Beneficial Ownership Information (BOI)
Beneficial Ownership Information, or BOI, is the federal filing required under the Corporate Transparency Act that identifies the beneficial owners of most US entities to FinCEN, the Financial Crimes Enforcement Network. In plain terms: most LLCs and corporations have to tell the federal government who really controls them. For a multi-entity owner, that means a separate filing per entity — and ongoing updates whenever ownership, address, or identifying documents change.
Note: BOI requirements have been the subject of evolving litigation and enforcement guidance. Treat this as background; confirm current filing obligations with counsel before filing.
How BOI applies in practice
BOI reporting is filed through FinCEN's BOI E-Filing System on a per-entity basis. The report identifies two categories of people: beneficial owners (those with substantial control or 25%+ ownership) and, for entities formed after the rule's effective date, company applicants (the individuals who filed the entity with the state).
- One report per reporting company. Every non-exempt entity files its own BOI report — not a portfolio-level filing.
- Beneficial owner identification. Anyone with 25%+ ownership interest or substantial control is reported, with full name, DOB, residential address, and an ID document.
- FinCEN identifier option. Owners can apply for a personal FinCEN ID once, then reference it in subsequent filings instead of re-uploading their ID every time.
- 30-day update window. Any change to reported information triggers a 30-day update requirement — a moving residential address alone can put an owner out of compliance.
- Per-entity tracking. For a multi-entity owner, BOI status, filing date, last update, and any pending triggers should be tracked per entity in one place.
Why BOI matters
Civil penalties for willful BOI non-compliance run up to $500 per day, and criminal penalties can reach two years and $10,000. The bigger operational risk for most owners is not the initial filing — most entities get filed once — but the update trap. Move houses, change driver's license numbers, transfer membership interests, add a new owner, dissolve and reorganize an entity, and an unfiled update starts the penalty clock. For a portfolio of five LLCs, the surface area is large and easy to miss.
BOI is one of the most visible examples of a broader pattern in multi-entity operations: compliance does not scale linearly with entity count. Five entities is not five times the BOI work of one; it is five times the surface area for changes, five separate filings to keep current, and five chances to miss a 30-day window. The discipline is per-entity tracking, not just per-entity filing.

Common questions about BOI
Who has to file a BOI report?
Most domestic LLCs, corporations, and similar state-registered entities, plus foreign entities registered to do business in the US. Exemptions exist for large operating companies, regulated entities, and certain other categories — most SMBs are not exempt.
What does a BOI filing include?
For each beneficial owner: full name, date of birth, current residential address, and a unique ID number from an acceptable identifying document (passport or driver's license) with an image of that document.
When do you have to update a BOI filing?
Within 30 days of any change to reported information — ownership, address, name, or identifying document. This is the trap multi-entity owners fall into: filing once and forgetting.
How does AMG handle BOI for multi-entity portfolios?
We build per-entity compliance calendars that track BOI status, ownership-change triggers, and 30-day update windows across an entire portfolio, so nothing falls through the cracks.
