Setting up a local company is often the natural next step for Americans building a business overseas. A UK limited company, a German GmbH, a Singapore Pte Ltd or a UAE free zone company can open doors to local clients, banking and investors.
What many founders do not realise is that incorporating abroad creates a second set of obligations back home.
From the first year, the IRS expects US tax reporting for American-owned foreign companies, and several of the forms involved carry automatic penalties even when no US tax is owed. Local accountants rarely flag these rules, because they sit outside the local system.
Why a foreign company matters to the IRS
The United States taxes its citizens and green card holders on worldwide income, wherever they live. That reach extends to companies they form, own or manage abroad.
A company can be fully compliant with local law and still create US filing duties for its American founder, shareholders, directors and officers. The time to plan for this is before incorporation, when structural choices are still easy to make.
Decision one: what kind of entity are you forming?
Not every foreign entity is treated as a corporation for US purposes. Some foreign company types are automatically corporations. Others can be classified as a partnership or as a disregarded entity by filing an entity classification election on Form 8832.
The choice drives which US forms apply:
- Foreign corporation: Form 5471 each year.
- Foreign partnership: Form 8865.
- Single-owner disregarded entity: Form 8858, with the business income reported directly on the owner’s personal return.
Each route has different tax consequences. A disregarded entity can simplify US reporting and allow local tax to be credited directly, while a corporation can defer some income but brings more complex rules. The election generally needs to be made within 75 days of the effective date, so it belongs in the incorporation plan, not the first tax return.
Form 5471 starts on day one
Forming a foreign corporation and taking 10% or more of its shares counts as an acquisition of stock for US purposes. That usually triggers Form 5471 for the formation year.
The penalty for a missing or incomplete Form 5471 starts at $10,000 per form, per year. The IRS can also keep the founder’s entire US return open to assessment until the form is filed. Founders should understand the full Form 5471 filing requirements before the company is registered.
Most founder-owned companies are CFCs
When US shareholders who each own at least 10% together hold more than 50% of a foreign company, it is a controlled foreign corporation. A solo American founder who owns 100% of their company meets this test immediately.
CFC status means some company profits can be taxed in the US each year, even when the money stays in the business. Two regimes drive this. Subpart F targets passive and certain related-party income. The regime formerly known as GILTI, renamed net CFC tested income under the 2025 tax law changes, reaches most other active business profits.
Local tax rates change the picture
The impact of the CFC rules depends heavily on where the company is formed. Income taxed locally at more than 18.9% can qualify for the high-tax exception, which can remove much of the current US tax.
Companies in higher-tax countries such as Germany, France, Japan or the UK often qualify. Companies in lower-tax locations, including Singapore, Hong Kong, Ireland and the UAE, often do not. For founders choosing between locations, this can be as important as local tax rates themselves.
Paying yourself: salary or dividends
How a founder takes money out of the company affects both tax systems. Salary is earned income and may qualify for the Foreign Earned Income Exclusion or Foreign Tax Credit. Dividends do not qualify for the exclusion, though dividends from companies in treaty countries can receive lower US rates.
A Section 962 election, which lets an individual be taxed like a US corporation on CFC income, is another option worth modelling. The right mix depends on local tax, US tax and the founder’s long-term plans for the business.
Bank accounts and signature authority
A founder with signature authority over the company’s bank accounts usually needs to report those accounts on an FBAR when combined foreign balances exceed $10,000. This applies even though the money belongs to the company.
A pre-incorporation checklist
- Decide how the entity should be classified for US purposes, and whether an election is needed.
- Model local corporate tax against the 18.9% high-tax exception threshold.
- Plan the salary and dividend mix under both tax systems.
- Diary Form 5471, 8865 or 8858 for the formation year.
- Add company bank accounts to your FBAR reporting.
- Keep records of share capital, ownership and earnings from day one.
Bringing in a US specialist early
Local accountants handle local registration, statutory accounts and corporate tax. US international tax reporting is a separate specialty, and it is far cheaper to get right at formation than to fix years later.
Universal Tax Professionals, a CPA-led US expat tax firm founded in 2013, works with American founders on entity classification, Form 5471 and CFC planning in more than 150 countries. Each client works with a dedicated accountant from the first year of the business onward.
