Offshore Company: What It Does and Does Not Do for Tax

What an offshore company is

An offshore company is incorporated in a jurisdiction where its owner does not live and where it does no business with local customers. Most of the market is one of 2 kinds. The zero-tax kind: section 242 of the BVI Business Companies Act exempts a BVI company, every dividend it pays and every gain on its shares from all of the Income Tax Ordinance.

The territorial kind taxes only local income. Seychelles taxes companies on income from activities conducted, goods situated or rights used in Seychelles and treats income from business abroad as non-taxable (Seychelles Revenue Commission), so a Seychelles International Business Company that earns nothing there owes no business tax and files no business tax return (SRC IBC FAQ).

Offshore companies legally hold joint ventures, funds, ships and the shares of trading groups. The case tax authorities look for is narrower: a one-person company that sells its owner's own work and is run from the owner's laptop.

Why 0% in the company's country is not your tax bill

The registry's rate is the first layer only. Then 3 questions decide what you pay on top, and any one of them can replace the zero with your home country's rate.

1. Where you live. Your country of residence may tax the company's profit in your hands.
2. Where the company is run. A company managed from your home can be resident in your home country.
3. Where the work is done. Work done in a country can give the company a taxable presence there.

Test 1: your country's controlled foreign company rules

The first test runs through your tax residency: the country that counts you as resident decides whether the company's profit is treated as yours. Its CFC rules for individuals can add a low-taxed foreign company's profit to your income in the year it is earned, paid out or not. Spain (LIRPF article 91), Portugal (CIRS article 20), Italy (TUIR article 167, moving to a new income tax code on January 1, 2027 under Legislative Decree 117 of 2026) and Brazil (Law 14.754 of 2023) have such a rule. The UK has no CFC charge on individuals but can reach the income through its transfer of assets abroad rules, and Paraguay taxes individuals only on Paraguayan-source income.

Own the offshore company through an EU company and the Anti-Tax Avoidance Directive applies instead: since January 1, 2019 every member state has had to tax the owner company on a foreign company it controls by more than 50%, counting associated enterprises, that pays less than half the tax it would pay at home, on either its undistributed passive income or its income from non-genuine arrangements. The income it reaches also includes that of invoicing companies that buy from and sell to associated companies while adding little value, so an offshore company that resells your other company's services falls under the directive and the transfer pricing rules at once.

US citizens are taxed on worldwide income from all sources wherever they live (IRS), and a US shareholder of a controlled foreign corporation includes its global intangible low-taxed income (GILTI) in income every year under section 951A, whether or not the company pays a dividend (IRS Form 8992). The company also goes on Form 5471, which certain US officers, directors and shareholders of foreign corporations must file (IRS).

Test 2: where the company is managed

Many tax systems also make a company resident where it is run, whatever its certificate says. HMRC states the UK rule from case law: a company incorporated abroad is UK resident if its central management and control is in the UK, the highest level of control is what counts, and it can be exercised by the board or by some other person (HMRC INTM120060).

Other countries use the place of effective management: Croatia treats a foreign company whose effective management and supervision is in Croatia as resident in Croatia for profit tax, and Georgia treats an enterprise as Georgian when its place of management is in Georgia.

For a one-person company the highest level of control is you. If you sign the contracts and approve the payments from your apartment, the company is managed where the apartment is. A nominee director on the register does not change that while you still make the decisions.

Test 3: where the work is done

A company that is not resident in your country can still owe tax there through a permanent establishment, a taxable presence created by business carried on there. Estonia's Tax and Customs Board says so about its own companies: one managed from abroad by an e-resident will probably have a permanent establishment abroad, and income tax must be paid on its profit in that country (EMTA). The same logic applies to a BVI or UAE company run from Lisbon or Berlin.

David's note

I start every company question with where the owner will live for the next 2 years, not with the registry. If you are resident in a country with CFC rules for individuals and run the company yourself, I would not form an offshore company to save tax: it adds a second set of filings and a harder bank account, and the profit is taxed at home anyway. The saving is in the residence decision, and the company follows it.

Economic substance, the EU blacklist and the FATF grey list

Offshore centers such as the BVI and Cayman have economic substance laws, but they reach only companies carrying on 1 of 9 relevant activities, among them holding, intellectual property and distribution and service center business (BVI Economic Substance Act, section 6). A company that sells your work to unrelated clients carries on none of them; one that bills your own companies for services is a service center business and has to show management, staff and premises where it is registered.

What a one-person company does feel is the list status of the place it is registered in. On October 9, 2026 the EU Council's list of non-cooperative jurisdictions named 8, among them Anguilla, the Turks and Caicos Islands and Vanuatu for offshore structures that attract profits without real economic substance (Council conclusions).

The same update kept the BVI on the Annex II watch list. Listing changes how EU countries treat payments to a company and how banks onboard it, so the EU and FATF status of each low-tax and zero-tax jurisdiction matters as much as its rate. BVI companies carry both marks: the BVI is on the FATF list of jurisdictions under increased monitoring as of the June 2026 statement (FATF).

Offshore company bank accounts and CRS reporting

Under the Common Reporting Standard, a bank has to work out whether a company account holder is a passive entity with controlling persons who are reportable, and if it is, the account is reportable with you named as the person behind it (HMRC IEIM403480).

A company is an active entity when less than 50% of its gross income is passive income and less than 50% of its assets produce it, or when it fits another listed category, such as a holding company whose subsidiaries run non-financial businesses or a start-up in its first 24 months (HMRC IEIM404040). Dividends, interest, rents and royalties are passive income (HMRC IEIM404020), so a company that mainly holds portfolio investments is passive.

When an offshore company does lower your tax

An offshore company lowers the bill only when your country of residence leaves its profit alone, because where you are tax resident decides most of your digital nomad taxes. It is a legal way to pay less tax in 4 cases:

• Your country does not reach it. You are resident where there is no CFC charge on individuals and no tax on foreign dividends, and you have checked whether it treats a company you run from there as resident.
• The company has real substance. It has directors who decide, staff and premises where it is registered, which pays only when the profit is large enough to cover them.
• It holds rather than works. A neutral vehicle for partners in several countries, a fund or an asset, with each owner taxed at home on what reaches them.
• You report it at home. Every holding and account sits in your return, so a bank report finds nothing new.

It is the wrong tool when you live in a country with a CFC rule for individuals and own the company personally, when you run it alone from where you live, when you need a mainstream bank account or card processing in the company's name, or when the plan depends on nobody finding out.

Offshore company formation: steps and costs

You do not file the incorporation yourself. In the BVI the memorandum and articles are signed and filed by the proposed registered agent as incorporator (section 6 of the BVI Business Companies Act), and in Seychelles the founder has to approach an International Corporate Service Provider licensed by the Financial Services Authority, which registers the company.

On top of the registry fee come the registered agent, annual filings, accounts and, in Hong Kong, an audit, plus the adviser at home who reports the company. Formation agents differ mostly in what they bundle, so comparing formation services on the second-year renewal rather than the first-year offer shows the real cost. Published prices show the spread: Seychelles formation services charge $850 to about $1,270 for the first year and $850 to $1,200 for each renewal, on government fees of $130 and $140.

Money then has to reach you. Whether it comes out as salary, director's fees or dividends, your country of residence taxes it at its own rates, which makes salary vs dividends a question for your home tax code rather than the company's.

Offshore company, holding company or onshore company

The legitimate offshore uses are mostly about ownership. A holding company that owns shares in operating companies usually sits better in a country with a participation exemption and tax treaties than in a zero-tax registry, because a low-taxed company whose income is dividends and gains on shares is what CFC rules target.

For a founder selling services, the usual alternatives are an onshore company in a low-tax country with treaties, or a US LLC, which owes no US tax when its foreign owner has no US trade or business and is often taxed at home as the owner's own income. How your country classifies an LLC or a limited company decides that, and which of the 2 is simpler.
