When is SBA size status determined?

The default: the date of the offer

Section 121.404(a) sets the baseline. A concern, including its affiliates, must qualify as small under the NAICS code assigned to the contract as of the date it submits a written self-certification that it is small to the procuring activity as part of its initial offer or response which includes price. The practical lesson is that the clock stops at one moment. What your receipts or headcount look like on that date, averaged over the period of measurement, is what counts, and growth after that moment generally does not take away a contract you already won. The rule says once awarded as a small business, a firm is generally considered small for the life of that contract, which is why recertification rules (see the recertification page) are the exceptions to learn.

Multiple award contracts and orders

For a multiple award contract with one NAICS code, SBA measures as of the initial offer including price; with several NAICS codes assigned to discrete categories, it measures each category you bid on, using that category's size standard. Where price is not required in the initial offer, the date is the initial offer without price. Orders are more detailed (paragraph (c)). An order set aside for small business under an unrestricted multiple award contract is measured at the initial offer including price for that order. An order under a contract that was itself set aside or reserved for small business is measured at the initial offer for the underlying contract, unless the contracting officer requests recertification for the specific order, in which case it is measured at the offer for that order, and only for that order. A holder that has grown out of small status and cannot recertify for one order may still qualify for other orders where recertification is not requested. FAR part 13 agreements, GSA Federal Supply Schedule orders and 8(a) sole source orders each have their own exceptions in (c)(3) and (c)(4).

Applying to an SBA program

Paragraph (d) covers applicants for 8(a), HUBZone, women-owned and service-disabled veteran-owned certification. They must be small as of the application date and, where SBA requests a formal size determination, that date too. For 8(a), the size standard is the one for the applicant's primary industry classification; for the other programs it is the standard for any NAICS code listed in the SAM profile. SBA accepts the size representation in SAM unless evidence indicates the concern is other than small, and it requests a formal size determination under 121.1001(b)(8) if information calls it into question. Certificate of competency applicants are measured at the date of application (paragraph (e)).

Other fixed dates

Compliance with the nonmanufacturer rule, the ostensible subcontractor rule and joint venture agreement requirements is determined as of the final proposal revision for negotiated acquisitions and final bid for sealed bidding (paragraph (f)). For a subcontract, the date is the date you certify for the subcontract, under the size standard in effect then, and a prime may rely on the certification unless it has reason to doubt it (paragraph (g)). For architect-engineering, design/build and two-step sealed bidding, it is the initial bid or proposal, with or without price (paragraph (h)). A follow-on or renewal contract is a new contracting action, so the date resets to the new initial offer including price (paragraph (j)). Paragraph (c)(4)(iii) says size is determined on the date of recertification when recertification is required under 125.12(a) and (b), or on the date of the initial offer with price if the contracting officer requests it under 125.12(c).

Worked example

A firm submits a proposal with pricing on March 1, 2026 and certifies it is small. It wins in June. In October it is acquired by a larger company. The award was measured as of March 1, so the award itself stands; the acquisition may trigger recertification within 30 calendar days under 125.12(a), and the contract is not re-measured at the offer date again. Had the firm instead been acquired in the same week as its offer, the acquirer's receipts would be counted at the offer date, because 121.104(d)(2) aggregates a firm that has acquired or been acquired as an affiliate before the date it self-certified, across the whole period of measurement.

What the rule does not say

Section 121.404 does not fix the size standard; the contracting officer picks the NAICS code in the solicitation (121.402), and the standard in effect on the solicitation date applies unless the officer amends the solicitation to use a new one before offers are due. It also does not decide whether you are small, only when to measure. Pair it with the receipts and employee pages for the numbers themselves.
