You run an international business from outside the US, and you’re wondering whether an offshore business structure would serve it better. For the right business, a well-designed structure lowers the tax on profit, removes US payroll tax on your salary, and sets up a clean exit. For the wrong one, it adds cost and reporting without saving anything.
It comes down to three things: where you live, where the company is managed, and the US rules that tax a foreign company’s profit each year. As a US citizen or green card holder, you never step outside those rules.
This guide shows how to tell whether offshore makes sense for your business and how to design a structure that holds up. It compares the numbers for an LLC, an S corp, and an offshore structure in 2026. It also covers substance, reporting, exit planning, and the cases where offshore is the wrong answer.
If you’re not a US citizen or green card holder, skip to our section for non-US founders.
Key takeaways
The US still taxes you: An offshore company changes the rate, timing, and type of US tax, not whether you owe it.
Three questions decide the outcome: Where you live, where the company is managed, and which controlled foreign corporation (CFC) rules apply.
Active profit can be taxed at 12.6%: That’s the 2026 NCTI rate through a US C corp or a Section 962 election, versus up to 37% without either.
An S corp election is a first step, not the finish line: Abroad, its profit gets no FEIE and may be taxed twice.
Your foreign company can pay you efficiently: Its salary is generally outside US payroll tax and with FEIE you can exclude up to $132,900 for 2026.
Incorporation isn’t residence: A zero-tax company run from a high-tax country may be taxed there.
Offshore is sometimes the wrong answer: Compliance costs, US-source income, or thin substance can outweigh the savings.
What is an offshore business structure, and is it legal?
An offshore company cuts your taxes only when three things line up: your residence, the company’s residence, and the anti-deferral rules that apply to you. Get one wrong and the structure can cost more than it saves. Every structure we design at GEA starts with these three questions:
Where are you taxed? US citizens and green card holders are always taxed by the US, wherever they live. Your country of residence may tax you as well.
Where is the company taxed? The country of incorporation is only the starting point. The country you run the business from may treat the company as resident, or as having a taxable presence.
Which CFC rules reach you? Controlled foreign corporation (CFC) rules let a country tax a foreign company’s profits as if the owner earned them directly. For US persons, those rules are Subpart F and NCTI.
The company’s legal form matters far less than these three answers. A company in a zero-tax jurisdiction, run by a US citizen from a high-tax country, can end up paying tax in two places.
Can a US citizen avoid US tax with an offshore company?
No. A US citizen or green card holder can’t use an offshore company to avoid US tax. The US taxes citizens on worldwide income. The CFC rules also tax your share of the company’s profits each year, even if the money stays in the company.
What an offshore structure can change is the rate, the timing, and the type of tax. The legitimate effects are:
A lower rate on business profit: With the right ownership layer, active profit is taxed at an effective 12.6% instead of ordinary rates of up to 37%.
No US payroll tax on salary: Wages from a foreign employer generally fall outside US Social Security and Medicare tax. Your country of residence may charge its own.
The FEIE on your salary: A salary for services performed from abroad may qualify for the Foreign Earned Income Exclusion (FEIE) if you have a foreign tax home and meet the eligibility requirements. The maximum exclusion is $132,900 for 2026.
Living abroad does open up other tools, including the FEIE, foreign tax credits, tax treaties, and totalization agreements. What it doesn’t do is take your company outside the CFC rules.
Where most founders start: switching from an LLC to an S corp
Most US founders abroad first cut their self-employment tax by electing S corp status for their LLC, often on the advice of a US-based tax preparer. The S corp reduces self-employment tax, because only a reasonable salary bears payroll tax. Abroad, though, it has limits that a domestically focused advisor can easily miss:
The FEIE only covers the salary: S corp profit isn’t earned income. It’s taxed at ordinary rates each year, with no exclusion.
The salary still carries US payroll tax: An S corp is a US employer, so its wages are subject to Social Security and Medicare wherever you work. A totalization agreement can move you to the local system instead.
Your residence country may not recognize it: Canada and the UK, for example, generally treat a US S corp as an ordinary company rather than a pass-through. That mismatch can mean tax on the same profit in two countries, with credits that don’t line up.
No deferral: S corp profit is taxed every year, whether or not you take it out.
An S corp is often a sensible first step. An offshore structure can take the saving further, but only if the company’s residence and the CFC rules line up. (We explain CFC rules in a moment.)
Where is your offshore company actually tax resident?
An offshore company is tax resident wherever each country’s law says it is, and that isn’t always where it was incorporated. Many countries treat a foreign company as resident if it’s managed and controlled from their territory. If you run the business day to day from home, your home country may claim it.
Three concepts decide this:
Place of effective management: This is where key management and commercial decisions are actually made. The UK, Spain, Portugal, and Mexico all apply versions of this test.
Permanent establishment: A fixed place of business, or someone who regularly signs contracts, can let a country tax part of the profit. The company can remain resident elsewhere.
The US approach: The US decides corporate residence by place of incorporation. A foreign company doesn’t become a US corporation just because a US citizen owns it.
The US picture has one caveat. Income effectively connected with a US trade or business (ECI) is taxed in the US, no matter who owns the company.
A management warning: A company incorporated in a zero-tax jurisdiction but run from your laptop in Lisbon or Mexico City may be taxed in Portugal or Mexico. Check your residence country’s management rules before you incorporate anywhere.
What makes a foreign company a CFC?
A foreign company is a controlled foreign corporation (CFC) when US shareholders together own more than 50% of its vote or value. A “US shareholder” is a US person who owns at least 10%. A US founder who owns 100% of a foreign company therefore owns a CFC by definition (IRC §957).
Three rules catch people out:
Indirect ownership counts: Shares you hold through other entities, and sometimes shares held by family members, are attributed to you.
Green card holders count too: Permanent residents are US persons for these rules, including while they live abroad.
Reporting applies even with no tax due: A CFC owner files Form 5471 every year, whether or not any tax is owed.
Once a company is a CFC, two regimes decide how much US tax its profits trigger each year: Subpart F and NCTI.
How NCTI and Subpart F tax offshore profits in 2026
Subpart F taxes a CFC’s passive and certain related-party income each year at the owner’s rates. NCTI (net CFC tested income) taxes most of the remaining profit each year. NCTI replaced GILTI on January 1, 2026, under the One Big Beautiful Bill Act (OBBBA).
The 2026 mechanics:
Subpart F income: This is mainly dividends, interest, royalties, and rents. It also covers some sales and services income routed through related parties.
The NCTI rate: A C corporation shareholder deducts 40% of the inclusion under Section 250. The remaining 60% is taxed at 21%, an effective 12.6% before foreign tax credits.
A broader base: The old exemption for a 10% return on tangible business assets (QBAI) is gone. Nearly all active profit is now in the NCTI base.
Foreign tax credits: 90% of the foreign corporate tax paid can offset NCTI. As a rough guide, foreign tax at an effective rate of about 14% or more can often eliminate the US tax on NCTI if you made a Section 962 election. The exact result depends on your company’s tested income and the foreign tax credit limits.
The high-tax exclusion: Income taxed abroad at an effective rate above 18.9% can be excluded by election.
You’ll sometimes read that GILTI or NCTI only affects income from intangible assets. That was never quite accurate, and since QBAI’s repeal it’s plainly wrong. For a service or digital business, nearly all profit is in scope.
Section 962 election or US C corp: how individuals reach the 12.6% tax rate
An individual who owns a CFC directly pays tax on NCTI at ordinary rates of up to 37%, with no Section 250 deduction. There are two ways to reach the corporate rate instead: a Section 962 election, or owning the CFC through a US C corporation.
How the two routes compare:
Section 962 election: You elect each year to be taxed like a corporation on your inclusion (IRC §962). When the company later pays you, the amount above the tax you already paid is taxed as a dividend.
The dividend catch: Those §962 dividends get the lower qualified rates only if the company is in a country with a US tax treaty. Otherwise they’re taxed at ordinary rates.
US C corp holding company: The C corp takes the NCTI inclusion at 12.6%. Dividends it pays you are qualified dividends, taxed at 15% or 20%.
The C corp’s running costs: It files its own federal return (Form 1120), may owe state filings, and needs careful cash management.
The C corp route often works better for founders who pay out profits regularly from a non-treaty jurisdiction. The §962 route can suit a company in a treaty country, or a founder who reinvests most profit.
Both routes can generally bring the US federal tax on qualifying CFC tested income to 12.6% before foreign tax credits (some limitations may apply). That is the tax on the income inclusion, rather than the founder’s total tax cost.
Distributions to the founder can trigger an additional layer of US tax, and foreign and state taxes may also apply.
Can an offshore company eliminate self-employment tax?
A foreign company that employs you can remove US payroll tax on your salary. The tax rate on business profit is only half of the saving. The other half is payroll tax on what you pay yourself, which the FEIE doesn’t reduce. Here structure decides the answer, because the entity that pays you determines whether US payroll tax applies.
Sole proprietor or single-member LLC: Self-employment tax applies to all net earnings: 15.3% up to the 2026 wage base of $184,500, and 2.9% above it.
US S corp: Only the salary bears payroll tax, but it does so wherever you work.
Employed by your foreign company: Wages from a foreign employer generally fall outside US Social Security and Medicare, unless the company opts in through a Section 3121(l) agreement. With the FEIE, that salary can carry no US tax at all.
Living in a totalization country: The US has social security agreements with about 30 countries. You may pay into the local system instead, at a higher or lower rate.
Lower US payroll tax also means fewer US Social Security credits, a trade-off covered below.
LLC vs S corp vs offshore company: a 2026 tax comparison
The same business can owe very different US tax depending on its structure. In this hypothetical, the offshore structure owes about $19,400 less than a single-member LLC when all profit is paid out.
Alex (hypothetical) is a US citizen who runs a web development business abroad. He qualifies for the FEIE, files single, and earns $250,000 a year after expenses. His country of residence doesn’t tax his foreign-source business profit.
Structure 1: Single-member LLC (taxed as a sole proprietor)
Self-employment tax, including Additional Medicare Tax: $29,900
Income tax after the FEIE: $18,600
Total US tax: $48,400
Structure 2: LLC taxed as an S corp, paying Alex a $100,000 salary
Payroll tax on the salary: $15,300
Income tax on $142,350 of pass-through profit: $24,100 (S corp profit isn’t earned income, so the FEIE only covers the salary)
Total US tax: $39,400
Structure 3: US C corp owning a foreign operating company, paying Alex a $132,900 salary
Payroll and income tax on the salary: $0
NCTI tax at the C corp on $117,100 of profit: $14,800
Tax on $102,300 of qualified dividends to Alex: $14,300, including $1,300 of net investment income tax
Total US tax: $29,000, or $14,800 if the profit stays in the company
The net investment income tax applies because excluded foreign income counts toward its $200,000 threshold.
Assumptions: 2026 federal rates, single filer, standard deduction, the Section 199A deduction where available, no state or foreign tax. Figures are rounded, so lines may not add up exactly.
What the comparison leaves out: costs and drawbacks of offshoring
The $19,400 difference is real, but it isn’t the whole decision. Four factors can shrink it or reverse it:
Compliance cost: Structure 3 needs Forms 5471 and 8992, a corporate return, and foreign company fees every year. Those costs come straight off the saving.
Social Security credits: Structures 1 and 2 build US Social Security credits. A foreign salary doesn’t.
Your residence country: Move Alex to Spain or Germany and the local tax on the company or the salary changes the whole comparison.
Substance: The foreign company needs a real business role, and it must hold up under your residence country’s management rules.
Model all four before you compare structures on tax alone.
Economic substance: why shell companies no longer work
An offshore company now needs real substance: people, decisions, and activity where it claims to be based, in proportion to what it does. A shell company, one that exists only on paper, struggles to bank, to claim local exemptions, and to survive a challenge from your residence country.
What has changed:
Economic substance laws: Since 2019, the BVI, Cayman, and other tax-neutral jurisdictions require companies in certain activities to show adequate local presence. Holding, IP, financing, and distribution are among them.
Hong Kong’s FSIE regime: Since 2023, Hong Kong companies in multinational groups keep their exemption on offshore passive income only if they meet substance or similar tests. A company owned by a US holding company counts as part of a group.
UAE corporate tax: A 9% tax applies to profits above AED 375,000. Free zone companies keep 0% on qualifying income only if they meet substance and activity conditions.
Bank due diligence: Banks now ask who runs the company, from where, and why it exists. Weak answers lead to closed accounts.
The OECD’s 15% global minimum tax only applies to groups with revenue of €750 million or more. It rarely affects founder-owned businesses.
Choosing a jurisdiction for a US-owned offshore company
For a US owner, the right jurisdiction is usually the one that fits your operations, banking, and exit plans at the lowest total cost. The lowest headline tax rate matters less, because NCTI collects the difference on untaxed profit anyway.

What US tax forms does an offshore company need?
A US-owned offshore company triggers several US information returns each year, filed by you or your US holding company rather than by the foreign company. The core ones are Form 5471 and Form 8992, plus FBAR and Form 8938 for the accounts. They apply even when no tax is due, and a missing Form 5471 carries a $10,000 penalty per form per year.
The core filings for a US-owned offshore structure:
Form 5471: One for each foreign corporation you own or control.
FBAR (FinCEN Form 114): Required if your foreign accounts exceed $10,000 combined at any point in the year. Company accounts you can sign on count.
Form 8938: For foreign financial assets above set thresholds. For a single filer abroad, that’s over $200,000 at year-end or $300,000 at any time.
Forms 8858, 8865, and 926: These cover foreign disregarded entities, foreign partnerships, and certain transfers of property to a foreign company.
We map every one of these before a structure goes live. The IRS also matches these returns against account data that foreign banks report under FATCA. Our tax preparation firm, Online Taxman, handles the annual filings for many GEA clients.
If you’re already behind: Missed Forms 5471 or FBARs can usually be fixed through formal late-filing or disclosure procedures. The route you choose affects the penalties, so get a clear read on your exposure before you file anything. Strict confidentiality guaranteed.
Holding companies, IP, and transfer pricing
Once you have more than one entity, how money moves between them matters as much as where they sit. Related companies must deal with each other at arm’s-length prices, and intellectual property (IP) should sit where it’s actually developed and managed.
Intellectual property: Transferring existing IP to a foreign corporation can trigger US income recognition under Section 367(d) or other applicable rules. The treatment depends on whether the transaction is a contribution, sale, license, or another arrangement.
Transfer pricing: Fees and royalties between your entities need documented, market-based pricing. See our guide to transfer pricing studies.
Holding layers: A treaty-country holding company can cut withholding tax on dividends, interest, and royalties, but only with real substance.
Planning the exit on day one
The best time to plan how you’ll leave a structure is before you form it. A sale, a wind-down, or a move can trigger tax the operating years never showed.
Selling the shares: Gain on CFC shares can be taxed as a dividend to the extent of earnings not yet taxed in the US (Section 1248). Earnings already taxed under NCTI or Subpart F aren’t taxed again as they move up the chain.
Renouncing citizenship: CFC shares count toward the $2 million net worth test and the exit tax. See our guide to renouncing US citizenship.
Bringing in investors: Investors often expect a specific holding structure, and retrofitting one is costly.
The cost of getting this wrong is almost always higher than the cost of getting it right the first time. Speak with a senior advisor who has designed and unwound offshore structures before.
An offshore structure is the wrong answer when the tax it saves is smaller than the cost and risk it adds. We reach that conclusion with clients more often than people expect. The common cases:
Modest profit: At lower profit levels, annual compliance and company costs can exceed the tax saved.
A high-tax residence country: If your home country taxes the company through management or CFC rules, the US saving can disappear into local tax.
US-source income: Work performed in the US, US real estate, or US operations create US-taxed income regardless of the structure.
No capacity for substance: A company you can’t manage, bank, or document properly adds risk rather than savings.
Social Security matters to you: A foreign salary builds no US Social Security credits.
In these cases, the right US entity, a totalization certificate, or careful use of the FEIE and foreign tax credit often does more. That work sits in our advanced US tax planning practice.
Offshore structuring for non-US founders
If you’re not a US citizen or green card holder, US CFC rules don’t apply to you. Your own country’s rules do, and those usually depend on where you live, not which passport you hold.
Your residence decides: The UK, Germany, Australia, Canada, and many other countries have CFC rules. Some also tax built-in gains on your shares when you leave.
A US LLC isn’t automatically tax-free: Without US-connected income, it usually owes no US federal income tax. It still files Form 5472 each year ($25,000 penalty if missed), and your home country may tax it anyway.
Our formation firm, Entity Inc., forms and maintains US companies for global founders.
Quick answers: offshore business structuring
Is my foreign company a CFC if I own less than 50%?
It can be. A foreign company is a CFC when US shareholders who each own at least 10% together own more than 50%. If you and another US person each own 30%, the company is a CFC. If you own 40% alongside non-US partners, it isn’t, though you may still have US reporting to do.
Can I pay myself a salary from my offshore company and use the FEIE?
Yes, if you work abroad and pass the physical presence or bona fide residence test. For 2026, you can exclude up to $132,900 of that salary. Profit left in the company above your salary is still subject to NCTI.
Is a Hong Kong company tax-free?
No, not automatically. Hong Kong taxes Hong Kong-sourced profit at 8.25% to 16.5%, and offshore profit claims need supporting documentation. For a US owner, any profit Hong Kong doesn’t tax is still subject to NCTI.
Does an offshore company protect my assets?
Only in limited ways. A separate company can ring-fence business liabilities. But transfers made to avoid known creditors can be reversed, and US courts can order a US owner to act. Real asset protection is an estate and trust question, covered by our estate, trust and asset protection practice.
What happens to my offshore company if I move back to the US?
Your company remains a CFC, and the NCTI rules continue to apply. Running it from the US can also create US-taxed business income and state tax exposure. Plan the transition before you move.
I never filed Form 5471 for my company. What should I do?
Don’t file the missing forms on your own without a plan. Established procedures exist for late filings and disclosures, and the right one depends on your facts and whether the lapse was non-willful. Speak with a senior advisor for a confidential review before you act.
Getting the offshore structure right the first time
An offshore business structure saves US tax only when your residence, the company’s residence, and the CFC rules line up. As a US citizen with a CFC, you’re always inside the NCTI regime. The saving comes from the rate, the timing, and payroll tax, and it depends on where you live and how much substance the company has.
That’s why we design the structure around your numbers, not a template. At GEA, the entity, tax, estate, and exit questions are planned together as one integrated strategy through our offshore business structuring practice.
