FAR 17.105-1—Uses.
Plain-English Summary
FAR 17.105-1 explains when the multi-year contracting method may be used and what findings must support that decision. It covers two different approval standards: one for civilian agencies generally, and a more specific standard for DoD, NASA, and the Coast Guard when buying supplies. It also states that multi-year contracting may be used for supplies or services, and it addresses the funding risk that if later-year appropriations are not made, the agency must cancel the contract. In practice, this section is about balancing competition, economy, and program stability against the risk of committing to future requirements before all funds are available. Contracting officers and program officials use it to justify whether a multi-year approach is appropriate, while contractors need to understand that these contracts can be canceled if future funding does not materialize.
Key Rules
Civilian agency findings
For agencies other than DoD, NASA, and the Coast Guard, the contracting officer may use a multi-year contract only if the head of the contracting activity determines that the need is reasonably firm and continuing over the contract period and that the multi-year approach is in the best interests of the United States. The best-interest finding must be tied to either improved competition or better economy in administration, performance, or operations.
DoD, NASA, and Coast Guard standard
For DoD, NASA, and the Coast Guard, the head of the agency may use a multi-year contract for supplies only when all five listed conditions are met. These conditions focus on savings, stable demand, stable design and manageable technical risk, a reasonable expectation of future funding requests, and realistic cost and savings estimates.
Savings must be meaningful
Under the DoD, NASA, and Coast Guard standard, the multi-year method must produce significant savings compared with annual contracting. The savings analysis must be based on the total estimated cost of carrying out the program through annual contracts, not just a narrow price comparison.
Requirements must be stable
The minimum need to be purchased must be expected to remain substantially unchanged over the contract period in terms of production rate, procurement rate, and total quantities. This requirement is intended to prevent use of a multi-year contract when demand is too uncertain or likely to fluctuate materially.
Design and technical risk must be controlled
The supplies must have a stable design, and the technical risks cannot be excessive. This means the agency should not use a multi-year approach when the item is still evolving or when performance, manufacturing, or integration risks could undermine the expected benefits.
Funding expectation and cancellation risk
The agency must have a reasonable expectation that it will request funding at a level sufficient to avoid cancellation throughout the contemplated period. If funds are not appropriated to support the succeeding years’ requirements, the agency must cancel the contract, so the funding outlook is a central part of the decision.
Applies to supplies and services
The multi-year contracting method may be used for the acquisition of both supplies and services. However, the specific findings in paragraph (b) are written for supplies, so agencies must still ensure the applicable approval and justification framework fits the type of acquisition.
Responsibilities
Contracting Officer
Determine whether the acquisition is suitable for multi-year contracting, document the basis for the approach, and ensure the required approval and findings are obtained before award. The contracting officer must also recognize the cancellation risk if future appropriations are not available.
Head of the Contracting Activity
For civilian agencies covered by paragraph (a), make the required determination that the need is reasonably firm and continuing and that the multi-year contract is in the best interests of the United States.
Head of the Agency
For DoD, NASA, and the Coast Guard under paragraph (b), approve use of a multi-year contract for supplies only when all five statutory-style conditions are satisfied, including savings, stability, technical risk, funding expectation, and realistic estimates.
Program/Requirement Officials
Provide the demand, technical, and cost data needed to show that the requirement is stable, the design is mature, the savings are real, and the funding outlook supports the planned contract period.
Budget/Funding Officials
Assess whether future-year funding is reasonably expected and whether the agency can support the contract without creating an unacceptable cancellation risk.
Contractor
Understand that performance may extend across multiple years but remains subject to the government’s funding and cancellation rules, and price or plan proposals accordingly.
Practical Implications
Multi-year contracting is not just a longer contract term; it requires a specific justification showing stability, savings, and funding confidence. Agencies that cannot support those findings should use annual contracting instead.
The biggest pitfall is overestimating future demand or underestimating technical risk. If quantities, production rates, or design are likely to change, the multi-year approach may fail to deliver the expected savings.
Funding uncertainty matters throughout the contract period. Even if the contract is awarded, later-year appropriations can force cancellation, so both agencies and contractors need to plan for that possibility.
For civilian agencies, the key question is whether the multi-year approach is in the government’s best interest through competition or administrative economy. For DoD, NASA, and the Coast Guard, the analysis is more demanding and savings-driven for supplies.
Contractors should pay close attention to cancellation language, pricing assumptions, and any schedule or production commitments that depend on future-year funding.
Official Regulatory Text
(a) Except for DoD, NASA, and the Coast Guard, the contracting officer may enter into a multi-year contract if the head of the contracting activity determines that- (1) The need for the supplies or services is reasonably firm and continuing over the period of the contract; and (2) A multi-year contract will serve the best interests of the United States by encouraging full and open competition or promoting economy in administration, performance, and operation of the agency’s programs. (b) For DoD, NASA, and the Coast Guard, the head of the agency may enter into a multi-year contract for supplies if- (1) The use of such a contract will result in significant savings of the total estimated costs of carrying out the program through annual contracts; (2) The minimum need to be purchased is expected to remain substantially unchanged during the contemplated contract period in terms of production rate, procurement rate, and total quantities; (3) There is a stable design for the supplies to be acquired, and the technical risks associated with such supplies are not excessive; (4) There is a reasonable expectation that, throughout the contemplated contract period, the head of the agency will request funding for the contract at a level to avoid contract cancellation; and (5) The estimates of both the cost of the contract and the cost avoidance through the use of a multi-year contract are realistic. (c) The multi-year contracting method may be used for the acquisition of supplies or services. (d) If funds are not appropriated to support the succeeding years’ requirements, the agency must cancel the contract.
