Subcontractor

A subcontractor is a business that performs work under a federal contract by entering into an agreement with the prime contractor rather than directly with the government agency. The government has no privity of contract with subcontractors, meaning all direction, payment, and accountability flow through the prime.

What is a Subcontractor?

Subcontractors are an essential part of the federal contracting ecosystem. Prime contractors use them to add specialized capabilities, expand capacity, satisfy small business subcontracting goals, and compete for contracts that require skills they do not possess in-house.

Federal regulations (FAR Part 44) require prime contractors to obtain contracting officer approval before adding subcontractors above certain dollar thresholds, and to flow down applicable FAR clauses, including labor standards, cybersecurity requirements, and small business reporting obligations, to their subcontractors.

Primes must report subcontract awards above $30,000 in the Electronic Subcontracting Reporting System (eSRS) when the prime contract includes a subcontracting plan. This data is publicly visible through USAspending subaward records, which list the subcontractor's name, UEI, amount, and business type. Savvy contractors mine this data to map which primes are actively subcontracting in their target market.

For small businesses, subcontracting is often the fastest entry point into the federal market. It provides a first government contract reference, exposes teams to federal compliance requirements, and builds relationships with primes who may include the company in future proposals. The key limitation is that subcontract past performance is harder to cite independently on future proposal submissions than prime contract experience.

Why Subcontractor status matters for government contractors

Subcontracting lets companies enter federal markets without winning a prime award outright. Small, emerging, or niche businesses can build credibility, earn revenue, and develop past performance references while working under an experienced prime. A track record as a reliable subcontractor frequently leads to teaming agreement invitations and eventually prime opportunities. Read more in our subcontracting guide for small businesses.

Example

A two-year-old cybersecurity startup lacks the past performance to win a $10M Department of Defense prime contract on its own. It partners with an established IT services prime, agreeing to provide penetration testing as a subcontractor for 15% of the contract value. After two years, the startup can reference the engagement as relevant experience when competing for its own prime awards.

Frequently Asked Questions

Does subcontracting past performance help when bidding for a prime contract?

Yes, but it is weighted differently than prime experience. Proposals should clearly explain the subcontractor's specific role, dollar value, and deliverables, evaluators want to see work analogous to what the prime scope requires, not just a name on a team chart.

Are subcontractors subject to federal contracting regulations?

Subcontractors must comply with FAR clauses that the prime flows down, which can include cybersecurity standards (CMMC, NIST 800-171), labor law requirements, and small business reporting. The specific obligations depend on the prime contract type and value.

How can I find subcontracting opportunities?

Prime contractors post subcontracting opportunities on their websites, through SUB-Net on SBA.gov, and at industry events. USAspending subaward data reveals which primes actively subcontract in your NAICS codes and at what dollar levels, helping you target outreach.

What is a subcontracting plan?

When a prime contract with a large business exceeds $750,000 (or $1.5M for construction), FAR 19.7 requires the prime to submit a subcontracting plan committing to specific dollar and percentage goals for spending with small, small disadvantaged, women-owned, HUBZone, veteran-owned, and service-disabled veteran-owned businesses.
