Jersey Tax Identification Number (TIN) Guide

Jersey is a self-governing Crown dependency in the Channel Islands. It operates an independent tax system entirely separate from both the United Kingdom and the European Union — meaning UK VAT registration, EU VAT OSS registration, and UK National Insurance numbers carry no automatic recognition in Jersey. This guide covers every tax identifier issued in Jersey: the social security number for individuals, the tax reference number for entities, and the compliance obligations tied to each.

Social Security Number​

Jersey does not issue a Tax Identification Number (TIN) for individuals in the traditional sense. For Common Reporting Standard (CRS) and FATCA reporting purposes, the social security number serves as the de facto individual TIN. Social security numbers are individually unique and are not changed due to personal circumstances such as marriage or name change.

The Social Security Department issues numbers at birth for Jersey-born residents, or upon first arrival in Jersey for inward migrants presenting valid photographic identification. Numbers are primarily used for social security contributions and benefits, and are also required when registering with a health practitioner. They are not currently used as identifiers for any other tax purpose within Jersey's domestic tax system.

Format: Two letters — almost always JY — followed by six digits and a check letter of A, B, C, or D. Example: JY 123456 A.

Tax Reference Number​

For entities, the TIN is the tax reference number, issued by the Comptroller of Taxes within Jersey's Department of Treasury and Resources. This number is used to assess and collect income tax. Revenue Jersey also uses it as the CRS/FATCA identifier for entities — current issuances are 10-digit numbers, but entities issued under the older scheme continue to use their original two-letter-plus-digits format.

Entities exempt from income tax — such as registered charities — may not hold a tax reference number at all. Non-resident companies and individuals are issued a tax reference number only if they receive taxable income from a Jersey source. Receiving Jersey-source income without yet holding a reference number does not suspend the filing obligation: the duty to file a return arises the moment Jersey-source income is received.

Format: Two letters followed by up to five digits. Example: CC00000.

  • Tax reference numbers for companies begin with the letter C.
  • Numbers for partnerships begin with D or E.
  • Numbers for other entities begin with E.

For a comparison with the similar but distinct formats used in neighbouring jurisdictions, see the Guernsey TIN guide and the Isle of Man TIN guide.

Jersey and GST​

Jersey levies Goods and Services Tax (GST) at 5%. Jersey is outside the UK VAT system and the EU VAT area entirely, so no UK or EU VAT registration satisfies a Jersey GST obligation. Since 1 July 2023, overseas retailers dispatching goods to Jersey consumers from outside the island must register for Jersey GST once annual sales to Jersey non-business customers reach or are expected to reach £300,000. Online marketplaces facilitating such sales are treated as the deemed supplier and bear the registration obligation in place of the underlying merchant. Purely digital services supplied to Jersey-registered businesses remain outside scope via the reverse-charge mechanism; digital services to Jersey consumers by non-residents follow different rules.

To register for Jersey GST, an overseas business must first obtain a Jersey TIN from Revenue Jersey. For a broader comparison of GST and VAT registration thresholds across jurisdictions, see the worldwide VAT registration thresholds guide and the country VAT name directory.

Jersey and the Common Reporting Standard​

Jersey is a fully participating CRS jurisdiction and automatically exchanges financial account information with more than 100 partner jurisdictions each year. Jersey financial institutions collect account holder name, address, jurisdiction of tax residence, TIN (the 10-digit Revenue Jersey number, or social security number for individuals), account balance, and annual income or proceeds. The Comptroller of Taxes forwards this to the relevant foreign tax authority by 30 June each year.

From 1 January 2026, the upgraded CRS 2.0 standard extends the reporting framework to crypto-asset accounts via the Crypto-Asset Reporting Framework (CARF). Arrangements engineered to circumvent CRS reporting must be disclosed to Revenue Jersey within 30 days under the Mandatory Disclosure Rules enacted in September 2020.

Economic Substance Requirements​

Jersey companies carrying on "relevant activities" — including holding company business, finance and leasing, intellectual property, fund management, shipping, headquarters, and distribution and service centre activities — must satisfy the Economic Substance Test under the Taxation (Companies – Economic Substance) (Jersey) Law 2019 in addition to their standard filing obligations. Substance is assessed per financial period and requires that: the board of directors meets and makes decisions in Jersey with a quorum physically present; Core Income Generating Activities are performed within Jersey; and the company has adequate employees and expenditure on the island.

Failure carries a penalty of up to £10,000 for the first period of non-compliance, rising to £100,000 for a repeat failure in the following financial period. Persistent failure can result in the company being struck off the Companies Register. Revenue Jersey also reports non-compliant entities to the tax authorities of the jurisdictions where the beneficial owners are resident.

Frequently Asked Questions​

Does Jersey's 0% corporate tax rate mean my company has no compliance obligations?​

No — this is the most common and costly misconception. The zero-ten regime sets the general corporate tax rate at 0%, but companies carrying on relevant activities (holding, finance, intellectual property, shipping, fund management, and others) must still satisfy the Economic Substance Test each financial period. Failure in the first period carries a penalty of up to £10,000; failure in the following period raises this to £100,000; persistent non-compliance can result in strike-off from the Companies Register. Revenue Jersey also notifies the tax authorities of beneficial owners' home jurisdictions when a company fails. [1] [2]

I sell goods online to Jersey consumers from overseas. When must I register for Jersey GST?​

Any overseas retailer or marketplace dispatching goods from outside Jersey to non-business Jersey consumers must register for Jersey GST (5%) once annual turnover from those sales reaches or is expected to reach £300,000 in a rolling 12-month period. Liability starts from the moment the threshold is breached — not from the date of registration — so failure to register promptly creates a liability for GST on already-completed sales with no ability to retrospectively charge customers. Facilitating marketplaces are treated as the deemed supplier and hold the registration obligation in place of the underlying seller. [3] [4]

My Jersey bank is asking for my TIN for CRS reporting. What is reported, and to which countries?​

Jersey financial institutions are required by law to collect your TIN (the 10-digit Revenue Jersey number for entities, or your social security number if you are an individual), alongside account balance, annual income, and tax residency jurisdiction. The Comptroller of Taxes forwards this data to more than 100 partner jurisdictions by 30 June each year. From 1 January 2026, crypto-asset accounts also fall within scope under the Crypto-Asset Reporting Framework (CARF) introduced through CRS 2.0. Structures deliberately arranged to circumvent CRS reporting must be disclosed to Revenue Jersey within 30 days of implementation under the Mandatory Disclosure Rules. [5] [6]

Jersey is outside the UK and EU — can a non-resident company receive Jersey rental income without registering for Jersey income tax?​

No. Jersey exercises independent taxing rights over Jersey-source income regardless of where the recipient is incorporated or resident. Non-resident companies receiving Jersey rental income or property development profits are assessed to Jersey income tax at 20% — the same rate as applies to Jersey-resident individuals on property income. The obligation to file a Jersey tax return arises the moment Jersey-source income is received; the absence of a tax reference number at that point is not a defence against late-filing penalties. Separately, goods imported into Jersey from the UK or EU after Brexit are subject to Jersey Customs duties and GST on importation; no mutual recognition of VAT registration exists between Jersey and either the UK or EU. [7] [8]

What beneficial ownership information must a Jersey entity disclose to the JFSC, and is the register public?​

Jersey entities registered with the Jersey Financial Services Commission must maintain accurate beneficial ownership records and report to the JFSC's central register. The required information covers every individual who ultimately owns or controls more than 25% of the entity, or who otherwise exercises control — including full name, date of birth, nationality, and residential address. Any change must be notified to the JFSC within 21 days; failure without reasonable excuse is a criminal offence. Providing false or misleading information to the JFSC carries a maximum sentence of seven years' imprisonment. As of April 2026, the register is not publicly accessible — access is limited to law enforcement, regulators, and regulated financial institutions conducting customer due-diligence checks. A further consultation on widening access is ongoing. [9] [10]
