Government Accounting Terms and Definitions: Funds, ACFR, Yellow Book

Government accounting terms describe a system built for public accountability rather than profit, and the vocabulary reflects that purpose. Where private-company accounting revolves around revenue, expenses, and earnings, government accounting revolves around funds, appropriations, and whether public money was spent as authorized. Learning the core terms below will let you read a city, county, school district, or state agency’s financial report and understand what it is actually saying.

Why the Vocabulary Is Different

State and local governments follow rules set by the Governmental Accounting Standards Board (GASB), established in 1984, rather than the Financial Accounting Standards Board (FASB) rules used by private companies. Both boards sit under the Financial Accounting Foundation, but they answer different questions. FASB standards help investors evaluate profitability. GASB standards help citizens, bondholders, and oversight bodies evaluate whether a government is managing public resources responsibly and staying within its legal spending authority.1Governmental Accounting Standards Board. About the GASB

That difference in purpose is why the terms don’t line up with private-sector accounting. Governments don’t measure profit because they aren’t trying to generate it. The vocabulary is built to answer whether revenue came in as expected, whether spending stayed within the approved budget, and whether restricted money went only to its designated purpose.

Fund

Fund is the term everything else hangs on. GASB defines a fund as a fiscal and accounting entity with a self-balancing set of accounts, segregated to carry on specific activities or meet certain objectives in accordance with regulations and restrictions.2National Center for Education Statistics. Financial Accounting for Local and State School Systems 2014 Edition – Chapter 4 Governmental Accounting Fund Structure In plain terms, a government splits its money into separate pots, and each pot has its own assets, liabilities, revenues, and expenditures. Money earmarked for one purpose stays in its own lane. If a state collects a motor fuel tax dedicated to road maintenance, that revenue sits in its own fund and cannot be quietly redirected to cover a shortfall elsewhere.

Funds fall into three categories.

Governmental Funds

Governmental funds cover the tax-supported activities most people associate with government: police, fire, public works, parks, and general administration. Within this category:

  • General Fund. The main operating fund. If revenue isn’t legally required to go somewhere else, it lands here.
  • Special Revenue Funds. Money that laws or regulations restrict to a particular purpose, such as a hotel occupancy tax dedicated to tourism promotion.
  • Capital Projects Funds. Money used to acquire or build major capital assets like buildings and infrastructure.
  • Debt Service Funds. Principal and interest payments on long-term government debt.
  • Permanent Funds. Resources where the principal must remain intact but earnings can be spent on programs that benefit the public.

Proprietary Funds

Proprietary funds cover activities that operate more like businesses, recovering costs through user fees. They track net income, total assets, and long-term liabilities the way private companies do.2National Center for Education Statistics. Financial Accounting for Local and State School Systems 2014 Edition – Chapter 4 Governmental Accounting Fund Structure There are two types. Enterprise funds account for services provided to the public for a fee, such as a city-owned water utility, a public airport, or a municipal golf course. Internal service funds account for services one government department provides to other departments on a cost-reimbursement basis, such as a centralized fleet maintenance shop or an in-house IT operation.

Fiduciary Funds

Fiduciary funds hold money the government manages on behalf of someone else. The government is a trustee or custodian, not the owner. Common examples are pension trust funds that manage employee retirement assets and custodial funds that hold tax collections before distributing them to other entities. Because this money doesn’t belong to the government, fiduciary fund resources are left out of the government-wide financial statements entirely.3Governmental Accounting Standards Board. Summary – Statement No. 34

Interfund Transfer and Interfund Loan

Money does move between funds, and the terms distinguish two ways it can happen. An interfund transfer is a permanent, one-way flow with no expectation of repayment. A general fund might transfer money to a capital projects fund to help finance a new fire station. Transfers appear as “other financing uses” in the sending fund and “other financing sources” in the receiving fund, kept separate from regular revenues and expenditures.

An interfund loan requires repayment. The lending fund records a receivable and the borrowing fund records a payable. If repayment becomes unlikely, the rules require reclassifying the loan as a transfer, which prevents governments from disguising permanent spending shifts as temporary borrowing.

Modified Accrual and Full Accrual

Basis of accounting is the term for when a transaction gets recorded, and government reports use two different bases depending on which statement you’re reading.

Full accrual works the same way it does in the private sector: revenues count when earned and expenses when incurred, regardless of when cash moves. It captures long-term assets like buildings and long-term liabilities like bond debt and pension obligations. Government-wide statements, proprietary funds, and fiduciary funds all use full accrual.3Governmental Accounting Standards Board. Summary – Statement No. 34

Modified accrual is the hybrid used by governmental funds, and it’s where government accounting diverges most sharply from the private sector. Revenues are recognized only when they are both measurable and available to pay current-period obligations. For property taxes, GASB sets the availability window at 60 days after the fiscal year ends.4Governmental Accounting Standards Board. Fact Sheet – Financial Reporting Model Improvements Capital purchases are treated differently too. When a government buys a fire truck, the full cost is recorded as an expenditure in the year of purchase, not capitalized and depreciated. Long-term debt works the reverse way and doesn’t appear as a liability on governmental fund statements at all. The focus is what’s spendable now, matching the annual budget cycle. The long-term picture shows up separately in the government-wide statements.

Appropriation, Encumbrance, and Budget-to-Actual

Budgets carry legal weight in government accounting. An adopted budget isn’t a planning document. It’s a legal authorization to spend, called an appropriation, and exceeding it can violate the law. Several terms exist specifically to enforce that authorization.

Encumbrance accounting reserves spending authority the moment a purchase commitment is made, before the invoice arrives. When a department issues a purchase order for $50,000 in equipment, that amount is immediately encumbered against the budget. The cash is still in the bank, but it’s spoken for. When the invoice is paid, the encumbrance reverses and the actual expenditure is recorded. Without this mechanism, a department could issue purchase orders that collectively blow past its budget and nobody would know until the bills came due.

Budget-to-actual comparison is the report GASB requires for the general fund and each major special revenue fund with a legally adopted annual budget. It shows the original budget, the final amended budget, and actual results side by side. Governments can present it as a basic financial statement or as required supplementary information.5Governmental Accounting Standards Board. Budgetary Comparison Schedules – Perspective Differences (GASB Statement No. 41)

Net Position and the Government-Wide Statements

GASB Statement No. 34 requires two government-wide financial statements prepared on the full accrual basis, presenting the government as a single economic entity rather than a collection of funds.3Governmental Accounting Standards Board. Summary – Statement No. 34

The Statement of Net Position lists total assets and deferred outflows of resources, then subtracts total liabilities and deferred inflows of resources. What’s left is net position, reported in three categories:

  • Net Investment in Capital Assets. The value of buildings, roads, and equipment, minus any outstanding debt used to acquire them. Typically the largest category, but not spendable cash.
  • Restricted. Resources subject to external constraints imposed by creditors, grantors, laws, or regulations. A bond covenant requiring reserves would fall here.
  • Unrestricted. Everything else. Theoretically usable for any purpose, though some may be internally committed by policy.

The Statement of Activities shows the net cost of each government function. It starts with expenses, subtracts program revenues like user fees and dedicated grants, and the remainder is what general revenues (mostly taxes) had to cover. The format reveals which services largely pay for themselves and which lean heavily on taxpayer support.

Annual Comprehensive Financial Report (ACFR)

The ACFR is the main output of a government’s accounting system. The name was updated from “Comprehensive Annual Financial Report” (CAFR) by GASB Statement No. 98, effective for fiscal years ending after December 15, 2021. The change was cosmetic, but the content requirements stayed the same.6Governmental Accounting Standards Board. GASB Statement No. 98, The Annual Comprehensive Financial Report The report has three sections:

  • Introductory Section. A transmittal letter from executive leadership, an organizational chart, and other context. Not audited.
  • Financial Section. The substantive core: the independent auditor’s report, management’s discussion and analysis (MD&A), the basic financial statements (government-wide and fund-level), notes to the financial statements, and required supplementary information such as budgetary comparisons.
  • Statistical Section. Multi-year trend data on financial performance, revenue capacity, debt capacity, demographics, and operating indicators.

Yellow Book and Single Audit

Government audits check more than whether the financial statements are fairly presented. They also evaluate compliance with laws, regulations, and grant requirements. The Yellow Book, formally the Government Accountability Office’s Government Auditing Standards (also called GAGAS), sets how these audits are conducted, covering financial audits, attestation engagements, and performance audits, with requirements for both individual auditors and audit organizations.7U.S. GAO. Yellow Book: Government Auditing Standards

A single audit is required for any state or local government (or other non-federal entity) that spends $1,000,000 or more in federal awards during its fiscal year. It examines the financial statements and whether the entity complied with the specific requirements attached to each federal program. The threshold and procedures come from the Office of Management and Budget’s Uniform Guidance.8eCFR. 2 CFR 200.501 – Audit Requirements

Where to Find the Reports These Terms Appear In

Most governments post their ACFR on their own website under a finance or transparency section. For governments that issue municipal bonds, the Electronic Municipal Market Access system (EMMA), operated by the Municipal Securities Rulemaking Board, is the SEC-designated repository for municipal securities data and continuing disclosure documents. EMMA is free to use and the most centralized source for bond-issuing governments across the country.9Municipal Securities Rulemaking Board. Electronic Municipal Market Access (EMMA) Start with the MD&A for a plain-language overview, then move to the government-wide statements for the long-term picture and the fund statements and budgetary comparisons for detail on whether the government is living within its means.
