Tax Identification Numbers in Dominica: What Foreign Owners Need to Know
A tax ID in Dominica is the Taxpayer Identification Number (TIN) issued by the Inland Revenue Division, the tax administration arm of the Ministry of Finance. It identifies a person or business for income tax, value-added tax, withholding, and customs purposes, and it is assigned only when you register, never automatically. For a foreign owner, the practical question is rarely how to get a TIN and more often whether you need one at all, because the country taxes on a territorial basis and exchanges account data under the OECD Common Reporting Standard.
This article explains when the obligation arises, how the number is structured, where to apply, and how the TIN connects to bank account opening and cross-border reporting. It is most useful to non-resident investors holding or considering an International Business Company, and to the advisers completing self-certification forms on their behalf.
Does Dominica Issue a Tax ID? The TIN and Its Local Context
The country does issue a Tax Identification Number, known locally as both the "TIN" and the "taxpayer number." It is administered by the Inland Revenue Division (IRD) under the Income Tax Act, Chapter 67:01, and serves both tax and customs functions.
Two features matter for anyone based abroad. The number is registration-based, so no TIN exists until you apply for one; and the territorial system means foreign-source income generally falls outside the tax net, which keeps the TIN relevant mainly to those with local income, VAT obligations, or domestic trading activity.
The IRD does not publish detailed TIN information on its own website, a point noted in the OECD's own documentation for the jurisdiction. For format and reporting questions, the authoritative reference sits on the OECD's exchange-of-information portal rather than with the domestic revenue body.

Who Must Obtain a Tax ID in Dominica
Income tax applies to most earnings and profits, including employment income, rents, dividends, pensions, and income arising overseas for residents. Anyone considered resident must file a return with the IRD by 31 March each year, and physical presence of more than 183 days continuously is one route to residency.
A filing exemption applies where income comes entirely from employment and is below EC$30,000. Persons earning from business, rental, royalties, interest, commissions, fees, or annuities are within the charge to tax and should register before they begin.
Businesses face a clear first step: contact the IRD and complete a registration form before commencing operations, after which the office advises whether a licence is needed. A separate VAT registration is triggered once the Comptroller is satisfied that annual gross sales will exceed EC$250,000.
A non-resident owner whose income is entirely foreign-source, operating only through an International Business Company that transacts outside the country, is generally not required to hold a personal local TIN. This reflects the territorial system rather than a confirmed statutory exemption, so confirm your position with the IRD before relying on it.
Format and Structure of the Dominica Tax Identification Number
The TIN runs to a maximum of six digits plus one check digit, with the core taxpayer number being the first six. There is no alphanumeric prefix, letter code, or sector-specific variant in the public record, which keeps the structure simpler than some neighbouring systems.
You will find the number only on documents generated for tax and customs purposes, and it also appears on the driver's licence. Because the domestic site carries no format guidance, the OECD's Dominica TIN sheet is the document to consult for the definitive breakdown.

How and Where to Apply: The Inland Revenue Division Process
Registration is handled by the Inland Revenue Division at High Street, Roseau. The office runs a Tax eFiling system for those already registered, but initial registration is an in-person matter.
The route depends on your existing status:
- If already registered, visit the IRD office, present a national ID, and request TIN verification.
- If not yet registered, submit identification documents with a completed registration form; a TIN is issued after approval.
- For a business, complete the registration form before trading begins, after which the IRD confirms whether a licence applies and which type.
No published processing time or specific fee schedule for TIN issuance was available from an official source. TIN registration in small Caribbean jurisdictions is typically free, though this has not been confirmed for the jurisdiction here, and remote registration guidance for non-residents has not been published.
Documents Required for a Tax ID Application
Individuals are expected to present a national ID card or passport when registering. Companies register by completing the IRD registration form, which the "Starting a Business" page lists as a downloadable PDF.
No official checklist separating resident from non-resident applicants, or companies from individuals, is publicly available. The IRD's Taxpayer Services section and its downloadable business guide are the sources to verify documentary requirements before you travel or instruct an agent.

Tax ID vs Company Registration Number vs Social Security Number
Foreign owners frequently conflate three separate numbers issued by three separate bodies. Incorporating a company does not give you a tax registration, and a tax registration does not cover social security.
| Identifier | Issuing body | Primary use |
|---|---|---|
| Tax ID (TIN) | Inland Revenue Division | Income tax, withholding, customs; max 6 digits + check digit |
| VAT registration number | Inland Revenue Division | Triggered above EC$250,000 gross sales |
| Company Registration Number | Companies Registry, under the Registrar of Companies | Incorporation; confers no tax registration |
| Social Security Number | Dominica Social Security | Employer and employee contributions |
The company number and the TIN live in different systems, and no public source describes a linking mechanism between them. Social security sits apart again; Age Benefit paid by the Dominica Social Security is itself exempt from income tax, which underlines how distinct the two regimes are.
What the Tax ID Is Used For: Filing, Banking, and Self-Certification
The TIN appears on personal returns such as form IT4, on company and partnership returns, and on withholding tax certificates, all of which the IRD publishes on its forms page. Employers also reference it on certificates when deducting tax at source under the Pay As You Earn system.
Banking is where the distinction between a local and a foreign TIN catches people out. Financial institutions in the jurisdiction must collect TIN data to establish tax residency, and a non-resident opening an account will be asked for the TIN of their home country, not a local one.
For self-certification under the Common Reporting Standard, a local TIN is needed only from those who are tax resident in the jurisdiction. Taxpayers with regional income streams should also be aware of the Caribbean Community Double Taxation Agreement Order, 2008.
The Tax ID and CRS Compliance for Non-Resident Owners
The jurisdiction is a confirmed participating member of the OECD's Automatic Exchange of Information framework, and it applies both CRS and FATCA while maintaining tax information exchange agreements with countries including the United States and the United Kingdom. Under CRS, the name, address, TIN, date and place of birth, balance, and income of each reportable person are exchanged automatically each year.
For a non-resident who owns a local entity, the financial institution holding the account collects a self-certification recording the controlling person's home-jurisdiction tax residency and TIN. A local TIN is requested only where the controlling person is also tax resident in the jurisdiction.
The OECD flags the jurisdiction's citizenship and residence by investment schemes as high risk for circumventing CRS reporting. Banks worldwide apply heightened scrutiny to such passport holders, whether or not a local TIN has been obtained.
A FATCA intergovernmental agreement is in place with the United States, under which local institutions report US account data to the IRD for onward transmission to the IRS. The specific IGA model and its effective date were not available in the public record. For the underlying guidance, the IRD maintains an International Tax section covering AEOI, Country-by-Country Reporting, FATCA, and Mutual Agreement Procedure.
Practical Challenges for Foreign Applicants and Advisers
The absence of TIN guidance on the domestic revenue site pushes applicants toward the OECD portal or direct contact with the IRD. Registration is a deliberate step rather than an automatic assignment, which can surprise non-residents who assume a number arrives with incorporation or citizenship.
No online application or verification tool has been confirmed, so in-person attendance in Roseau or a local agent is the practical route for first registration. Advisers should expect overseas banks to scrutinise clients holding investment-migration passports, given the OECD flag, regardless of TIN status.
A subtler friction arises for entities that earn no local income. They may have no obligation to obtain a local TIN, yet foreign banks often expect a TIN for every jurisdiction of claimed tax residency.
The OECD treats a TIN as any unique identifier used to administer tax laws and accepts a "functional equivalent" where no formal number exists. On a self-certification form, this lets an adviser state "TIN not issued" or supply an equivalent where the jurisdiction has issued none.
Conclusion
For most foreign owners operating through a Dominica entity that trades only abroad, no local tax ID is required, and the territorial system is the reason. The number becomes relevant once you earn local income, cross the VAT threshold, employ staff, or otherwise establish tax residency, at which point registration with the Inland Revenue Division is an in-person, document-based step. The recurring point of confusion is the bank form: a foreign bank wants your home-country TIN, and "TIN not issued" is a legitimate entry where the jurisdiction has assigned you none. Confirm your obligation directly with the IRD before assuming either way, particularly if you hold a citizenship-by-investment passport.

Frequently Asked Questions
Generally no. Where an International Business Company transacts solely outside the jurisdiction and earns no local-source income, the territorial system means there is usually no obligation to hold a personal local TIN, though you should confirm your specific position with the IRD.
A financial institution in the jurisdiction collects your home-country TIN for CRS self-certification, not a local one, when you are a non-resident. The local number is requested only if you are also tax resident there.
The TIN runs to a maximum of six digits plus one check digit, with no letter prefix or sector code, and the core taxpayer number is the first six digits. It appears on tax and customs documents and on the driver's licence.
No. The TIN comes from the Inland Revenue Division for tax and customs purposes, while the company registration number is issued separately by the Companies Registry and confers no tax registration on its own.
No online application or verification tool has been publicly confirmed. Initial registration is an in-person matter at the IRD office in Roseau, so non-residents typically attend personally or appoint a local agent.
The OECD flags the jurisdiction's investment-migration schemes as high risk for circumventing CRS reporting. As a result, banks worldwide apply enhanced due diligence to such passport holders, whether or not a local TIN has been issued.
