What Is GAAP in Accounting?

GAAP stands for Generally Accepted Accounting Principles. It is a collection of standardized accounting rules, principles, and procedures used to prepare financial statements in the United States.

When people ask what is GAAP in accounting, the simplest answer is that GAAP provides a common language for financial reporting. It ensures that financial statements from different companies can be understood, compared, and trusted.

GAAP covers:

• Revenue recognition
• Expense reporting
• Asset valuation
• Financial statement presentation
• Disclosure requirements

These standards reduce ambiguity and promote transparency.

Who Sets GAAP Standards?

The Financial Accounting Standards Board (FASB) is the independent organization responsible for establishing GAAP in the United States. FASB operates under the oversight of the Securities and Exchange Commission (SEC).

Understanding who defines the rules clarifies what is GAAP in accounting at a regulatory level.

According to the SEC, GAAP compliance strengthens capital markets and reduces financial fraud risks.
