# Fund accounting: why governments track money in silos
A city treasurer stares at a spreadsheet showing $40 million in the bank. Payroll is due Friday, and the general fund is $2 million short. Meanwhile, the water utility fund holds $15 million and the federal grant fund holds $10 million. The treasurer cannot touch a dollar of it. Not because of a lock on the account, but because of a rule that governs almost every government and nonprofit in the world: fund accounting.
If you come from the corporate world, this feels absurd. In a company, cash is cash. In the public sector, cash has a purpose stamped on it, and moving it across that boundary can be a legal violation.
This lesson explains why.
Fund accounting is a system that separates money into distinct pools ("funds"), each with its own balance sheet, its own revenues, and its own rules about how the money can be spent.
Think of it less like one big checking account and more like a house with dozens of labeled envelopes. The "road repair" envelope cannot pay the "library salaries" envelope, even if the road envelope is stuffed and the library envelope is empty.
The core reason is accountability. A company exists to generate profit for owners, so its accounting answers one question: are we making money? A government exists to deliver services with money the public entrusted to it, often for specific purposes. Its accounting answers a different question: did we spend each dollar on what we said we would?
This is called stewardship, and it is the organizing principle of public finance.
Governments in the United States follow standards set by the Governmental Accounting Standards Board (GASB), the body that writes the rulebook. Funds fall into three broad categories.
These pay for core public services financed mostly by taxes.
These operate like a business, charging fees for services.
Money the government holds on behalf of others and does not own. Pension trust funds are the classic example. This money can never be spent on government operations.
Now the treasurer's problem makes sense.
So even with $40 million in the bank, only the general fund's cash can legally cover payroll. "The budget" can look balanced in total while a single fund runs dry. This is why public finance professionals never look at a single bottom line. They look fund by fund.
The heart of fund accounting is one word: restriction.
This matters enormously in nonprofits too. A donor who gives $1 million "for scholarships" has created a restricted fund. The nonprofit cannot use that gift to make rent, even if it is about to be evicted. Nonprofits report these under FASB standards as net assets with donor restrictions versus without donor restrictions. Different rulebook, same logic.
A fair question. Pooling would be more efficient. Fund accounting exists precisely to prevent that efficiency, because the risk it guards against is worse than inefficiency: the temptation to raid dedicated money.
Imagine a city facing a deficit. Without restrictions, it could quietly drain the pension fund, or spend next year's bond repayment money, or divert road taxes to close the gap. Voters approved those taxes and bonds on a promise. Fund accounting turns that promise into an accounting wall.
There is a legal escape valve, but it is deliberately narrow. Governments can make an interfund transfer, moving money between funds, but only when the law or the budget authorizes it. A common legal move is an interfund loan, where one fund lends cash to another with a documented repayment plan. These are disclosed, tracked, and audited. They are not a way to make restrictions disappear.
Government financial reports, published annually as the Annual Comprehensive Financial Report (ACFR), present information in two layers.
1. Fund-level statements: the detailed, silo-by-silo view. This is where you see each fund's health.
2. Government-wide statements: a consolidated, big-picture view that looks more like corporate accounting, added by GASB to help outside readers see the total.
A skilled analyst reads both. The government-wide view tells you overall financial position. The fund view tells you whether the money that matters is actually available where it is needed. A city can be solvent overall and still unable to make payroll from the right fund.

When you evaluate a government or nonprofit, ask these questions fund by fund:
This is the difference between someone who reads "$40 million in the bank" and someone who asks "$40 million in which funds, and with what strings attached?"
