Foreign ownership of U.S. companies continues to rise across the Caribbean in 2026. Entrepreneurs from Trinidad & Tobago, Jamaica, Barbados, Guyana, and the wider region are increasingly forming U.S. LLCs—most commonly in Wyoming—to access global clients, USD banking, and international platforms.

With this growth comes stricter IRS oversight.

One of the most critical (and misunderstood) compliance requirements for non-resident owners is IRS Form 5472. This form is mandatory for many foreign-owned U.S. entities and carries severe penalties if missed—even when the company made no profit.

This guide explains who must file Form 5472, how it works in 2026, and how Caribbean founders can stay compliant without risking costly penalties.

What Is IRS Form 5472?

IRS Form 5472 is titled:

“Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business.”

It is an information return, not a tax payment form.

Form 5472 is used to report transactions between a U.S. entity and its foreign owner or other related foreign parties. The IRS uses this form to monitor:

• Foreign ownership
• Cross-border money flows
• Transfer pricing and profit shifting

Even if your U.S. company:

• Made no money
• Had no U.S. customers
• Was fully operated from the Caribbean

👉 Form 5472 may still be required.

Why the IRS Requires Form 5472

The IRS uses Form 5472 to:

• Ensure transparency between U.S. companies and foreign owners
• Detect underreported income or disguised transactions
• Monitor compliance with U.S. tax law

In 2026, foreign-owned single-member LLCs are one of the most heavily audited entity types—mainly because many founders are unaware of this filing requirement.

Who Must File Form 5472?

You must file Form 5472 if any of the following apply:

1. You Own a U.S. LLC as a Non-U.S. Person

This includes:

• Caribbean citizens
• Non-resident aliens
• Foreign companies owning U.S. entities

A single-member Wyoming LLC owned by a foreign person is considered a foreign-owned disregarded entity and is required to file Form 5472.

2. Your U.S. Entity Is at Least 25% Foreign-Owned

This applies to:

• U.S. corporations
• Multi-member LLCs taxed as corporations

If a foreign person or foreign company owns 25% or more, Form 5472 applies.

3. There Were Reportable Transactions

A reportable transaction includes almost any movement of value, such as:

• Owner capital contributions
• Loans to or from the company
• Reimbursements
• Service payments
• Management fees
• Rent or royalty payments

⚠️ Even a $1 transfer can trigger the filing requirement.

Critical 2026 Update for Foreign-Owned LLCs

In 2026, the IRS continues to enforce the rule that:

Foreign-owned single-member LLCs must file Form 5472 even if they had no income.

These LLCs must file:

• Form 5472
• A pro-forma Form 1120 (blank return used as a cover sheet)

Failure to do so results in automatic penalties.

Key Components of Form 5472

Form 5472 requires disclosure of:

1. Reporting Entity Information

• Legal business name
• U.S. address
• EIN

2. Foreign Owner Information

• Name and address
• Country of residence
• Ownership percentage

3. Reportable Transactions

Including:

• Cash contributions
• Loans
• Payments for services
• Interest, royalties, rent
• Non-cash or below-market transactions

⚠️ Both monetary and non-monetary transactions must be reported.

Filing Deadlines (2026)

For most Caribbean-owned U.S. companies:

• Deadline: April 15, 2026 (calendar-year entities)
• Extension: File Form 7004 for an automatic 6-month extension (to October 15, 2026)

Form 5472 is filed together with:

• Form 1120 (or pro-forma 1120 for disregarded entities)

How to File Form 5472

Filing Method

• Electronic filing via IRS Modernized e-File (MeF) is standard
• Some foreign-owned disregarded entities may still require paper filing, depending on structure

Because filing rules vary by entity type, professional handling is strongly recommended.

Penalties for Not Filing Form 5472

The penalties are severe and automatic.

2026 IRS Penalties

• $25,000 per year, per missed or incomplete Form 5472
• Additional $25,000 every 30 days after IRS notice
• Separate $25,000 penalty for failure to maintain records

💡 Many Caribbean founders receive penalties even when their LLC never traded.

Record-Keeping Requirements

The IRS requires you to maintain:

• Bank statements
• Accounting records
• Owner transaction logs
• Loan agreements (if applicable)

Failure to maintain records can trigger additional penalties, even if the form was filed.

Best Practices for Caribbean Founders in 2026

• Track all owner transactions (even reimbursements)
• Separate personal and business funds
• Maintain clear ownership documentation
• File extensions if unsure—never skip filing
• Work with professionals experienced in non-resident Wyoming LLCs

Common Mistakes Caribbean Entrepreneurs Make

• Assuming “no income = no filing” ❌
• Ignoring capital contributions ❌
• Filing late without extension ❌
• Using U.S. accountants unfamiliar with foreign-owned LLC rules ❌
