GASB and GAAP aren’t two competing systems. GASB, the Governmental Accounting Standards Board, writes the version of GAAP (generally accepted accounting principles) that state and local governments must follow, while the Financial Accounting Standards Board (FASB) writes the version that applies to companies and nonprofits. So the real difference between GASB and GAAP is a category error in the question itself: GASB standards are GAAP, just the governmental branch of it.
GAAP Is a Framework, Not a Single Rulebook
When financial statements are described as “prepared in accordance with GAAP,” it means they follow the authoritative accounting standards for that entity’s sector. Which standard-setter wrote those rules depends on what the entity is.
- FASB, established in 1973, sets standards for public and private companies and not-for-profit organizations.1Financial Accounting Standards Board. About the FASB
- GASB, established in 1984, sets standards for state and local governments.2Governmental Accounting Standards Board (GASB). About the GASB
- The Federal Accounting Standards Advisory Board (FASAB) sets standards for federal agencies and departments.3USAGov. Federal Accounting Standards Advisory Board
The AICPA’s Council has formally designated GASB as the body that establishes financial accounting principles for state and local governmental entities. Under the AICPA’s Accounting Principles Rule, GASB pronouncements are the authoritative GAAP that CPAs must follow when auditing or preparing governmental financial statements.4AICPA. AICPA Code of Professional Conduct A city’s audited financials and a corporation’s audited financials are both “GAAP-compliant.” They just answer to different rulebooks within GAAP.
Why Governments Use a Different Version of GAAP
The split exists because governments and businesses exist for different reasons, and their financial statements are asked different questions.
A corporation exists to generate profit. Its statements help investors and creditors judge whether the business can produce future cash flows and stay solvent. FASB standards focus on net income, total assets and liabilities, and changes in equity. This is called the economic resources measurement focus.
Governments don’t exist to earn a profit. They collect taxes and fees to provide services, and their statements need to show whether public money was spent lawfully and within the approved budget. GASB’s framework is built around fiscal accountability: did the government raise enough revenue this year to cover this year’s costs, and did it follow the spending plan legislators approved?
GASB’s Concepts Statement No. 1 captures this through the principle of interperiod equity, which holds that financial reporting should help users assess whether current-year revenues are sufficient to pay for current-year services, or whether future taxpayers will be required to bear the burden of services already provided.5Governmental Accounting Standards Board (GASB). Summary of Concepts Statement No 1 That concern doesn’t exist in private-sector accounting, where the question is whether the business created value for shareholders.
Where Government Statements Actually Look Different
If you compare a city’s annual financial report with a corporation’s, three structural differences stand out. All three come from GASB standards, and none of them appear in FASB’s version of GAAP.
Two Layers of Reporting Instead of One
GASB Statement No. 34, the foundational standard for modern governmental reporting, requires the basic financial statements to include both government-wide statements and fund statements.6Governmental Accounting Standards Board (GASB). Summary – Statement No 34 A corporation issues one set of statements under one basis of accounting. A government issues two.
The government-wide statements use the full accrual basis and the economic resources measurement focus, the same approach a business uses. They report all assets, liabilities, revenues, and expenses, including capital assets like roads and buildings and long-term debts like bonds payable. They separate governmental activities (funded mainly by taxes) from business-type activities (funded mainly by user fees). This is the closest thing to a corporate balance sheet and income statement, and it answers whether the government is better off financially than it was last year.
The fund statements break the government’s activities into individual funds, each a separate accounting and fiscal entity with its own books. The fund structure exists because governments must track whether legally restricted resources are being spent for their intended purposes. Money voters approved for a school bond cannot be spent on police salaries, and the fund structure enforces that separation.
Modified Accrual Accounting
Governmental funds, including the general fund, use the modified accrual basis of accounting and the current financial resources measurement focus.6Governmental Accounting Standards Board (GASB). Summary – Statement No 34 This is the biggest technical departure from private-sector accounting. Under modified accrual, revenues are recognized only when they are both measurable and available to pay current-period obligations.7Governmental Accounting Standards Board (GASB). Summary – Statement No 33 “Available” means the government has already collected the money or expects to collect it soon enough after year-end to cover liabilities from the current period. Long-term assets and long-term debts are excluded from these fund balance sheets entirely, because the point is to show what resources are on hand right now.
Proprietary funds (activities that operate like businesses, such as a municipal water system) and fiduciary funds (assets the government holds for others, such as a pension trust) use full accrual instead.6Governmental Accounting Standards Board (GASB). Summary – Statement No 34
Pension and OPEB Liabilities on the Balance Sheet
GASB Statement No. 68 requires governments to recognize their net pension liability directly on the government-wide statements. That liability is the difference between the total projected pension obligation to current and former employees and the assets available in the pension fund to pay it.8Governmental Accounting Standards Board (GASB). Summary – Statement No 68 GASB Statement No. 75 imposes a parallel requirement for other postemployment benefits like retiree health insurance, using the same approach of total projected benefits minus plan assets.9Governmental Accounting Standards Board (GASB). Summary – Statement No 75
Before these standards took effect, many governments disclosed pension and OPEB obligations only in footnotes. Moving them onto the face of the financial statements changed the picture dramatically. Some governments saw their reported net position swing from positive to deeply negative once unfunded pension and OPEB liabilities hit the balance sheet.
Who Has to Follow GASB
GASB standards apply to all state governments and all general-purpose local governments, including counties, cities, towns, and villages.2Governmental Accounting Standards Board (GASB). About the GASB They also apply to special-purpose governmental entities like public school districts, public hospitals, transit authorities, and government-owned utilities. The signs that an entity falls under GASB rather than FASB are usually the popular election of its leadership or governing board and the power to levy taxes.
An entity that receives public funding but doesn’t have those governmental characteristics, such as a private nonprofit that gets government grants, typically follows FASB standards instead. The line can get blurry with quasi-governmental organizations and public benefit corporations, where the determination often depends on how much control the government exercises over the entity’s operations and governance.
How GASB Compliance Gets Enforced
State and local governments aren’t regulated by the SEC the way public companies are, so there’s no federal securities regulator forcing them to follow GASB. Enforcement runs through three other channels.
Auditors are the first. CPAs must follow AICPA professional standards, which designate GASB pronouncements as the authoritative GAAP for governmental entities. A CPA who issues a clean audit opinion on government financial statements that don’t follow GASB standards is violating professional ethics rules.4AICPA. AICPA Code of Professional Conduct
Federal funding is the second. Governments that spend $1,000,000 or more in federal awards during a fiscal year must undergo a Single Audit, which requires the auditor to determine whether the statements are presented fairly in accordance with GAAP.10eCFR. 2 CFR Part 200 Subpart F – Audit Requirements Governments that fail to produce GAAP-compliant financials put federal funding eligibility at risk.
The bond market is the third. Credit rating agencies have long treated failure to conform with GAAP as a negative factor in municipal bond ratings. A lower credit rating means higher borrowing costs, and for a government issuing hundreds of millions in bonds, even a small rate increase translates into real money paid by taxpayers.
