The Corporate Transparency Act created a beneficial-ownership reporting rule that many founders still worry about. Here is what it is, and why a 2025 interim rule now exempts most US-formed companies.
What the Corporate Transparency Act set out to do
The Corporate Transparency Act (CTA) is a US law aimed at combating money laundering and other financial crime by making the true owners of companies visible to the government. It directed the Financial Crimes Enforcement Network — FinCEN, a bureau of the US Treasury — to collect beneficial-ownership information, often abbreviated as BOI.
A "beneficial owner" broadly means an individual who ultimately owns or controls a company. The original design required a wide range of companies to report who their beneficial owners are, so that ownership could no longer be fully hidden behind layers of entities.
- The CTA targets money laundering by revealing who really owns companies
- FinCEN, part of the US Treasury, administers the reporting
- "BOI" means beneficial-ownership information
- A beneficial owner is someone who ultimately owns or controls the company
How the rule originally applied
As first implemented, the rule swept in most small US corporations and LLCs, requiring each "reporting company" to file its beneficial owners' details with FinCEN, with deadlines that depended on when the company was formed. This caused a great deal of concern and confusion for small businesses and their owners.
That original, broad version is the source of most of the anxiety founders still carry about BOI. The important development is that the scope changed significantly in 2025.
The March 2025 interim rule
In March 2025, FinCEN issued an interim final rule that narrowed the requirement dramatically. Under this rule, entities created in the United States — domestic companies — are exempt from the BOI reporting requirement. In practice, US-formed LLCs and corporations no longer file a BOI report under the interim rule.
The reporting obligation was refocused onto certain foreign companies. Only "foreign reporting companies" — entities formed abroad that then register to do business in a US state — fall within the reporting requirement, and even then with adjusted deadlines. For the typical founder forming a company in a US state, the interim rule removed the filing.
- US-formed (domestic) entities are exempt under the interim rule
- Most US LLCs and corporations no longer file a BOI report
- The requirement now focuses on certain foreign reporting companies
- A foreign reporting company is formed abroad and registered in a US state
Who might still need to report
If you formed your company outside the US and then registered it to operate in a US state, you may be a foreign reporting company and should check whether the requirement applies to you. This is a narrower group than the original rule covered.
If, like most founders, you formed a fresh company directly in a US state — a Wyoming LLC or a Delaware corporation, for example — the interim rule treats you as exempt. Because the details turn on how and where your entity was created, it is worth confirming your specific situation rather than assuming.
- Formed a company abroad and registered it in the US? Check the rule
- Formed a fresh US-state entity? Exempt under the interim rule
- The current scope is narrower than the original CTA rollout
- Your obligation depends on where and how the entity was created
Why you should still keep an eye on this
The BOI rule has already changed course more than once — deadlines shifted, enforcement paused, and the scope narrowed. An interim final rule can be revised, and legal challenges can further alter the landscape, so today's exemption is not guaranteed to be permanent.
The practical takeaway: if you formed in a US state, you are currently exempt and do not need to file, but this is an area worth monitoring. This is general information, not legal advice — for a definitive answer on your entity, confirm the current requirement or check with a qualified advisor.
- The rule has already changed several times — it can change again
- An interim rule may be revised or challenged in court
- If you formed in a US state, you are currently exempt from filing
- Treat this as general information and confirm your own situation
