FASB vs GAAP: What’s the Difference? | Accountant Compass

What Is the Difference Between FASB and GAAP?

The main difference between FASB and GAAP is that FASB is a standard-setting organization, while GAAP is the body of accounting principles and authoritative guidance used to prepare financial statements.

FASB stands for the Financial Accounting Standards Board (FASB). It develops and improves financial accounting and reporting standards for public companies, private companies, and not-for-profit organizations that follow U.S. GAAP.

GAAP stands for Generally Accepted Accounting Principles. GAAP is not an organization. It is the accounting guidance used to determine how transactions and events should be recognized, measured, presented, and disclosed.

The easiest memory rule is simple: FASB is the standard setter; GAAP is the accounting guidance.

That makes FASB vs GAAP very different from GAAP vs IFRS. GAAP and IFRS are different reporting frameworks. FASB and GAAP are not competing alternatives.

What Is FASB?

The Financial Accounting Standards Board is an independent, private-sector, not-for-profit organization that establishes financial accounting and reporting standards for public and private companies and not-for-profit organizations that follow GAAP.

FASB was established in 1973. It has seven full-time Board members and is supported by more than 60 professionals with backgrounds that include accounting, investing, finance, business, education, and research, according to FASB. Those details reinforce an important point: FASB is an institution, not a set of accounting rules.

What Does FASB Do?

FASB identifies financial reporting problems, researches possible solutions, deliberates proposed changes, seeks stakeholder feedback, and issues amendments when the Board concludes that GAAP should change.

Stakeholder input is a significant part of that process. According to the FASB 2025 Investor Outreach Report, the Board recorded more than 2,100 investor interactions from 2021 through the fiscal year ended June 30, 2025. Its 2024 agenda consultation included discussions with about 200 stakeholders, almost one-third of whom were investors.

“Investor views will continue to help us ensure that we address the right priorities.” Richard R. Jones, FASB Chair, and Jackson M. Day, FASB Technical Director — FASB 2025 Investor Outreach Report

Is FASB a Government Agency?

No. FASB is a private-sector organization, not a federal government agency.

The Securities and Exchange Commission has statutory authority over accounting and financial reporting by companies and other entities that file with the Commission. The SEC recognizes FASB as the designated private-sector standard setter while retaining its own legal authority. See the SEC policy statement recognizing FASB.

What Is GAAP?

GAAP, or Generally Accepted Accounting Principles, is the body of accounting principles and authoritative guidance used in U.S. financial reporting.

GAAP creates a common basis for reporting financial information. It helps entities account for similar economic events using consistent requirements, which makes financial statements easier to understand and compare.

GAAP covers detailed areas such as revenue, inventory, leases, financial instruments, liabilities, business combinations, cash flows, and financial statement presentation. For a broader map of the framework, visit the U.S. GAAP learning and research hub.

Is GAAP an Organization?

No. GAAP is not a board, agency, regulator, or professional association. FASB has Board members, staff, meetings, research projects, and standard-setting procedures. GAAP does not. GAAP is the accounting guidance that an entity applies.

Why Does GAAP Matter?

GAAP matters because users of financial statements need information prepared on a consistent basis. Investors, lenders, auditors, managers, and other users need to understand what reported numbers mean and compare them across periods and companies.

“getting the accounting right is vital to consistency and comparability for investors.” Paul Munter, then-SEC Chief Accountant — SEC remarks, Dec. 9, 2024

Does Every U.S. Business Have to Follow GAAP?

No. Not every U.S. business has the same GAAP reporting obligation.

SEC registrants generally must comply with applicable U.S. GAAP and SEC reporting requirements, subject to specific rules and exceptions. Private companies may also prepare GAAP financial statements because lenders, investors, owners, contracts, or other users require them. A small privately held business may use another accounting basis for some internal or tax purposes, but that does not make the alternative basis U.S. GAAP.

What Is the Relationship Between FASB and GAAP?

FASB and GAAP are connected because FASB establishes and updates standards that form authoritative U.S. GAAP for nongovernmental entities.

A company therefore does not normally ask, “Should we follow FASB or GAAP?” It follows the accounting guidance that applies to its financial statements. When accountants research current nongovernmental U.S. GAAP, they generally work through the FASB Accounting Standards Codification.

How Does FASB Turn an Accounting Issue Into New Guidance?

FASB uses a structured standard-setting process. At a high level, the Board identifies a financial reporting issue, decides whether to add a project to its agenda, deliberates the issue in public meetings, exposes proposed guidance for comment, evaluates stakeholder input, redeliberates the proposal, and may then issue an Accounting Standards Update describing amendments to the Codification.

For more detail, see the official FASB standard-setting process.

Does FASB Create GAAP?

Yes, for nongovernmental U.S. financial reporting, FASB establishes and amends standards that become part of authoritative GAAP. But the statement needs an important qualification.

FASB is not the only institution involved in U.S. financial reporting. The SEC has statutory authority over accounting and reporting by SEC registrants and recognizes FASB as the designated private-sector standard setter.

Who Sets GAAP in the United States?

There is no single answer for every type of entity. For nongovernmental entities, FASB is the primary private-sector standard setter. For U.S. state and local governments, the Governmental Accounting Standards Board (GASB) establishes accounting and financial reporting standards for governments that follow GAAP.

Federal governmental entities generally use GAAP developed through the Federal Accounting Standards Advisory Board (FASAB).

Where Is GAAP Actually Found? Understanding the FASB Codification

For nongovernmental entities, authoritative U.S. GAAP is organized in the FASB Accounting Standards Codification, commonly called the ASC or FASB Codification.

FASB describes the Codification as the authoritative source of nongovernmental U.S. GAAP, while SEC-issued rules and regulations also apply to SEC registrants. See the official FASB standards and Codification information.

Instead of searching through decades of disconnected accounting pronouncements, accountants can research current guidance through an organized system of Topics, Subtopics, Sections, and paragraphs.

What Is the ASC?

ASC stands for Accounting Standards Codification. Common examples include ASC 230 for the Statement of Cash Flows, ASC 330 for Inventory, ASC 606 for Revenue from Contracts with Customers, and ASC 842 for Leases.

If an accountant faces a revenue question, the question is not “Should I use FASB or GAAP?” It is “Which GAAP guidance applies?” For a contract with a customer, that research may lead to ASC 606.

Is the FASB Codification the Same as GAAP?

The Codification is not a separate accounting framework from GAAP. It is the organized authoritative source of nongovernmental U.S. GAAP.

For the Codification’s general principles and authority hierarchy, continue to ASC 105, Generally Accepted Accounting Principles.

What Is an Accounting Standards Update?

An Accounting Standards Update, or ASU, communicates changes to the FASB Codification, but the ASU itself is not an authoritative accounting standard.

FASB explains that an ASU communicates amendments, why they were made, when they become effective, and how entities transition to the new requirements. The current authoritative guidance is reflected in the Codification. See the official Accounting Standards Updates page.

ASC vs ASU

How Does FASB Change GAAP?

FASB changes nongovernmental GAAP through its standard-setting process. After research, public deliberation, stakeholder feedback, and redeliberation, the Board may issue an ASU describing amendments. Those amendments are incorporated into the Codification.

This is why accountants must verify current guidance. An old ASU, article, textbook, or training document may describe a rule that has since been amended.

FASB vs GAAP Example: Revenue Recognition

Revenue recognition shows the relationship clearly: FASB develops and amends the accounting standard, while companies apply the resulting GAAP guidance contained in the Codification.

The accountant would examine the applicable requirements, including matters such as the contract, performance obligations, transaction price, and when those obligations are satisfied. The relationship is therefore: FASB develops the standard → the ASC contains the authoritative guidance → the company applies GAAP to the transaction.

For a full treatment of the model, see our ASC 606 Revenue Recognition guide.

Common FASB vs GAAP Misconceptions

The most common mistake is treating FASB and GAAP as competing accounting systems. They are not.

Misconception 1: “FASB Accounting vs GAAP Accounting”

There is no ordinary choice between “FASB accounting” and “GAAP accounting” in the way an entity might compare U.S. GAAP with IFRS. FASB and GAAP sit within the same U.S. financial reporting ecosystem.

Misconception 2: “FASB Standards and GAAP Standards Are Separate Rulebooks”

The wording can appear in casual discussion, but it should not suggest two independent systems. For nongovernmental entities, the current authoritative guidance is organized in the FASB Codification.

Misconception 3: “GAAP Is Just a Short List of Principles”

GAAP includes detailed authoritative requirements across many accounting topics. Broad concepts can help explain accounting, but real GAAP research often requires locating detailed guidance in the relevant ASC Topic. For the conceptual foundation behind reporting, see our guide to financial reporting concepts.

FASB vs GAAP vs ASC vs ASU: Quick Reference

FASB is the standard setter, GAAP is the accounting guidance, the ASC codifies authoritative nongovernmental GAAP, and an ASU communicates amendments to that Codification.

A useful memory shortcut is: FASB sets standards. GAAP is the guidance. ASC organizes authoritative GAAP. ASUs communicate changes.

Frequently Asked Questions About FASB and GAAP

FASB vs GAAP in Simple Terms

The simplest way to remember FASB vs GAAP is this: FASB is the organization that establishes and improves accounting standards for nongovernmental U.S. entities, while GAAP is the body of accounting guidance those entities apply.

The ASC connects the two by organizing authoritative nongovernmental U.S. GAAP. When FASB changes that guidance, an ASU communicates the amendments and the Codification is updated.

So do not think of FASB and GAAP as competing systems. Think of them as different roles within the same reporting structure: FASB sets standards, the ASC codifies them, and reporting entities apply GAAP.
