Incorporating a company in the United States, the UK, the UAE, Estonia, Singapore or another jurisdiction does not necessarily mean that the company will only pay tax there.
If the founder lives, works and makes the key decisions from another country, several tax systems can become relevant at the same time.
This creates one of the most common mistakes among online founders:
confusing the country where a company is registered with the country where it is actually tax resident or carrying on taxable business.
Quick answer: an online business may be taxable in the country where it was incorporated, the country from which it is effectively managed, another country where it has a permanent establishment, or in several jurisdictions at once. The founder’s personal tax residence does not automatically determine the company’s residence, but it can become highly relevant when that founder is also the person who actually manages and operates the business.
The right question is therefore not simply:
“Where is my company incorporated?”
It is:
“Where is it incorporated, where is it actually managed, where does the team work, where is the business carried on, and where does it have a taxable presence?”
Five questions that determine where an online business may be taxed
Before comparing corporate tax rates or “business-friendly” countries, five separate questions need to be answered.
| Question | Why it matters |
|---|---|
| Where was the company incorporated? | May determine corporate residence under domestic law and creates local legal and filing obligations. |
| Where are the key decisions actually made? | May affect central management and control, place of effective management or company residence. |
| Where is the business actually carried on? | Can create a permanent establishment or another taxable presence. |
| Where do the founder and team live and work? | Can affect personal residence, payroll, social security, management and permanent establishment. |
| Where are customers, assets, inventory and intellectual property? | Can affect source of income, withholding taxes, VAT, GST, sales tax and other obligations. |
The tax answer comes from combining these layers.
A sustainable international structure needs them to be consistent with one another.
Where a company is incorporated is not always where it is tax resident
The jurisdiction of incorporation matters.
But it is not always the end of the analysis.
Different countries use different corporate residence tests.
Some rely heavily on incorporation.
Others also use concepts such as:
- central management and control;
- place of effective management;
- effective management and control;
- head office or principal management;
- or similar factual tests.
This can create a situation where:
Country A says: “The company is resident here because it was incorporated here.”
Country B says: “The company may also be resident here because this is where it is actually managed.”
That is how dual corporate residence can arise.
What are “central management and control” and “place of effective management”?
The terminology varies between countries, and the concepts are not identical.
But the central question is usually similar:
Where are the company’s most important strategic and commercial decisions actually made?
This is not necessarily the same place as:
- the registered office;
- the registered agent;
- a virtual address;
- the company bank account;
- the accountant;
- the website server;
- or the address printed on invoices.
Tax authorities can look at the reality of management.
Relevant facts may include:
- who makes strategic decisions;
- where that person usually works;
- where major contracts are approved;
- where pricing and investment decisions are made;
- where financing decisions are made;
- who controls the bank accounts;
- where senior management operates;
- where budgets are approved;
- and whether directors genuinely exercise authority or simply approve decisions made elsewhere.
The United Kingdom: central management and control
A UK-incorporated company is generally UK resident, subject to treaty and statutory exceptions.
But UK tax law also uses the long-established central management and control test for foreign-incorporated companies.
HMRC states that central management and control is fundamentally a question of fact and focuses on the highest level of control of the business.
Official guidance: HMRC — company residence and central management and control.
Canada: central management and control
Canada also applies a common-law central management and control test in relevant circumstances.
The Canada Revenue Agency explains that factors such as bank accounts, records or directors’ residence may be relevant but are not necessarily conclusive.
The fundamental issue is where the company’s real central management and control is exercised.
Official guidance: CRA — residency of a corporation.
United Arab Emirates: effective management and control
The UAE provides another useful example.
A foreign-incorporated juridical person can be considered a UAE resident for Corporate Tax purposes where it is effectively managed and controlled in the UAE.
The UAE Federal Tax Authority looks at where key management and commercial decisions necessary for the business as a whole are made in substance.
Official guidance: UAE Federal Tax Authority — effective management and control.
These tests are not identical.
But they demonstrate why the real location of management can matter just as much as the jurisdiction printed on the certificate of incorporation.
What happens if the founder lives in another country?
Another simplification needs to be avoided:
A company does not automatically become tax resident wherever its shareholder happens to live.
Ownership and management are different concepts.
For example, an investor can live in Canada and own shares in a UK business that is genuinely run by an independent UK management team.
That is very different from a one-person online company where the founder:
- lives in Canada;
- owns 100% of the company;
- is its sole director;
- controls the bank accounts;
- negotiates every major contract;
- sets prices;
- manages suppliers;
- and makes every strategic decision from a home office in Canada.
The second scenario creates a much stronger relationship between the founder’s location and the company’s actual management.
The better question
Do not ask only:
“Where does the shareholder live?”
Ask:
“What does the shareholder actually do from that country?”
A passive investor, a board member, a CEO and a solo consultant operating through a foreign company can produce very different tax outcomes.
Company residence and permanent establishment are different issues
A company can remain tax resident in Country A and still have a permanent establishment in Country B.
This distinction is fundamental.
Under treaty frameworks based on the OECD Model, a permanent establishment can arise through a sufficiently fixed place of business through which the company’s business is wholly or partly carried on.
Depending on the relevant treaty and domestic law, permanent establishment issues can also arise through:
- offices;
- branches;
- places of management;
- certain dependent agents;
- people habitually concluding contracts;
- or certain projects and business activities.
If a permanent establishment exists, the second country may be entitled to tax the business profits attributable to that presence.
Simple example
A company is incorporated and tax resident in Country A.
Its founder moves to Country B and begins operating from an office there, hires employees locally and develops a significant part of the business from that location.
Country B does not necessarily need to prove that the entire company became resident there.
A different issue may arise first:
the company may have created a permanent establishment in Country B.
Remote work across borders: the OECD updated its guidance in 2025
This has become especially important for online businesses and distributed teams.
In November 2025, the OECD approved an update to the Model Tax Convention commentary addressing when cross-border remote work from a home office may create a permanent establishment for an employer.
Official source: OECD — 2025 Update to the Model Tax Convention.
Does working from home abroad automatically create a permanent establishment?
No.
The fact that an employee or founder works remotely from another country does not automatically turn that home into the company’s place of business.
The facts and circumstances matter.
Relevant factors include:
- how regularly the location is used;
- how much of the person’s total working time is spent there;
- the role performed from that country;
- whether there is a commercial reason for the person’s presence there;
- and how closely the location is connected to the company’s business.
What does the 50% threshold mean?
The updated OECD commentary uses the percentage of working time spent at the foreign home as one factor in the analysis.
In one of the OECD examples, an employee working from a foreign home for approximately 30% of working time would generally not cause that home to become a place of business of the enterprise in the absence of other relevant circumstances.
Where an individual spends 50% or more of working time there, the analysis becomes more fact-sensitive and a commercial reason for the person’s presence in that country can become particularly important.
For example, the OECD gives a case where a person works 80% of the time from a foreign home and regularly serves customers in that same country; the facts support the existence of a fixed place permanent establishment.
Important: 50% is not a global automatic safe harbour and it is not a new “183-day rule for companies”.
The relevant tax treaty, domestic law and actual facts still need to be reviewed.
What if the remote worker is the founder?
This can be more complex than an ordinary employee case.
A founder may simultaneously be:
- shareholder;
- director;
- CEO;
- salesperson;
- financial decision-maker;
- and the company’s main worker.
The founder’s location can therefore affect several questions at once:
- personal tax residence;
- company residence;
- central management and control;
- place of effective management;
- permanent establishment;
- payroll;
- social security;
- salary taxation;
- and dividends.
This is why a foreign company controlled by a solo founder needs a very different analysis from a multinational company with independent directors and management.
Does it matter where the customers are?
Yes.
But customer location does not answer the whole question.
A common assumption is:
“My clients are outside my country, so my company’s business is also outside my country.”
That conclusion cannot be made universally.
Customer location can matter for:
- source of certain types of income;
- withholding taxes;
- VAT, GST and sales tax;
- digital services rules;
- local registration requirements;
- and, in some situations, permanent establishment analysis.
But it does not replace the need to analyse:
- where management takes place;
- where people work;
- where infrastructure is located;
- and where the actual economic activity occurs.
An online business may sell to customers in 40 countries without becoming tax resident in all 40.
But that does not necessarily mean that it only has tax obligations in its country of incorporation.
Does the location of the bank account matter?
It can matter as part of the overall operational picture.
But a bank account in:
- the United States;
- the United Kingdom;
- Switzerland;
- Singapore;
- or an international fintech;
does not normally determine corporate tax residence by itself.
The same applies to:
- Stripe;
- Wise;
- Mercury;
- PayPal;
- a cloud server;
- a mailing address;
- or a local phone number.
They may be useful operational components.
They are not substitutes for actual management, activity or substance.
What happens if two countries consider the company tax resident?
A company can become dual resident under the domestic laws of two countries.
For example:
- Country A treats the company as resident because it was incorporated there;
- Country B treats it as resident because management and control are exercised there.
The next step is to determine whether a tax treaty exists and how that treaty deals with dual-resident entities.
Not every treaty uses the same tie-breaker
Older treaties may use a direct place of effective management test.
More recent treaty practice influenced by the OECD Model and the Multilateral Instrument may instead require the competent authorities of the two countries to resolve the company’s residence through a mutual agreement procedure.
Factors can include:
- place of effective management;
- place of incorporation;
- and other relevant circumstances.
Never assume that holding a board meeting in one jurisdiction automatically resolves corporate residence.
The actual treaty in force between the countries must be reviewed.
Practical examples: same business, different tax outcomes
The following examples are simplified and intended to explain the framework.
Example 1: U.S. LLC, founder living in the UK
The founder:
- owns a single-member U.S. LLC;
- lives in the UK;
- performs the work from the UK;
- negotiates contracts from the UK;
- and makes all strategic decisions from the UK.
Looking only at the U.S. treatment of the LLC would be incomplete.
The analysis may also need to consider:
- the founder’s UK tax residence;
- how the UK classifies the LLC;
- central management and control;
- the activity carried on in the UK;
- VAT;
- payroll or National Insurance where relevant;
- and any applicable treaty provisions.
For the U.S. side of the analysis, see our guide on U.S. LLC taxation for non-residents.
Example 2: UK Ltd whose founder moves to the UAE
A UK company has historically been run from London.
The sole founder and director moves to Dubai and begins making all key management decisions from the UAE.
The correct analysis is not simply:
“It is a UK Ltd, so nothing else matters.”
Issues to examine may include:
- the UK’s incorporation and residence rules;
- where central management and control actually sits;
- UAE effective management and control rules;
- the UK-UAE tax treaty;
- possible dual residence;
- and whether the company’s operating model has genuinely changed.
Example 3: Canadian founder with a genuinely independent foreign company
A Canadian resident owns shares in a foreign company.
The foreign company has:
- an independent management team;
- its own office;
- local employees;
- directors who actually make strategic decisions;
- its own contracts;
- and genuine business operations abroad.
The Canadian shareholder does not run the daily business and acts mainly as an investor.
This is very different from a foreign company that exists on paper while every important decision is made personally by the shareholder from Canada.
Example 4: founder relocates but keeps the existing company
An entrepreneur owns an established operating company and decides to move to another country.
The founder should not analyse only personal tax residence.
The relocation may also affect:
- where the company is managed;
- whether a new permanent establishment appears;
- whether the company becomes dual resident;
- salary and payroll;
- dividend taxation;
- CFC rules;
- and the relevant tax treaty.
This is why personal relocation and company structure should be reviewed together.
See our international tax residence advisory service.
An online company does not live “on the internet”
Commercially, a digital business can feel location-independent.
Tax systems still look at real people and real activity.
Someone:
- makes decisions;
- writes the software;
- provides the services;
- negotiates contracts;
- controls the money;
- manages staff;
- owns assets;
- and carries on the business from physical locations.
A digital company may not need a factory, but it still has a tax geography.
What is economic substance and why does it matter?
Substance asks a simple question:
Is there a real business behind the jurisdiction we say the company operates from?
Depending on the business and the jurisdiction, relevant factors may include:
- directors;
- employees;
- office space;
- equipment;
- local expenditure;
- contracts;
- decision-making;
- accounting;
- banking;
- suppliers;
- risk assumption;
- and functions performed locally.
This does not mean every international company needs five employees and an expensive office.
Substance should be proportionate to the actual business.
A solo consulting business, SaaS company, holding company and logistics operation do not require the same type of structure.
Corporate income tax is only one layer
Even after company residence has been analysed, several other tax issues remain.
Personal taxation of the founder
The founder may be taxed on:
- salary;
- director fees;
- consulting fees;
- dividends;
- distributions;
- capital gains;
- or income attributed under special anti-deferral rules.
CFC rules
The founder’s country of residence may have Controlled Foreign Company rules.
In some cases, those rules can attribute certain foreign-company income to the owner even before a dividend is paid.
VAT, GST and sales tax
An online company may have indirect tax obligations in countries where it sells goods or services even without being tax resident there.
Digital services are particularly relevant because many jurisdictions have specific registration rules.
Payroll and social security
Working physically from another country can create payroll, employment tax or social security obligations.
Withholding taxes
Cross-border payments can be subject to withholding at source.
Tax treaties may reduce or eliminate some withholding where the relevant requirements are met.
Transfer pricing
Where multiple related companies are involved, transactions may need to follow arm’s-length principles and documentation rules.
Optimising only the headline corporate tax rate can therefore create a structure that fails in several other areas.
So where should you incorporate your online business?
The better question is not:
“Which country has the lowest corporate tax rate?”
It is:
“Which structure is compatible with where I live, where I work, how the business operates, and where I want it to go?”
| Factor | Why it matters |
|---|---|
| Founder’s tax residence | Can affect personal tax, CFC rules, dividends and company management. |
| Business model | Consulting, SaaS, e-commerce and holding structures need different solutions. |
| Management | Where strategic decisions are made can affect corporate residence. |
| Team location | Employees and directors may create payroll or permanent-establishment exposure. |
| Customers | Can affect withholding and indirect taxes. |
| Tax treaties | Can allocate taxing rights and reduce double taxation. |
| Substance | The company needs a structure consistent with its real activity. |
| Banking and payments | The structure must also work operationally. |
| Compliance costs | Accounting, filings, audit and administration can outweigh expected tax savings. |
| Future plans | Relocation, investment, exit or new shareholders can change the optimal structure. |
9 common mistakes when running a foreign company
1. Assuming the company only pays tax where it was incorporated
That may not be true once management, activity and permanent establishments are considered.
2. Treating a virtual office as economic substance
A mailing address can be operationally useful, but it does not prove where a business is really managed.
3. Assuming the bank account determines company residence
Banking is one part of the operating structure, not the corporate residence test.
4. Ignoring the country where the founder lives
This is particularly risky when the founder is also the sole director, CEO and main worker.
5. Confusing corporate residence with permanent establishment
A foreign company can remain resident abroad and still become taxable in another country on part of its profits.
6. Copying another founder’s structure
A structure that works for someone living in Dubai may produce a completely different result for someone living in London, Toronto or Sydney.
7. Believing an online business has no physical location
Digital work is still performed by people from real locations.
8. Looking only at corporate income tax
Personal taxation, CFC, payroll, VAT, GST, sales tax and withholding can be just as important.
9. Incorporating first and designing the tax strategy later
This is one of the most common mistakes.
The company should be a consequence of the strategy, not the starting point.
Checklist: you own a company in one country and live in another
- Where was the company incorporated?
- Where is it resident under its domestic law?
- Where do you actually live?
- Where are you personally tax resident?
- What role do you perform in the company?
- Where are strategic decisions made?
- Who genuinely exercises management authority?
- Where do you physically work?
- Where does your team work?
- Does the company have offices, inventory or other infrastructure?
- Where are major contracts negotiated and approved?
- Where are the customers?
- Which tax treaties apply?
- Could there be a permanent establishment?
- Could the company be dual resident?
- Do CFC rules apply?
- How do you receive money from the company?
- What indirect taxes apply?
- Does the company have appropriate substance?
- Does the structure fit your future relocation and growth plans?
If several of these questions do not have clear answers, choosing a new jurisdiction may not solve the real problem.
The missing piece may be a complete international tax map.
The right structure starts with the founder, not the company
At N30Global we do not begin by recommending a U.S. LLC, UK Ltd, UAE company or another fashionable jurisdiction.
We first analyse:
founder → tax residence → company → activity → team → income → assets → countries → risks → objectives.
Then we determine which legal vehicles actually fit.
A company with an attractive headline corporate tax rate can become unattractive if:
- it is effectively managed from another country;
- it creates a permanent establishment;
- it triggers CFC rules;
- it duplicates compliance;
- it causes banking problems;
- or it does not fit the founder’s personal tax residence.
When several jurisdictions are involved, the answer should not be an isolated company.
It should be a coherent international tax and corporate architecture.
For more complex situations, see our International Tax Tailoring.
Do you own a company in one country but run it from another?
Before changing companies, adding another entity or moving your tax residence, it makes sense to identify exactly which countries may have taxing rights over the business and over you personally.
At N30Global we analyse the complete picture:
- personal tax residence;
- company residence;
- central management and control;
- place of effective management;
- business activity;
- permanent establishments;
- tax treaties;
- income flows;
- and future objectives.
The goal is not to create a company that looks international. It is to build a structure that is coherent, documented and defensible.
Frequently asked questions
Where does an online business pay tax?
There is no universal answer. Relevant factors can include the country of incorporation, corporate tax residence, where the company is effectively managed, where the business is carried on and whether permanent establishments exist in other countries.
Does a company always pay tax where it is registered?
No. Some countries can also treat a foreign-incorporated company as resident where its central management, control or effective management is located.
If I move abroad, does my company automatically move with me for tax purposes?
No. Personal and corporate residence are separate concepts. However, if you are also the person who actually manages and controls the company, your relocation can materially affect the analysis.
Can working from a home office abroad create a permanent establishment?
Yes, in some circumstances, but not automatically. The OECD’s updated 2025 commentary considers factors including how regularly the home is used, the proportion of working time spent there and whether there is a commercial reason for carrying on the company’s business from that location.
Is there a 50% remote-work rule?
The OECD’s 2025 commentary uses 50% of working time as one factor in its home-office examples. It is not a universal tax rule or automatic safe harbour. Domestic law, the relevant treaty and the specific facts must still be reviewed.
What is central management and control?
Broadly, it refers to where the highest-level strategic management and control of a company is actually exercised. The precise test varies by jurisdiction.
What is place of effective management?
It is a related international tax concept that generally focuses on where key management and commercial decisions for the business as a whole are made in substance. The legal definition and application depend on the jurisdiction and treaty involved.
What is a permanent establishment?
It is a taxable business presence of an enterprise in another country. Where one exists, that country may generally tax the business profits attributable to the permanent establishment, subject to domestic law and any applicable treaty.
Can a company be tax resident in two countries?
Yes. This can happen when two countries apply different domestic residence tests. The applicable tax treaty may then provide a mechanism for resolving the dual-residence position.
Does a virtual office create substance?
Not by itself. Substance depends on the company’s actual functions, people, decisions, resources, risks and operations.
Do international customers mean my company is not taxable where I live?
No. Customer location is only one factor. Company residence, management, permanent establishment and the location of the actual business activity may be more important.
Will a U.S. LLC, UK Ltd or UAE company solve the problem?
Not automatically. The legal vehicle needs to fit the founder’s residence, actual business activity, management, substance and the tax rules of all relevant jurisdictions.
Should I change my company when I change tax residence?
Not necessarily. Sometimes an existing company can remain appropriate; in other cases restructuring may be advisable. The best time to analyse this is usually before the relocation, not afterwards.
