BOI Report Deadline 2026: When to File and What Happens If You Miss

The BOI report was created by the Corporate Transparency Act to identify the real human owners behind US companies. When it launched in January 2024, almost every small LLC and corporation had to file. That changed on March 26, 2025, when FinCEN issued an interim final rule that removed all US-formed entities from the definition of a reporting company. As a result, the BOI report now applies only to foreign reporting companies — entities formed abroad that register to do business in a US state.

For a foreign-owned single-member LLC formed in Wyoming, Delaware, or any US state, there is no longer a BOI deadline to track. For the full breakdown of who is and is not covered, read our beneficial ownership information report guide.

The key dividing line is where the entity was formed, not who owns it. A US LLC owned 100% by a non-US person is still a domestic entity, so it falls under the exemption. Only a company organized under the laws of a foreign country that then registers with a US Secretary of State remains a reporting company.

Even though the BOI burden is gone for these LLCs, the IRS obligations are not. See BOI report filing for foreign-owned LLCs for the practical detail.

The interim final rule gave existing foreign reporting companies a short 30-day window running to April 25, 2025. Going forward, a newly registering foreign company starts its 30-day clock from the date it receives actual or public notice that its US registration is effective. An updated or corrected report is due within 30 days of any change.

The Corporate Transparency Act sets a daily civil penalty for willful violations, originally $500 per day and now adjusted for inflation to roughly $591 per day. On top of that, a willful failure can bring criminal fines up to $10,000 and imprisonment up to two years. The word that matters is willful: an honest, non-willful mistake is not penalized the same way.

Why most foreign-owned LLC owners no longer face this risk

Because US-formed entities are exempt after the March 2025 rule, the daily penalty simply does not apply to a foreign-owned US LLC — there is no filing obligation to violate. The penalty exposure now sits with foreign reporting companies that ignore their 30-day window.

It is easy to confuse the two because both involve foreign ownership of a US company, but they serve different laws and different regulators. The BOI report discloses the human beneficial owners to FinCEN for anti-money-laundering purposes. Form 5472 discloses dollar transactions between the LLC and its foreign owner to the IRS for transfer-pricing purposes.

Dropping the BOI requirement removed one filing, but the bigger annual obligation remains. A foreign-owned single-member LLC is treated as a corporation for reporting under T.D. 9796 (effective for tax years beginning on or after January 1, 2017), so it files Form 5472 attached to a pro forma Form 1120. Because forming and funding the LLC moves money between the owner and the company, there is almost always a reportable transaction in the very first year.

A foreign-owned disregarded entity cannot e-file. The package must be mailed to P.O. Box 149342, Austin, TX 78714-9342, or faxed to 855-887-7737 — those are the only two accepted methods. The Form 5472 penalty is far steeper than BOI: $25,000 per form, per year, with no cap and no statute of limitations (IRC §6038A(d); §6501(c)(8)), and another $25,000 every 30 days after a 90-day IRS notice. Start on our apply page and we handle the whole filing.

With BOI gone for US-formed LLCs, the deadline that actually matters in 2026 is the April 15 Form 5472 deadline — the 15th day of the 4th month after a calendar-year ends. A timely Form 7004 pushes the filing date to October 15, 2026, but a disregarded entity has no entity-level tax to pay, so the extension is purely about time to file.
