Beneficial Ownership Reporting Under the Corporate Transparency Act
The Corporate Transparency Act reshaped beneficial ownership reporting for US entities. Here is exactly who must file, what data and when.
The Corporate Transparency Act (CTA) made beneficial ownership reporting a federal requirement for most US legal entities and many foreign entities registered to do business in the US. The FinCEN Beneficial Ownership Information (BOI) database, launched in 2024 and matured through 2025, now sits next to OFAC and SAM as a foundational compliance dataset.
Whether you are a reporting company filing your own BOI, a financial institution consuming BOI to support CDD, or a compliance team reconciling customer data, this guide explains exactly what 2026 obligations look like.
Who Must File a BOI Report
Domestic reporting companies — corporations, LLCs and similar entities created by filing with a US state — must file, unless they fall within one of 23 exemptions covering most regulated entities, large operating companies, public companies and certain inactive entities. Foreign reporting companies registered to do business in any US state must also file.
What Information Goes In the Report
For the entity: legal name, trade names, current US address, jurisdiction of formation and a tax identifier. For each beneficial owner and company applicant: legal name, date of birth, residential address, an acceptable identifying document number and an image of that document.
Definition of Beneficial Owner
Any individual who either exercises substantial control over the entity or owns or controls at least 25% of the ownership interests.
Filing Deadlines
Entities formed before 2024 had until the start of 2025 to file. Entities formed during 2024 had 90 days. Entities formed in 2025 and later have 30 days from formation. Updates and corrections are due within 30 days of the change becoming known.
Penalties for Non-Compliance
Civil penalties run up to $591 per day (inflation-adjusted), and willful violations can trigger criminal penalties of up to $10,000 and two years in prison. Senior officers can be held personally liable.
How BOI Interacts With Financial Institution KYC
Financial institutions covered by the FinCEN CDD Rule already collect beneficial ownership at account opening. With customer consent, those institutions can access the BOI database to verify the information the customer provided. Reconciling BOI against your customer-provided data is rapidly becoming a baseline expectation.
Operationalizing BOI in 2026
Treat BOI like any other authoritative source — pull on a schedule, diff against your customer record, raise an exception on mismatch, document the resolution. The institutions that win exams are the ones that can show a clean reconciliation log.

Frequently Asked Questions
Are sole proprietorships covered by the CTA?
Generally no, because they are not created by filing with a state. Single-member LLCs, however, are covered.
Who is the 'company applicant'?
The individual who directly files the document that creates or registers the entity, and the person primarily responsible for directing that filing.
Can financial institutions access the BOI database?
Yes, with customer consent and for permissible purposes such as supporting CDD obligations.
What if ownership changes mid-year?
File an updated BOI report within 30 days of the change.
Is there an annual renewal?
No. Reports are event-driven — initial filing, then updates within 30 days of changes.
