How to Approach U.S. GAAP Research
Good accounting research starts with the facts, not the Topic number. Use this three-step process to move from the business issue to current authoritative guidance.
1. Define the accounting issue
Identify the transaction, reporting question, entity type, financial statement impact, and the period being analyzed.
2. Identify the relevant ASC Topic
Use the transaction facts and accounting objective to locate the Topic, then review scope, definitions, recognition, measurement, and disclosure requirements.
3. Verify current authoritative guidance
Check current paragraph-level guidance, Accounting Standards Updates, effective dates, transition provisions, exceptions, and entity-specific requirements.
Use Educational Guides With Authoritative Research

Frequently Asked Questions About U.S. GAAP
Quick answers to common questions about U.S. GAAP, FASB authority, the Codification, and accounting research.
What is U.S. GAAP?
U.S. GAAP is the body of generally accepted accounting principles used for financial reporting in the United States. It includes authoritative guidance on recognition, measurement, presentation, and disclosure for transactions and financial statement items.
Who sets U.S. GAAP?
For nongovernmental entities, the Financial Accounting Standards Board develops and improves accounting standards. The SEC also has legal authority over financial reporting by U.S. public companies and recognizes FASB as the private-sector accounting standard setter.
What is the FASB Accounting Standards Codification?
The Accounting Standards Codification, or ASC, is the organized source of authoritative nongovernmental U.S. GAAP. It arranges guidance by Topic, Subtopic, Section, and paragraph so researchers can locate requirements for specific accounting issues.
What is the difference between U.S. GAAP and the ASC?
U.S. GAAP refers to the authoritative accounting framework, while the ASC is the structure used to organize authoritative nongovernmental U.S. GAAP. In practice, researchers use ASC Topics to locate the specific accounting guidance that applies to an issue.
What are recognition and measurement under U.S. GAAP?
Recognition determines when an item should be included in the financial statements. Measurement determines the amount at which that item is recorded or reported. Different ASC Topics can use different measurement bases depending on the accounting issue.
How are presentation and disclosure different?
Presentation concerns where and how information appears in the financial statements. Disclosure provides additional information in the notes, including accounting policies, assumptions, risks, reconciliations, and other details required by applicable guidance.
Is U.S. GAAP the same as tax accounting?
No. U.S. GAAP is designed for financial reporting, while tax accounting follows tax laws and regulations. Because the objectives and rules differ, the same transaction can have different book and tax treatments.
How should I research a U.S. GAAP issue?
Start by defining the transaction and accounting question. Then identify the relevant ASC Topic, confirm scope, review recognition and measurement guidance, evaluate presentation and disclosure requirements, and verify current amendments and effective dates.
