its industry and complexity, but under Generally Accepted Accounting Principles the structure holds across businesses. The accounts found on an income statement are the same whether the statement is laid out in a single-step or multi-step format; only the grouping and subtotals differ.
Revenue Accounts
Revenue sits at the top and captures the economic benefit a company earns from its core operations. A retailer or manufacturer usually labels this line gross sales or net sales. A professional services firm reports service revenue or fee income. Whatever the label, this account represents the total value of goods delivered or services performed during the period.
Gross revenue rarely reaches the bottom line intact. Several contra-revenue accounts pull it down to a net figure:
- Sales returns, which reflect merchandise customers sent back.
- Sales allowances, which cover price reductions granted after delivery, often for minor defects or shipping damage.
- Sales discounts, which record early-payment incentives offered to buyers.
Subtracting these accounts from gross revenue produces net revenue, the starting point for measuring profitability.
Cost of Goods Sold Accounts
Directly below revenue, the cost of goods sold (COGS) section captures every expense tied to producing or purchasing the items a company sells. Net revenue minus COGS gives you gross profit, the most basic measure of whether products are priced above their production cost.
The main accounts here are:
- Raw materials, meaning the purchase price of physical components that go into a finished product.
- Direct labor, meaning wages paid to workers who manufacture, assemble, or process goods.
- Manufacturing overhead, which covers factory-related costs like equipment maintenance, utilities for production facilities, and supplies used on the shop floor.
For retailers that buy finished goods rather than manufacture them, COGS is simpler. It is essentially the wholesale cost of inventory sold during the period.
Inventory valuation changes these totals. Under FIFO (first-in, first-out), older and often cheaper inventory costs flow into COGS first, producing lower expenses and higher gross profit when prices are rising. Under LIFO (last-in, first-out), the most recent and typically higher costs hit COGS first, reducing reported profit. When inventory loses value because of damage, obsolescence, or a drop in market price, GAAP requires a write-down to the lower of cost or net realizable value. That write-down flows through as an increase to COGS or as a separate loss line. Abnormal spoilage and wasted materials are charged to expense immediately rather than folded into inventory.
Operating Expense Accounts
Operating expenses cover the indirect costs of running the business, the ones not tied to producing a specific product. They are often grouped under selling, general, and administrative expenses, or SG&A. Gross profit minus operating expenses gives you operating income, which shows how the core business performs before financing and taxes enter the picture.
Selling, General, and Administrative Accounts
Administrative salaries compensate management, human resources, accounting staff, and other employees who keep the business functioning but do not work on production lines. Rent and occupancy accounts track office space, warehouses, and utilities. Marketing and advertising accounts capture spending on campaigns, public relations, and brand development. Insurance premiums for general liability, property coverage, and workers’ compensation land here as well.
Depreciation and Amortization
Depreciation allocates the cost of physical assets like equipment, vehicles, and buildings across their useful lives. Amortization does the same for intangible assets such as patents, trademarks, and software licenses. Both accounts reduce taxable income without requiring an immediate cash outflow.
Research and Development
Companies that invest in new products or technologies report those costs through R&D expense accounts. Under GAAP, most R&D spending is expensed as incurred rather than capitalized. That includes salaries for R&D personnel, contract research fees, and the cost of materials consumed during development. Equipment and facilities used in R&D can be capitalized only if they have an alternative future use beyond the current project. Otherwise, those costs hit the income statement immediately.
Credit Loss Expense
When a company extends credit to customers, some receivables will go unpaid. The credit loss expense account, sometimes still called bad debt expense, reflects management’s estimate of expected losses on outstanding receivables. Under the current expected credit loss (CECL) model, companies record an allowance as soon as a receivable is created rather than waiting for a customer to default. Changes to that estimate flow through as credit loss expense, which can create noticeable volatility when economic forecasts shift.
Non-Operating Revenue and Expense Accounts
Below operating income, the income statement separates financial activity that falls outside the company’s primary business. Keeping these items apart lets readers judge the core operation without the noise of financing decisions or one-time events.
Interest Income and Interest Expense
Interest income tracks money earned on bank deposits, short-term investments, or notes receivable. Interest expense records the cost of borrowing through loans, lines of credit, or bonds. A manufacturer’s interest expense tells you about its capital structure, not how well it makes widgets, which is why these accounts sit below the operating income line.
Gains and Losses on Asset Sales
When a company sells a long-term asset for more than its book value, the difference is recorded as a gain on sale. If the asset sells for less than book value, the shortfall appears as a loss on disposal. These events are one-off by nature and do not reflect the ongoing earning power of the business.
Foreign Currency Transaction Gains and Losses
Companies that operate internationally often hold receivables, payables, or cash balances denominated in foreign currencies. When exchange rates shift between the transaction date and the settlement date, the resulting gain or loss flows through the income statement. Some companies classify these within operating income if they relate to core activities like sales and purchasing. Others group them with non-operating items. Either approach is acceptable under GAAP as long as the method is applied consistently and disclosed.
Income Tax Accounts
The income tax provision has two components: current tax expense and deferred tax expense.
Current tax expense represents what the company expects to owe taxing authorities for the current period, calculated by applying tax law to the period’s taxable income. For C-corporations, the federal rate is a flat 21% of taxable income.1Office of the Law Revision Counsel. 26 USC 11 – Tax Imposed Pass-through entities like S-corporations, partnerships, and sole proprietorships do not pay corporate tax; the income flows to the owners’ individual returns and is taxed at their personal rates. State corporate income taxes vary widely, from zero in states that impose no corporate tax to over 11% in states with the highest brackets.
Deferred tax expense captures the future tax consequences of timing differences between book income and taxable income. If a company uses straight-line depreciation on its income statement but accelerated depreciation on its tax return, for example, the difference creates a deferred tax liability that will reverse in later years. That future obligation shows up as deferred tax expense in the current period. Together, the current and deferred portions make up the total income tax provision.
Net Income and Earnings Per Share
After subtracting the income tax provision from pre-tax income, you arrive at net income, or net loss if expenses exceeded revenue. This is the bottom line, the single number that tells you whether the business made money during the period. Positive net income can be reinvested into the business or distributed to owners as dividends. A net loss reduces the company’s equity.
Net income does not stop at the income statement. It flows into the statement of retained earnings and updates the equity section of the balance sheet. That link is one reason accuracy in every income statement account matters: an error anywhere on the statement cascades into the balance sheet.
Publicly traded companies must also report earnings per share (EPS) on the face of the income statement. Basic EPS divides net income (after subtracting any preferred stock dividends) by the weighted-average number of common shares outstanding. Diluted EPS goes further by assuming that all potentially dilutive securities, such as stock options, warrants, and convertible debt, were converted into common shares. Both figures are required for each period presented.
Special Accounts You May See
A handful of accounts appear on income statements only in specific circumstances. They belong to the statement but sit outside the main revenue-to-net-income flow.
Discontinued Operations
When a company shuts down or sells off a major line of business, the results of that segment are pulled out of the regular income categories and reported separately as discontinued operations. This line appears below income from continuing operations, net of its own tax effect, so readers can see what the ongoing business earned without distortion from the wind-down. Under current GAAP, a disposal only lands here if it represents a strategic shift that has, or will have, a major effect on the company’s operations and financial results. Selling a minor product line or closing a single location typically would not qualify.
Unusual and Infrequent Items
GAAP used to have a category called extraordinary items for events that were both unusual and infrequent, reported net of tax below the operating section. That concept was eliminated in 2015. Now, unusual or infrequent gains and losses are reported as a separate line item within income from continuing operations, before tax, with a description of what caused them. Natural disaster losses, large litigation settlements, or the write-off of a major asset fit here. They get their own line so readers can distinguish them from recurring activity, but they no longer receive special net-of-tax treatment below the line.
Other Comprehensive Income
Other comprehensive income (OCI) technically appears on the statement of comprehensive income rather than the traditional income statement, but the two are often presented together, either as a single continuous statement or as two consecutive statements. OCI captures gains and losses that bypass net income entirely under GAAP. The most common items include unrealized gains and losses on certain investments, foreign currency translation adjustments from consolidating foreign subsidiaries, and changes in the funded status of pension and other post-retirement benefit plans. These amounts accumulate in a separate equity account on the balance sheet called accumulated other comprehensive income. A company can report strong earnings while simultaneously absorbing large unrealized losses on its investment portfolio, so OCI often carries information the income statement alone does not.
How the Accounts Stack
The order of the accounts on an income statement is what gives the statement its analytical power. Revenue minus cost of goods sold equals gross profit. Gross profit minus operating expenses equals operating income. Operating income plus or minus non-operating items equals pre-tax income. Pre-tax income minus income taxes equals net income. Each subtotal answers a different question about the business, and each account feeds into the next. Follow the stack and you can trace exactly where a company’s profits came from, or where they disappeared.
