FAR 17.202 authorizes a contracting officer to include options in a federal contract, whether awarded through sealed bidding or negotiation, when doing so is in the government’s interest. That single sentence sets the frame for the whole rule: options are permitted, not required, and their inclusion has to be justified by real benefit to the government rather than convenience or habit. The rest of FAR 17.202 works out what that standard means in practice and lists the situations where an option must not be used at all.1Acquisition.GOV. 48 CFR 17.202 – Use of Options
An option itself is a unilateral right the contract gives the government: the ability to buy additional supplies or services, or extend the term, on terms fixed at award. The contractor cannot refuse if the government exercises the option, and the government is never obligated to exercise it.2Acquisition.GOV. 48 CFR 2.101 – Definitions
When Including an Option Serves the Government’s Interest
The government’s-interest test usually comes down to economy and efficiency. An option avoids running a fresh competition every time an agency needs more of the same thing, and it lets the agency lock in pricing while it works through uncertainty about future quantities, funding, or workload. It also fits situations where continuity matters: service contracts where a switch would disrupt operations, or supply contracts where the contractor has meaningful startup costs that would be wasted if the relationship ended at the base period.
None of that is automatic. The contracting officer has to identify a real reason the option benefits the government before including it in the solicitation. FAR 17.205 requires that reason, along with the quantities or term covered, the notification period, and any price limitations, to be justified in writing and placed in the contract file.3Acquisition.GOV. 48 CFR 17.205 – Documentation
When FAR 17.202 Prohibits an Option
FAR 17.202(c) sets three hard limits. A contracting officer cannot include an option when any of them applies.1Acquisition.GOV. 48 CFR 17.202 – Use of Options
The first is contractor risk. If the price or availability of the materials or labor needed for the option period cannot reasonably be foreseen, an option would force the contractor to commit to a price it has no way of standing behind. That is not a fair bargain and the FAR treats it as off-limits.
The second is market volatility. Options assume the underlying price of the work will stay in a predictable range. When the market is unstable, the option price will either sit too high because the contractor built in a risk premium, or too low and expose the contractor to losses on performance. Either result defeats the purpose of the option.
The third is the anti-circumvention rule. If the government already knows it needs the additional quantities and already has the money for them, that work is a current requirement and belongs in the base contract, competed up front. Burying known requirements in option quantities to make the base competition look smaller is not allowed. There is one narrow exception: when the base quantity is a learning or testing quantity and competing follow-on quantities separately would be impracticable once the initial award is made.
The Extra Step for Sealed Bidding
Sealed bidding carries one additional requirement under FAR 17.202. Before issuing the solicitation, the contracting officer must make a written determination that there is a reasonable likelihood the option will actually be exercised.1Acquisition.GOV. 48 CFR 17.202 – Use of Options The purpose is to keep speculative option quantities out of sealed-bid solicitations, where they would distort bid prices and skew the competition. Negotiated procurements do not carry this same pre-solicitation determination, though the general government’s-interest standard still applies.
What Has to Go Into the Contract File
FAR 17.205 turns the use decision into a paper record. The contracting officer justifies, in writing, the quantities or term the option covers, the notification period for exercising it, and any price limitations. That justification lives in the contract file. If the acquisition also needs justifications and approvals under the competition rules of FAR Part 6, those documents have to address both the base requirement and the increase the option would allow.3Acquisition.GOV. 48 CFR 17.205 – Documentation
Two things follow from this. The option has to be a deliberate planning choice rather than a late add. And the file has to be complete enough that someone reviewing it later can see why the option was included, what it covers, and how it fits the competition framework.
How Pricing and Evaluation Support the Use Decision
The FAR treats the option price as something that must be settled at award, not at exercise. FAR 17.207(f) recognizes a specific dollar amount, a formula or provision in the base contract that produces a calculable price, a cost-type structure with a fixed or maximum fee (or a fee calculable by formula), an economic price adjustment tied to defined indices, or a price tied to prevailing labor rates published by the Secretary of Labor.4Acquisition.GOV. 48 CFR 17.207 – Exercise of Options What is not allowed is renegotiating a fixed price under the guise of exercising an option.
Evaluation follows the same logic. When the government determines before issuing the solicitation that the option is likely to be exercised, the offers for the option quantities or periods must be evaluated as part of source selection, and the solicitation must state clearly whether the evaluation basis includes or excludes the option. Evaluating the option is what preserves the competitive foundation for later exercising it. A higher-level determination can skip the evaluation when it would not serve the government’s best interests, for example where funds almost certainly will not be available, but skipping creates real complications at exercise because the Part 6 competition question reopens.5Acquisition.GOV. 48 CFR 17.206 – Evaluation
Pricing analysis at award also has to watch for imbalance. FAR 15.404-1(g) identifies the base quantity versus option quantity split as one of the highest-risk scenarios for unbalanced pricing, where an offeror wins with a low base price and loads profit into the option periods it expects the government to exercise. The contracting officer can reject an offer outright if the imbalance poses an unacceptable risk to the government.6Acquisition.GOV. 48 CFR 15.404-1 – Proposal Analysis Techniques
What Must Be True Before an Option Can Be Exercised
Even a properly included option cannot be exercised on autopilot. FAR 17.207 requires the contracting officer to determine, before exercising, that funds are available; that the requirement covered by the option still exists; that exercise is the most advantageous method of meeting the need, considering price and other factors; and that the contractor’s performance has been acceptable.4Acquisition.GOV. 48 CFR 17.207 – Exercise of Options The “most advantageous method” finding is usually supported by an informal look at current market prices or by asking whether a new solicitation would likely produce a better deal. A full new competition is not required and is discouraged when the option price already looks like the better outcome.
The contractor also has to be eligible. Under FAR 9.405-1, an agency generally cannot exercise an option on a contract held by a debarred or suspended contractor unless the agency head makes a written finding of compelling reasons.7Acquisition.GOV. 48 CFR 9.405-1 – Continuation of Current Contracts
Before signing off, the contracting officer prepares a written determination for the file confirming that the exercise complies with the option terms, with FAR 17.207, and with the competition requirements of FAR Part 6. The Part 6 requirement for full and open competition is treated as satisfied when the option was evaluated during the initial competition and the exercise price is specified in or determinable from the base contract. If the option was not evaluated, exercising it may require a separate justification for other-than-full-and-open competition.4Acquisition.GOV. 48 CFR 17.207 – Exercise of Options Written notice goes to the contractor within the time the contract specifies, and the option is exercised through a contract modification citing the option clause as its authority.
One Boundary Worth Naming: FAR 52.217-8
FAR 52.217-8 is easy to confuse with a standard option under FAR 17.202, and it is not the same thing. That clause lets the government require continued performance of services for up to six months total beyond the contract’s end, at the contract rates adjusted only for changes in prevailing labor rates published by the Secretary of Labor.8Acquisition.GOV. 48 CFR 52.217-8 – Option to Extend Services It is a bridge while a follow-on contract is being awarded, not a planning tool for continuing needs, and the FAR 17.202 use decision is aimed at the latter.
