From who needs to file this form, to what it entails, and the potential consequences of non-compliance, we aim to provide a comprehensive overview. Whether you are a business owner with foreign connections, or a tax professional advising international clients, gaining a thorough understanding of Form 1120-F will be invaluable in ensuring legal compliance and optimizing tax strategies.

What is a foreign corporation for US tax purposes?

The definition of a foreign corporation is straightforward enough: A corporation registered  outside the United States. 

But, why would a foreign-registered business be worried about US tax law, you might ask? There are many reasons that a foreign corporation might have US tax reporting requirements, despite their place of incorporation being abroad.

A US tax reporting requirement can be triggered if, the foreign corporation has some type of business connection with the US (more on that next).

But first, what are some examples of foreign corporations? A foreign corporation can take many forms, even within the same country, based on variations in structure and ownership. Some examples of foreign corporations include:

  • Aktiengesellschaft (AG) in Germany
  • Società per Azioni (S.p.A.) in Italy
  • Public limited company (plc) in the United Kingdom
  • Sociedad anónima (S.A.) in Colombia

Since there may not be a 1-to-1 equivalent of a US corporation in your country, generally any foreign corporate structure with shareholders who have limited liability will meet the criteria of a foreign corporation under US law. 

Important to bear in mind:

Even if your foreign corporation has non-US owners, it may still need to report to the IRS.

Which corporations have to file IRS Form 1120-F?

Business owners with a foreign registered corporation that meets certain criteria have to file Form 1120-F.1 According to the IRS, “A foreign corporation files Form 1120-F to report their income, gains, losses, deductions, credits, and to figure their U.S. income tax liability.” 

These include if:

  • the corporation was engaged in a trade or business in the US
  • the corporation had income, gains, or losses that were ‘effectively connected’ to trade or business in the US
  • the corporation had income from a US source that wasn’t subject to withholding tax at source
  • the corporation overpaid US tax and needs to claim a refund
  • the corporation wants to claim any US credits or benefits
  • the corporation wants to claim the benefit of a US international tax treaty (Form 8833 must also be filed).

The term ‘effectively connected’ generally refers to when a foreign corporation has premises, production, or employees in the US.

Pro tip:

If you’re unsure whether your foreign registered business has to file Form 1120-F, a US expat tax specialist can provide clear guidance.
