# How appropriations and budgets actually flow
A community health nonprofit in Ohio has $180,000 sitting in a federal grant account on September 15. By September 30, if that money is not obligated (legally committed through a signed contract or purchase order), it disappears. Not carried forward. Not banked for next year. Gone, back to the U.S. Treasury.
The staff scramble to buy laptops and prepay a training contract. This is the famous "September spending rush," and it is not waste for its own sake. It is a rational response to how money moves through the public sector.
Let's follow one dollar from Congress to that Ohio program line, and you will see why every spending decision in this world is constrained before anyone even opens a checkbook.
An appropriation is a law that gives a federal agency legal authority to spend a specific amount of money for a specific purpose. No appropriation, no spending. Full stop.
Two things happen in the budget process, and people confuse them constantly:
A program can be authorized but not appropriated, meaning it legally exists but has no money. This happens all the time.
Appropriations bills pass through the House and Senate Appropriations Committees, which divide federal spending into 12 subcommittee bills (defense, labor-health, agriculture, and so on). When Congress cannot pass these on time, it uses a
For the official view of this machinery, the Congressional Research Service maintains a clear Introduction to the Federal Budget Process.
Here is a concept that trips up newcomers: appropriated money has a "color." That means each pot of money is legally restricted to a purpose and a time window.
Congress attaches three limits to almost every appropriation:
Violating any of these can breach the Antideficiency Act, a federal law prohibiting agencies from spending more than Congress provided or spending before funds are available. Violations must be reported to Congress and the President. Career officials take this very seriously.
The "time" limit is where "use it or lose it" comes from. Most operating funds are one-year money: available to obligate only during a single fiscal year.
The federal fiscal year (FY) runs October 1 to September 30. So FY2026 money became available October 1, 2025, and generally must be obligated by September 30, 2026.
Once the appropriation is law, money does not just gush out. The Office of Management and Budget (OMB) apportions it, releasing funds to agencies in controlled increments (often quarterly) so nobody spends the whole year's budget in month one.
The agency then allots money down to its divisions and programs. Only after this internal cascade does a program office have spending authority.
For a grant program, the agency now runs a competition or a formula distribution and makes an award to recipients: states, cities, universities, or nonprofits.

Now the money reaches our Ohio health nonprofit. And a new set of rules kicks in.
Federal grants to nonprofits are governed by the Uniform Guidance, the government-wide rulebook for federal awards (found in Title 2 of the Code of Federal Regulations). It sets standards for allowable costs, procurement, and reporting. If you work with federal money, you will hear "2 CFR 200" constantly. The full text is public at eCFR Title 2, Part 200.
Two constraints now shape every decision.
A restricted fund is money that can only be spent on the specific purpose the funder designated. A grant for maternal health screenings cannot buy office furniture for the finance team, even if the finance team is drowning.
Nonprofits track this using fund accounting, a system that segregates money into separate "funds" by restriction rather than pooling it. Instead of one bank balance, the organization effectively runs many small ledgers, each with its own rules.
This is why a nonprofit can look "cash rich" on paper and still be unable to pay a heating bill. The cash exists, but it is restricted to program purposes and legally cannot be touched for overhead.
Every grant has a period of performance: the window during which costs are allowable. Spend a dollar one day before the start date or one day after the end date, and it is unallowable. The funder will not reimburse it, and an auditor will flag it.
Because federal grants are usually cost reimbursement (the nonprofit spends first, then submits documentation to get repaid), timing errors hit cash flow directly. You laid out the money and now cannot recover it.
Put the pieces together and the "use it or lose it" behavior becomes logical.
Our nonprofit received one-year grant money tied to FY2026. By late September, the period of performance is closing. Any funds not obligated (committed through a signed agreement) revert to the funder and ultimately to the Treasury.
From the nonprofit's seat, unspent money is not a virtue. It signals the organization overestimated need, which can shrink next year's award. Funders often base renewal amounts partly on prior utilization. Leaving money on the table can quietly punish you.
So the staff prepay allowable contracts, buy needed equipment, and lock in training before the deadline. Done carelessly, this is waste. Done well, it is legitimate acceleration of real, budgeted needs.
The deeper fix, better multi-year budgeting and more no-year or multi-year appropriations, sits with Congress, not the grantee. Some programs do receive multi-year money precisely to reduce this distortion.

There is one more constraint that quietly strangles nonprofits: overhead.
Grants pay for direct costs (staff time on the program, program supplies) readily. But indirect costs, the shared expenses like rent, IT, accounting, and leadership that keep the whole organization running, are harder to recover.
Under the Uniform Guidance, a nonprofit can negotiate an indirect cost rate with the federal government, or use the de minimis rate. As of recent updates to 2 CFR 200, that default de minimis rate is 15 percent of modified total direct costs, raised from the older 10 percent figure. Confirm the current rate for any specific award, since these thresholds change.
Why this matters: if a grant only reimburses overhead at a low rate, every dollar of restricted program money can actually *cost* the nonprofit money to administer. Growth in grants can worsen the deficit. This is the counterintuitive "nonprofit starvation cycle," where organizations underinvest in their own infrastructure because funders will not pay for it.
For anyone entering this sector, three habits will make you fluent fast:
1. Always ask about the color of money. What fund is this? What is its purpose, period, and restriction? The answer changes what is possible.
2. Separate cash from availability. A large balance may be entirely restricted. Liquidity is not the same as spendability here.
3. Watch the calendar. Fiscal year ends and periods of performance drive behavior more than almost anything else.
Once you internalize that money arrives pre-constrained by law, the public sector's odd rhythms (the September rush, the CRCRThe percentage of visitors or prospects who complete a desired action (purchase, sign-up, contact form), calculated as conversions divided by total opportunities.View full definition → paralysis, the cash-rich-but-broke nonprofit) stop looking irrational and start looking like exactly what the rules require.
