Beneficial ownership
A beneficial owner is anyone with 25% or more ownership in the business — regardless of whether the person is a silent partner or listed on your business documentation, involved in managing the business or a signer on accounts.
Please provide the following information about all beneficial owners to your STCU business services representative:
- Full legal name and physical address.
- Date of birth and Social Security or tax identification number (TIN).
- Percentage of ownership in the business.
Beneficial ownership identification must be completed in person or with a photocopy of the person's government-issued identification.
Sole Proprietorships, informal organizations, and nonprofits are exempt from the beneficial ownership requirement.
