Small Business Subcontracting Plans: What Happens When You Get Big

Growing past small business size standards isn’t just a milestone — it triggers a compliance obligation most new small business contractors have never had to think about: the subcontracting plan. If you’re the prime on a large contract and you no longer qualify as small, federal law requires you to document how you’ll direct work to small businesses, not just continue being one yourself.

When a Subcontracting Plan Is Required

Subcontracting plans are generally required for any contract or subcontract expected to exceed $750,000 ($1.5 million for construction) under FAR 19.702 — a different, higher threshold than the simplified acquisition threshold, and a common point of confusion — where the prime is a large business (or a small business that has grown past the relevant size standard) and the contract has subcontracting possibilities. Small businesses performing as the prime on their own contracts are generally exempt — the obligation activates specifically when you cross from small to “other than small” status, or when a large business is the prime from the start.

What a Subcontracting Plan Must Include

The Compliance Trap: Size Status Can Change Mid-Contract

A business that was small at proposal submission can grow past the size standard during contract performance — and when that happens, the subcontracting plan obligation can kick in on a contract that didn’t originally require one. See our SBA size standards guide for how size determinations work and how often standards get revisited, since a standard changing can also shift your status without any growth on your part at all.

Good Faith Efforts Are Audited

Setting ambitious goals on paper isn’t enough — contracting officers and DCMA can audit whether you made genuine good faith efforts to meet your stated goals, and failing to do so (or failing to report through eSRS on schedule) can affect past performance ratings and future award decisions — and FAR allows the government to include a liquidated-damages clause for failure to make a good-faith effort, a harder financial consequence than a past-performance ding alone. Our FAR flow-down clauses guide covers the related compliance obligations that travel with subcontracting plan requirements once you’re managing subcontractors under a large contract.

Individual Plan vs. Commercial/Comprehensive Plan

Not all subcontracting plans look the same: an Individual Subcontracting Plan covers a single contract with its own specific goals, while a Commercial (Comprehensive) Subcontracting Plan (CSP) covers a contractor’s entire commercial sales for a full fiscal year rather than one contract at a time. Which one you end up filing changes what you actually have to track and report, so confirm with your contracting officer which type applies before building your tracking system around the wrong one.

The 50% Limitation on Subcontracting Still Applies Separately

Don’t confuse the subcontracting plan (a large-business/large-contract compliance document) with the limitations on subcontracting rule that still governs how much work a small business prime must perform itself — these are two entirely separate requirements that can both apply depending on your specific contract. See our 50% subcontracting rule guide for that distinct requirement.

Bottom Line

Outgrowing small business status brings a new compliance layer most contractors never planned for — build your subcontracting plan infrastructure (a named plan administrator, a tracking system, eSRS familiarity) before you need it, not after a contracting officer asks where it is.
