When the federal government signs a big contract, a slice of the work is set aside. The winning firm must plan to pass some tasks to small businesses. The plan is not a favor. It is federal policy written into the contract itself.
The rules live in Part 19 of the Federal Acquisition Regulation. That rulebook governs how the government buys. It turns each major contract into a mix of prime work and required small business roles. This connects to our earlier piece, The Prompt Payment Act: When Government Must Pay Its Bills.
Why the Duty Exists
The policy rests on statute. Under FAR 19.702, any large contractor must agree to a fair share. It must give small firms the maximum practicable chance to take part in the work. The duty flows from section 8(d) of the Small Business Act, according to the regulation text.
The frame is the Federal Acquisition Regulation, or FAR. As one encyclopedia entry explains, the FAR is the main set of rules for federal buying. The text describes how executive branch agencies acquire products and services. Much of the modern text dates to 1984. Part 19 carries the small business programs.
When a Plan Is Required
The trigger is dollar-based. In negotiated buys, the line sits at $900,000, according to FAR 19.702. For construction, it sits at $2 million. A solicitation above the line must demand an acceptable plan from the leading offeror.
A firm that fails to negotiate an acceptable plan becomes ineligible for award. The rule reaches sealed bidding too. There, the winning bidder must hand in a plan within the time the contracting officer sets. Missing that window also means losing the award. The same duty can arrive midstream. A contract change that pushes the value over the line can trigger a plan. The catch: the contracting officer must find real subcontracting possibilities.
What Goes Into a Plan
A plan is a detailed document, not a promise. Under FAR 19.704, it must set separate percentage goals for several groups of small firms. The listed groups are:
- Small business concerns
- Veteran-owned small business
- Service-disabled veteran-owned small business
- HUBZone small business
- Small disadvantaged business
- Women-owned small business
The plan must also cover the ground game. It names the types of supplies and services to be farmed out. It explains how the goals were set. It describes how the firm will find suppliers to solicit. It names the employee who will run the program. And it lists the records the firm will keep to show compliance, from source lists on down. For individual plans, there is one more option. The contracting officer may set goals against total contract dollars, not just subcontract dollars.
Formats can differ. A master plan covers a whole company. An individual plan binds one contract. A commercial plan serves firms that sell commercial products and services. Once a commercial plan is approved, the rule shields it. The government may not demand another while it stays in effect.
Payment Duties and Real Teeth
The regulation also watches cash flow. Primes must set procedures to pay small business subcontractors on time, according to FAR 19.702. The duty covers every listed group, from veteran-owned to women-owned firms. The rules call a payment untimely if it sits more than 90 days past due.

Enforcement runs through performance, not just paperwork. Falling short feeds a prime's past performance record. Agencies weigh that record in future buys. A prime that shrugs off its goals risks its ratings. That, in turn, risks its claim on the next big award.
Conclusion
Subcontracting plans put small business policy into the fine print of federal buying. The percentages are negotiated, but the duty is not optional. For large contractors, hitting the goals is part of the job. For small firms, each plan is a standing invitation. It opens supply chains they could rarely crack alone.
