Guernsey Company Tax Explained: 0% Corporate Tax, No VAT, and What Founders Need to Know

Guernsey is not the secretive tax haven of popular imagination. It is a Crown Dependency with a sophisticated regulatory framework, full commitment to automatic information exchange under the Common Reporting Standard (CRS), and an OECD-compliant tax treaty network. The Bailiwick of Guernsey has been on the OECD white list since 2009 and has signed more than 60 tax information exchange agreements. It is a regulated, transparent jurisdiction that happens to levy 0% corporate income tax on most profits.

That combination — real regulatory credibility alongside a genuinely low-tax environment — is why Guernsey hosts the world's fourth-largest captive insurance market, more than 1,000 authorised investment funds, and a substantial community of founder-led businesses. Understanding how the tax system actually works, including the substance requirements that came into force in 2019, is essential before making any decision about whether Guernsey is the right jurisdiction for your business.

The 0% standard corporate rate: who qualifies and what it covers

Guernsey's standard corporate income tax rate is 0%. This applies to most companies incorporated in Guernsey that are not carrying on financial services business. The 0% rate is not a special regime or an incentive scheme with expiry dates — it is the standard rate, set under the Income Tax (Guernsey) Law 1975 as amended.

Which companies pay 0%

The following types of company are taxed at 0% on their profits:

• Trading companies (retail, wholesale, manufacturing, professional services, technology)
• Property companies holding Guernsey-situs property (with one important exception — see Document Duty below)
• Holding companies that are not caught by the financial services definitions
• E-commerce companies
• Most service companies providing management, consulting, or operational services
• Intellectual property holding structures (subject to substance requirements)

The 0% rate applies to both trading profits and investment income for these companies. There is no minimum tax, no alternative minimum tax, and no surcharge.

What the 0% rate means in practice

A Guernsey-incorporated trading company that earns £500,000 in net profits from providing software services internationally owes £0 in corporate income tax to the States of Guernsey Revenue Service. That is the position under Guernsey law. Whether the ultimate shareholder (if non-resident) owes tax in their country of residence on those profits is a separate question governed by their domestic tax law and any applicable double tax agreements. Guernsey itself charges nothing at the company level.

This is worth being direct about: the 0% rate is genuine. It is not subject to undisclosed conditions, anti-avoidance "carve-backs", or minimum effective tax rules at the company level. Guernsey has deliberately not implemented Pillar Two global minimum tax rules (the OECD's 15% global minimum) for domestic companies, though this remains a developing area and the position may evolve.

The 10% tier: financial services businesses

Financial services companies pay corporate income tax at 10% in Guernsey. This is the "intermediate rate" introduced to address OECD concerns about harmful tax competition in the financial services sector while remaining competitive with other Crown Dependencies.

Who is caught at 10%

The 10% rate applies to companies that derive income from:

• Banking business: deposit-taking, lending, credit activities regulated by the Guernsey Financial Services Commission (GFSC) under the Banking Supervision (Bailiwick of Guernsey) Law 2020
• Fiduciary business: trust companies, corporate service providers, fund administrators regulated under the Fiduciaries (Bailiwick of Guernsey) Law 2020
• Insurance business: insurers and insurance managers regulated under the Insurance Business (Bailiwick of Guernsey) Law 2002, including captive insurance vehicles
• Investment business and fund management: fund operators, investment managers, and discretionary portfolio managers licensed under the Protection of Investors (Bailiwick of Guernsey) Law 2020
• Regulated utilities (Guernsey-situs utilities only): electricity, gas, water supply

Only the income from regulated financial services activity is taxed at 10%. If a financial services company has income streams that are clearly outside the regulated activity, those may be taxed at 0%, though in practice most pure financial services companies have predominantly regulated-activity income.

The 10% rate in context

Even at 10%, Guernsey remains extremely competitive for financial services. A fund manager paying 10% on management fees in Guernsey is paying significantly less than equivalent businesses in London (25% Corporation Tax), Luxembourg (17%), or even Ireland (12.5%). The channel is particularly attractive for captive insurance: Guernsey is the leading European captive domicile, with more than 700 captive insurance entities.

Document Duty: the stamp duty equivalent

Guernsey does not have stamp duty in the UK sense, but it does levy Document Duty — a transaction tax on certain instruments that transfer property or shares.

Property transfers

Document Duty on the transfer of Guernsey real property (freehold and long leasehold) is charged at 0.5% of the consideration or the open market value, whichever is higher. This applies to both residential and commercial property. There is no higher rate for additional properties, no surcharge for non-resident buyers, and no land transaction tax overlay — the rate is a flat 0.5%.

Example: A Guernsey commercial property purchased for £1,200,000 attracts Document Duty of £6,000.

Share transfers

Document Duty at 0.5% also applies to the transfer of shares in Guernsey companies where the company's assets consist substantially of Guernsey real property. Pure trading company shares can generally be transferred without Document Duty.

What does not attract Document Duty

The following do not typically attract Document Duty in Guernsey:

• Transfers of shares in companies whose assets are not substantially Guernsey real property
• Intra-group transfers (subject to conditions)
• Transfers on death (governed by succession law, not Document Duty)
• Intellectual property assignments

For founders whose primary concern is the 0% corporate rate on trading profits, Document Duty is generally not a significant factor unless real property forms a substantial part of the business.

No VAT in Guernsey: a significant competitive advantage

Guernsey has no value added tax, no goods and services tax, and no sales tax. This is one of the most commercially significant aspects of the Guernsey tax regime and is frequently underestimated by founders comparing jurisdictions.

Why there is no VAT

Guernsey is not part of the United Kingdom for VAT purposes, nor is it part of the European Union's VAT area. Guernsey has its own separate customs and fiscal jurisdiction. It is not in the UK Customs Union. There is no customs border between Guernsey and the UK for goods shipped below the import VAT threshold, but Guernsey itself has no domestic consumption tax.

This is a constitutional matter, not a policy choice that could easily change. Guernsey would need to introduce entirely new primary legislation, build a revenue collection infrastructure, and train thousands of businesses to implement VAT from scratch. It is not analogous to a government simply choosing to cut a tax rate. The absence of VAT is structural.

What this means for businesses in Guernsey

A Guernsey company selling professional services to UK clients charges no Guernsey VAT on its invoices. Whether the UK client must account for VAT under the UK reverse charge rules depends on whether the supply is a "B2B" supply and whether the UK client is VAT-registered — but that is a UK compliance matter for the client, not a Guernsey compliance matter for the Guernsey supplier.

For digital services supplied to EU consumers, Guernsey suppliers are not part of the EU One Stop Shop (OSS) regime and do not collect EU VAT at source. The liability for EU VAT on digital services supplied to EU consumers by non-EU businesses potentially falls on the non-EU supplier to register in an EU member state — this is a compliance consideration for Guernsey e-commerce businesses selling to EU consumers, and should be reviewed with a specialist.

The practical upshot for most B2B service companies is that the Guernsey invoice is clean and VAT-free. Administrative burden is low. There are no VAT returns to file, no input tax to reclaim, no partial exemption calculations, and no flat-rate scheme elections to make. This simplicity has real value.

Comparison with UK and Ireland

Jersey introduced a 5% Goods and Services Tax in 2008. Guernsey has never introduced a consumption tax, giving it a different compliance profile from its nearest competitor jurisdiction.

Social insurance contributions: what employers and employees pay

Guernsey operates its own social insurance system (equivalent to National Insurance in the UK) administered under the Social Insurance (Guernsey) Law 1978 and subsequent orders. Contributions fund the old age pension, sickness benefit, unemployment benefit, and other social security payments.

The contribution rates

For the 2026 year of charge, the rates are:

The earnings threshold

Contributions are payable on earnings between two thresholds:

• Lower earnings limit: broadly aligned with the annual personal income tax allowance
• Upper earnings limit (Standard Earnings Limit — SEL): £17,360 for 2026

The Standard Earnings Limit is the maximum amount of earnings on which standard social insurance contributions are due. Earnings above £17,360 attract a reduced "above SEL" contribution rate (currently 2.5% employee / 2.5% employer on earnings between the SEL and a higher earnings limit).

Example: An employee earning £50,000 in Guernsey pays:

• 7.35% on earnings up to £17,360 = £1,276.
• 2.5% on earnings from £17,360 to a higher limit = additional contribution.
• Total employee SI contribution: approximately £1,600-£2,000 depending on the year's exact limits.

The employer pays a matching contribution of 7.35% on the same band, plus their rate above the SEL.

Self-employed contributions

Self-employed individuals pay both the employee and employer components, though at a combined rate, since they are both employer and worker. The self-employed rate structure is slightly different — the Guernsey Revenue Service publishes updated tables annually.

Directors and social insurance

Directors of Guernsey companies who draw a salary are subject to social insurance as employees. Directors who draw only dividends are generally not subject to social insurance on those dividend payments. This mirrors the position in many jurisdictions and creates familiar planning considerations around salary/dividend balance — though in Guernsey the calculus is different from the UK because corporate income tax is 0%, so there is no corporation tax deduction benefit from paying a higher salary.

Personal income tax: 20% flat rate

Guernsey's personal income tax is levied at a flat 20% rate. There are no higher bands, no additional rate, and no investment surcharges. The full rate applies from the first pound above the allowances.

Personal allowance and additional reliefs

For 2026, the personal allowance is £15,500. This is the amount of income an individual can earn free of income tax each year. Additional reliefs and allowances include:

• Married or civil partnership allowance: transferred between spouses if one partner is not using their full allowance
• Age allowance: enhanced allowance for taxpayers over pensionable age
• Mortgage interest relief: available on qualifying Guernsey property mortgages (subject to caps)
• Pension contribution relief: contributions to approved pension schemes are tax-relievable
• Charitable gift relief: donations to approved Guernsey charities
• Childcare relief: for qualifying childcare costs

What is taxable

Guernsey income tax applies to:

• Employment income (salary, bonuses, benefits in kind)
• Self-employment and partnership profits
• Rental income from Guernsey property
• Pension and annuity income
• Investment income (dividends, interest) — where it arises in Guernsey or is remitted to Guernsey by a resident

No capital gains tax

There is no capital gains tax in Guernsey. Gains on the disposal of shares, investment properties, business assets, or other capital assets are not taxed. This is a genuine and material advantage for entrepreneurs who have built equity value in a business over time.

No inheritance tax or wealth tax

Guernsey has no inheritance tax, estate duty, or wealth tax. There is no charge on passing assets to the next generation (above and beyond any Document Duty that may arise on property transfers). This makes Guernsey an attractive jurisdiction for family wealth structures and family investment companies.

Practical tax position for a Guernsey-resident founder

A founder resident in Guernsey running a trading company taxed at 0% can extract profits as dividends from the company. Those dividends are income for the individual and subject to 20% personal income tax. After the £15,500 personal allowance, the effective personal tax rate depends on dividend income levels.

Example: A Guernsey-resident director extracts £80,000 in dividends from their 0% corporate rate company.

• Taxable income after £15,500 allowance: £64,500
• Tax at 20%: £12,900
• Effective total rate on £80,000: 16.1%

Compare with a similar position in the UK: a director extracting £80,000 in dividends after the company has paid 25% Corporation Tax would face a significantly higher combined effective rate, with dividends taxed at 8.75% (basic) or 33.75% (higher rate) after the company has already paid tax.

Substance requirements: the rules that changed everything

The substance requirements are the most important development in Guernsey tax law in the past decade. Any founder or adviser who describes Guernsey as a "zero-tax jurisdiction where you just register a company" without addressing substance is giving incomplete and potentially misleading advice.

Background: the EU blacklist threat and the 2019 legislation

In 2018, the EU Code of Conduct Group put Guernsey on a watch list for potential blacklisting because it believed that Guernsey companies were being used to hold intellectual property or other mobile income-generating assets while having no genuine economic presence in the island. The threat of blacklisting as a non-cooperative jurisdiction would have severely damaged Guernsey's financial services industry.

In response, the States of Guernsey passed the Income Tax (Substance Requirements) (Implementation) Regulations 2018 (the "Substance Regulations"), effective from 1 January 2019. These regulations impose a genuine presence test on certain categories of company.

Which companies must demonstrate substance

The substance requirements apply to "relevant entities" that are tax resident in Guernsey and carry on one of the following "relevant activities":

1. Banking — deposit-taking and lending
2. Insurance — direct insurance and reinsurance
3. Fund management — managing the investments of a collective investment scheme
4. Finance and leasing — providing finance to third parties for interest income
5. Headquarters activities — providing group-level management or decision-making services
6. Shipping — operating a ship used in international transport
7. Holding company activity — a pure equity holding entity that holds equity participations and earns dividends or capital gains from those participations
8. Intellectual property activity — earning income from intellectual property assets
9. Distribution and service centre activity — purchasing from related parties and selling to related parties, or providing services to related parties

If a company's income is derived from one of these nine categories, it must demonstrate substance in Guernsey.

The five substance tests

A relevant entity passes the substance test if it can demonstrate all of the following in Guernsey:

1. Management and direction: the company is directed and managed in Guernsey. The board must hold meetings in Guernsey with appropriate quorum (majority of directors present in Guernsey), the board must make strategic decisions in Guernsey, and adequate board meeting minutes must exist to demonstrate this.

2. Core income-generating activities (CIGA): the activities that generate the company's income must be carried out in Guernsey. What counts as CIGA depends on the relevant activity category. For intellectual property holding, this includes developing, exploiting, maintaining, protecting, and enhancing the IP asset — which is a demanding test.

3. Adequate employees: the company must have an adequate number of qualified employees physically present in Guernsey. The Substance Regulations do not set minimum headcount figures but require adequacy for the scale and nature of the activity.

4. Adequate expenditure: the company must have adequate expenditure incurred in Guernsey. Again, "adequate" is assessed relative to the scale of the activity.

5. Adequate physical presence: the company must have an adequate physical presence in Guernsey. A registered office address alone does not meet this test. For active businesses, this typically means actual office space with employees present.

Outsourcing

Companies may outsource substance-related activities to third-party Guernsey service providers, but the board must retain genuine oversight and control. The outsourced provider must be physically in Guernsey and have the resources to carry out the activities. This enables smaller companies to demonstrate substance through professional services firms rather than hiring their own staff, but it does require a genuine and monitored relationship — not simply a letterbox arrangement with a licensed fiduciary.

Consequences of failing the substance test

If a Guernsey-resident company carrying on a relevant activity fails the substance test, the consequences are serious:

• First failure: the Guernsey Revenue Service issues a compliance notice, and the company is required to provide additional information. A monetary penalty applies.
• Subsequent failures: escalating penalties and, ultimately, the Guernsey Revenue Service will report the company to the revenue authority of the country where the ultimate beneficial owner is resident. The Revenue Service will share the company's financial information with that foreign authority. This transforms a Guernsey structure that was previously private into one actively flagged to the home country tax authority.
• Continued failure: the company risks being struck off or having its licence withdrawn (for regulated entities).

The substance requirements are enforced. They are not a box-ticking exercise.

IP structures: the hardest test

For intellectual property holding companies, the substance test is particularly demanding. A company that merely holds a patent or software copyright and collects royalties without anyone in Guernsey actually working on that IP will fail the CIGA test. The relevant activities must include development, maintenance, enhancement, and exploitation of the IP in Guernsey — by qualified people, physically present, with adequate remuneration.

This has significantly reduced the attraction of Guernsey for "pure" IP holding structures where the IP was developed elsewhere and simply migrated to Guernsey for low-rate exploitation. That model is now high-risk and likely non-compliant.

Holding companies: a lighter touch

Pure equity holding companies (owning shares in subsidiaries) face a lighter substance test. They must demonstrate:

• Appropriate management and compliance with applicable laws
• Adequate people and premises for holding and managing equity participations

This is more achievable without a large Guernsey operation. However, "pure equity holding" is narrowly defined — a holding company that also provides services to its subsidiaries, or that actively manages operations, is likely carrying on "headquarters activities" rather than "holding company activity", which attracts a heavier substance test.

CRS and automatic information exchange: Guernsey is transparent

Guernsey was one of the early adopters of the Common Reporting Standard, the OECD's framework for automatic exchange of financial account information between tax authorities. Guernsey committed to CRS in 2015 and the first automatic exchanges took place in 2017.

What this means in practice

Guernsey financial institutions — banks, investment managers, custodians, and trust companies — automatically report to the Guernsey Revenue Service each year the details of account holders who are tax resident in participating CRS jurisdictions. The Revenue Service then passes that information to the tax authority of the account holder's jurisdiction of tax residence.

If a UK-resident individual has a bank account or holds assets through a Guernsey structure, HMRC will receive information about that account annually, automatically, without having to make a request. This information includes account balances, interest payments, dividend payments, and proceeds from disposals.

This does not mean that having a Guernsey structure is problematic — perfectly lawful structures benefit from Guernsey's 0% corporate rate and the information is simply reported in the normal course. It does mean that the era of "offshore = private = invisible" is definitively over. Any UK resident using a Guernsey structure should assume HMRC has visibility.

FATCA compliance

Guernsey also has a FATCA Intergovernmental Agreement with the United States, requiring Guernsey financial institutions to report US persons' financial information to the IRS (via the Guernsey Revenue Service). Guernsey is fully compliant with both FATCA and CRS reporting obligations.

Banking in Guernsey: what founders need to know

Guernsey has a well-established banking sector with major international banks including NatWest International, Lloyds Bank International, HSBC, Barclays, and a number of private and specialist banks. The GFSC regulates banking under the Banking Supervision (Bailiwick of Guernsey) Law 2020.

Opening a bank account

Opening a corporate bank account in Guernsey requires the same documentary framework as in any regulated jurisdiction: verified identity documents for all directors and beneficial owners, source of wealth information, corporate documents, and a business plan or explanation of the company's activity. Banks conduct risk assessments and can decline accounts. A company with no genuine substance in Guernsey and a structure that looks designed primarily for tax avoidance will face difficulty opening an account with any reputable Guernsey bank.

UK banking access

Guernsey companies do not automatically have access to UK high street banking. A Guernsey-incorporated company is a foreign company from a UK bank's perspective. Opening a UK business account is possible but more demanding — the UK bank will apply its own KYC processes, and foreign-incorporated entities face additional due diligence. Many Guernsey companies bank in Guernsey and use international payment services for UK and global transactions.

This is a practical consideration worth assessing before incorporation: if you need a sterling account with everyday UK banking facilities, a UK-incorporated company is simpler. If your banking needs are international, a Guernsey bank with SWIFT capabilities may serve just as well or better.

Principal company structures available in Guernsey

Guernsey offers several corporate structures under the Companies (Guernsey) Law 2008 (CA 2008) and related legislation.

Standard company limited by shares

The most common structure. Governed by CA 2008. Can be private or public. No requirement for a minimum share capital. The memorandum of incorporation, articles of incorporation, and a registered office in Guernsey are required. At least one director (individual or corporate). A company secretary is not required for private companies (though good practice to appoint one).

Formation timeline: typically 1-5 business days through the Guernsey Registry. The Registry offers a same-day service for an additional fee. Online incorporation is available.

Formation cost: the Guernsey Registry charges £100-£200 for incorporation depending on the service level. Formation agents typically charge £200-£800 for the full service including registered office for the first year.

Protected Cell Company (PCC)

Guernsey developed the Protected Cell Company structure, and it remains one of the island's most distinctive offerings. A PCC is a single legal entity divided into separate "cells", each with its own assets and liabilities that are legally ring-fenced from other cells and from the non-cellular "core" of the company.

PCCs are widely used in:

• Captive insurance (each cell covers a different corporate subsidiary or risk)
• Investment funds (each cell is a separate fund strategy, administered centrally)
• Asset securitisation

The cell protection is backed by statute — creditors of one cell cannot claim against another cell's assets. This makes the PCC extremely efficient for managing multiple similar-but-separate structures without incorporating multiple standalone companies.

Incorporated Cell Company (ICC)

An evolution of the PCC, the Incorporated Cell Company allows individual cells to be separately incorporated, giving each cell its own legal personality. Cells within an ICC can contract in their own name and have their own shareholders.

Limited Partnership (LP)

Guernsey Limited Partnerships are popular for investment fund structures, particularly private equity and real estate. The LP itself is transparent for Guernsey tax purposes — income and gains flow through to the partners. The general partner (often a Guernsey company) has unlimited liability; limited partners have limited liability.

Foundation

Guernsey also permits foundations under the Foundations (Guernsey) Law 2012 — a hybrid between a company and a trust, with no shareholders and a purpose-based governance structure. Useful for holding family wealth, philanthropy, or certain employee benefit structures.

Incorporation and annual filing requirements

Incorporation with the Guernsey Registry

The Guernsey Registry (registry.gg) handles company incorporation. The application requires:

• Application form (completed electronically or on paper)
• Memorandum of incorporation (CA 2008 companies)
• Articles of incorporation (standard form available; can be bespoke)
• Details of directors, officers, and beneficial owners (submitted to the Registry and, for regulated entities, to the GFSC)
• Registered office address in Guernsey
• Beneficial ownership information (registered confidentially with the Guernsey Registry)

Beneficial ownership register

Guernsey maintains a central register of beneficial ownership information. This is not a public register (unlike the UK's Companies House public beneficial ownership register) — beneficial ownership data is held by the Guernsey Registry and accessible by the Guernsey Revenue Service and law enforcement under appropriate legal gateways. Guernsey has committed to aligning with any international movement toward public registers, and this is an area to monitor.

Annual confirmations and financial statements

All Guernsey companies must file an annual confirmation statement (analogous to the UK confirmation statement) with the Guernsey Registry confirming that the company's details are up to date. Private companies are not required to file accounts with the Guernsey Registry publicly, which is a meaningful difference from the UK where full accounts are on the public record at Companies House.

Income tax returns

Guernsey companies must file an annual income tax return with the Guernsey Revenue Service. The return is due within 9 months of the company's accounting year-end. For a company with a 31 December year-end, the return is due by 30 September of the following year. There are no advance payment obligations for corporate income tax (given that most companies pay 0%, the compliance burden is light).

Financial services companies taxed at 10% pay their tax liability by the return filing date.

Employer social insurance filings

Companies with employees must register as employers and file monthly employer social insurance returns and make payments to the Guernsey Revenue Service. The filing deadline is the 15th of the month following the month to which the contribution relates.

PAYE equivalent

Guernsey operates its own income tax instalment deduction (ITD) scheme for employed individuals, broadly equivalent to PAYE in the UK. Employers deduct income tax from employees' salaries and remit to the Revenue Service. Annual employer returns are required.

The Guernsey compliance calendar

The Guernsey tax year is the calendar year (1 January to 31 December) for individuals. Companies can adopt a different accounting year.

Guernsey vs Jersey: the key differences for founders

Jersey and Guernsey are frequently discussed together, but they are separate Crown Dependencies with different legislation, different regulators, and meaningfully different tax regimes.

Why founders choose Guernsey over Jersey

• No GST: for businesses with significant purchases or customer-facing activities, the absence of any consumption tax (vs Jersey's 5% GST) simplifies administration.
• Protected Cell Companies: Guernsey invented the PCC; Jersey has its own equivalent (Incorporated Cell Companies under Jersey law) but Guernsey has a longer track record.
• Captive insurance: Guernsey is the leading European captive domicile by a significant margin.
• Cost: Guernsey is generally modestly less expensive than Jersey for professional services and property, though the difference is not dramatic.

Why founders choose Jersey over Guernsey

• Larger financial services community: Jersey has a larger banking and funds sector and more professional service providers.
• Closer proximity to the UK (for some): Jersey is geographically closer to the English south coast.
• Listed funds: Jersey has historically been the dominant jurisdiction for listed investment funds.

Neither island has a structural tax advantage over the other for standard trading companies — both levy 0% at the company level.

Exempt companies: the historic position

Prior to the introduction of the Substance Regulations in 2019, Guernsey had a formal "exempt company" status that allowed non-Guernsey-resident owned companies to be designated as exempt from Guernsey income tax on certain income — in return for an annual exempt status fee. This regime provided certainty for foreign-owned holding structures.

The exempt company regime has been substantially superseded by the new substance framework. New companies can no longer rely on an exempt designation as an alternative to demonstrating substance. The substance requirements now determine whether a company's income from relevant activities is treated as Guernsey-source income subject to tax (if it fails substance) or whether the 0% rate applies as normal.

Companies incorporated before the substance regulations came into force should verify their position with a Guernsey tax adviser — the transitional provisions and the current ongoing obligations need to be assessed on a case-by-case basis.

Is a Guernsey company right for your business?

The genuine advantages of a Guernsey company are:

• 0% corporate income tax on most profits
• No VAT, no GST
• No capital gains tax
• No inheritance tax
• A respected, stable, OECD-compliant jurisdiction with a strong rule of law
• Flexible company structures (PCC, LP, Foundation)
• English language, English common law
• Good infrastructure and professional services sector

The conditions and constraints are:

• Substance requirements: you must have genuine economic activity in Guernsey for a company carrying on a relevant activity. A shell company with no real presence will fail the substance test.
• CRS reporting: your financial information is automatically shared with your home tax authority. There is no secrecy.
• Banking due diligence: reputable banks require a genuine business rationale and will not open accounts for structures that have no commercial substance.
• Professional services cost: running a Guernsey company properly — with a registered office, local director, accountant, and legal adviser — costs money. Budget for at least £3,000-£10,000 per year in local professional fees for a simple structure, more for regulated entities.
• Physical proximity: if you are building a team, being based on an island 25 miles off the Normandy coast has practical implications for recruitment and logistics.

For the right business — one where the founder or key team is genuinely located in or willing to relocate to Guernsey, or where the business activity can demonstrably be conducted from Guernsey — the combination of 0% corporate rate and no VAT is genuinely compelling.

FAQ

Is Guernsey a tax haven?

Guernsey is frequently described as a tax haven, but this label is contested and largely inaccurate by current international standards. Guernsey is on the OECD white list of cooperative jurisdictions, has signed more than 60 tax information exchange agreements, participates in full automatic information exchange under CRS and FATCA, and has implemented substance requirements that prevent shell companies from claiming low-tax status without genuine economic activity. The 0% corporate tax rate is a sovereign fiscal policy choice, not a secrecy mechanism. Guernsey is better characterised as a low-tax, well-regulated international finance centre.

Does Guernsey have VAT?

No. Guernsey has no VAT, no GST, and no sales tax of any kind. This is a structural feature of Guernsey's separate customs and fiscal jurisdiction, not a temporary exemption. Jersey introduced a 5% Goods and Services Tax in 2008; Guernsey has not followed and there is no current proposal to do so.

Do Guernsey companies have to file public accounts?

No. Private companies in Guernsey are not required to file financial accounts with the Guernsey Registry and those accounts are not public. The Guernsey Revenue Service receives income tax returns, but these are not publicly accessible. This contrasts with the UK, where all limited company accounts are filed at Companies House and publicly searchable.

Can a non-Guernsey resident own a Guernsey company?

Yes. There is no restriction on non-Guernsey residents owning shares in Guernsey companies. However, non-resident beneficial owners must be disclosed to the Guernsey Registry under beneficial ownership rules, and the company must meet its substance requirements if it carries on a relevant activity. The company must also be genuinely managed and directed from Guernsey — not from the country where the non-resident owner lives.

What social insurance do I pay as a Guernsey company director?

If you are an employee-director drawing a salary from your Guernsey company, you pay social insurance at 7.35% as an employee (up to the Standard Earnings Limit of £17,360 for 2026), and the company pays a matching 7.35% as employer. Directors who draw only dividends and no salary do not pay social insurance on those dividends.

How do Guernsey substance requirements affect IP holding?

Intellectual property holding is one of the most demanding relevant activity categories under the Substance Regulations. A company earning royalties from IP must demonstrate that the development, maintenance, enhancement, protection, and exploitation of the IP is genuinely happening in Guernsey — by qualified people, physically present, with adequate expenditure. A company that merely holds the legal title to IP developed elsewhere and collects royalties will fail the substance test and risk having its income treated as taxable in a higher-rate jurisdiction.

Does Guernsey participate in the OECD Pillar Two global minimum tax?

As of mid-2026, Guernsey has not implemented the OECD Pillar Two global minimum corporate tax rules for domestic companies. This means that Guernsey companies remain subject to 0% (or 10%) rather than any 15% global minimum. However, if a Guernsey company is part of a multinational group with annual revenues exceeding €750 million, the group's parent country may apply a "top-up tax" under Pillar Two rules to bring the effective rate on Guernsey profits up to 15%. Founders of smaller businesses below the €750m threshold are generally unaffected by Pillar Two. This is a developing area and professional advice is recommended for any large-group structure.

Can I open a UK bank account for a Guernsey company?

It is possible but more complex than opening a UK account for a UK company. UK banks treat Guernsey companies as foreign entities and apply more demanding due diligence. Many Guernsey companies bank with Guernsey-based banks and use international payment platforms (Wise Business, Revolut Business, Airwallex) for UK and global transactions. If maintaining a UK sterling account is essential to your business model, it is worth testing this with your bank of choice before committing to a Guernsey structure.
