Key Takeaways
- Jersey assigns a tax reference through Revenue Jersey that non-resident owners use for filing and official dealings.
- Registration requires specific documents and information, and the process differs depending on who must obtain the tax ID.
- Your tax ID is distinct from the registered company number and the social security number, each serving a separate purpose.
- Banks and CRS or FATCA self-certification forms rely on the correct TIN, so accuracy matters when dealing from abroad.
Tax Identification in Jersey: What Foreign Owners Need to Know
A tax ID in Jersey is a unique reference that links a person or business to its records at Revenue Jersey, the office that assesses and collects income tax within the Department for Treasury and Resources. The identifier matters to any non-resident who incorporates a company on the island, holds Jersey real estate, or opens a financial account that triggers international reporting.
This article explains what the number looks like, who must obtain one, how registration works, and how the tax reference sits alongside the company number and social security number. It is written for foreign business owners, investors, and their advisers weighing incorporation in or compliance with the jurisdiction.
Does Jersey Issue a Tax Identification Number?
Yes. Individuals receive a 10-digit Tax Identification Number (TIN), while entities are assigned a separate "tax reference number" used for assessing and collecting income tax.
Both are issued by the Comptroller of Revenue, the statutory title for the head of Revenue Jersey. The 10-digit individual number brings the island in line with international tax practice by giving every taxpayer a single, durable identity.
Resident individuals are given a TIN automatically: children born on the island receive one at birth registration, and people who move there are issued one once they successfully register. Entities exempt from income tax, such as charities, may never have been allocated a tax reference number, and a non-resident is given one only where taxable income arises from a source within the jurisdiction.

The Tax Identification Number (TIN) and Its Jersey Format
The format depends on whether you are dealing with a person, a company, or a cross-border reporting requirement. Three distinct numbers operate in parallel, and confusing them is a frequent source of error for foreign owners.
| Identifier | Who holds it | Format | Example |
|---|---|---|---|
| Individual TIN | Individuals with a tax record | 10 digits | (10-digit number) |
| Entity tax reference | Companies, partnerships, other entities | 2 letters + up to 5 digits | CC00000 |
| Social Security number | Individuals (CRS-reported TIN) | 2 letters + 6 digits + 1 letter | JY000000A |
For companies, the tax reference begins with the letter C; partnerships start with D or E, and other entities with E. The individual TIN appears on every piece of correspondence from Revenue Jersey and must be quoted on all payments and communications.
For reporting island residents under the Common Reporting Standard, the relevant identifier is not the 10-digit income tax number but the Social Security number. That number, usually prefixed JY, is individually unique and stays with the holder regardless of personal circumstances.
Who Must Obtain a Jersey Tax ID
Obligations differ sharply by entity type, and the trigger for a non-resident is narrower than for someone living on the island.
Individuals. Anyone with a tax record holds a TIN, assigned at birth registration or upon first registration for tax. A person living locally with a social security number but no tax instalment rate may still need to register so that Revenue Jersey can issue an Income Tax Instalment System (ITIS) rate, and a return becomes due once earnings exceed the personal exemption threshold.
Jersey-incorporated companies. Newly incorporated companies are registered for tax automatically. Every such company must file an annual return, even where there is no tax to pay.
Foreign-incorporated companies. A company formed outside the jurisdiction must notify Revenue Jersey within six months if it becomes resident or earns non-exempt income from island activities. Penalties apply for late registration, and non-resident companies are taxable on Jersey real estate income.
Trusts. Where a trust has resident beneficiaries, you must register it with Revenue Jersey and supply a copy of the trust deed or probate of will.
A non-resident individual or company is issued a tax reference only when it receives taxable income with a Jersey source, including rental income, property development profits, and real estate income.

How to Apply for a Tax Reference with Revenue Jersey
Registration runs through OneGov, the island's online government portal, which is also used for filing returns and accessing records. Once a registration succeeds, Revenue Jersey issues the unique 10-digit TIN.
People who relocate register as living on the island, and that single process covers tax registration, so no separate tax sign-up is required. To file online later, both a OneGov account and the TIN are needed to activate the service.
For companies, the number issued by Revenue Jersey is what activates an online filing account on the secure platform used for the annual corporate return. That return is due by midnight on 30 November of the year following the accounting period; for the 2024 tax year, the deadline falls on 30 November 2025.
Revenue Jersey does not appear to charge a fee for tax registration itself. Any fee you encounter relates to company incorporation at the Companies Registry, which is a separate step.
Documents and Information Required for Registration
A single official checklist for non-resident registration was not available from Revenue Jersey's portal during this research. The requirements below come from the specific scenarios the authority does describe.
- Valid photographic identification, required when a social security number is issued on first arrival
- A copy of the trust deed or probate of will, for trust registration
- Incorporation documents, details of Jersey-source income, and identification of principals would ordinarily be expected for a non-resident entity, though this should be confirmed directly with Revenue Jersey
Financial institutions face an extra prerequisite. Before registering on the Revenue Jersey portal for automatic exchange of information, a financial institution must first obtain a Global Intermediary Identification Number (GIIN) from the US Internal Revenue Service.
Keep your records. Self-employed individuals must retain income records for at least six years, including payslips, receipts for deductible expenses, bank statements, and loan interest certificates, in case Revenue Jersey requests supporting information or opens an enquiry.

How the Jersey Tax ID Differs from the Registered Company Number and Social Security Number
A common misunderstanding is that a company's registration number and its tax reference are the same thing. They are issued by different bodies for different purposes and should never be used interchangeably.
A company receives its registration number from the Jersey Companies Registry, part of the Jersey Financial Services Commission, when it incorporates. The tax reference comes separately from Revenue Jersey when the company registers for tax.
The social security number serves a different function again. It governs contributions, benefits, and access to health practitioners, and it is not used as an identifier for other tax matters, with one exception: it is the number reported for island residents under the Common Reporting Standard.
Using Your Tax ID for Filing and Dealings with Revenue Jersey
The TIN is the thread running through every interaction with the tax authority. It appears on all correspondence and must accompany any payment.
Individuals still file an annual personal return even when an employer deducts tax through ITIS. From the date of arrival, all Jersey income and worldwide income for the tax year must be declared, and certain foreign income may also be reportable depending on residency.
Company returns confirm the entity's details, disclose income and profits, and report relevant distributions or activities, with extra requirements for large companies and those within the economic substance rules. A company taxed at 0% is still expected to file each year.
Missing the deadline is the single biggest trigger for penalties, so diarise the 30 November date well in advance. Self-employed income records, as noted, must be kept for a minimum of six years.
The Tax ID in Banking, CRS and FATCA Self-Certification
When you open an account with an island financial institution as a non-resident, you will be asked to self-certify your jurisdiction or jurisdictions of tax residence and supply the matching TIN for each. This requirement flows from two reporting regimes that the island operates: the Common Reporting Standard and FATCA.
Common Reporting Standard
The jurisdiction is a participating CRS jurisdiction and exchanges financial account information automatically with more than 100 partners each year. It signed a Competent Authority Agreement on 29 October 2014 as an early adopter, and the domestic framework sits in the Taxation (Implementation) (International Tax Compliance) (Common Reporting Standard) (Jersey) Regulations 2015.
Financial institutions collect account holder name, address, jurisdiction of tax residence, TIN, balance, and annual income, then report to the Comptroller of Taxes, who forwards the data to the relevant foreign authority by 30 June. For a resident individual, the reported TIN is the JY-prefixed social security number; a non-resident reports the TIN of their home country.
CRS v2.0 came into force on 1 January 2026, strengthening transparency and aligning with the Crypto-Asset Reporting Framework, while reporting for 2025 remained under the original standard. Structures designed to avoid CRS reporting must be disclosed within 30 days under Mandatory Disclosure Rules enacted in September 2020.
FATCA
The jurisdiction operates as a Model 1 IGA territory under an agreement with the United States signed on 13 December 2013 and adopted domestically on 18 June 2014, with first reporting in 2015. Financial institutions report US account information to the island's government rather than directly to the IRS, and the 30% withholding tax applies only in cases of unresolved significant non-compliance.
A parallel agreement with the United Kingdom was signed on 22 October 2013. The FATCA return deadline, like the CRS one, is 30 June each year.
The island has also signed tax information exchange agreements with 38 countries and continues to negotiate double tax agreements.
Common Pitfalls and Practical Considerations for Non-Residents
The mistakes that catch foreign owners tend to cluster around timing, scope, and which number to quote.
- The six-month window for a foreign company with a taxable presence is firm, and late registration carries penalties.
- A 0% tax rate does not remove the filing duty; every Jersey-incorporated company must submit a return.
- In CRS self-certification, a resident individual reports the social security number, not the 10-digit income tax TIN; a non-resident reports the home-country TIN.
- Financial institutions need a GIIN from the US IRS before they can register for automatic exchange of information, and a nil CRS return is still mandatory.
- Not every registered entity holds a tax reference; charities and other exempt bodies may never have been issued one.
Two further points shape compliance planning. Economic substance legislation has applied to accounting periods beginning on or after 1 January 2019 for resident companies carrying on relevant activities, and from 1 January 2026 crypto-asset accounts fall within reporting scope through CARF.
Conclusion
The island runs a clear, two-track system: a 10-digit TIN for individuals and a lettered tax reference for entities, both issued by Revenue Jersey and kept distinct from the company registration number and the social security number. For a foreign owner, the practical questions are narrow but consequential, namely whether Jersey-source income or a taxable presence triggers registration, and how to report the correct identifier when banks ask for self-certification. Filing duties survive even a 0% rate, and deadlines drive penalties, so the safest course is to confirm your status early and keep records for at least six years. Where the position is uncertain, direct confirmation from Revenue Jersey or a qualified adviser is the reliable route.
