U.S. · SBA size rules
SBA recertification as a small business
The triggers, the deadlines and the effect.
Recertification of size and status is required within 30 calendar days of a merger, acquisition or sale by or of a concern or an affiliate that results in a change in controlling interest (13 CFR 125.12(a)). Long-term contracts require recertification no more than 120 days before the end of the fifth year and before options. Separately, a firm found other than small can ask SBA to recertify it under 13 CFR 121.1010.

Two different things called recertification
Two sets of rules use the word, and mixing them up causes mistakes. The first is contract recertification under 13 CFR 125.12, which protects the government's small business goaling and the integrity of set-asides when a small business awardee changes. The second is the application under 13 CFR 121.1010, which lets a firm that SBA found to be other than small ask to be treated as small again after a significant change. This page covers both, from the eCFR text with issue date October 29, 2026.
What triggers contract recertification
Under 125.12(a), a concern must recertify its size and small business program status (8(a), HUBZone, WOSB/EDWOSB or SDVOSB) within 30 calendar days of a merger, acquisition or sale of or by the concern or an affiliate that results in a change in controlling interest. If both the concern and the acquirer hold small business awards, each must recertify, and for joint ventures the partner involved in the transaction must recertify. For contracts and orders lasting more than five years including options, paragraph (b) requires recertification no more than 120 days before the end of the fifth year and no more than 120 days before exercising any option after that. A contracting officer may also ask for recertification earlier, and paragraph (c) requires it where the officer explicitly asks offerors to recertify in response to a solicitation for a set-aside or reserved order or agreement. A recertification is measured against the size standard in effect at the time of recertification for the NAICS code originally assigned to the award. One exception: no recertification is needed when an entity-owned concern (at least 51 percent owned by a tribe, an Alaska Native Corporation or a CDC) changes to or from wholly-owned status by the same entity.
Effect of recertifying
A qualifying recertification means the concern is generally treated as small, or as a program participant, for up to five years from the date of recertification, and it stays eligible for set-aside or reserved awards unless a later recertification disqualifies it. A disqualifying recertification has several outcomes depending on the case. If the trigger occurs within 180 days after the date of an offer but before award, the concern is ineligible for the pending set-aside award and must tell the contracting officer. If it occurs more than 180 days after the offer, the concern is eligible for a pending single award, which can count as a small business award for goaling for up to five years, but not for a pending multiple-award small business set-aside. If recertification is requested for one order under a set-aside multiple award contract and it fails, the firm is ineligible only for that order and remains eligible for other set-aside and unrestricted awards. Options on a single-award set-aside or unrestricted award can still be exercised after a disqualifying recertification, though the agency cannot count them as small business awards. Recertification does not change the terms of the award: the limitations on subcontracting, nonmanufacturer and subcontracting plan requirements stay in effect, although a contracting officer may require a subcontracting plan if size changes from small to other than small.
The delayed-effective-date provision
Paragraph (g) delays some of the stricter outcomes. A firm with a disqualifying recertification due to a merger, acquisition or sale before January 17, 2026 remains eligible for orders under an underlying small business multiple award contract, but the agency cannot count new or pending orders toward goals. Likewise, a firm with a disqualifying recertification before the end of the fifth year of a long-term contract remains eligible for options exercised before January 17, 2026. Because that date has passed as of the eCFR issue date used here, those transition rules matter mainly for events that occurred before it; newer events fall under the full paragraph (e) rules.
Asking SBA to recertify you
Section 121.1010 is the route back after an adverse size determination. A concern may request recertification at any time by filing an application with the Government Contracting Area Office responsible for the area of its headquarters, wherever its parents or affiliates are. No form is prescribed for the application, but it must be accompanied by a current completed SBA Form 355 and information sufficient to show a significant change in ownership, management or other factors bearing on its status. Recertification is not required, and the bar on future self-certification does not apply, if the adverse determination rested solely on affiliation limited to a particular procurement or sale, such as an ostensible subcontractor or a nonmanufacturer rule violation. A denial is a formal size determination that the SBA Office of Hearings and Appeals may review at its discretion. A grant has future effect only, and notice goes only to the applicant.
Worked example
A small business wins a five-year small business set-aside on March 15, 2026. Under the tool's reading, the fifth year ends March 14, 2031, so the 120-day window opens on November 14, 2030. If a larger firm acquires the contractor on November 2, 2026, recertification is due by December 2, 2026, 30 calendar days later. If the contractor qualifies, that recertification lasts up to five years from the recertification date.
What the rules do not say
The rule does not tell you how to compute size for the recertification; that follows the receipts and employee pages (receipts, employees) and the date rules at size determination date. It does not say how the fifth year is counted if the award has an unusual start, so the tool shows its assumption. Confirm the dates with the contracting officer.

Frequently asked questions
When must I recertify my size?
Within 30 calendar days of a merger, acquisition or sale of or by the concern or an affiliate that changes the controlling interest, and for long-term contracts no more than 120 days before the end of the fifth year and before each later option (13 CFR 125.12).
How long does a qualifying recertification last?
Generally up to five years from the date of recertification, unless a later disqualifying recertification occurs (125.12(e)(1)).
How do I ask SBA to recertify me as small after a size determination?
File an application with the Government Contracting Area Office for your headquarters, with a current SBA Form 355 and information showing a significant change in ownership, management or other factors (121.1010(a)).
Does recertifying cancel my contract?
No. Recertification does not change the terms of the award, though a failed recertification can make you ineligible for pending set-asides and affects goaling credit.
Is a denial final?
A denial is a formal size determination that the SBA Office of Hearings and Appeals may review at its discretion (121.1010(c)).
