When your US business starts serving customers or hiring people abroad, the structure you choose decides more than the name on the contracts. It decides which US returns you file, when US tax applies to foreign profits and how foreign tax interacts with it. There are three common shapes: a foreign branch of your existing company, a foreign subsidiary, or a separate holding company that owns the international operations. Each can be right. None is right by default.

This is general information. Your CPA and counsel confirm the details for your case.

A foreign branch: one company, two countries

A branch is your US company operating abroad. There is no new foreign corporation, and for US purposes the branch's results belong to the US company. The IRS uses Form 8858 for US persons that operate a foreign branch or own a foreign disregarded entity. 1 A foreign branch for these purposes also includes a foreign qualified business unit, and failing to file the form carries a $10,000 penalty per annual accounting period, with continuation penalties up to $50,000. 1

Foreign tax paid by a branch is tracked separately. The foreign tax credit limitation is applied separately to foreign branch income, among other categories. 2 Ask your CPA how that separate category interacts with your other foreign income before you assume a foreign tax bill simply offsets US tax.

A similar result can come from an election. A foreign eligible entity with a single owner can elect to be disregarded as an entity separate from its owner, and Form 8858 also covers foreign disregarded entities. 3, 1 Not every foreign entity can make that choice. Some are always corporations, including the Panama Sociedad Anonima and the Paraguay Sociedad Anonima. 4

A foreign subsidiary: a separate company with US strings

A subsidiary is a foreign company that your US company or its owners hold. It gives you a separate legal entity in the market, which can matter to local partners, banks and regulators. It also brings the controlled foreign corporation rules. A foreign corporation is a CFC when US shareholders, each holding at least 10%, together own more than 50% of the vote or value. 5, 6

For a CFC, US tax can arrive before any profit is distributed. Each US shareholder includes its share of the CFC's net CFC tested income in gross income. 7 When profits are paid up as dividends, a domestic corporation that is a US shareholder can generally deduct the foreign-source portion of a dividend from a specified 10-percent owned foreign corporation. 8 That deduction is written for domestic corporations, which is one reason ownership through a US company and ownership in your own name produce different results. The federal corporate rate itself is 21% of taxable income. 9

The reporting cost is fixed. A controlling US owner files Form 5471 for the subsidiary, and missing the required information on a foreign corporation carries a $10,000 penalty per annual accounting period, with further penalties after IRS notice capped at $50,000. 10, 11 Moving equipment, intellectual property or other assets into the new company can also require Form 926. 12

Pricing between related companies

Whichever shape you choose, transactions between your US business and its foreign arm are tested against an arm's-length standard. In determining the true taxable income of a controlled taxpayer, the standard in every case is that of a taxpayer dealing at arm's length with an uncontrolled one. 13 In practice, that means written intercompany agreements and prices you can defend, set before the invoices start.

A separate holding company above the operations

A third option places a holding company above your international subsidiaries, often in a jurisdiction chosen for its legal system, banking and treaty position rather than for the operating market. The holding company does not remove the US analysis. If US shareholders own more than 50% of it, it is a CFC like any other foreign corporation. 5

The holding company's own tax depends on where it sits. In the UAE, for example, the corporate tax regime applies to financial years beginning on or after 1 June 2023 and taxes income at 0% up to a threshold set in dirhams and 9% above it. 14 A holding structure earns its place when it simplifies ownership, banking and future expansion, not merely because of a headline rate.

What this means for you

Start from how the business will operate abroad: who signs contracts, where staff sit and which bank accounts the customers will pay. A branch keeps everything in one company, so its results are part of that company's own return. A subsidiary separates risk and local presence but brings the CFC rules. A holding layer adds flexibility for several markets, and a further set of filings.

What to do this month

  • Map where your foreign revenue, staff and contracts will sit over the next two years.
  • Ask your CPA to compare branch, subsidiary and holding outcomes for your ownership, including whether you hold through a US company.
  • Draft intercompany agreements and a pricing method before money moves between entities.
  • List every US information return each option would add, with its due date and owner.

Common mistakes to avoid

  • Forming a foreign company before deciding who will own it.
  • Assuming a foreign entity can be treated as a branch without checking the per se list.
  • Moving assets abroad without considering Form 926.
  • Choosing a holding jurisdiction for its tax rate alone.
