Who must file - A “reporting company” is generally any entity (including LLCs) created by filing formation/registration documents with a state or similar office, unless it qualifies for one of the statutory exemptions. (FinCEN fact sheet) - Each reporting company that is not exempt must file its own BOI report. "Can a parent company file a single BOI report on behalf of its group of companies?" — No. (FinCEN FAQs)

Subsidiary exemption and parent-reporting rules - Subsidiary exemption

A subsidiary may be exempt if it is wholly (100%) owned or controlled, directly or indirectly, by one or more exempt entities listed in the rule. If any ownership interests are held by a non-exempt entity or individual, the subsidiary does not qualify. (FinCEN FAQs L.6) - Special reporting rule: If a reporting company’s beneficial owners only hold their interest through a parent company and that parent company is itself an exempt entity, the reporting company may report the parent company’s name in lieu of beneficial owner details. (FinCEN FAQs C.10/C.7)

Practical filing mechanics for parent–subsidiary LLC clusters - General rule

File one BOI report per non-exempt reporting company. In multi-tier structures, determine exempt status for each entity separately. - Recommended sequence/approach: File the parent’s BOI report first (if the parent is a reporting company and not exempt) to obtain a FinCEN identifier for the parent; then file the subsidiary’s report and, where applicable, report the parent entity (name/TIN or the parent’s FinCEN identifier) as the owner. FinCEN identifiers can be used in place of the four pieces of personal identifying information and FinCEN will link entities when identifiers are reported. (Small Entity Compliance Guide) - If a subsidiary qualifies for the subsidiary exemption, file an updated BOI report marking the entity as "newly exempt" (identify the entity and check the exemption box). (FinCEN FAQs)

Required data and who is a beneficial owner - BOI reports require specific company data, and for beneficial owners the four identifying data elements (full legal name, date of birth, residential or business address, and unique identifying number from acceptable documents or a FinCEN identifier). Beneficial owners are individuals who (1) exercise substantial control or (2) own/ control at least 25% of ownership interests. (Small Entity Compliance Guide) - Company applicants must be reported for companies created or registered on or after January 1, 2024; existing companies generally do not report company applicants. (Small Entity Compliance Guide) 5) Timelines, updates, and corrections - Initial filing deadlines depend on date of creation/registration and regulatory adjustments

FinCEN guidance and subsequent interim rulemaking adjusted deadlines for certain foreign registered companies and existing companies. (Small Entity Compliance Guide; Federal Register rule) For existing reporting companies that lost an exemption, there are transitional deadlines (see citations). - Updates/corrections: If any required information changes, file an updated BOI report no later than 30 days after the change. If a previously submitted report is inaccurate, it must be corrected within 30 days of learning of the inaccuracy; voluntary correction within 90 days of the original deadline may qualify for a safe harbor from penalties. (Small Entity Compliance Guide) 6) Penalties and enforcement - Willful failure to report, or knowingly filing false BOI information, can trigger civil penalties (statutory up to $500 per day, adjusted for inflation — FinCEN cited $591 at one update) and criminal penalties (up to two years imprisonment and/or fines up to $10,000). Senior officers could be held accountable. (Small Entity Compliance Guide; FinCEN FAQs)

State-level interactions and practical notes - BOI reporting is a federal FinCEN requirement tied to whether an entity was formed/registered via a state filing. Changes in state formation/registration (including conversions or changes of jurisdiction) can require updated BOI reports (e.g., name change, jurisdiction change) but states generally do not replace or duplicate FinCEN’s BOI reporting. (FinCEN FAQs)

Recommended compliance checklist for parent–subsidiary LLC clusters - Map the entity ownership tree and document ownership percentages and control mechanisms. - For each entity

determine whether it is a “reporting company” and whether any exemption applies (including subsidiary exemption and large operating company, public utility, etc.). - If filing is required: collect required BOI data for beneficial owners and company applicants (if applicable), obtain FinCEN identifiers for individuals/entities when useful, and file electronically through FinCEN’s secure system. File parent first when using its FinCEN identifier to link to subsidiaries. - Put policies in place to monitor changes in ownership/control, conversions, or changes in exempt status; file updates within 30 days of qualifying changes and correct inaccuracies promptly (safe harbor if corrected within 90 days). - Maintain records and coordinate with counsel or a compliance provider for complex multi-tier or mixed ownership structures.
