A plain-English answer to who has to file, who is exempt, what the current deadlines look like, and what to do if the original window has already passed.
The Corporate Transparency Act requires most domestic LLCs and corporations (and foreign entities registered to do business in the United States) to file a Beneficial Ownership Information Report with FinCEN. The report identifies every individual who owns 25% or more of the entity or exercises substantial control. Civil penalties run up to $591 per day, capped at $10,000, plus a criminal exposure of up to two years and another $10,000 for willful failure. Enforcement has been on a litigation roller coaster since late 2024 (Texas Top Cop Shop, Garland v. NSBA, multiple injunctions), and the practical posture has shifted more than once. Filing remains the safe-harbor move regardless of where the injunction calendar lands on any given week. If you have not filed, the right next step is to confirm whether your entity is covered, run the 23 exemption tests, and file. The process itself takes about 20 minutes per entity.
The Corporate Transparency Act defines a "reporting company" as any entity created by filing a document with a Secretary of State or similar office. In practical terms that captures:
What is NOT captured: sole proprietorships with no entity, general partnerships formed without a state filing, and trusts (unless the trust itself filed with a state to come into existence, which most do not).
The default position is "you must file." The work is identifying whether you fall into one of the 23 listed exemptions. Most owner-operated small businesses do not, which is why the rule sweeps in millions of entities that historically never had a federal beneficial-ownership obligation.
There are 23 exemptions in total. The handful that most often apply to ordinary operating businesses:
If none of the 23 fits cleanly, file. The cost of filing is 20 minutes; the cost of being wrong is per-day penalties and potential criminal exposure.
The original deadlines, as written in the regulations:
Enforcement has whipsawed. Texas Top Cop Shop, Inc. v. Garland (5th Circuit, late 2024) and the subsequent Garland v. NSBA injunction created stretches where FinCEN paused active enforcement and stretches where the rule was in full effect. The Treasury Department announced in March 2025 that it would not pursue penalties against domestic entities under the prior regime while the rule was rewritten to focus on foreign reporting companies. The interim rule and any follow-on rulemaking remain subject to further litigation.
The practical guidance has not changed: filing remains the safe-harbor move. The cost of filing is trivial. The cost of being on the wrong side of a re-tightened rule is not. Confirm the current enforcement posture at fincen.gov/boi before filing or pausing.
The statutory penalty structure for willful failure to file or for filing false information:
The catalog Signal uses to score these on inbound diagnostics carries a typical exposure range of $5,000 to $50,000 per reporting company, depending on how many missed updates compound and how many related entities sit under the same ownership. A holding-company structure with five operating LLCs, every one of which missed the original deadline and never updated for a subsequent ownership change, can stack penalties across all six entities at once.
The criminal piece is rare in practice for ordinary operating businesses and was designed to deter willful concealment, not penalize busy small-business owners. The civil piece is real and the per-day clock keeps running until the report is filed.
BOIR is a FinCEN obligation, not an IRS obligation. It does not appear on your 1040, your 1120, your 1120-S, or your 1065. Your tax return is silent on whether the filing was made. This is one reason it is the most-missed compliance item in the Signal catalog: the standard return-prep cycle never touches it.
The easiest direct check: log into boiefiling.fincen.gov with the entity's EIN. If a report was filed, the system will show it. If nothing comes up, no report was filed, and the question is whether your entity needed to file in the first place.
A practical entity-by-entity audit takes about an hour for a portfolio of five LLCs. Walk each entity through:
The filing happens on the FinCEN BOI E-Filing portal at boiefiling.fincen.gov. The report itself is short:
For an owner-operator LLC with one beneficial owner, the filing takes 15 to 20 minutes once you have a clean ID image. For a multi-member or holding-structure entity it scales linearly with the number of beneficial owners.
The portal generates a unique FinCEN ID for each beneficial owner. Saving that ID locally lets you reuse it across related entities (a beneficial owner of five LLCs only needs to upload their ID once and then reference the FinCEN ID on each subsequent filing).
The BOIR is a non-tax compliance obligation. It sits outside the IRS, outside the state tax authorities, and outside the normal return-prep cycle. Most generalist preparers correctly view it as not their work product. Some pushed clients to file in late 2024 and then stopped after the injunction. Others never raised it.
The result is that ownership of the filing falls into a gap. The CPA does not own it because it is not on a tax return. The attorney who formed the entity does not own it because formation was a one-time engagement. Bookkeepers do not own it because it does not touch the books. Operators assume someone professional must be handling it. Often, nobody is.
The "second opinion" frame catches this even when the tax return looks fine. Signal's free return diagnostic checks BOIR status as part of the broader compliance scan, alongside the deduction and structural items elsewhere in the catalog.
