What EU Businesses Need to Know about the U.S. Corporate Transparency Act

Suppose you are considering expanding your business to the United States or have already entered the U.S. market. In that case, you may need to comply with the Corporate Transparency Act (CTA), which came into effect on January 1, 2024.
The CTA requires most non-U.S.-formed businesses that are registered to do business in the United States to file a Beneficial Ownership Information (BOI) report with the Financial Crimes Enforcement Network (FinCEN), with some exceptions.
The purpose of the CTA is to provide the U.S. federal government with greater transparency on business ownership, primarily to combat money laundering and other illicit activities. This requirement is similar to Ultimate Beneficial Owner (UBO) registers that many countries, including EU member states, have already implemented. Similarly, non-compliance with the CTA carries serious consequences, including civil and criminal penalties for failure to report for the company and its responsible individuals.
Who Must File?
If your EU business is operating in the United States as a registered foreign entity, you likely need to comply with the CTA as a Reporting Company:
- Non-U.S. businesses, such as a Czech s.r.o., a German GmbH, or other foreign entities, that are registered to do business in the United States (e.g., as a foreign corporation or foreign LLC) are required to file a Beneficial Ownership Information (BOI) report with FinCEN.
The BOI filing requirement does not apply if your EU business:
- Falls within the 23 exemptions for specific types of entities, such as banks, insurance companies, and large operating companies, or
- Has only U.S. persons as beneficial owners.
Also, under the Interim Final Rule published on March 21, 2025, domestic entities, such as Delaware corporations, are no longer required to report, regardless of ownership, as they have been temporarily excluded from the definition of "Reporting Company."
What to File?
If your EU business is subject to CTA reporting, you must provide the following in a BOI report:
- Business name(s)
- U.S. address for the business
- Jurisdiction of formation and state of U.S. registration
- Taxpayer Identification Number (TIN)
- Personal details of beneficial owners, anyone who exercises substantial control or owns at least 25% of the company, including:
- Full legal name
- Date of birth
- Residential address
- Copies of identification documents (e.g., passport or government-issued ID)
For companies registered after January 1, 2024, the company applicants (individuals involved in the company’s registration process) must also be disclosed unless they are U.S. persons.
When to File?
The BOI reporting deadline has been extended to April 20, 2025, for already registered Reporting Companies, previously set to March 21, 2025. For newly registered Reporting Companies it is 30 days from the date the entity registers to do business in the United States, whichever is later.

"Following a devastating hotel fire in Prague, the law firm Holubová advokáti, led by attorney Klara Dvorakova, successfully represented our extended family as a group of victims. The firm navigated complex international insurance and compensation laws to defend our rights.
I would like to acknowledge the extraordinary efforts the firm had to make to bring our case to a successful compensation under extremely difficult circumstances."

"A visit to her daughter in London turned Eva's life upside down when she says she stepped into a crossing on a green light but was hit by a car. Despite her remarkable bravery, she faced a long treatment due to fractures in her pelvis, and the associated limitations and pain are likely to persist for the rest of her life. Regular headaches and impaired concentration compound her challenges.
Eva contacted us through an organization temporarily helping her manage her difficult living situation. At that time, she was destitute, relying only on subsistence payments. We were able to assist her because we specialize in personal injury and have contacts with proven colleagues abroad.
We worked with Stewarts, a UK law firm, on this case. Attorneys Klára Dvořáková and Rebecca Huxford helped Eva with the documentation in her case, explaining her options and the differences between the Czech and British systems of healthcare and social benefits reimbursement. Within a few months, thanks to the professional cooperation between the two offices, an offer of compensation from the insurance company of approximately CZK seven million was achieved. The client accepted this settlement because she did not want to deal with courts in the United Kingdom.
Subsequently, we assisted the client with related tax issues and contacted Auditone, a tax consultancy firm, which arranged for the filing of a tax return. Compensation for lost income is taxable, unlike most personal injury compensation.
'No one has done as much for me as you,' Eva said.
The fact that we were able to help Eva gives our work meaning and brings us great joy. We are very happy that, thanks to our many years of active involvement in the international professional organization PEOPIL, we can cooperate on such cases."
