You’re a U.S. Owner of a Foreign Corporation. Your Tax Obligations Are Unique.

Complex reporting rules, ownership thresholds, entity classification, and anti-deferral regimes make foreign business taxation uniquely challenging. If you’re unsure what to file, what counts as income, or how to avoid penalties, you’re in the right place.

Does This Sound Like Your Situation?

If you own a business abroad, you’ve probably discovered that the U.S. treats foreign corporations very differently from domestic ones. Many Americans in your position come to us feeling unsure about what they’re required to report, how their ownership is classified, or whether they’re at risk for penalties. If any of the following sound familiar, you’re not alone:
  • You manage a company overseas but aren’t sure which U.S. forms you’re responsible for or how your ownership percentage affects what you must report.

  • Form 5471 feels impossible to interpret, and you worry that missing even one schedule could trigger penalties.

  • GILTI, Subpart F, basis calculations, previously taxed earnings, you’re not confident how these rules apply to your business.

  • You’re unsure when foreign profits are considered U.S.-taxable, how to classify your entity, or whether treaty benefits apply.

  • You want to make smart decisions around dividends, retained earnings, or restructuring, but don’t have clear guidance.

  • Above all, you want to stay compliant without spending hours deciphering regulations that were never written with everyday business owners in mind.

Trusted by Americans Running Businesses Around the World

What a great experience from start to finish! i had an excellent CPA who always helps me through my tax situation. Working overseas, owning a business, and owning property can get complicated, but she made the process effortless and was always able to accomplish everything in a timely manner.
I’ve used Greenback to prepare my US taxes for several years and never had an issue. I needed help because I owned a foreign business which made my US taxes a nightmare. They helped a lot. Recommended.
Second year in a row I have used Greenback Expat Tax Services. Extremely happy with the knowledge level of my advisor/preparer. I started up a consulting business and Greenback handled all of the extra US reporting that was needed with ease. I whole-heartedly recommend Greenback. I am an experienced Finance professional (CFO) but know that in this area, I rely on the professionals at Greenback to make my declaration smooth and easy. 5 STARS!!
I have been using Greenbacktaxservices for many years now. It have been great overall experience. My accountant has guided me through the years with both my personal and business taxes. I will continue to use her services in the future.
I have found Greenback CPA’s to be professional, courteous, diligent and timely in my relationship with them. I am a small business owner with a FBAR requirement, two state annual returns and standard Federal 1040 and 1120S annuals; and I am quite satisfied with Greenback keeping up with my filing responsibilities
I have worked with my Greenback accountant for years. She is very thorough, is very patient at explaining the tax issues. No easy task this year as it involves my business overseas and in a transition year for retirement. I am very grateful to her as she took the initiative to contact me, since I was almost too late, busy with many other issues. We worked through a dynamic year in record time. My part was easy as my accountant communicates well any changes, and answers my queries timely.

Foreign Business Owner Tax FAQs

If I Run a Business Overseas, When Does Form 5471 Apply to Me?

Form 5471 is the Information Return of U.S. Persons With Respect to Certain Foreign Corporations. If you own 10% or more of a foreign corporation, you must file it annually. Penalties for failure to file start at $10,000 per form.

Form 5471

What Is GILTI and How Does It Affect My Foreign Business Income?

Global Intangible Low-Taxed Income (GILTI) is a complex U.S. tax on certain foreign corporation earnings. We calculate GILTI and apply the Section 250 deduction or the high-tax exception to minimize your liability.

GILTI and Subpart F Income

 

If My Foreign Corporation Pays Taxes Overseas, Can I Benefit From Foreign Tax Credits?

Yes. You may be able to claim a Foreign Tax Credit to prevent double taxation on the same income. Corporations use Form 1118 to claim credits for foreign taxes paid.

What Happens if I Choose the Wrong Classification for My Foreign Entity?

Entity classification has significant U.S. tax consequences. We advise on Check-the-Box elections (Form 8832) to ensure your entity is classified optimally for your situation (e.g., as a corporation, partnership, or disregarded entity).

Entity Classification Election (Form 8832)

What Are the Penalties for Not Filing Form 5471 or Form 5472?

Penalties start at $10,000 per form per year and can escalate to $50,000 for continued non-compliance. These are disclosure penalties that apply even if your business owes no tax.

Form 5471 vs 5472 penalties

Do I Need to File Form 5471 if My Foreign Business Didn’t Make Any Money?

Yes. Form 5471 is an information return that must be filed annually regardless of whether the corporation generated income or losses, as long as you meet the ownership thresholds.

If I Missed Form 5471 in Past Years, Can I Still Get Back in Compliance?

Yes. We help you catch up through the Streamlined Filing Procedures. When you include your delinquent Form 5471s as part of a complete Streamlined submission, the IRS generally does not assess penalties as long as your failure to file was non-willful.

Streamlined won’t automatically erase Form 5471 penalties on its own, but filing through this program is the clearest path to penalty relief for most expats.
