FAR 19.1406 Sole-Source SDVOSB: A Plain-English Guide for 2026

For contracting officers under pressure to obligate funds before fiscal year end, FAR 19.1406 is one of the most powerful tools in the acquisition playbook. It permits a sole-source award directly to a Service-Disabled Veteran-Owned Small Business (SDVOSB), bypassing competitive procurement entirely — provided a handful of conditions are met. This guide walks through what the regulation actually says, when COs use it, and how to document the award without giving your IG heartburn.

What "sole-source" actually means

A sole-source contract is one awarded to a single vendor without competition. In the broader Federal Acquisition Regulation, sole-source awards are rare and require significant justification — typically a Justification and Approval (J&A) document defending why no competition was practicable. The socioeconomic set-aside programs (8(a), HUBZone, WOSB, and SDVOSB) carve out a streamlined exception: when specific dollar and qualification thresholds are met, the CO can issue a sole-source award without the full J&A process.

FAR 19.1406 is the SDVOSB-specific authority. It allows contracting officers to award contracts directly to qualifying SDVOSBs when:

• The anticipated award price (including options) does not exceed $8.5 million for manufacturing requirements, or $5 million for all other requirements (per the current text of FAR 19.1406 — verify thresholds at acquisition.gov before initiating an action);
• The contracting officer determines that two or more responsible SDVOSBs are not likely to compete for the requirement at a fair market price;
• The award can be made at a fair and reasonable price; and
• The SDVOSB has been verified by the SBA via VetCert.

Who qualifies as an SDVOSB

The SBA verifies SDVOSB status through its VetCert program. A qualifying firm must be at least 51% owned by one or more service-disabled veterans, must be controlled in its daily operations and long-term decisions by such veterans, and must meet the small-business size standard for the relevant NAICS code. Self-certification, which existed prior to 2024, is no longer sufficient for federal SDVOSB set-asides — the SBA-verified credential is the gating requirement.

Before initiating a sole-source action, the CO should confirm the vendor's VetCert status and active SAM.gov registration. Both are checkable in under five minutes using the vendor's UEI.

The "two responsible SDVOSBs" determination

The most common point of confusion — and the most common audit finding — is the "rule of two" determination. The CO must reasonably conclude that two or more responsible SDVOSBs would not likely submit offers at fair market prices. This is a market-research determination, not a guess.

What constitutes adequate market research varies by agency, but the typical record includes a documented review of SAM.gov, DSBS (Dynamic Small Business Search), VetCert, prior procurement history in the same NAICS, and where appropriate, a sources-sought or RFI posting. The determination should be in writing in the contract file and should explicitly state why two or more competing SDVOSBs were not anticipated.

Dollar thresholds in practice

The $8.5M / $5M thresholds are total contract value including options. A base year of $1.5M with four option years of $1M each ($5.5M total) sits within the $8.5M manufacturing ceiling but exceeds the $5M services ceiling — and would therefore not be available for sole-source under the services threshold.

Agencies that need to obligate above these thresholds via sole-source must use the broader sole-source authorities under FAR 6.302, which require a full J&A — a substantially more time-intensive process. For requirements that fit cleanly under 19.1406, the streamlined process can move from market research to award in as little as 4–6 weeks.

Documenting the award

While FAR 19.1406 doesn't require a full J&A, the contract file still needs a defensible record. At minimum:

• A market research memo documenting why two or more SDVOSBs were not anticipated to compete
• A determination of fair and reasonable price (often supported by an independent government cost estimate)
• Verification of the vendor's VetCert status and SAM registration on the award date
• A determination of contractor responsibility under FAR 9.104
• The standard contract documentation under the applicable FAR Part

When sole-source makes sense (and when it doesn't)

Sole-source SDVOSB awards work best when the requirement is narrow, the timeline is short, and one SDVOSB has clearly differentiated capability or relevant past performance. They work less well when the requirement is broad, the market is crowded with competing SDVOSBs, or the CO faces political sensitivity around competition.

The fiscal year-end use case is well known: agencies with unobligated funds and clearly scoped requirements use 19.1406 to award quickly and cleanly. But the authority is equally useful mid-year when an agency has identified a specific SDVOSB partner with the right capability stack.

Common pitfalls

Three failure modes account for most adverse audit findings on 19.1406 awards. First, weak market research — a CO who can't defend the "two responsible SDVOSBs" determination is exposed. Second, exceeded thresholds — including options pushes total value over the ceiling, which renders the award authority improper. Third, expired VetCert verification at the time of award — vendor status should be re-checked on the award date, not the date of initial market research.

The bottom line

FAR 19.1406 is one of the cleanest paths to award when an agency has a verified SDVOSB partner ready to perform a well-scoped requirement within the dollar ceilings. The procedural simplicity isn't a license to skip documentation — it's an invitation to do the documentation well. COs who treat the streamlined authority with the same discipline as a full J&A produce awards that survive scrutiny and deliver mission outcomes on the timeline that matters.
