Contractors do not need to be budget experts, but a working knowledge of how federal money is controlled explains a great deal: why a contract is incrementally funded, why a contracting officer cannot simply add money, why “subject to availability of funds” appears in so many documents and why September is so busy. Three principles do most of the work. Appropriations law scholars summarize them as purpose, time and amount.
Purpose
An appropriation may be used only for the purposes Congress specified. An agency’s operating funds cannot be used for construction if Congress appropriated construction money separately; research funds cannot pay for routine maintenance. Within a purpose, agencies have discretion to decide what is necessary to carry it out, which is why the same account can fund office supplies and consulting services. For contractors, the practical effect is that a requirement must fit the account that pays for it, and a program office cannot always move money from one pot to another to fund something it wants.
Time
Each appropriation is available for obligation during a defined period: one year for most operating funds, several years for many procurement and research accounts, and indefinitely for no-year funds. An obligation, such as signing a contract, must be made within that window. The bona fide needs rule adds that the obligation must meet a need arising within the same period. Together, these rules shape how contracts are structured. A multiyear services contract is usually funded one option year at a time, with each year’s funds obligated when that year’s appropriation becomes available.
Amount
The Antideficiency Act forbids federal officials from obligating or spending more than Congress has appropriated, or from obligating money before it is appropriated. Violations are serious, with reporting to Congress and potential penalties for the individuals involved. This is why contracting officers are careful about funding. They cannot award a contract, exercise an option or approve a modification unless the money is actually available, and they cannot let a contractor incur costs the government has not committed to pay.
How these rules show up in your contract
- Subject to availability of funds. A clause used when a solicitation is issued or an award made before the appropriation is enacted. The government’s obligation does not exist until funds are available, and the contractor should not begin work until notified.
- Incremental funding. Cost-reimbursement and some other contracts are funded in increments. The limitation of funds clause requires the contractor to notify the government as costs approach the amount obligated and makes clear the government is not obligated beyond it.
- Option exercise timing. Options are typically exercised near the start of a new fiscal year or when funds are certified, and a delay often reflects funding, not dissatisfaction.
- Continuing resolutions. When Congress funds the government temporarily, agencies may be limited to the prior year’s rate of spending and barred from starting new programs, slowing awards.
What contractors should and should not do
Never begin work, expand scope or exceed funded amounts on the strength of a verbal assurance. If a government employee asks you to proceed before funding is in place, the request itself may be improper, and the risk of nonpayment falls on you. Watch funded amounts on incrementally funded contracts and send the notices your clauses require. When funding questions arise, ask the contracting officer in writing. Program staff may want to help, but only the contracting officer can commit the government’s money.
Understanding purpose, time and amount turns frustrating moments into explicable ones. The option exercised late, the modification that had to wait, the award that landed on September 29: each is usually appropriations law doing what it was designed to do. Contractors who grasp that work with the system rather than against it, and they avoid the one outcome that cannot be fixed afterward: performing work the government never had authority to buy.
