Key Takeaways
- Bermuda does not issue a conventional tax identification number, so companies rely on other identifiers received at formation.
- Because there is no income tax, the Registrar of Companies number serves a different purpose than a true tax ID.
- Foreign owners completing CRS and FATCA forms can address the missing TIN using the registration numbers Bermuda actually provides.
- Payroll tax registration creates employer identifiers that often substitute when treaty or withholding forms demand a TIN.
Does Bermuda Have a Tax Identification Number? The Honest Answer
Bermuda does not issue Tax Identification Numbers, and it does not issue any equivalent identifier for tax purposes. This is the settled position confirmed to the OECD, and it follows directly from the fact that the jurisdiction levies no corporate income tax. For a foreign owner, the practical effect is straightforward: a company you incorporate in Bermuda will never receive a "Tax ID" in the sense banks, withholding agents, and treaty forms expect.
That single fact shapes everything else in this article. We explain which numbers a Bermuda company does receive, how those numbers relate (and fail to relate) to international definitions of a TIN, and what to do when a form demands a number that does not exist. The IRS no-foreign-TIN list names Bermuda directly, which makes the absence official rather than an oversight.
This is most relevant to non-resident owners completing FATCA or CRS self-certifications, bank onboarding forms, or withholding documents for a Bermuda-incorporated entity.
Why a No-Income-Tax Jurisdiction Affects How Tax IDs Work
A Tax Identification Number exists so a tax authority can track income, match returns, and enforce assessments. Where there is no income or profits tax to assess against companies or residents, the administrative reason for issuing such a number disappears.
Bermuda's tax system rests on a payroll tax paid by employers and on land taxes, not on corporate or personal income. Because there are no income returns to process, the engine that drives TIN issuance in most countries simply does not run here.
International reporting frameworks anticipated this. Both FATCA and the OECD Common Reporting Standard require financial institutions to collect a TIN or functional equivalent, yet both build in exceptions for account holders resident in jurisdictions that issue none.

Identifying Numbers a Bermuda Company Actually Receives on Formation
Your company will receive identifiers, just not fiscal ones. The Registrar of Companies assigns a Company Registration Number on incorporation, and the same office issues a certificate of incorporation once registration is approved.
Formation is quick. Registration of a new company usually completes in under a week, and the Registrar administers the process under the Companies Act 1981.
The numbers in circulation serve different functions and are issued by different bodies. The table below sets out what a Bermuda business may hold and what each number is for.
| Identifier | Issuing body | Purpose | Is it a TIN? |
|---|---|---|---|
| Company Registration Number | Registrar of Companies | Administrative company identifier | No |
| Entity Registration Number | Registrar of Companies | Administrative entity identifier | No |
| Payroll Tax Number | Office of the Tax Commissioner | Employer payroll tax tracking | No |
| GIIN | IRS (FATCA) | FATCA registration | No |
The structure your business takes determines which statute governs it. Limited liability companies are formed under the Limited Liability Company Act 2016, while partnerships may be registered under the Partnership Act 1902, the Limited Partnership Act 1883, the Exempted Partnerships Act 1992, or the Overseas Partnerships Act 1995.
The Registrar of Companies Number Versus a Tax ID
The Company Registration Number you receive is an administrative identifier, nothing more. It records the existence of the entity on the public register; it does not link to any tax assessment.
Treating that number as a TIN under OECD or IRS definitions is not legally correct, because no TIN regime exists to give it that status. The Bermuda TIN page maintained by the OECD states plainly that no TINs are issued.
Some countries that issue no TIN allow other numbers, such as a company registration number, to stand in for entities. Whether a particular bank or counterparty accepts the Bermuda registration number in that role is a matter of that institution's internal policy, not of any formal OECD or IRS recognition.
A Company Registration Number identifies your entity on the register. It carries no TIN status, and no compliance team is obliged to accept it as one.

Payroll Tax Registration and Employer Identifiers Explained
If your company hires staff in Bermuda, the picture changes slightly. Every employer and self-employed person liable for tax must register with the Office of the Tax Commissioner within seven days of the end of the first tax period in which business commences.
Failure to register is a criminal offence. Registration must also be completed with the Department of Social Insurance, and the process can be started through the government's tax account page.
The number you receive from this process is the payroll tax employer registration number. It is the closest thing Bermuda has to a functional employer tax number, yet it is still not a TIN under international definitions.
Keep the registration current. A new registration form and supporting documents are required on any change of name, ownership, or business structure, and an assessment may be levied if you close the business without notifying the Tax Commissioner.
The published format and length of this employer number are not disclosed by the government portal, which describes the obligation rather than the number's structure.
How Foreign Owners Handle the Missing TIN on CRS Self-Certification
The TIN field on Bermuda's CRS self-certification is marked optional, and for good reason: some account holders are resident in jurisdictions that issue no TIN. That design does not make the field cosmetic.
Reporting Financial Institutions must still include TINs in their reports in line with CRS due diligence. If you are personally tax-resident in a country that does issue TINs, you must supply your home-country TIN; the lack of a Bermuda number gives you no exemption from that obligation.
Accounts may be reported as "undocumented" only in the narrow circumstances set out in the CRS itself, and not otherwise. A financial institution that omits a required home-country TIN cannot simply default to "undocumented" to fill the gap.
Bermuda institutions also weigh residence-by-investment and citizenship-by-investment risk. The OECD has published a list of more than 25 potential high-risk schemes that can be misused to misrepresent tax residence, and local RFIs must take this into account when onboarding new account holders.

Tax ID Fields on FATCA and Banking Onboarding Forms
For FATCA, Bermuda's place on the IRS no-foreign-TIN list does real work. When an account holder resides in a listed jurisdiction, the withholding agent does not need to obtain a foreign TIN. The list names five places: Australia, Bermuda, the British Virgin Islands, the Cayman Islands, and Japan.
FATCA still has its own identifiers. A Global Intermediary Identification Number (GIIN) is issued by the IRS to entities treated as foreign financial institutions, and the Bermuda Ministry of Finance acts as the designated Tax Authority, with reports submitted through the Bermuda Tax Information Reporting Portal.
A GIIN is not a substitute for due diligence. Bermuda RFIs must not rely solely on the presence of a GIIN when validating self-certifications or classifying entity account holders for CRS.
Note that the two regimes are separate. Where an entity holds both a US TIN and a foreign TIN, the US TIN must be provided for FATCA, and information already given under FATCA may not satisfy CRS, which has its own requirements.
What to Enter When a Treaty or Withholding Form Demands a TIN
When a withholding form such as IRS Form W-8BEN-E presents a mandatory foreign TIN field, a Bermuda entity has no government-issued number to enter there. The number does not exist to be supplied.
US rules accommodate this. Because Bermuda is on the IRS no-foreign-TIN list, the withholding agent does not need to obtain a foreign TIN, and the agent may instead accept a "reasonable explanation" for its absence under Treasury Regulation §1.1441-1T(e)(2)(ii)(B).
There is no IRS-standardised wording for the Bermuda case. Practitioners typically state that "Bermuda does not issue TINs" and refer to the IRS list of jurisdictions that do not issue foreign TINs as the reasonable explanation.
For a non-US bilateral treaty form, the approach differs by counterparty. Cite the OECD's Bermuda TIN guidance and confirm the accepted wording directly with the counterparty's compliance team, since no uniform jurisdiction-by-jurisdiction protocol governs these forms.
Documents and Steps for Any Bermuda Registration That Substitutes for a Tax ID
Several registrations together produce the identifiers and certificates that stand in for a Tax ID in practice. Work through them in order, completing only the ones that apply to your business.
- Company formation. Register with the Registrar of Companies through its online portal. This produces the Company Registration Number, your primary official identifier.
- Payroll and employer registration. If you hire staff, register with the Office of the Tax Commissioner within seven days of the end of the first tax period in which business commences, generating a payroll tax employer number.
- Social Insurance. Register the business with the Department of Social Insurance.
- FATCA GIIN. Entities treated as foreign financial institutions register on the IRS FATCA portal to obtain a GIIN; the Bermuda Tax Information Reporting Portal then handles ongoing CRS and CbCR reporting.
Supporting documentation matters for banking. Certified documents and certificates of compliance can be ordered through the Registrar's portal, and these are the items most often submitted to banks and counterparties where a TIN substitute is requested.
Ownership disclosure runs alongside formation. Any owner holding more than 5% of the share capital must complete a statement of personal history and provide a certified copy of their passport, and the company must maintain a register of beneficial owners covering anyone who owns or controls more than 25% of shares or voting rights, or who otherwise exercises control.
Practical Implications and Outlook for Non-Resident Owners
Internationally, you are identified by your home-country TIN, the one issued where you are personally tax-resident, not by any Bermuda number. The absence of a local TIN changes how institutions report your information and what you must hand over at onboarding.
Banking friction is the most common practical hurdle. Compliance teams worldwide are trained to expect a TIN, so prepare the OECD Bermuda TIN document, your company registration certificate, and a short written explanation citing the IRS no-foreign-TIN list before an account is opened.
Reporting deadlines still bind Bermuda institutions, and missing them carries penalties. For the 2025 reporting year, CRS returns are due by 31 May 2026, and the Annual CRS Compliance Certification Form is due by 30 September 2026.
The exchange infrastructure is active despite the lack of a domestic TIN. Bermuda has signed double-taxation treaties with 41 countries and 9 Tax Information Exchange Agreements, supports the OECD BEPS minimum standards, and updated its Tax Information Reporting Portal User Guide in December 2025.
No legislative proposal to introduce a general TIN system has been identified. The position that no TIN is issued has held consistently and remains the figure confirmed to the OECD.
Conclusion
A Bermuda company will not receive a Tax Identification Number, because the jurisdiction issues none and has no income-tax system that would require one. What it does receive, a Company Registration Number and, if it employs staff, a payroll tax employer number, serves administrative purposes and carries no TIN status under IRS or OECD rules. The workable response for a foreign owner is documentary: keep the OECD Bermuda TIN guidance, your registration certificate, and a written explanation citing the IRS list ready for any form or bank that asks. Your own home-country TIN, not any Bermuda number, remains the identifier that follows you through CRS and FATCA reporting.

Frequently Asked Questions
No. Bermuda issues no Tax Identification Numbers or equivalent fiscal identifiers, a position officially confirmed to the OECD. A company receives a Company Registration Number from the Registrar of Companies, but that is an administrative identifier, not a tax number.
Leave the field without a number, since no government-issued TIN exists, and provide a reasonable explanation instead. Practitioners typically state that Bermuda does not issue TINs and reference the IRS list of jurisdictions that do not issue foreign TINs, which the withholding agent may accept under the relevant Treasury Regulation.
It cannot be legally treated as a TIN under OECD or IRS definitions, because Bermuda issues no TIN regime to give it that status. Some banks may accept the registration number as a substitute under their own internal policy, but this is a matter of institutional discretion, not formal recognition.
If you are personally tax-resident in a country that issues TINs, yes, you must provide your home-country TIN. The absence of a Bermuda TIN does not relieve you of that obligation, and Reporting Financial Institutions must include TINs in their reports in line with CRS due diligence.
It is the payroll tax employer registration number issued by the Office of the Tax Commissioner. Employers must register within seven days of the end of the first tax period in which business commences, though this number is still not a TIN under international definitions.
For the 2025 reporting year, the CRS return is due by 31 May 2026, and the Annual CRS Compliance Certification Form is due by 30 September 2026. Penalties may apply for missing these deadlines, and reports are submitted through the Bermuda Tax Information Reporting Portal.
