Review the March 26 2025 interim final rule (Federal Register 2025-05199): as of that date, domestic U.S. entities are fully exempt from BOI reporting; only foreign entities registered to do business in a U.S. state or tribal jurisdiction remain subject to reporting
For covered foreign entities, submit initial BOI reports via the BOI E-Filing system at https://boiefiling.fincen.gov using the structured XML filing format or the web-based BOIR form
Populate required fields: legal entity name, jurisdiction of formation, EIN or foreign TIN, U.S. registered agent address, and for each beneficial owner: full legal name, date of birth, residential address, and unique identifying document number
For entities registered in the U.S. before March 26 2025, the filing deadline was April 25 2025; for entities registered on or after March 26 2025, the deadline is 30 calendar days from effective registration
Update filings within 30 days of any change to reported beneficial owner information (name, address, document number)
For third-party filing on behalf of a client, use the third-party preparer fields in the BOIR XML schema and retain a copy of the executed authorization document
Known gotchas
As of the March 2025 interim final rule, domestic U.S. entities (LLCs, corporations, etc. formed under U.S. law) are fully exempt from BOI reporting; building automated domestic-entity submission flows is no longer required for CTA compliance
FinCEN has not released a public machine-to-machine API for BOI queries or submissions; the boiefiling.fincen.gov system accepts XML uploads or manual form entry only — third-party filing APIs (e.g., TaxBandits) wrap this portal, they do not call an official FinCEN REST API
The Eleventh Circuit affirmed the CTA's constitutionality in January 2026 but the domestic exemption remains; litigation could still alter scope — verify FinCEN's news releases before advising clients on compliance obligations
