An option year is a contractual provision that gives the government the unilateral right to extend a contract beyond its base period at pre-negotiated pricing. The most common federal services structure is a one-year base period plus four one-year options (often written "1+4"), producing a five-year total potential ordering period. Option pricing is established at award — the contractor cannot renegotiate option-year rates absent a bilateral modification — and is exercised by the contracting officer through a unilateral modification before the prior period expires. FAR Subpart 17.2 governs the rules: options must be evaluated for price reasonableness at award, exercised within the option exercise window, and must not be used to circumvent competition requirements.
The government has no obligation to exercise an option. The decision typically rests on continued need, available funding, and contractor performance — the most common reasons options go unexercised are program cancellation, congressional appropriation cuts, and CPARS-documented performance issues. Some contracts include 52.217-8 short-form extensions allowing the CO to extend up to six months at the prior period's rates if the option was missed or the recompete is delayed. Bilateral price renegotiation can occur at option exercise but requires contractor agreement; most COs decline to reopen pricing once awarded.
For small contractors, option-year pricing strategy directly affects long-term profitability. Loading too much escalation creates apparent unaffordability that can drive non-exercise. Loading too little leaves margin on the table as wages inflate. Disciplined escalation aligned to BLS labor cost projections is the conservative posture.
