Maintaining the HUBZone Certification

If your business is HUBZone certified and there are no changes during your certification, you have no reporting obligations to SBA. However, you must report all “material changes” to SBA because they may affect your eligibility in the HUBZone Program.

What is considered a "material change?"  For example:

  • Change in the ownership

  • Change in business structure

  • Change in principal office

  • Failure to meet the 35% HUBZone residency requirement

There is no limit to the length of time you are qualified as a HUBZone small business concern. You may remain certified as long as you continue to follow the HUBZone regulations, notify SBA of any changes, and you properly recertify the business.

Report material changes to

The HUBZone office has a 35% and principal office calculator that you can use; but please make sure that before you use it, you review the HUBZone regulatory definition for the terms “principal office” and “employee.”

Recertifying your HUBZone Certification

Even though there is no limit to the length of time you may qualify as a HUBZone firm, your certification is not a lifetime certification.

If you wish to retain your HUBZone certification, you must recertify every three years to SBA, indicating that the firm is still in compliance with all the HUBZone requirements including: its principal office located in a qualified HUBZone; at least 35% of its employees residing in a HUBZone; and it is still a small business concern. 

SBA will send you a notice when it comes time to recertify because there is no mechanism for you to initiate the recertification process.  This means that you may not receive the notice on your 3rd anniversary.  For example, a firm certified on January 2, 2010 may receive the recertification notification on August 20, 2013.  This means that the firm continues to be certified until it is decertified because it no longer meets the HUBZone requirements. 

The decertification reasons vary and include:  the firm does not respond to the recertification notice or to the request of supporting documentation within the time period SBA provides; the firm is found to be out of compliance based on the review of the supporting documentation; or the firm voluntarily decertifies.  Regardless of the reason, a firm that is decertified may seek certification after ninety (90) calendar days from the date of decertification if it believes that it has overcome the reasons for decertification through changed circumstances and is currently eligible.

Voluntary Decertifying your HUBZone Certification

You can voluntarily decertify your HUBZone application at any time by completing the Voluntary Decertification form in the HUBZone Application section and mailing it to:

U.S. Small Business Administration
409 3rd Street SW, 8th floor
Washington, DC 20416
ATTN: HUBZone Program – Voluntary Decertification

If you voluntary decertify your HUBZone application, you may reapply for the HUBZone certification no sooner than 90 days from the date your firm was decertified, providing your business still meets all the eligibility criteria.
