8(a) Sole-Source Justification and Approval: FAR 19.808-1 Requirements and the $30 Million Threshold

When people search for an “8(a) sole source justification,” they are usually not looking for the same document CASRAI covers in Sole-Source Justification Letter. That page is about 2 CFR 200.320 — the noncompetitive-procurement justification a research institution writes when it buys a good or service from one vendor using federal award funds. This page is about a different, upstream document: the Justification and Approval (J&A) a federal agency itself must complete under FAR 19.808-1 before it can sole-source a contract to a firm certified under the Small Business Administration’s 8(a) Business Development Program above a set dollar ceiling. It is a federal-acquisition document, not a grant-recipient procurement document, and the two are easy to conflate because both are called a “sole-source justification” in casual use.

This guide covers the two distinct dollar thresholds that govern 8(a) sole-source awards, what FAR 19.808-1 itself requires, what the underlying J&A document must contain under FAR 6.303-2, and where a research institution actually intersects with this process. It does not cover the recipient-side procurement justification a university writes for its own noncompetitive purchases (see Sole-Source Justification Letter for that) or the separate, narrower sole-source authority for SBIR/STTR Phase III awards (see SBIR Phase III: Sole-Source Rights Most Institutions Never Use, which operates under 15 U.S.C. 638(r)(4) and requires no FAR 6.303 justification at all).

The 8(a) program in brief

The 8(a) Business Development Program is an SBA program that helps small businesses owned by socially and economically disadvantaged individuals compete for federal contracts, in part through set-aside and sole-source contracting authority not available to businesses outside the program. A firm must apply to and be certified into the program by SBA; certification is time-limited and must be current at the time of any 8(a) award. Federal agencies use the 8(a) program in two structurally different ways: a competitive 8(a) award, solicited among multiple eligible 8(a) firms, and a sole-source 8(a) award, negotiated directly with one 8(a) firm without competition. Which path applies is not the contracting officer’s free choice — it is determined by the dollar thresholds below.

Two different dollar thresholds, not one

Coverage of “the 8(a) sole-source threshold” often collapses two separate FAR provisions that do different jobs. Confusing them is the most common error in this area:

• FAR 19.805-1(a)(2) — the competitive-award threshold. Once the anticipated value of an 8(a) requirement exceeds $8.5 million for an acquisition assigned a manufacturing NAICS code, or $5.5 million for any other acquisition, the requirement generally must be competed among eligible 8(a) participants rather than awarded sole-source. Below these figures, a contracting officer may request a sole-source 8(a) award for a single firm without opening the requirement to other 8(a) competitors.
• FAR 19.808-1(a) — the sole-source ceiling. Independently of the competitive threshold above, SBA “may not accept for negotiation a sole-source 8(a) contract that exceeds $30 million” unless the requesting agency has first completed a justification meeting the requirements of FAR 6.303. In practice this ceiling matters most for the manufacturing/other-than-manufacturing acquisitions and bundled requirements that can otherwise stay below 19.805-1’s competitive trigger yet still reach a very large dollar value — the $30 million figure is the backstop that forces a documented, agency-level justification once a sole-source 8(a) award gets that large, rather than allowing indefinitely large noncompetitive awards under the 8(a) authority.

Dollar thresholds set in the FAR are periodically revised by rulemaking; treat the $30 million and $8.5/$5.5 million figures above as the currently codified text and confirm against the live FAR (acquisition.gov/far) or your institution’s contracts office before relying on a specific figure for a live procurement decision, rather than treating any single web page — including this one — as the system of record.

What FAR 19.808-1 itself requires

Beyond the $30 million justification trigger, 19.808-1 sets out the mechanics of an 8(a) sole-source award once a specific firm has been identified:

• SBA is responsible for initiating negotiations with the requesting agency within an agreed timeframe; if SBA does not do so and the agency cannot wait, the agency may, after notifying SBA, pursue the acquisition from other sources instead.
• SBA should participate in negotiating the contract terms whenever practicable, and may authorize the contracting officer to negotiate directly with the 8(a) firm — but whether or not direct negotiation happens, SBA must approve the resulting contract before award.
• The 8(a) firm must represent that it qualifies as small under the size standard tied to the NAICS code assigned to the contract, and it must be a current 8(a) program participant at the time of the sole-source award — a firm that has graduated or been terminated from the program is not eligible, even if it held 8(a) status when the relationship began.
• A special restriction applies to follow-on work: an 8(a) participant owned by an Alaska Native Corporation, Indian Tribe, Native Hawaiian Organization, or Community Development Corporation generally may not receive a sole-source follow-on award if the predecessor contract was performed by a different 8(a) participant owned by that same entity (13 CFR 124.109–124.111 sets out the detail).

What the Justification and Approval (J&A) must contain

FAR 19.808-1 does not restate its own content requirements — it incorporates them by reference from FAR 6.303, the same justification framework used for any noncompetitive federal contract award. A J&A prepared to clear the $30 million 8(a) sole-source threshold must include, per FAR 6.303-2:

1. Identification of the agency and contracting activity, with the document specifically labeled a justification for other than full and open competition.
2. A description of the nature and purpose of the action being approved.
3. A description of the supplies or services required, including the estimated dollar value.
4. Identification of the specific statutory authority permitting other than full and open competition (for an 8(a) sole-source award, this traces to the Small Business Act’s 8(a) authority, one of the categories FAR 6.302-5 recognizes as a statute expressly authorizing award to a specified source).
5. A demonstration that the 8(a) firm’s qualifications, or the nature of the requirement itself, justify use of that authority — the substantive core of the document, comparable to the “why only this source” narrative in a recipient-side sole-source letter, but written by the contracting officer about the 8(a) firm rather than by a PI about a vendor.
6. A description of the efforts made to solicit interest from other sources, and whether public notice of the requirement was provided.
7. A contracting officer determination that the anticipated cost to the government is fair and reasonable.
8. A description of the market research conducted, or, if none was conducted, the reason it was not.
9. Any other facts supporting use of other than full and open competition.
10. A listing of any sources that expressed written interest in the acquisition.
11. A statement of the actions the agency will take, if any, to remove barriers to competition before a future acquisition of the same requirement.
12. The contracting officer’s certification that the justification is accurate and complete to the best of their knowledge and belief.

Several of these elements — the market-research description, the price-reasonableness determination, the “why only this source” narrative — will look structurally familiar to anyone who has prepared the recipient-side sole-source justification letter under 2 CFR 200.320. The underlying logic is the same (competition is the default; a noncompetitive award has to earn its exception in writing), even though the regulatory authority, the preparer, and the dollar mechanics are entirely different.

Where a research institution actually intersects with this process

FAR 19.808-1’s J&A is prepared and signed by the requesting federal agency’s contracting officer, not by the institution receiving or benefiting from the award. A research institution or its affiliated entities intersect with this specific FAR provision in a narrower set of situations than the generic “sole source” search term suggests:

• The institution (or an affiliated organization) is itself 8(a)-certified. A small number of research entities — often tribally affiliated research corporations, or small businesses spun out of or partnered with a university — hold current 8(a) certification and are themselves the recipient of a sole-source award under this authority. In that position, understanding what the agency’s J&A must establish is useful for shaping the capability statements and technical narratives the firm supplies in support of the award, even though the firm does not draft the J&A itself.
• The institution holds a federal prime contract, not a grant. Where a university or research center is itself the prime contractor on a federally funded effort, its sponsored-programs or contracts office is the one negotiating against a FAR-based contract rather than Uniform Guidance award terms, and needs to recognize when a subcontract-level small-business obligation (governed by the institution’s own subcontracting plan under FAR 19.702 and 52.219-9, not by 19.808-1 directly) is distinct from an agency’s own 8(a) sole-source award to a third party.
• The institution’s procurement or supply-chain office tracks federal small-business set-aside policy generally — the same audience already served by CASRAI’s 2 CFR 200 Procurement Standards and simplified acquisition threshold guides, who need to distinguish FAR-side federal acquisition rules from the Uniform Guidance rules that actually govern their own grant-funded purchasing.

For most research administrators, the practical takeaway is diagnostic rather than procedural: recognizing that “8(a) sole source” and “our sole-source justification letter” are governed by different regulations, prepared by different people, and triggered by different dollar figures, so the right guide — and the right office — gets consulted for the actual document in front of them.

How this differs from other sole-source and set-aside authorities

FAR 6.302-5 recognizes 8(a) sole-source authority (15 U.S.C. 637) alongside several other statutes that let an agency award to a specified source without competition, including HUBZone (15 U.S.C. 657a) and Women-Owned Small Business set-asides (15 U.S.C. 637(m)). Each program has its own eligibility rules and its own dollar mechanics; a HUBZone or WOSB sole-source award is not governed by FAR 19.808-1’s $30 million figure, which is specific to the 8(a) program. Separately, an SBIR/STTR Phase III sole-source award — covered in CASRAI’s SBIR Phase III sole-source guide — sits entirely outside FAR 6.302-5 and 19.808-1: it is authorized directly by 15 U.S.C. 638(r)(4), has no dollar ceiling, and requires no FAR 6.303 justification at all, only a citation that the work derives from the underlying SBIR/STTR effort. Readers comparing sole-source mechanisms side by side may also find CASRAI’s Sole Source vs. Single Source comparison and Federal Contracts vs. Grants for University Research guide useful for the broader contract-versus-grant framing this page assumes.

Frequently asked questions

Is an 8(a) sole-source award the same as an 8(a) set-aside?

No. A set-aside restricts competition to 8(a)-eligible firms but still requires competition among them. A sole-source award goes to one specific 8(a) firm without competing the requirement at all. FAR 19.805-1’s competitive threshold ($8.5 million for manufacturing NAICS codes, $5.5 million for other acquisitions) is the dividing line between the two paths for a given requirement.

Who actually writes the 8(a) sole-source J&A — the agency or the 8(a) firm?

The requesting federal agency’s contracting officer prepares and certifies the J&A under FAR 6.303. The 8(a) firm supplies supporting information (capability, pricing, market position) but does not author or sign the justification document itself.

What happens below the $30 million threshold?

FAR 19.808-1’s specific $30 million justification trigger does not apply; SBA’s acceptance and the standard 8(a) sole-source negotiation process (still subject to the separate 19.805-1 competitive threshold and the firm’s current 8(a) eligibility) governs instead, without a full FAR 6.303-style J&A being required by this section.

Does this replace 2 CFR 200.320 for a university’s own procurement?

No. 2 CFR 200.320 governs how a federal award recipient buys goods or services with award funds and is a completely separate regulatory track from FAR 19.808-1, which governs how a federal agency itself awards a contract. An institution can be subject to both in different roles — as an award recipient buying supplies, and separately as a prime contractor or 8(a)-certified awardee under a FAR-governed contract — but the two documents are not interchangeable and one does not satisfy the other.

Are the dollar thresholds in this guide likely to change?

FAR dollar thresholds are adjusted by rulemaking from time to time, and acquisition-community discussion of raising the 8(a) sole-source ceiling recurs periodically. The figures on this page reflect the FAR text as currently published at acquisition.gov; confirm the current figure directly against the live FAR text or your contracting office before relying on a specific number for an active procurement.

This page is a general reference on FAR 19.808-1 and the 8(a) sole-source Justification and Approval process, not legal advice. It does not cover subcontract-level small-business set-aside obligations under an institution’s own subcontracting plan, which are governed by separate FAR provisions. An institution’s contracts or sponsored-programs office, and the cognizant federal contracting officer or SBA district office, are the authoritative source for a specific award.
