The Financial Crimes Enforcement Network (FinCEN) requires all businesses to file Beneficial Ownership Information. A beneficial owner is any individual who exercises substantial control over the company, or any individual who owns more than a 25% interest in the company. If you have any questions about who qualifies as a beneficial owner, you can check FinCEN’s compliance guide, starting at page 16: https://www.fincen.gov/sites/default/files/shared/BOI_Small_Compliance_Guide.v1.1-FINAL.pdf
