The 10 GAAP principles are regularity, consistency, sincerity, permanence of methods, non-compensation, prudence, continuity, periodicity, materiality, and utmost good faith. They are the widely taught summary of the reasoning behind Generally Accepted Accounting Principles in the United States, the standardized rules U.S. companies use to prepare financial statements so investors, lenders, and regulators can compare one company to another. The formal, technical rules live in the Financial Accounting Standards Board’s Accounting Standards Codification; the ten principles distill the spirit of those rules into ideas an accountant, auditor, or business owner can actually hold in their head.1Financial Accounting Standards Board. About the FASB
The 10 Principles, One by One
Regularity
Accountants follow the established rules consistently. GAAP compliance is treated as a baseline professional obligation, not a suggestion an accountant can set aside when a client would prefer a different answer.
Consistency
A company uses the same accounting methods from one reporting period to the next, so year-over-year comparisons actually mean something. If a company does change a method, it has to disclose the change and justify it, so readers can tell whether a shift in the numbers reflects the business or the bookkeeping.
Sincerity
Financial statements present an accurate, unbiased picture of the company’s position. The accountant’s goal is to reflect reality, not to dress the numbers up or talk them down.
Permanence of Methods
Reporting procedures stay stable over time. This principle overlaps with consistency but focuses on the mechanics: the same procedures, applied the same way, so trends over multiple years are readable at a glance.
Non-Compensation
A company reports all positives and negatives in full rather than netting them against each other. A debt cannot simply be subtracted from an asset to hide either one. Good news and bad news show up separately, at their full size.
Prudence
Financial data relies on verifiable facts, not speculation. When uncertainty exists, the more cautious estimate is preferred: assets are not inflated, and liabilities are not minimized. This is why, for example, GAAP generally records assets at historical cost rather than at a speculative current market value. A building bought for $500,000 twenty years ago stays on the books at that cost, less accumulated depreciation, even if it might now sell for far more.
Continuity
Also called the going concern assumption, this principle presumes the business will keep operating for the foreseeable future. That assumption changes how long-term assets and liabilities are valued. If continuity no longer holds, the accountant has to say so, because a company that may not survive the year is not valued the same way as one that expects to keep trading.
Periodicity
Financial activity is broken into defined time intervals such as quarters and fiscal years. Stakeholders get timely, regular updates rather than waiting indefinitely for a complete picture. This is the reason quarterly reports and annual reports exist as fixed, recurring documents.
Materiality
Any financial information significant enough to influence a reader’s decision has to be disclosed. Small, immaterial items can be simplified or grouped together, but nothing important gets left out. Materiality is judgment-based, and auditors spend a lot of their time deciding where the line sits for a given company.
Utmost Good Faith
Everyone involved in the accounting process, from the bookkeeper up to the CFO and the outside auditor, is expected to act honestly and transparently, without intent to mislead. This principle underpins the others: if the people preparing the numbers are not acting in good faith, no rule about revenue recognition or depreciation is going to save the resulting statements.
How the 10 Principles Relate to Actual GAAP Rules
The ten principles are not a formal list published by the FASB. The official standards sit in the Accounting Standards Codification (ASC), the single collection the FASB maintains as the authoritative source for GAAP outside of SEC rules.1Financial Accounting Standards Board. About the FASB Accounting education and reference materials use the ten-principle framework because it captures the reasoning behind those detailed standards in language a non-specialist can follow.
You can see the principles at work in the concrete requirements companies actually apply. Accrual basis accounting, which records income and expenses when they are earned or incurred rather than when cash changes hands, is periodicity and sincerity in practice: revenue for a December delivery belongs on the December statements even if the check arrives in January. The five-step revenue recognition process under ASC 606, which walks from identifying a contract through recognizing revenue as each promise is satisfied, is consistency and prudence in operational form. And ASC 842, which requires companies to put both operating and finance leases on the balance sheet as a right-of-use asset and a matching obligation, is non-compensation applied to lease commitments that used to sit off the books.2Financial Accounting Standards Board.

The FASB’s authority to set these standards for public companies comes from the Securities and Exchange Commission. The Sarbanes-Oxley Act of 2002 formalized that arrangement by allowing the SEC to recognize accounting principles established by a qualified private-sector body, and the SEC retains ultimate authority over the content of financial statements filed under the federal securities laws.3GovInfo.

One boundary worth noting: state and local governments do not follow FASB GAAP. They follow a separate but parallel set of standards issued by the Governmental Accounting Standards Board.6Governmental Accounting Standards Board. Summary – Statement No 34 The ten principles described here are the FASB tradition and apply to companies and nonprofits, not to public-sector entities.
Who Actually Has to Follow the 10 Principles
Public companies, meaning those with securities registered under the Securities Exchange Act, are legally required to prepare their financial statements under GAAP when filing with the SEC. That includes annual reports on Form 10-K and quarterly reports on Form 10-Q.4U.S. Securities and Exchange Commission. Policy Statement: Reaffirming the Status of the FASB as a Designated Private-Sector Standard Setter For these companies, all ten principles are effectively mandatory, because the detailed ASC rules they enforce are built on those principles.
Private companies are not legally required to follow GAAP, but many do voluntarily. Banks and lenders frequently require GAAP-compliant audited financial statements as a condition of commercial loans, and debt covenants often reference GAAP-based financial ratios such as interest coverage, debt-to-earnings, and minimum net worth. A private company that does not follow GAAP can struggle to secure financing or attract investors who want reliable, standardized data.
Nonprofit organizations also follow GAAP, though with some adaptations. Nonprofits classify their net assets based on whether donor restrictions exist, and their financial statements use terminology suited to organizations without shareholders or a profit motive.7Financial Accounting Standards Board. Summary of Statement No 117 The ten underlying principles still apply.
What Happens When the Principles Are Violated
Companies and accounting professionals that violate GAAP face real consequences. The SEC enforces compliance through a tiered civil penalty structure that adjusts annually for inflation. As of the most recent adjustment, penalties for entities start at roughly $118,000 per violation for basic infractions and can exceed $1.1 million per violation when fraud causes substantial losses to investors.8U.S. Securities and Exchange Commission. Adjustments to Civil Monetary Penalty Amounts Individual accountants and officers face lower per-violation amounts but can also be barred from serving as officers or directors of public companies.
Actual settlements for major violations run well above those minimums. In 2024, UPS agreed to pay $45 million to settle SEC charges that it had materially misrepresented its earnings by failing to follow GAAP when valuing one of its business units. The settlement also required the company to hire an independent compliance consultant and put new training in place for officers and directors.9U.S. Securities and Exchange Commission.

Audit firms face their own enforcement from the PCAOB, which can impose censures, fines, and mandatory remedial training. In 2024, PricewaterhouseCoopers was fined $2.75 million for quality control violations related to independence requirements.10PCAOB Public Company Accounting Oversight Board. All Enforcement Updates Ernst & Young paid $100 million in 2022 after the SEC found that a significant number of its audit professionals had cheated on CPA ethics exams, including exams designed to test knowledge of GAAP compliance.11U.S. Securities and Exchange Commission. Ernst and Young to Pay $100 Million Penalty for Employees Cheating on CPA Ethics Exams and Misleading Investigation That last case cuts straight to the utmost good faith principle: without it, the rest of the framework does not hold.
Beyond government enforcement, companies that restate financial results because of GAAP failures often face shareholder lawsuits, a drop in stock price, and loss of access to capital markets. For public companies, repeated or serious violations can lead to delisting from stock exchanges, cutting off access to public investors entirely.
