A Profit and Loss Statement (also called an income statement, P&L, or statement of operations) is a financial document that summarizes a business's revenues, costs, and expenses over a specific reporting period to show whether the business operated at a profit or a loss. It is one of the three core financial statements required under Generally Accepted Accounting Principles (GAAP), alongside the balance sheet and cash flow statement.

The Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 225 establishes the framework for income statement presentation. For publicly traded companies, SEC Regulation S-X (17 CFR 210) prescribes specific line items and disclosures required in P&L statements filed with quarterly (10-Q) and annual (10-K) reports. While private businesses are not subject to SEC requirements, lenders, investors, and courts routinely expect P&L statements prepared in accordance with GAAP or, for smaller businesses, in accordance with the cash or modified cash basis of accounting.

For sole proprietors and single-member LLCs, the IRS requires P&L information to be reported on Schedule C (Form 1040), which calculates net profit or loss from business operations. Partnerships file Form 1065, and S-corporations file Form 1120-S, both of which require detailed income and expense reporting that mirrors the structure of a P&L statement. Accurate P&L preparation is essential not only for tax compliance but also for loan applications, business valuations, insurance claims, and legal proceedings such as divorce asset division or business dispute litigation.

Business loan applications and lines of credit require P&L statements as part of the underwriting process. Banks, SBA lenders, and alternative lenders typically request two to three years of historical P&L statements plus year-to-date figures to assess a business's ability to service debt. Without accurate P&L documentation, loan applications are routinely denied.

Tax preparation for any business entity requires P&L data. Sole proprietors need it for Schedule C, partnerships for Form 1065, and corporations for Form 1120 or 1120-S. IRS audits frequently focus on income and expense substantiation, making a well-documented P&L statement with supporting records essential for audit defense.

Investors evaluating potential investments, whether venture capital, angel investing, or business acquisition, rely on P&L statements to assess profitability trends, margin analysis, and operational efficiency. Divorce proceedings involving a business-owner spouse require P&L statements for business valuation and income determination for spousal and child support calculations. Franchise applications, lease negotiations for commercial space, and insurance claims for business interruption all require current P&L documentation.

Revenue (or gross sales) is the top line, representing total income from the sale of goods or services before any deductions. Net revenue subtracts returns, allowances, and discounts from gross revenue. The reporting period must be clearly stated, whether monthly, quarterly, or annually, and should be consistent across periods for comparability.

Cost of Goods Sold (COGS) includes all direct costs attributable to producing the goods or services sold, including materials, direct labor, and manufacturing overhead. Gross profit is calculated as revenue minus COGS and represents the margin available to cover operating expenses.

Operating expenses are categorized into selling, general, and administrative (SG&A) expenses, including rent, salaries, marketing, insurance, depreciation, and utilities. Operating income (EBIT) is gross profit minus operating expenses and measures profitability from core business operations.

Non-operating items include interest income, interest expense, gains or losses from asset sales, and other items outside normal business operations. Net income before taxes, income tax provision, and net income after taxes are the bottom-line figures that determine the business's overall profitability. The preparer's name, accounting method (cash, accrual, or modified cash), and any notes explaining significant items or accounting policy changes should accompany the statement.
